Pellet sell-it: Manufacturing Feed Pellets
The Feed Pellet machine has multiple angles in which someone can operate a business. Being realtivley cheap to start up wit ha price of under $10000, it can be a good investment for developing or developed countries depending on where one lives. Let's take a close look at the numbers and how they can be incorporated into the business model for starting a pet food brand using a fish feed granulator:
Power: 15KW
Staff: 1
Area: 20M2
Raw Materials: Amino acids, stalks, cereals, oils, etc.
Environmental Impact: LOW
Production Capacity: 150KG/HOUR
Other Produce: Dog feed, pig feed, cat feed, etc.
Minimum Budget: $100-$10,000
More details...
To calculate the production cost of pet food pellets, you need to consider the cost of raw materials, labor, and electricity.
Raw Materials Cost: The cost of raw materials depends on the type and quality of the ingredients used. Let's assume that the raw material cost for producing 1kg of pet food pellets is $1.
Labor Cost: Since the staff requirement for operating the fish feed granulator is only one person, let's assume a monthly salary of $1000.
Electricity Cost: The power consumption of the fish feed granulator is 15KW per hour. Let's assume that the cost of electricity is $0.10 per KW. So, the electricity cost for producing 1kg of pet food pellets is $1.50.
Therefore, the total production cost for 1kg of pet food pellets would be:
Raw Materials Cost + Labor Cost + Electricity Cost = $1 + $1000/30 days + $1.50 = $33.17 per 150kg produced per hour.
Assuming you sell the pet food pellets at a price of $2 per kg, your revenue for producing 150kg per hour would be $300.
Starting a pet food brand using a fish feed granulator has numerous advantages, including small area requirements, low environmental impact, high production capacity, the ability to produce multiple types of animal feed, manageable electricity usage, and a low minimum budget. With these advantages, there are various business models that you could consider while starting your pet food brand:
Direct Sales to Pet Owners: You can sell your pet food pellets directly to pet owners through pet stores, online marketplaces, and social media channels. This model is ideal if you are targeting a specific niche market such as organic or grain-free pet food. The high production capacity of the fish feed granulator allows you to fulfill customer demand quickly, while the low environmental impact aligns with the values of environmentally conscious pet owners.
Wholesale to Pet Stores: Another option is to sell your pet food pellets in bulk to pet stores, veterinary clinics, and animal shelters. The high production capacity of the fish feed granulator makes it easier to supply large quantities of animal feed, while the low minimum budget and manageable electricity usage enable you to offer competitive pricing to retailers.
Private Labeling: Private labeling your pet food pellets can be a profitable business model as it allows you to sell under a pre-existing brand name. You can offer custom formulations to different retailers to cater to their unique customer base. The ability to produce multiple types of animal feed using the fish feed granulator allows you to cater to the specific needs of each retailer. Combing this method with an automatic labeling machine can further automate your business.
Online Sales: Establishing an e-commerce website is essential in today's digital age, allowing pet owners to order your pet food pellets online. A strong online presence with effective marketing strategies like SEO optimization, email marketing, and social media advertising can help you reach a wider audience. The low minimum budget and manageable electricity usage also make it easier to maintain profitability with online sales.
Distribution Partnership: Partnering with a distributor can help expand your pet food brand reach to new markets. The high production capacity of the fish feed granulator enables you to supply large quantities of animal feed to distributors, while the low environmental impact aligns with the values of environmentally conscious distributors.
Value-Added Services: Offering value-added services such as nutrition consultation, feed formulation, and pet care services can differentiate your brand from competitors and add value to your business. The ability to produce multiple types of animal feed using the fish feed granulator allows you to offer a wide range of value-added services to pet owners and retailers.
Food pellets are also used as a source of energy for cooking and heating in some parts of the continent. Pellets made from agricultural waste, such as rice husks and sawdust, can be burned in specially designed stoves to provide a cleaner and more sustainable alternative to traditional fuels like charcoal and firewood. Using this alternate method of energy creation, there are new avenues to explore.

Ghana Fish Feed Production Machine And Fish Farming Market
http://www.feedpelletmills.com/blog/fish-feed-pellet-line/ghana-fish-farming-market.html
The growing global and national demand for fish and the dwindling supply of the Ghanaian economy is another reason for the development of aquaculture. In Ghana, more and more people are shunning red meat as a source of protein and turning to fish because of the health effects.  
Fish feed pellet machine can make fish feed pellets, Zhengzhou Fusmar Machinery is a professional fish feed extruder manufacturer. If you want to build your own fish feed plant, please contact us.
Aquaculture Market in Ghana
These are the main drivers of the market and the industry. Also due to the role of fisheries in its contribution to GDP, the government has promoted aquaculture as a means of increasing the annual decline in ocean fishing, providing food and employment to the population.
Ghana has a high domestic demand for fish and one of the highest per capita consumption rates in the world (20-25 kg/year). Rapid population growth and urbanization mean that Ghana’s aquaculture market is also expanding, un-habitat predicts. Currently, 87% of households in Ghana are recorded as consumers of tilapia, especially smokers. Ghana also spends heavily on hotels, restaurants, and other food services.
Extruders For Fish Feed Production
Fish feed extruder is used to produce extruded pet food, (floating) extruded aquatic feed and extruded animal feed.
The extrusion cooking process will lead to a large number of starch gelatinization, so the feed has good water stability. It can produce both “extruded” floating feed and sinking feed. The process also improves the digestibility of the product.
Fish feed pellets that contain ingredients such as soybean meal and cereal grains are more digestible and therefore more nutritious. Floating feed is made by extruder machine, and sinking feed with high water stability can also be made by extruder machine. In some cases, extruders are used only to prepare feed materials, such as the dry extrusion of soybeans.
Basically, the extruder is a long barrel with an auger that is specifically designed to expose the incoming mixture to high heat and steam pressure. When the feed comes out of the die at the end of the barrel, the captured steam is quickly blown away, and the soft warm pellets expand, producing a low-density floating pellets. The extruder is widely used and can be made into feed with many different characteristics.
Fish Feed In Ghana
Feed constitutes the highest production cost (above 60%) in fish farming, especially in cage farming where complete floating feeds are used. Floating feeds are partly imported and produced in Ghana. The price of fish feeds fluctuates depending on the availability and prices of raw material on international markets. Locally manufactured feeds are on average 30% cheaper than imported feeds.
In Ghana, fish feed is imported duty-free and operated by the private sector. All imported feeds are float-expanded feeds with particle sizes ranging from 0.3 mm to 6 mm. Powder/shredded fish feed is also imported.
Beside commercially produced feeds, farm-made feeds and supplemental feeds (agriculture by-products) are being used locally, mainly in pond farming. The formulation of farm-made feeds is mainly depending on the costs of ingredients rather than the nutritional requirement of the fish. Feeds are pelletized using simple other purpose build electric devices and presented to fish either as wet doughs and moist feeds during the rainy season and as dried feeds during the dry season. Very few farmers use premixes in the feeds. Farm-made feeds are poorly bound and quickly disintegrate in contact with water. They are also poorly digestible. Small-scale pond farmers practice supplemental feeding additional to pond fertilization. Common supplemental feed ingredients are wheat bran, maize bran, rice bran, and other cereal brans, which are readily available on the market. A minority of pond farmers use commercial floating feeds.

Breeding Mode of Tilapia
1. Intensive cultivation mode
The intensive cultivation mode of tilapia developed rapidly in the past few years. Intensive cultivation, that is, pure tilapia cultivation, can produce more than 5,000 kilograms per mu, creating a lot of tilapia myths. The representative areas of the intensive breeding model are tropical and subtropical breeding areas such as Wenchang, Hainan and Nanning, Guangxi. Ponds need to be equipped with strong oxygenation capacity, and ponds with good conditions even have sewage systems.
Hainan, taking advantage of its unique climate, can raise three fish a year; Nanning, on the other hand, relies on its advantages in the domestic market, and the price of fish has been relatively strong. Tilapia in intensive culture mode grow fast and yield high, so they are highly respected by farmers in the two places. In addition, the peak market period of tilapia is from October to December, which is also the time when the price is the lowest. Tilapia under the intensive culture mode can be listed one month earlier, and farmers can make a time difference to avoid the peak fish output and impact the fish price.
However, in the past two years, intensively cultured tilapia has faced the double test of streptococcosis and weak exports. Under the circumstance that the market situation in the past two years is still unclear, many large tilapia farmers are still in a wait-and-see mood.
2. Tilapia-shrimp polyculture mode
The tilapia-shrimp polyculture model can be regarded as a relatively classic breeding model, which is also due to the frequent occurrence of shrimp diseases and the downturn of the tilapia market in recent years. This pattern is distributed in Taishan, Zhuhai, Zhanjiang and Maoming in Guangdong.
The tilapia-shrimp polyculture model is dominated by tilapia and supplemented by prawns. The two complement each other and improve the ability to resist risks. Farmers generally start to label rough tilapia fry and shrimp fry in the middle and late March. The seedling density of tilapia is 2500-3000/mu, and the shrimp fry is 20000-30000/mu, mainly the second generation. After the standard thickness, the size of tilapia fry reaches 50/catties, and when the size of shrimp fry reaches 800/catties, tilapia and prawns can be mixed in ponds. 
The prawns can be harvested at the beginning of June, and the land cages are used for catching. The annual output per mu is about 200 catties. Calculated at an average price of 15-20 yuan/catties, the per-mu output value of prawns is 3000-4000 yuan, which can offset most of the tilapia. feed expenditure. Tilapia can be marketed in batches in mid-September, with a bait coefficient of about 1.3 and a yield of 2,500-3,000 catties per mu. Taking advantage of the high value-added characteristics of prawns, this model can greatly improve the farming income of tilapia. So you can see the dry type fish feed pellet machine in Lima.
3. Intensive breeding of large-sized tilapia
In recent years, the market for large-sized tilapia of 3-4 catties has been very stable, with an average price of about 10 yuan / catty, and the profit margin is not small. It is chased by some farmers. The breeding areas are mainly concentrated in Zhuhai and Foshan. Near high-consumption cities. In this mode, the seedlings are generally invested in March, and the amount of seedlings per mu is 3000-4000 (size 7-8). After 3 months of breeding, farmers can choose to remove some commercial fish or separate ponds for breeding to speed up capital. Turnover and reduce farming risks in hot seasons. After raising until the end of the year, the size of tilapia reaches 3-4 kilograms, and farmers can produce fish in batches according to market conditions. Taking the farmers in Pingsha, Zhuhai as an example, under this model, the annual output of tilapia can reach 6,000 kilograms, and the profit per mu is as high as 12,000-15,000 yuan.
Although profitable, this farming model is only suitable for farming areas close to wholesale markets or urban consumer groups. These areas not only have strong consumption capacity for large-sized tilapia, but farmers can also directly connect with the market to obtain greater profit margins.
In addition, raising large-sized tilapia must overwinter, because the price of tilapia is the highest after the year when the green and yellow are not in contact. Whether it can survive the winter has become the most concerned issue for tilapia farmers. Therefore, this model is only suitable for ponds with winter sheds and sufficient groundwater or geothermal heat. This model has a long breeding cycle and high cost. Farmers should choose according to their own pond environment and market environment, and do not blindly follow the trend.
4. Three-dimensional breeding mode
Stereoscopic farming includes traditional fish-duck polyculture and fish-pig polyculture, which are mainly concentrated in eastern Guangdong and inland large-water aquaculture areas. Taking the mixed breeding of fish and ducks in eastern Guangdong as an example, the stocking density of tilapia is 800-1000 tails/mu (size 8-9), and it is also matched with filter-feeding and omnivorous fish such as bighead carp, silver carp and dace. kind. Feeding open feed in the fry stage to improve the survival rate, no feed or less feed in the middle of the breeding period, when the fish reaches a size of more than half a catty, they start feeding tilapia feed for fertilization, and some farmers will feed duck feed when they are waiting for the price of fish . The bait coefficient of the whole process is about 0.6-0.8, and the breeding cost is 2-3 yuan/catties.
According to an industry personnel analysis, the cost of intensive tilapia culture is generally 3.5 to 4 yuan per kilogram, polyculture is 3 to 3.5 yuan per kilogram, and the cost of three-dimensional culture is 2 to 3 yuan per kilogram. Under the current situation, the first two breeding modes are loss-making transactions. Therefore, for now, three-dimensional farming is still the best farming mode for tilapia farmers to avoid market risks.
In the short term, the three-dimensional breeding model will not disappear, but as the policy level shifts and the breeding industry and environmental protection are linked, the government will strengthen the management and control of the pond breeding environment.
Some areas have banned the construction of pig houses and duck sheds in ponds. In the long run, farmers still have to make timely changes to cope with changes in the general environment.
Welcome to see the fish feed making machine for production line in Lima.

Gun Detection AI is Being Trained With Homemade ‘Active Shooter’ Videos
In Huntsville, Alabama, there is a room with green walls and a green ceiling. Dangling down the center is a fishing line attached to a motor mounted to the ceiling, which moves a procession of guns tied to the translucent line.
The staff at Arcarithm bought each of the 10 best-selling firearm models in the U.S.: Rugers, Glocks, Sig Sauers. Pistols and long guns are dangled from the line. The motor rotates them around the room, helping a camera mounted to a mobile platform photograph them from multiple angles. “It’s just like a movie set,” said Arcarithm president and CEO Randy E. Riley.
This process creates about 5,000 images of each gun floating ethereally. Arcarithm’s computer programmers then replace the green backdrop with different environments, like fields, forests, and city streets. They add rain or snow or fog or sun. A program then randomly distorts the images. The result is 30,000 to 50,000 images of the same gun, from multiple angles, in different synthetic settings and of varying degrees of visibility.
The point of creating this vast portfolio of digital gun art is to feed an algorithm made to detect a firearm as soon as a security camera catches it being drawn by synthetically creating tens of thousands of ways each gun may appear. Arcarithm is one of several companies developing automated active shooter detection technology in the hopes of selling it to schools, hotels, entertainment venues and the owners of any location that could be the site of one of America’s 15,000 annual gun murders and 29,000 gun injuries.
Among the other sellers are Omnilert, a longtime vendor of safety notification software, and newcomers ZeroEyes, Defendry, and Athena Securities. Some cities employ a surveillance system of acoustic sensors to instantly detect gunshots. These companies promise to do one better and save precious minutes by alerting police or security personnel before the first shot is fired.
They are all maneuvering around a problem: Algorithms, at their most basic level, collect data that is categorized, so they can independently determine if something new is of that category. In the tech industry, it’s generally believed that more data means a sharper algorithm. For companies that want to detect gunmen, therein lies one dilemma.
Tumblr media
Screenshot from a promotional video for Omnilert's Gun Detect software
Visual detection machine learning has been developed for a wide range of uses, including diagnosing medical conditions and identifying pedestrians in a roadway. Researchers behind those efforts have access to nearly limitless pictures of tumors and inflammation and videos of joggers or dog walkers.
However, due to sensitivity, little footage from the start of shootings is readily available, certainly not enough to program a system that is supposed to differentiate a gun from a cell phone or a hairbrush reliably hundreds or thousands of times a day. Such footage is scrubbed from all but the darkest corners of the internet. There’s no inventory of it on Roboflow, Amazon Mechanical Turk, and other libraries of images for machine learning (though Roboflow does have a supply of still photos of guns).
The reliability of gun detection systems is of serious consequence to the people they monitor. This year, the Lockport City School District, in Upstate New York, implemented an algorithmic system to recognize faces and detect weapons. The technology misidentified black children at a higher rate, and emails between employees of its creator, ST Technologies, show the Canadian company was struggling to stop the system from mistaking broom handles for guns after it was implemented.
“I have concerns about the reliability of the object detection system and that system misidentifying a student holding a baseball bat and [police] will go and harass that student with a baseball bat,” said Daniel Lawrence, a researcher at the Urban Institute’s Justice Policy Center, who has studied technology in crime detection.
Alternatively, Lawrence said, police tend to take these alerts less seriously if they are always detecting low-priority activity or making false positives. “Everything depends on accuracy,” he said.
To train a computer program to recognize a gun as soon as it’s drawn—and then to test that program—companies have to get creative. And a bit weird.
Arcarithm, founded as a military and security contractor by three former Lockheed Martin employees, started by programming cameras to detect drones overhead. A client challenged them to come up with a system to detect guns. “If we can do drones, we can do anything,” said Riley, “so we spent the next ten years trying to tell if a guy has a gun or a broom and it turns out we can.”
Theoretically, the vast array of distortions and alterations in images feeding Arcarithm’s algorithm would account for ways a gun is obscured in real footage—by hands, by climate, or by distance. Through seeing so many common guns so many ways, the algorithm would supposedly become so familiar with guns, it could spot one instantly.
To test if their algorithm responds to the intended stimuli, Arcarithm staffers have staged armed invasions of their own headquarters using airsoft guns, which use condensed gas to shoot tiny, non-lethal plastic pellets. They’ve also taken to a nearby field to record themselves. It is programmers and desk employees cosplaying as criminals or militiamen. “All the guys are doing it,” said Riley. “They usually work on the development end.” He adds that they warn the sheriff’s department, which usually sends an observer.
Arcarithm has not found any buyers outside the U.S. military, which seeks an alert system for armed people coming towards a base. Riley said he has approached the operator of a theme park and a school system near Huntsville.
Of the other U.S. companies selling gun detection technology, Athena did not respond to an interview request from Motherboard, and seems to have pivoted to making a dubiously marketed technology that monitors people’s temperature amidst the COVID-19 pandemic. A spokesperson for ZeroEyes said its technology is proprietary so they would not discuss it. A representative for Defendry said the company declined because it did not want its name in an article published by VICE Media.
Omnilert has supplied notification systems, mainly to colleges and universities, since 2003, and unveiled its Gun Detect software in October.
CEO Dave Fraser describes a kitchen sink approach to the data-to-feed-the-algorithm problem. His company has used technology made to produce video games to create CGI simulations of the first moments of hold-ups and shooting sprees. They’ve trained the algorithm on Hollywood movies (he named John Wick). And there is also what Fraser dubbed “pajama videos,” homemade clips of employees walking around with guns (real and toy) recorded in their homes during the COVID-19 remote work months. He’s also outsourced the task to a few video content creators.
“We’ve built up an internet database of ourselves and our contractors brandishing guns,” said Fraser. “We have thousands of hours of data we created and we own.” Homemade videos are used to both feed and test the algorithm.
The videos fill up the company Slack channel, he said. And programmers and other desk employees are tasked with creating them.
Even their public director of marketing, Elizabeth Venafro, has contributed self-filmed clips of herself marching through her home toting a toy rifle, which “felt very weird, as a non-gun-owner,” she said.
Tumblr media

Experts in academia say that machine learning can now identify objects, even from a distance, but the process hinges on sufficient data.
“Today, we are much better than we were five years ago,” Ali Farhadi, an associate professor at the University of Washington working in computer vision and machine learning, told Motherboard. “We can detect objects fairly reliably.” Each year, smaller and more specialized objects are detectable and computer scientists can program algorithms to identify the body motions and context around them. “Not only can we see scissors but we know how people act when they are cutting things,” he said.
Visual identification requires a vast amount of varied data. Even differences in the sun path between the northern and southern hemispheres and subtle differences in background scenery can cause the program to be less effective, he said. “You want something that works as well in American cities as Indian cities,” said Farhadi. It’s even best to get footage from the types of cameras one expects to be in the field obtaining the feed, he said.
Karthik Ramani, a professor in mechanical engineering at Purdue University, completed a project that trained computer learning to identify mechanical objects so as to help engineers find exact matches and replacements. Machine learning is capable of identifying detailed objects, he said, but synthetic data is no replacement for the thing.
In CGI-created images, “I was seeing a loss of energy,” said Ramani. “You don’t get the real-world noise and reflections and metals are shiny and things can get confused. As humans, we see this and we get used to it. The machine doesn’t know these things yet.”
Some false positives are inevitable, Fraser and Riley both conceded. But both claim the technology can give first responders a few precious minutes, or seconds, to save lives.
Lawrence, of the Urban Institute, said once any surveillance or analytic technology comes into the hands of police departments, it's inevitably used to target poor, minority areas. “It is over-applied in communities with persons of color,” he said. Such neighborhoods are disproportionately policed, and the use of technology like predictive policing is a major driver of those statistics, creating a feedback loop.
“This technology is very expensive and it makes no sense to have it applied to the entire city,” he said.
However, Lawrence does not think cities will buy gun detection software in the near future. The summer racial justice protests and the “defund the police” movement have caused cities to shrink from buying expensive, futuristic equipment for police purposes. “I think as a society, we are redefining what policing is and how much money should be allotted to what and how much money should go to the police,” he said. “I think we are on the precipice of using money to combat crime and the causes of crime in a different way.”
He thinks the buyers of the next generation of gun detection software will be private companies, but once a gun is thought to be detected, “the call will go to the police.”
It is widely acknowledged that the ubiquity of guns in the United States is one reason the number of police killings in the U.S. dwarf those of other countries. Police shootings of Black people sometimes begin with the excuse that the officer thought the person had a gun, including the deaths of Casey Goodman, Stephon Clark, Tamir Rice, and Amadou Diallo. During a traffic stop, Philando Castile informed an officer he possessed a legal gun and the cop immediately  opened fire.
Like many companies who make automated systems, Omnilert defends its gun-detection technology by noting that the final decision is made by a human being. “It could automatically lock the door on a suspect,” said Riley. “Now it’s up to the police to show up and see what this person does.”
As for a police overreaction, Fraser said, “It’s a possibility. We tend to look at this as ‘no technology is perfect.’ We tend to think it’s a positive to put this technology in our customer’s hands rather than have them rely on hearsay or gunshots when it’s too late.”
The possibility is enough for Meredith Whittaker, faculty director of the AI Now Institute at New York University, to reject the use of the technology outright. Whittaker and other AI ethicists and scholars have noted that all algorithmic systems contain bias, and this fundamental flaw can't simply be fixed with more data or a software update.
“They shouldn’t purchase anything like this,” she said of those who would buy gun-detection technology. “There is no dataset that would make this work. They are flawed, they are racist and they are being put into schools.”

Single Use Plastic Project
What are single use plastics?
Single-use plastics, or disposable plastics, are used only once before they are thrown away or recycled. These items are things like plastic bags, straws, coffee stirrers, soda and water bottles and most food packaging.
Plastic bottles are the most commonly collected plastic packaging type. This is because they are easy to sort and there are well developed markets for the recyclate. The bulk of bottles are made from PET or HDPE, which account for about 90%.
Note: The UK has a much higher use of HDPE bottles than most countries due to its use for containing milk.
Plastic bottles are normally made from one of only four polymer types and are very easily identified, both by members of the public and those sorting the collected bottles. The four polymer types used are:
PET (e.g. fizzy drink bottles and squash bottles)
HDPE (e.g. milk bottles and detergent bottles)
PP (e.g. ketchup bottles)
PVC (e.g. large squash bottles). Although the use of PVC  in such applications is in decline
How the UK deal with plastic
Plastics are processed in the UK and abroad. Plastics are separated from your other recyclables at a facility in London and sorted into the different plastic types, including plastic bottles and mixed plastics, such as pots and trays.  Plastic bottles are predominantly sent to facilities in the UK for remanufacturing - they are washed and chipped to create plastic pellets which can be remade into plastic bottles. The other mixed plastics are sent to outlets in the UK and overseas for manufacturing into new products.
“None of the recycling we collect is incinerated or sent to landfill unless it is too contaminated to be processed.”
Once the material is sorted, it is sent to reprocessing companies to be turned into new materials and products. Some of these recycling markets are in the UK while others are based outside of the UK. The recycling gets sent to where there is a reliable and financially sound market for the materials.
At present, much of the manufacturing industry that the UK relies on is in the Far East and therefore, some of the material has to be sent there. The material gets turned into a vast range of products, from kitchen appliances, to toys, clothes and packaging.

More than 40 companies, including Procter & Gamble, Coca-Cola and Asda, have signed up with the government, trade associations and campaigners to form the UK Plastics Pact.
The Pact says it’s a once-in-a lifetime opportunity to rethink the way we use plastic and its impact on the environment.
Recently, the government said it was considering banning plastic straws and cotton buds and this came hot on the heels of a proposal to make consumers pay a deposit on drinks bottles and cans.
Bans on plastic products
A major step to expand the reduction of plastics beyond bud, straws and stirrers has been announced in the UK Plastics Pact.
Apart from packaging, two of the biggest plastic problems are straws and ear buds. These are among the most widely used items that turn up on beaches around the UK.
Plastic cotton buds are often flushed down toilets and are small enough to pass through water filter systems and end up being eaten by fish and other marine creatures.
The scale of UK plastic straw use is staggering with a figure of eight-and-a-half billion thrown away each year. The government is consulting on these steps with a possible ban to be introduced next year.
Tumblr media
Last December, 193 countries committed to a UN plan to stop plastic waste entering the oceans. However, the commitment is not legally binding and doesn’t have a timetable. And different countries have adopted different schemes.
Around 40 have banned single-use plastic bags, with charges or outright prohibitions in place in China, Rwanda and many others including Bangladesh.
Others including the UK are moving to ban plastic straws and cotton buds. Zero plastic waste shops are opening in many towns and cities while plastic-free aisles in stores was part of the 25-year plan for nature in the UK put forward by Prime Minister Theresa May.
Encouraging the Public
some countries are beginning to create collection points for plastics such as bottles in order to encourage more people to properly recycle their waste rather than just throwing it into a regular bin. By doing this, those who hand in plastics will also be rewarded with a small amount of money per plastic, in order to give motivation. Some countries which already operate a similar deposit system have installed “reverse vending machines” to automate the process of reclaiming a deposit.Many of these machines are able to sort, crush and store used bottles.So-called “reverse-vending” has operated since 1984 in Sweden, where more than 90% of household waste is recycled.
Facts on single use plastic
by 2050 the ocean will contain more plastic (by weight) than fish. Studies also found that tiny particles of plastic are already in our food chain and an average person who consumes seafood ingests 11,000 tiny pieces of plastic per year.
full 32% of the 78 million tons of plastic packaging produced annually is left to flow into our oceans; the equivalent of pouring one garbage truck of plastic into the ocean every minute.

Tumblr media
Effects plastics have on the environment and animals
Much is made of plastic’s impact on our marine environments. And rightly so given the massive destruction that plastics can wreak on our oceans. With 80 percent of marine garbage being land-based, 90 percent of that is estimated to be plastic. Unlike other materials, plastic never truly decomposes, it simply breaks into smaller bits that will remain in the oceans forever as a sort of microscopic plastic soup.
Chronic Hunger “The really sad thing about this is that they’re eating plastic thinking it’s food,” says Matthew Savoca, a marine biologist with the National Oceanic and Atmospheric Administration. “Imagine you ate lunch and then just felt weak and lethargic and hungry all day. That would be very confusing.”
Tumblr media
Plastic stands to cause intestinal blockages in an animal that consumes it. Death is the ultimate tragedy for animals that consume plastic and this is a sad fate that both wild and domestic animals alike can face.
As plastic bags can take up to 1,000 years to break down, once an animal dies and decays after ingesting plastic, the plastic is then freed back into the marine environment to carry on killing other wildlife.
An animal with its head stuck in a plastic food container may suffer from overheating, suffocation, dehydration, starvation, and eventual death from these elements. It is also not equipped to defend itself from a threat.
Tumblr media
In August 2000, an eight metre Bryde’s whale died soon after becoming stranded on a Cairns beach. An autopsy found that the whale’s stomach was tightly packed with 6 m2 of plastic, including many plastic check-out bags. Such obstructions in animals can cause severe pain, distress and death.
Bryde’s whales, like many other types of whales, feed by swallowing large amounts of water. If the Bryde’s whale had died at sea, it would have decayed, releasing the plastic to kill other marine life for hundreds of years to come.
Tumblr media
In 1998, a pelican was found dead in Kiama after eating 17 plastic bags.
The pelican presumably thought the plastic bags were food. The pelican was preserved and named Pete. Since then he has been standing in front of a sign at Fitzroy Falls that informs visitors of how he died and the problems of plastic bags and ocean pollution.
Tumblr media
How to reduce single use plastics
Reduce, Reuse and Recycle
Even when single-use plastics are sent to landfills (there are 3,091 active landfills in the U.S. alone), they aren’t harmless. Landfill liners can leak harmful pollutants into the watershed and plastics on the tops of landfills can be carried away by the wind.The best way to curb single-use plastic pollution is to reduce your personal plastic consumption!
In order to reduce paper cup waste, are the schemes of a few coffee chains, like Pret A Manger, who introduced a discount of 25 to 50 pence if you bring our own reusable mug. They hope this incentive may help change consumer habits. Besides saving in your morning coffee expenditure, you will also be helping to reduce wastage sent to landfills.
Tumblr media
Americans purchase about 50 billion water bottles per year, averaging about 13 bottles per month for every person in the U.S.! That means by using a reusable water bottle, you could save an average of 156 plastic bottles annually.
You can easily reduce your plastic bottle consumption by:
Installing a filter system in your house or purchasing a filtering jug
Getting a reusable water bottle
Drinking tap water when possible
Tumblr media
Half a million straws are used in the world every day. Refusing straws is becoming a trending practice!
Next time, rethink and refuse plastic bags! There are many alternatives to plastic shopping bags, like canvas bags, reusable bags, backpack, or even cardboard boxes. Try to always carry a reusable bag with you and try to avoid plastic bags next time you go shopping.

Idea Development
The angle I am going to take on this project will be through the impact on all animals, aquatic and land-based, however my focus will be aquatic. Due to the period making it a bit difficult to fit both in along with other information, I will see how I progress to determine how much of each I will put time into.
Tumblr media
My animation will begin on some basic, short facts on plastic, where it comes from, how long it takes to degrade etc., and then move over onto the impact it has on animals due to this. If I can find free use photos of animals in situations caused by plastic, I will use some, but if not I will use illustrator to make vectors of them (this would also be good as I could animate them).
Tumblr media
The video will then move over to things we can do to help animals, and ourselves, including a few ideas of recycling, and a few countries that are making huge movements in reducing plastic consumption.
Tumblr media
My animation will be designed with a cute theme, with most of my art coming from illustrator vectors, and I’m thinking of creating a sort of mascot turtle that will go through the video with the viewer to explain everything. The video will include mostly soft, complementing colours, and then I would save contrasting colours for important messages in the text, or for certain bits of art to draw attention to that point.  
I want to use quite soft music to match the video, perhaps a piano piece or just relaxing music in general, but I will be able to pinpoint the best sounds once I have made a firmer design of my animation.

Fish Feed Pellet Microwave Drying Machine
Tumblr media
With the development of the situation, the market of microwave drying machine has developed rapidly, and the production enterprises have also made good achievements, innovations in technology and increasing benefits. In fact, drying has a long history, as early as ancient times, people began to use natural conditions for material drying. With the development of the times, they are gradually replaced by manual operation. Instead, microwave drying equipment has gradually developed.
Tumblr media
Characteristics of Fish Feed Pellet Microwave Drying Machine:Energy Saving of Microwave Drying Equipment.Because the substance containing water is easy to absorb microwave and heat, there is almost no other loss except a small amount of transmission loss. Therefore, it has high thermal efficiency and energy saving. Microwave drying equipment can save more than 1/3 energy than infrared drying.Microwave drying equipment dries rapidly.Microwave drying equipment is completely different from traditional drying methods. It is a process in which the dried material itself becomes a heater without heat conduction.
Tumblr media
Safety and harmlessness: Because microwave energy of microwave drying equipment is controlled to work in metal drying chamber and waveguide tube, microwave leakage is very little, there is no radiation hazard and harmful gas emission, no waste heat and dust pollution, neither food pollution, microwave drying equipment nor environmental pollution. Anti-mildew, sterilization and preservation of microwave drying equipment.Microwave drying equipment has thermal and biological effects. Microwave drying equipment can sterilize and prevent mildew at lower temperature. Because of its fast drying speed and short drying time, it can preserve the activity of materials and vitamins, original color and nutritional ingredients in food to a great extent. Advanced Technology.As long as microwave power is controlled, microwave drying equipment can achieve immediate drying and termination. The programmable automatic control of drying process and drying process specification can be carried out by using man-machine interface and PLC.
Microwave drying equipment is a kind of microwave drying equipment, which is obtained by the special movement of electrons in the magnetic field through DC or 50Hz alternating current on the electro-vacuum device or semiconductor device. This motion can be explained simply as follows: from the point of view of dielectric structure, one kind of molecule is called electrodeless molecular dielectrics, the other is called polar molecular dielectrics. Microwave drying equipment in general, they are arranged irregularly.In an alternating electric field, the polar molecular orientation of these media changes with the polarity of the electric field, which is called polarization. The stronger the applied electric field is, the stronger the polarization effect of microwave drying equipment will be. The faster the polarization of the applied electric field changes, the faster the polarization will be. The more intense the thermal movement of molecules in microwave drying equipment and the friction between adjacent molecules will be. In this process, the conversion of electromagnetic energy to thermal energy is completed. When the heated material is placed in the microwave field, the polar molecules of microwave drying equipment swing and rub back and forth with the microwave frequency of billions of times per second. The heat generated by microwave drying equipment is enough to make the material hot-dry in a very short time.

The Prophets of Cryptocurrency Survey the Boom and Bust
The Prophets of Cryptocurrency Survey the Boom and Bust
Not long ago, I was in Montreal for a cryptocurrency conference. My hotel, on the top floor of a big building downtown, had a roof garden with a koi pond. One morning, as I had coffee and a bagel in this garden, I watched a pair of ducks feeding on a mound of pellets that someone had left for them at the pond’s edge. Every few seconds, they dipped their beaks to drink, and, in the process, spilled undigested pellets into the water. A few koi idled there, poking at the surface for the scraps. The longer I watched, the more I wondered if the ducks were deliberately feeding the fish. Was such a thing possible? I asked the breakfast attendant, a ruddy Quebecer. He smiled and said, “No, but it is what I tell the children.”
My mind had been marinating overnight—and for more than a year, really—in the abstrusities of cryptocurrencies and the blockchain technology on which they are built. Bitcoin and, subsequently, a proliferation of other cryptocurrencies had become an object of global fascination, amid prophecies of societal upheaval and reform, but mainly on the promise of instant wealth. A peer-to-peer money system that cut out banks and governments had made it possible, and fashionable, to get rich by sticking it to the Man.
Some of this stuff I understood; much of it I still did not. If you’re not, say, a computer scientist or a mathematician, the deeper you get into the esoterica of distributed ledgers, consensus algorithms, hash functions, zero-knowledge proofs, byzantine-fault-tolerance theory, and so on—the farther you travel from the familiar terrain of “the legacy world,” where, one blockchain futurist told me, pityingly, I live—the better the chance you have of bumping up against the limits of your intelligence. You grasp, instead, for metaphors.
Blockchain talk makes a whiteboard of the brain. You’re always erasing, starting over, as analogies present themselves. So, Montreal bagel in hand, I considered the ducks and the carp. Let the pellets be a cryptocurrency—koicoin, say. Would the ducks then be currency miners? Every altcoin—the catchall for cryptocurrencies other than bitcoin, the majority of which are eventually classified as shitcoin—has its own community of enthusiasts and kvetchers, so perhaps the koi were this one’s. The koicommunity. The breakfast attendant who had put out the pellets: he’d be our koicoin Satoshi—as in Satoshi Nakamoto, the pseudonymous and still unidentified creator of Bitcoin. Yes, the koicoin protocol was strong, and the incentives appeared to be well aligned, but the project didn’t really pass muster in terms of immutability, decentralization, and privacy. Koicoin was shitcoin.
A few hours later, I was at lunch in a conference room in another hotel, with a table of crypto wizards, a few of them among the most respected devs in the space. (Devs are developers, and even legacy worlders must surrender after a while and ditch the scare quotes around “the space,” when referring to the cryptosphere.) Four of these devs were researchers associated with Ethereum, the open-source blockchain platform. Ethereum is not itself a cryptocurrency; to operate on Ethereum, you have to use the cryptocurrency ether, which, like bitcoin, you can buy or sell. (Among cryptocurrencies, ether’s market capitalization is second only to bitcoin’s.) The devs were specimens of an itinerant coder élite, engaged, wherever they turn up and to the exclusion of pretty much everything else, in the ongoing construction of an alternate global financial and computational infrastructure: a new way of handling money or identity, a system they describe as a better, decentralized version of the World Wide Web—a Web 3.0—more in keeping with the Internet’s early utopian promise than with the invidious, monopolistic hellscape it has become. They want to seize back the tubes, and the data—our lives—from Facebook, Google, and the new oligarchs of Silicon Valley.
One of them, Vlad Zamfir, a twenty-eight-year-old Romanian-born mathematician who grew up in Ottawa and dropped out of the University of Guelph, was scribbling equations on an electronic tablet called a reMarkable pad. He narrated as he scrawled. The others at the table leaned in toward him, in a way that recalled Rembrandt’s “The Anatomy Lesson of Dr. Nicolaes Tulp.” To the two or three people at the table who were clearly incapable of following along, he said, earnestly, “Sorry to alienate you with my math.” Zamfir is the lead developer of one strand of Casper, an ongoing software upgrade designed to make Ethereum scale better and work more securely—an undertaking thought to be vital to its viability and survival. “It’s shitty technology,” Zamfir, whose Twitter bio reads “absurdist, troll,” told a journalist two years ago.
Zamfir was showing the others some rough equations he’d worked out to address one of the thousands of riddles that need to be solved. This particular effort was an attempt (jargon alert) to optimize the incentive structure for proof-of-stake validation—that is, how best to get enough people and machines to participate in a computing operation essential to the functioning of the entire system. “We’re trying to do game theory here,” Zamfir said. The others pointed out what they thought might be flaws. “It doesn’t seem reasonable,” Zamfir said. “But the math works out.” This summarized much of what I’d encountered in crypto.
To his right sat Vitalik Buterin, Ethereum’s founder and semi-reluctant philosopher king. Buterin, who is twenty-four, occasionally glanced at Zamfir’s formulas but mostly looked into the middle distance with a melancholic empty stare, sometimes typing out messages and tweets on his phone with one finger. He was a quick study, and also he pretty much already knew what Zamfir had come up with, and to his thinking the work wasn’t quite there. “When the models are getting overcomplicated, it’s probably good to have more time to try to simplify them,” he told me later, with what I took to be generous understatement.
Buterin had been working, simultaneously, on another version of Casper. So he and Zamfir were both collaborating and competing with each other. There seemed to be no ego or bitterness—in their appraisal of each other’s work, in person, or on social media, where so much of the conversation takes place, in full view. Their assessments were Spockian, and cutting only to the Kirks among us.
They had first met before a conference in Toronto in 2014. Zamfir was amazed by Buterin, whom he called a “walking computer,” and he joined Ethereum as a researcher soon after. Now good friends who meet up mostly at conferences and workshops, they had greeted each other the day before in the hotel lobby with a fervent embrace, like summer campers back for another year, before quick-walking to a quiet corner to start in on the incentive-structure-for-proof-of-stake-validation talk. Whenever and wherever Buterin and Zamfir convene, people gather around—eavesdropping, hoping for scraps of insight. The two are used to this and pay little heed. There were no secrets, only problems and solutions, and the satisfaction that comes from proceeding from one toward the other.
The first time I heard the word “Ethereum” was in April, 2017. A hedge-fund manager, at a benefit in Manhattan, was telling me that he’d made more money buying and selling ether and other cryptocurrencies in the past year than he’d ever made at his old hedge fund. This was a significant claim, since the fund had made him a billionaire. He was using words I’d never heard before. He mentioned bitcoin, too, which I’d certainly heard a lot about but, like most people my age, didn’t really understand. I’d idly hoped I might be just old enough to make it to my deathbed without having to get up to speed.
As the year wore on, that dream faded. The surge in the price of bitcoin, and of other cryptocurrencies, which proliferated amid a craze for initial coin offerings (I.C.O.s), prompted a commensurate explosion in the number of stories and conversations about this new kind of money and, sometimes more to the point, about the blockchain technology behind it—this either revolutionary or needlessly laborious way of keeping track of transactions and data. It seemed as if language had been randomized. I started hearing those words—the ones I’d never heard before—an awful lot: “trustless,” “sharding,” “flippening.” Explaining blockchain became a genre unto itself.
The dizzying run-up in crypto prices in 2017 was followed, this year, by a long, lurching retreat that, as the summer gave way to fall, began to seem perilous. As with notorious stock-market and real-estate bubbles, innocents had been taken in and cleaned out. But both boom and bust reflected an ongoing argument over what cryptocurrencies and their technological underpinnings might be worth—which is to say, whether they are, as some like to ask, real. Is crypto the future or a fad? Golden ticket or Ponzi scheme? Amazon 2.0 or tulip mania? And what is it good for, anyway? It sure is neat, but for now it lacks its killer app, a use that might lead to mass adoption, as e-mail did for the Internet. “We need the hundred-dollar laptop, the iPod,” a blockchain apostle told me.
Now and then, legacy titans voiced their scorn. Jamie Dimon, the chief executive of J. P. Morgan, labelled crypto “a fraud”; Warren Buffett used the phrase “rat poison squared.” Legions of skeptics and technophobes, out of envy, ignorance, or wisdom, savored such pronouncements, while the true believers and the vertiginously invested mostly brushed it aside. They had faith that a new order was nigh. They pumped but did not dump.
Among a certain subset, it was both fashionable and integral to ignore the fluctuations in price. The idea was to build and shore up a new system—for everything from payments and banking to health care and identity—that was either a replacement for the old one, or at least an alternative to it, one that was borderless, independent of state control and of exploitation by Big Tech. “It’s definitely nice to try to eke out some completely parallel kind of world that’s totally separate from the existing one,” Buterin said. “It does interact with the rest of society, and the goal is definitely to help improve the mainstream world, but we’re on a different track.” Such an undertaking would, at best, take many years and likely span several economic and investment cycles. While the old armature rots, a new one rises alongside it, much as the new Tappan Zee Bridge, over the Hudson, gradually took shape next to the rusty old one it would one day replace. To Buterin, however, the benefits were already clear. “The cryptocurrency space has succeeded at making certain aspects of the international economy more open, when politics is moving in the exact opposite direction,” he said. “I do think that’s a meaningful contribution to the world.”
Buterin is a striking figure, tall and very lean, with long, fidgety fingers, sharp elfin features, and vivid blue eyes, which, on the rare occasions when he allows them to meet yours, convey a depth and warmth that you don’t expect, in light of the flat, robotic cadence and tone of his speech. People often joke about him being an alien, but they usually apologize for doing so, because there’s a gentleness about him, an air of tolerance and moderation, that works as a built-in rebuke to such unkind remarks. As we spoke, on the first afternoon of the Montreal conference (the crypto life is a never-ending enchainment of conferences, and is pretty much wall-to-wall dudes), he aligned some items in front of him: pens, Post-its, phone. He forgoes most social niceties and overt expressions of emotion but, when he finds questions or assertions agreeable, is generous with notes of encouragement: “Yep, yep, yep”; “Right, totally”; “Yes, yes, exactly.” Arguable remarks elicit a mechanical “Hmm.” He seems to anticipate your question before you even know quite what it is, but he forces himself to allow you to finish. He has a dry sense of humor.
He said, “I definitely don’t have the kind of single-minded C.E.O. personality that a lot of Silicon Valley V.C.s lionize—that thing of being ambitious and wanting to win at all costs, like, basically, Mark Zuckerberg.” He was dressed that day, as on the day before and the day after, in a gray turtleneck, black track pants, and laceless Adidas sneakers over turquoise socks. He often wears T-shirts with unicorns and rainbows. He likes to cite Lambos—as in Lamborghini, the cryptobro trophy ride of choice—as shorthand for the excessive trappings of wealth, which do not interest him. He’s about as indifferently rich as a man can be. Although he sold a quarter of his bitcoin and ether well before the prices began to soar last year, he is said to be worth somewhere in the vicinity of a hundred million dollars. (He recently gave away a couple of million dollars to a life-extension research project.) He has no assistants or entourage. He owns little and travels light. “Recently, I reduced my bag size from sixty litres to forty,” he said. “Forty is very tolerable. You can go on fifteen-kilometre walks with it.” The Adidas, he said, were his only pair of shoes. “Actually, I have another pair that’s in one of the many places I call home.” These are friends’ apartments, where he sometimes sleeps for a few nights at a stretch—in Toronto, San Francisco, Singapore, Shanghai, Taipei. He especially likes East Asia. He speaks fluent Mandarin.
After Montreal, he was headed to Berlin and then Switzerland. His home, really, is the Internet. At one point, I referred to an Ethereum outpost in San Francisco, which I’d read about, as a “base of operations,” and he rejected the term: “Home. Base of operations. The more you invent your own life style, the more you realize that the categories that have been invented are ultimately, at best, imperfect devices for understanding the world, and, at worst, fake.”
I’d been trying for months to talk to Buterin. In January, I reached out to his father, Dmitry, who reported back that Vitalik was not interested in an interview. “He is trying to focus his time on research,” Dmitry said. “He’s not too excited that the community assigns so much importance to him. He wants the community to be more resilient.” Dmitry Buterin, forty-six, is from Grozny, in Chechnya. He studied computer science in Moscow and then started a financial-software business, before emigrating to Canada, when Vitalik was six. Dmitry settled in Toronto, with Vitalik; Vitalik’s mother, a financial analyst, chose Edmonton. Vitalik, when he was three, got an old PC and began fiddling around with Excel. By ten or eleven, he was developing video games. “Vitalik was a very smart boy,” his father said. “It was not easy. His mind was always racing. It was hard for him to communicate. He hardly spoke until he was nine or ten. I was concerned, but at some point I realized it is what it is. I just gave him my love.”
He also gave Vitalik his first glimpse of Bitcoin. It was 2011, somewhat early, but Dmitry was an avowed anarcho-capitalist, a cynical child of Soviet and post-Soviet Russia. For many others like him, especially in those early days, the first encounter with Bitcoin was like a religious epiphany—powerful, life-altering, a glimpse of an entirely different and perhaps more agreeable way of ordering human affairs. “Bitcoin looks like money’s dream of itself,” the technology journalist Brian Patrick Eha wrote, in “How Money Got Free.”
“Before Bitcoin came along, I was happily playing World of Warcraft,” Vitalik told me. He had already been nursing some inchoate ideas about the risks and intrinsic unfairness of centralized systems and authority. He once told a journalist, “I saw everything to do with either government regulation or corporate control as just being plain evil. And I assumed that people in those institutions were kind of like Mr. Burns, sitting behind their desks saying, ‘Excellent. How can I screw a thousand people over this time?’ ” Bitcoin scratched this itch. But in many ways what drew him in was the elegance of the system, invented, it seemed, by a rogue outsider out of thin air. It suited a world view, a dream of a fluid, borderless, decentralized financial system beyond the reach of governments and banks, inclined as they inevitably are toward corruption and self-dealing, or at least toward distortions of incentive. Buterin said, “If you look at the people that were involved in the early stages of the Bitcoin space, their earlier pedigrees, if they had any pedigrees at all, were in open source—Linux, Mozilla, and cypherpunk mailing lists.” These were subversives and libertarians, ranging in political affinity from far left to weird right, as often as not without institutional or academic stature or access. “I found it immensely empowering that just a few thousand people like myself could re-create this fundamental social institution from nothing.”
In the eighties, cryptographers and computer scientists began trying to devise a foolproof form of digital money, and a way to execute transactions and contracts without the involvement (or rent-seeking) of third parties. It was the man, woman, or group of humans known as Satoshi Nakamoto who, with Bitcoin in 2008, solved the crux—the so-called double-spend problem. If you have ten dollars, you shouldn’t be able to pay ten dollars for one thing, then spend the same ten for another. This requires some mechanism for keeping track of what you have, whom you gave it to, and how much they now have. And that was the blockchain.
Definitions of blockchain are as various as the metaphors—bingo, Google Docs, a giant room of transparent safes—that people use to try to illustrate them. Broadly speaking, a blockchain is an evolving record of all transactions that is maintained, simultaneously and in common, by every computer in the network of that blockchain, be it Ethereum, Bitcoin, or Monero. Think, as some have suggested, of a dusty leather-bound ledger in a Dickensian counting house, a record of every transaction relevant to that practice. Except that every accountant in London, and in Calcutta, has the same ledger, and when one adds a line to his own the addition appears in all of them. Once a transaction is affirmed, it will—theoretically, anyway—be in the ledger forever, unalterable and unerasable.
Historically, records have been stored in one place—a temple, a courthouse, a server—and kept by whoever presided. If you distrust central authority, or are queasy about Google, this won’t do at all. With blockchains, the records, under a kind of cryptographic seal, are distributed to all and belong to no one. You can’t revise them, because everyone is watching, and because the software will reject it if you try. There is no Undo button. Each block is essentially a bundle of transactions, with a tracking notation, represented in a bit of cryptographic code known as a “hash,” of all the transactions in the past. Each new block in the chain contains all the information (or, really, via the hash, a secure reference to all the information) contained in the previous one, all the way back to the first one, the so-called genesis block.
There are other words that are sometimes included in the definition of blockchain, but they are slippery, and grounds for endless parsing, asterisking, and debate. One is “decentralized.” (Some blockchains are more decentralized than others.) Another is “immutable”—the idea that, in theory, the past record can’t be altered. (This is different from having your crypto stolen or hacked, when it’s stored in an online “wallet.” That happens all the time!) Then there’s “privacy.” The aspiration is for a digital coin to have the untraceability of cash. Because bitcoin was, at the outset, the dark Web’s go-to tender for the purchase of drugs, sex, weaponry, and such, many assumed that it was private. But it isn’t. Every transaction is there in the ledger for all to see. It is, fundamentally, anonymous (or pseudonymous, anyway), but there are many ways for that anonymity to be compromised.
The odds are high that someone, somewhere, has attempted to make an explanation like this one to you. The chain-splainer is a notorious date spoiler and cocktail-party pariah. Here he comes—you’re trapped. You should have known better than to ask about mining.
Mining is a reward system—compensation for helping to maintain and build a blockchain. The work of establishing and recording what’s legit takes machinery, memory, power, and time. Cryptocurrency blockchains require that a bunch of computers run software to affirm (or reject) transactions—it’s a kind of automated convocation. During this ritual, the computers in the network are competing, via brute guesswork, to be the first to get the answer to a really difficult math problem. The more computational power you have, the more guesses you can make, and the more likely you are to get the answer. The winner creates a new block and gets a reward, in, say, bitcoin—new bitcoin, which has not previously been in circulation. (Satoshi ordained that there be a finite number of bitcoin ever created—twenty-one million—so that no one could inflate away the value of existing bitcoin, as, say, the Federal Reserve does with dollars. Other cryptocurrencies, including ether, don’t necessarily have finite supplies.)
This system is known as Proof of Work. The problem-solving exercise is proof that the computers are doing the work. This approach has serious and, some would say, fatal, flaws. First, it requires a tremendous amount of electricity. This year, it is said, the Bitcoin network will use as much energy as the nation of Austria, and produce as much carbon dioxide as a million transatlantic flights. Mining rigs—computers designed specifically to do this work—are thirsty machines. Mining farms tend to sprout up where juice is cheap (typically, in proximity to hydropower projects with excess capacity to unload) and where temperatures are low (so you don’t have to burn even more electricity to keep the rigs cool). There are open-air warehouses in remote corners of sub-Arctic Canada, Russia, and China, with machines whirring away on the tundra, creating magic money, while the permafrost melts. Second, a small number of mining conglomerates, or pools—many of them Chinese—have wielded outsized influence over the network and the decisions that get made. Last month, one of the biggest of these, Bitmain, confirmed plans to go public.
The alternative, which Zamfir and Buterin were working on in Montreal, is called Proof of Stake. In this scenario, the holders of the currency in question become the validators, who typically take a small cut of every approved transaction. Theoretically, the more crypto you have, the more influence you have, so PoW partisans consider PoS to be plutocratic as well—a new gloss on the old problem of too much in the hands of too few.
In 2013, Buterin travelled to San Jose for a Bitcoin meet-up, and felt that he’d encountered like-minded people for the first time in his life—a movement worth devoting himself to. “The people that I had been searching for the whole time were actually all there,” Buterin told me. Zooko Wilcox, a cryptographer, recalled Buterin telling him, “This is the first technology I’ve ever loved that loves me back.” Buterin had been writing blog posts about it for five bitcoins per post. Together, he and Mihai Alisie, a Romanian blockchain entrepreneur who’d read his posts, founded Bitcoin Magazine. Buterin had a knack for explaining things—at least to an audience already primed to understand. But, as he travelled around the world to Bitcoin meet-ups, he began to think that the technology was limited, that attempts to jury-rig non-money uses for this digital-money platform was the computational equivalent of a Swiss Army knife. You basically had to devise hacks. He envisaged a one-blade-fits-all version, a blockchain platform that was broader and more adaptable to a wider array of uses and applications. The concept behind Bitcoin—a network of machines all over the world—seemed to be a building block upon which to construct a global computer capable of all kinds of activities.

The Prophets of Cryptocurrency Survey the Boom and Bust
The Prophets of Cryptocurrency Survey the Boom and Bust
Not long ago, I was in Montreal for a cryptocurrency conference. My hotel, on the top floor of a big building downtown, had a roof garden with a koi pond. One morning, as I had coffee and a bagel in this garden, I watched a pair of ducks feeding on a mound of pellets that someone had left for them at the pond’s edge. Every few seconds, they dipped their beaks to drink, and, in the process, spilled undigested pellets into the water. A few koi idled there, poking at the surface for the scraps. The longer I watched, the more I wondered if the ducks were deliberately feeding the fish. Was such a thing possible? I asked the breakfast attendant, a ruddy Quebecer. He smiled and said, “No, but it is what I tell the children.”
My mind had been marinating overnight—and for more than a year, really—in the abstrusities of cryptocurrencies and the blockchain technology on which they are built. Bitcoin and, subsequently, a proliferation of other cryptocurrencies had become an object of global fascination, amid prophecies of societal upheaval and reform, but mainly on the promise of instant wealth. A peer-to-peer money system that cut out banks and governments had made it possible, and fashionable, to get rich by sticking it to the Man.
Some of this stuff I understood; much of it I still did not. If you’re not, say, a computer scientist or a mathematician, the deeper you get into the esoterica of distributed ledgers, consensus algorithms, hash functions, zero-knowledge proofs, byzantine-fault-tolerance theory, and so on—the farther you travel from the familiar terrain of “the legacy world,” where, one blockchain futurist told me, pityingly, I live—the better the chance you have of bumping up against the limits of your intelligence. You grasp, instead, for metaphors.
Blockchain talk makes a whiteboard of the brain. You’re always erasing, starting over, as analogies present themselves. So, Montreal bagel in hand, I considered the ducks and the carp. Let the pellets be a cryptocurrency—koicoin, say. Would the ducks then be currency miners? Every altcoin—the catchall for cryptocurrencies other than bitcoin, the majority of which are eventually classified as shitcoin—has its own community of enthusiasts and kvetchers, so perhaps the koi were this one’s. The koicommunity. The breakfast attendant who had put out the pellets: he’d be our koicoin Satoshi—as in Satoshi Nakamoto, the pseudonymous and still unidentified creator of Bitcoin. Yes, the koicoin protocol was strong, and the incentives appeared to be well aligned, but the project didn’t really pass muster in terms of immutability, decentralization, and privacy. Koicoin was shitcoin.
A few hours later, I was at lunch in a conference room in another hotel, with a table of crypto wizards, a few of them among the most respected devs in the space. (Devs are developers, and even legacy worlders must surrender after a while and ditch the scare quotes around “the space,” when referring to the cryptosphere.) Four of these devs were researchers associated with Ethereum, the open-source blockchain platform. Ethereum is not itself a cryptocurrency; to operate on Ethereum, you have to use the cryptocurrency ether, which, like bitcoin, you can buy or sell. (Among cryptocurrencies, ether’s market capitalization is second only to bitcoin’s.) The devs were specimens of an itinerant coder élite, engaged, wherever they turn up and to the exclusion of pretty much everything else, in the ongoing construction of an alternate global financial and computational infrastructure: a new way of handling money or identity, a system they describe as a better, decentralized version of the World Wide Web—a Web 3.0—more in keeping with the Internet’s early utopian promise than with the invidious, monopolistic hellscape it has become. They want to seize back the tubes, and the data—our lives—from Facebook, Google, and the new oligarchs of Silicon Valley.
One of them, Vlad Zamfir, a twenty-eight-year-old Romanian-born mathematician who grew up in Ottawa and dropped out of the University of Guelph, was scribbling equations on an electronic tablet called a reMarkable pad. He narrated as he scrawled. The others at the table leaned in toward him, in a way that recalled Rembrandt’s “The Anatomy Lesson of Dr. Nicolaes Tulp.” To the two or three people at the table who were clearly incapable of following along, he said, earnestly, “Sorry to alienate you with my math.” Zamfir is the lead developer of one strand of Casper, an ongoing software upgrade designed to make Ethereum scale better and work more securely—an undertaking thought to be vital to its viability and survival. “It’s shitty technology,” Zamfir, whose Twitter bio reads “absurdist, troll,” told a journalist two years ago.
Zamfir was showing the others some rough equations he’d worked out to address one of the thousands of riddles that need to be solved. This particular effort was an attempt (jargon alert) to optimize the incentive structure for proof-of-stake validation—that is, how best to get enough people and machines to participate in a computing operation essential to the functioning of the entire system. “We’re trying to do game theory here,” Zamfir said. The others pointed out what they thought might be flaws. “It doesn’t seem reasonable,” Zamfir said. “But the math works out.” This summarized much of what I’d encountered in crypto.
To his right sat Vitalik Buterin, Ethereum’s founder and semi-reluctant philosopher king. Buterin, who is twenty-four, occasionally glanced at Zamfir’s formulas but mostly looked into the middle distance with a melancholic empty stare, sometimes typing out messages and tweets on his phone with one finger. He was a quick study, and also he pretty much already knew what Zamfir had come up with, and to his thinking the work wasn’t quite there. “When the models are getting overcomplicated, it’s probably good to have more time to try to simplify them,” he told me later, with what I took to be generous understatement.
Buterin had been working, simultaneously, on another version of Casper. So he and Zamfir were both collaborating and competing with each other. There seemed to be no ego or bitterness—in their appraisal of each other’s work, in person, or on social media, where so much of the conversation takes place, in full view. Their assessments were Spockian, and cutting only to the Kirks among us.
They had first met before a conference in Toronto in 2014. Zamfir was amazed by Buterin, whom he called a “walking computer,” and he joined Ethereum as a researcher soon after. Now good friends who meet up mostly at conferences and workshops, they had greeted each other the day before in the hotel lobby with a fervent embrace, like summer campers back for another year, before quick-walking to a quiet corner to start in on the incentive-structure-for-proof-of-stake-validation talk.

Buterin said, “If you look at the people that were involved in the early stages of the Bitcoin space, their earlier pedigrees, if they had any pedigrees at all, were in open source—Linux, Mozilla, and cypherpunk mailing lists.” These were subversives and libertarians, ranging in political affinity from far left to weird right, as often as not without institutional or academic stature or access. “I found it immensely empowering that just a few thousand people like myself could re-create this fundamental social institution from nothing.”
In the eighties, cryptographers and computer scientists began trying to devise a foolproof form of digital money, and a way to execute transactions and contracts without the involvement (or rent-seeking) of third parties. It was the man, woman, or group of humans known as Satoshi Nakamoto who, with Bitcoin in 2008, solved the crux—the so-called double-spend problem. If you have ten dollars, you shouldn’t be able to pay ten dollars for one thing, then spend the same ten for another. This requires some mechanism for keeping track of what you have, whom you gave it to, and how much they now have. And that was the blockchain.
Definitions of blockchain are as various as the metaphors—bingo, Google Docs, a giant room of transparent safes—that people use to try to illustrate them. Broadly speaking, a blockchain is an evolving record of all transactions that is maintained, simultaneously and in common, by every computer in the network of that blockchain, be it Ethereum, Bitcoin, or Monero. Think, as some have suggested, of a dusty leather-bound ledger in a Dickensian counting house, a record of every transaction relevant to that practice. Except that every accountant in London, and in Calcutta, has the same ledger, and when one adds a line to his own the addition appears in all of them. Once a transaction is affirmed, it will—theoretically, anyway—be in the ledger forever, unalterable and unerasable.
Historically, records have been stored in one place—a temple, a courthouse, a server—and kept by whoever presided. If you distrust central authority, or are queasy about Google, this won’t do at all. With blockchains, the records, under a kind of cryptographic seal, are distributed to all and belong to no one. You can’t revise them, because everyone is watching, and because the software will reject it if you try. There is no Undo button. Each block is essentially a bundle of transactions, with a tracking notation, represented in a bit of cryptographic code known as a “hash,” of all the transactions in the past. Each new block in the chain contains all the information (or, really, via the hash, a secure reference to all the information) contained in the previous one, all the way back to the first one, the so-called genesis block.
There are other words that are sometimes included in the definition of blockchain, but they are slippery, and grounds for endless parsing, asterisking, and debate. One is “decentralized.” (Some blockchains are more decentralized than others.) Another is “immutable”—the idea that, in theory, the past record can’t be altered. (This is different from having your crypto stolen or hacked, when it’s stored in an online “wallet.” That happens all the time!) Then there’s “privacy.” The aspiration is for a digital coin to have the untraceability of cash. Because bitcoin was, at the outset, the dark Web’s go-to tender for the purchase of drugs, sex, weaponry, and such, many assumed that it was private. But it isn’t. Every transaction is there in the ledger for all to see. It is, fundamentally, anonymous (or pseudonymous, anyway), but there are many ways for that anonymity to be compromised.
The odds are high that someone, somewhere, has attempted to make an explanation like this one to you. The chain-splainer is a notorious date spoiler and cocktail-party pariah. Here he comes—you’re trapped. You should have known better than to ask about mining.
Mining is a reward system—compensation for helping to maintain and build a blockchain. The work of establishing and recording what’s legit takes machinery, memory, power, and time. Cryptocurrency blockchains require that a bunch of computers run software to affirm (or reject) transactions—it’s a kind of automated convocation. During this ritual, the computers in the network are competing, via brute guesswork, to be the first to get the answer to a really difficult math problem. The more computational power you have, the more guesses you can make, and the more likely you are to get the answer. The winner creates a new block and gets a reward, in, say, bitcoin—new bitcoin, which has not previously been in circulation. (Satoshi ordained that there be a finite number of bitcoin ever created—twenty-one million—so that no one could inflate away the value of existing bitcoin, as, say, the Federal Reserve does with dollars. Other cryptocurrencies, including ether, don’t necessarily have finite supplies.)
This system is known as Proof of Work. The problem-solving exercise is proof that the computers are doing the work. This approach has serious and, some would say, fatal, flaws. First, it requires a tremendous amount of electricity. This year, it is said, the Bitcoin network will use as much energy as the nation of Austria, and produce as much carbon dioxide as a million transatlantic flights. Mining rigs—computers designed specifically to do this work—are thirsty machines. Mining farms tend to sprout up where juice is cheap (typically, in proximity to hydropower projects with excess capacity to unload) and where temperatures are low (so you don’t have to burn even more electricity to keep the rigs cool). There are open-air warehouses in remote corners of sub-Arctic Canada, Russia, and China, with machines whirring away on the tundra, creating magic money, while the permafrost melts. Second, a small number of mining conglomerates, or pools—many of them Chinese—have wielded outsized influence over the network and the decisions that get made. Last month, one of the biggest of these, Bitmain, confirmed plans to go public.
The alternative, which Zamfir and Buterin were working on in Montreal, is called Proof of Stake. In this scenario, the holders of the currency in question become the validators, who typically take a small cut of every approved transaction. Theoretically, the more crypto you have, the more influence you have, so PoW partisans consider PoS to be plutocratic as well—a new gloss on the old problem of too much in the hands of too few.
In 2013, Buterin travelled to San Jose for a Bitcoin meet-up, and felt that he’d encountered like-minded people for the first time in his life—a movement worth devoting himself to. “The people that I had been searching for the whole time were actually all there,” Buterin told me. Zooko Wilcox, a cryptographer, recalled Buterin telling him, “This is the first technology I’ve ever loved that loves me back.” Buterin had been writing blog posts about it for five bitcoins per post. Together, he and Mihai Alisie, a Romanian blockchain entrepreneur who’d read his posts, founded Bitcoin Magazine. Buterin had a knack for explaining things—at least to an audience already primed to understand. But, as he travelled around the world to Bitcoin meet-ups, he began to think that the technology was limited, that attempts to jury-rig non-money uses for this digital-money platform was the computational equivalent of a Swiss Army knife. You basically had to devise hacks. He envisaged a one-blade-fits-all version, a blockchain platform that was broader and more adaptable to a wider array of uses and applications. The concept behind Bitcoin—a network of machines all over the world—seemed to be a building block upon which to construct a global computer capable of all kinds of activities.

What is a 1t/h Chicken Feed Making Machine?
Chicken feed machine is suitable for small and medium-sized agricultural farms, such as raising rabbits, chickens, ducks, geese, fish, pigs, cattle, sheep, water, and other farmers. Chicken feed-making machines can also produce sinking fish feed, as well as powder, pellets, crushed materials, lump materials, etc.
Tumblr media
1. Raw material receiving and storage (cleaning) Impurities in the raw materials not only affect the growth of animals, but also easily cause blockage of pipelines and equipment, and even damage equipment (screens, ring molds, etc.). Screening, magnetic separation, and suction dust removal methods can be used.
2. Smash The purpose of crushing: increase the specific surface area of ​​the feed, improve the digestion and utilization of the feed by the animal; improve the quality of the subsequent processes such as ingredients, mixing, and pelleting, and improve the work efficiency of these processes.
3. Mixing process Ingredients are the process of feeding and metering various feed materials with specific ingredients in accordance with the requirements of the formula. Mixing is a process in which various material components are stirred and mixed after the feed product has been metered and formulated so that they are mixed and distributed evenly.
Tumblr media Tumblr media
5. Avoid automatic grading of feed ingredients and reduce environmental pollution. In the process of powder storage and transportation, due to the different volumes and masses of various powders, it is easy to produce a classification. After the pellets are made, there is no classification of feed ingredients, and the pellets are not easy to dust. During the feeding process, the pellets have much less pollution to air and moisture than powders.
6. Kill Salmonella in animal feed. Salmonella will remain in animal tissues after being ingested by animals. People who eat animals infected with this bacteria will suffer from Salmonella gastrointestinal problems. The method of steam high-temperature tempering and re-granulation can kill Salmonella in animal feed.
Henan Herm Machinery Co., Ltd was established in 2010 and has been devoted to the research and development of Feed Mill Machinery ever since. With more than 10 years of experience, Herm® has become a leading manufacturer and supplier of animal feed machines and complete animal feed production lines, cattle feed plants, poultry feed plants, animal feed pellet production lines, etc. It always endeavored to improve the quality of products and aims to meet the new requirements of the international market.

The Prophets of Cryptocurrency Survey the Boom and Bust
The Prophets of Cryptocurrency Survey the Boom and Bust
Not long ago, I was in Montreal for a cryptocurrency conference. My hotel, on the top floor of a big building downtown, had a roof garden with a koi pond. One morning, as I had coffee and a bagel in this garden, I watched a pair of ducks feeding on a mound of pellets that someone had left for them at the pond’s edge. Every few seconds, they dipped their beaks to drink, and, in the process, spilled undigested pellets into the water. A few koi idled there, poking at the surface for the scraps. The longer I watched, the more I wondered if the ducks were deliberately feeding the fish. Was such a thing possible? I asked the breakfast attendant, a ruddy Quebecer. He smiled and said, “No, but it is what I tell the children.”
My mind had been marinating overnight—and for more than a year, really—in the abstrusities of cryptocurrencies and the blockchain technology on which they are built. Bitcoin and, subsequently, a proliferation of other cryptocurrencies had become an object of global fascination, amid prophecies of societal upheaval and reform, but mainly on the promise of instant wealth. A peer-to-peer money system that cut out banks and governments had made it possible, and fashionable, to get rich by sticking it to the Man.
Some of this stuff I understood; much of it I still did not. If you’re not, say, a computer scientist or a mathematician, the deeper you get into the esoterica of distributed ledgers, consensus algorithms, hash functions, zero-knowledge proofs, byzantine-fault-tolerance theory, and so on—the farther you travel from the familiar terrain of “the legacy world,” where, one blockchain futurist told me, pityingly, I live—the better the chance you have of bumping up against the limits of your intelligence. You grasp, instead, for metaphors.
Blockchain talk makes a whiteboard of the brain. You’re always erasing, starting over, as analogies present themselves. So, Montreal bagel in hand, I considered the ducks and the carp. Let the pellets be a cryptocurrency—koicoin, say. Would the ducks then be currency miners? Every altcoin—the catchall for cryptocurrencies other than bitcoin, the majority of which are eventually classified as shitcoin—has its own community of enthusiasts and kvetchers, so perhaps the koi were this one’s. The koicommunity. The breakfast attendant who had put out the pellets: he’d be our koicoin Satoshi—as in Satoshi Nakamoto, the pseudonymous and still unidentified creator of Bitcoin. Yes, the koicoin protocol was strong, and the incentives appeared to be well aligned, but the project didn’t really pass muster in terms of immutability, decentralization, and privacy. Koicoin was shitcoin.
A few hours later, I was at lunch in a conference room in another hotel, with a table of crypto wizards, a few of them among the most respected devs in the space. (Devs are developers, and even legacy worlders must surrender after a while and ditch the scare quotes around “the space,” when referring to the cryptosphere.) Four of these devs were researchers associated with Ethereum, the open-source blockchain platform. Ethereum is not itself a cryptocurrency; to operate on Ethereum, you have to use the cryptocurrency ether, which, like bitcoin, you can buy or sell. (Among cryptocurrencies, ether’s market capitalization is second only to bitcoin’s.) The devs were specimens of an itinerant coder élite, engaged, wherever they turn up and to the exclusion of pretty much everything else, in the ongoing construction of an alternate global financial and computational infrastructure: a new way of handling money or identity, a system they describe as a better, decentralized version of the World Wide Web—a Web 3.0—more in keeping with the Internet’s early utopian promise than with the invidious, monopolistic hellscape it has become. They want to seize back the tubes, and the data—our lives—from Facebook, Google, and the new oligarchs of Silicon Valley.
One of them, Vlad Zamfir, a twenty-eight-year-old Romanian-born mathematician who grew up in Ottawa and dropped out of the University of Guelph, was scribbling equations on an electronic tablet called a reMarkable pad. He narrated as he scrawled. The others at the table leaned in toward him, in a way that recalled Rembrandt’s “The Anatomy Lesson of Dr. Nicolaes Tulp.” To the two or three people at the table who were clearly incapable of following along, he said, earnestly, “Sorry to alienate you with my math.” Zamfir is the lead developer of one strand of Casper, an ongoing software upgrade designed to make Ethereum scale better and work more securely—an undertaking thought to be vital to its viability and survival. “It’s shitty technology,” Zamfir, whose Twitter bio reads “absurdist, troll,” told a journalist two years ago.
Zamfir was showing the others some rough equations he’d worked out to address one of the thousands of riddles that need to be solved. This particular effort was an attempt (jargon alert) to optimize the incentive structure for proof-of-stake validation—that is, how best to get enough people and machines to participate in a computing operation essential to the functioning of the entire system. “We’re trying to do game theory here,” Zamfir said. The others pointed out what they thought might be flaws. “It doesn’t seem reasonable,” Zamfir said. “But the math works out.” This summarized much of what I’d encountered in crypto.
To his right sat Vitalik Buterin, Ethereum’s founder and semi-reluctant philosopher king. Buterin, who is twenty-four, occasionally glanced at Zamfir’s formulas but mostly looked into the middle distance with a melancholic empty stare, sometimes typing out messages and tweets on his phone with one finger. He was a quick study, and also he pretty much already knew what Zamfir had come up with, and to his thinking the work wasn’t quite there. “When the models are getting overcomplicated, it’s probably good to have more time to try to simplify them,” he told me later, with what I took to be generous understatement.
Buterin had been working, simultaneously, on another version of Casper. So he and Zamfir were both collaborating and competing with each other. There seemed to be no ego or bitterness—in their appraisal of each other’s work, in person, or on social media, where so much of the conversation takes place, in full view. Their assessments were Spockian, and cutting only to the Kirks among us.
They had first met before a conference in Toronto in 2014. Zamfir was amazed by Buterin, whom he called a “walking computer,” and he joined Ethereum as a researcher soon after. Now good friends who meet up mostly at conferences and workshops, they had greeted each other the day before in the hotel lobby with a fervent embrace, like summer campers back for another year, before quick-walking to a quiet corner to start in on the incentive-structure-for-proof-of-stake-validation talk. Whenever and wherever Buterin and Zamfir convene, people gather around—eavesdropping, hoping for scraps of insight. The two are used to this and pay little heed. There were no secrets, only problems and solutions, and the satisfaction that comes from proceeding from one toward the other.
The first time I heard the word “Ethereum” was in April, 2017. A hedge-fund manager, at a benefit in Manhattan, was telling me that he’d made more money buying and selling ether and other cryptocurrencies in the past year than he’d ever made at his old hedge fund. This was a significant claim, since the fund had made him a billionaire. He was using words I’d never heard before. He mentioned bitcoin, too, which I’d certainly heard a lot about but, like most people my age, didn’t really understand. I’d idly hoped I might be just old enough to make it to my deathbed without having to get up to speed.
As the year wore on, that dream faded. The surge in the price of bitcoin, and of other cryptocurrencies, which proliferated amid a craze for initial coin offerings (I.C.O.s), prompted a commensurate explosion in the number of stories and conversations about this new kind of money and, sometimes more to the point, about the blockchain technology behind it—this either revolutionary or needlessly laborious way of keeping track of transactions and data. It seemed as if language had been randomized. I started hearing those words—the ones I’d never heard before—an awful lot: “trustless,” “sharding,” “flippening.” Explaining blockchain became a genre unto itself.
The dizzying run-up in crypto prices in 2017 was followed, this year, by a long, lurching retreat that, as the summer gave way to fall, began to seem perilous. As with notorious stock-market and real-estate bubbles, innocents had been taken in and cleaned out. But both boom and bust reflected an ongoing argument over what cryptocurrencies and their technological underpinnings might be worth—which is to say, whether they are, as some like to ask, real. Is crypto the future or a fad? Golden ticket or Ponzi scheme? Amazon 2.0 or tulip mania? And what is it good for, anyway? It sure is neat, but for now it lacks its killer app, a use that might lead to mass adoption, as e-mail did for the Internet. “We need the hundred-dollar laptop, the iPod,” a blockchain apostle told me.
Now and then, legacy titans voiced their scorn. Jamie Dimon, the chief executive of J. P. Morgan, labelled crypto “a fraud”; Warren Buffett used the phrase “rat poison squared.” Legions of skeptics and technophobes, out of envy, ignorance, or wisdom, savored such pronouncements, while the true believers and the vertiginously invested mostly brushed it aside. They had faith that a new order was nigh. They pumped but did not dump.
Among a certain subset, it was both fashionable and integral to ignore the fluctuations in price. The idea was to build and shore up a new system—for everything from payments and banking to health care and identity—that was either a replacement for the old one, or at least an alternative to it, one that was borderless, independent of state control and of exploitation by Big Tech. “It’s definitely nice to try to eke out some completely parallel kind of world that’s totally separate from the existing one,” Buterin said. “It does interact with the rest of society, and the goal is definitely to help improve the mainstream world, but we’re on a different track.” Such an undertaking would, at best, take many years and likely span several economic and investment cycles. While the old armature rots, a new one rises alongside it, much as the new Tappan Zee Bridge, over the Hudson, gradually took shape next to the rusty old one it would one day replace. To Buterin, however, the benefits were already clear. “The cryptocurrency space has succeeded at making certain aspects of the international economy more open, when politics is moving in the exact opposite direction,” he said. “I do think that’s a meaningful contribution to the world.”
Buterin is a striking figure, tall and very lean, with long, fidgety fingers, sharp elfin features, and vivid blue eyes, which, on the rare occasions when he allows them to meet yours, convey a depth and warmth that you don’t expect, in light of the flat, robotic cadence and tone of his speech. People often joke about him being an alien, but they usually apologize for doing so, because there’s a gentleness about him, an air of tolerance and moderation, that works as a built-in rebuke to such unkind remarks. As we spoke, on the first afternoon of the Montreal conference (the crypto life is a never-ending enchainment of conferences, and is pretty much wall-to-wall dudes), he aligned some items in front of him: pens, Post-its, phone. He forgoes most social niceties and overt expressions of emotion but, when he finds questions or assertions agreeable, is generous with notes of encouragement: “Yep, yep, yep”; “Right, totally”; “Yes, yes, exactly.” Arguable remarks elicit a mechanical “Hmm.” He seems to anticipate your question before you even know quite what it is, but he forces himself to allow you to finish. He has a dry sense of humor.
He said, “I definitely don’t have the kind of single-minded C.E.O. personality that a lot of Silicon Valley V.C.s lionize—that thing of being ambitious and wanting to win at all costs, like, basically, Mark Zuckerberg.” He was dressed that day, as on the day before and the day after, in a gray turtleneck, black track pants, and laceless Adidas sneakers over turquoise socks. He often wears T-shirts with unicorns and rainbows. He likes to cite Lambos—as in Lamborghini, the cryptobro trophy ride of choice—as shorthand for the excessive trappings of wealth, which do not interest him. He’s about as indifferently rich as a man can be. Although he sold a quarter of his bitcoin and ether well before the prices began to soar last year, he is said to be worth somewhere in the vicinity of a hundred million dollars. (He recently gave away a couple of million dollars to a life-extension research project.) He has no assistants or entourage. He owns little and travels light. “Recently, I reduced my bag size from sixty litres to forty,” he said. “Forty is very tolerable. You can go on fifteen-kilometre walks with it.” The Adidas, he said, were his only pair of shoes. “Actually, I have another pair that’s in one of the many places I call home.” These are friends’ apartments, where he sometimes sleeps for a few nights at a stretch—in Toronto, San Francisco, Singapore, Shanghai, Taipei. He especially likes East Asia. He speaks fluent Mandarin.
After Montreal, he was headed to Berlin and then Switzerland. His home, really, is the Internet. At one point, I referred to an Ethereum outpost in San Francisco, which I’d read about, as a “base of operations,” and he rejected the term: “Home. Base of operations. The more you invent your own life style, the more you realize that the categories that have been invented are ultimately, at best, imperfect devices for understanding the world, and, at worst, fake.”
I’d been trying for months to talk to Buterin. In January, I reached out to his father, Dmitry, who reported back that Vitalik was not interested in an interview. “He is trying to focus his time on research,” Dmitry said. “He’s not too excited that the community assigns so much importance to him. He wants the community to be more resilient.” Dmitry Buterin, forty-six, is from Grozny, in Chechnya. He studied computer science in Moscow and then started a financial-software business, before emigrating to Canada, when Vitalik was six. Dmitry settled in Toronto, with Vitalik; Vitalik’s mother, a financial analyst, chose Edmonton. Vitalik, when he was three, got an old PC and began fiddling around with Excel. By ten or eleven, he was developing video games. “Vitalik was a very smart boy,” his father said. “It was not easy. His mind was always racing. It was hard for him to communicate. He hardly spoke until he was nine or ten. I was concerned, but at some point I realized it is what it is. I just gave him my love.”
He also gave Vitalik his first glimpse of Bitcoin. It was 2011, somewhat early, but Dmitry was an avowed anarcho-capitalist, a cynical child of Soviet and post-Soviet Russia. For many others like him, especially in those early days, the first encounter with Bitcoin was like a religious epiphany—powerful, life-altering, a glimpse of an entirely different and perhaps more agreeable way of ordering human affairs. “Bitcoin looks like money’s dream of itself,” the technology journalist Brian Patrick Eha wrote, in “How Money Got Free.”
“Before Bitcoin came along, I was happily playing World of Warcraft,” Vitalik told me. He had already been nursing some inchoate ideas about the risks and intrinsic unfairness of centralized systems and authority. He once told a journalist, “I saw everything to do with either government regulation or corporate control as just being plain evil. And I assumed that people in those institutions were kind of like Mr. Burns, sitting behind their desks saying, ‘Excellent. How can I screw a thousand people over this time?’ ” Bitcoin scratched this itch. But in many ways what drew him in was the elegance of the system, invented, it seemed, by a rogue outsider out of thin air. It suited a world view, a dream of a fluid, borderless, decentralized financial system beyond the reach of governments and banks, inclined as they inevitably are toward corruption and self-dealing, or at least toward distortions of incentive. Buterin said, “If you look at the people that were involved in the early stages of the Bitcoin space, their earlier pedigrees, if they had any pedigrees at all, were in open source—Linux, Mozilla, and cypherpunk mailing lists.” These were subversives and libertarians, ranging in political affinity from far left to weird right, as often as not without institutional or academic stature or access. “I found it immensely empowering that just a few thousand people like myself could re-create this fundamental social institution from nothing.”
In the eighties, cryptographers and computer scientists began trying to devise a foolproof form of digital money, and a way to execute transactions and contracts without the involvement (or rent-seeking) of third parties. It was the man, woman, or group of humans known as Satoshi Nakamoto who, with Bitcoin in 2008, solved the crux—the so-called double-spend problem.

Broadly speaking, a blockchain is an evolving record of all transactions that is maintained, simultaneously and in common, by every computer in the network of that blockchain, be it Ethereum, Bitcoin, or Monero. Think, as some have suggested, of a dusty leather-bound ledger in a Dickensian counting house, a record of every transaction relevant to that practice. Except that every accountant in London, and in Calcutta, has the same ledger, and when one adds a line to his own the addition appears in all of them.

The Prophets of Cryptocurrency Survey the Boom and Bust
The Prophets of Cryptocurrency Survey the Boom and Bust
Not long ago, I was in Montreal for a cryptocurrency conference. My hotel, on the top floor of a big building downtown, had a roof garden with a koi pond. One morning, as I had coffee and a bagel in this garden, I watched a pair of ducks feeding on a mound of pellets that someone had left for them at the pond’s edge. Every few seconds, they dipped their beaks to drink, and, in the process, spilled undigested pellets into the water. A few koi idled there, poking at the surface for the scraps. The longer I watched, the more I wondered if the ducks were deliberately feeding the fish. Was such a thing possible? I asked the breakfast attendant, a ruddy Quebecer. He smiled and said, “No, but it is what I tell the children.”
My mind had been marinating overnight—and for more than a year, really—in the abstrusities of cryptocurrencies and the blockchain technology on which they are built. Bitcoin and, subsequently, a proliferation of other cryptocurrencies had become an object of global fascination, amid prophecies of societal upheaval and reform, but mainly on the promise of instant wealth. A peer-to-peer money system that cut out banks and governments had made it possible, and fashionable, to get rich by sticking it to the Man.
Some of this stuff I understood; much of it I still did not. If you’re not, say, a computer scientist or a mathematician, the deeper you get into the esoterica of distributed ledgers, consensus algorithms, hash functions, zero-knowledge proofs, byzantine-fault-tolerance theory, and so on—the farther you travel from the familiar terrain of “the legacy world,” where, one blockchain futurist told me, pityingly, I live—the better the chance you have of bumping up against the limits of your intelligence. You grasp, instead, for metaphors.
Blockchain talk makes a whiteboard of the brain. You’re always erasing, starting over, as analogies present themselves. So, Montreal bagel in hand, I considered the ducks and the carp. Let the pellets be a cryptocurrency—koicoin, say. Would the ducks then be currency miners? Every altcoin—the catchall for cryptocurrencies other than bitcoin, the majority of which are eventually classified as shitcoin—has its own community of enthusiasts and kvetchers, so perhaps the koi were this one’s. The koicommunity. The breakfast attendant who had put out the pellets: he’d be our koicoin Satoshi—as in Satoshi Nakamoto, the pseudonymous and still unidentified creator of Bitcoin. Yes, the koicoin protocol was strong, and the incentives appeared to be well aligned, but the project didn’t really pass muster in terms of immutability, decentralization, and privacy. Koicoin was shitcoin.
A few hours later, I was at lunch in a conference room in another hotel, with a table of crypto wizards, a few of them among the most respected devs in the space. (Devs are developers, and even legacy worlders must surrender after a while and ditch the scare quotes around “the space,” when referring to the cryptosphere.) Four of these devs were researchers associated with Ethereum, the open-source blockchain platform. Ethereum is not itself a cryptocurrency; to operate on Ethereum, you have to use the cryptocurrency ether, which, like bitcoin, you can buy or sell. (Among cryptocurrencies, ether’s market capitalization is second only to bitcoin’s.) The devs were specimens of an itinerant coder élite, engaged, wherever they turn up and to the exclusion of pretty much everything else, in the ongoing construction of an alternate global financial and computational infrastructure: a new way of handling money or identity, a system they describe as a better, decentralized version of the World Wide Web—a Web 3.0—more in keeping with the Internet’s early utopian promise than with the invidious, monopolistic hellscape it has become. They want to seize back the tubes, and the data—our lives—from Facebook, Google, and the new oligarchs of Silicon Valley.
One of them, Vlad Zamfir, a twenty-eight-year-old Romanian-born mathematician who grew up in Ottawa and dropped out of the University of Guelph, was scribbling equations on an electronic tablet called a reMarkable pad. He narrated as he scrawled. The others at the table leaned in toward him, in a way that recalled Rembrandt’s “The Anatomy Lesson of Dr. Nicolaes Tulp.” To the two or three people at the table who were clearly incapable of following along, he said, earnestly, “Sorry to alienate you with my math.” Zamfir is the lead developer of one strand of Casper, an ongoing software upgrade designed to make Ethereum scale better and work more securely—an undertaking thought to be vital to its viability and survival. “It’s shitty technology,” Zamfir, whose Twitter bio reads “absurdist, troll,” told a journalist two years ago.
Zamfir was showing the others some rough equations he’d worked out to address one of the thousands of riddles that need to be solved. This particular effort was an attempt (jargon alert) to optimize the incentive structure for proof-of-stake validation—that is, how best to get enough people and machines to participate in a computing operation essential to the functioning of the entire system. “We’re trying to do game theory here,” Zamfir said. The others pointed out what they thought might be flaws. “It doesn’t seem reasonable,” Zamfir said. “But the math works out.” This summarized much of what I’d encountered in crypto.
To his right sat Vitalik Buterin, Ethereum’s founder and semi-reluctant philosopher king. Buterin, who is twenty-four, occasionally glanced at Zamfir’s formulas but mostly looked into the middle distance with a melancholic empty stare, sometimes typing out messages and tweets on his phone with one finger. He was a quick study, and also he pretty much already knew what Zamfir had come up with, and to his thinking the work wasn’t quite there. “When the models are getting overcomplicated, it’s probably good to have more time to try to simplify them,” he told me later, with what I took to be generous understatement.
Buterin had been working, simultaneously, on another version of Casper. So he and Zamfir were both collaborating and competing with each other. There seemed to be no ego or bitterness—in their appraisal of each other’s work, in person, or on social media, where so much of the conversation takes place, in full view. Their assessments were Spockian, and cutting only to the Kirks among us.
They had first met before a conference in Toronto in 2014. Zamfir was amazed by Buterin, whom he called a “walking computer,” and he joined Ethereum as a researcher soon after. Now good friends who meet up mostly at conferences and workshops, they had greeted each other the day before in the hotel lobby with a fervent embrace, like summer campers back for another year, before quick-walking to a quiet corner to start in on the incentive-structure-for-proof-of-stake-validation talk. Whenever and wherever Buterin and Zamfir convene, people gather around—eavesdropping, hoping for scraps of insight. The two are used to this and pay little heed. There were no secrets, only problems and solutions, and the satisfaction that comes from proceeding from one toward the other.
The first time I heard the word “Ethereum” was in April, 2017. A hedge-fund manager, at a benefit in Manhattan, was telling me that he’d made more money buying and selling ether and other cryptocurrencies in the past year than he’d ever made at his old hedge fund. This was a significant claim, since the fund had made him a billionaire. He was using words I’d never heard before. He mentioned bitcoin, too, which I’d certainly heard a lot about but, like most people my age, didn’t really understand. I’d idly hoped I might be just old enough to make it to my deathbed without having to get up to speed.
As the year wore on, that dream faded. The surge in the price of bitcoin, and of other cryptocurrencies, which proliferated amid a craze for initial coin offerings (I.C.O.s), prompted a commensurate explosion in the number of stories and conversations about this new kind of money and, sometimes more to the point, about the blockchain technology behind it—this either revolutionary or needlessly laborious way of keeping track of transactions and data. It seemed as if language had been randomized. I started hearing those words—the ones I’d never heard before—an awful lot: “trustless,” “sharding,” “flippening.” Explaining blockchain became a genre unto itself.
The dizzying run-up in crypto prices in 2017 was followed, this year, by a long, lurching retreat that, as the summer gave way to fall, began to seem perilous. As with notorious stock-market and real-estate bubbles, innocents had been taken in and cleaned out. But both boom and bust reflected an ongoing argument over what cryptocurrencies and their technological underpinnings might be worth—which is to say, whether they are, as some like to ask, real. Is crypto the future or a fad? Golden ticket or Ponzi scheme? Amazon 2.0 or tulip mania? And what is it good for, anyway? It sure is neat, but for now it lacks its killer app, a use that might lead to mass adoption, as e-mail did for the Internet. “We need the hundred-dollar laptop, the iPod,” a blockchain apostle told me.
Now and then, legacy titans voiced their scorn. Jamie Dimon, the chief executive of J. P. Morgan, labelled crypto “a fraud”; Warren Buffett used the phrase “rat poison squared.” Legions of skeptics and technophobes, out of envy, ignorance, or wisdom, savored such pronouncements, while the true believers and the vertiginously invested mostly brushed it aside. They had faith that a new order was nigh. They pumped but did not dump.
Among a certain subset, it was both fashionable and integral to ignore the fluctuations in price. The idea was to build and shore up a new system—for everything from payments and banking to health care and identity—that was either a replacement for the old one, or at least an alternative to it, one that was borderless, independent of state control and of exploitation by Big Tech. “It’s definitely nice to try to eke out some completely parallel kind of world that’s totally separate from the existing one,” Buterin said. “It does interact with the rest of society, and the goal is definitely to help improve the mainstream world, but we’re on a different track.” Such an undertaking would, at best, take many years and likely span several economic and investment cycles. While the old armature rots, a new one rises alongside it, much as the new Tappan Zee Bridge, over the Hudson, gradually took shape next to the rusty old one it would one day replace. To Buterin, however, the benefits were already clear. “The cryptocurrency space has succeeded at making certain aspects of the international economy more open, when politics is moving in the exact opposite direction,” he said. “I do think that’s a meaningful contribution to the world.”
Buterin is a striking figure, tall and very lean, with long, fidgety fingers, sharp elfin features, and vivid blue eyes, which, on the rare occasions when he allows them to meet yours, convey a depth and warmth that you don’t expect, in light of the flat, robotic cadence and tone of his speech. People often joke about him being an alien, but they usually apologize for doing so, because there’s a gentleness about him, an air of tolerance and moderation, that works as a built-in rebuke to such unkind remarks. As we spoke, on the first afternoon of the Montreal conference (the crypto life is a never-ending enchainment of conferences, and is pretty much wall-to-wall dudes), he aligned some items in front of him: pens, Post-its, phone. He forgoes most social niceties and overt expressions of emotion but, when he finds questions or assertions agreeable, is generous with notes of encouragement: “Yep, yep, yep”; “Right, totally”; “Yes, yes, exactly.” Arguable remarks elicit a mechanical “Hmm.” He seems to anticipate your question before you even know quite what it is, but he forces himself to allow you to finish. He has a dry sense of humor.
He said, “I definitely don’t have the kind of single-minded C.E.O. personality that a lot of Silicon Valley V.C.s lionize—that thing of being ambitious and wanting to win at all costs, like, basically, Mark Zuckerberg.” He was dressed that day, as on the day before and the day after, in a gray turtleneck, black track pants, and laceless Adidas sneakers over turquoise socks. He often wears T-shirts with unicorns and rainbows. He likes to cite Lambos—as in Lamborghini, the cryptobro trophy ride of choice—as shorthand for the excessive trappings of wealth, which do not interest him. He’s about as indifferently rich as a man can be. Although he sold a quarter of his bitcoin and ether well before the prices began to soar last year, he is said to be worth somewhere in the vicinity of a hundred million dollars. (He recently gave away a couple of million dollars to a life-extension research project.) He has no assistants or entourage. He owns little and travels light. “Recently, I reduced my bag size from sixty litres to forty,” he said. “Forty is very tolerable. You can go on fifteen-kilometre walks with it.” The Adidas, he said, were his only pair of shoes. “Actually, I have another pair that’s in one of the many places I call home.” These are friends’ apartments, where he sometimes sleeps for a few nights at a stretch—in Toronto, San Francisco, Singapore, Shanghai, Taipei. He especially likes East Asia. He speaks fluent Mandarin.
After Montreal, he was headed to Berlin and then Switzerland. His home, really, is the Internet. At one point, I referred to an Ethereum outpost in San Francisco, which I’d read about, as a “base of operations,” and he rejected the term: “Home. Base of operations. The more you invent your own life style, the more you realize that the categories that have been invented are ultimately, at best, imperfect devices for understanding the world, and, at worst, fake.”
I’d been trying for months to talk to Buterin. In January, I reached out to his father, Dmitry, who reported back that Vitalik was not interested in an interview. “He is trying to focus his time on research,” Dmitry said. “He’s not too excited that the community assigns so much importance to him. He wants the community to be more resilient.” Dmitry Buterin, forty-six, is from Grozny, in Chechnya. He studied computer science in Moscow and then started a financial-software business, before emigrating to Canada, when Vitalik was six. Dmitry settled in Toronto, with Vitalik; Vitalik’s mother, a financial analyst, chose Edmonton. Vitalik, when he was three, got an old PC and began fiddling around with Excel. By ten or eleven, he was developing video games. “Vitalik was a very smart boy,” his father said. “It was not easy. His mind was always racing. It was hard for him to communicate. He hardly spoke until he was nine or ten. I was concerned, but at some point I realized it is what it is. I just gave him my love.”
He also gave Vitalik his first glimpse of Bitcoin. It was 2011, somewhat early, but Dmitry was an avowed anarcho-capitalist, a cynical child of Soviet and post-Soviet Russia. For many others like him, especially in those early days, the first encounter with Bitcoin was like a religious epiphany—powerful, life-altering, a glimpse of an entirely different and perhaps more agreeable way of ordering human affairs. “Bitcoin looks like money’s dream of itself,” the technology journalist Brian Patrick Eha wrote, in “How Money Got Free.”
“Before Bitcoin came along, I was happily playing World of Warcraft,” Vitalik told me. He had already been nursing some inchoate ideas about the risks and intrinsic unfairness of centralized systems and authority. He once told a journalist, “I saw everything to do with either government regulation or corporate control as just being plain evil. And I assumed that people in those institutions were kind of like Mr. Burns, sitting behind their desks saying, ‘Excellent. How can I screw a thousand people over this time?’ ” Bitcoin scratched this itch. But in many ways what drew him in was the elegance of the system, invented, it seemed, by a rogue outsider out of thin air. It suited a world view, a dream of a fluid, borderless, decentralized financial system beyond the reach of governments and banks, inclined as they inevitably are toward corruption and self-dealing, or at least toward distortions of incentive. Buterin said, “If you look at the people that were involved in the early stages of the Bitcoin space, their earlier pedigrees, if they had any pedigrees at all, were in open source—Linux, Mozilla, and cypherpunk mailing lists.” These were subversives and libertarians, ranging in political affinity from far left to weird right, as often as not without institutional or academic stature or access. “I found it immensely empowering that just a few thousand people like myself could re-create this fundamental social institution from nothing.”
In the eighties, cryptographers and computer scientists began trying to devise a foolproof form of digital money, and a way to execute transactions and contracts without the involvement (or rent-seeking) of third parties. It was the man, woman, or group of humans known as Satoshi Nakamoto who, with Bitcoin in 2008, solved the crux—the so-called double-spend problem. If you have ten dollars, you shouldn’t be able to pay ten dollars for one thing, then spend the same ten for another. This requires some mechanism for keeping track of what you have, whom you gave it to, and how much they now have. And that was the blockchain.
Definitions of blockchain are as various as the metaphors—bingo, Google Docs, a giant room of transparent safes—that people use to try to illustrate them. Broadly speaking, a blockchain is an evolving record of all transactions that is maintained, simultaneously and in common, by every computer in the network of that blockchain, be it Ethereum, Bitcoin, or Monero. Think, as some have suggested, of a dusty leather-bound ledger in a Dickensian counting house, a record of every transaction relevant to that practice. Except that every accountant in London, and in Calcutta, has the same ledger, and when one adds a line to his own the addition appears in all of them. Once a transaction is affirmed, it will—theoretically, anyway—be in the ledger forever, unalterable and unerasable.
Historically, records have been stored in one place—a temple, a courthouse, a server—and kept by whoever presided. If you distrust central authority, or are queasy about Google, this won’t do at all. With blockchains, the records, under a kind of cryptographic seal, are distributed to all and belong to no one. You can’t revise them, because everyone is watching, and because the software will reject it if you try. There is no Undo button. Each block is essentially a bundle of transactions, with a tracking notation, represented in a bit of cryptographic code known as a “hash,” of all the transactions in the past. Each new block in the chain contains all the information (or, really, via the hash, a secure reference to all the information) contained in the previous one, all the way back to the first one, the so-called genesis block.
There are other words that are sometimes included in the definition of blockchain, but they are slippery, and grounds for endless parsing, asterisking, and debate. One is “decentralized.” (Some blockchains are more decentralized than others.) Another is “immutable”—the idea that, in theory, the past record can’t be altered. (This is different from having your crypto stolen or hacked, when it’s stored in an online “wallet.” That happens all the time!) Then there’s “privacy.” The aspiration is for a digital coin to have the untraceability of cash. Because bitcoin was, at the outset, the dark Web’s go-to tender for the purchase of drugs, sex, weaponry, and such, many assumed that it was private. But it isn’t. Every transaction is there in the ledger for all to see. It is, fundamentally, anonymous (or pseudonymous, anyway), but there are many ways for that anonymity to be compromised.
The odds are high that someone, somewhere, has attempted to make an explanation like this one to you. The chain-splainer is a notorious date spoiler and cocktail-party pariah. Here he comes—you’re trapped. You should have known better than to ask about mining.
Mining is a reward system—compensation for helping to maintain and build a blockchain. The work of establishing and recording what’s legit takes machinery, memory, power, and time. Cryptocurrency blockchains require that a bunch of computers run software to affirm (or reject) transactions—it’s a kind of automated convocation. During this ritual, the computers in the network are competing, via brute guesswork, to be the first to get the answer to a really difficult math problem. The more computational power you have, the more guesses you can make, and the more likely you are to get the answer. The winner creates a new block and gets a reward, in, say, bitcoin—new bitcoin, which has not previously been in circulation. (Satoshi ordained that there be a finite number of bitcoin ever created—twenty-one million—so that no one could inflate away the value of existing bitcoin, as, say, the Federal Reserve does with dollars. Other cryptocurrencies, including ether, don’t necessarily have finite supplies.)
This system is known as Proof of Work. The problem-solving exercise is proof that the computers are doing the work. This approach has serious and, some would say, fatal, flaws. First, it requires a tremendous amount of electricity. This year, it is said, the Bitcoin network will use as much energy as the nation of Austria, and produce as much carbon dioxide as a million transatlantic flights. Mining rigs—computers designed specifically to do this work—are thirsty machines. Mining farms tend to sprout up where juice is cheap (typically, in proximity to hydropower projects with excess capacity to unload) and where temperatures are low (so you don’t have to burn even more electricity to keep the rigs cool). There are open-air warehouses in remote corners of sub-Arctic Canada, Russia, and China, with machines whirring away on the tundra, creating magic money, while the permafrost melts. Second, a small number of mining conglomerates, or pools—many of them Chinese—have wielded outsized influence over the network and the decisions that get made. Last month, one of the biggest of these, Bitmain, confirmed plans to go public.
The alternative, which Zamfir and Buterin were working on in Montreal, is called Proof of Stake. In this scenario, the holders of the currency in question become the validators, who typically take a small cut of every approved transaction. Theoretically, the more crypto you have, the more influence you have, so PoW partisans consider PoS to be plutocratic as well—a new gloss on the old problem of too much in the hands of too few.
In 2013, Buterin travelled to San Jose for a Bitcoin meet-up, and felt that he’d encountered like-minded people for the first time in his life—a movement worth devoting himself to. “The people that I had been searching for the whole time were actually all there,” Buterin told me. Zooko Wilcox, a cryptographer, recalled Buterin telling him, “This is the first technology I’ve ever loved that loves me back.” Buterin had been writing blog posts about it for five bitcoins per post. Together, he and Mihai Alisie, a Romanian blockchain entrepreneur who’d read his posts, founded Bitcoin Magazine. Buterin had a knack for explaining things—at least to an audience already primed to understand. But, as he travelled around the world to Bitcoin meet-ups, he began to think that the technology was limited, that attempts to jury-rig non-money uses for this digital-money platform was the computational equivalent of a Swiss Army knife. You basically had to devise hacks. He envisaged a one-blade-fits-all version, a blockchain platform that was broader and more adaptable to a wider array of uses and applications. The concept behind Bitcoin—a network of machines all over the world—seemed to be a building block upon which to construct a global computer capable of all kinds of activities.

Farmed Fish Are Depleting Oceans of Wild Fish
It's estimated that within the next 10 years, farm-raised fish will make up the majority of fish consumed by humans. There are already 100 species being farmed,1 and while aquaculture, as it's technically known, may sound like a sustainable alternative to catching wild fish, it poses many of the same problems plaguing industrial land-based livestock operations, or concentrated animal feeding operations (CAFOs).
Among these is the need for a concentrated source of food. On land, this often comes in the form of genetically engineered corn and soy, but farmed fish are sustained via a diet of other fish, known as fishmeal. Aquaculture is a $160 billion industry,2 and as one of the fastest-growing sectors in the food production industry, its appetite for fishmeal is immense.
About 25 percent of wild-caught fish — amounting to about 20 million tons of seafood — are used to make fishmeal that's fed to farmed fish,3 and stocks of wild fish may be dwindling as a result.
Sardinella Stocks Dwindling as Demand for Fishmeal Increases
In West Africa, sardinella is one of the most important fish species for both food security and job creation. It's also one prized for the production of fishmeal powder. In Mauritania, a country in Northwest Africa, 770,000 tons of sardinella are caught annually, up from 440,000 tons just a few years ago, according to a 2015 report funded by the European Union.4
Looking to cash in on the growing fishmeal demand, Chinese investors have built factories dedicated to exploiting the seemingly copious amounts of fish in Mauritania, Senegal and Gambia.
Yet, according to Abdou Karim Sall, president of an association of small-scale fishermen in Senegal, who spoke to Reuters, "In four or five years, there won't be any fish stocks left; the factories will close, and the foreigners will leave ... We'll be left here without any fish."5
In a Reuters investigation, it's revealed that aquaculture is increasingly taking sardinella away from the local people who depend on it for their survival. Reuters reported:6
"Sardinella migrate across a 1,000-mile zone shared by Mauritania, Senegal and Gambia. Officials from each country insist that they want to manage their fish sustainably and develop the kind of processing, freezing and export industries that could create thousands of jobs.
But with no effective regional management system yet in place, this goal may not be compatible with installing ever-more grinding machines for the benefit of fish farms producing food for Asia, Europe and North America."
Fishmeal Factories Encourage Local Fish Fleets to Exploit Fish Stocks
According to the Coalition for Fair Fisheries Arrangements (CFFA), which promotes the livelihoods and food security of costal fishing communities, catches of sardinella in West Africa continue to decline, including in Mauritania, where only 172,000 tons were caught in 2017, down 41 percent from the 292,000 tons caught in 2016.7
Prior to the introduction of the fishmeal industry, the sardinella catch was limited naturally by how much the local market would bear. This natural limit has been removed now that fishmeal factories will buy as much fish as the fishing fleets will bring in. Marine scientist Patrice Brehmer told Reuters, "We could face a catastrophic situation."8 CFFA agrees, noting:9
"Whereas the effort by artisanal fleets in earlier years was restricted by the demand from the human consumption market, this restriction no longer exists at the moment. The fishmeal plants can absorb large quantities of fish, which stimulates artisanal fishermen to increase their effort.
Mauritanian fishmeal plants have even brought in a completely new fleet of efficient Turkish purse seiners to supply them with fish.
Senegalese fishermen from Casamance are now landing catches at fishmeal plants in Gambia. Sometimes these landings are so big that even the fishmeal plants cannot absorb them. As a result, considerable quantities of sardinella have to be dumped at sea or on the land."
Fishmeal Factories Threaten Job Security, Cause Pollution
Job security is also being threatened. Senegal's national dish, known as thiéboudiène, features smoked sardinella, which are carefully dried and smoked by thousands of women working in the sardinella smoking industry.
Whereas the demand for smoked sardinella was once high from local markets, now this activity is threatened because fishmeal factories are buying up all the sardinella, paying twice as much as the women fish smokers can, "leaving them with nothing but time on their hands," Reuters reported.10
The women can no longer afford to purchase fresh sardinella, leaving them out of jobs and the local residents without smoked sardinella to enjoy. Many fishermen are also wondering if they'll soon be forced to find a new line of work.
Gaoussou Gueye, a veteran fishmonger, told news outlet DW, "When the ships go out to sea together, there are not enough fish and they return without any catch. People are thinking there are no more fish left ... If we still had enough fish in Senegal, we would not to have to look for licenses in other countries to fish."11
What's more, the fishmeal factories are causing air and water pollution along the coast. Physicians in the area have even reported an increase of illnesses related to the pollution. Moctar Ame, an ear, nose and throat specialist in Nouadhibou, a city with more than 20 fishmeal factories, told DW that 20 percent of his patients have diseases caused by the factories' pollution:12
"There are many diseases that are directly related to the pollution of these factories. They release toxic air particles. When these particles enter the body, they cause allergies, chronic bronchitis and skin rashes. We cough a lot and have infected throats because of these particles."
Ninety Percent of Fish Used for Fishmeal Could Be Eaten by Humans Instead
The notion of fish farming becomes far less sustainable when you consider that growing fish is using up valuable supplies of fish that could be eaten directly by humans.
A study published in the journal Fish and Fisheries even revealed that most fish destined for fishmeal production are food-grade or prime food-grade fish that could be used to feed people.13 Study author Tim Cashion, research assistant at Sea Around Us, told NPR:14
"I was expecting there to be more truth to the argument that most of these fish don't have a place for human consumption, that there's generally not a market or a possibility of a market for these fish, but that's not what we found ...
In a world with many food insecure populations and people that could substantially benefit from having more fish in their diet ... that we're using 20 million tons of fish to feed aquaculture and livestock production? I think people should care about that."
Many farmed fish species, including tilapia and carp, are fed fishmeal. Further, about 30 percent of fishmeal production is used to feed CAFO animals including pigs and chickens. The types of fish used for fishmeal are also expanding to include not only sardinella and similar fish like anchovies, but also pompanos, drums and even some crustaceans.
It's a concerning finding, considering human exploitation, including overfishing, is the major cause of declining marine species, with some declining in numbers by 74 percent between 1970 and 2010.15
Farmed Fish Spread Diseases to Wild Fish
Aside from threatening wild fish stocks for the production of fishmeal, farmed fish also threaten wild fish by spreading disease, including sea lice and piscine reovirus (PRV). Sea lice are tiny parasitic crustaceans that feed on salmon skin and mucous. Just one or two sea lice can kill a juvenile salmon, with the lice literally eating the salmon alive, and adults may also be harmed if infestations occur.
As noted by Watershed Watch Salmon Society, "Even if average sea lice levels are kept 'low' on a farm, even very low numbers of lice per farmed salmon can add up to billions of sea lice eggs being released into surrounding waters."16
PRV, meanwhile, causes Heart and Skeletal Muscle Inflammation (HSMI) disease, which can be deadly to salmon. One study of salmon in British Columbia, Canada, revealed the proportion of PRV infection in wild fish was related to exposure to salmon farms.17
PRV was detected in 95 percent of farmed Atlantic salmon and up to 45 percent of wild salmon from regions highly exposed to salmon farms. In contrast, only 5 percent of wild salmon living in regions farthest from salmon farms were infected.
Not Good for Oceans, Not Good for You
Nutritionally speaking, farmed fish are also a far inferior choice to the wild variety. For starters, their pens are often placed near shore, which means they're close to land-based sources of pollutant runoff. In addition, their diet of ground-up fishmeal may lead to concentrated levels of toxins like PCBs.
In a global assessment of farmed salmon published in the journal Science, PCB concentrations in farmed salmon were found to be eight times higher than in wild salmon.18 What makes fishmeal so toxic? In some cases, the fish used to make the feed comes from polluted waters.
Some of the toxicity also stems from the manufacturing process of the pellets. The fatty fish are first cooked, resulting in two separate products: protein meal and oil. While the oil has high levels of dioxins and PCBs, the protein powder also adds to the toxicity of the end product. To this protein powder, an "antioxidant" called ethoxyquin is added.
According to the documentary "Fillet-Oh-Fish," this is one of the best kept secrets of the fish food industry — and one of the most toxic. Ethoxyquin was developed as a pesticide by Monsanto in the 1950s. Its use is strictly regulated on fruits, vegetables and in meat, but not in fish, because it was never intended for such use.
The effects of this chemical on human health have never been established. The one and only study ever done on ethoxyquin and human health was a thesis by Victoria Bohne, a former researcher in Norway who made a number of disturbing discoveries, including the fact that ethoxyquin can cross the blood-brain barrier and may have carcinogenic effects.
Are There Any Healthy Seafood Options?
Because much seafood is polluted, I only recommend eating safer seafood choices such as wild-caught Alaskan salmon, sardines, anchovies, mackerel and herring. All of these are at low risk of contamination, yet are high in healthy omega-3 fats. You'll want to opt for sustainably harvested wild-caught fish as well.
One of the best options toward this end is to look for the Marine Stewardship Council (MSC) logo, which features the letters MSC and a blue check mark in the shape of a fish. The MSC logo ensures the seafood came from a responsible fishery that uses sustainable fishing practices and meets the following standards:19
Fish stocks are sustainable — there are enough fish left in the sea to reproduce.
Environmental impacts are minimized — fishing operations must be carefully managed to maintain the structure, productivity, function and diversity of the marine ecosystem.
Effective management — the fishery must comply with relevant laws and have a management system that allows it to respond quickly to changes in the status quo.

Fish food production equipment,fish feed pellet
Most of the fish food sold on the market is produced through batch processing of fish food production equipment, which usually goes through multiple processes such as crushing, batching, mixing and processing, pelletizing and drying. The main machines and equipment for the production of fish food are.
 1、Crushing machine: the raw materials for the production of fish food will be crushed machine.
 2、Mixing machine: the crushed fish food raw materials will be added a certain proportion of water, additives, mixed evenly.
 3、 loading machine: the mixing of raw materials will be transported to the feed hopper of the twin-screw extruder. So come to see the animal feed mixing machine.

4、 twin-screw feed puffing machine: mixed raw materials in a high-temperature, high-pressure environment and twin-screw extrusion, extrusion through the feed mold, adjusted to the same size and length of feed particles.
 5、Conveyor: the produced fish feed pellets are transported to the multi-layer drying equipment.
 6、Multi-layer dryer: general oven, including electric oven, fuel oven, gas oven and steam oven, which can adjust the temperature by itself, used to dry the feed pellets to safe water content and increase the shelf life.
 7、Spraying and seasoning line: including oil spraying machine and seasoning cylinder for spraying oil and food attractant, etc., mainly spraying oil on the surface of feed and removing burrs and burrs on the surface of fish feed pellets to make the surface of feed pellets smoother.
 8、Cooling conveyor: reduce the temperature of the surface of drying feed pellets, promote the solidification of grease, and facilitate packaging.
 9、Vibrating sieve: sieve the excess external scattering material and granule debris.
 10、Packing machine: to pack and seal the made fish food.
  So you can come to see the types of fish feed machines in Lima.
