Cryptocurrency for Climate Change

Many of us are aware of the current situation of our beloved planet earth and of that global warming is one of the serious issues since from the start. Science and technology have helped both ways in the degradation of our planet earth as well as in a positive way too.

In this blog we are going to talk about Cryptocurrency and does it result in climate change or not? I

am very sure that most of us are still unaware of the term Cryptocurrency or maybe few of us already know about it. Let’s clear what it actually is and know its pros and cons.

What is Cryptocurrency? In simple words, Cryptocurrency is a virtual or digital currency that takes help of cryptography for security. The whole cryptocurrency process works most importantly on blockchain technology. The most famous cryptocurrency is Bitcoin which was the first blockchain based cryptocurrency introduced. As of now, there are thousands of alternatives of Bitcoins also known as “altcoins” working in the world. Of them, the most familiar are Ethereum, EOS, and Cardano all of these holds the aggregate value of over $120 billion. Bitcoin holds 50% of all.

Cryptocurrency doesn’t have any centralized authority for controlling the transactions. Each cryptocurrency functions through distributed ledger technology, usually a blockchain that serves as a public financial transaction database.

This whole process and as per the future need, it requires a huge amount of electricity, which is why many types of research have been conducted in the past on bitcoin. As per the researches, it was concluded that due to the use of high level of electricity in the bitcoin it has resulted in climate change. As soon as this research was claimed steps were taken by many cryptocurrencies in order to save our planet earth.

What possible steps are taken or can be taken? After this whole scenario, the possible steps that are taken are the use of renewable energy instead of fossil fuel energy. It’s right the cryptocurrencies can use solar energy or windmill energy in order to produce a large amount of electricity. Few have already started and few have also opted for thermal power plant projects in order to save the planet earth from serious issues like global warming.

Do you know blockchain technology can fight climate change? Blockchain technology is one of the important parts of cryptocurrency without which the cryptocurrencies wouldn’t be able to perform at all. Bitcoin was the first to introduce this technology to the world and no doubt it is famous.

Now you might be wondering how blockchain technology is going to help us against climate change? Well, Humans with the help of science and technology have served and helped the world in various ways. Blockchain technology might not be familiar to many of us still but you won’t believe that it has already taken into consideration in many European countries already.

Let’s study in depth more than how this technology which is used as a list of records in the cryptocurrency can help us fighting the climate change.

Blockchain Technology. Blockchain was invented by the founder of bitcoin in 2008 in order to serve as the public transaction ledger of the cryptocurrency bitcoin. Blockchain plays an important role in the formation of digital currency that works without any central server or trusted authority. The primary use of this technology is to record transactions or as a distributed ledger for cryptocurrencies.

There are three types of blockchains.

• Public Blockchains

As per the name, it suggests that it is a blockchain that is open source and the public to all where no one is in charge. There is no rights or access management done for a public blockchain and anyone can be a part of the consensus. The most common examples of public blockchains are bitcoin and Litecoin.

• Private Blockchains

Goes with its phrase private this blockchain is opposite of the public blockchain. It is because every function that is open for all on a public blockchain aren’t open here to all. The best example of this private blockchain is Bank chain.

• Consortium Blockchain

Consortium blockchain differs from their counterparts public blockchains in that they are permission, but not just anyone with an internet connection could get access to a consortium blockchain. Hence, they are also known as semi-decentralized. Cryptocurrencies like Quorum and Corda are best examples of Consortium Blockchain.

After reading the above paragraphs I am sure that you are aware of this blockchain technology is, Now let’s know how does blockchain technology help fight against climate change?

While the UN Climate Change Conference, a lot of attention was put to the blockchain. Mostly for the protection of the data as it is regularly verified by its user and it’s a distributed database. Every information in the blockchain is kept on multiple blocks or servers. It is impossible to make a change in one block without others. Thus, it makes it being used by multiple parties, but with solid protection. All these pros make blockchain very useful in climate change tackling.

Where it can be applied? The most noticeable and important thing about blockchain was its provision of transparency. Which makes it easier for different parties and structure trading data to perform. This information will help to discover waste quotas and find a way to cut them.

With blockchain, we can avoid some energy trading drawbacks. The system can make certification processes easy and make small trades possible. Energy producers will get a chance to set their own value despite big corporations. Experts conclude blockchain can put green power in the hands of consumers. And already we have an interesting example.

The Netherlands, as an example, is operating on a new European Waste Transportation. This whole new operation is using blockchain technology. The supervisor of waste transportation in the EU is going to apply this process. Blockchain system will promise real-time control for all government companies and bodies. Also, it can free up human resources for more disputed tasks.

Conclusion. From all the above words and facts, we can conclude that, although the use of cryptocurrency has proved harmful for our climate, we can also help it in many ways. Blockchain technology which is an important part of cryptocurrency can help in fighting against climate change.

Address Security Concerns

Security considerations such as identity and access management are crucial when building a blockchain network. Suitable security services, such as AppID, should be used to ensure that participants have granular access.

Data privacy is another critical element that needs to be addressed by segregating the data into four segments – personal, business, legal, and operational, using channels, private data collection, encryption, zero-knowledge proofs, and off-chain databases based on the requirements.

Seek the finest blockchain development services from our experts at Blockchain Firm, who have more than 5+ years of experience.

Have A Clear Integration Strategy

Having a clear integration strategy for both inbound and outbound data is essential. REST APIs, and messaging like Kafka, SFTP, ETL, and others, can be used for importing and exporting data with your DLT. It is also necessary to discuss with participating organizations the necessity of integrating with existing enterprise IDP on their side so that SSO (Single Sign On) is implemented.

Choose The Right Infrastructure And Data Storage

Choosing the right infrastructure and data storage for your network is vital. Based on the network vision and nature of all your business participants, you can choose single-cloud, multi-cloud, on-premises, or hybrid infrastructure. You can also use containers, applications, and API components to be deployed and integrated with external systems. Finally, choose the data to be stored both on-chain and off-chain based on your data model, expected performance indicators, and the data usage in multiple personas and participants.

Wrap Up

A comprehensive approach to building a scalable and sustainable blockchain business network must consider the technology perspective, including infrastructure, security, integration, deployment, and operational aspects.

Ethereum News and Links

Constantinople postponed

The day before the scheduled Constantinople upgrade fork, ChainSecurity found that EIP1283 potentially allowed deployed contracts to be vulnerable to a re-entrancy attack. There was no bug in the EIP per se, but it broke an implied invariant for a small but then-indeterminate amount of deployed code. Hence, out of an abundance of caution but with limited time for the community to come to consensus, Constantinople was successfully postponed.

A full post-action report by Trail of Bits, ChainSecurity, and Eveem. They proffer a different alternative to 1283 - refund difference of intended cost of writes. Magicians thread on 1283 alternatives and thread on invariants.

Ordinary Stablecoin or XRP Killer? What We Know About JPMorgan Chase's New Cryptocurrency

New Post has been published on http://blog.hodlthrive.com/?p=205

Ordinary Stablecoin or XRP Killer? What We Know About JPMorgan Chase's New Cryptocurrency

Ordinary Stablecoin or XRP Killer? What We Know About JPMorgan Chase’s New Cryptocurrency

                                  On Feb. 14, United States banking behemoth JPMorgan Chase

announced its own cryptocurrency. Significantly, it is the first time a major U.S. bank has tapped into digital assets for direct use in business operations. It is fair to say that move comes unexpectedly for JPMorgan Chase, whose CEO, Jamie Dimon, is famous within the crypto community for his anti-Bitcoin (BTC) remarks. Here are the main outtakes from reports and comments about the new virtual currency, dubbed “JPM Coin.”

JPM Coin aims to increase settlement efficiency, initially within three of its operations

There are three early applications for the JPM Coin, as Umar Farooq, head of the lender's blockchain projects, told CNBC. The first one is cross-border payments for large corporate clients, which currently rely on wire transfers provided by networks like SWIFT, meaning that they might take up to several working days to settle. According to Farooq, payments using JPM Coin will be instantly performed at any time of day.

As a result, SWIFT, which currently handles more than half of all high-value, cross-border payments, might be additionally challenged to update its remittance system. The 46-year-old Belgium-based interbank messaging service has already been confronted by Ripple (XRP), whose CEO, Brad Garlinghouse, had recently declared that “what we are doing on a day-to-day basis is in fact taking over SWIFT.” Ripple has reported various advancements on the field of international payments, allegedly saving transaction costs by 40-70 percent with its xRapid platform and adding several major banking institutions to its RippleNet network.  

SWIFT, in turn, has already started researching blockchain as one of the options to achieve quicker payments. Additionally, it has been boosting its Global Payments Innovation (GPI) payments platform — just recently, the banking network launched a proof-of-concept (PoC) of a gateway that would allow blockchain software firm R3 to connect to the GPI. Secondly, JPM Coin will reportedly be used for securities transactions. In April, the bank tested its Quorum Blockchain platform, along with with the National Bank of Canada and other lending sector participants. The intent was to streamline origination, settlement and interest rate payments, among other financial processes. Specifically, as Reuters wrote, the trial “mirrored the Canadian bank’s $150 million offering on the same day of a one-year floating-rate Yankee certificate of deposit.” Thus, institutional investors can use the JPM Coin for instant settlements, as opposed to waiting for a wire transfer to come through.

JPMorgan Chase created Quorum in 2016 as part of the Ethereum Enterprise Alliance (EEA), of which it is one of the founding partners. The platforms runs on the Ethereum (ETH) blockchain and is modeled after the Ethereum Go client. It is currently used by pharmaceutical companies Pfizer and Genentech as well as Microsoft Azure, among others. In March, JPMorgan Chase declared that they were considering making Quorum an independent entity as way to attract more partners that could be scared off if they are competitors of the bank. Finally, the new cryptocurrency might be employed by large corporations including Honeywell International and Facebook, which will reportedly use JPMorgan Chase's treasury services business to replace the funds they hold in various subsidiaries across the world. According to CNBC, that businesses brought the lender $9 billion in revenue in 2018.

Farooq explained in a comment:

"Money sloshes back and forth all over the world in a large enterprise. Is there a way to ensure that a subsidiary can represent cash on the balance sheet without having to actually wire it to the unit? That way, they can consolidate their money and probably get better rates for it."

The trials for the token are set to start “in a few months.” However, only a small amount of the total funds involved in the three aforementioned areas would involve JPM Coin at first. In total, JPMorgan Chase moves more than $6 trillion across the world on a daily basis, according to CNBC. It is the largest bank in the country.  

As Farooq told:

“Pretty much every big corporation is our client, and most of the major banks in the world are too. Even if this was limited to JPM clients at the institutional level, it shouldn't hold us back.”

He also added that, in the future, the lender’s token could be used for payments on internet-connected devices if they are migrates to blockchain. Overall, the JPM representative seemed enthusiastic about the technology’s perspectives

at the bank.

“So anything that currently exists in the world, as that moves onto the blockchain, this would be the payment leg for that transaction.The applications are frankly quite endless; anything where you have a distributed ledger which involves corporations or institutions can use this.”

JPM Coin resembles a stablecoin — which falls in line with a general trend

According to the CNBC report, JPM Coins are pegged to U.S. dollars so that its value stays stable — technically, that makes the new token a stablecoin, at least in its initial form. Clients will reportedly be issued the coins after depositing dollars at JPMorgan Chase. After the tokens are used for a payment or security purchase on the blockchain, the lender will allegedly destroy them and give clients an equivalent amount of fiat in return.

Overall, stablecoins had a great year in 2018, becoming a growing trend among the market’s most compliance-oriented players. For instance, Goldman Sachs-backed startup Circle launched its USD Coin (USDC) in collaboration with major U.S. crypto exchange Coinbase, and the Winklevoss twins presented their own stablecoin dubbed the Gemini dollar after receiving the regulatory green light from the New York Department of Financial Services (NYDFS).

JPM Coin will run on Quorum, the bank’s private ETH blockchain

According to an FAQ released by JPM on the same day CNBC broke the news, its token will initially be powered by the aforementioned Quorum blockchain (which is permissioned, or, in other words, private), but will also become applicable to “all standard blockchain networks” in the future. “The JPM Coin will be issued on Quorum Blockchain and subsequently extended to other platforms. JPM Coin will be operable on all standard Blockchain networks,” the guide says. Based on that, Jerry Brito, executive director at Coin Center, a nonprofit research and advocacy center focused on cryptocurrencies and blockchain, told MarketWatch that JPM merely launched an in-house payments system rather than

an actual cryptocurrency:

“There’s a lot of confusion. […] I see folks referring to it as a cryptocurrency. It’s not a cryptocurrency. A cryptocurrency is one that is open and permissionless. If you want to download it, you don’t need permission, you just need some software.”

Further, JPM Coin will eventually expand its role beyond being a stablecoin, as per the FAQ:

“Over time, JPM Coin will be extended to other major currencies. The product and technology capabilities are currency agnostic.”

As for now, the token is designed to be used by JPM’s institutional clients only. Michael Dowling, CEO and founder of FairX, a financial services company involved with banking and cryptocurrencies, and former chief technology officer at IBM’s blockchain division, told Cointelegraph that JPM Coin is “no different/better than any other stablecoin issued by a fintech rather than a bank.”

Dowling argues that JPMorgan Chase’s new digital asset has not been approved as a value transfer instrument by the Office of the Controller of the Currency (OCC), the bank’s chief regulator. Further, he stresses that it is only usable within JPMorgan Chase's “little walled garden,” and has allegedly been tested with just one client. “My guess is this is JPM poking the regulatory bears,” Dowling added.

The bank’s CEO, Jamie Dimon, might be anti-Bitcoin, but he is also pro-blockchain

JPMorgan Chase became notorious among cryptocurrency participants in 2017, when its CEO, Jamie Dimon, openly called Bitcoin a “fraud.” In 2018, Dimon reterierted his position by saying that he doesn’t “really give a s—” about Bitcoin. However, at the 2019 World Economic Forum in Davos, when the JPMorgan Chase CEO was asked if he took any satisfaction when the cryptocurrency plunged last year, he replied negatively and followed with positive comments about the technology that backs it. Specifically, Dimon noted that he is pro-blockchain, despite the excessive hype around the technology. In his view, blockchain is a better replacement for certain

online databases:

“Blockchain is a real technology — it’s just a database we can all access that’s kept up-to-date.”

Indeed, the banking giant has been researching blockchain since 2016, when Quorum’s white paper was first published.

The announcement has received mixed reaction from the community

Changpeng Zhao, the CEO of Binance, greeted the first U.S. banking cryptocurrency, referencing Mahatma Ghandi’s "first they ignore you, then they laugh at you, then they fight you, then you win”

alleged quote:

First they …, then they …, then they…, then you win!  Welcome to the real world, JPM!

Cointelegraph has reached out to Ripple for an additional comment on the matter. In response, the Ripple team sent the link to the tweet of their CEO Brad Garlinghouse, who, in turn, criticized the concept of bank-issued digital coins (which he calls “bank coins”) and JPM Coin specifically, citing its

centralized structure:

As predicted, banks are changing their tune on crypto. But this JPM project misses the point – introducing a closed network today is like launching AOL after Netscape’s IPO. 2 years later, and bank coins still aren’t the answer.

Notably, two years ago, Garlinghouse wrote an article in which he argued that such projects — where bank remittances are performed using unique digital tokens — are misguided and would inevitably result in “an even more fragmented currency landscape than what

we have today”:

“If banks of different digital asset groups want to settle trades with one another, they’ll have to make markets between their unique digital assets or trade between their digital assets and a common fiat currency. What a mess!”

However, some community members seem more confident about JPM Coin, suggesting that the new token is capable of achieving widespread use, and hence might overtake Ripple in the future. Multicoin Capital partner

Tushar Jain wrote:

Banks were obviously never going to use XRP for settlements and enrich Ripple Inc (who owns more than half of all XRP). They would rather enrich themselves instead! Kudos to JPM for being first. They are going to wipe the floor with Ripple.Bloomberg business editor Joe Weisenthal expressed a somewhat similar viewpoint If it turns out that the Blockchain/Coin framework turns out to be a good one for banks transferring money around, then the JPM Coin should absolutely obliterate Ripple.While it might be too early to tell whether JPM Coin will be transferred to public blockchains and gain wider recognition among crypto market participants, some seem perplexed by its current capabilities. Thus, Nathaniel Popper, author of the book “Digital Gold, a History of Bitcoin,”

The JPM Coin makes it possible to move dollars between JPMorgan bank accounts instantly. That raises the question: Why was it not already possible to move dollars between two JPMorgan bank accounts instantly?

Why is the Ethereum Blockchain Beneficial for Business?

Ethereum is a decentralized blockchain platform that creates a peer-to-peer network for safely executing and verifying application code, or "smart contracts," also known as smart contracts. Smart contracts enable participant-to-participant transactions without the need for a reliable central authority. Due to the immutable, verifiable, and secure dissemination of transaction records throughout the network, participants have full ownership and visibility over transaction data. Ethereum transactions are sent and received by user-created accounts. As part of the network's transaction processing fees, senders must sign transactions and use Ether, Ethereum's native coin.

What are the needs of the Business?

On a peer-to-peer network, businesses have vastly different needs than individual consumers. Regardless of whether they are providing IDs, carrying out trades, tracking shipping containers, or labeling pharmaceutical products, businesses must manage sensitive data in high volume, monitor quality, and hold themselves accountable to the safety and regulatory standards in their respective industries. For a high-performance company, security, certainty, and accountability at scale are essential. A business or start-up can leverage the services of an Ethereum Blockchain Development Company for setting up the best blockchain for their organization.  Enterprise requirements can be divided into four groups:

Privacy. 

Depending on the participants' roles, certain transaction data, such as product name, amount, price, address, personally identifiable financial information, etc., should either be hidden from or made available to them. For instance, a freight forwarder might just need to be aware of the arrival of a container rather than its contents. Access to transaction data is likewise restricted by banking laws.

Performance

A company's infrastructure must be able to handle thousands of transactions per second and endure sporadic spikes in network activity. A series of transactional events are started by, say, a sales order with 1,000 lines. Enterprises must be able to gather, validate, and publish an ever-increasing volume of varied transactions in today's networked economies.

Finality

Institutions moving significant sums of money want assurance regarding the results of transactions. Payments must be final and funds must be in good standing.

Permissions

Enterprise use cases frequently demand that various participants have varied read, access, and write roles and that only authorized parties can join the network.

Benefits of Ethereum Blockchain for Business

The characteristics of Ethereum include being open, free of charge, adaptable, and suitable for multiparty collaboration. While Ethereum performs similarly to a distributed ledger in terms of data coordination, its architecture also includes special layers that both support and expand the capabilities of commercial systems.

-Synchronization of Data 

The decentralized architecture of Ethereum better distributes knowledge and trust so that network users are not dependent on a central authority to run the system and mediate transactions.

-Deploy quickly

An organization may quickly build and administer private blockchain networks with an all-in-one SaaS platform rather than coding a blockchain implementation from scratch.

-Licensed networks 

Businesses can build on either public or private Ethereum networks thanks to the open-source ConsenSys Quorum protocol layer, which guarantees that your solution complies with all applicable security and regulatory requirements.

-A network's size 

The Ethereum main net demonstrates that a network with millions of users and hundreds of nodes can function. The majority of enterprise blockchain rivals are only operating networks with fewer than 10 nodes, and therefore lack a reference case for a sizable and functional network. For enterprise consortiums that will inevitably outgrow a small number of nodes, network size is crucial.

-Private exchanges

By creating private consortia with private transaction layers, businesses can increase the privacy granularity in Ethereum. Private information is never broadcast to network users on ConsenSys Quorum. Only those parties who need to see private information are given direct access.

-Scalability and effectiveness Based on network setup, consortium networks built on Ethereum can grow up to hundreds of transactions per second or more and outperform the public mainnet thanks to Proof of Authority consensus, custom block time, and gas limit. Scaling techniques at the protocol level, such as sharding and off-chain, as well as layer 2 techniques, such as Plasma and state channels, provide Ethereum the chance to soon boost its throughput.

-Finality 

The consensus method of a blockchain ensures trust that the transaction log is canonical and tamper-proof. For various enterprise network instances, Ethereum offers customizable consensus techniques like RAFT and IBFT, providing immediate transaction finality and lowering the necessary infrastructure that the Proof of Work algorithm requires.

-Layer of incentives 

With the help of Ethereum's crypto-economic layers, business networks can design mechanisms to deter bad behavior and reward actions like availability and verification.

-Tokenization

Any asset that has been recorded digitally by a business can be tokenized on Ethereum. Organizations can diversify their product lines, create new incentive models, and fractionalize once monolithic assets (like real estate) by tokenizing their assets (crowdsourced data management).

-Standards

The industry standards are on Ethereum. The ecosystem is prevented from fragmenting through protocols for token design (ERC20), human-readable names (ENS), decentralized storage (Swarm), and decentralized messaging (Whisper). The Enterprise Ethereum Alliance's Client Specification 1.0 lays out the structural elements for enterprise blockchain implementations that comply with its requirements. The EEA intends to publish version 2.0 of the specification soon.

-Open Source and Compatibility 

On Ethereum, consortiums are not confined to the IT infrastructure of a single vendor. Customers of Amazon Web Services, for instance, can run private networks using the Blockchain Business Cloud from Kaleido. The Ethereum ecosystem welcomes improvements to the codebase through Ethereum Improvement Proposals, similar to the Java community's spec-driven methodology (EIPs).

The Bottom line

Blockchains have the potential to significantly enhance corporate processes or even open the door to brand-new industries. In each instance, the fundamental characteristic that distinguishes blockchains from other types of technology is that they offer certainty about what will occur in the future: asset ownership, payments, and other business transactions will adhere to pre-established rules, and the system's rules and data are extremely resilient to change by outside forces. 

To attain such predictability in the past, businesses generally relied on institutions like laws, contracts, and courts, but blockchains can do it more effectively, quicker, and more cheaply. So, Ethereum Blockchain can help in many ways to get your business up to the next level. Looking for the best Ethereum Blockchain developers? Here’s your best bet. Hire Blockchain Developers at Innosoft and get your business growing with the advanced technology of today - Ethereum Blockchain.

Top 5 Smart Contract Audit Tools

One of the most important factors in the success of a blockchain project is its security. The audit of smart contracts is a crucial step in ensuring a project's security. An application's smart contract sets may be accurately and thoroughly analysed to find and remove vulnerabilities. The audit confirms the accuracy of the contract contacts as well.

The audit method for smart contracts is quite similar to code testing in general. Testing smart contract state changes, testing events, testing errors, and inspecting message senders are the steps.

What to look for when choosing tools.

However, smart contracts are just too big and dynamic to manually investigate and supervise. To completely evaluate the code and guard against any data breaches, you need the right tools. In some circumstances, you need a system to continuously monitor transactions and alert participants right away if anything questionable is found, even after a project gets off the ground.

An ecosystem that makes it simple to operate with the smart contract across its full life cycle is a crucial prerequisite for a tool. It enables you to construct customized contracts—specific computer code written to meet your requirements. Contract implementation and auditing are both successfully possible in a live setting.

A smart contract must be monitored after implementation to maintain security. The programme keeps track of a specified collection of contracts in real time and generates personalised notifications when the predetermined parameters are broken.

One of the finest places to learn about various smart contract vulnerabilities is SWC Registry.

Here are five well-liked tools for smart contract auditing:

1. Truffle

Truffle is a well-liked framework for building blockchain applications that functions as a reliable asset pipeline, testing framework, and development environment for blockchains. The framework is reliable regardless of whether programmers want to build on top of Ethereum, Hyperledger, Quorum, or any other supported platform. Truffle offers the features required to serve as a whole dApp development platform.

Truffle is a Node.js platform that is primarily used for creating, connecting, and deploying smart contracts. Developers have access to capabilities like programmable deployment, support for customised deployments, access to other packages, binary management, and many more.

Truffle includes built-in capabilities for smart contract compilation, binding, deployment, and binary management.

•           Programmable, extensible framework deployment and migrations

•           Email proof of contract

•           Independent network

•           Package Management with EthPM and NPM. Use standard ERC190

•           Interactive console for direct contractual communication

•           Configurable build pipeline backed by integration

Without doing a lot of client-side code, Truffle enables developers to quickly construct smart contracts and interface with their underlying state. A helpful library for auditing and iterating smart contracts is provided by the framework.

2. MythX

MitoX is a potent cloud-based service that identifies robustness flaws in Ethereum contract code. The service employs input fuzzing and symbolic analysis to find common security flaws. To utilise the service, the client needs an API key.

Static analysis, dynamic analysis, and symbolic execution are just a few of the analytic services that MythX will be launching. The service provides choices like rapid scan, regular scan, and thorough scan depending on the membership level. To examine smart contracts in the Truffle framework, utilise the Truffle MythX plugin.

3. Rattle

An EVM binary static analysis framework reserves up to 60% of bytecode retrieved instructions, shortens things and scans for vulnerabilities.

To recover the original control flow graph, obtains the bytes strings and applies flow-sensitive parsing. It enhances SSA by removing DUPs, SWAPs, PUSHes, and POPs and pushes the control flow graph to an endless SSA/log form. This simplifies the stack machine's interface, making it straightforward for anyone to interpret smart contracts.

4. Secure

You may copy and paste code using the web-based smart code scanner Securify. When you select "scan now," the tool will report any issues and issue warnings.

The tool directly detects problems at the line of potentially dangerous code. You may get additional information and samples by clicking the "info" button. It will display problems such how the sequence of transactions impacts the quantity of ether, unfettered writing to storage, the lack of input validation, unrestricted ether flow, unsafe and unreliable contract calls, etc. The online tool, however, cannot be utilised offline.

5. Mithril

Using control flow verification, contamination analysis, and concolic analysis to find several security flaws in smart contracts.

It is an EVM bytecode security analysis tool intended to find security flaws in smart contracts created for the Ethereum, Quorum, Hedera, Vechain, Roostock, and other EVM-supported blockchains. Mythril is a tool that is used in combination with other methods and tools on the MythX security analysis platform.

Ending

A smart contract audit is a key enabler for running secure DeFi applications that thrive in the capital market later on. Tools play a critical role in agile auditing, allowing teams to pass thousands of lines of code quickly. Choosing the right tool also influences the effectiveness of the audit.

Top 3 use cases of blockchain technology that enterprise software use

 Government OrganizationsMedical services

Enterprise blockchain refers to the use cases of blockchain technology in commercial software products rather than to the technology itself. The corporate blockchain, according to blockchain specialists, is the ideal solution for major businesses to meet all of their requirements. These application cases of blockchain may be better understood with a Blockchain course. In this section, we'll look at three of the most popular blockchain applications for corporate software. What it is, how it works, and how it might be used in various scenarios are all covered.

 What is an enterprise blockchain?

A blockchain is a distributed system that relies on decentralisation for its success. It fosters a sense of trust, openness, and stability. The blockchain may be thought of as a list of linked squares. Connected records and pointers are used to do this.

In addition, a corporate blockchain provides critical features that enable operation on a large scale possible. The blockchain has an entirely distinct set of needs for businesses. Another need is for an effective and efficient blockchain solution. Complex needs may be handled by the business blockchain, according to specialists in the field.

 Enterprise Blockchain Use Cases

In this article, we'll go through the three most common ways that corporate blockchain may be put to use in business applications.

  Banking and Finance

Big business blockchain has been most warmly received by the financial industry. Business blockchains come in many shapes and sizes. When it comes to a blockchain arrangement for money, Quorum is a good example.

The reform is also being supported by a big number of exchange finance groups. As an example, several of the world's largest financial institutions are working on blockchain technology. They're working on a better blockchain so that specialists and other key groups can collaborate.

This might save the banks and financial sector a lot of money. Cross-line settlements, for example, may save them money.

The future of exchange-traded funds is really promising. It will have a significant impact on a wide range of financial markets. The financial trade and the necessity for transparency will be well-understood via blockchain technology training. But in order to come up with a reasonable solution, we need to know what it will influence.

 1. Worldwide Payments

2. Exchange Finance

3. Mechanized Compliance

4. Partnered Loans

5. Protection - P and C Claims Processing

Government Organizations  

States have a razor-sharp focus on blockchain. When everything is said and done, it has the potential to alter the way an administration runs. It is possible for them to improve their frameworks via the use of the blockchain technology.

Governments with more sophisticated capabilities may also mobilise assets such as resources such as land and businesses to form a more decentralised structure. It improves productivity in several ways.

Ultimately, what's in store for the public authority that employs blockchain? Many things, to be sure. As an example, every government may create a GovChain Stack. It also touches on a variety of government functions. Executives will like the clear standards and detailed budgeting that are part of the package as well. The government may one day have its own blockchain platform for citizens to access.

The public authority can use blockchain in more than one way.

1. Instruction and expert capabilities

2. Shrewd urban areas

3. Credits

4. Following Vaccinations

5. Finance Tax Collection

  Medical services

It's no secret that medical institutions are always looking for new methods to cope with their own cyclical nature. The current state of medical care needs a major overhaul. There is no real connection between the several warehouses. There are various issues in the medical profession, including the theft of patient data and the distribution of counterfeit medications.

After this, patients still have to bear the burden of reporting their findings. It's impossible for experts to access the patient's complete medical records in a single location. Drug credibility is another major struggle that has to be won. For patients, this is a major problem, since they are taking counterfeit pharmaceuticals that are causing them much more harm.

 All of the problems listed above can be solved with an enterprise-level blockchain. It removes the united components of information accumulation from the outset. In addition, it gives patients the freedom to retain and retrieve their medical data anywhere they choose. It is possible to monitor the whole supply chain thanks to the use of blockchain technology. It suggests that the problem of phoney medications may be resolved in the end. So, if you want to create a medical app, you'll need to be well-versed in blockchain technology.

However, the future of medical care might drastically alter thanks to blockchain technology. ' It has the potential to impact patient consent, data security, drug detection, and a slew of other things.

 Conclusion

Blockchain's utility and appeal are both increasing at a fast pace. Blockchain technology has now being used by all enterprises. Blockchain is also essential for businesses because it provides security, transparency, and efficiency. Job opportunities in this industry are also increasing.. Students are becoming interested in blockchain education. It's not only businesses that are embracing blockchain technology. The future of one's profession may be bright with the help of blockchain technology. If you want to understand more about blockchain technology, now is the time.

Top 5 smart contract platforms

Future businesses will all rely on smart contracts. These programs are known to automate processes and lower money, energy, and time usage. Amazingly, they have already started making their presence felt. But, how can you create them? What are the best platforms for smart contracts? At present, the best smart contract platforms are Ethereum, Quorum, Hyperledger Burrow, Hyperledger Fabric, and Open Transactions. These are some amazing choices available for those seeking recommendations, but what you should really research is which platform is suitable to meet your particular requirements. That’s where things may get troubled. Genuinely, the selection depends on your requirement and whether you are ready to compromise or not.

Below here is a list of smart contract platforms and the languages they support. Ethereum and Burrow support a higher number of languages in comparison to the other platforms, thereby providing more flexibility.

Ethereum and Hyperledger Burrow support LLL, Mutan, Solidity, Vipe as well as Serpent.

Quorum supports Solidity

Open Transactions support ChainScript

Ethereum

It is an open-source, blockchain-reliant computing system. The node of the blockchain stores smart contracts. At present, it is one of the most renowned platforms to write smart contracts. Some of the benefits of using Ethereum are:

It is a well-developed solution and the most convenient to use.

There is no need for third parties to offer contract functionality.

A big community renders assistance to the blockchain ecosystem.

At present, Ethereum is using POW (proof-of-work) consensus and is not recommended to create a permissioned environment. Some POCs (proofs-of-concept) make use of the Ethereum testnet function for a private function, but it isn’t as convenient as the other platforms mentioned here.

Hyperledger Burrow

It is a permission-reliant, smart contract blockchains system developed by Monax. It is written in a top-level smart contracts language Solidityand offers several benefits:

Easy execution and tooling.

EVM (Ethereum Virtual Machine) to render security and run untrusted code worldwide.

Permissioned smart contracts along with permissioned hyperledger blockchain.

It makes use of proof-of-stake Tendermint just like Hyperledger Fabric.

Hyperledger Fabric

It is a blockchain structure developed by IBM and Digital Asset. It provides platforms to share private data, endorses policies for transactions, and runs smart contracts. It offers several benefits like:

Permissioned membership to give distinct identities to all participants.

Scalable, safe and modular base to ease blockchain transactions.

Simple architecture to allow developers to use their chosen implementations.

Hyperledger Fabric supports varied consensus algorithms that can be used in its three different phases.

Open Transactions

It is a crypto and virtual cash program library allowing users to issue and handle virtual assets and make new ones. In comparison to Hyperledger Fabric and Hyperledger Burrow, it is a non-chain framework meant to deal with asset management. It offers several benefits:

Easy implementation with assets that are the same as a typical banking system.

Digital asset management

The platform isn’t feasible for permissioned environments because the transactions are completed through third parties.

Quorum

It is an enterprise version of the ETH blockchain platform. Quorum is recommended for an app that needs high speed and good all-through processing of transactions within a permissioned segment of known people. It addresses challenges to blockchain technology adoption in the fiscal industries. It offers benefits like:

Heavy-performance from simple consensus functionality.

High contract privacy

Permissioned membership and better data protection.

Quorum makes use of several voting-reliant consensus mechanisms.

Smart contract platforms are on the rise, and the top 5 that we have highlighted above are some of the best in the world, these can be used to create a range of different smart contract ecosystems, and they also have a number of unique features which all make them unique in their own way. Smart contract platforms are set to play a big role in the future, and we hope that you are able to find one that suits your needs.

Tezos Governance

What is Self Amendment? Tezos is a self-amending blockchain network that incorporates an on-chain mechanism for proposing, selecting, testing, and activating protocol upgrades without the need to hard fork. How Does It Work? The self-amendment process is split into 5 periods: Proposal Period, Exploration Vote Period, Cooldown Period, Promotion Vote Period, and Adoption Period. Each of these five periods lasts five baking cycles (i.e. 20,480 blocks or roughly 14 days, 5 hours), comprising roughly 2 months and 10 days. Should there be any failure to proceed for a period, the whole process reverts to the Proposal Period, effectively restarting the whole process. 1. Proposal Period The Tezos amendment process begins with the Proposal Period, during which bakers can submit proposals on-chain. The baker submits the proposal by submitting the hash of the source code. In each Proposal Period, bakers can submit up to 20 proposals. A proposal submission also counts as a vote, which is equivalent to the number of rolls in its staking balance at the start of the period. Other bakers can then vote on the proposals by during the Proposal Period up to 20 times. At the end of the Proposal Period, the network counts the proposal votes and the most-upvoted proposal proceeds to the Exploration Vote Period. If no proposals have been submitted or if there is a tie between proposals, a new Proposal Period begins. 2. Exploration Vote Period In the Exploration Vote Period, bakers may vote on the top-ranked proposal from the previous Proposal Period. Bakers get to vote either "Yay", "Nay", or "Abstain" on a specific proposal. "Abstain" just means to "not vote" on a proposal. As in the Proposal Period, a baker's vote is based on the number of rolls in its staking balance. At the end of the Exploration Vote Period, the network counts the votes. If voting participation (the total of “Yay,” “Nay,” and “Abstains”) meets the target, and an 80% majority of non-abstaining baker approves, the proposal proceeds to the Testing Period. The voting participation target tries to match the exponential moving average of the past participation rate. If the voting participation fails to achieve the target or the 80% supermajority are not met, the amendment process restarts to the beginning of the Proposal Period 3. Cooldown Period Previously, during the voting process, a test chain would be spun up during the “testing period” which took place between the exploration and promotion voting periods. The intent was that this test chain be used to assure that the new proposal worked correctly, but in practice, the test chain has never been used in this manner, and has caused significant operational problems to node operators. The Florence upgrade eliminates the test chain activation; the testing period has been retained but is now named the “cooldown period”. Instead, testing the protocol continues by using test chains that operate outside of the mainnet voting process. 4. Promotion Vote Period At the end of the Testing Period, the Promotion Vote Period begins. In this period, the network decides whether to adopt the amendment based on off-chain discussions and its behavior during the Testing Period. As in the Exploration Vote Period, bakers submit their votes using the ballot operation, with their votes weighted proportionally to the number of rolls in their staking balance. At the end of the Promotion Vote Period, the network counts the number of votes. If the participation rate reaches the minimum quorum and an 80% supermajority of non-abstaining bakers votes “Yay,” then the proposal is activated as the new mainnet. Otherwise, the process once more reverts back to the Proposal Period. The minimum vote participation rate is set based on past participation rates. See the full details of the governance process. 5. Adoption Period The Adoption Period provides a "cool-down" allowing developers and bakers some additional time to adapt their code and infrastructure to the upgrade based on the results of the Promotion Vote Period. Following the

adoption period the protocol is activated. After this step the blocks added to the chain are interpreted in the newly activated protocol. As a result gas costs (and other such details of operation inclusion) may differ.
