Cryptocurrency mining or crypto mining is a process in which transactions for different cryptocurrency forms are confirmed and added to the digital block register. Also known as crypto coin mining, counos coin mining, or Bitcoin mining (for the most popular form of cryptocurrency, Bitcoin), cryptocurrency Mining increased both as a subject and activity, since the exclusive use of cryptocurrency experienced exponential growth in recent years. Each time a cryptographic transaction is made, the

Reaching Everyone, Pt. I: The Need For Sound Money Outside of the Wealthiest Territories
Tumblr media
ICYMI on In The Mesh, read the next parts there first.
This article is the first in a four-part series by Matt B (@MattoshiN) and Wassim Alsindi (@parallelind) on the use of Bitcoin and the technology stack built atop it to assist those living under oppressive regimes or in conflict zones, and those seeking to flee them.
In developed nations, the widespread adoption of Bitcoin may not seem all that urgent to many. Indeed, it would be reasonable to say that its need at the individual level hasn’t yet widely manifested itself. While everyone’s excited about Lightning Network transactions overtaking existing fiat gateways for buying coffee or paying for bus tickets, the fact is that if some critical security flaw caused the irreversible collapse of the Bitcoin network overnight, we’d survive. Life would go on. The legacy financial infrastructure is relatively stable in many nations — at least in the short-term. Where cryptocurrency can shine brightest is in areas where economic and/or political actions of governments are failing.
Indeed interest and use of Bitcoin and cryptocurrency generally appears to be on the rise in regions where individuals are desperately in need of forms of wealth and value transfer that cannot be confiscated, debased or censored by authoritarian governments, local mafias or cartels. This has traditionally been difficult.. The state printing press is a machine that, left unchecked, can recklessly and often surreptitiously add to the existing monetary supply in such a way as to cause hyperinflation, a disaster we’ve seen unfold in the Weimar Republic in the 20s and the latter stages of the Roman Empire, and in Venezuela, Iran and Zimbabwe at present. As for commodity monies, they have been subject to confiscation and dilution in the past — consider Executive Order 6102 in the US, where the government coerced citizens into turning over bullion and coins.
Aristotle defined the desirable properties of money in the fourth century BC as transportability, fungibility, scarcity and divisibility. Bitcoin largely satisfies the criteria above — analogous to the mining of precious metals, the generation of Bitcoin blocks requires significant expenditure on the part of the miner (hardware, electricity, infrastructure and running costs) to acquire a provably scarce asset with a total supply capped at 21 million coins. Arguably, this makes it rarer than gold, whose supply constraints are merely presumed, and current valuation does not account for that which simply isn’t economically feasible to extract — i.e. in Earth’s oceans or in space.
Like precious metals at present, synthesising a Bitcoin, outside of the parameters explicitly permitted by the network in the form of mining, is impossible. Any attempt at doing so would simply be incompatible with the network. Each coin can be divided into 100,000,000 units, and one UTXO (unspent transaction output) unit is functionally equivalent to another — though there are current limitations to the fungibility of Bitcoin insofar as tainting and blacklisting is concerned. (In an upcoming piece, we’ll be covering some in-protocol and extra-protocol solutions to these challenges).
Evidently, hard money existing in cyberspace would present numerous benefits over physical alternatives: concealability, plausible deniability, programmability, portability and easy global transmission. Precursors to Bitcoin such as Wei Dao’s b-money or Szabo’s bit gold made strides in the direction of solving key distributed computing problems involving the double spending of digital money, although they were imperfect as degrees of centralisation were required prior to the use of proof-of-work and chain selection rules as a mechanism to mitigate Sybil attacks and reach network consensus. Whilst there’s a push towards institutionalising Bitcoin as a marker of establishment acceptance, that was never what the cypherpunk and crypto-anarchist movements from which it originated saw as important. Both have always focused on liberating individuals by arming them with cryptographic tools and protocols to defend their sovereignty from would-be oppressors, hierarchies, rulers and dominators.
A 2017 report from Freedom House indicates that over half of the world’s countries are ruled by governance structures considered to limit citizen freedom. Of the 195 countries assessed, 87 (45%) were rated ‘Free’, 59 (30%) ‘Partly Free’, and 49 (25%) ‘Not Free’. A common theme that appears to prevail in countries deemed ‘not free’ is the exertion of monetary and economic domination as a key mechanism of social control. This is typically achieved by issuing weak or undesirable fiat currency, which does not retain purchasing power over time due to mismanagement of the monetary issuance policy due to incompetence or malice — or some combination of the two.
The possibility of secure digital money has unbridled potential for both those living under authoritarian regimes, as well as those seeking to escape them. While it may take decades to see Bitcoin cannibalise fiat currencies, it already has great potential as a contender to them. A monetary system operating in parallel to a state-enforced one redistributes the power from the incumbent issuer to the population, and dampens the effectiveness of the state printing press.

Russian Marketplace Allows Users to Sell Items Priced in Cryptocurrency
A new Russian online marketplace that allows users to buy and sell goods and services priced in cryptocurrency has rapidly expanded in recent months. The Mentalmarket website has been publishing a growing number of ads in a dozen categories, from “cryptoindustry” to “real estate.”

Audis Sold for Digital Coins
Mentalmarket looks like any other website with classified ads, but all of its items are priced in cryptocurrency. The platform supports payments in major coins such as bitcoin core (BTC), bitcoin cash (BCH), ether (ETH), litecoin (LTC), zcash (ZEC), Ripple’s XRP and dash. Prices are also displayed in U.S. dollars for convenience.
The marketplace has been gaining popularity among Russian crypto enthusiasts with a growing assortment of products and services. Users can buy almost anything — from mining hardware and bitcoin ATM devices to plots of land around Moscow and a hotel in Sochi. A farmer from Tashkent even sells sheep at 0.074 BTC a head.
An Audi dealer in Saint Petersburg, Russia’s second-largest city, recently posted a number of ads on Mentalmarket. “You can now buy any Audi model with cryptocurrency,” Kirill Skotnikov, Mentalmarket’s CFO, announced. Some of the more expensive models are selling for over 35 BTC, while an Audi A3 costs around 230 ETH.
Skotnikov is convinced that the limited number of everyday use cases is one of the reasons for the current downward trend on crypto markets and the bias against the technology. Quoted by the Russian news outlet Blockchain 24, he said:
Our mission is to make the daily use of cryptocurrency as familiar and simple as using bank cards by offering a wide range of goods and services and providing the infrastructure to simplify the interaction with cryptocurrencies for a large number of users.
How to Use Mentalmarket
Mentalmarket publishes ads from residents of the Russian Federation and other countries in the Commonwealth of Independent States (CIS). Users can log in to the platform if they have a Telegram account. They need to send “start” to @MentalMarket_Bot to request an authorization code, then click “Login via Telegram” on the Mentalmarket website before entering the code.
The online marketplace does not charge any fees when buyers and sellers contact each other directly on the platform. And users are not required to exchange their cryptocurrency to fiat money in order to make payments. In addition, the startup is currently developing a feature called “Secure Deals” to offer intermediation services. The parties to such deals would not need to meet or transact directly and would benefit from additional guarantees.
Mentalmarket also plans to introduce a rating system for all sellers. This would allow buyers to be more confident in the quality of the goods and services they purchase. Sellers, on the other hand, will be able to take advantage of the opportunity to build additional sales channels to reach a growing number of cryptocurrency users.
The platform has strict requirements regarding the content of the ads. Unlike darknet marketplaces, Mentalmarket does not facilitate the sale of any items that would be considered illegal in the countries in which it operates. The blacklist includes drugs, alcohol and tobacco products, as well as precious metals and databases with personal or corporate information.
Cryptocurrencies are not yet regulated in Russia and in most countries from the post-Soviet space. Nevertheless, their popularity has continued to increase in recent years. A number of platforms now offer exchange services to Russian speakers. And projects such as Mentalmarket are responding to growing demand for opportunities to spend digital money without converting to fiat.
