Southwest Economic system, Second Quarter 2022
Cryptocurrencies have existed for over 10 years. Since their launch, cryptocurrencies have grown in amount and market capitalization. As a result of they depend on decentralized know-how that’s computationally advanced, cryptocurrencies are vital vitality shoppers. Texas’ power-generating talents have captured the eye of cryptocurrencies as miners transfer to the state.
Cryptocurrencies have been round over a decade, with their valuations rising notably, although not all the time steadily. Cryptocurrencies are a type of digital foreign money that may function a medium of alternate and a retailer of worth, though they lack the backing of any central authority or authorities.
The market capitalization of bitcoin and ethereum—the 2 largest cryptocurrencies—totaled about $781 billion as of June 1 (Chart 1). All informed, there are about 100 vital cryptocurrencies, with a market capitalization of roughly $1.2 trillion, down 60 p.c from their current peak in fall 2021.
Cryptocurrency mining refers back to the work (completed by computer systems) that manages the blockchain, the document of cryptocurrency transactions. Crypto mining is controversial, partly, as a result of the method requires massive portions of electrical energy, which is commonly produced utilizing fossil fuels reminiscent of pure gasoline or coal. Furthermore, crypto mining is rising rapidly within the U.S. and in Texas, following current opposed regulatory and political developments in international facilities of crypto mining exercise—China, Russia and Kazakhstan.[1]
Mining exercise is measured by hash charge—a metric of the computational energy wanted for calculations to take care of the blockchain and earn new cryptocurrency cash. The bitcoin hash charge plummeted to zero in China in 2021 whereas rising within the U.S. and different nations (Chart 2).
Though dependable knowledge are laborious to come back by, some observers counsel Texas stands out as the largest state for crypto mining, accounting for 25 p.c of the U.S. whole.[2] Texas’ attraction stands out as the state’s comparatively cheap vitality and favorable rules.
A Digital Forex
Cryptocurrencies are supposed for use like another foreign money. However not like conventional bodily currencies such because the greenback, cryptocurrencies solely exist electronically.
A person can maintain crypto as a retailer of worth, an funding, and use it as collateral or as a method of cost. Digital cash may be “mined” or bought on an alternate and saved in a digital pockets.
Transactions through which a cryptocurrency is used are verified and recorded in a distributed public ledger—a database that’s unfold throughout a community of computer systems—the perfect identified of which is blockchain.
Transactions are saved in discrete blocks that taken collectively kind a series. Every block is a set of detailed knowledge, reminiscent of information or transactions. The blocks are iteratively linked in a series based mostly on a person block’s hash worth—a calculation based mostly on the info it holds relative to different such hyperlinks within the chain.
On this course of—which additionally serves as a safety measure—the hash worth of a earlier knowledge block determines the subsequent block’s hash worth, which is then used to find out the worth of the following block.
There are a number of causes for curiosity in cryptocurrencies. For some crypto fanatics, it derives from concern whether or not fiat currencies—just like the U.S. greenback and euro—are a dependable retailer of worth, particularly when the Federal Reserve and different central banks have expanded their steadiness sheets and put considerably extra foreign money in circulation following the World Monetary Disaster within the late 2000s and once more throughout the 2020–21 pandemic.
Therefore, some traders not solely purchase and maintain cryptocurrencies as a result of they imagine they are going to improve in worth but additionally as a result of they imagine cryptos might act as an inflation hedge, though that hasn’t been the case within the present high-inflation episode.[3] After all, others fear that with no authorities backing, cryptocurrencies’ worth will not be secured by any central authority and will collapse.
An extra attraction of cryptocurrencies is that the blockchain permits quick encrypted transaction processing and in methods that may embrace different transaction data, reminiscent of contract and counterparty particulars. This appeals to many shoppers and players, notably for many who transact throughout borders or want real-time funds.
Lastly, blockchain know-how permits for larger decentralization of finance as a result of it happens on a distributed ledger and isn’t managed by a authorities. Therefore, one other attraction of cryptocurrency is the unregulated and nameless nature of the transactions. Nevertheless, this characteristic doubtless attracts people who search to evade taxes, money-laundering legal guidelines or capital controls.
Transaction Prices, Pace
Cryptocurrencies can have excessive transaction prices and gradual pace, they usually carry the chance of manipulation. Whereas decentralized finance has the potential to cut back prices and speed up transactions (relative to conventional monetary methods), it doesn’t all the time ship.
Transaction prices are unstable and may rise sharply as transaction quantity will increase. Bitcoin transaction charges had been roughly $1.30 per transaction in June 2020, rose to $13.15 by October 2020 and exceeded $60 in April 2021.[4]
A current research famous {that a} doubtless cause for top charges is an absence of competitors in cryptocurrency markets, with its authors discovering that bitcoin mining capability is extremely concentrated—the highest 10 p.c of miners management 90 p.c of mining capability. Much more telling, simply 0.1 p.c of miners account for about 50 p.c of mining capability.[5]
A brand new cost protocol dubbed “lightning” was added to bitcoin in 2018 to extend pace and cut back transaction prices related to micropayments.[6] Lightning defers closing settlement on the bitcoin blockchain, although that opens a safety vulnerability that complicates tracing transactions.
Safety considerations heart on assaults on the blockchain. A 2020 research analyzed 14 assaults on 13 completely different cryptocurrencies the place the blockchain was manipulated by gaining management over 51 p.c of the mining nodes—computer systems looking for new items of cryptocurrency—to undermine the blockchain’s integrity.[7]
Keys to Crypto Mining
Cryptocurrency mining is the time period describing the computer systems that approve blocks of transactions to develop into a part of the blockchain. As compensation for sustaining the blockchain, miners obtain new cryptocurrency.
For instance, the compensation for mining one block of the bitcoin blockchain is 6.25 bitcoins, about $30,000 based mostly on the alternate charge as of June 1, 2022.[8] Provided that there are about 144 blocks mined day-after-day, miners collectively earn bitcoin price roughly $27 million each day.[9]
To take part, miners should clear up an advanced math downside, known as the “proof of labor.” Fixing this downside is gradual and vitality intensive, requiring vital quantities of computing energy, with no assure that the time and vitality expenditure will repay—solely the primary miner to resolve the proof of labor earns compensation.
Proof of labor is named a “consensus protocol”—a means through which consensus may be reached on adjustments to a blockchain. Though the proof-of-work consensus mechanism is basically efficient at permitting decentralization, it requires vital electrical energy.[10]
Critics argue that the method is wasteful; vitality could possibly be directed to extra productive makes use of, reminiscent of powering houses and companies.[11]
Power Economics
Mining and buying and selling of bitcoin consumes an estimated 91 terawatt hours yearly, equal to the annual nationwide vitality consumption of Finland or Jordan.[12] Mining a single block on the bitcoin blockchain consumes about 2,000 kilowatt hours, extra energy than a mean U.S. family consumes in two months.[13]
The traditionally low price of electrical energy in Texas relative to the nation and the state’s fast development of renewable vitality sources, in addition to gentle regulation, have doubtless helped appeal to crypto miners to the area.
What are the implications for Texas’ vitality sector? On the one hand, there are considerations that crypto mining energy demand can improve vitality prices, cut back electrical energy grid stability and result in larger carbon emissions.
Alternatively, crypto supporters say it’s doable that co-locating cryptocurrency mining with business renewable vitality technology may mitigate air pollution, enhance the economics of renewable tasks and appeal to traders.
This argument suggests crypto mining could possibly be a key supply of demand for renewable energy during times when electrical energy demand is low and energy output is excessive and storing the surplus electrical energy in batteries is impractical. Therefore, combining crypto mining with renewable tasks would supply extra constant, reliable electrical energy demand that might help renewable undertaking cashflows and enhance compensation prospects for windfarms and photo voltaic farms, for instance.[14]
The connection between cryptocurrency and vitality markets suggests extra analysis in regards to the markets’ relationships could also be applicable. For instance, relying on whether or not the value of bitcoin declines or will increase, the payout for mining diminishes or grows, assuming a relentless value for electrical energy. This rate-of-return calculation might have an effect on the willingness of miners to take part. Miner participation determines how rapidly new bitcoin involves {the marketplace}, affecting its liquidity and worth.
Moreover, the quantity of mining exercise might also immediate extra blockchain transactions, as some miners liquidate a part of their crypto earnings to pay for the prices of mining.
The rise in demand for vitality attributable to cryptocurrency mining is contingent on the continued use of the proof-of-work consensus protocol. The issue of mining new blocks on a proof-of-work blockchain will increase because the variety of miners rises. As considerations surrounding the vitality price for proof of labor have grown, some cryptocurrencies might evolve to much less energy-intensive consensus protocols.
Ethereum, the second-largest cryptocurrency, introduced plans to transform from proof of labor to proof of stake in late 2022. In proof-of-stake protocols, that are much less vitality intensive, miners function a validator in proportion to the quantity of the cryptocurrency they management.
Impression on Banks
Texas affirmed in June 2021 that state-chartered banks might supply custody companies for digital foreign money property. [15] The state has additionally stated banks can permit digital currencies as collateral for loans.[16] State officers additionally seem like responding to the safety challenges of “bodily” holding crypto, potential working difficulties at established crypto exchanges and a want to offer conventional monetary establishments an entrée to offering crypto custody and associated companies.[17]
Banks in search of to supply crypto companies should conduct an evaluation—figuring out and implementing controls to mitigate dangers, together with lack of consumer crypto property, risk-monitoring capability, money-laundering considerations and reputational threat.
Nonetheless, cryptocurrencies stay a novel improvement within the monetary companies ecosystem. As such, they could signify elevated threat to the monetary sector whereas concurrently providing innovation that holds the potential for long-term change.[18]

- China’s central financial institution banned all cryptocurrency transactions In September 2021; the Russian central financial institution proposed banning cryptocurrency in January 2022. Whereas this proposal was pending, the U.S. and European Union took measures in April to sanction Russian entities energetic in cryptocurrency in gentle of Russia’s warfare in opposition to Ukraine. In Kazakhstan, home vitality shortages resulted in a authorities crackdown on greater than 100 unlicensed crypto mining operations.
