7、Blockchain, and Cryptocurrency Trends Cryptocurrencies and their underlying blockchain technology have the potential to fundamentally impact the financial sector.3 Blockchain, as a form of DLT, offers many potential benefits to financial institutions (FIs) including lower costs, improved transparenc

8、y, and operational auditability. More specifically, blockchain creates a shared ledger that can reduce the duplication of information that occurs across FIs and intermediaries when they maintain their own databases and ledgers. New technology startups are building services and businesses with blockc

9、hain, similar to how technology disruptors Amazon, Google, Facebook and Uber built software platforms and successful businesses through the connectivity provided by internet standards. However, blockchain developments remain nascent as these new businesses contend with U.S. regulatory challenges and

10、 becoming more secure and trustworthy systems. The success of cryptocurrencies and blockchain technology is contingent upon how trustworthy these solutions become, beyond the basic security of the distributed ledgers. Law, regulation, and governance support trustworthy systems that can lead to broad

11、 adoption. Providers need to address legitimate government concerns and build confidence in new blockchain systems through transparency about how the processes work, what the benefits are, and develop straightforward solutions that secure adoption.4 A distributed ledger is a decentralized digital sy

12、stem (i.e., distributed across several computers or nodes) that operates a set of synchronized ledgers that are shared by multiple entities (i.e., no central authority or data store). DLT records the transaction of assets and their details in multiple places simultaneously. Unlike traditional databa

13、ses, distributed ledgers do not require a central data store or administration functionality.5 Instead, multiple nodes are responsible for updating the ledger or transactions if any data changes occur, and every node receives its own copy of the ledger.6 Blockchain is a type of distributed ledger sy

14、stem where various transactions (i.e., not only monetary) between parties are recorded redundantly and securely in multiple databases. A blockchain organizes data or records into blocks linked with each other and encrypted, using strict security protocols that require computational trust.7 A block c

15、ontains details such as the transaction timestamp and a link to the previous block, making it impossible to alter information about the records retrospectively. Unlike traditional databases, a blockchain allows only adding new data; existing data cannot be altered or deleted. Blockchains are useful

16、for financial transactions because they help to reduce operational inefficiencies 3 Not all cryptocurrencies use a blockchain (e.g., IOTA). 4 How Blockchain will impact the financial sector.

17、uld reduce the traditional reliance on a central ledger used in financial markets and managed by a trusted entity, which could change how assets are stored or maintained, obligations discharged, contracts enforced, and risks managed. 6 Every time a new transaction is added, it is encrypted and all t

18、he copies of the ledger are updated before being added to the ledger. 7 In information security, computational trust is the generation of trusted authorities or user trust through cryptography. In centralized systems, security is typically based on the authenticated identity of external parties. 3 (

19、leading to cost savings), provide greater security based on a decentralized system, and are immutable. Examples include Hyperledger,8 Ethereum,9 Quorum,10 and R3.11 Cryptocurrency is a digital currency that serves as a unit of account or store of value. Traditionally, it did not meet the standard fo

20、r a medium of exchange because of price volatility and lack of inherent value. The recent advent of stablecoins, which peg a cryptocurrency against a stable asset (e.g., fiat currency), has helped address some of these issues. Cryptocurrency uses cryptographical functions to conduct financial transa

21、ctions (i.e., use of private and public keys directly between two parties). These transfers can be done with minimal processing fees and leverage blockchain technology to gain decentralization, transparency, and immutability. U.S. Federal and State Government DLT and Digital Asset Initiatives The fi

22、rst panel12 discussed DLT, blockchain, and cryptocurrency trends in the U.S. at the federal and state levels. Paul Thanos, U.S. Department of Commerce (DoC), reviewed the role of technology in changing international trade and efforts to adopt DLT. Chris Rothfuss and Tyler Lindholm, co-chairs of the

23、Wyoming Blockchain Task Force (the “Task Force”), explained the State of Wyomings governance model for blockchain and cryptocurrency business development and how it was an opportunity for its technology sector. U.S. Department of Commerce Office of Finance and Insurance Industries (OFII) Within the

24、DoC, the OFII focuses on blockchain technology to understand its impact on innovation, U.S. economic competitiveness, and international trade.13 Now that companies are at the adoption stage of blockchain and DLT, one of OFIIs objectives is to identify a series of trade and business use cases includi

25、ng trade finance, governance, insurance, and supply chain management. The Office develops programs and policies to highlight the business impact of blockchain and DLT solutions, identifies impediments to its adoption, and, when appropriate, delineates U.S. trade policy priorities that can facilitate

26、 blockchain solutions. OFII is also closely tracking how various foreign governments are pursuing national blockchain strategies. DoC is also supporting DLT initiatives that use blockchain to expedite engagement by small/medium U.S. businesses (SMBs) in international trade through collaboration with

27、 industry on private sector solutions that expand access to trade finance. DoC also organizes meeting between U.S. businesses and foreign governments to develop business opportunities (e.g., attending the Singapore FinTech festival). 8 Hyperledger is an open source collaboration to advance cross-ind

28、ustry blockchain technologies. See https:/www.hyperledger.org. 9 Ethereum is a global, open-source platform for decentralized applications.

31、vices industries, focusing on policy, promotion, and analysis to expand U.S. financial services exports, attract investment to the U.S., and facilitate the growth and development of new and inclusive segments of finance. 4 OFII is involved in several activities focused on DLT and blockchain includin

32、g strategic partnerships with Georgetowns Center for Financial Markets and blockchain businesses ConsenSys14 and BurstIQ15 and public outreach to provide information about blockchain to the marketplace. OFII is currently exploring collaboration with a financial regulatory agency to develop a toolkit

33、 that explains blockchain, its applicability to U.S. businesses, and its importance in a global context. The toolkit will help companies understand how to leverage DLT solutions for innovation. The DoC does not have a regulatory role nor promote the use of cryptocurrency, but seeks to understand its

34、 adoption and commercial application globally and any relevance to U.S. competitiveness. According to Mr. Thanos, less than 1 percent of U.S. FIs use cryptocurrency as an asset, which the Securities and Exchange Commission (SEC) permits under the “qualified custodianship rule.”16 State of Wyoming Le

35、gal Framework for Digital Assets and Blockchain The State of Wyoming is effective because it listens to the industry. Legislators Rothfuss and Lindholm recognized Wyoming government could play a greater role in digital assets, blockchain, and cryptocurrencies. Through their legislative efforts, Wyom

36、ing has been innovative and supported and promoted a legal framework for these new systems. Wyomings Blockchain Task Force has offered a global forum to stakeholders seeking a rational governance model that includes definitions and a legal framework to reduce uncertainty and risk in the marketplace.

37、 It has also provided consumer protection and market fairness rules for digital assets. Wyoming has passed 13 blockchain and crypto-related legislative bills to create the states legal framework, and several other laws were passed in the 2020 legislative session. Changes include reclassifying digita

38、l assets as property under the Wyoming Uniform Commercial Code (UCC) and establishing special-purpose depository institutions (SPDIs) to support businesses that cannot secure traditional banking access, such as those within blockchain industries.17 Fully-reserved fiat banks18 can apply to be designa

39、ted as an SPDI, which allows them to become custodians for crypto-assets.19 14 ConsenSys is building Ethereum blockchain infrastructure and applications for new economic systems that are more open, efficient, and secure. See . 15 BurstIQ is a blockchain enablement company, offering enterprise-level

40、blockchain solutions for the health and healthcare industry. See 16 The SEC adopted amendments to conform the custody rule under the Investment Advisers Act of 1940 to modern custodial practices and require advisers that have custody of client funds or securities to maintain those assets with broker

41、-dealers, banks, or other qualified custodians. See https:/www.sec.gov/rules/final/ia-2176.htm. Some U.S. FIs that work with crypto-assets include Ally, Goldman Sachs, USAA, and Simple Bank. 17These Special Purpose Depository Institutions (SPDIs) will be required to have 100 percent reserves, cannot

42、 lend, will be for business depositors only, and will not be required to have FDIC insurance. The Wyoming Division of Banking will be the primary regulator. 18 Fiat currency is legal tender whose value is backed by the government that issued it. The U.S. dollar is fiat money. 19 A 2016 Board of Gove

45、 5 According to the legislators, several new “blockchain banks” could bring over $20 billion in assets to Wyoming by the summer of 2020 and contribute an estimated $4 million in tax revenues.20 Avanti Bank and Trust will be the first applicant to receive the SPDI charter and is expected to open in 2

46、021.21 While the panel did not discuss blockchain or DLT in the context of traditional mobile/digital payments, there is relevance for future MPIW discussions. Blockchain could add a layer of security and trust to mobile and digital wallets and mobile P2P transactions because of its ability to carry

47、 a ledger of encrypted data with details of prior transactions. Every individual in the blockchain-enabled transaction would have a record of relevant transactions in the system, making it possible to transfer money with an inherent trust factor, with added protection that the transaction cannot be

48、altered, and is available for everyone to review. II. Cryptocurrency, Stablecoins, and Central Bank Digital Currency Cryptocurrencies are disruptive and prone to price volatility, making some merchants reluctant to adopt them. In comparison, stablecoins can potentially serve as the backbone of finan

49、cial applications on the blockchain. A stablecoin is a cryptocurrency that pegs its market value to a stable reference, such as the U.S. dollar, or the price of a commodity, such as gold. To achieve global acceptance, it would have to be private, decentralized, price stable, and scalable. Stablecoins also face legislative, compliance, and licensing challenges. Some
