At the July 26, 2023 meeting of the Bank of England's (BoE's) CBDC Technology Forum Tom Mutton (Chair) explained that they were now at the start of the design phase of the digital pound roadmap, during which they would conduct experiments and proofs of concept, and develop a detailed blueprint. He noted that the design phase was expected to last for 2-3 years, after which a decision would be made on whether or not to proceed to the build phase, during which the Technology Forum is expected to provide ideas and expert analysis that could inform and challenge the Bank of England's experiments and the eventual digital pound blueprint.

The Bank of England is recruiting for Solution Architects within the Technology team of its Central Bank Digital Currency (CBDC) Unit. The CBDC Unit is responsible for analyzing the opportunities and challenges presented by CBDC and developing the design of a CBDC. The Unit's activities include macroeconomic analysis, work on functional design, exploration of technology options, and engaging private-sector and international counterparts. The responsibility of the job holder will be to explore the technology design and architecture options for a potential retail CBDC.

"Bitcoin is a "Money Over Internet Protocol," as is Ethereum, potentially. Just as VOIP moves voice data around the internet natively, Bitcoin and Ethereum move value data around the internet natively. Most people disparage Bitcoin, Ethereum, et al. as protocols that can't scale and can't possibly threaten the incumbent financial industry, just as they denigrated VOIP. But the scaling technology is now here - it's called the Lightning Network, which is a Bitcoin layer 2 protocol. Its throughput capacity roughly equals that of Visa, and payments made over Lightning cost virtually zero. There are other scaling technologies, too. If I'm right and scaling technologies for internet-native money protocols have arrived, then many legacy systems operating in the financial system today will be obsolete within a handful of years."

"This World Bank note examines the implications of digital innovation for market structure and attendant policies, including financial and competition regulation. There have been several surveys of regulatory responses. This note takes a step back, to look at what the economic theory of banking and financial intermediation can tell us about how technology may drive industrial organization in the sector, and how that might inform further policy responses. The paper roots the impact of the digital transformation of finance in innovations that have enabled providers to address long-standing challenges of financial intermediation, including asymmetric information, uncertainty, incomplete markets, and fixed and variable costs of production. The paper describes how digital innovation affects these key economic frictions in finance and alters the financial services value chain and industrial organization. The forces driving these changes, and potential outcomes in terms of industry structure, lead to insights for policy makers on how to harness the benefits of fintech, while mitigating some of the risks, particularly around competition and market structure. The focus is on economic and technological forces that apply broadly across financial services. It recognizes that the sector encompasses a wide range of different products and services and is composed of numerous sub-markets that might use different technologies or have different economic structures. These may thus diverge in market structure and competition outcomes."

The Bank of England is proposing a limit of between £10,000 and £20,000 per individual as the appropriate balance between managing risks and supporting wide usability of the digital pound. The Technology Working Paper accompanying the Consultation Paper sets out an illustrative and complementary conceptual model consisting of a core ledger, API layer, analytics and alias service. The core ledger operated by the Bank might be centralised, running as a traditional database, or it might use Distributed Ledger Technology (whether a blockchain or another form of the technology). The Bank would provide the digital pound and the central infrastructure, including the 'core ledger'. Private sector firms - which could be banks or approved non-bank firms - would provide the interface between the Bank's central infrastructure and users by offering wallets and payment services. These private companies would be able to integrate the digital pound, as the settlement asset, into the services they would offer to wallet holders. The wallets would be operated on a 'pass-through' basis. That is to say, they would not constitute a claim on the wallet provider in the way that a bank account is a claim on a bank. Nor would they represent a custody arrangement. Rather, the wallets would hold all of the customer related information and 'pass-through' the customers instructions to the Bank's infrastructure. All of the digital pounds would be held on the Bank of England's central ledger.

The IMF published a working paper that presents a vision for a multilateral platform that could improve cross-border payments, as well as related FX transactions, risk sharing, and more generally, financial contracting. It proposes a design that centralizes payments and settlement and that integrates functionality needed for cross-border transactions: streamlining compliance, reducing the cost of FX conversion, and better managing financial risks. The paper also shows how new technologies can be leveraged to better organize payments and associated financial markets. These new technologies are ledgers with unique states, programmability that allows for smart contracts, and encryption which ensures privacy, and can alleviate the underlying obstacles to trade. These technologies allow the design of a multilateral exchange system where participants can truthfully share information with smart contracts but can retain privacy relative to other parties.

"The Bank of England presented a summary of the Consultation Paper and the accompanying Technology Working Paper, published on 7 February 2023. The presentation covered the proposed distribution model, technology design considerations and conceptual architecture for a UK CBDC, called the digital pound."

China's National Blockchain Technology Innovation Center officially started its work, collaborating with local universities, think tanks and blockchain businesses to develop blockchain technology in China. It will reportedly train more than 500,000 specialists in distributed ledger technology (DLT). The center's mission is to connect various blockchain use cases in the country into a single cohesive network.

"This analysis shows that permissioned and private ledgers form a subclass of Distributed Ledger Technologies (DLT), which are distinguished from the original blockchain. DLTs operate with databases known as "ledgers," copies of which are distributed among multiple nodes, but not anyone can create and validate new blocks of data in such a ledger; they are not decentralized. On the contrary, blockchain was designed as a decentralized, open, and competitive peer-to-peer system. The widespread misconception is to call any technology "blockchain" when it has some chunks of data connected through cryptographic hashes. The technology of creating a sequence of timestamped records connected with hashes is not new, it was designed in the early 90s, but nobody has ever called it "blockchain," as it has never dealt with decentralized consensus protocols and did not operate in a distributed network. Hence, not every chain of blocks is the blockchain. The paper dives into the details of various of DLTs and blockchains. It aims to bring rigor into terminology and academic discourse. It also raises the alarm on false expectations that may appear across industries and the public about a decentralization effect that some DLTs might not bring."

The Financial Services and Markets Bill 2022 has been introduced into the U.K. Parliament. Section 22 of the Bill contains a new power for the government to introduce bespoke rules on the regulation of payments, payment systems and service providers in relation to the payments that include "digital settlement assets", which includes any digital representation of value or rights that "(a) can be used for the settlement of payment obligations; (b) can be transferred, stored or traded electronically, and (c) uses technology supporting the recording or storage of data (which may include distributed ledger technology)." The Chancellor of the Exchequer said that HM Treasury will be working to understand how distributed ledger technology could be applied to a U.K. sovereign debt instrument.

Legislation to "combat China, prevent cyberattacks, and protect U.S. intellectual property" was introduced into the U.S. House of Representatives. The Creating Legal Accountability for Rogue Innovators and Technology (CLARITY) Act would prohibit the federal government from utilizing blockchain technology developed by China and other foreign adversaries to ensure these countries do not have a backdoor to access critical national security intelligence and Americans' private information. Firms listed include any parent companies or subsidiaries of China's Blockchain Services Network (BSN) and the affiliated Red Date Technology, and iFinex, the parent company of USDT issuer Tether.

The Centre for Information Policy Leadership at Hunton Andrews Kurth LLP released a white paper on privacy-enhancing and privacy-preserving technologies. The paper explores how organizations are approaching privacy-enhancing technologies ("PETs") and how PETs can advance data protection principles and provides examples of how specific types of PETs work. It also explores potential challenges to the use of PETs and possible solutions to those challenges.

"Representations about deposit insurance may be particularly relevant with respect to new financial products or services, especially those involving new technologies such as digital assets, including crypto-assets. New technologies may yield significant benefits for consumers, workers, and small businesses. Nonetheless, especially with respect to new technologies, some market participants may seek to entice consumers to use their products or services by deceptively advertising that uninsured products or services are FDIC-insured. These misrepresentations disadvantage financial institutions that truthfully market FDIC-insured accounts to consumers. Such misrepresentations also harm consumers, who may find that their assets are not insured in a time of financial distress."

Amazon Web Services (AWS) published Retail Central Bank Digital Currency: From Vision to Design, which outlines a framework that can help support policymakers in evaluating the interdependencies between central bank digital currency (CBDC) policy and technology choices. In a blog post, they summarized the key principles outlined in paper (see below). "The CBDC strategy framework starts with a central bank's policy goals and aligns those to design principles to create awareness of potential policy trade-offs. Then, the solution exploration phase aligns technology considerations to those principles, and competitive dynamics from the design are considered. Results from experimentation then feed back into design principles to make sure the technical solution aligns to policy goals."

The Central Bank of Nigeria (CBN) is in talks with potential technology partners to develop a new system to run and manage its eNaira central bank digital currency (CBDC). The CBN wants to develop its own CBDC software so that it can keep full control of the underlying technology. The CBN, in collaboration with Bermuda-based Bitt inc., launched the eNaira in October 2021 which, like other CBDC pilots and launches, has struggled to win wide adoption, although not necessarily because of the technology platform.

The National Bank of Georgia (NBG) is inviting fintech companies to express interest in participating in its digital lari central bank digital currency (CBDC). In April 2021, NBG launched the first stage of the project and invited interested financial technology providers to participate. Now the NBG will select a technological partner based on information provided by the companies, including the CBDC system, technical capabilities, security, and technological proposal for the pilot project. The deadline for submissions is February 15, 2023.

Central Bank of the Republic of Turkey (CBRT) provided an update on the proof-of-concept phase of its Digital Turkish Lira Project. Payment transactions were successfully executed on the Digital Turkish Lira Network, and in the first quarter of 2023, closed-circuit tests will be carried out with technology stakeholders. The findings obtained from the tests will be shared with the public in a comprehensive evaluation report. The tests will then be expanded later in 2023 to include selected banks and financial technology companies, followed by broad participation pilot tests. Tests will include checking out how the distributed ledger technology (DLT) based platform will integrate with existing payment ecosystems. Also, throughout 2023, priority will be given to the legal framework and building out digital identification infrastructure.

The Registration Authority of the Abu Dhabi Global Market (ADGM) issued a consultation paper to explain the proposed Distributed Ledger Technology Foundations Regulations 2023, and seeking public feedback  on the proposed new legislative framework for foundations that facilitate Distributed Ledger Technology (DLT) and token issuance. The ADGM is an international finance center within the United Arab Emirates (UAE) and has a bespoke licensing regime for virtual asset service providers supervised by its financial regulator. The authority is not the ADGM's financial watchdog, so the proposal is limited to tackling matters of service type and governance.

The UK Technology Working Group published a report builds on its first report published in November 2023, and expands the potential use cases of fund tokenisation first highlighted in that initial report. In particular, the report explores the use of tokens as collateral for money market funds, and the role tokenised funds play in a fully "on chain" investment market that will streamline back-office functionality. [First report: https://www.gov.uk/government/news/technology-working-group-publishes-report-on-fund-tokenisation]

The Bank of England (BoE) and U.K. Financial Conduct Authority published a consultation paper proposing to implement and operate a Digital Securities Sandbox (DSS). The DSS will allow firms to use developing technology, such as distributed ledger technology (DLT), in the issuance, trading and settlement of securities such as shares and bonds. Firms that successfully apply for the DSS will be able to operate under a set of rules and regulations that has been modified to facilitate this. The DSS lasts for five years and will help regulators design a permanent technology friendly regime for the securities market.
