Embedded Supervision: How to Build Regulation into Blockchain Finance
The spread of distributed ledger technology (DLT) in finance could help to improve the efficiency and quality of supervision. This paper makes the case for embedded supervision, i.e., a regulatory framework that provides for compliance in tokenized markets to be automatically monitored by reading the market?s ledger, thus reducing the need for firms to actively collect, verify and deliver data. After sketching out a design for such schemes, the paper explores the conditions under which distributed ledger data might be used to monitor compliance. To this end, a decentralized market is modelled ...

The Blockchain Revolution: Decoding Digital Currencies
Cryptocurrencies and decentralized finance have grown considerably since the publication of the white paper on bitcoin in 2009. This article presents an overview of cryptocurrencies, blockchain technology, and their applications, explaining the spirit of the enterprise and how it compares with traditional operations. We discuss money, digital money, and payments; cryptocurrencies, blockchain, and the double-spending problem of digital money; decentralized finance; and central bank digital currency.

A Survey of Fintech Research and Policy Discussion
The intersection of finance and technology, known as fintech, has resulted in the dramatic growth of innovations and has changed the entire financial landscape. While fintech has a critical role to play in democratizing credit access to the unbanked and thin-file consumers around the globe, those consumers who are currently well served also turn to fintech for faster services and greater transparency. Fintech, particularly the blockchain, has the potential to be disruptive to financial systems and intermediation. Our aim in this paper is to provide a comprehensive fintech literature survey ...

Decentralized Finance (DeFi): Transformative Potential and Associated Risks
Financial services in the crypto finance world are provided by a combination of centralized finance (CeFi) organizations and decentralized finance (DeFi). CeFi's are roughly similar to traditional financial intermediaries, but DeFi seeks to provide services using smart contracts (computer code) rather than an intermediary. DeFi's unusual structure creates some interesting potential but also raises new risks in addition to those already inherent in blockchains and crypto finance. This paper reviews some of the opportunities and risks.

Beyond the Doomsday Economics of “Proof-of-Work” in Cryptocurrencies
This paper discusses the economics of how Bitcoin achieves data immutability, and thus payment finality, via costly computations, i.e., ?proof-of-work.? Further, it explores what the future might hold for cryptocurrencies modelled on this type of consensus algorithm. The conclusions are, first, that Bitcoin counterfeiting via ?double-spending? attacks is inherently profitable, making payment finality based on proof-of-work extremely expensive. Second, the transaction market cannot generate an adequate level of ?mining? income via fees as users free-ride on the fees of other transactions in a ...

The Lightning Network: Turning Bitcoin into Money
The Lightning Network (LN) is a means of netting Bitcoin payments outside the blockchain. We find a significant association between LN adoption and reduced blockchain congestion, suggesting that the LN has helped improve the efficiency of Bitcoin as a means of payment. This improvement cannot be explained by other factors, such as changes in demand or the adoption of SegWit. We find mixed evidence on whether increased centralization in the Lightning Network has improved its efficiency. Our findings have implications for the future of cryptocurrencies as a means of payment and their ...

An Introduction to Web3 with Implications for Financial Services
Web3 is used to describe the next iteration of the internet in which decentralized services are automated on blockchains. This paper describes the elements of Web3 including blockchains and tokens. It describes the largest decentralized finance protocols and some specific services where blockchain and tokens can be used. The paper concludes with a brief discussion of some regulatory challenges.

Tornado Cash and Blockchain Privacy: A Primer for Economists and Policymakers
This article explores non-custodial crypto asset mixers such as Tornado Cash. We analyze what types of mixers exist and how they work. We discuss opportunities and risks and offer an approach, based on voluntary disclosure, that would allow financial market regulators to combat money laundering and illicit activities, while allowing honest users to interact with privacy-enhancing protocols. We explain how crypto asset mixers play an important role on public blockchains and that privacy may be difficult to attain without them.
