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.

Beyond the Hype: An Introduction to Crypto Assets
Crypto assets have increasingly occupied news headlines and the minds of many consumers. While initially introduced as a payment system, crypto assets are seen by many as an enticing investment opportunity. This issue of Page One Economics® introduces crypto assets, blockchain technology, and the emerging crypto universe.

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.

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.

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 ...

Why Stablecoins Fail: An Economist’s Post-Mortem on Terra
Why do some stablecoins, such as Terra's UST, fail but others do not? Was Terra just an unlucky victim of a classic bank run or speculative attack? Or was its high-yield deposit offering doomed to fail like a Ponzi scheme? What is the limit of the stablecoin's algorithm? What makes payment stable? In this article, we'll dive into potential answers to these questions about the failed stablecoin.

Interoperability of Blockchain Systems and the Future of Payments
In a previous post, we introduced a three-pillar framework for interoperability of payment systems and discussed how technological, legal, and economic factors contribute to achieve interoperability and aid in the “singleness of money”—that payments and exchange are not subject to volatility in the value of the money itself—in the context of legacy systems. In this post, we use the framework to characterize the interoperability of blockchain systems and propose a methodology for evaluating interoperability. We show evidence of limited interoperability and draw insights for the future ...

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 ...

Beneath the Crypto Currents: The Hidden Effect of Crypto “Whales”
Cryptocurrency markets are often characterized by market manipulation or, at the very least, by a sharp distinction between large and sophisticated investors and small retail investors. While traditional assets often see a divergence in the success of institutional traders and retail traders, we find an even more pronounced difference regarding the holders of Ethereum (ETH), the second-largest cryptocurrency by volume. We see a significant difference in how large holders of ETH behave compared with smaller holders of ETH relative to price movements and the volatility of the cryptocurrency. We ...

How Censorship Resistant Are Decentralized Systems?
Public permissionless blockchains are designed to be censorship resistant, meaning access to the blockchain is unhampered. In practice, different blockchain ecosystem actors (such as users, builders, or proposers) can influence the degree to which a blockchain is resistant to censorship. In a recent Staff Report, we examine how sanctions imposed by the Office of Foreign Assets Control (OFAC) on Tornado Cash, a set of noncustodial cryptocurrency smart contracts on Ethereum, affected Tornado Cash and the broader Ethereum network. In this post, we summarize findings regarding sanction ...
