Regulating Decentralized Systems: Evidence from Sanctions on Tornado Cash
Blockchain-based systems are run by a decentralized network of participants and are designed to be censorship-resistant. We use sanctions imposed by the U.S. Department of Treasury on Tornado Cash (TC), a smart contract protocol, to study the impact and effectiveness of regulation in decentralized systems. We document an immediate and lasting impact on TC following the sanction announcement, measured by market reaction, transaction volume, and diversity of users. Still, net flows into TC contracts recover to and surpass pre-announcement levels for most pools, supporting viability of TC. ...

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 ...

A theory of transactions privacy
In this paper, we consider the costs and benefits of transactions privacy. In the environment we consider, privacy is the concealment of potentially useful information, but concealment also potentially bestows benefits. In some versions of the environment, the standard Coasian logic applies: given an unambiguous initial assignment of rights and sufficient flexibility in contracting, efficiency in information revelation will result. Coasian bargaining may be impeded, however, by either an inability to make certain commitments or by the presence of significant investments that must be made ...

Monetizing Privacy with Central Bank Digital Currencies
In prior research, we documented evidence suggesting that digital payment adoptions have accelerated as a result of the COVID-19 pandemic. While digitalization of payment activity improves data utilization by firms, it can also infringe upon consumers’ right to privacy. Drawing from a recent paper, this blog post explains how payment data acquired by firms impacts market structure and consumer welfare. Then, we discuss the implications of introducing a central bank digital currency (CBDC) that offers consumers a low-cost, privacy-preserving electronic means of payment—essentially, digital ...

COVID-19 and the Search for Digital Alternatives to Cash
Today, the majority of retail payments in the United States are digital. Practically all digital payments are tracked, collected, and aggregated by financial institutions, payment providers, and vendors. This trend has accelerated during the COVID-19 pandemic as payments that require physical contact, such as cash, have been discouraged. As cash gradually becomes obsolete, consumers are left with fewer alternatives for making private transactions. In this post, we outline some evidence on the impact of COVID-19 on consumer payment behavior and follow up in the second post in this Liberty ...
