Eggs in One Basket: Security and Convenience of Digital Currencies
Digital currencies store balances in anonymous electronic addresses. We analyze the trade-offs between safety and convenience of aggregating balances in addresses, electronic wallets and banks. In our model agents balance the risk of theft of a large account with the cost to safeguarding a large number of passwords of many small accounts. Account custodians (banks, wallets and other payment service providers) have different objectives and tradeoffs on these dimensions; we analyze the welfare effects of differing industry structures and interdependencies, and in particular the consequences ...

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 Future of Payments Is Not Stablecoins
Stablecoins, which we define as digital assets used as a medium of exchange that are purported to be backed by assets held specifically for that purpose, have grown considerably in the last two years. They rose from a market capitalization of $5.7 billion on December 1, 2019, to $155.6 billion on January 21, 2022. Moreover, a market that was once dominated by a single stablecoin—Tether (USDT)—now boasts five stablecoins with valuations over $1 billion (as of January 21, 2022; data about the supply of stablecoins can be found here). Analysts have started to pay increased attention to the ...
Briefing
A Historical Perspective on Digital Currencies
This article reviews private currencies in U.S. history to shed light on the contemporary issue of digital currencies. This perspective suggests that government interventions have a critical role in creating a well-functioning money and payments system. Particularly, a central bank digital currency (CBDC) can be a useful tool to supplement regulation in addressing long-standing concerns and risks associated with private currencies.
