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 ...

Defining Households That Are Underserved in Digital Payment Services
U.S. households that lack digital means of making and receiving payments cannot participate fully in an increasingly digitized economy. Assessing the scope of this problem and addressing it requires a definition of households that are underserved in digital payments. Traditional definitions of households underserved in the banking system—those that are unbanked and those that are underbanked—are not suitable because they do not account for the ownership of nonbank transaction accounts that can be used to make and receive digital payments. In this paper, we define households underserved in ...

What Makes Cryptocurrencies Different?
Permissionless blockchains, which support the most popular cryptocurrency networks like Bitcoin and Ethereum, have shown that it is possible to transfer value without relying on centralized trusted third parties, something that is new and remarkable (although perhaps most clearly useful for less developed financial markets). What makes permissionless blockchains able to transfer value without relying on a small number of trusted third parties is the combination of several components that all need to work together. The components themselves are not particularly new, but the combination of ...

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.

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.

Observations from the Retail CBDCs of the Caribbean
Three retail central bank digital currencies (rCBDCs) have been issued in the Caribbean, but thus far all have struggled to achieve expected adoption from both consumers and merchants. The efforts to launch these rCDBCs offer three takeaways: 1) the underlying technologies of rCBDCs may have little effect on adoption; 2) an rCBDC may need to demonstrate value added to entice consumers to use it; and 3) an rCBDC platform may need to be integrated into the larger financial ecosystem to be widely adopted.
