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 ...

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 ...
