This project compares the security of Proof of Work (e.g., Bitcoin) versus Proof of Stake (e.g., Ethereum 2) protocols along several dimens…
In a Proof-of-Work blockchain the equilibrium hashrate is a monotone function of the fiat exchange value of the block reward. There is no l…
A principal vulnerability of a proof-of-work ("PoW") blockchain is that an attacker can re-write the history of transactions by forking a p…
