Casper's performance under different validator strategies

Ádám Antal, Tamás Király



Abstract

Casper is a proof-of-stake-based finality system for blockchains, introduced by Buterin and Griffith. The protocol features a set of validators, who cast votes in the distributed system with the aim of collectively choosing a unique chain, whereas the block generation itself is proof-of-work based. The votes must adhere to some simple rules, but otherwise can be arbitrary. We analyze the behavior of the protocol, when the validators follow different strategies, and examine the impact on the stability of the blockchain.
