Ethereum’s “Cat Herders,” a group of consultants reportedly responsible for “reviewing and finding an independent party” to carry out an audit on programmatic proof-of-work (ProgPoW), a new form of consensus algorithm for the Ethereum blockchain, have revealed how and why their team was assembled. In a Medium blog post published on March 25th by Jameson Hudson, an Ethereum developer and self-described “communicative programmer,” Ethereum’s Cat Herders explained that “due to the evolution of thinking that resulted in the delay in Ethereum’s move” from proof-of-work (PoW) to proof-of-stake (PoS)-based consensus, there seems to be a growing concern now that Ethereum’s current version of PoW, Ethash, might be “gameable.”
