Proud that Flock is part of this milestone for Ethereum's future. Until recently, proving standard hash functions was too slow for Ethereum blocks, so cryptographers instead built bespoke SNARK-friendly hashes. Flock — developed by @ronrothblum, @benediktbuenz, and @kleptographic — closes that gap, moving us closer to a future where proving is as fast as computing. Our work with @eigenlabs and @yukonresearch on the autoresearch competition has crossed 1.8M BLAKE3/sec proven on an M3 Max. This cutting-edge performance enables Ethereum to switch to hash functions that have withstood decades of scrutiny, a record their newer SNARK-friendly counterparts haven't had time to build. We are entering a golden era of hash-based cryptography, just in time for the post-quantum transition.
