Vitalik Buterin praises years of Poseidon hash research, saying it made client-side SNARK generation fast for modern Ethereum privacy protocols

Buterin credits the Poseidon hash family with making client-side SNARK generation fast for modern privacy protocols, saying years of work on it delivered real-world value on Ethereum and beyond, with benefits expected to continue for several years. He also highlights ultra-fast general-purpose STARKs, currently at mid-three-digit overhead for essentially any batched computation, with potential to drop to double-digit or lower — exceeding early-2020s expectations. He congratulated everyone involved in Poseidon and STARKs research.
