Many years of hard work went into the Poseidon family of hashes, and they have provided great real-world value on Ethereum and elsewhere and will continue to do so for several years. They are the reason why it's fast to generate a client-side SNARK for a modern privacy-protocol. The fact that we have ultra-fast general-purpose STARKs (mid-three-digit overhead for basically any batched computation) and may well soon drop to double-digit or even lower is more amazing than anything that we had been hoping for in the early 2020s. Big congratulations to all involved in Poseidon, and all involved in STARKs. https://firefly.social/post/x/2087905684180418733(vitalik.eth)
