Advances in compact proofs have erased Poseidon’s previous performance advantage, according to researcher Justin Drake.
The Ethereum Foundation is moving away from the Poseidon hash function in its planned post-quantum architecture, according to researcher Justin Drake.
On Thursday, Drake said the foundation was abandoning Poseidon and turning to established alternatives such as SHA or BLAKE. A hash function converts data into a fixed digital fingerprint, enabling computers to check that information has not been altered.
Poseidon had been considered for future post-quantum systems such as leanVM, which would help Ethereum efficiently verify large volumes of blockchain activity. Those systems have not yet been deployed on mainnet.
