Ethereum Foundation pivots away from Poseidon in post-quantum plan
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.
