According to researcher Justin Drake, advances in compact proof 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.
Thursday, Drake said The foundation abandoned Poseidon and turned to established alternatives like SHA or BLAKE. A hash function converts the data into a static digital fingerprint, enabling computers to check that the information has not been altered.
Poseidon was considered for future post-quantum systems such as leanVM, which would help Ethereum efficiently verify large volumes of blockchain activity. Those systems are not yet deployed on the mainnet.
