Ethereum Foundation Drops Poseidon From Post-Quantum Plan

Ethereum Foundation abandons Poseidon for post-quantum systems, adopting SHA/BLAKE with leanVM production-ready 2027. Established hashes mean fewer attack vectors and faster deployment; 2.5x proving speed gains enable practical quantum-resistant architecture at scale.

Ethereum Foundation moves away from Poseidon hash toward SHA and BLAKE

Ethereum Foundation switched from Poseidon to SHA-256/BLAKE3 after ZK systems improved enough to eliminate the algebraic hash's performance edge; preimage attack concerns sealed the shift. For tech leaders, this signals preference for battle-tested standards over novel cryptography when efficiency gains flatten—prioritizing compatibility and post-quantum security.
