Ethereum Foundation Drops Poseidon Hashing for SHA2 or BLAKE2
08-13
Ethereum Foundation abandons Poseidon hashing for SHA2/BLAKE2 at L1, citing SNARK design breakthroughs that allow traditional hashes to match performance in circuits.
Woofun AI reports that the Ethereum Foundation has ceased using the Poseidon hashing algorithm at the L1 layer, opting instead for SHA2 or BLAKE2. Researcher Justin Drake confirmed this pivot follows eight years of post-quantum cryptography research, noting that "binary field" SNARK advancements now allow traditional hashes to perform comparably to Poseidon.
This shift enables a single laptop to process approximately 1 million hash verifications per second. LeanVM is targeted for a 2027 launch, with full layer deployment expected by 2028.

Impact Assessment · Quick Read
The move away from Poseidon signals a maturation of SNARK technology, reducing reliance on specialized algorithms. By enabling standard hashes like SHA2 to function efficiently in circuits, the ecosystem may see lower implementation complexity and broader hardware compatibility. The 2027-2028 timeline for leanVM and layer deployments suggests a structured rollout of these post-quantum upgrades.
