Ethereum co-founder Vitalik Buterin is advocating for deeper research into the Poseidon hash function as the network explores ways to improve zero-knowledge (ZK) proof efficiency.
In a Feb. 26 post on X, Buterin encouraged cryptographers to participate in a security analysis program for Poseidon while quoting a message that extended the funding application deadline to March 15.
He stated:
“We are seriously considering migrating Ethereum to the Poseidon hash to optimize zk-prover friendliness, so having more information about its security properties is extremely high value.”
What is Poseidon?
Poseidon is a cryptographic hash function designed specifically for zero-knowledge applications.
Unlike traditional hash functions such as SHA-256, Poseidon is optimized for zero-knowledge (ZK) proofs, a cryptographic technique that allows transactions to be verified without revealing sensitive details.
ZK proofs are becoming increasingly crucial in Ethereum’s scaling efforts, particularly
