Ethereum explores migration to Poseidon hash function ahead of Pectra upgrade

Vitalik Buterin called for researchers to join the Poseidon cryptographic analysis program while Ethereum explores the potential passage to the posted hash to improve its ZK resistant capacities.

In his Recent article on xVitalik Buterin, co-founder of Ethereum (Ethn), encouraged researchers to join the Cryptographic Analysis Program Poseidon. Vitalik plans to switch to the Happage of Poseidon to improve its operation ZK-ROVERS (Tools to verify private transactions). To help make this decision, Ethereum wants more information on Poseidon’s security, and they extended the deadline to request the financing program on March 15.

Strongly encourage researchers to participate in the cryptanalysis program poséidon.

We are seriously planning to migrate Ethereum to the hash posed of Poseidon to optimize ZK-Prover conviviality, so having more information on its safety properties is an extremely high value. https://t.co/ahbv8abd4z

In November 2022, a proposal called Ethereum improvement proposal (EIP) 5988 has been introduced, suggesting adding a precompiled contract to Ethereum virtual machine To implement the hash posted Happage, aimed at improving interoperability between EVM rollers and zero knowledge.

Since the introduction of the proposal, it seems that there has not been an official implementation or major update of the EIP 5988, but it seems that Ethereum is still seriously considering implementing Poseidon.

THE Haping of PoseidonIntroduced in 2019, is relatively new compared to well-established hash functions like SHA-256 and Keccak, which have existed for decades and have undergone in-depth tests. However, SHA-256 or Keccakt are not specifically designed for zero knowledge. On the other hand, Poseidon was specifically designed for use in zero knowledge of knowledge. Although it has not been as widely tested as Sha-256 and Keccak, Poseidon is already used in production in layer 2 systems on the Ethereum network and other blockchain projects.

Exploration by Ethereum of the Poseidon hash function is only a small part of its wider efforts to improve network performance. More particularly, the highly anticipated Pectra upgrade will be officially launched on April 8, aimed at improving the scalability of Ethereum, improving the abstraction of accounts, increasing the efficiency of the layer-2 and increasing validator awards. This upgrade follows the recent fork Dencun Hard – which was deployed in March 2024, significantly Reduction transaction fees For layer 2 networks.
