Ethereum L1 abandons the Poseidon hash scheme and switches to SHA/BLAKE. Researcher at the Ethereum Foundation, Justin Drake, recently disclosed that the EF will no longer pursue Poseidon as Ethereum L1’s hash scheme, and instead will adopt traditional hash functions such as SHA or BLAKE. Recent breakthroughs in binary-field-based SNARK designs have enabled traditional hash functions like SHA2 and BLAKE2s to achieve performance comparable to Poseidon within SNARKs as well, simplifying Ethereum’s cryptographic dependencies and laying the groundwork for a post-quantum cryptography roadmap. The current roadmap aims to achieve production-grade leanVM in 2027, and in 2028 move forward with deployment of the consensus layer, data layer, and execution layer. $ETH #以太坊 # Blockchain
