Ethereum developers are advancing a cryptanalysis program for Poseidon2, identifying security issues that could be addressed by adding extra rounds or reverting to Poseidon1. Instead of committing to a single version with a precompile, which could lead to complexity and consensus risks, Ethereum is exploring a flexible approach. This involves a precompile capable of performing vector math over 32-bit numbers, significantly boosting efficiency by reducing gas costs and control flow overhead. This innovation aims to simplify the implementation of various Poseidon versions and enhance operations in quantum-resistant signatures and fully homomorphic encryption, effectively acting as "the GPU for the EVM."
