PANews April 21, according to The Block, Ethereum co-founder Vitalik Buterin proposed on April 20 in the Ethereum Magicians forum to replace the Ethereum Virtual Machine (EVM) with the open-source instruction set architecture RISC-V to enhance the execution layer's efficiency. Buterin noted that this move could improve zero-knowledge proof efficiency by up to 100 times while maintaining bidirectional compatibility with existing EVM contracts. The proposal aims to address long-term scalability bottlenecks in Ethereum regarding data availability, block production competitiveness, and ZK-EVM proofs.
