On April 20, Vitalik Buterin proposed replacing the existing EVM language with the RISC-V instruction set architecture to enhance the speed and zero-knowledge functionality efficiency of the Ethereum execution layer. He pointed out that this is the 'only viable path' to achieve optimizations similar to those between the execution layer and the consensus layer. The proposal aims to address Ethereum's bottlenecks in throughput and competition with new blockchains like Solana. Buterin estimates that this move could bring up to a 100-fold increase in efficiency.$ETH
