Vitalik Buterin, co-founder of Ethereum, has proposed a significant overhaul for the Ethereum execution layer by replacing the current Ethereum Virtual Machine (EVM) with the open-source RISC-V architecture. This transition aims to greatly enhance the efficiency of the network’s execution layer and address major scaling challenges. The EVM has been a critical component of Ethereum’s design, enabling seamless connectivity with non-Ethereum networks and facilitating smoother transitions for developers creating applications. Buterin advocates that the RISC-V architecture could potentially offer efficiency gains of over 100x, particularly for specific applications, which would help in reducing transaction costs—a barrier to adoption. Additionally, RISC-V's built-in support for certain encryption methods may simplify the transition compared to the community's alternate plans involving zero-knowledge cryptography. This proposal arrives amidst a period of reflection within the Ethereum community, where declining transaction volumes and a leadership transition in the Ethereum Foundation have sparked concerns about the ecosystem's clarity and competitive edge against rival blockchains.
