Vitalik Buterin Proposes Replacing Ethereum EVM with RISC-V for Future Scaling

• Vitalik Buterin suggests replacing Ethereum’s EVM with the RISC-V architecture
• The change would enhance efficiency and simplify Ethereum’s execution layer
• Developers could continue using Solidity and Vyper with minimal disruption

Ethereum co-founder Vitalik Buterin has proposed a major shift for the blockchain’s execution layer: gradually replacing the Ethereum Virtual Machine (EVM) with RISC-V architecture. 

Starting with dual VM support, the goal is improved scalability, prover efficiency, and overall execution simplicity for Ethereum.

Outlined on the Ethereum Magicians forum, Buterin called this a long-term scaling solution: swapping the EVM (smart contract runtime) for RISC-V (a hardware instruction set).

While the shift is technically complex, the design preserves key Ethereum features. Developers would still interact with familiar tools and abstractions like accounts, storage, and contract calls. Existing contracts written in Solidity or Vyper would remain compatible, with these languages integrating RISC-V as a backend.
