In a groundbreaking proposal, Vitalik Buterin has suggested a radical transformation of Ethereum by replacing its Ethereum Virtual Machine (EVM) with the RISC-V architecture. This shift aims to tackle the pressing issues of scalability and efficiency that have plagued Ethereum, especially as it faces stiff competition from emerging blockchains like Solana and Sui. Buterin's vision, unveiled on April 20, 2025, seeks to enhance Ethereum's execution layer, potentially revolutionizing the way smart contracts are executed and paving the way for a more robust decentralized ecosystem.

• RISC-V could improve Ethereum's efficiency by up to 100 times, addressing scalability bottlenecks.
• The proposal aims to simplify the consensus layer and enhance overall network performance.
• Mixed reactions from the Ethereum community highlight the urgency for innovative solutions amid declining transaction fees and user activity.

The Ethereum ecosystem has long relied on the EVM to execute smart contracts, but as the blockchain landscape evolves, the limitations of the EVM have become increasingly apparent. With transaction fees dropping to an average of $0.16— the lowest since 2020— and user activity waning, Ethereum's competitive edge is at risk. Buterin's proposal to adopt RISC-V, an open standard instruction set architecture, is seen as a potential game-changer. Known for its flexibility and efficiency, RISC-V could significantly enhance Ethereum's scalability, allowing for faster and more efficient processing of transactions.

Buterin's proposal also emphasizes the need for stable data availability sampling and competitive block production, which are critical for maintaining a healthy and efficient network. By simplifying the consensus layer, the Ethereum network could achieve better performance and reliability, positioning itself to better compete with other blockchains that have gained traction in recent years. The urgency for such innovations is underscored by the migration of users to layer-2 scaling solutions, which has negatively impacted Ethereum's base layer revenue.

However, the response from the Ethereum community has been mixed. While some members view Buterin's proposal as essential for revitalizing Ethereum's competitive edge, others express concerns regarding the feasibility of such a fundamental change. The need for further discussion and clarity on implementation strategies is evident, as the community grapples with the implications of this significant shift.
