Ethereum’s co-founder Vitalik Buterin unveiled a groundbreaking proposal to replace the Ethereum Virtual Machine (EVM) with RISC-V, set to enhance efficiency and scalability.
-
This transformative shift could yield efficiency gains of up to 100 times, while maintaining essential features of Ethereum intact.
-
According to Buterin, developers will continue to utilize existing tools and languages, ensuring seamless backward compatibility for current EVM contracts.
Vitalik Buterin proposes a radical overhaul of Ethereum’s infrastructure with RISC-V, promising efficient smart contracts without compromising core functionalities.
Buterin Proposes Ditching EVM for RISC-V
In a recent post on the Ethereum Magicians forum, Vitalik Buterin outlined an ambitious plan to transition Ethereum’s smart contract execution from the Ethereum Virtual Machine (EVM) to RISC-V, an open-source instruction set architecture. This significant change is primed to tackle some of Ethereum’s most pressing scaling issues by enhancing the efficiency and simplicity of smart contract execution.
Buterin emphasized that the proposed transition aims to resolve lingering scalability challenges, particularly in maintaining competitive block production rates and improving the efficiency of zero-knowledge (ZK) proofs within the EVM context. He noted, “It aims to greatly improve the efficiency of the Ethereum execution layer, resolving one of the primary scaling bottlenecks, and can also greatly improve the execution layer’s simplicity – in fact, it is perhaps the only way to do so.”
Currently, implementations of ZK-EVM consume a considerable portion of their proving cycles executing EVM code. With the proposed native RISC-V virtual machine, Ethereum could unleash potential efficiency enhancements of up to 100x, radically transforming the blockchain’s operational dynamics.
Importantly, the transition would preserve fundamental aspects of Ethereum’s existing architecture, allowing for continuity for developers and users alike. Core elements such as accounts, smart contract storage, ETH balances, and cross-contract calls will remain unchanged. This means developers can continue to write contracts in familiar programming languages like Solidity or Vyper, which would merely need compilation to RISC-V instead of EVM bytecode. Thus, toolchains and workflows will remain largely unaffected, facilitating a smooth transition for all stakeholders.
Another critical aspect of the proposal is backward compatibility. Existing EVM contracts will continue to function seamlessly alongside new contracts written for the RISC-V architecture, ensuring a unified Ethereum ecosystem.
Buterin presented several feasible implementation strategies to integrate RISC-V into the Ethereum framework. The first approach would enable native support for both EVM and RISC-V smart contracts. The second strategy involves wrapping EVM contracts to operate via an interpreter constructed in RISC-V, allowing for a full transition without compromising compatibility. Lastly, a more modular approach would incorporate interpreters into the core Ethereum protocol itself, standardizing support for the EVM and future virtual machines.
Referring to the aspirations of the proposal, Buterin remarked, “The idea is equally as ambitious as the beam chain effort,” indicating that the execution layer’s overhaul is as crucial as innovations being explored for the consensus layer.
For context, the Ethereum Beam Chain project seeks to refine the consensus layer, focusing on enhancing speed and finality, as well as improving mechanisms for scalability and security, with anticipated developments commencing in 2026. This latest proposal echoes Ethereum’s broader strategy towards increased modularity, operational simplicity, and long-term scalability.
Additionally, recent updates highlight Buterin’s ongoing inclination towards privacy-preserving technologies within Ethereum’s ecosystem. Along with this proposal, the upcoming Pectra upgrade, scheduled for May 7, aims to further enhance Ethereum’s functionalities.
Despite these promising developments, Ethereum has been experiencing notable market challenges, consistently trading at its lowest levels since March 2023. With a substantial year-to-date decline of 50.8%, Ethereum’s market dominance recently hit a five-year low. The ongoing volatility impacts its broader adoption and investor sentiment.

However, COINOTAG analytics revealed a modest recovery over the past two weeks, with ETH climbing by 6.1%. In the previous day, it recorded a gain of 1.7%, currently trading at $1,639.
Conclusion
In summary, Vitalik Buterin’s proposal to transition from EVM to RISC-V marks a potential turning point for Ethereum, focusing on scalability and simplicity without detracting from existing functionalities. The ambition behind this initiative reflects a commitment to innovating within the blockchain space, ensuring that Ethereum remains a front-runner in the cryptocurrency landscape. The implementation of these changes, if successful, could fulfill long-term scalability goals while fostering a developer-friendly environment. Stakeholders will be keenly observing developments as Ethereum navigates these transformative changes.
