Ethereum is brewing a profound technological transformation led by ZK technology.
Ethereum is attempting to build not just a more efficient execution layer, but a modular architecture compatible with multiple virtual machines.
Navigating Web3 tides with focused insightsBy Haotian
A friend asked me what I think about @VitalikButerin's radical proposal to replace Ethereum Virtual Machine (EVM) bytecode with the open-source RISC-V instruction set architecture. At its core, Ethereum is preparing for a profound technological transformation led by zero-knowledge (ZK) technology. Let me break down the strategic logic behind this:
1) In fact, Vitalik’s idea of replacing EVM with RISC-V isn’t entirely new. As early as when he introduced the Rollup-Centric scaling roadmap, he had already hinted at a similar vision: allowing qualified Layer 2s to become execution layers of the mainnet, while demoting EVM from the protocol layer to an “in-house” Rollup execution client—effectively turning it into just one among many alternative virtual machines (AltVMs).
The key enabler of this shift lies in RISC-V serving as a lower-level, more universal instruction set architecture that can provide a unified "hardware" foundation for zkVMs, enabling various execution environments to operate efficiently under a single framework. However, this architectural overhaul depends on Ethereum completing its foundational deployment of SNARKs, because only when ZK technology can be applied at scale to state validation can such a modular execution-layer design achieve efficiency gains without compromising security.
2) Frankly speaking, Ethereum’s strategic pivot may appear at first glance like a bold act of self-reinvention—but upon deeper analysis, making the execution layer interchangeable is actually an inevitable evolution for established, consensus-strong blockchains like Ethereum. Faced with technical disruption from high-performance newcomers like Solana and Sui, along with market fragmentation caused by numerous EVM-compatible chains, Ethereum has chosen proactive innovation over passive defense.
In pure technical metrics, Ethereum’s TPS indeed struggles to compete against these newer blockchains. Yet throughout the scalability trilemma, Ethereum has consistently upheld security and decentralization as its two core values, all while maintaining unmatched ecosystem vibrancy and developer momentum.
If adopting an open-source ISA like RISC-V could significantly boost execution-layer efficiency—with potential 50x to 100x performance improvements in ZK proof generation—then upgrading the execution layer without sacrificing these foundational strengths becomes a no-brainer. This strategy preserves Ethereum’s core advantages while directly addressing its primary weaknesses.
3) That said, amid the excitement over this new proposal, we must recognize that transitioning from EVM to RISC-V won’t happen overnight. From a technical roadmap perspective, this transformation likely cannot advance fully until ZK-SNARKs are deployed at scale.
Compared to previous major upgrades in Ethereum’s history—such as the consensus-layer transition from PoW to PoS—the entire process will require careful design, extensive testing, and strong community backing. Optimistically, it could take at least 2–3 years.
Nonetheless, Vitalik emphasized backward compatibility in his proposal. Existing EVM contracts might continue running via a RISC-V interpreter or through parallel support mechanisms—an approach critical to minimizing transition costs for developers and users alike. This incremental transformation reflects the prudent,稳健 (steady) upgrade philosophy that any secure, decentralized legacy blockchain must adopt.
In my view, Vitalik’s proposal to replace EVM with RISC-V is far more than a mere technical re-architecture—it represents Ethereum’s proactive response to competition from high-performance blockchains. Closely tied to upgrades outlined in Ethereum’s roadmap such as Verge and Purge, this initiative fundamentally revolves around full-scale SNARKification, aiming to build a more efficient and flexible execution environment capable of supporting diverse future applications.
Earlier, @drakefjustin revealed that the Ethereum Foundation plans to invest tens of millions of dollars into zkVM projects. Undoubtedly, zkVMs are becoming one of Ethereum’s central narratives. What Ethereum seeks to build is not merely a faster execution layer, but a modular architecture capable of supporting multiple virtual machines. This discussion around replacing EVM with RISC-V may just be the beginning.
