Ethereum L2 project Linea announces a shift to the RISC-V architecture to address the complexity caused by rewriting constraint modules during each hard fork. The RISC-V design makes the proof system more efficient, enabling real-time construction and rapid processing of proof segments. This transition aligns with the Ethereum Foundation's RISC-V roadmap, with more technical details to be released later.

ChainCatcher reports that the Ethereum L2 project Linea posted on X that its cryptography researcher, Alexandre Belling, announced on Ethproofs that Linea will shift to the RISC-V architecture. The main reason is that each Ethereum hard fork requires a complete rewrite of the constraint module, causing the team to contend with long-term adversarial complexity rather than advancing cutting-edge performance. RISC-V offers only 32 registers and approximately 40 instructions. For the proof system, this results in a narrower tracking scope, enabling real-time construction, and the prover can immediately begin processing proof fragments.

Additionally, RISC-V features a narrower execution trace and Type-1 compatibility, while also maintaining zkC (constraint native language), Vortex and Arcane (proof/aggregation stack), and formal verification. Linea stated that this move is highly aligned with the RISC-V roadmap being promoted by the Ethereum Foundation, and more technical details will be released in a few weeks.
