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 news, the Ethereum L2 project Linea tweeted that its cryptographic researcher Alexandre Belling announced on Ethproofs that Linea will transition to the RISC-V architecture. The main reason is that each Ethereum hard fork requires a complete rewrite of the constraint module, leading the team to contend with complexity for a long time instead of pushing frontier performance. RISC-V offers only 32 registers and about 40 instructions. For the proof system, the tracking range is narrower, allowing for real-time construction, and the prover can immediately start processing proof fragments.

In addition, RISC-V has a narrower execution trace and Type-1 compatibility, while retaining zkC (constraint native language), Vortex and Arcane (proof/aggregation stack) as well as formal verification. Linea stated that this move is highly consistent with the RISC-V roadmap being promoted by the Ethereum Foundation, and more technical details will be announced in a few weeks.
