Linea will shift to the RISC-V architecture, aligning closely with the RISC-V roadmap promoted by the Ethereum Foundation.

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 message: An Ethereum L2 project Linea posted on X that its cryptography researcher Alexandre Belling announced on Ethproofs that Linea will move to a RISC-V architecture. The main reason is that with every Ethereum hard fork, the constraints module needs to be completely rewritten, causing the team to deal with complexity for the long term rather than pushing cutting-edge performance. RISC-V only provides 32 registers and about 40 instructions. For the proving system, the tracking scope is narrower, it can be built in real time, and the prover can immediately start processing proof fragments.

In addition, RISC-V has a narrower execution trace and Type-1 compatibility, while still retaining zkC (constraint native language), Vortex and Arcane (the proving / aggregation stack). Linea says this move is highly consistent with the RISC-V roadmap the Ethereum Foundation is pushing forward, and more technical details will be released in a few weeks.
