Linea will shift to the RISC-V architecture, a move that is highly consistent with the RISC-V roadmap promoted by the Ethereum Foundation

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, causing the team to struggle with complexity for a long time instead of pushing for cutting-edge performance. RISC-V only provides 32 registers and about 40 instructions. For the proof system, the tracking range is narrower, can be constructed 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 retaining zkC (constraint native language), Vortex and Arcane (proof/aggregation stack), and 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.
