risc-v

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.

ChainCatcher news, reported by The Block, Ethereum co-founder Vitalik Buterin proposed on April 20 at the Ethereum Magicians forum to replace the Ethereum Virtual Machine (EVM) with the open-source instruction set architecture RISC-V to enhance execution layer efficiency.Vitalik pointed out that this move could increase zero-knowledge proof efficiency by up to 100 times while maintaining bidirectional compatibility with existing EVM contracts. The proposal aims to address Ethereum's long-term scalability bottlenecks in data availability, block production competitiveness, and ZK-EVM proofs.

ChainCatcher news, Ethereum co-founder Vitalik Buterin stated that the Reduced Instruction Set Computing (RISC-V) is an important component of the Ethereum Virtual Machine (EVM). Vitalik pointed out that the open-source instruction set is crucial in the existing formal verification roadmap for validity proofs.
