Ethereum Layer 2 project Linea has announced its transition to the RISC-V architecture, as revealed by cryptography researcher Alexandre Belling on Ethproofs. This shift aims to address the complexity challenges posed by Ethereum hard forks, which necessitate complete rewrites of constraint modules. RISC-V's streamlined architecture, with 32 registers and around 40 instructions, allows for real-time execution trace building, enabling provers to process proof fragments immediately. The transition will maintain compatibility with zkC, Vortex, and Arcane, while also aligning with the Ethereum Foundation's RISC-V roadmap. Linea plans to release further technical details in the coming weeks.
