Ethereum Layer 2 project Linea has announced a shift to the RISC-V architecture, according to Foresight News. Alexandre Belling, a cryptography researcher at Linea, revealed the decision at Ethproofs, citing the need to rewrite constraint modules with each Ethereum hard fork as a major factor. This shift aims to reduce complexity and enhance performance.
RISC-V architecture offers 32 registers and approximately 40 instructions, providing a narrower tracking range for proof systems. This allows for real-time construction and immediate processing of proof fragments. Additionally, RISC-V features a narrower execution path and Type-1 compatibility, while maintaining zkC (constraint native language), Vortex, Arcane (proof/aggregation stack), and formal verification.
Linea noted that this move aligns closely with the Ethereum Foundation's ongoing RISC-V roadmap, with further technical details expected to be released in the coming weeks.
