PANews reported on March 30th that Linea, an Ethereum Layer 2 project, announced its switch to the RISC-V architecture. For the previous three years, Linea had been using a direct arithmetic implementation of the EVM. While this approach had been launched on the mainnet and become an industry benchmark, each Ethereum hard fork required rewriting the constraint module, forcing the development team to expend considerable effort on complexity. The switch to RISC-V reduces the instruction set from the complexity of the EVM to approximately 40 instructions, resulting in faster prover startup and Type-1 compatibility from day one.

Linea stated that the Ethereum Foundation is working on RISC-V, which clarifies the direction of Ethereum's proof layer development. Linea will retain its constraint language zkC, proof aggregation stacks Vortex and Arcane, and formal verification capabilities, while gaining advantages such as a truly modular, community-auditable stack and zero critical third-party dependencies.
