LayerZero Research completes formal verification of Jolt bytecode expansion

  • 60 of 67 RISC-V instructions fully proven in about 2.5 months
  • Verification used Lean against the LeanRV64D reference model derived from Sail
  • Seven instructions remain unproven due to documented edge cases
  • AI tools Claude and Codex were used to accelerate proof generation
Why it matters: Formal verification reduces the risk of errors in zkVM code, which underpins trust in ZK proofs and LayerZero's cross-chain infrastructure.
