LayerZero Research said it has completed formal verification of Jolt's "bytecode expansion" — the process Jolt uses to emulate RISC-V instructions it doesn't handle natively by breaking them down into instructions it does. The work covers a core component of Jolt, the zk-VM powering Zero's proving architecture.
The team is releasing all related artifacts, including a preprint of the paper. LayerZero framed formal verification as stronger than conventional testing, which can only sample a subset of inputs, whereas formal verification proves behavior across all cases.
