LayerZero Research formally verifies Jolt bytecode expansion
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.

- We’ve completed formal verification of Jolt’s “bytecode expansion” - the process Jolt uses to emulate the RISC-V instructions it doesn’t handle natively, by breaking them down into ones it does. We’re releasing all the artifacts related to this effort: a preprint of the paper Replying to their earlier post: Most software is tested by running it against a bunch of inputs and seeing how it behaves. This is, by its nature, incomplete: you can only ever test a sample. Formal verification is different. In la…x.com ↗
