Show HN: Talos – Open-source WASM interpreter for Lean
Talos is an open-source WebAssembly interpreter developed in the Lean 4 programming language, designed to prioritize formal verification and correctness over execution speed. It utilizes weakest precondition calculus to allow developers to reason about program behavior and prove correctness within the same codebase.
Why it matters
It represents a significant advancement in formal methods for software security, enabling developers to mathematically verify the behavior of WebAssembly code.
Talos is a WebAssembly interpreter written in Lean 4, named after the bronze giant of Greek mythology who guarded Crete — a mechanical guardian, built to enforce rules.
