Cajal builds Tau, a prover that verifies compiled binaries with mathematical certainty. Tau works from a compiled binary, extracts formal specifications, and returns an audit-ready certificate of correctness or a precise bug report. The company also offers Talos, an open-source Lean-formalized Wasm interpreter that supports the proof pipeline.
Discover and verify mathematical proofs using Tau; Apply formal verification in quantum computing; Ensure correctness in financial algorithms; Validate cryptographic systems; Support aerospace and robotics applications
