DeepMind AlphaProof Code Completes Signal Machine-Code Verification in Four Weeks, a First for Protocol Formal Proof
Google DeepMind's AlphaProof Code framework generated more than 6 million lines of Lean proofs in four weeks to verify Signal's post-quantum handshake, triple ratchet protocol, and forward secrecy down to the ARM machine-code level. It required human review for 1% of the code and detected two intentionally implanted old bugs.
