AlphaProof Code

AlphaProof Code is a human-AI collaborative framework designed for the formal specification and verification of real-world software. It utilizes autonomous prover agents to generate Lean proofs that link high-level security protocols to low-level machine code, as demonstrated by its verification of the Signal protocol's libsignal implementation.
