DeepMind's AlphaProof Code Agents Produce Lean Proofs That Signal's Compiled Encryption Code Meets Its Specification
Agent teams produced millions of lines of machine-checked proof in about four weeks against roughly 26,000 lines of human-written specification, and the checks correctly failed on two reintroduced bugs.
Google DeepMind introduced AlphaProof Code on November 10. It is a multi-agent framework that writes proofs in the Lean theorem prover to verify security properties of software. The first target was Signal's core encryption. Unlike most ear…

Part of a tracked trend
AI-Written Formal Proofs Become a Software Assurance Tool
Agent-generated, machine-checked proofs are lowering the cost of formally verifying production code, so more security-critical software will ship with proof artifacts and human effort will shift to writing and auditing specifications.
