DeepMind AI Proves Signal's Crypto
Researchers at Google DeepMind used the agentic AI framework AlphaProof Code to formally verify the cryptographic guarantees of the Signal protocol in a four-week proof of concept.

🔥 What happened
Google DeepMind used agentic AI to formally verify key cryptographic guarantees of the Signal protocol in just four weeks. Its new AlphaProof Code framework found no new flaws but correctly flagged known vulnerabilities in older Signal versions.
💡 Why it matters
Formal verification—the holy grail of software security—used to take months of manual proof-writing. DeepMind shows agents can slash that effort, delivering the first AI-assisted validation of a protocol protecting billions of messages.
⚡ Our take
Impressive, but DeepMind verified only a slice of Signal and won't disclose costs. Until someone names a price, this is a PR win—not a product.
