Proof Launches x401 Protocol for Secure AI Identity Authorization

Proof has introduced the x401 protocol to secure AI identity authorization and digital transactions. This new protocol verifies the people behind AI-generated actions, rather than focusing on verifying the AI itself.

The company has secured over $640 billion in transactions for 10,000 organizations, including 16 Fortune 100 companies.

The x401 protocol uses HTTP 401-style challenges and cryptographically signed verifiable credentials to support selective disclosure and zero-knowledge proofs.
