CAIN-42 Verification Center

Every public CAIN-42 claim is in one registry, signed with the CAIN-42 evidence-root key. Press Verify CAIN-42. Your browser checks the signature, then fetches and SHA-256-hashes every artifact behind every claim. Nothing is taken on the server's word. Claims that are NOT_IMPLEMENTED, and results that came out negative, are listed too.
