Description (from the catalogue, unverified)
Timestamp and notarize any file, data or AI agent log by its SHA-256 hash: blockchain proof of existence and integrity for tamper-evident audit trails, anchored on Polygon in minutes, then Bitcoin (OpenTimestamps); not a notary act. Returns proof_id, certificate, proof.json and evidence ZIP, verifiable without Sellat. Use when you must prove exact data or an agent record existed and is intact.
