A 36-character UUID.

How it worksFull mechanism
  1. Paste the ID

    The ingest response returns it as event_id. It is also on the event in the dashboard and in every proof link.

  2. Read the signed envelope

    The proof page shows the issuer, the hashes and the Ed25519 signature exactly as recorded, read from the ledger when you open it.

  3. Compare your copy

    Paste the SHA-256 payload hash, or the exact payload JSON, and it is checked against the anchored record.

What the proof page showsAPI reference
  • Issuer and whether its domain is verified
  • event_type and the time it was ingested
  • payload_hash and event_hash, both SHA-256
  • The Ed25519 signature and the public key that made it
