Anchorproof

Verify a signature artifact and optionally countersign to complete the envelope.

Anchorproof produces verifiable evidence and an audit trail, shaped like an advanced electronic signature. It is not a qualified electronic signature and not a QTSP service. The service proves that a specific document hash was signed by the holder of a specific key at a time attested by named timestamp authorities. It does not establish the signer's legal identity. No document bytes, signing keys, or personal information are stored.
