Loading timestamp manifest…
The final hashes of the SSL certificate chain+requests+responses, as well as the TLSNotary zk proof (if enabled) are submitted to the Bitcoin blockchain for timestamping via OpenTimestamps.
- Archive Merkle root
- Stamped manifest SHA-256
Verify publication
Download the proof and manifest, then open OpenTimestamps Stamp & Verify. Select hashes.json.ots and then hashes.json to check the timestamp and its Bitcoin attestation. A pending proof is not yet a confirmed Bitcoin timestamp.
Upgrade and verify later
Keep both files together. After Bitcoin confirmation, upgrade and verify with the OpenTimestamps client:
ots upgrade hashes.json.ots ots verify hashes.json.ots
