Verify a Timestamp

A timestamp proves a record existed at a point in time. CertNode timestamps are countersigned by an independent RFC 3161 Time Stamp Authority (FreeTSA) and, where requested, anchored to the Bitcoin blockchain via OpenTimestamps.

How to verify

  1. 1Find your timestamp ID (looks like ts_…).
  2. 2Paste it into the proof portal and verify. No account required.
  3. 3The result shows the cryptographic checks the record actually carries — signature, hash, and any RFC 3161 / Bitcoin timestamps.
