Every stamp's canonical row hash gets submitted to public OpenTimestamps calendars, which aggregate into a Bitcoin OP_RETURN transaction. Once anchored, any Bitcoin node can independently confirm the proof of existence with no trust in ChargeMark. The proof file is included in the downloadable proof package as ots_proof.ots.

Confirm the file you have matches this stamp.
