Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/34PWkiTDmG9lAJ3leUGOri.json contains the same CopyrightID — hash it and compare to OTSHash, then confirm the Bitcoin block independently via OTSBitcoinBlockVerifyURL or https://artists.proofprofile.net/api/v1/bot/ots/verify/track/34PWkiTDmG9lAJ3leUGOri.
