Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/1eR2Sjtz31UavzpPO8N52n.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/1eR2Sjtz31UavzpPO8N52n.
