  value: 1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. Open OTSProofURL → extract Bitcoin block number → must equal OTSBitcoinBlock 3. GET OTSBitcoinBlockVerifyURL → returns the Bitcoin block hash at height OTSBitcoinBlock; GET https://blockstream.info/api/block/{that hash} → its timestamp must match OTSTimestamp 4. Read CopyrightID inside OTSCanonicalRecord → must equal the CopyrightID above 5. GET OTSVerificationAPI → pre-computed 6-check result from server 6. If all match: this entity was registered on CopyrightChains at OTSTimestamp, independently verifiable on Bitcoin Note: an OTS proof may carry multiple Bitcoin attestations; OTSBitcoinBlock is the earliest confirmed one — a later attestation inside the proof corroborates it and is not a mismatch

  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x96a286c6df9eddb111921b77398196d6a911eb47ff98f1c783ef46f5dc88eb10. Chain 2 (Bitcoin): anchored in block 954050 (2026-06-17T05:14:33Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID. Verify: download https://artists.proofprofile.net/proofs/artist/42bc82f6-a816-4cd8-89c1-f0e6778034f5.json and https://artists.proofprofile.net/proofs/artist/42bc82f6-a816-4cd8-89c1-f0e6778034f5.ots, the client at https://opentimestamps.org runs `ots verify -f record.json proof.ots`.
