  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 0x5ef15e3d1b9d45ca200cffd12b163715453e7cf84eac412f247db6ea444d8cf3. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID. Verify: download https://artists.proofprofile.net/proofs/artist/cf3827fd-0c68-4ecb-b452-ade43c8681ec.json and https://artists.proofprofile.net/proofs/artist/cf3827fd-0c68-4ecb-b452-ade43c8681ec.ots, the client at https://opentimestamps.org runs `ots verify -f record.json proof.ots`.
