1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. Open OTSProofURL → extract Bitcoin block number → must equal OTSBitcoinBlock 3. GET OTSBitcoinBlockVerifyURL → block must exist at that height 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
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x378faba638ab0da61ae17c5bf0411df25a977b1a1429cd631fbb71a220166df1. 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/204dbd27-05d3-40a8-8a28-e6c4edfd92a0.json and https://artists.proofprofile.net/proofs/artist/204dbd27-05d3-40a8-8a28-e6c4edfd92a0.ots, run `ots verify -f record.json proof.ots` (https://opentimestamps.org).
