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 artist was registered on CopyrightChains at OTSTimestamp, independently verifiable on Bitcoin
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xaf20a816d6f8645e6c6f7bf4eacc4311e111f56d984e50060d96caf6fec87f6a. Chain 2 (Bitcoin): anchored in block 953627 (2026-06-14T11:43:04Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.
