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 0x8c1fb476c68cb82aca04e851eaf60f955f53fd0e79c6e7b01efc15bfbbef038c. Chain 2 (Bitcoin): anchored in block 954019 (2026-06-16T23:44:13Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.
