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 0x73e87aa9ffa639f5ec77cb6987e6b6f731e2bf0d5101e0a5505276286aa3bd8d. Chain 2 (Bitcoin): anchored in block 953641 (2026-06-14T13:54:28Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.
