additional property: OTSVerifyInstructions

  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

  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x6deabcd23073ac93d602c7dbd1f65a7b635c6e90fa1bf5aca62bcb144ed51aec. Chain 2 (Bitcoin): anchored in block 954553 (2026-06-20T11:51:30Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.
