  value: 1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. GET OTSBitcoinBlockVerifyURL → block OTSBitcoinBlock must exist at that height 3. Read CopyrightID inside OTSCanonicalRecord → must equal the CopyrightID above 4. GET OTSVerificationAPI → pre-computed 6-check result from server 5. If all match: this entity was registered on CopyrightChains at OTSTimestamp, independently verifiable on Bitcoin

  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xdc8135bd6b656b5a06c2f74272e6248dcc75ceccf0b2b64ce9271884954fcb67. Chain 2 (Bitcoin): anchored in block 953520 (2026-06-13T13:32:09Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/6tWW1nbvxO3M7j3TclPXBI.json contains the same CopyrightID — hash it and compare to OTSHash, then confirm the Bitcoin block independently via OTSBitcoinBlockVerifyURL or https://artists.proofprofile.net/api/v1/bot/ots/verify/track/6tWW1nbvxO3M7j3TclPXBI.
