  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x45f23e7b5a8a0d4be0d9bab932bb482ce75fdb4dbf9e4dc966c08e2300912689. Chain 2 (Bitcoin): anchored in block 956304 (2026-07-02T03:55:08Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/7wOCOv9FrVuOLfcVPnMeGJ.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/7wOCOv9FrVuOLfcVPnMeGJ.
