  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xf2ad8fc611c9aa5d3d60e54af3ec05b8c3f1797556a02f5f1c8930a099f401dc. 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/7CcUBFsHkzjN6lO1AHY2I4.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/7CcUBFsHkzjN6lO1AHY2I4.
