  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xb3344975294c404fc4932ab1a8cfb3ee9ecd7d31ecc084dc0199ede373bbb64a. Chain 2 (Bitcoin): anchored in block 956302 (2026-07-02T03:30:09Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/0gOtoAPQJNW80hN8s1xtIk.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/0gOtoAPQJNW80hN8s1xtIk.
