  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x3f7c7092c984241bf1ce1da2e5ff43ac068a68336b0113cf43396889a9ef80f1. Chain 2 (Bitcoin): anchored in block 956312 (2026-07-02T05:09:12Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/0bMEyzsRHntTnsBmTUp4N8.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/0bMEyzsRHntTnsBmTUp4N8.
