  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x89a469690afd9e7d3cb60e590d97a1e30658ba7392e3874dc0e6953c3d1a4df8. Chain 2 (Bitcoin): anchored in block 954130 (2026-06-17T19:50:41Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/42TGS6JN4IbUj0hjo0i67q.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/42TGS6JN4IbUj0hjo0i67q.
