  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x72710701f055f93f4545cfb4e0067bac2efdc11304a9159b935e498d539b83de. Chain 2 (Bitcoin): anchored in block 953513 (2026-06-13T12:47:07Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/5yx8EZA8L9CCWGYj4haNvU.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/5yx8EZA8L9CCWGYj4haNvU.
