  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x10a989934e7d81066ca2ddd4f6a69d078f45303cb4e1da8065c465422812c5e1. Chain 2 (Bitcoin): anchored in block 953515 (2026-06-13T12:53:06Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/5ClmwNjQAz1RwLw16V8hsz.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/5ClmwNjQAz1RwLw16V8hsz.
