  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xa500e8af9ba2500e0b98675bf0d894c762f86f59eea91af46648eb2299e9e459. 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/6F6sIDHJO7MSrfdCOsXyFi.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/6F6sIDHJO7MSrfdCOsXyFi.
