  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xcbcd5e7ab58f870deb5a112d245b62544242f0cf46c64e0a04476c46f93f7b93. Chain 2 (Bitcoin): anchored in block 956304 (2026-07-02T03:55:08Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/6OfRlxCZEErtqQcBq6dudX.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/6OfRlxCZEErtqQcBq6dudX.
