  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x1a54e78f04e24570943eb652bfd76f57586fc6537a87daa4f47461e1abc55617. Chain 2 (Bitcoin): anchored in block 953520 (2026-06-13T13:32:09Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/2J9YAQ0SQlE8mn2R00Lp1o.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/2J9YAQ0SQlE8mn2R00Lp1o.
