  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x05a28f248aa4716376d778486e9a00df7f503808409c0353a30878ed68dbf46e. Chain 2 (Bitcoin): anchored in block 957120 (2026-07-08T03:22:41Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/4eRapzclogWNWVmd79GqmI.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/4eRapzclogWNWVmd79GqmI.
