  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xdd88946688a43aa58ea17b6c5bf86f77af0e6eb2c731f20b3a0f2d607f0a4f3c. 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/0SxITA6rczbFEtSW04IEl8.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/0SxITA6rczbFEtSW04IEl8.
