  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x32c4d42b480ae05ffc12c870a5d33f0079931bf9ab63d1bc8ca71cc16e6148e3. Chain 2 (Bitcoin): anchored in block 953528 (2026-06-13T15:41:10Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/5zwyCVmihRh2sme6VocmnW.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/5zwyCVmihRh2sme6VocmnW.
