Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xd6aa16a98e6789a8cc6066a5e24dd617a25cd4d71ae44985cd4f963c83880331. 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/649MjecPXaKLCtZeJpFyJT.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/649MjecPXaKLCtZeJpFyJT.
