  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x650ebb9db4fdf773864807d611c5552fc0a966d517bf810256f6f8f3b4856d8c. Chain 2 (Bitcoin): anchored in block 953513 (2026-06-13T12:47:07Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/28E21YBEiY80Db1o5TAKPG.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/28E21YBEiY80Db1o5TAKPG.
