  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xc8bc038e6166e48a5ddce53f1fdf839b3a1c9b5ccc16552cf5838d4704ccc6e8. Chain 2 (Bitcoin): anchored in block 953536 (2026-06-13T17:25:41Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/6dfqb40c8VzgytRbSjZhjs.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/6dfqb40c8VzgytRbSjZhjs.
