  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xb7887452b1e05808ef2bea1e0f2d8fa4cc10fb727b2043fc8a563ed910f449f3. 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/0koGAxnL8nNWLF6yOHn4NE.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/0koGAxnL8nNWLF6yOHn4NE.
