  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xd78bc33ffd63d7257b5af5733874926fea414da3c551142f7ce26853a45b06ca. Chain 2 (Bitcoin): anchored in block 956349 (2026-07-02T11:34:59Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/2pJUXpzVHESIzA3ig3HuZy.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/2pJUXpzVHESIzA3ig3HuZy.
