  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x501aab1c85a817acd9b89818d9df6c2b8413c5bfb7cca4cbbb9dd2029d38a906. 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/65HpdutR964Uue9p8L094c.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/65HpdutR964Uue9p8L094c.
