  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xcf61bca1f1b25a1e3034fe79d38ef5dcf9cd62efe1f6f158b71bff9d2ece7404. Chain 2 (Bitcoin): anchored in block 956375 (2026-07-02T16:51:38Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/2CVEpRwfDCvCdXePI6cIDP.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/2CVEpRwfDCvCdXePI6cIDP.
