  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x5cb7978a147c7ebfb35e57925738792a0831365122300e32a6d6054e25eba121. Chain 2 (Bitcoin): anchored in block 956304 (2026-07-02T03:55:08Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/0mNDvJY9K4HM3gKUXbetjn.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/0mNDvJY9K4HM3gKUXbetjn.
