  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x60cf0be4d777af04e4aa82f5e1e4eb58e4094bd095cccb4142d905c1632d7da2. Chain 2 (Bitcoin): anchored in block 957124 (2026-07-08T03:53:27Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/5l4uJihTAZpgS6a0ii6mDa.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/5l4uJihTAZpgS6a0ii6mDa.
