  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xbe2f66803e1f2bb624d6e847faa781285d92afdf070bbff5baf4bf2833adf807. Chain 2 (Bitcoin): anchored in block 956302 (2026-07-02T03:30:09Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/4sjbBrMJxGV64KXSDLmeXL.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/4sjbBrMJxGV64KXSDLmeXL.
