Chain 2 (Bitcoin): anchored in block 956312 (2026-07-02T05:09:12Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/0lRuSxi1pi6ONhtGYT1MKS.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/0lRuSxi1pi6ONhtGYT1MKS.
