Chain 2 (Bitcoin): anchored in block 953528 (2026-06-13T15:41:10Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/2vzoWzmjgs4SyPwv4VBqC6.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/2vzoWzmjgs4SyPwv4VBqC6.
