Big Eyes is a 2014 American biographical drama film directed by Tim Burton, written by Scott Alexander and Larry Karaszewski, and starring Amy Adams and Christoph Waltz. It is about the relationship b
1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. Open OTSProofURL → extract Bitcoin block number → must equal OTSBitcoinBlock 3. GET OTSBitcoinBlockVerifyURL → returns the Bitcoin block hash at height OTSBitcoinBlock; GET https://blockstream.info/api/block/{that hash} → its timestamp must match OTSTimestamp 4. Read CopyrightID inside OTSCanonicalRecord → must equal the CopyrightID above 5. GET OTSVerificationAPI → pre-computed 6-check result from server 6. If all match: this entity was registered on CopyrightChains at OTSTimestamp, independently verifiable on Bitcoin Note: an OTS proof may carry multiple Bitcoin attestations; OTSBitcoinBlock is the earliest confirmed one — a later attestation inside the proof corroborates it and is not a mismatch
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x2ce74f27c625fcdd0755592f2ef6a73ee676ad4c207f7c92075f766c24e7d9db. Chain 2 (Bitcoin): anchored in block 953599 (2026-06-14T06:43:55Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.
