The word noema (plural: noemata) derives from the Greek word νόημα meaning "mental object".Nicholas Bunnin and Jiyuan Yu (ed.s) The Blackwell Dictionary of Western Philosophy, Wiley-Blackwell, 2004, p
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
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x25ad137eb065e7a72f22a6a1c48737641ea73d88eb407b7bfe5919c6f9d263ba. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z).
