JORDY or Joint Optical Reflective Display is an optical viewing device developed based on NASA technology. It is used to help the visually impaired see and read. The name is inspired by the Star Trek
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 0x9c7607016073887ee13d43fca3246d3339ea8268fdaaa00a9d6409b3b0c8cf36. Chain 2 (Bitcoin): anchored in block 953736 (2026-06-15T03:21:19Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.
