Jafa is a slang term (sometimes pejorative) for a resident of Auckland, New Zealand. It is an acronym, standing for Just Another Fucking Aucklander. This prejudice against Aucklanders started to appea
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 0x703fe667c4adf14e8cd3ca1c727af75b00fb92e4d8131fb1c260aba6680dbd73. Chain 2 (Bitcoin): anchored in block 953795 (2026-06-15T13:44:27Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.
