An infix is an affix inserted inside a word stem (an existing word or the core of a family of words). It contrasts with adfix, a rare term for an affix attached to the outside of a stem, such as a pre
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 0xab0886f603d6a6a101a99b1abf25e96cc071ff8aa296ef01eea584d23ac966d5. Chain 2 (Bitcoin): anchored in block 953746 (2026-06-15T05:25:34Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.
