VEXIDUS · POST-QUANTUM INTEGRITY FOR AVIATION RECORDS · blockchain.aero

A part outlives the cryptography that signs it.

An airworthiness record has to stay verifiable across the thirty-year life of an airframe. The signatures protecting those records today will not survive the quantum transition. Vexidus is the integrity layer built so a record signed now is still provable decades from now.

falsified

The record is only as honest as its paperwork.

Counterfeit and falsified parts records are a safety problem wearing a paperwork disguise. A records-falsification scandal forced the industry to treat traceability as urgent, not optional. Coalitions are now publishing recommendations for uniform digital traceability, and legislation moving through 2025 pushes the entire supply chain toward digitized, permanent records. The direction is set. Aviation's records are going digital, and they are going permanent.

Permanent records. Temporary signatures.

The incumbents already moved, and they moved to permissioned ledgers signed with classical cryptography. Hundreds of thousands of widebody parts are tracked on back-to-birth platforms. Optical fingerprinting is paired with blockchain for provenance. Major IT providers and OEMs all run programs. Every one of them signs records with cryptography a quantum computer is expected to break inside the same thirty-year window those records must survive. The data will still be there. The proof of who signed it, and that it was never altered, will not.

Signatures that do not expire.

Vexidus signs every record with a Dilithium3 and Ed25519 hybrid. One signature carries classical security for today and lattice-based, quantum-resistant security for the decades after the transition. A record signed on Vexidus is verifiable now and stays verifiable once classical signatures fail. We are not asking aviation to rip out the ledgers it is building. We are the integrity layer those ledgers anchor to, so the proof beneath them never has an expiry date.

ED25519 classical security
DILITHIUM3 post-quantum security
HYBRID SIGNATURE one durable proof
classical security  +  post-quantum security  =  one durable proof

We design for horizons most software never reaches.

Durability across decades is not a feature we bolted on. It is how the work is built. Settlement at a Distance, our architecture for monetary and logistics systems beyond Earth, plans in horizons of thirty to a hundred years. The discipline that asks how a ledger survives the distance to another planet is the same discipline that asks how an airworthiness record survives the life of an airframe. The aviation problem and the off-world problem are the same problem at different scales: keep a record true across time no one party controls.
