Portable evidence

The merchant keeps this, not a screenshot.

A screenshot proves nothing and a log can be edited. This record is cryptographically signed, so the decision can be re-verified, unaltered, long after the transaction.

POST-QUANTUM READY

Every record is signed twice.

A classical ES256 signature and a post-quantum ML-DSA-65 signature, the NIST-standard lattice scheme, cover every FLINT record. The proof you keep today stays verifiable even after quantum computers can break classical signatures.

The ES256 compact JWS remains inside the portable hybrid envelope. The post-quantum ML-DSA-65 signature travels beside it, over the same canonical payload.

Signed receipt

A human-readable summary of the verification record the merchant keeps as proof.
