Sign AI decisions with Ed25519, verify them offline.

versyn

Cryptographic proof for AI actions. Sign any AI decision with Ed25519, verify it offline against a pinned public key.

Install

pip install versyn

Use

import versyn
key  = versyn.register("[e-mail]")
cert = versyn.certify(
    {"kind": "agent.decision",
     "payload": {"agent": "underwriter", "action": "decline"}},
    api_key=key,
)
print(versyn.verify(cert))   # True - checked locally, no network call

versyn.verify() runs on your machine. It checks the Ed25519 signature against a pinned public key - it does not call Versyn. If our servers vanished, your certificates stay verifiable.

What this is

A Versyn certificate proves a record was signed at a specific time and has not been altered since. It does not prove the decision was correct, and is not by itself regulatory compliance. It is the verifiable evidence layer beneath your governance.
