Check License Validity

Enter your license passphrase, then upload your proof.json file or paste it. The zk proof is verified in your browser; your passphrase never leaves the page. Every flow queries a public Mina node for current license state, and completes an ownership sign-challenge round-trip with the zkLicensing verify service (only a signature — not your passphrase — is sent).

Step 1

Required to prove ownership. Stays in your browser — never sent to any server.

License Expired
The proof is cryptographically valid, but the license period has ended. If you renew within 7 days of expiry, the new term extends from the original expiry — otherwise from today.

How verification works

🔐 Runs in your browser. The zk proof is checked locally against a compiled-in verification key. Your passphrase never leaves the page.

⛓ What goes over the wire. A read from a public Mina node (current expiry / revocation) and a signature — derived from your passphrase — sent to the verify service to prove ownership.
