Verifiable licences and permits
Hypothetical. Not a client, not a result.
// The problem
Printed licences and certificates are easy to copy, and anyone who needs to check one has to phone or email the issuing office.
// What we would build
Licences and permits issued as verifiable credentials the holder keeps on their phone, signed by the government, with a permissioned ledger operated by participating public bodies that lists issuers and revocations so anyone can check one in seconds. If only one office issues and checks, a signed database record is simpler.
// What is in it
- Credentials issued to the holder's digital wallet when a licence is granted
- Revocation and expiry visible to every verifier immediately
- A permissioned ledger of issuers and revocations, with no personal data on it
- A verification page and app for businesses and other agencies
- Open standards, so the credential works with other wallets and governments
