The Utopia universe
Welcome to Utopia.
A small, entirely invented state where the paperwork actually works. The Registry keeps the records, the DMV and the Bank issue digital credentials to your wallet, and the Marketplace and UPay ask for exactly as much as they need — and not a field more.
Utopia is a demonstration environment for the Multipaz digital-credential stack. Nothing here is real: no real people, no real money, no real groceries. Credentials issued here are test artifacts and are accepted nowhere outside this playground.
Offices of the state
Two issuers, one system of record, and two places to spend what you hold.
R
Registry
The system of record. Every fictional resident and the
data the state holds on them — the source every credential is built from.
System of record

stopped printing plastic; you decide which parts anyone gets to see.

for a digital ID and learn that you are over 18 — never your date of birth.

Send money between accounts. Your wallet signs the payment
authorization and that is the whole ceremony.
