Signed by the authority
Every card is an Ed25519 signature over its own data. Change one letter and it fails.
Sona Identity & Immigration Authority
Every persona carries one card nobody can fake.
Arriving in Sona means getting your card. Open an AI influencer and it gets a license of its own. Both are signed, numbered and written to a public record.

Why a copy is worthless
Checked in your browser
The verify page recomputes the signature on your device with our published key, so you don't have to trust our server.
Unique pattern
The guilloche and sigil are drawn from the signature. A number on the wrong pattern gives itself away.
Public, chained record
Every event hashes the one before it. Anyone can download the ledger and replay it.
Eight photos, bound to the card
Face and full body from every side, checked for size, backdrop and reuse, then hashed into the signature. Swap the photo and the card fails.
Two documents, one person
A Resident Card names the persona. Each Creator License names one AI influencer and points back to its holder.
Status that travels
A suspended or revoked card shows it the moment it is scanned, with the reason on record.
