Host an event whose attendee list can never leak. Set a deposit and a capacity; no account needed.
▶ Play: create an eventFor groups that can’t afford a leaked list
Attendees scan one QR code with any Zcash wallet. The deposit is shielded: nobody can see who paid, including the organiser.
The ticket is a random secret made on the attendee's phone. The door checks its hash against a list of hashes, and never learns a name.
Everyone who came is refunded automatically, to an address only they know. No-show deposits go to the group's fund.
If the organiser’s laptop is seized
Every RSVP tool keeps a database of people. Breaches, subpoenas and stolen devices turn it into a target list. Unlisted only stores random ticket hashes and one-time refund addresses, and deletes them after the event.
That works because of Zcash’s shielded pool: a deposit can come from someone unknown, and a refund can go back to them, with nothing on the public chain linking either to a person.
