FratRat documentation

FratRat is a privacy-first dating app for college students, built as a native iOS app on zkRP's encrypted peer-to-peer network. See the README for the overview, why zkRP was chosen, and the per-university network model.

How the client uses zkRP

FratRat embeds the zkRP client (libghost) and talks to the network from the device:

• Mesh (Mesh/) discovers zkRP relays over gRPC, connects, and tracks state.
• Profiles carry a name, college, year, bio, and photos; photos are stored as client-encrypted blobs in zkRP's blob store (the app holds the keys).
• Matches and chats ride zkRP mailboxes for store-and-forward delivery.
• Parties use shared (party) mailboxes so an event update reaches every attendee at once.

Privacy properties

Building on zkRP means no central broker sees the graph: enrollment is anonymous (nullifiers, no stored identity), messages and photos are encrypted client-side, and bounded claims like age or distance can be proven without revealing the values. The per-university network model keeps each campus isolated on its own mesh.
