When a person arrives in a new country with only a passport and money, they can manage to live there. Dining at a restaurant requires money, not a passport. Staying at a hotel requires both money and a passport. This serves as the starting point for how Keychat thinks about the online world: user-controlled IDs and wallets.

Why doesn't Keychat directly support relay-based unencrypted groups in Chat? Large-scale public groups without end-to-end encryption are a different type of application, similar to Discord or forums with a chat interface. Keychat is designed for small-scale, end-to-end encrypted private groups, where most members are friends rather than strangers. Therefore, Keychat will indirectly support relay-based groups instead of mixing them with encrypted groups, which would cause confusion. View quoted note →
