Overview

This page describes the architecture for a private, distributed messaging system. Participants have their own private keys (identity) and encrypt messages end-to-end. Each participant may use several nodes, which can be personal devices, self-hosted or vendor servers; this avoids centralization and allows for server failure and going offline.
