irdest is a decentralised networking project, aiming to create easy-to-use solutions for ad-hoc wireless communication. It supports many common desktop operating systems (Linux, Windows, MacOS, BSD, …), and Android mobile phones. iOS support is on the roadmap.

irdest is both a cross-platform application, implementing messaging, filesharing, and voice calls, but also a development toolkit to create fully decentralised third-party applications.

In order to be able to run on unpriviledged mobile platforms irdest implements decentralised routing protocols and utilities entirely in userspace. The codebase is largely written in Rust, with only a few compatibility components being written in more platform specific languages. All parts of the project are contained in this repository.

Following is an overview of the available components. Components have additional information in their respective README files.

Component	Description
clients	irdest end-user applications for various platforms
docs	Manuals (for both users and developers), and tools to build and deploy documentation
irdest-core	Core library of the irdest ecosystem. Provides networking abstractions, user management and discovery
licenses	Set of license texts that are in use in this repository
netmods	Platform-specific networking interface drivers
nix	Nix related build utilities
ratman	A decentralised and modular userspace frame router
rpc-core	Core components of the qrpc development system
sdk	Software Development Kit libraries for third-party developers
services	A collection of services that use irdest as their network backend. Some are part of the irdest clients, others are development examples
utils	Various utilities in use all over the repository that don't fit in anywhere else

Overview

Most traditional networking infrastructure (both the transmission layer, as well as applications) operate in a centralised way. Clients connect to servers, and devices to towers. This makes the infrastructure vulnerable to attacks. Natural disasters or opressive governments can easily shut down communication for millions of people, potentially putting them at risk, and slowing down or disrupting any organisation or activist movement.

Irdest aims to solve this issue by creating decentralised circuits between devices directly. These direct device-to-device connections can be imperfect and unstable. irdest's routing approach takes these issues into account by caching undelivered messages, and carrying them towards their destination until the receipient comes back online.

Routing in a irdest network is done via a user's ed25519 public keys, creating a 32 byte large address space. Connecting devices together happens via channel-specific drivers (for example the tcp internet overlay). Therefore when creating a circuit, roaming between different connection types is normal, and no single technology has to work on all possible devices.

How to use

There's no single way to use irdest. Various platforms support different clients, and an irdest network can consist of many different components interacting with each other. To get started, check out the user manual!
