What is Reticulum?

Reticulum is a cryptography-based networking stack for building both local and wide-area networks with readily available hardware, that can continue to operate under adverse conditions, such as extremely low bandwidth and very high latency.

Reticulum allows you to build wide-area networks with off-the-shelf tools, and offers end-to-end encryption, forward secrecy, autoconfiguring cryptographically backed multi-hop transport, efficient addressing, unforgeable packet acknowledgements and more.

From a users perspective, Reticulum allows the creation of applications that respect and empower the autonomy and sovereignty of communities and individuals. Reticulum enables secure digital communication that cannot be subjected to outside control, manipulation or censorship.

Reticulum enables the construction of both small and potentially planetary-scale networks, without any need for hierarchical or beaureucratic structures to control or manage them, while ensuring individuals and communities full sovereignty over their own network segments.

Reticulum is a complete networking stack, and does not need IP or higher layers, although it is easy to utilise IP (with TCP or UDP) as the underlying carrier for Reticulum. It is therefore trivial to tunnel Reticulum over the Internet or private IP networks. Reticulum is built directly on cryptographic principles, allowing resilience and stable functionality in open and trustless networks.

No kernel modules or drivers are required. Reticulum can run completely in userland, and will run on practically any system that runs Python 3. Reticulum runs well even on small single-board computers like the Pi Zero.
