 Reticulum is a cryptography-based networking stack for wide-area networks built on readily available hardware, and can operate even with very high latency and extremely low bandwidth. Reticulum allows you to build very wide-area networks with off-the-shelf tools, and offers end-to-end encryption, autoconfiguring cryptographically backed multi-hop transport, efficient addressing, unforgeable packet acknowledgements and more.
 
 Reticulum is a complete networking stack, and does not need IP or higher layers, although it is easy to use 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.

 ## Caveat Emptor
-Reticulum is relatively young software, and should be considered as such. While it has been built with cryptography best-practices very foremost in mind, it _has not_ been externally security audited, and there could very well be privacy-breaking bugs. If you want to help out, or help sponsor an audit, please do get in touch.
