Reticulum is a cryptography-based networking stack designed for building local and wide-area networks using readily available hardware. It operates effectively in adverse conditions with high latency and extremely low bandwidth. The vision focuses on enabling individuals to operate sovereign communication networks, making it affordable to cover vast areas with independent, interconnectable networks. Reticulum offers unstoppable networks free from surveillance, censorship, and control.

Unlike traditional networking technologies, Reticulum eliminates source addresses, preventing packet origin tracking. It operates without central address space control, allowing anyone to allocate addresses as needed. Newly generated addresses become globally reachable within seconds to minutes, offering self-sovereign and portable communication endpoints.

All communication employs strong modern encryption by default, with ephemeral keys ensuring forward secrecy. Unencrypted links are impossible in Reticulum networks—destinations drop unencrypted packets as invalid. This approach enables construction of both small and planetary-scale networks without hierarchical control structures, preserving individual and community sovereignty over network segments.
