In a world where digital communication is often subject to surveillance, censorship, and centralized control, Reticulum stands as a revolutionary solution. Designed as a cryptography-based networking stack, Reticulum empowers individuals and communities to build local and wide-area networks using readily available hardware. Unlike traditional networking technologies, Reticulum operates efficiently even under extreme conditions, such as high latency and ultra-low bandwidth.
Reticulum is more than just a network—it is a tool for creating thousands of independent and autonomous networks that interconnect seamlessly. These networks are designed to function without kill-switches, external control, or centralized oversight, allowing users to communicate freely and securely. Reticulum enables sovereign, censorship-resistant, and decentralized communication, making it a game-changer for those seeking privacy, security, and resilience in their networks.
Unlike conventional network stacks, Reticulum does not rely on the IP protocol or higher layers. However, it can still be encapsulated over IP networks, allowing users to tunnel Reticulum traffic through the Internet or private IP infrastructures when necessary. By eliminating dependencies on traditional networking protocols, Reticulum optimizes performance and security. The stack is built directly on cryptographic principles, ensuring stable and resilient functionality even in trustless and adversarial environments.
One of the most remarkable aspects of Reticulum is its ease of deployment. It requires no kernel modules or special drivers, making it incredibly lightweight and accessible. Running entirely in user space, Reticulum can be installed on virtually any system that supports Python 3, from personal computers and embedded devices to large-scale infrastructure. This versatility ensures that users can establish secure and sovereign communication networks without specialized or expensive hardware.
Reticulum: A New Era of Secure Networking
Reticulum is the cryptography-based networking stack for building local and wide-area networks with readily available hardware. It can operate even with very high latency and extremely low bandwidth. Reticulum allows you to build wide-area networks with off-the-shelf tools, and offers end-to-end encryption and connectivity, initiator anonymity, autoconfiguring cryptographically backed multi-hop transport, efficient addressing, unforgeable delivery acknowledgements and more.
The vision of Reticulum is to allow anyone to be their own network operator, and to make it cheap and easy to cover vast areas with a myriad of independent, inter-connectable and autonomous networks. Reticulum is not one network. It is a tool for building thousands of networks. Networks without kill-switches, surveillance, censorship and control. Networks that can freely interoperate, associate and disassociate with each other, and require no central oversight. Networks for human beings. Networks for the people.
Reticulum is a complete networking stack, and does not rely on IP or higher layers, but it is possible to use IP as the underlying carrier for Reticulum. It is therefore trivial to tunnel Reticulum over the Internet or private IP networks.
Having no dependencies on traditional networking stacks frees up overhead that has been used to implement a networking stack built directly on cryptographic principles, allowing resilience and stable functionality, even in open and trustless networks.
No kernel modules or drivers are required. Reticulum runs completely in userland, and can run on practically any system that runs Python 3.
Reticulum: The Unstoppable, Sovereign Networking Stack
A Vision for Sovereign Communication
Reticulum is more than just a network—it’s a framework for building thousands of independent networks. Unlike traditional systems, Reticulum eliminates the need for central control, allowing anyone to operate their own sovereign communication infrastructure. The key vision behind Reticulum is to empower individuals and communities to create networks that are free from surveillance, censorship, and external control.
With Reticulum, users can establish highly secure communication channels, ensuring that their data remains private and tamper-proof. This is particularly crucial in regions where communication restrictions are imposed, or in emergency scenarios where traditional networks fail.
What Makes Reticulum Different?
While Reticulum serves the same fundamental purpose as other networking stacks—moving data reliably from one point to another—it does so in a completely different way. Here are some notable characteristics that set Reticulum apart:
Privacy & Security by Default
- Reticulum does not use source addresses in transmitted packets, making it impossible to trace the origin of communication.
- All encryption keys are ephemeral and provide forward secrecy, ensuring that past communications remain secure even if future keys are compromised.
- It is impossible to send or receive unencrypted packets within Reticulum, eliminating vulnerabilities associated with unprotected data transmission.
Decentralization & Sovereignty
- There is no central authority controlling address allocations; users can create addresses as needed.
- Once an address is generated, it remains globally reachable and portable, meaning it can be moved across different locations in the network while staying accessible.
- Networks built on Reticulum are self-configuring and resilient, adapting to various communication mediums seamlessly.
Interconnectivity & Versatility
- Reticulum supports a wide range of communication hardware, including LoRa radios, AX.25 packet radio TNCs, WiFi, Ethernet, serial devices, and even free-space optical links.
- It allows seamless integration over existing IP networks (TCP/UDP), meaning it can function over wired and wireless infrastructure while maintaining security and decentralization.
- By combining multiple communication mediums, Reticulum enables the creation of dynamic, self-healing mesh networks that are highly resistant to disruptions.
Supported Hardware & Interfaces
Reticulum is designed to work over virtually any medium that can sustain a half-duplex connection with at least 500 bits per second throughput. Some of the supported hardware and interfaces include:
- Ethernet and WiFi devices
- LoRa radios using RNode
- Packet radio TNCs (AX.25 and KISS-compatible)
- Any serial-based communication device
- TCP and UDP over IP networks
- Custom hardware via standard input/output (stdio) and pipes
For example, a simple Raspberry Pi setup connected to a LoRa radio, a packet radio TNC, and a WiFi network would allow devices on each of these mediums to communicate seamlessly, thanks to Reticulum’s self-configuring architecture.
How to Get Started with Reticulum
Getting started with Reticulum depends on your intended use case. However, installation is straightforward using Python’s package manager:
pip install rns
Once installed, you can start Reticulum manually or set it up as a system service using the rnsd utility. The first time Reticulum runs, it automatically generates a configuration file that helps you connect with local peers and expand the network from there.
For more details, consult the Getting Started Fast section of the Reticulum Manual.
Included Utilities for Network Management
Reticulum comes with several built-in utilities to simplify network setup and maintenance:
- rnsd – Runs Reticulum as a background service.
- rnstatus – Displays real-time information about network interfaces.
- rnpath – Manages and views routing paths.
- rnprobe – Diagnoses connectivity to specific destinations.
- rncp – Transfers files securely between nodes.
- rnx – Executes remote commands over Reticulum networks.
These tools ensure that even networks operating over extremely low-bandwidth mediums, such as LoRa or packet radio, function efficiently and reliably.
Applications Built on Reticulum
Reticulum powers several innovative applications that demonstrate its capabilities:
- Nomad Network – An off-grid, encrypted, and resilient mesh communication platform.
- Sideband – A user-friendly graphical messaging app for Linux, Android, and macOS.
- LXMF – A distributed, delay-tolerant messaging protocol designed for asynchronous communication.
These projects showcase Reticulum’s ability to facilitate secure and decentralized digital interactions without reliance on traditional internet infrastructure.
Performance & Future Development
Reticulum is optimized for a broad range of performance scenarios, with speeds ranging from 150 bits per second to 40 megabits per second across different mediums. While development continues, the focus remains on expanding functionality for low-bandwidth networks, ensuring long-term resilience and adaptability.
