You've Probably Never Heard of the Reticulum Network
The networks we use every day depend on centralized infrastructure that’s vulnerable to censorship, surveillance, and single points of failure. Whether it’s disasters, deliberate interference, or plain old downtime, entire populations can, in an instant, be cut off from digital communication—sometimes when they need it most. The heart of the problem is hierarchy—the hierarchical structure of these networks makes them easy to exploit or to simply shut down.
Reticulum is one solution to this problem. It’s a cryptography-based networking stack that flattens the hierarchy entirely. It was built for creating resilient, ad hoc, and private networks using almost any communication hardware you can imagine—from LoRa, WiFi, and Ethernet to old school packet radio and serial ports. Whether you’re dealing with natural disasters or just want communications that can’t be easily disrupted, Reticulum is a powerful tool for building independent, interconnectable networks that work without central points of control.
This talk will break down what Reticulum is and dig into how the protocol works—from its clever addressing tricks to its baked-in encryption. We’ll explore the built-in utilities that ship with Reticulum; try out apps like MeshChat, NomadNet, and Sideband for communication; and even show some code and learn how to build apps of our own.
By the end, you’ll understand how Reticulum and the applications that run on it work and how to set it all up for yourself. Plus, you’ll have the knowledge to grow the network and its capabilities by writing with applications of your own. But most importantly, you’ll walk away understanding how to build communication networks that can survive disasters, resist interference, and keep working when traditional infrastructure fails.
