Reticulum Mesh Networking is Solarpunk
We spend a lot of time here talking about the aesthetics and social aspects of Solarpunk which I love, but I would like to submit some infrastructure for your consideration.
Reticulum is a networking protocol that was designed for complete autonomy. It doesn't rely on an ISP, satellites, cell towers, or anyone besides you and your neighbors with some $30 hardware. It can form mesh networks with WiFi routers, LoRa radios, ethernet connections, bluetooth, even serial cables and packet radios. And it can seamlessly connect all of those disparate devices into one network.
It rethinks what we really need to have a functioning community network - no it's not capable of gigabit speeds, in fact much of what it does is measured in bytes. But this is the part that feels really "solar" to me - doing more with less.
The autonomy, DIY adaptability, and built in cryptography with privacy at its core are decidedly "punk".
If this intriguing to you the manifesto, Zen of Reticulum (linked), written by the creator of Reticulum is a fun read.
r/reticulum has all kinds of cool projects added on a routine basis, and happens to be one of those corners of reddit that stills feels like "old reddit".
