| These meshnets use inexpensive LoRa radios to run long-range off-grid communication platforms. Basically you set up these small radio devices, some of which look like a microchip with an antenna attached, others of which look like small walkie talkies, and use them to send texts (usually by connecting them to a cell phone with an app or similar). There's a ton of interesting things you can do with the network as long as you can do it by sending short text messages. People run Internet of Things -style devices using these networks, they set up Tile-style trackers with small GPS-enabled chips that shout out their location on the meshnet, there's all kinds of clever stuff. But it's not equivalent to the internet - you can't set up and visit web sites or anything like that. | These meshnets use inexpensive LoRa radios to run long-range off-grid communication platforms.

| So this one is more complicated - it's basically a lot of the above but also it's a whole alternate internet. Reticulum is a whole cryptography-based network stack which [[https://slrpnk.net/post/12490840|feels like it was developed from the ground up out of radio networking protocols]]. It can run over the same LoRa radio devices Meshtastic and Meshcore can use, but it can also use ad-hoc WiFi, data radios, modems, serial lines, amateur radio digital modes, and it can even tunnel through the Internet (meaning you could set up a local mesh of LoRa radios, old personal computers and laptops, and whatever wireless routers and other networking gear you can find, connect a neighborhood together using Reticulum as the underlying network, then connect that through the internet to Reticulum networks anywhere in the world. You can write software to run on Reticulum, and it already has a bunch of programs like [[https://github.com/markqvist/nomadnet|NomadNet]] which can do encrypted messaging (same goal as Meshtastic and Meshcore) but also host and view text-based web pages and I think some other stuff. In a lot of ways, this one feels like the meshnet you'd see in a scifi book, an all-encrypted network stack that allows you to just link together any old hardware you can scrape together and rebuild a decentralized version of the internet grounded in much more secure protocols. (I'll admit I straight up don't understand how a lot of this works on the network/cryptography level, it actually seems similar to [[https://www.torproject.org/|Tor]] in some ways but I don't understand that very well either.) | So this one is more complicated - it's basically a lot of the above but also it's a whole alternate internet.
