This project is a daughter of Scuttlebutt – it takes a similar approach to signed, append-only logs, but radically modifies the format to fit packets of 120 Bytes (including a cryptographic signature). This makes messaging small enough to fit over LoRa, and Bluetooth Low-Energy.
The basic idea is you use your phone (or any device really) to publish messages (text/ audio), and then those messages are replicated over long distances using relays (for example using LoRa - a low power, radio protocol). Because all are messages are cryptographically signed, we don’t need to worry about trusting intermediaries (relays, other peers). Other ways messages can be relayed is directly from device-to-devices using Bluetooth Low Energy (requires zero pairing, peers just need to be within a few meters, and be interested in what each other are “saying”)
