At one point I was broadcasting the bitcoin header chain over Lora…you could get it anywhere in Manhattan, basically…. Sadly that range is just short enough to not be super useful.

LoRa meshes might fix this.
At very high density and with repeaters, but iiuc mesh is more about individual message routing, not broadcasting something that’s a constant stream. Sadly bandwidth just isn’t all that available for something like the header chain.
