The write-up
Barkmesh: Bitcoin without internet*
Ark-to-Ark bitcoin payments over a LoRa mesh — phone wallet signs locally, gateway relays.
~1.4 KB per payment at ~16 B/s over raw MeshCore datagrams, so settlement takes minutes.
* someone is bound to have a starlink somewhere - slap on a meshcore node and bitcoin kinda works.
