In this workshop, we implement a local Lightning Network (LN) cluster of several nodes which may continue to operate and process transactions offline for a period if internet connectivity is lost.
This implementation was done using several Raspberry Pi 4 model B units, system details as follows:
- System - Raspberry Pi OS
- Architecture: 64-bit OS
- Kernel Version: 5.15.61
- Debian Version: 11 (bullseye)
Two types of underlying IP networks were used during testing (click for individual details):
- IP-over-Bluetooth Low Energy (BLE) network (Star topology, inflexible)
- Ad-hoc Wi-Fi mesh network (Mesh topology, flexible)
LN channels are then established on top of this IP connectivity.
