I’m a big fan of Raspberry Pi, and I’m also a big fan of Bitcoin. What if there were a guide on how to combine these amazing things? It turns out, there are a few such guides, and my favorite one is RaspiBolt. It can guide you through every step of setting up a fully functional Bitcoin node on a Raspberry Pi. It also has a section on enabling instant payments via Lightning Network. I enjoyed reading this guide and all of its extra tips and tricks.
