I'm learning about Lightning and I have some questions:

1. Casa Hodl's Casa Node and installing your own node, e.g. Pierre Rochard's Lightning Power Node Launcher on an old computer, is that the exact same thing?

2. So it's a node that just verifies payments, right?

3. And it pays a (very, very small) fee of a couple of sats, right?

Hi, I'd like to become a "Certified Bitcoin Professional":

But I've been putting it off, so I thought I'd try to find someone to take it with me. The idea is to study for the exam together (the idea is *not* to take the exam together; just study for it). I can put in 1 to 2 hours a day.

Looks like there are 33 topics so it'll take 1 to 2 months to study (just a rough estimate).

Anyone up for this?
