I'm a little new at all this stuff. But when you say full node, is that the Bitcoin core I run on my Umbrel server? I guess it is full because it has the entire blockchain on it but it doesn't earn any sats for having it. I guess I never got that. SOMEONE somewhere gets paid pretty well to "verify" transactions, and yet, as far as I understand it, the Bitcoin core I have and many others have verified transactions for consensus. Do you have to have a miner setup to get a piece of all those transaction fees?

Just curious. I'm happy to support the network and love learning about the technology.
