Welcome.

The blockchain is only one small part of bitcoin. Its important but has become a distraction. Without the distributed network of nodes and miners it is just a slow database. Without proof of work it is just a slow database. Without the 21 million cap enforced by the node operators it isn't that interesting. I hope you learn a lot on this site, I know I have. Keep your mind open and a teachable attitude and you will learn many things.

Stay humble, stack sats.
