Yeah, that’s not easy to understand at first.
Two books I would recommend on the subject:
Inventing Bitcoin by nostr:npub1fqn4fgzkk8nm2x3wd600n935c9tc7xgg9jhk5dfa0kuvrgvsyv7sgu536l
The Blocksize War by Jonathan Bier
nostr:npub1h8nk2346qezka5cpm8jjh3yl5j88pf4ly2ptu7s6uu55wcfqy0wq36rpev recorded both of them on audiobook, they’re outstanding.
