To put it simply, retail investors really don’t need to study “block builders” like a thesis.
You just need to know: some transactions are bundled together and not necessarily executed in the order you see;
Dirty tricks like front-running and sandwich attacks are often hidden inside bundles, so don’t chase orders recklessly during network congestion, and don’t use obvious market orders to go all-in.
As for how builders compete and how MEV revenue is split, just get a rough idea—enough to help you avoid pitfalls.
Anyway, I now only use L2 solutions when I can; if the mainnet gets too expensive, I back off.
