Reply to your comment “Do retail investors also need to understand the builder setup”… I think knowing about 70-80% is enough: when you place an order, it doesn’t go directly into the block; someone (a bundle/ builder) will package it and choose the transaction order, which can affect your slippage, front-running, or even feeling like your order was “stolen” despite being executed. To put it simply, don’t worry about how they auction or run their algorithms internally, just remember two things: 1) Don’t aggressively trade large amounts on illiquid pools on-chain, 2) Use protected routing/limit orders when possible—don’t skip steps just to save time. Recently, L2s are arguing about TPS, fees, and subsidies every day, but I’m more concerned about the details of “how transactions are inserted into blocks.” If the structure is unstable, no matter how pretty the numbers look, it’s just superficial… Let’s leave it at that for now.
