Recently, I've been looking into blockchain builders / bundles and other related things. The more I look, the more I feel that retail investors don't actually need to understand the level of "I can also write a builder." To put it simply, you only need to know: the transaction you send out may not go directly into a block; it might be bundled together with others and inserted. Someone might choose the order, insert transactions to jump the queue, or even add some other operations before or after yours to eat your slippage... The "why I get front-run whenever I buy" you see often is just this chain of events acting up.

So my own passing line is: don't blindly believe that "on-chain transparency = fairness." For important operations, try to use routes with anti-front-running features / private sending methods (use them if available; if not, avoid playing with thin liquidity). Don't set slippage too high, and when prices are surging, it's better to miss out than to chase aggressively. As for bundle details, who collaborates with whom, how MEV revenue is split—I mostly see them as gossip. If you really want to dig deep, it's not something a quick snack can handle.

By the way, recently there's been a lot of fuss about the "yield stacking" in staking / shared security setups. My colleague just said: where does this yield come from, and who is backing it? After hearing that, I can only nod... Anyway, the more complex the path, the more you have to assume someone is adjusting the order or siphoning off funds where you can't see. That's all for now.
