Lately I've been looking into MEV (Maximal Extractable Value, basically someone can "cut in line" on the chain to snatch your profit), and the more I read, the more I feel it's not about "high-level players' game," but about ordinary people getting slippage widened, or placing a swap and being front-run before they can react, ending up with a worse execution price and thinking they just shook. Not to mention liquidation and stop-loss orders, which are already tense, but when the order gets reordered, the mental state just collapses.

People always say "on-chain transparency equals fairness," but transparency only means you can see how you're being arranged... Especially when an oracle reports an outrageous price, the community starts collectively "waiting for confirmation," and at this point, who packs the transaction first and who packs it later is no small detail. Cross-chain bridges are the same—after a theft happens, you find a bunch of permissions/whitelists/pausable endpoints. Front-running is just the surface; underneath, it's about who sets the rules and who can intervene. Anyway, whenever I see strange admin powers in a contract, my first thought isn't "for operational convenience," but "if this thing is combined with reordering, it could screw over a lot of people"... That's all for now, continuing to dig.
