I just saw an interesting discussion that says MEV is basically like queue-jumping on-chain—someone can see orders in the transaction queue ahead of time, then use their own transaction to squeeze in front and profit from the spread or snatch an arbitrage opportunity. Honestly, I used to think this is pretty far from regular users, but when you think about it carefully, every time you set your slippage too high, you might be leaving a door open for those “queue-jumpers.”

Lately, Layer2s have been competing on TPS, fees, and subsidies—things have been lively—but hardly anyone talks about the fairness of ordering: who decides whether your and my transactions are processed on a first-come, first-served basis, or based on who pays more? In any case, I feel that even if there are more Layer2s, if the underlying logic of ordering isn’t figured out, in the end it may only be changing locations while the “queue-jumping” continues. As a long-term believer, I’d rather be a bit slower, but I hope to see a more transparent set of rules—because the core of a chain is trust, not speed.
