Just now, I was looking at the order book depth and saw some large orders being placed and canceled repeatedly. I couldn’t help but laugh at myself: I’m really a cancel order hero. Actually, that set of “data availability, ordering, finality” on the blockchain sounds intimidating, but honestly, it all boils down to one main thread—whether the transactions you see are seen by everyone, whether they are inserted into blocks in a certain order, and whether the final result is verifiable and unchangeable.

Recently, someone also complained that validators/miners are making too much profit from MEV, with unfair ordering, and retail investors feeling like they’re waiting in line only to be cut in line… I don’t really understand how to achieve “absolute fairness,” but at least don’t tie “what can be seen” and “who can decide the order” too tightly. Anyway, my own approach is: don’t force it, reduce trades when volatility is high, wait until it’s confirmed and settled, and live to see the next wave.
