Today I was staring at the mempool again for a while, like watching a congested highway: you think you've "sent it out," but you're just waiting in line at the entrance, and miners/validators pick the more attractive ones to go first. The most torturous part during a jam is psychological expectation—sometimes you wait half a day with no movement, then suddenly it gets packed; or maybe you speed up by changing the gas, but the previous transaction gets stuck, and a whole string of subsequent ones have to wait... I, who love to break nested structures, find it pretty exciting, wildly waving my hands.

A colleague passing by glanced at my screen and said, "Aren't you just paying to cut in line?" It sounds simple but is quite accurate.

Recently, there's been a lot of comparisons between RWA, US bond yields, and on-chain yield products. I'm even more concerned about the "realization path": no matter how good the returns look, when the chain gets congested and fees spike during operation, the friction during entry and exit in those few minutes is very real. Anyway, I now think carefully before placing an order: if I have to wait 20 minutes, can I still accept it?
