Since I started recording the mempool, the biggest change isn't "understanding the terminology better," but rather that I don't get easily scared when observing things. Terms like data availability, ordering, finality sound pretty mysterious, but basically there's one main thread: whether the transaction you see has been seen by others, whether it can be front-run, and whether it will ultimately fail. When DA (Data Availability) issues arise, it's like the sky suddenly fogs up; the on-chain surface looks calm, but you can't see what's happening behind the scenes. If ordering gets chaotic, it's like an intersection without traffic lights—MEV cars jump ahead of you directly. Unstable finality is the most annoying—it's clearly shown as finalized, but then later it seems like it never happened... Now I keep track of these "sensations," so when I encounter gas spikes or strange arbitrage patterns, I can roughly tell which part is causing trouble. Recently, the economic collapse of blockchain games feels quite similar: inflation kicks in, studios are naturally the front-runners, and when token prices slide, everyone's "finality" instantly becomes uncertain. Anyway, when I see this kind of spiral, I tend to hold back a bit.
