Just as I was sipping coffee and scrolling, I came across another wave of L2 mouthwatering battles: your TPS is lower, my fees are cheaper, and my subsidies are bigger... It made me feel like I was at a market shouting to see who has a louder voice. To be honest, don’t be scared by the terminology, just focus on one main thread: first, “who takes the transaction first and writes it down” (data availability), then “who decides the order” (sequencing), and finally “how long it takes to truly be irreversible” (finality). These three are like express delivery: first, you need a tracking number to check, then don’t get jumped in line, and finally, don’t say the next day that you didn’t receive it. Subsidies are obviously attractive, but I care more about whether you can account for the situation when things go wrong, and whether you can clarify the issues... Anyway, I’m increasingly treating choosing a blockchain like choosing a food delivery platform.
