Lately, when discussing new public blockchains, there's a lot of talk about "data availability, ordering, finality," and the terminology is starting to sound more and more like an exam... I just focus on one main thread: what are users really waiting for? Honestly, when you click confirm, first someone has to put the transaction into a queue (ordering), then ensure others can still verify what exactly was written later (data availability), and finally, whether you're willing to trust the result and not flip out two minutes later (finality). These three things aren't mysterious; they're just "queue - proof of record - stamping."

Recently, a certain region has been discussing tax increases and tightening/relaxing compliance, and everyone's deposit and withdrawal psychology has become noticeably more sensitive. Even if the chain is faster, if finality isn't stable enough, people are hesitant to move large amounts, preferring to wait until clearer rules are established.

My mom asked me a couple of days ago, "On your chain, once you transfer, can it never be changed?" I could only reply half-heartedly: mostly yes, but it depends on how the final confirmation is done... Anyway, I now prefer to look at actual activity and retention. I pay attention to the lively ones, and I can wait for the quiet ones.
