Lately, I keep seeing people talk about “data availability, ordering, finality.” A bunch of terms sound really impressive, but if you boil it down to one line: for the transfer I sent out, can anyone actually look it up, can it get queued according to the rules, and in the end can it be firmly locked in—no last-minute second thoughts, no regrets.

Data availability is like “whether the surveillance footage exists,” ordering is like “whether your turn will get cut in line,” and finality is whether “the door lock has truly latched.” When I look at on-chain projects myself, I first check whether these three points can line up with each other; if they can’t, even if people hype it up, I don’t really dare to get involved.

Recently, there’s been more news about some places tightening and then loosening taxes/regulations. So everyone’s in-and-out funds sentiment swings back and forth—tight for a while, then relaxed. Actually, the more it’s like this, the more we should keep the “keys” and permissions tightly guarded, and not, in a moment of impulse, open the door to strangers… Forget it—I won’t talk too much for now. Tonight, I’ll re-check my commonly used addresses once more.
