Lately I keep seeing words like "data availability, ordering, finality," which sound academic, but I can focus on just one main line: the on-chain results you see are whether "everyone can verify and they won't be changed."

Data availability = whether the data is exposed for people to check;
Ordering = how transactions are queued, who jumps the line;
Finality = whether this transaction is truly settled and unchangeable.
To put it simply, if DA is missing, you can only trust others' stories; if ordering is messed up, you have to accept the reality of being front-run or sniped; if finality is slow, don't jump to conclusions too early.
Recently, on-chain data tools/tags have been criticized for lagging behind or even misleading, which makes me anxious too...
So now I prefer to look more at the "trend" of transaction volume and capital flow when analyzing the market, rather than blindly trusting individual tags.
Anyway, I still believe: things that can be independently verified by more people will eventually win.
That's all for now.
