Lately I keep hearing people talk about data availability, ordering, finality—so many terms that just give me a headache… I’ll just focus on one main thread: whether your transaction can “be seen and verified by others,” and whether it can be “reordered to cheat,” and finally, “when is it considered truly finalized and not rolled back.” To put it simply, data availability is like whether your receipt is there after you place an order, ordering is like who the cashier serves first, and finality is whether you can change your mind after the transaction is complete.

By the way, I have some doubts about the current social mining and fan token models that say “attention is mining”… Attention is definitely valuable, but on-chain it ultimately comes down to: don’t lose data, don’t reorder transactions maliciously, and don’t confirm falsely. Otherwise, all the hype ends up being paid for by users. Anyway, in my practical tests, I focus on these three things: even with minimal slippage, I’m afraid of being front-run, and that’s a disaster.
