Recently, people keep throwing around the words data availability, ordering, and finality together, sounding like mysticism... I'll just stick to one main thread: when can users "be confident that this transaction is settled," and whether others can secretly alter what you see. Data availability, simply put, is "can you access the complete ledger details for verification," ordering is "who came first and who came later, was it manipulated into a queue," and finality is "how long before it can't be overturned or reopened."

My mom asked me a couple of days ago while watching me browse on-chain applications: "When you make a transfer, is it considered settled immediately?" I said not necessarily, it depends on how long it dares to boast and whether it can still be rolled back... Anyway, I don't pay much attention to terminology when evaluating projects now; I first look at how they prove the data is actually there, how they explain the ordering rules, and where their finality promises end.

By the way, talking about social mining, fan tokens, and the "attention as mining" approach, I increasingly feel that the core isn't about whether mining is done or not, but about who owns this "data" of attention, whether it can be verified, whether it can be manipulated by reordering, and ultimately, what justifies counting your contribution. Ultimately, it all comes back to that main thread.
