Recently, many people are discussing modularization and the DA layer, developers' eyes light up, while ordinary users look confused and say "What are you talking about"… Don’t be fooled by the terminology, basically there’s one main thread: Has the “data” of your transaction been seen by everyone, who’s ordering it, and does it truly settle in the end.

Data availability means: don’t just give you a result hash and expect to fool people; the data must be accessible for others to verify and recompute. Otherwise, if something goes wrong, you won’t even have proof to criticize. Sorting is more practical: who can jump the queue, who can rollback, MEV is not mysticism, it’s about permissions. Finality is simpler: don’t tell me “it will theoretically finalize,” what you should ask is: how long before it can be reversed? Who takes the blame if it’s reversed? Anyway, I look at projects based on this criterion; any other narrative is just a cover-up.
