Recently, L2 has started competing again—TPS, transaction fees, subsidies—bickering like street vendors fighting for a spot at the night market… I hear it all as one main thread: in the end, who really has the final say on this chain. Data availability, put plainly, means the ledger must be visible and obtainable—something people can actually retrieve and get their hands on; otherwise, even if you brag that it’s fast, it’s like keeping records in a dark room. Ordering is basically about who gets in line and who cuts—those little MEV tricks are all wrapped up here. As for finality, it’s even more direct: I might buy at the floor and snag a bargain, but don’t come back two days later telling me that this transaction “actually doesn’t count.” Don’t get intimidated by a pile of terms—just focus on these three things: can it be verified, who’s in line, and whether it can go wrong. If you keep your emotions from taking the wheel, you won’t get led astray. Anyway, I don’t dare to go all-in.
