Lately I keep hearing people talk about "data availability, ordering, finality," a bunch of terms that give me a headache. Actually, I’ve come up with a main thread for myself: whether the order you place and the on-chain result you see can actually be "confirmed" by everyone as the same thing. Data availability is like whether the ledger content is public and can be verified; ordering is about who comes first and who comes later, avoiding being cut in line; finality means this matter shouldn’t be overturned again after a few minutes. To put it simply, if these three are unstable, candlestick charts are like reflections on a wet road—shimmering, making you think there's a breakout, but in reality, it’s just car headlights. By the way, I checked the funding rate again, and it’s extremely extreme. The group is arguing fiercely: is it a reversal or just a bubble squeeze… I’m actually more concerned now about whether congestion/reordering will force me to be the last one holding the bag. Better to tighten up leverage first and get a good night’s sleep. (I don’t know if I’m just being too timid.)
