I got confused for the third time by words like "data availability / ordering / finality"… Later I came up with a main thread for myself: when you click confirm on the chain, who is actually queuing first, is there a place to check the data, and will it eventually be reversed or reorganized. Basically, there are three things: can you see it, who makes the decision, and can you back out.

Recently, new L1/L2s have started offering incentives to attract TVL, and old users complain about "mining, selling, and dumping" — I understand… If the chain becomes more complex, and the queuing layer isn't stable, the experience of rushing or cutting in line becomes very discouraging; if finality is slower, the mindset shifts to "let's not get excited yet, wait until it’s truly implemented." For someone like me who is impulsive, I can only hold back a little; if I really want to buy, I set a stop-loss first, just like that.
