Recently, I saw a bunch of people being scared by words like "data availability / ordering / finality." Actually, just focus on one main line: do you believe that this transaction "really happened, the order wasn't manipulated, and you won't regret it in the end"? Data availability is about "whether the records can be retrieved if something goes wrong"; ordering, simply put, is who goes first, who goes later, and whether someone was inserted into the queue; finality is when you think you've secured your funds, but a few days later, the other party changes their statement... that kind of cold feeling.

These days, hardware wallets are out of stock again, phishing links are everywhere, and the more anxious you are, the easier it is to click the wrong thing. Anyway, I’m not chasing new terms anymore; I want to understand these three things first: "Where am I signing," "Who am I giving my money to," and "Can I verify it."

Next time, I plan to: never click on unfamiliar links, and before making a transaction, check the order and confirmation status more carefully. How do you judge whether "you can sleep peacefully on this chain"?
