Recently, I saw everyone being scared by the words "data availability / ordering / finality," but actually focusing on one main thread is enough: who is in line first when you place an order (ordering), whether others can reconstruct the content after lining up (data availability), and finally whether this transaction is truly finalized and won't be rolled back (finality). After seeing many small incidents on the chain, you'll find that problems are often not "the chain is broken," but one of these three aspects is compromised, and user experience directly becomes mysterious.

By the way, when looking at extreme cases like funding rates, whether the group argues about reversal or continues to inflate the bubble, I actually care more: during these emotionally charged phases, whether exchange/on-chain congestion, delays, or changes in matching order will mislead you... (Don’t ask me how I know). Anyway, I now prefer to make fewer moves and wait until the sense of confirmation returns.
