Lately I keep hearing words like "data availability, ordering, finality," and it sounds like an exam... I personally see a main thread: whether the transaction you submit really counts as "everyone can see it, the order is recognized, and it won't be reversed at the end." Data availability is like making sure the ledger content isn't hidden; ordering is about making sure no one cuts in line; finality is about not saying two hours later that the previous segment doesn't count. Basically, it's the same mindset as refreshing/retrying transactions, watching the queue and waiting for confirmation. Recently, when comparing RWA, U.S. Treasury yields, and on-chain yield products, I only glance at the yield numbers and get excited easily, but if the underlying main thread isn't stable, even attractive returns aren't reassuring... Anyway, I still prefer cold wallets, slowly reviewing and analyzing.
