Recently, I’ve seen a bunch of people talk about data availability, ordering, and finality—scary-sounding nouns, but you only need to grab one main thread: who do you actually trust when it comes to the “sequence/ordering” and the “final state that won’t be changed.” In places like cross-chain bridges, the worst part isn’t that the fees are high—it’s that you think you’ve passed the point of finality, when you actually haven’t, or if the ordering gets messed up, you could end up sandwiched like a sandwich cookie… In any case, what I’m watching is: whether the data is made public enough for others to reproduce and verify, and whether finality really holds—i.e., it isn’t just something claimed in words.
