I’ve been lurking in the group for a long time, and today I still couldn’t help popping in to say something... Lately everyone’s been talking about modularization, and also the DA layer—developers are endlessly reposting with tons of passion. On the user side (like me), though, I’m just totally clueless: these terms all sound like fresh “fertilizer” for new growth.

But really, you can just grab one main thread: in the end, can your chain “settle the account”? Ordering is simply—don’t mix up the sequence. Finality means that after some time, you won’t be able to go back and regret it. Data availability is more straightforward: the ledger contents must be something you can get and verify—otherwise, to put it plainly, you’re just trusting thin air.

Anyway, when I look at a project, I don’t chase concepts. First I see how it ensures “no changing the accounts, no losing the accounts,” and then I decide whether to add a little bit of “water” into it—step by step.
