Recently, I saw a bunch of people discussing modularization and DA layers, which makes developers' eyes light up, while ordinary users are completely confused, and I'm pretty much the same. Actually, don’t be scared by the terminology; I focus on one main line: when I transfer money out, when is it considered to have "really arrived," and whether anyone can cut in line to change the order in the middle. DA, simply put, is about not losing data, so others can verify this transaction; ordering is about who goes first and who goes later, not getting sandwiched; finality means not telling me two hours later that it was rolled back. For someone like me who’s security-obsessed, it’s okay to confirm a bit later, but what I fear most is seeing the funds arrive but not being stable. Anyway, I’d rather spend less effort; having the assets alive is the most important.
