Recently, I saw a bunch of people scare newcomers with "data availability/ordering/finality," but honestly, it's just about one thing: who gets to queue your transaction first, whether others can verify the data, and whether it might suddenly fail. Don't get confused by the terminology; the core is "can everyone see it + can the order be changed + can it be counted." I treat complexity as the enemy, and if it can be explained in one sentence, I won't bother with a three-paragraph summary. By the way, the NFT royalty debate also looks a lot like this: creators want stable income, the market wants better sales, but in the end, it all comes down to "who sets the rules and whether they are reliably enforced." Anyway, I look at projects first to see if the team clearly explains these points; if they can't, they probably aren't willing to be responsible to users.
