Recently, everyone has been talking about data availability, ordering, finality—so many terms that sound like exam questions… I’ll just focus on one main line: Can others actually “see” this transaction (whether the data is publicly recorded), can it be front-run (who controls the ordering), and when is it truly finalized (finality—don’t think that just because the interface shows success, everything is settled). Basically, it’s all about asking: Will this transaction be manipulated or rolled back? By the way, I want to complain that hardware wallets are still out of stock, phishing links are rampant—especially during times like this, don’t rush to click on “airdrops/subsidies” links. I’d rather take a few extra steps to split addresses and devices than cry later. That’s all for now.
