I'm just someone who loves analyzing on-chain data. Recently, everyone has been talking about "data availability, ordering, finality," and it's giving me a headache. Actually, focusing on one main thread is enough: whether your transaction can ultimately be "seen and recognized" by everyone. Data availability is like whether the receipt is publicly displayed; ordering is about who goes first and who goes after, and whether someone can jump the queue; finality is whether this matter is considered settled and official. When the group chats about stablecoin regulation, reserve audits, and various "de-anchoring" screenshots, emotions tend to take over, and people forget this main thread... I now prefer to focus on whether the data can verify itself, how long confirmation takes, and what happens during congestion or rollbacks. It's okay to take it slow—first confirm what can be confirmed.
