Someone asked me what the fuss is all about regarding data availability, ordering, and finality. Hearing all these terms just gives me a headache. Actually, I only need to focus on one main point: do you dare to believe in "what has happened on the chain," and whether you can still retrieve and verify it later. Data availability is like whether the ledger is public and can be checked; ordering is about which transaction comes first and which comes later, don’t get front-run; finality is whether this page can be turned over without being torn back and rewritten. When blockchain games' economies collapse, honestly, it’s often because the data is unclear, rules keep changing, and expectations collapse—causing inflation, studios, and token prices to spiral downward together... I no longer chase mysticism when looking at projects; I first check if the data can be obtained, whether there’s room for rule changes, and if it’s stable enough, everything else is up to fate.
