These days I see a bunch of people discussing data availability, ordering, finality—so many nouns that it can easily scare people off… I personally focus on one main thread: who do you really trust, and at what moment does it count as “this transaction has truly been finalized”? Whether the data can be retrieved and re-verified by everyone (not just screenshots later), who is in line (queue-jumping is way too common on the chain), and whether waiting a few seconds or minutes makes you feel secure—these three things are actually connected.

By the way, I thought of the economic collapse of blockchain games, with inflation + studios + coin price spirals—basically, it’s also because “finality” comes too quickly: once it crashes, it crashes completely, leaving no window for retreat. I no longer believe in the idea that “if the mechanism is well-designed, it can be self-consistent”—anyway, first look at whether the transactions and capital flows are aligned; if they’re not, treat it as a cloudy day and hold back.
