Recently, a bunch of people are arguing about data availability, ordering, and finality—just the terms make you want to think about web pages… actually, just follow one line: can your transaction actually be “seen by everyone, inserted in what order, and finally be considered valid”? Data availability = not just stored on a single node’s computer, everyone needs to be able to access it; ordering = who goes first, who goes later, determines whether your transaction is confirmed or gets front-run; finality = don’t have it overturned and reorganized a few minutes later.

Retail investors complain that ordering is unfair and MEV is ugly, I’m not surprised at all. When miners/validators face increased income pressure, they love to tinker with the order even more. Anyway, I have two personal habits: if I can avoid unlimited approvals, I won’t use them (seeing them just makes me angry), and don’t blindly trust “submitted = guaranteed,” until finality is reached, treat it as still in transit. That’s all for now.
