Lately I keep hearing people mention "data availability, ordering, finality," sounding like three mystical courses... actually, just follow one line: you think the transaction has already happened, but can others actually "see and verify," and when is it truly considered settled? If the data isn't public or accessible, even the strongest consensus is like a black box; who decides the ordering determines whether you're cut in line or sandwiched; if finality is a bit slow, you have to wait a few more minutes before celebrating, or else a rollback might hit, and you'll be wearing a liquidation raincoat straight away.

On the macro side, they're talking about rate cut expectations, the dollar index, risk assets rising and falling together—basically, when sentiment heats up, on-chain congestion gets worse, and ordering gets messier. Don't just blame the "market." I'll go revoke the authorization of a few old contracts first, so I don't wake up one day and find myself "educated" on finality.
