I started recording some "scary-sounding" words to see what they actually feel like on the chain. Data availability basically means: did the bytes you sent get seen by everyone, and can they still be retrieved later; ordering is about: who comes first or second, deciding whether your transaction is normal or gets front-run; finality is more straightforward: whether this transaction is truly "set in stone" or if someone changes their mind later. The main point is: when block space is limited, these three issues will become very expensive and easily cause people to panic. By the way, I also want to complain that recently people have been using ETF fund flows and US stock risk appetite to explain crypto price movements… which isn’t entirely wrong, but sometimes the congestion and front-running on the chain are the direct reasons why your wallet hurts. Anyway, I’ll keep this in mind; the more I note down, the less likely I am to be scared by technical terms.
