I just finished checking on-chain data and then looked at the hot and cold wallets of a few exchanges. Out of curiosity, I opened a bunch of discussions about "data availability/ordering/finality," the terminology sounds intimidating, but basically it's just one line: Did your transaction get seen by everyone, in what order was it included in a block, and is it ultimately considered final? Recently, it's normal for retail investors to complain about MEV and unfair ordering. When the order gets mixed up, others can front-run the spread, and you become a "contributor"... The income of validators/miners is also closely tied to this. Anyway, I'm now more concerned about whether the confirmation is stable and whether it can be checked on-chain, rather than listening to some fancy explanations; for now, that's it, continuing to dive.
