Lately, I keep seeing a bunch of new L1/L2 projects starting to issue incentives to boost TVL, and old users complain "mining, selling." I think people shouldn't get confused by the terminology; just focus on one main thread: where the money and transactions "go first," who makes the rules, and when it counts. Data availability, simply put, is whether your teacher can see your homework; ordering is just about queuing and cutting in line; finality is whether you can change your mind after the transaction is finalized. When incentives kick in, everyone cares more about "whether they can run first," and once the ordering and finality are clear, the on-chain path becomes very honest. Last night, my mom asked me: "Why do you keep looking at these nonces all day…?" I said it's like watching people pass through checkpoints and get stamps—if someone keeps turning back at the same checkpoint, they probably have something to hide. Anyway, I’d rather go slow now and make sure I understand whether you can undo the transactions if something goes wrong on this chain.
