Last night, I was browsing on the blockchain and got a headache, a bunch of people talking about data availability, ordering, finality—terms that sound like a three-piece set to scare people... It reminded me of the recent incentivization wave on the testnet, where everyone was rushing to earn points while secretly wondering "Will the mainnet issue tokens?" Basically, everyone is gambling: whether the data I submit counts, whether my transaction can be prioritized, and whether it will be rejected and need to be resubmitted in the end.

I can focus on one main thread: the process of "submitting assignments" on the chain. Data availability = can the teacher see it (otherwise, who would believe you wrote it?); ordering = who the teacher approves first (the stuff about queue-jumping and cutting in line is all about this); finality = whether the grade can be changed after grading (if it can be changed, don’t take it too seriously). The terms sound intimidating, but once I think about "does this count or not," it’s not so mysterious anymore. Anyway, I don’t dare get too caught up in the testnet now—points are just snacks, not the main course.
