Recently, I saw people discussing a bunch of terms like "data availability, ordering, finality" — actually, you just need to follow one line: what you do on the chain, whether others can see it + verify it + how long it takes to be truly finalized. Data availability is like "whether the ledger is publicly published"; ordering is "who says what first and who follows"; finality is "whether this transaction will be overturned." For my small funds doing L2 tasks, I care more about the last one — anyway, I just want to profit and then withdraw, not stuck in a situation where it takes forever to settle or might roll back, that kind of mentality is too exhausting.

These days, I also came across social mining, fan tokens, and phrases like "attention is mining"... Honestly, attention can indeed turn into money, but who holds the ordering rights, whether the data is truly transparent and open — many projects don’t explain this clearly and just ask you to go engage, only to find out in the end that they’re just collecting data and traffic for others. I’m not saying all of it is bad, but I find it a bit annoying how these terms are packaged so fancy, with all the risks relying on user awareness — let’s leave it at that for now.
