Recently, everyone has been interpreting ETF capital flows, U.S. stock market risk appetite, and cryptocurrency market fluctuations as if they are all tightly linked, which made me want to uninstall the app... But thinking about it, since I tend to pick up on the fringes, if I really uninstall, I might miss a bunch of forgotten claims. Never mind, I’ll hold on for now.

Honestly, those terms like “data availability, ordering, finality” sound intimidating, but you only need to follow one main thread: who is keeping the records of your transaction’s “process” and “result,” who can prove it, and how long it takes to truly finalize. Data availability = don’t just send a receipt, it’s best to also include the details; ordering = who gets to decide the queue, how costly is it to cut in line; finality = don’t say it’s successful today and then crash again tomorrow. Don’t get confused by the terminology—if you understand these three things, you won’t fall into many on-chain traps so easily.
