I'm not very good at... making a bunch of nouns sound cool, but these days I keep thinking that actually, you just need to follow one line: money entering the chain, how the chain queues, and whether it really counts in the end. Data availability, simply put, is whether you can get complete data to verify; ordering is who goes first and who goes later, deciding if you've been jumped in line; finality is whether it will change its mind again after a while. Don't just look at "throughput" and "low fees," if you loosen these three things, the experience might still be smooth, but the risks are quietly piling up.

Recently, the wave of AI Agents and automated trading is also quite obvious, the narrative is being hyped up, but I'm more concerned about their security boundaries when interacting with the chain: giving too much permission, signing too casually, and when something goes wrong later, there's no time to react. Anyway, I prefer to be a bit slower, willing to miss the excitement, rather than becoming a test subject in places where "finality" hasn't been firmly established.
