Recently, parallel processing and sharding have been quite the hot topics. It seems that as long as the "throughput goes up," everything is solved. But I’m actually more concerned about two practical issues: where to store assets safely, and whether I can smoothly withdraw back to the main chain or switch to another platform if something goes wrong. To put it simply, don’t just look at the cheap and fast options; first ask yourself if your exit path might get blocked.

These days, I’ve also seen many people complain about miner/validator income, MEV, and whether the ordering is fair or not. It feels like everyone isn’t really against the technical narrative but is afraid of being at the end of the queue and getting exploited. Anyway, when I launch a new chain, I’ll first try small amounts to make a few transactions back and forth, check out the bridge and proof window, challenge period, and so on. Don’t wait until the excitement dies down and find the fee collector standing at the door.
