Recently, the narrative of parallel processing and sharding has become popular again. The timeline looks pretty exciting, but my obsessive-compulsive tendencies only focus on two things: where to place assets and whether they can exit. No matter how fast the on-chain transactions are, if the contract permissions, upgrade pathways, or cross-chain bridge exit routes get clogged, the experience shifts from "smooth" to "frozen."

These days, I've also seen many people complaining about miner/validator income, MEV, and unfair ordering. Basically, you think you're confirming transactions, but you're actually queuing up and competing for positions... The noise is really loud. My noise-canceling strategy is very simple: I only look at two charts—large address "transfers/receipts + interaction targets." If there's no exit action, I consider it as not happening. That's how I'll proceed for now.
