Recently, everyone has been arguing again about which L2 has higher TPS, lower fees, and more aggressive subsidies... I find it a bit theatrical to watch. Modularization, to put it simply, really only changes two things that end users can actually perceive: how transactions are "pushed into blocks" becomes less fixed, and what you think of as confirmation increasingly resembles a layered promise.

In the past, you could somewhat predict the mempool and packing logic of a single chain, but now execution happens here, ordering happens there, data is sent somewhere else, and occasionally there’s a shared sequencer or something similar. For someone like me who loves to be precise, it starts to get tangled: which queue is my transaction actually waiting in? Where are the boundaries for reorganization and rollback? Slippage, front-running, retries on failure—these small amounts of money might be more real than the official claims of "a few cents cheaper."

Of course, it’s not all bad; at least some chains are beginning to clarify their ordering rules or allow you to choose more controllable submission methods. But the user perception is: at the moment the wallet shows "confirmed," what happens behind the scenes is becoming more of a black box... Forget it, I won’t talk about subsidy wars anymore. I’ll be grateful if I can pay less “slippage tax.”
