The biggest change that modular blockchains bring to ordinary users isn't actually that dramatic: you might not suddenly "understand the architecture," but you'll more frequently jump back and forth between different L2s, and the experience of good or bad is more like switching between different "routes." Whether it's cheap or expensive, fast or slow, on the surface it's a TPS and fee debate, but underneath it's often about where the data is stored, who queues up, and how the final settlement is handled after breaking down these trade-offs.

To put it simply, modularization breaks apart the previously fixed tasks within a single chain, making "latency" and "ordering" more noticeable: sometimes transfers are instant but final confirmation takes time, sometimes fees are low but crossing over requires paying an extra fee, and you also have to worry about bridge and routing hiccups. For someone like me who loves paying attention to details, my final advice is quite simple: don't just look at the advertised maximum TPS, when actually using it, focus on three things—perceived transaction speed, cross-chain hassle, and whether you can safely recover your funds if something goes wrong. That's all for now.
