The term "modular chain" sounds like "disassembling a car into engine + chassis + tires for individual optimization," but what actual changes does it bring to us end users? My personal experience boils down to two points: first, the same operation is less likely to be "slipped as a human error," making routing smarter and more controllable; second, applications can switch underlying layers more quickly, for example, moving from chain A today to chain B tomorrow for DA/settlement, without having to start from zero cold boot each time.

But don’t overhype it; frankly, you'll still encounter "bridges," "latency," and "funds not arriving" anxiety—it's just that it spreads the blame: whoever is responsible for data is responsible for settlement, making issues easier to pinpoint.

Recently, I saw the collapse of the blockchain game economy—inflation + studio + coin price spiral—and it feels like modularity at most makes it easier for you to switch tracks, but can't fix the fundamental bad design. Forget it, to put it plainly: for ordinary people, it might just be a smoother experience and more frequent migrations, but don’t expect it to automatically make you money.
