Recently, I keep seeing the term "modular chain," and honestly, the most direct change for ordinary users isn't some fancy architecture diagram, but rather: you might not even know which chain you're actually using.

Clicking on it in your wallet, the settlement/data/execution are separated behind the scenes, and if done well, it results in cheaper and smoother experiences; if done poorly, it’s cross-chain, bridge-to-bridge, and when errors happen, you don’t even know who to blame.

Another point is that on-chain data tools and address labels have recently been criticized for being outdated or misleading. I can really understand this: after modularization and multi-layer settlement, address behaviors are more like "puzzles."
If you only look at the label of a certain layer, it’s very easy to misjudge whether someone is a whale or just running errands.
In the future, I’ll pay more attention to governance proposals: which layer of the project is collecting fees, and where does accountability fall if something goes wrong.
(When I talk about these things in the group, it feels like I’m translating product manuals for everyone…)
