Lately, parallelization/sharding has been a hot topic, with the narrative unfolding like a geometric pattern, looking very beautiful. But I now tend to focus on two very basic things: where are the assets actually locked, and how to exit if something goes wrong.

Sharing security, yield stacking, and being criticized as "nested" or "layered" — basically, the more layers you stack, the longer the path becomes. If any layer gets stuck, exiting is no longer the simple button you thought it was.

When I was a beginner, I misunderstood: as long as it sounds like "shared security," it’s more stable, and yield stacking just means earning a bit more.
Now I understand: security is not just a slogan; it’s about who can move your funds and whether you can gracefully exit in bad situations. Yield is just a compensation for the complexity and tail risks you bear.
Let’s keep it at that — I’d rather have less excitement.
