Recently, everyone has been talking about sharding/parallelism again, feeling like every so often there's a wave of "repeating the new narrative." It's lively, but for someone like me who loves watching internal conflicts, I just want to ask first: if something goes wrong, how do you retreat? Can the funds be smoothly withdrawn? To put it simply, everyone argues over how to change parameters, who holds the permissions, but in the end, the assets are the ones that suffer.

Scenes like being hacked through cross-chain bridges or oracles suddenly reporting outrageous prices and then the whole network waiting for "confirmation" have become tiresome after seeing them so many times. For me, the real signals are not TPS or the curve on the PPT, but whether: permission changes leave traces, who can decide to roll back/pause when problems occur, and how many gates you have to go through to withdraw from the protocol... Anyway, I want to understand the exit path first, and the drama can be enjoyed slowly.
