The hacker's nightmare: Money is on the chain, but you can't move it

This time, the most exciting part of the KelpDAO incident isn't the attack itself, but the outcome.
The hacker succeeded, but not completely—funds were locked, and operational space was immediately reduced to zero.
It's like you stole a sports car, only to find the steering wheel was removed.
The question is:
Why was Arbitrum able to do this?
The answer isn't complicated: ecosystem collaboration + governance mechanism + technical contingency plans.
In the past, everyone thought L2 was just "cheaper Ethereum," but now it’s beginning to show another capability—fast governance execution.
This also brings up a controversial point:
"Is on-chain freezing against decentralization?"
Honestly, this question is somewhat idealistic.
The real market has never been "completely free," but "freedom + rules."
Without rules, hackers are the biggest winners.
From a game theory perspective, this freezing directly changes the attack ROI model:
Risks increase, returns decrease, and the time window shortens.
And these three points are the most effective ways to combat hackers.
On a deeper level, this is actually reshaping the trust structure of Web3—
From "code is law" to "code + governance collective action."
To conclude:
The most ruthless thing on the chain isn't the hacker, but—your system that you thought was secure suddenly starts fighting back.
