Many people worry that the biggest danger in DeFi is a sudden price plunge, but the real threat is often not that.

The core issue is: you see a number but have no idea how reliable it is. Price data that only provides the value without any confidence level essentially only does half the job.

Yet now most protocols treat it as a complete instruction—automatic liquidation triggers, automatic position closures, leveraged positions loaded automatically—all mechanically executed. When a collapse happens, people are stunned: "How the hell did this happen?"

You might think the risk comes from obvious collapses? Actually, no.

It often hides in the most ordinary corners:

A data provider suddenly stops updating; an information source responds a fraction of a second slower; the timing of a liquidation logic execution is off by three or five seconds compared to the market rhythm. No obvious bugs, no hacking—just a feeling that something's off.

These kinds of issues never make the headlines, but the costs are real.

An unnecessary liquidation. A position that could have survived is forced to close. Suddenly tightening margin requirements. Only after reviewing do you realize: the most critical data was never recorded on-chain; two seemingly synchronized sources actually operate in different time dimensions; the delay didn't directly break the system but slightly raised the risk threshold.

So risk control teams start to go to extremes:

Refusing to lower discount rates; keeping positions always very low; even with ample liquidity, preemptively assuming the world could collapse at any moment. People call this "caution," but honestly—it's only because the oracle has never provided a true confidence level.
