The 3 seconds of network congestion are enough to cause a perfect risk control system to collapse instantly.

No matter how sophisticated the smart contract logic is, it cannot escape a physical dilemma—oracle delay. The prices you see on your screen are not the "real-time prices" on the chain. When a black swan event truly occurs (such as a major coin suddenly crashing 50%), the blockchain network immediately plunges into terrifying congestion, with Gas fees skyrocketing to absurd levels.

The most frightening thing happens at this moment: the spot price on exchanges has already bottomed out, but the on-chain oracle, due to network congestion, is still feeding data from 3 seconds ago. It is this brief 3-second window that becomes the hunting ground for hackers and arbitrage bots. They exploit this time gap, using outdated and inflated price data to borrow assets far exceeding their actual value within DeFi protocols. Or even more ruthlessly, they jump ahead of automatic liquidation bots and directly wipe out your entire position.

This is a systemic vulnerability that code cannot fix. No matter how strict your LTV ratio settings are, they cannot prevent the oracle from "blinding" during extreme market conditions. For users with large positions, this is not just a slippage issue—it's a matter of life and death. If your position management does not account for the "3 seconds of network explosion," then what you think is a solid safety cushion is actually just paper-thin.

Trust in big-name oracles like Chainlink or Pyth is also pointless. When network throughput is maxed out, any brand endorsement cannot save high-leverage positions. The real risk control logic should be: always assume the oracle will fail in the next second, rather than betting on it remaining accurate forever. In the face of extreme market conditions, conservatism is the only way to survive.
