In on-chain finance, the real challenge has never been at the moment of product launch, but in every second after launch—no matter how the market fluctuates or trading volume surges, rule enforcement must remain consistent. The intricacies involved are actually quite profound.

Price flash crashes, data delays, abnormal value detection inaccuracies—these seemingly minor issues, once they occur, directly impact the fairness of liquidation and risk control. If the data at the input layer is distorted, no matter how sophisticated the backend mechanisms are, they can't save the situation, and ultimately, the blame falls on this.

The value of oracle services lies precisely here—delivering market data to the blockchain more timely and accurately, enabling protocols to maintain stable execution standards even in extreme market conditions. For users, this means fewer unexpected liquidations; for developers, it frees up time from "incident review and emergency fixes," allowing genuine focus on product innovation.

Mastering this aspect is essential for a more stable ecosystem.
