An experienced DeFi player once shared a frustrating story with me. Last year, he carefully set up a lending protocol, including stop-loss orders, but due to a 2-second delay in the oracle, his entire position was forcibly liquidated. Overnight, he lost half of his hard-earned down payment. Staring at the liquidation record, he kept asking me, "Isn't blockchain supposed to be the most transparent? How come it can't even guarantee an accurate price?"

This question hits the most painful point in the entire DeFi industry.

To be honest, most people don't realize how serious the problem really is. The lending platforms, trading tools, and leverage contracts you use are all asking the same question every second: What is the current ETH price? All these answers come from the oracle. It seems fine on the surface, but underlying currents are surging.

A 2-second delay? During market volatility, that's enough to cause incorrect liquidations. Missing a decimal point in data? The lending protocol might mistakenly think your collateral is insufficient and liquidate your position. Even more terrifying, if the data is manipulated or polluted, the entire DeFi ecosystem could be drained.

You spend effort studying candlestick charts and repeatedly testing stop-loss parameters, but you might lose out at an unseen link—that's where DeFi is most vulnerable.

**Change is happening**

Leo Su and Simon Shieh, developers with technical backgrounds, sketched a bold idea on a whiteboard: instead of making oracles just messengers, why not turn them into data "bodyguards" that verify each piece of information?

In 2024, this idea is becoming reality, reshaping the trust foundation of DeFi.

Traditional oracles are simple and crude—they just transmit what they hear, with little validation in between. The new generation of solutions introduces multi-layer verification mechanisms. Imagine each price data point passing through double checks, plus an AI quality inspection layer. Fault tolerance mechanisms are in place for delays, and active warning systems detect data pollution.

This is not just an upgrade but a rethinking of the entire oracle architecture. When data carries a "ID card" and a "quality seal," the risk defenses of DeFi become truly robust. Lending protocols, trading platforms, and leverage tools can finally access trustworthy data. Users can sleep peacefully, no longer worried about being inexplicably liquidated due to system errors.

Taking this step will transform the entire DeFi ecosystem.
