理解预言机，才能更深入地理解 DeFi 的风险
Onea Network
The blockchain does not automatically know the real-time price of BTC. So, what do DeFi lending protocols rely on to determine the value of collateral?
The answer is: Oracles. 🔗
They are responsible for providing external data to smart contracts, but the data sources, update delays, and anomaly handling mechanisms can all affect the security of the protocol.
Before participating in DeFi, don't just look at the yield, also ask:
🔹 Where does the price data come from?
🔹 How are data anomalies handled?
🔹 Do multiple protocols rely on the same data source?
🔹 How will the liquidation mechanism operate under extreme market conditions?
Smart contracts can automatically execute rules, but the data those rules rely on also needs to be verified.
Understanding oracles is key to gaining a deeper understanding of DeFi risks.
