How do smart contracts know off-chain prices? No worries—the class representative is here to explain:
Smart contracts can’t fetch off-chain data, such as token prices or weather, on their own. They rely on oracles to write that data onto the blockchain.
If an oracle is manipulated, protocols that use its prices may liquidate positions at the wrong price. That’s why diverse data sources and decentralized nodes are crucial.
There’s no exam for this lesson, but the market may spring a pop quiz.
