## Oracle Services

Oracle services act as decentralized data bridges that provide external, real-world information to smart contracts on the blockchain. Because blockchains are isolated systems, they cannot inherently access data like price feeds, weather conditions, or election results.

Oracles fetch this data from off-chain sources and feed it into the blockchain, allowing smart contracts to execute based on real-world events. In the context of financial derivatives, oracles are essential for triggering liquidations, settling contracts, and updating asset prices in real-time.

The security of an oracle is paramount, as malicious or inaccurate data can lead to catastrophic failures in derivative pricing. Decentralized oracle networks mitigate this risk by aggregating data from multiple independent nodes to ensure accuracy and censorship resistance.
