## Decentralized Oracles

Decentralized oracles are networks of independent nodes that aggregate data from multiple sources to provide a single, reliable truth to smart contracts. By removing a single point of failure, they make the data feed much harder to manipulate or censor.

In the context of derivatives, they are used to ensure that liquidations are triggered by genuine market movements rather than oracle errors. These systems often use cryptographic signatures to prove the origin of the data and economic incentives to ensure node honesty.

They solve the problem of trusting a single entity with sensitive financial information. As the complexity of on-chain derivatives grows, the reliance on robust, decentralized oracle networks becomes even more critical.

They are a fundamental layer of the decentralized finance infrastructure that enables complex cross-chain interactions.
