## Oracles and Data Reliability

Oracles are third-party services that provide external data to smart contracts, enabling them to execute based on real-world events. In the context of derivatives, oracles provide price feeds for assets like Bitcoin or Ethereum, which are essential for calculating margin requirements and liquidation thresholds.

The reliability of this data is critical; if an oracle is compromised or manipulated, it can trigger erroneous liquidations and lead to massive financial losses. This risk is known as the oracle problem, and it is a major focus of research in blockchain security.

Protocols often use decentralized oracle networks to aggregate data from multiple sources, reducing the risk of a single point of failure. Ensuring high-fidelity data is a fundamental requirement for the stability of derivative markets.
