## What is the Oracle of Price Feed?

A price feed provides real-time market data to smart contracts, enabling decentralized applications to execute functions like liquidations and settlement based on accurate asset prices. These external data sources, known as oracles, are necessary because blockchains cannot access off-chain data directly. Ensuring a reliable price feed is paramount for the integrity of crypto derivatives protocols.

## What is the Reliability of Price Feed?

The reliability of price feeds is critical for risk management in options trading and derivatives. Inaccurate or manipulated data can lead to unfair liquidations or incorrect contract settlement. Decentralized protocols mitigate this risk by aggregating data from multiple sources to prevent single points of failure and increase resistance to market manipulation.

## What is the Risk of Price Feed?

Price feed manipulation, or oracle attacks, represents a primary vector of risk in DeFi derivatives. Attackers attempt to skew the reported price to gain an advantage in leveraged positions. Robust price feeds must incorporate mechanisms that filter out outliers and prevent flash loan attacks from temporarily distorting market data.
