## What is the Mechanism of Price Data Aggregation?

Price data aggregation involves collecting real-time price information from various exchanges and liquidity sources. This process calculates a single, representative price by applying a methodology such as a volume-weighted average price (VWAP). The mechanism aims to filter out noise and prevent manipulation from single data points.

## What is the Integrity of Price Data Aggregation?

The integrity of aggregated price data is paramount for decentralized finance protocols and derivatives platforms. A reliable price feed ensures accurate collateral valuation and fair settlement of contracts. Without robust aggregation, protocols are vulnerable to exploits where an attacker manipulates a single exchange price to trigger favorable outcomes.

## What is the Application of Price Data Aggregation?

Derivatives platforms use aggregated price data as the reference point for calculating margin requirements and executing liquidations. Options contracts rely on this data for accurate strike price determination and settlement calculations. The use of aggregated data enhances the overall security and fairness of financial derivatives.
