## What is the Data of Oracle Aggregation?

Oracle aggregation involves collecting data from multiple independent sources to establish a robust and reliable price feed for decentralized applications. This process mitigates the risk of relying on a single data source, which could be vulnerable to manipulation or technical failure. The aggregated data is then used to trigger smart contract functions, such as liquidations or settlement calculations.

## What is the Security of Oracle Aggregation?

The security of decentralized finance protocols heavily depends on the integrity of oracle aggregation. By combining data from diverse sources, the system increases the cost and complexity required for an attacker to manipulate the price feed. This redundancy protects against single-source exploits and enhances the overall resilience of the protocol.

## What is the Mechanism of Oracle Aggregation?

The aggregation mechanism typically involves a weighted average or median calculation of data points submitted by multiple oracles. This methodology ensures that outliers or malicious data submissions have minimal impact on the final price feed. The design of the aggregation algorithm is critical for maintaining accuracy and preventing manipulation in volatile markets.
