Chainlink Aggregator

A Chainlink Aggregator is a decentralized oracle contract that collects price data from multiple independent nodes and aggregates them into a single, reliable price feed. By taking the median of many individual node responses, the aggregator filters out outliers and malicious data, ensuring high accuracy and tamper resistance.

This process mitigates the risk of a single point of failure or manipulation by a bad actor. These aggregators are essential for DeFi, providing the trusted reference price for thousands of trading pairs.

They operate based on predefined update triggers, such as a percentage change in price or a specific time interval. This structure provides the necessary trust layer for complex derivatives like options and synthetic assets to function securely.
