What Is the “Data Aggregation” Process in a Decentralized Oracle Network?

Data aggregation is the process of collecting price data from multiple independent data providers and external sources. These individual data points are then combined and validated using a median, mean, or other statistical method to produce a single, robust, and tamper-resistant final price feed.

This redundancy and aggregation mitigate the risk of a single point of failure or a malicious individual provider.
