## Data Feed Aggregation

Data feed aggregation is the process of combining data from multiple independent sources to produce a single, representative price. By pulling data from various exchanges, the oracle network minimizes the influence of any single corrupted source.

This approach is central to the design of robust decentralized finance applications. The aggregation algorithm often employs median-based calculations to ignore outliers that might be the result of errors or malicious intent.

This statistical method provides a reliable price feed even if a minority of sources are compromised. It is the primary defense against localized price manipulation.

As the number of sources increases, the network becomes more resilient to systemic failures.
