## Price Feed Aggregation Models

Price Feed Aggregation Models are the methods used to combine data from multiple sources into a single, reliable price. These models often use techniques like medianization or weighted averages to filter out outliers and malicious data points.

By using multiple sources, the protocol becomes less dependent on any single feed, which enhances security. The choice of model can significantly impact the responsiveness and accuracy of the price feed.

More complex models might provide better protection against manipulation but can also introduce latency. These models are the heart of decentralized oracle networks.

They are essential for ensuring that the protocol's economic state remains aligned with the real-world market. Constant refinement of these models is necessary to stay ahead of evolving attack vectors.

It is a critical aspect of building robust financial derivatives.
