What Is a “Medianizer” and How Is It Used in Decentralized Oracle Systems?

A medianizer is a smart contract function that takes a set of data points (e.g. prices submitted by multiple Oracle nodes) and calculates the median value, which is then published as the official, aggregated price feed. It is a critical component of decentralized Oracle systems because it provides a single, robust, and manipulation-resistant price that the derivative smart contract can trust for its execution logic.
