How Does a Decentralized Oracle Network Achieve Consensus on a Price Feed?

Decentralized oracle networks typically use a voting or aggregation mechanism among multiple independent nodes. Each node submits its observed data, and the contract calculates a final, aggregated value, often the median or a volume-weighted average.

The consensus is achieved when a supermajority of nodes report data within a specified range, making the final price highly resistant to manipulation.
