## Chainlink Aggregator Nodes

Chainlink aggregator nodes are specialized infrastructure components that collect and verify data from multiple independent sources before delivering it to a smart contract. These nodes form the backbone of decentralized oracle networks, ensuring that price feeds are resilient against single-node failures or malicious reporting.

By aggregating data, they smooth out outliers and provide a reliable, single price point for protocols to use. Their operation is governed by incentive structures that reward honesty and penalize poor performance.

This architecture is fundamental to the security of many high-value DeFi protocols. It effectively creates a robust, industry-standard mechanism for trusted off-chain data delivery.
