Node operators

Overview

Chainlink node operators are the entities running the oracle infrastructure (hardware and software) that powers and secures every oracle network running on the Chainlink Network.^[1]

In depth

EDIT They are powered by independent, highly reputable, and geographically distributed node operators, which helps to ensure the reliability of the data returned. The ETH / USD feed, for example, currently utilizes 31 separate oracles, or sources of information, to determine the current trusted answer for the price of ETH in USD.

Why do we need 31 sources for the same information? Using multiple sources to aggregate a validated response means that there can be no single point of failure and protects against data tampering.^[2] EDIT
