Node operators

From Chainlink Community Wiki

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

EDIT Chainlink Node Operators (NOPs)—independent entities responsible for deploying onto new blockchain networks, sourcing high-quality data, and providing highly secure off-chain services to consumers with high uptime and reliability. Chainlink NOPs are rewarded for participating in the Chainlink Network based on the number of services and updates they support.
