Chainlink is a decentralized oracle network. It aims to serve as a middleware between smart contracts on smart contracting platforms and external data sources, allowing smart contracts to securely access off-chain data feeds. Chainlink is a decentralized oracle network that enables smart contracts to securely interact with real-world data and services that exist outside of blockchain networks. Chainlink is not a monolithic network like a blockchain but rather an infrastructure and framework for building blockchain-agnostic oracle networks that augment the capabilities of blockchains and layer-2 protocols. Each Chainlink oracle network consists of multiple independent oracle nodes that fetch data from multiple independent data providers, aggregate the data into a single data point, and deliver it on-chain to be consumed by smart contracts. Chainlink's flexible architecture allows for highly configurable oracle networks that can be composed of any selection of node operators and data providers and that use different network parameters such as update frequency, fee payment amounts, and more. Chainlink nodes are operated by professional DevOps infrastructure providers, leading enterprises, and premium data providers who supply smart contracts with access to cryptographically signed data for additional security guarantees. Because of its flexible design, Chainlink can provide any type of data or computation to any smart contract application operating on any blockchain network.
