Chainlink decentralized oracle networks support advanced smart contracts on any blockchain.

What is Chainlink?
Chainlink is a DeFi oracle that gives Ethereum-based smart contracts access to real-world data and off-chain computation. Their products include data feeds, Verifiable Random Numbers (VRF), calling external APIs, and automated contracts. The protocol is meant to be able to verify whether the parameters of a smart contract with real-world data are independent of stakeholders.
