Chainlink
Chainlink (LINK) is a token that powers a decentralized oracle network. Oracles deliver real-world data (like prices, weather, or sports scores) to blockchains so smart contracts can react to outside events. LINK is used to pay node operators who provide this data securely, making Chainlink a key bridge between blockchain systems and the real world.

Technology & Use Case
Blockchains can’t access external data by themselves. Chainlink solves this with a decentralized network of oracle nodes that fetch and verify off-chain information. This enables smart contracts to trigger based on real-world events — for example, paying out insurance if a flight is delayed or settling DeFi trades using reliable market prices.
Origins & Team
Chainlink was founded by Sergey Nazarov and Steve Ellis in 2017. Nazarov, a serial entrepreneur in the blockchain space, became the public face of the project. Chainlink quickly grew into the leading oracle provider in crypto, offering tools that developers across blockchains could plug into their apps.
Ecosystem & Partnerships
Chainlink is widely integrated across DeFi, NFTs, insurance, and gaming. Major DeFi protocols like Aave, Synthetix, and Uniswap rely on its price feeds. Partnerships extend to enterprises like Google Cloud, SWIFT, and Oracle. As blockchain adoption grows, Chainlink continues to expand its role as the “data backbone” of Web3.
