Chainlink (LINK) perpetual market

Chainlink is the leading decentralized oracle network, launched in 2019 to solve a core limitation of smart contracts: blockchains cannot natively access data from the outside world. Its native token, LINK, pays node operators who fetch, verify and deliver off-chain data such as asset prices, and is staked to back the reliability of that data. Chainlink's price feeds became critical infrastructure for decentralized finance, securing lending protocols, derivatives and stablecoins that need trustworthy market prices, and it has expanded into verifiable randomness, proof-of-reserve and its Cross-Chain Interoperability Protocol for moving data and value between blockchains. Founded by Sergey Nazarov, Chainlink has pursued partnerships with major financial institutions exploring tokenization. Because so many protocols depend on its feeds, it is often described as the connective tissue between blockchains and real-world data.
