将您的智能合约接入链下数据

智能合约本质上是与世隔绝的

Blockchains are highly secure and reliable networks for value exchange but lack the functionality to natively fetch external data or send data to offchain systems in a manner that retains end-to-end tamper-resistance.

Chainlink将智能合约与现实世界相连

Through the use of secure oracles, Chainlink extends the functionality of blockchains by connecting smart contracts to real-world data, events, payments, and offchain computation in a highly tamper-resistant and reliable manner.
