Chainlink takes the cryptographic truth generated by blockchains & extends it to off-chain computing. This is done by enabling users to definitively code how oracle networks should
-form consensus about an off-chain event
-prove the integrity of their off-chain computation
Chainlink获取区块链生成的加密真相&；将其扩展到链外计算。这是通过使用户能够明确地编写oracle networks应该如何实现的代码来实现的
-就链外活动形成共识
-证明其链外计算的完整性
