驱动未来的智能合约

“可组合性的其中一个好处是无需所有东西都亲手打造。Chainlink预言机非常好用，而Chainlink也采用了可组合性的概念，这是至关重要的。”

Stani Kulechov

CEO

“我们做了尽职调查，看了各种预言机解决方案......Chainlink绝对是最成熟的。每次我们跟Chainlink团队打交道，都会惊讶于他们团队的专业程度，这让我非常有安全感。”

Justin Moses

CTO

“这款产品基于区块链技术打造，利用了Arbol的智能合约以及Chainlink提供的去中心化天气数据，为用户提供了独一无二的价值主张。”

Siddhartha Jha

CEO兼创始人

"Public network infrastructure provisioning has been a core business model of telco companies for decades. Providing critical Web3 infrastructure by running Chainlink oracle nodes has enabled new revenue streams and opened the door to Web3 opportunities."
