树立了预言机行业的标准

Chainlink将智能合约接入真实世界的数据和链下计算资源，极大提升了智能合约的功能；并同时保留了区块链技术核心的安全性和可靠性。

What is TVE?

Transaction value enabled (TVE) is a Web3 metric that measures the aggregate monetary value of transactions facilitated by a protocol over a given time period. TVE is calculated by taking the sum of the USD value associated with each transaction that passed through a protocol during a given period.

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。”

“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。”

“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。”

"许多人忽视了预言机对智能合约应用的重要意义。我们在现实中反复验证了一点，那就是智能合约的安全性是由它的预言机的安全性决定的。因此，我们团队的重要任务就是找到一个预言机解决方案，能够满足Trader Joe对于安全的要求。"
