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。”

"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."

Chainlink’s new platform lets web3 projects connect to Web 2.0 systems like AWS and Meta

Chainlink, a web3 services platform, is launching a self-service, serverless platform to help developers connect their decentralized applications (dApps) or smart contracts to any Web 2.0 API

Base Lead Jesse Pollak Says Chainlink Is Key To Building “The Ultimate Bridge” Between Web2 And Web3

Last week at ETHDenver, Coinbase and Chainlink announced that Chainlink Price Feeds are live on testnet for the newly launched layer-2 network, Base.

Chainlink, TrueUSD Start Real-Time ‘Mint Lock’ Verification of Stablecoin Reserves

The key is to get information from the bank account where the stablecoin’s reserves are kept to the blockchain-based smart contract that controls issuance of new TUSD.
