5月30日是Chainlink在以太坊主网上线三周年的日子。自从主网上线以来,Chainlink在全球开发者、研究者、贡献者、数据提供商、节点运营商以及社区成员的帮助下,已经发展成了Web3世界中不可或缺的预言机基础设施。 Chainlink在2019年5月30日发布,当时我们只有三个预言机节点,传输一个ETH/USD喂价。在那之后的三年里,Chainlink不断成长,开发了将近一千个独立的去中心化预言机网络,覆盖12条区块链和layer 2网络,并为智能合约保障了数百亿美元的价值。 自从Chainlink发布以来,区块链预言机有了显著发展。Chainlink被许多人视为DeFi行业的“隐形支柱”,业务除了价格预言机以外,更是拓展至了一系列信任最小化服务,为智能合约的创新和应用提供动力。 为Web3提供关键的预言机支柱:从数据到计算解决预言机问题Chainlink主要聚焦于解决区块链预言机问题,实现智能合约的巨大潜力。要解决这个问题,就要安全地将链上环境与链下世界连通起来。DeFi、NFT和参数型保险等Web3世界中主流的垂直领域如果无法可靠地访问市场数据、体育比赛数据和天气数据等各种链下数据,就无法真正取得发展。而这就需要通过可靠的预言机解决方案来实现。 要理解Chainlink预言机对Web3的重要意义,归根到底就必须理解链上和链下的根本差异,以及混合型智能合约如何以创新的方式连通这两个世界。 提供创新的信任最小化服务Chainlink拥有前沿的预言机技术,拓展了预言机的功能,不仅可以可靠地传输数据,还能安全地开展链下计算。Chainlink提供了包括可验证随机数和交易自动化在内的一系列信任最小化服务,帮助开发者打造更加安全、高成本效益以及功能完备的应用,比如动态NFT、P2E游戏(play-to-earn)、Yield farming协议、stablecoin以及DAO。 在网络和生态方面达成的里程碑经过了三年的不懈努力,Chainlink达成了许多里程碑,以下是其中一些最能代表Chainlink对Web3影响力的突出成就: 赋能DeFi应用 Chainlink被美国银行评为推动DeFi锁仓量增长的关键动力,驱动了DeFi经济中的众多市场和顶尖协议,其中包括Aave、Compound、dYdX、Frax、Liquity和Synthetix。请阅读《Chainlink Price Feeds如何保障DeFi生态安全》。 提供多链支持 Chainlink预言机可以兼容任何区块链,目前已原生集成至超过12条区块链和layer 2网络,其中包括Arbitrum、Avalanche、BNB Chain、以太坊、Fantom、Gnosis Chain、Harmony、Heco、Moonriver、Moonbeam、Optimism、Polygon以及Starkware。 向链上传输创新数据集 Chainlink预言机不仅可以传输各种加密资产喂价,还可以安全地传输大宗商品、外汇汇率、指数、天气数据、体育比赛数据、竞选结果以及航班信息等数据。 开展链下计算 Chainlink可以为智能合约实现安全的链下计算,其中包括通过Chainlink VRF生成防篡改且可验证的随机数;通过OCR(链下报告)协议提升效率;以及通过Chainlink Keepers以去中心化的方式可靠地实现自动化。 招募更多开发者 Chainlink在生态中组织开展了各类活动,其中包括SmartCon、黑客松、新手训练营、社区激励计划以及Startup with Chainlink计划,迅速吸引了众多Web3开发者,使社区规模不断壮大,而且还帮助了许多初创项目从原型开发一路走到主网上线。 集成了超过1320个项目 Chainlink生态成员既包含DeFi行业的顶尖项目,也包含希望参与智能合约经济的领先全球企业,比如AccuWeather、Amazon Web Services、Google Cloud, Swisscom、美联社以及T-Systems等。 开展智能合约研究和创新工作 Chainlink一直坚持不懈地展开Web3研发工作,比如发布OCR协议,提升数据聚合成本效益;在《Chainlink 2.0白皮书》中提出超线性质押模式(superlinear staking model);以及计划发布CCIP,保障跨链消息传输的安全性。 通过混合型智能合约实现积极的社会影响
