Chainlink中国区负责人条子哥昨天给我分享了一篇海外英文文章,让我看看,今天晚上下班后我决定把它翻译成中文,给 Chainlink 更多中国社区的小伙伴阅读。

我会给出一段英文原文和一段我的中文翻译。文章比较长,今天只翻译上半部分。非计算机专业出身,原创翻译不易,有个别专业术语翻译如果错误,欢迎指出。

感谢点赞,评论。


Chainlink: Beyond Price Feeds and Data Delivery

喂价和数据传输之外的Chainlink(上)

Chainlink has established itself as the industry standard oracle solution for DeFi, launching a market-leading number of Price Feeds live in production that are widely used to secure $4B+ in value for DeFi leaders like Synthetix, Aave, yEarn, and more. The need for price feed oracles is obvious, as DeFi is the first smart contract market to truly thrive and nearly all DeFi applications require aggregated price data to secure and settle financial contracts. The market for financial data is massive, with derivatives alone being a near one quadrillion dollar industry that’s almost entirely settled by price feeds, let alone the numerous other capital markets worth tens of trillions of dollars like real estate, commodities, stocks, and more.


Chainlink已经确立成为为DeFi(去中心化金融)提供预言机解决方案的行业标准,,在该领域实时提供了行业领先的大量喂价服务,广泛应用于DeFi行业领头项目,例如:Synthetix, Aave, yEarn等,确保了超过40亿美元资产的价值。对喂价预言机的需求是显著的,因为DeFi是第一个真正爆款的智能合约市场,同时几乎所有的的DeFi应用都需要聚合价格数据来确保和处理金融合约。市场对于金融数据的需求是巨大的,单单金融衍生市场就有接近一千万亿美元几乎全部由喂价处理,这还不算其他数万万亿的资本市场,例如:房地产,大宗商品和股票市场。

However, to say Chainlink is only useful for price feeds is completely overlooking the much broader application and functionality of oracles, similar to those that thought the Internet was only useful for email. Chainlink can extend the connectivity of smart contracts to every off-chain data source and system in existence, as well as perform numerous types of computation on such data before it’s delivered to its destination. There is truly an unbounded amount of data and types of computational services that the Chainlink Network can provide and price feeds are truly just the tip of the iceberg.


然而,说Chainlink仅仅只对喂价有用是完全忽视了预言机更广泛的应用和功能,类似于那些曾经觉得互联网只能用来发电子邮件一样。Chainlink可以延伸智能合约的连通性到任何已经存在的链下数据资源和系统,同时在将数据运输到其目的地之前,Chainlink可以基于这些数据执行大量不同种类的运算。Chainlink网络可以提供有大量数据和各种运算服务,喂价真的是冰山一角。


The Chainlink iceberg of oracle services consists of several categories:
Chainlink预言机服务包含以下不同种类:

Price Feeds — Chainlink’s pre-built decentralized price feeds provide DeFi applications a real-time stream of financial market data, including exchange rates for cryptocurrencies, stablecoins, commodities, indices, stocks, fiat currencies, and other key financial datasets.


喂价—Chainlink预建的去中心化喂价为DeFi应用提供了金融市场实时数据流,包括加密数字货币,稳定币,大宗商品,指数,股票,法币和其他主要金融数据的汇率。

Any Web API — Chainlink oracles are able to connect smart contracts to any open or authenticated API, opening up access to IoT data, bank payments, web APIs, enterprise systems, other blockchains, and virtually any off-chain resource used to create smart contract markets in insurance, supply chain, digital marketing, and various other new industries.


任何网站API —Chainlink预言机可以将智能合约连接至任何开放或者已验证的API,打开接入物联网数据,银行支付,网站API,公司系统,其他区块链数据通道。事实上,Chainlink预言机可以在保险,供应链,数字市场和其他各种新兴产业,连接任何链下资源提供智能合约。

Verifiable RNG — Chainlink VRF (Verifiable Randomness Function) generates a secure source of on-chain randomness that users can independently verify as fair, unbiased, and tamperproof, leading to gaming applications, NFTs, blockchain lotteries, layer-2 protocols, and more that can reliably secure large amounts of value with RNG inputs.


可验证的随机数生成器—Chainlink VRF(可验证随机数)可以产生链上随机安全数据源,用户可以独立验证公平,公正,防止被篡改的数据。应用于游戏应用,NFT(非同质化代币)项目,区块链彩票,二层协议和更多通过随机数生成器输入可靠地确保数据价值。

Off-chain Computation — Chainlink oracles can perform more advanced off-chain computations, leading to an expansion in oracle services such as scalable Solidity computation, blockchain transaction privacy, oracle data privacy/integrity, transaction order fairness, and more.


链下运算—Chainlink预言机可以运行更加高级的链下运算,拓展了预言机服务,例如可拓展的Solidity运算,区块链交易隐私,预言机数据隐私/完整性,交易秩序公平性等等。

Blockchain Abstraction Layer — Chainlink’s continued integration across all the leading blockchains that exist now and in the future, provides enterprises, governments, and data providers with a single integration gateway to connect applications and sell data to every blockchain network, reducing development costs and preventing vendor lock-in.


区块链抽象层—Chainlink持续与现存和将来所有领先的区块链项目整合,为企业,政府部门和数据提供商提供了一个整合入口来连接所有应用,同时将数据卖给所有区块链网络,降低了开发成本,并且防止供应商锁定。

Please note that the infographic is merely a representation of the five primary categories of oracle services listed in a progressively more expansive manner. However, many of these features are likely to be developed in stages with overlapping timelines, not to mention there will be numerous features introduced that we simply can’t imagine today, similar to how Uber and Tinder were largely unimaginable to Internet users in 1994.

请注意这个信息图仅仅用不断发展扩展地方式展示了预言机服务的5个主要种类。然而,多数这些特性都是在重叠的时间性上发展的,没提到的更多预言机特性是我们今天都无法想象的,类似于对于1994年的互联网用户根本无法想象今天Uber和Tinder这样的互联网公司。

P.S. Abstraction Layer,查了资料,还是不懂,只能字面翻译了。请教了田七,他给我的解答:抽象层想表达的是链外应用与公链进行数据交互的时候,可以通过Chainlink实现。这样Chainlink就把这些区块链抽象成一个,也即是对外部应用来说,他们只需要专注与Chainlink交互,就达到了与各个公链交互的目的。有点像是Chainlink成了公链的代理。
