美联社使用区块链来打击假选举新闻

2020-10-19 12:55

 

区块链公司Everipedia宣布了与美联社(AP)和Chainlink的合作,后者是一家去中心化的甲骨文网络公司。该项目将使美联社能够在区块链上安全地、透明地发布美国大选电话。然后,可以使用区块链来验证数据的合法性。


如今,新闻错误信息司空见惯,像Facebook和Twitter这样的大型科技公司试图解决这个问题,但收效甚微。


就区块链用例而言,验证数据是准确的并且没有被操作的能力似乎是非常有效的。特别是因为美联社自1848年以来就在地方和国家层面报道了美国大选的长期记录。

它是如何工作的


美联社使用大量的特约记者来查询当地的选举数据——竞选电话。


与此同时,区块链的全部意义在于它们相对安全,因为有大量的节点验证交易。但是如何确保数据是有效的呢?答案是对数据进行加密签名,以确认它来自正确的人。


但这并不能保证最终的新闻是准确的,因为有人可能会侵入美联社的核心系统,或者用于签署数据的密钥可能会被盗。但除此之外,它比那些只发电子邮件的人要可靠得多。


在技术层面,出于安全原因,区块链智能合同被设计成相对封闭的。所以他们使用神谕与外界沟通,通常是获取价格信息、天气数据,或者在这种情况下,获取新闻。链链是一个受欢迎的公共区块链安全神谕供应商。它连接到传统的api,并以一种安全的方式将数据提供给多个公共区块链。它提供的最大服务之一是确保API不会停止向区块链提供数据。因此,链连接被用于AP oracle。


这并不是区块链在新闻界的第一次尝试。去年,《纽约时报》推出了基于区块链的新闻来源项目,利用分布式账本技术(DLT)来核实媒体来源和潜在的编辑信息,以解决虚假信息问题。它最近宣布为该项目建立了一个区块链原型。


欧洲也开始指望区块链来阻止假新闻。今年早些时候,意大利新闻机构ANSA宣布与EY合作开发了区块链系统来追踪新闻。这个解决方案允许读者在ANSA自己的网站上、它的附属出版物上以及在其他地方(如社交媒体)发表的文章上查看新闻的来源。

 

Blockchain firm Everipedia announced its collaboration with news agency The Associated Press (AP) and Chainlink, a decentralized oracle network. The project will enable AP to distribute U.S. election race calls onto a blockchain securely and transparently. And in turn, the blockchain can be used to verify the data is legitimate.

Nowadays, news misinformation is commonplace, with major technology companies like Facebook and Twitter attempting to address the issue to little avail.

In terms of blockchain use cases, the ability to verify that data is accurate and has not been manipulated seems like a pretty valid one. Especially since the Associated Press has a long track record of covering the U.S. elections since 1848 at both local and national levels.

How it works

The Associated Press uses a large number of stringers to call in local election data – the race calls.

Meanwhile, the whole point of blockchains is they are relatively secure because numerous nodes validate transactions. But how can you ensure the data is valid? The answer is to cryptographically sign the data to confirm it originates from the right person. 

That’s still not a 100% guarantee that the resulting news will be accurate because someone could hack the AP’s core systems, or the keys used to sign the data could get stolen. But barring that, it’s significantly more reliable than someone just emailing the calls.

At a technical level, blockchain smart contracts are designed to be relatively insular for security reasons. So they use oracles to communicate with the outside world, often to get price feeds, weather data, or in this case, the news. Chainlink is a popular provider of secure oracles for public blockchains. It connects to conventional APIs and feeds the data to multiple public blockchains in a secure manner. One of the biggest services it provides is ensuring the API doesn’t stop feeding data to the blockchain. Hence Chainlink is being used for the AP oracle.

This isn’t the first attempt to use blockchain in the news world. Last year, the New York Times launched its blockchain-based News Provenance Project to tackle misinformation, using distributed ledger technology (DLT) to verify the media source and potential edits. It recently announced it built a blockchain prototype for the project.

Europe has also started looking to blockchain to stop fake news. Earlier this year, Italian news agency ANSA announced it developed a blockchain system for tracking news in partnership with EY. The solution allows readers to check the origin of the news on ANSA’s own site, its affiliated publications, and articles published elsewhere such as social media.
