自从上一次我们对话Galaxy EOS VC Fund资助的公司Everipedia以来，这个团队已经不断在完成其目标：把现实世界的数据和知识带到区块链。最近Everipedia和美联社合作，为选举相关的报道提供一个可信、透明的预言机。
Everipedia的联合创始人Sam Kazemian、业务发展副总裁David Liebowitz、资深前端开发员Dawson Botsford给我们提供了本次和美联社合作的更多信息。
Q:能和我们说说本次美联社和Everipedia合作项目的背景吗？
Sam：我们的愿景一直是把知识带到链上，比如我们想给用户带来信息量丰富的文章、鼓励他们编辑。但最近，我们也意识到，把初始信息带到区块链上，并以预言机的结构呈现，也很重要，这样，智能合约就可以利用这些信息。
我们想扩展链上知识的概念，保证稳定币喂价外的预言机能够在链上购买。其中包括选举结果、新闻头条、通过的法律、或投注赔率。
当我们向美联社提出这个愿景的时候，他们表示非常感兴趣，因为他们是选举报道的黄金标准。过去150年来，他们一直在报道美国大选，同时所有主要新闻媒体和电视有线网络都利用美联社的选举数据作为数据来源。
所以，这极好地展示了我们第一个已被证明的预言机产品，我们也很激动能和他们合作。
Q: Everipedia利用EOS公网在做这个项目，现在项目情况怎么样呢？
Sam:美联社数据库会被部署在EOS公网和以太坊上，EOS应用还有本地EOSIO用例，能够将加密签署的信息发到EOS主网上。
我们在以太坊上利用了Chainlink，因为在以太坊上很难开发，而且如果要构建我们自己的工具实现这些智能合约也是比较消耗资源的。
在EOS方面，我们实际上是在构建我们自己的工具并利用Everipedia自己的基础架构，利用EOS最好的地方是这些预言机可以几乎实时响应，而不是慢慢来。
Dawson：我们在做的是美联社的一个受验证的账户。我可以说，这是世界上第一个这样的产品。美联社会获得自己的公共地址。
我们提供的服务是这样的：美联社会用他们域名中公开的地址的一个私钥签署他们的选举通知。它们不是区块链工程师，所以才需要合作。我们会让他们用自己传统的HTTP API提取选举结果，把信息放在智能合约中，然后告诉世界如何获得放在支持的区块链上的信息。
Q:为什么EOSIO非常适合这个项目呢？
Sam:预言机的一个要素是刷新速度受区块链本身的实际刷新速度限制。所以如果一个区块时间是10分钟，就没有什么能够在10分钟内更新。而EOS只需要0.5秒的区块时间，所以它非常方便。
比如，如果你想获得实时选举地图，在CNN上它会有不同的颜色，这样的实时更新在EOS链上是可以完成的，因为0.5秒区块时间可以支持这个刷新速度。EOS不单单使之可行，还可以让它流利地进行。用以太坊就会有点慢，因为以太坊的区块时间是15-20秒，你可以肉眼看到刷新速度。
我必须提到，EOSIO比起以太坊有一些优点，但是以太坊也有自己的优点。它们特别擅长某个用例，很多东西是专门为这些用例准备的，但是我觉得，对于我们在Everipedia构建的东西来说，EOSIO真的是做得比以太坊更好。
将初始信息和加密签署得信息带到链上需要高刷新速度；其中涉及很多状态变化，但是属性变化却不多。我觉得，EOSIO这方面能力很厉害，因此确实可以做到。
成本也是一个主要原因。从EOSIO上的资源分配角度来说，所有得高投入活动，包括改变去中心化应用状态，都更好，也更容易支付。
我觉得以太坊适合大量属性变化的时候使用。但是，所有产生大量活动的应用都用的是EOSIO区块链。对于我们这个目标而言，我们在做美联社验证的交易时，实际上我们没有改变经济属性。我们实际上就是在改变状态，这些事情确实、毋庸置疑的，在EOSIO上更好。
Q:你觉得这个项目会怎么改变验证新闻的未来呢？
Sam：我个人是希望这个项目代表着打击虚假信息和新闻的第一步。很明显，有了这些具体的选举结果以后，这个项目就不单单是一个展示而已。但是选举以后，不管是从我们现在和美联社，还是和新的伙伴的关系上来说，我们在讨论的一个事情就是我们要如何构造基础架构，加大虚假新闻的传播难度、增加传播成本。
David:我们现在有一些想法，关于我们要怎么增强未来和美联社的合作的想法，不单单是涉及总统选举的问题，毕竟选举四年才一次，还包括日常的新闻内容的。美联社也是体育和体育新闻的巨头，所以我们认为我们和它的关系也是一个不断发展的关系。
我们现在在为马上开始的选举报道制定标准，这不单单是给美联社设置高标准，也是在给未来很多追寻美联社、利用创新应用科技的组织设置标准。
我认为，我们和美联社的合作是和受验证的发行机构的合作。它在数字和真实世界出版发行中间构建了桥梁，也弥补了数字验证的不足。这是一个完美的中间地带，它把两个世界带到了一起。

原文/Original：
Since we last met with Galaxy EOS VC Fund company Everipedia, the team has continued to pursue its mission of bringing real-world data and knowledge to the blockchain. Most recently Everipedia is partnering with the Associated Press (AP) to provide a trusted and transparent oracle for election coverage.
Providing additional insight on the AP collaboration are Everipedia’s Co-founder Sam Kazemian, VP of Business Development David Liebowitz, and Senior Front-End Developer Dawson Botsford.
Q: Can you give us some background on this joint project between the AP and Everipedia?
Sam: Our vision has always been to bring knowledge on chain, such as bringing people informative articles and incentivizing editing. But recently, we realized the importance of bringing origin source information to the blockchain in the structure of oracles so that smart contracts can use them.
We wanted to expand the concept of on chain knowledge to ensure that oracles outside of price feeds for stablecoins can be brought on chain. This includes election results, news headlines, legislation passed, or sports scores.
When we pitched this vision to the Associated Press, they were quite interested because they’re the gold standard in election reporting. They’ve been reporting US elections for the past 150 years, and all the major news sites and TV cable networks use the AP’s election data as their source.
So this was an incredibly cool demonstration of our first verified oracle product, and we were really excited to be working with them.
Q: How is Everipedia using the EOS public network for this project with the AP?
Sam: The AP dataset will be deployed to the EOS public network, as well as Ethereum, and the EOS implementation has native EOSIO usage for pushing the cryptographically signed information to the EOS public network.
We’re using Chainlink for the Ethereum version because it’s difficult to develop on Ethereum, and building our own tooling for those smart contracts is fairly resource intensive.
For EOS, we’re actually building our own tooling and using Everipedia’s own infrastructure, and the great thing about using EOS is that these oracles can be responsive in almost real-time instead of having to be slow and incremental.
Dawson: So what we have working is a verified account from the AP. A world first, I believe. The AP will have a public address in their possession.
We provide a service where the AP will sign their election calls with the private key of the address they publicly display on their domains. They’re not blockchain engineers, so that’s where this partnership comes in. We will allow them to take their election results from their traditional HTTP API and put that information on a smart contract and then tell the world how they can access that information on the supported blockchains.
Q: What made EOSIO a good fit for this project?
Sam: The main thing with oracles is that the rate of refresh is limited by the actual rate of refresh of the chain itself. So if a block time is 10 minutes, nothing can be updated quicker than 10 minutes. On EOS, with half second block times, it’s actually quite convenient.
For example, if you were to have a live election map that turns different colors that you might view on CNN, those live updates can be done on chain on EOS because half second blocks for a rate of refresh is totally possible. And not only is it possible, but it works smoothly. On Ethereum, it’s a little bit slow since Ethereum block times are between 15 to 20 seconds and you can visibly tell the rate of refresh.
I should note that EOSIO does have some advantages over Ethereum, and Ethereum also has some advantages over EOSIO. A lot of these things are specialized for a particular kind of use case that they really excel at, but I think for the stuff that we’ve been building at Everipedia, EOSIO genuinely does excel at what we’re doing over Ethereum.
Bringing information on chain that is origin-sourced and cryptographically signed requires a high rate of refresh; it involves many state changes that don’t have a lot of value changes. I think that capability is fantastic on EOSIO, and it’s been a treat to actually do that.
Cost is also a major factor. All types of high-input activity, including changing the state of decentralized applications, are much better and much easier to pay for in terms of resource allocation on EOSIO.
I think Ethereum is well-suited for moving large amounts of value. But all applications that generate a large amount of activity use EOSIO chains. For our specific purposes, we’re not actually moving economic value when we do those AP verify transactions. We’re actually changing state, and those kinds of things definitely are without a doubt better on EOSIO.
Q: How do you see this project changing the future of verified news?
Sam: My personal hope is that this represents the first step towards fighting misinformation and fake news. Obviously, with these specific election results, it’s more of a demonstration. But after the election, both in terms of our ongoing relationship with AP and new partners, one of the things we’ve been talking about is how do we build the infrastructure so that spreading fake news is more difficult and more costly for people who propagate it.
David: We have a few ideas in the pipeline on how we can extend working with AP in the future, not just with presidential elections because that happens once every four years, but also with common news content. The AP is big into sports and sports reporting as well, so we see an evolving, continuing relationship with AP.
By setting the standard with the election coming up, that sets a high bar for not just AP, but also for a lot of organizations to follow the AP’s innovative use of technology.
I like to think of our work with the AP as a collaboration with a verified publisher. It bridges the gap between digital and physical publications and on chain verifications. This is a perfect middle ground, bringing the two worlds together.
