七彩研究院雪糕：各位小伙伴们下午好，我是今天直播间的主持人，感谢七彩研究院的各位小伙伴们能够准时和我们相约，今天我们很荣幸邀请Paralink CEO：Jan Knezevic&CMO：Andrej P.Skraba到做客七彩研究院，开展一场以“深度对话 Paralink Network:Web3.0世界的预言机形态”为主题的直播活动！本次AMA采取中英文对照模式,让我们进入今天的AMA主题活动。

 Q1、Caroline：Welcome Paralink CEO Jan Knezevic and CMO Andrej P. Skraba. Could you please introduce yourself to everyone briefly?

Q1、七彩研究院主持人雪糕:欢迎Paralink的CEO Jan Knezevic与 CMO Andrej P. Skraba ，请两位向大家简要介绍一下自己吧！

CEO A1: I am Jan Knezevic and im the CEO of Paralink Network. My background is in business and economics- more specifically i worked as an auditor, i was an actuary in a life insurance company and later on i transitioned into consulting blockchain projects with accounting and business development as well as conducting internal audits. Last year i was part of a team that acted like a data vendor for blockchain data, we collected pricing, on chain and sentiment data and created qualitative indicators for traders. I was also an active day and swing trader on the stock market trading stocks and stock options and later on transitioned into trading cryptocurrencies. 

CEO A1:我是Jan Knezevic，Paralink Network的CEO。我的主要从业背景为商业和经济学——更具体地说，我曾在KPMG做过审计师，在一家人寿保险公司做过精算师，后来我转入区块链项目咨询，涉及会计和业务发展，以及进行内部审计。去年，我作为区块链数据供应商团队的一员，我们收集价格、链上和情绪数据，并为交易员创建定性指标。我也是一个活跃的交易员，在股票市场上交易股票和股票期权，后来转为交易加密货币。

CMO A1: Hi, I’m Andrej P. Skraba, and I’m a CMO at Paralink Network. Before joining Paralink, I worked at NiceHash, where I held the position of a CMO and helped the company transition to a global brand in the cryptocurrency mining industry. Before that, I worked as a Head of Marketing at EK Water Blocks, a world leader in custom liquid cooling solutions for the computer industry. With more than a decade of experience in the high-tech industry, I want to leave my mark in the cryptocurrency industry.

 CMO A1:大家好，我是Andrej P. Skraba，我是Paralink Network的首席营销官。在加入Paralink之前，我曾在NiceHash担任CMO，并帮助该公司转型为加密货币挖矿行业的全球品牌。在此之前，我曾担任EK Water Blocks的营销主管，该公司是计算机行业定制液冷解决方案的全球领导者。我在高科技行业有超过十年的工作经验，今后我希望在加密货币行业也留下自己的印记。

Q2：Caroline：Could you introduce Paralink Network to our new friends here? 

Q2、七彩研究院主持人雪糕:向大家介绍一下Paralink Network吧？

A2：Paralink is a multi chain oracle platform and we decided to build it on Polkadot.

First of all, the real-world data ingress is done by Paralink Nodes through our own Paralink Query Langauge-PQL. This allows one to query SQL databases, access web APIs, scrape websites as well as access state from other blockchains. Its a robust solution which is easily expandable to support custom data sources (actually right there is an issue with the existing solutions since the technical barrier to create a custom data source is high and takes forever). Besides the data, we have support for post-processing in a permissionless way via on-chain relayer quorums as well as reliable channeling of the computation results via PQL callbacks. 

The next aspect of the project is the Paralink node and its query language. WIth it, you are be able to query APIs. databases but also parse JSON, XML and HTML, support multiple data sources, apply math functions, do type casting, aggregations and much more.

The last point which is extremely important to us is the On-chain security as well as the integrity of this data. This is a huge challenge and we think that so far it hasn’t been solved properly. So in Paralink, we have something called Relayer quorums which are self-organizing data repositories with reward token mechanics (as well as slashing of course) that aggregate and validate real-world information. Our infrastructure is built with Substrate which means we get high throughput and economically feasible computing costs. Due to this technology stack, we can also relay computation results from Polkadot to other chains as well, but also monitor reliability via public reputation systems.

A2：Paralink是一个设计在Polkadot波卡网络上的多链预言机平台。

首先，真实世界的数据输入是由Paralink节点通过我们自己的Paralink查询Langauge-PQL完成的。这允许查询SQL数据库，访问Web API，抓取网站以及从其他区块链访问状态。 它是一个强大的解决方案，可以轻松扩展来支持自定义数据源（实际上，由于创建自定义数据源的技术壁垒高，花费时间久，因此现有解决方案存在问题）。除了数据之外，我们还支持通过链上中继器仲裁以无许可的方式进行后处理，以及通过PQL回调，可靠地传递计算结果。

 Paralink的另外一个特点是他的节点及其查询语言。通过它，用户可以查询API数据库，还可以解析JSON，XML和HTML，并且支持多个数据源，应用数学函数，进行类型转换，聚合等等。

最后一点对我们来说极为重要，那就是链上的安全性以及数据的完整性。这是一个巨大的挑战，我们认为到目前为止还没有得到妥善解决。因此，在Paralink中，我们有一个称为“中继器法定人数”的东西，它是带有奖励令牌机制(以及剔除错误)的自治组织数据存储库，能够聚合并验证真实世界的信息。我们的基础设施是使用Substrate构建的，这意味着我们可以获得高吞吐量和经济上可行的计算成本。由于采用这种技术堆栈，我们还可以将计算结果从Polkadot传递到其他链，也可以通过公共信誉系统监视可靠性。 

Q3、Caroline：What is the overall planning of the development route of Paralink Network? What stage is it in at present？ 

Q3、七彩研究院主持人雪糕:Paralink Network 发展路线整体规划是怎样的，目前处于哪个阶段 (JAN)？

A3: We are very much focused on business development. Paralink is a B2B project and we want to serve other companies and projects that are incorporating smart contracts in their solutions. For that reason, we are developing a new website that will focus on developers and provide a better onboarding experience for them. Our focus is on new partnerships that require data ingress for their smart contracts. Currently, we are still aiming to secure our parachain slot on Polkadot as we want to use XCMP protocol to serve other parachains. But we are also fully compatible with Ethereum and Binance Smart Chain. Polygon support is also in the works and we plan to support Cardano in the future. 

A3:我们非常专注于业务发展。Paralink是一个B2B项目，我们希望为其他将智能合约纳入其解决方案的公司和项目提供服务。出于这个原因，我们正在开发一个新的网站，专注于开发人员，并为他们提供更好的入职体验。我们的重点是拓展需要为智能合约提供数据入口的新伙伴，目前，我们仍然致力于在Polkadot上保护我们的副链位置，因为我们想使用XCMP协议来服务其他的副链。但我们也完全兼容以太坊和币安智能链，并且也支持Polygon，我们计划未来同样支持Cardano。

Q4、Caroline:What other ecosystems does Paralink Network currently serve apart from the DeFi sector as oracle?

Q4、七彩研究院主持人雪糕：作为预言机，除了传统DeFi板块外，Paralink Network目前还在为哪些生态服务？(Jan) 

A4：Currently, there is not much demand for oracle services outside the DeFi sector. Price feeds are the most popular form of data requests that oracles serve at the moment. Due to the nascent nature of smart contracts, we are yet to see the wide adoption of oracles outside of DeFi. This space is still very early and holds immense potential for growth in the coming years.  

A4:目前，在DeFi领域之外，对预言机服务的需求并不大。价格反馈是目前预言机提供的最流行的数据请求形式。由于智能合约的新生特性，我们还没有看到在DeFi之外的预言机被广泛采用。这一领域仍处于起步阶段，未来几年仍有巨大的增长潜力。

Q5、Caroline:Congratulations on the recent cooperation between Paralink and Polygon. Why did The Paralink Network choose Polygon as partner? What other ecological partners are there now? 

Q5、七彩研究院主持人雪糕:恭喜最近Paralink与Polygon达成合作，请问Paralink Network为何选择Polygon作为合作伙伴，目前的生态合作伙伴还有哪些呢？(Andrej) 

A5：We were very excited to announce integration with Polygon. As you know Polygon is a protocol and a framework for building and connecting Ethereum-compatible blockchain networks. 

By building on secured chains and standalone chains, Polygon is tackling the Ethereum scaling problems. The team behind Polygon aims at creating a framework that makes it possible to aggregate scalable solutions on Ethereum, supporting a multi-chain Ethereum ecosystem.

Paralink Network integration with Polygon enables accurate, decentralized, and reliable data feeds to its chains. By providing secure and dependable multi-chain oracle solutions, Paralink allows users to benefit from its on-chain consensus algorithm, running on Polkadot Substrate, enabling the highest security applications.

All of our partnerships announcements are available on our blog: https://blog.paralink.network/

A5:我们非常高兴地宣布与Polygon集成，众所周知Polygon是一种协议框架，用于构建和连接与以太坊兼容的区块链网络。

通过构建安全链和独立链，Polygon正在解决以太坊的扩展问题。Polygon背后的团队旨在创建一个框架，使其能够在以太坊上聚合可伸缩的解决方案，支持多链以太坊生态系统。

与Polygon的并行网络集成能够为其链提供精确、分散和可靠的数据。通过提供安全可靠的多链预言机解决方案，Paralink允许用户受益于其在Polkadot Substrate上运行的链上共识算法，实现最高安全性的应用程序。

我们所有的合作公告都可以在我们的博客https://blog.paralink.network/上看到

Q6、Caroline:What role does Paralink Network play in Web3.0? 

Q6、七彩研究院主持人雪糕:Paralink Network在Web3.0中扮演什么样的角色？(Andrej)

A6：Web 3.0 is a leap forward to open, trustless and permissionless networks. One of the most important pillars of the next generation web will be decentralized data networks. We believe that oracles will play an important role by bridging the gap between blockchain data (on-chain) and real-world data (off-chain). We want to provide the best possible solution for developers that will require data ingress in applications that require the highest degree of security. Paralink’s on-chain consensus algorithm, running on Polkadot Substrate and Paralink’s flexible node design allows developers to query real-world events, sports, weather, random numbers, and more. 

A6:Web3.0是向开放、不受信和无许可网络的一次飞跃，下一代网络最重要的支柱之一将是去中心化的数据网络。我们相信预言机将在区块链数据(链上)和真实世界数据(链下)之间发挥重要作用。我们希望为需要在最高安全性的应用程序中输入数据的开发人员提供最好的解决方案。在Polkadot Substrate上运行的Paralink链上共识算法和Paralink灵活节点设计，允许开发人员查询真实世界的事件、体育、天气、随机数等。

Q7、Caroline:For a project that sold out on Polkastarter in less than 60 seconds, it is currently available on many major exchanges. What are your next marketing plans in the near future?

Q7、七彩研究院主持人雪糕:作为仅仅60s，便在polkastarter上售罄的项目，目前也登陆很多主流交易所，后期会有更多的市场规划吗？(Andrej)

A7：We are focused on establishing new partnerships so there is a big effort on business development at the moment. We are reaching out to other projects and teams that are developing solutions with smart contracts. Like Jan has mentioned before, we are becoming blockchain agnostic, supporting ethereum (ERC-20), Binance Smart Chain (BEP-20), Polygon, Cardano, etc. Of course, we also have to educate the market, so we are working on content marketing and we will soon deploy a new website that will focus on developers. At the end of the day, we want to provide developers a great product and this is where the value is coming from. 

A7:我们专注于建立新的合作伙伴关系，因此目前在业务发展方面做出了很大的努力。我们正在接触其他正在开发智能合约解决方案的项目和团队。就像Jan之前提到的，我们正在成为区块链不可知论者，支持以太坊(ERC-20)、币安智能链(BEP-20)、Polygon、Cardano等。当然，我们也必须教育市场，所以我们正在致力于内容营销，我们将很快部署一个新的网站，重点关注开发者。最后，我们希望为开发者提供一个伟大的产品，这也是价值的来源。 

Q8、Caroline:What are the current barriers or challenges facing Blockchain oracles, and what can be improved and how Paralink is going to be different

Q8、七彩研究院主持人雪糕:请两位分析一下现阶段的预言机有什么弊端，以及有要改进的地方吗？

A8：The biggest challenge is technology adoption. It is crucial to understand that this space is very early and a lot of projects are looking for a product-market fit. Smart contracts exist only for a few years now and only very early adopters are using it – predominantly DeFi. Once the wider adoption happens we will see a huge increase in demand for blockchain oracles. Once this happens Paralink will have the best possible solution that is open source and highly flexible for any project today and in the future. 

A8:最大的挑战是技术的采用。重要的是要明白，这个领域还处于早期阶段，许多项目都在寻找适合市场的产品。智能合约现在只存在了几年，而且只有非常早期的采用者在使用它——尤其是DeFi。一旦广泛采用，我们将看到区块链预言机的需求将大幅增长，一旦这种情况发生，对于现在和将来的任何项目，Paralink都将拥有最好的开源和高度灵活的解决方案。

七彩研究院主持人雪糕：好的，非常感谢Paralink CEO：Jan Knezevic&CMO：Andrej P.Skraba的精彩分享，为此我们也对Paralink有了全新的认识，接下来关于Paralink有任何疑惑的小伙伴可以在自由提问环节提出你的问题，嘉宾会随机挑选问题进行回复。

Q1:What is the “Relayer quorum” reward system in Paralink?

A1:Relayer quorums are self-organizing groups of Paralink Node operators, who’s job is to service the data requests. Relayer quorums earn fees for providing the service (PARA token) and can be penalized – have their revenue and or stake slashed – via Reputation system.

Q2:When will the new website and product come out?

A2:New website is coming out in a few weeks!

Q3:Now NFT is so hot, have you considered developing towards NFT?

A3:Yes, our Paralink Node can also be used for NFT where data ingress is needed! We plan to work with NFT projects in the future.

Q4:What’s your moat? If others copy the same model, are you confident that you will not be occupied by market share? 

Q4:The hash is only 32 bytes long, which is significantly shorter than the job definition itself, making it suitable for request signalling on resource constrained chains such as Ethereum. This means that using Paralink Node is much cheaper than other solutions on the market so developers dont have high cost using an oracle which is a big problem with other solutions.

Q5:What is the revenue model? What are the benefits for token holders?

A5:To understand our model please read this blog post that explains how data ingress will work and how token will be used for paying data ingress: https://blog.paralink.network/paralink-network-data-ingress-overview/

Q6:What is your global expansion plan? At present, which market does Paralink focus on, or on building and developing to win customers, users and partners?

A6:We are focued on worldwide adoption and want to work with smart contract developers on ethereum, Binance Smart Chain, Polygon, and later also on Cardano and any other smart contract blockchain.

Q7:Which well-known projects has Paralink reached cooperation with? What well-known institutions have been invested?

A7:All projects partnerships are listed on our blog and also our investors.

Q8:What is Paralink’s marketing and large-scale adoption strategy? What message do you want to send to the community through AMA today?

A8:We are fully focuesd on delivering a great product to smart contract developers and we belive PQL will change how developers approach the development of data ingress.

七彩研究院主持人雪糕：由于时间关系，本次AMA即将结束，后续有更多项目信息我们将继续在群内分享。感谢Paralink两位嘉宾为七彩用户带来的精彩演讲今，也非常期待再次做客七彩社区。
