盗火7期实录：网录科技创始人吕旭军:Uniting World&

活动时间：2018年3月23日21:00-23:00 

活动简介：

源于数字加密货币在公众中的广泛流行，其背后的区块链技术也逐渐得到了公众广泛关注与主流机构的研究。当下区块链行业发展方兴未艾，各种技术发展迅速。现有区块链技术在单链架构下存在性能、容量、隐私、隔离性、扩展上的瓶颈，支持公链、联盟链多链跨链兼容和互操作的跨链技术由此诞生，如果把现有的公链，联盟链比喻为局域网，那么跨链技术将会是打通这些局域网连接的“连接器”，把区块链带入区块链互联网时代。

想象一个理财应用，用户可以用某项资产交换不同机构的理财产品，不同的资产就需要在多条链上做转移、交换。还有一些ORACLE应用同样需要多链间的跨链喂入交互，譬如汇率牌价、天气、股价、特定指标等等。

因此，我们在广泛讨论各种商业场景+区块链时，某些应用在单个公链或者联盟链生态上无法完整实现，如果是基于跨链技术，在多链互联互通，可扩展性、隔离性、高性能、互操作等特性的帮助下，很多想象空间十分巨大的场景都将得以真正实现。

网录科技作为一家专业区块链技术企业，2017年孵化了跨链的基础底层项目——万维链，从未来的应用场景角度来看，万维链不仅是一个实现跨链交易和多资产互通的区块链项目，更是一个开源的区块链开发基础底层，在实现跨链交易功能的同时，也支持开发者基于万维链开发“商业场景+区块链”项目，本期我们邀请了万维链的创始人吕旭军及总裁Dustin Byington从什么是跨链技术，基于跨链的将有哪些可想象的未来应用领域进行分享。

（《如何把世界的区块链联系起来》）

一、My Journey

大家好，我是吕旭军，是北京网录科技的创始人和CEO。今天给大家分享的题目是《如何把世界的区块链联系起来》，非常高兴能够在盗火者联盟社群里给大家分享，实际上我也是这个联盟的发起人之一。

我先介绍一下我的背景，我之前是学企业管理，后来在美国学的是经济学，再后来就进入计算机行业。已有20多年，主要是在美国的中西部和德克萨斯州，做了很多年关于计算机和商业应用。在12年的时候接触到了比特币，也做了一些投资。最开始的时候，参加了一个小范围内的基金，当时是一个分布式基金，这只基金主要投资全球的区块链的项目。

在那个时候，基金回报是非常的好。项目没有像现在这么多，但是，我们接触到的都是一些全球的团队，项目都非常的好。当然，在那个时候也有一些泡沫，实际上，在2013年的时候，这个泡沫也是破掉的，当时，整个币圈，跌的是一地鸡毛，很多人是也是受伤惨重！

但是，好的项目终究是会存留下来的，在那个时候，我们就参与了一些基础性的研究。有幸的接触到这个行业里的一些精英分子，一起研究的前沿话题，探讨怎么把区块链的应用能够落地，以及在这个行业里面做一些探索。事实上今天跟我们一起分享的Dustin就是在那时候认识的。

在2014年的时候，我跟几个朋友在奥斯丁发起了一个项目叫“Factom”，中文名字叫“公正通”。当时是为了解决比特币的区块size太小了的问题，当然，到目前为止，这还是一个比较大的争议的题。当时我们提出来的一个方法，就是把一些数据能够再移到另外一条链上，实际上是比特币的链下，用“公正通”来解决这个问题。

当时“公正通”目的是在区块链建立数据层，因而得到广泛的认可，在全球的区块链项目里面，排到了前十，而且排了很长的时间，特别是让著名的期刊-经济学人在2015年10月的期刊上深度报道。从此，区块链从一个极客玩的东西正是走入了主流媒体的殿堂，我们也因此全球知名。事实上，我们的一些设计被很多的团队采用。所以，我认为在整个投资行业，或者说价格低迷的时候，只有那些坚持做事业，坚持把事情做成，长期坚持的这些团队，才能够把事情真正地做成。

二、Back to China

我负责“公正通”在中国的一些业务。实际上，我跟中国的整个圈子，在14年的时候就有很深的一些联系了。在15年的时候，国内各个城市巡回，跟各个地方进行接触的时候，发现国内市场可能跟我原来想的不太一样，特别是在我们推广企业级的应用的时候。我们把区块链的技术，推广给政府、金融企业时，发现在当时“去IOE”的政策的指导下，我们在国内的应用推广，还是比较困难的。

所以，当时也是接受到了北京招商局，杭州的长三院，以及一些朋友的邀请。最后，我决定在16年的时候回国创建一个公司，叫网录科技，也是延用谷歌和百度的思维方法，即先在中国内部建一个本土化的区块链的公司，然后再把这家公司带向国际。

三、Two Parallel Lines of Blockchain

在国内推广的过程中，我们也发现，有些事容易推广，有些事比较难的。我先讲难的，在推广的过程中，特别是跟传统的金融行业推广的时候，发现这个阻力是相当大的。因为，区块链是一个全新的技术，首先需要有一个普及，让他们去接受这个技术，然后，我们做POC让他们来看，最后转化成真正上线的产品，这个距离是相当长的。

当然，各个金融行业，也包括其他的一些供应商在这方面不遗余力地推，也来自于整个金融行业开始意识到区块链技术的重要性，不断的在这方面做各种各样的实验和尝试。但是，总体来讲，这个方面还是相对来要慢一些。现在，我们看到很多国内大的企业都开始做区块链的项目，但总体来讲，区块链在实际上应用的速度和收效都没有比我们原来想的那么快，那么大。

在另外一方面，从原来的虚拟货币和一些新兴的虚拟货币，能够跟数字经济或者说跟数字经济跟相近的这些地方连起来的时候，我们讲的数字货币也好，token也好，“通证经济”也好，在这个行业里面，我们发现速度是非常快的。包括国外对国内的这些影响，也包括2017年整个行业进入一个疯狂的状态，就像我在12、13年见到的状况非常相似，而且这个泡沫是比原来还大很多。

所以，我想这是两个平行的世界，区块链的应用是不断的在发展，但我们一直觉得这两个行业早晚会胶合在一起。只是就目前来讲，一个速度更快一些，一个速度更慢。那么如何能够把传统的金融行业与新兴的数字经济结合在一起？这是我们一直在的思考问题。

四、Infrastructure for the new token

然后，我们找到一种解决方案，我们提议为未来数字经济里的基础设施。我们创建了“Wanchain”，这个项目是取自于网录的头三个字母。“Wan”的意思是把原来的相对独立的经济体，最后连成一个广域网，把大家都连起来。我们看到上面这张图，我们把“Wanchain”放在中间，最上面都是一些公有链，比如说以太坊、比特币，下面的是私有链，还有，我们讲的联盟链，大家都可以互相的打通。特别是，在传统的经济或者其他的一些政府、企业级的解决方案里面有很多联盟链，通过我们跨链的技术，能够把单独的系统跟整个数字经济都连起来。

五、Wanchain Technologies�

我们万维链有三个比较核心的技术，即隐私保护、跨链和智能合约。我单个来讲，比如说，隐私保护在联盟链里面是非常重要的，任何几方在做生意的时候，他的交易是不希望其他人能看见。隐私保护有很多种解决方案，我们采用的是“一次性地址”和“环签名”的方式。通过这种方式，能够把一定的信息隐藏掉，那么目前来讲，我们觉得这是最好的一个方案。但是对我们的方案，我们也进行了一些改进。

跨链，是我们经过了很长时间的研究。最后受到一位华人科学家启发，清华教授姚期智老师。姚老师最开始提出了一个百万富翁问题，从而引申出来的安全多方计算和门限密钥共享的技术。通过这个技术，我们不需要对原链进行任何的改变就能够成功的把另外一条链连起来。

对于智能合约，我们基本上是能够兼容以太坊上开发的各种智能合约，基本上能够无缝的挪到万维链上面来，这是非常重要的。我觉得目前综合各个开发社区，以太坊的社区是相当大的。到目前，全球有几万开发人员在上面建立各种生态。当然了，假如说能够加上隐私保护，再加上一些针对万维链的一些特定的合约的模块，那这个功能实际上是更完备的。

这三个技术，看起来都不是那么光鲜亮丽，但是我们把三个技术连起来，它的意义就非常的巨大。因为原来的一些智能合约是在一条链上，里面的资产是有限的。当我们把更多的链打通，然后加上带有隐私保护的的智能合约，我们确实能够实现真正的多链条全数字生态的新经济，而且我们能够让它可编程化，所以，能够用来这个作为未来数字经济的基础设施。

六、Wanchain Ecosystem

当然，我们万维链的远景不只是建立一条链，我们的远景是要建立一个新的基础设施，在这个基础设施上，有一个完整的生态。那我们目标是做什么事情呢？事实上就是要把资本跟资产连起来。如上图所示，右边是资产，就是各种各样的数字资产，包括在比特币或者以太坊上发行的资产，也包括联盟链上新增出来的跟现实世界锚定的数字资产。这张图的左边是我们所说的资本，资本可以是来自于机构和个人，包含法币和数字货币。形式也是多种多样的，可以是基金的形式，或者是token的形式，还可以是传统的Equities的形式，都能够进入到这个生态里面来。在这个生态里面，我们有第三方的一些应用，就像我们是一个开放的安卓系统一样，在这个系统里面，第三方可以在上面开发各种应用。我们也跟第三方的一些机构进行合作，比如像媒体、数据方进行合作。我们给上面的这些应用，包括分布式的应用，提供各种各样的工具和数据。

当然了，因为我们万维链自动带有一个联盟链的方式，能够把这个生态建得更好！待会，我们还有一些具体的想法跟大家讲，如怎么把万维链和联盟链连起来，能够再继续丰富整个生态。

那么下面有请Dustin讲下，我们对万维链的一些新的看法和应用案例。

七、Cross-Chain Technologies & Applications

Well everybody my name is Dustin Byington. I'm the president of Wanchain. I started my career at Goldman Sachs that was in 2007， one year before the financial collapsed， and that really shaped my thoughts about the larger financial services industry. Soon after leaving Goldman，I started on my entrepreneur journey and found bitcoin in 2013. When I found a bitcoin，I saw at the promise to fix some of the fundamental and systemic problems that I saw firsthand working at Goldman Sachs， and began starting companies in space.

Some of the first company I started was a firm called Satoshi Talent. It was the first block chain recruiting firm. Idea was that I didn't know which direction the industry was going to go in but be an entrepreneur and knew the value of services businesses and the value of selling what I thought of as， pickaxe and shovels，and so I am starting this recruiting firmallowed me to meet Jack Lu affect them and many other entrepreneurs in thespace including Jake Wan of Tendermint. Soon thereafter I became a cofounderand president of Tendermint and worked with him for some years soon thereafter Istarted Stokens Venture Capital.

When Jack Lu gave me a phone call one afternoon and told me about the new project that he was working on. I immediately picked it up，because Jack has a great respect in the local Austin block chain community being the technical co founder of Factcom， and someone who had worked closely with on a number of different fronts. Then when I found the grand vision and some of the larger stomach problems in the block chain industry and its potential impacts in the wider financial services industry，I immediately jumped on board.

Not only does Wanchain have the potential to solve some of the very significant problems within the block chain industry，but also in solving those problemscan potentially solve some of the larger problems in the financial services industry.Our vision is that instead of trying to repair the larger industry we're actuallygoing to rebuild it from the ground up.

Jack earlier alluded to the power of this platform and all it's capable of. One of the things that being in the industry for some time and seeing many platforms come and go that I have realized and come to know quite firmly is that platforms. The idea that if you build a platform， and other think that other people will just simply build applications on top of it that's simply not true. It's really important that we take it upon ourselves to build these quality applications，because the value of our platform will be judged by the quality andquantity of applications built on top of it.

And that's why we're really excited to announce WANLabwhich is the digital asset factory. One of the things that we've come to realizeis that building block chains is really hard. There are really not too manyteams that have successfully built block chains and watching enabledapplications before. We have some very unique experience that we can share withthe applications are that are leveraged on our platform.

These challenges stem from everything such as which applications should utilize block chain technology. Oftentimes it's very easy to get down very long rabbit holes， and then realize that in fact， you don't need a block chain at all， or to think about how to leverage block chains creatively and efficiently. There are a number of legal and regulatory challenges that make it very easy for projects to make mistakes early on that they can't recover from. Both Jack and I have seen these errors many times and in fact，sometimes we've even made someof the mistakes and learn from them ourselves and we don't want our applicationsto have to go through that.

Other challenges include simply things like a recruitment. The level of number of qualified developers and the spaces is very low. Finding the right legal team，the right branding designers， agencies， folks to help you construct and develop your white paper， these are all challenges that we find come over and over from our applications. So there are some inefficiencies of us，helping those projects because these are oftentimes repeat problems. 

One of the biggest things that we're looking for when sort of front of this lab and digital asset factory are exceptional teams with grand visions. That's the thing that is really unique and really hard to replicate and replace. As we're out there scouting for projects， our first filter is team we believe in that has a lot of passion and is going somewhere that's a vision. It's big enough that we want to， beyond the journey with them. So if you know any teams that sort of live up to the standard please have them reach out to us，we'd love to have a talk with them.

Once we've identified these teams， one of the power of our platform then begins to shine. It is a lot of problems，that werepreviously thought to be unsolvable or for whom the solutions were incrediblycomplicated becomes very simple and easy to solve with the power of ourunderlying technology.

We often start with projects that are at very early stage. That are still thinking about their idea. They have a rough draft of a white paper or a great team in a big vision and then take them through the full life cycle and all the way out through developing. I see finding the right marketing and legal team，then going through the end， helping them with marketing and building out the rest of their team. Ultimately all these efforts are result of hoping that the platform because we realize that our platform will be judged by the quality and quantity of applications that are built on top of it.

An example of one of our first projects is smart bomb platform. They were drawn to Wanchain because on a theorem they are limited to the sort of the galaxy of USE 20 tokens. With Wanchain， they get access to all of the protocol tokens which really increases the scope of the problem that they are able to solve. And this is true for a number of applications that otherwise would be really limited in the scope of their solution.

The same group has created a compliance layer that enables us to bake regulation directly into the token itself. This is something that we're really excited about because that means that tokens can be smart. And the token itself can enable not allow itself to be transferred to somebody who isn't accredited or hasn't gone through a specific KYC and a process that means that Wanchain will be able to offer regulated security tokens much sooner than we were anticipating.

We are also building a wallet specifically for asset managers that solves some of their unique problems and allows them to do things like automatically pay out to some of their LPS， and also solve some of their security concerns，which are not able to be solved using other technologies.

When you think about Wanchain infrastructure， we are building few infrastructures for the future of finance. On top of Wanchain， you can build wide variety of applications and services， including the aforementioned lending platform， the asset management tools， will also be working on exchanges， index coins， index tokens and a wide variety of financial tools that we think will really reshape imagine and rebuild the financial services industry.

We get a lot of questions about scale. It's， actually the wrong question. Because when people ask us about scale， what they are really asking us about things like how many transactions per second can your block chain enable. As mentioned earlier I was formerly a co-founder of Tendermint and one of the things I learned at first hand was that consensus algorithms are commodities. Nobody wants to pay to build on something that is closed source， that is because if they do then over time you can increase the fees，and they are stuck because they've already built theirinfrastructure on top of it. So what this means is that over time can sensealgorithms will need to be public and open source.

If consensus algorithms are public and open source that means they live on get hub and we， at Wanchain will be able to leverage them. There are lots of different technology providers that are working on a wide range of scaling solutions，we have a fairly large team at the fortuneof meeting some of these folks here this week as visiting the Beijing office ofresearchers from on our team and from Peking university that are looking atthese various technologies and soon they'll be deployed in the wild and we'llbe able to see which ones are really successful and how effective they are.

We evaluate these after Wanchain 2.0 will really begin implementing some of our quote， unquote scaling solutions. And there's a large number of them and some of them are starting to look promising， it's still very early in the block chain scaling days. But we are confident that if it's not a theorem camp and Caspar plasma and the number of scaling solutions they have， there will be other teams that develops killing solutions，that will be able to implement.

That means that we can focus our efforts on two mainareas. One is on the technology side where Jack Lu talked earlier about ourunique contributions of space with the cross chain technology. And two we canfocus on scaling the part of the ecosystem that I think is going to really bethe differentiator which is the applications that are built on top of ourplatform.

It is this scale that creates the real networkeffects. This scale career is going to create the real winners or losers in theindustry. You can think about the difference between a blueprint to New Yorkcity and the entire collection of buildings and people and cars. It's one thing.It's very easy to you know to be able to cut and copy a blueprint. But it'svery challenging and impossible to be able to cut and copy the network ofpeople and buildings and cars. So what we're doing is we're building thatnetwork. We're building that scale of solutions and applications serviceproviders and we're doing it with vigor and we're doing it with a lot ofintent.

That's what the WANLab is all about. The WANLab is providing that ecosystem scale and we will be announcing some more specifics about our first six applications and block chains， at the Dubai conference，on April 16th， you can find more information at DIBS. 

（进入主持人提问环节）

问题1：目前项目进展到什么阶段？万维链打算如何建设你们的生态？

吕旭军：这个“万维链”项目经过一年多的开发，在今年的年初1月18号，在主网上线。我们刚才讲的三个核心技术，目前已经完成了两个，一个是隐私保护，另一个是智能合约，完全是可用的，现在各个项目的正在上面进行应用开发。除了这一点，我们下一阶段开发，就是在我们万维链2.0要实现跨链。第一步，我们希望实现与以太坊的跨链，第二步的话就是万维链3.0，实现与比特币的跨链，希望是今年年底之前，能够把这个都做出来，然后再下一步实现与联盟链的跨链。

吕旭军：刚才Dustin也讲了怎么在我们万维链上建设生态。我们基本的想法，是建设一个开放的社区，像安卓系统一样，各方的都能够在上面开发应用。但是为了使生态建设更容易，让更多的人来，我们采取了一些积极的措施，第一步是建立我们自己的基金，第二步也建立了自己的实验室，然后跟第三方，就是产业链的各个合作方一起进行合作，共同建立这个生态。

问题2：现有在在做跨链的公链有哪些？分别的代码技术如何？

吕旭军：事实上，跨越这个主题已经进行了好多年了。实际上，这是在行业里面非常难以解决的问题。当然，现在有好几个项目跟我们一样，同时的攻克这样的一个问题。在全球范围内有几个比较强大的团队，像AION， ICON跟我们一块去寻找解决方案。待会我也会跟大家讲一下，我们建立的跨链联盟。通过这个联盟去共同协作最后就是希望能够建像TCPIP的全球标准。

吕旭军：从代码程度来看各个项目还都是在处于初级的阶段，每个项目的采用的方法都不一样，都有一些独特的地方，目前还看不出来，哪个项目好，哪个项目不好。但是我觉得，在今后的一段时间内，我们会共同协作找出一个最好的方法。因为我们是一个完全开源的社区，最后做出来这个东西，假如说能够作为一个新标准的话，大家共同采用是最好的，当然这也是一个过程。我们最开始的第一步，需要先把自己的链建起来，然后再跟其他的链连起来，这是我们目前计划的一个步骤。

问题3：看到说万维链与AION、ICON三方联合宣布共同成立区块链跨链联盟（Blockchain Interoperability Alliance），将在区块链跨链技术领域研究及国际相关标准的制定上展开协作。这对万维链有什么意义？联盟成员之间是怎么合作的？ For Dustin please.

Dustin Byington: One of the things，AION， ICON and Wanchain realized was that we were seeking to solve a very similar problem， that gives the state of the industry. We were very much likely to solve it if we work together， and that the industry was still so small that it was better to focus on growing the industry and increasing our chances of solving the problem，than fighting over market share.

Dustin Byington: This was the original formation of the alliance. Just this realization that we were all heading in a similar direction and we might be able to help each other. We were also aware that we are coming at the problem from different perspectives， it would be important for us to be able to communicate with one another. That interoperability was likely not a winner takes all scenario and it would be good for all of the various interoperability chains to be able to connect and communicate，so that we could create a morecomplete solution.

Dustin Byington: Since that those initial， this took place in New York end of last year and since then， the three teams have maintained stayed in contact，we looked forward to，we actually Jack and by our team invited them out to China，they'll be attending conferences with us at in both Beijing and inHangzhou. There will be starting to talk a little bit more specifically abouthow we can coordinate and work together. The first thing is to make sure that ourchains can communicate and that two degree on some road maps moving forward. Nowthat all of our main nets are up we have a little bit more time to startfocusing on coordination and communication together.

问题4：我们都在探讨商业场景+区块链，把传统资产上链，你认为什么样的资产适合上链？万维链会不会协助这些资产的上链，如果是，你们会优选哪些方面的资产呢？

吕旭军：把资产上链是一个相对难的或者说一个有挑战性的问题。事实上，现实世界里任何的资产，包括物理的资产，只要能够建立起一对一的关系，都能够在区块链里面完成资产的锚定。那么，在区块链里这个资产就可以切分，可以交易。但是，因为现实世界里面的资产跟区块链中间的过程，目前来讲需要有一个中心化的机构进行认证，或者多方进行认证。所以目前来讲，这还是行业里面一个比较难以解决的痛点。当然了，假如说，本来就已经数字化的资产可能就更容易了.比如说像信息行业，内容分发行业，能够把知识转化为资产，就是我们讲的知识资产，这个是更容易这个上链的。

问题5：万维链有没有帮助传统资产上链的案例？有的话，方便简单介绍一下是什么类型的项目， 万维链是如何帮助这些项目资产上链的吗？

Dustin Byington: I am happy to give you a little sleep wreak peak of some of the projects we were working on. There's one that's a group out of Dubai that's a group of investment bankers who have done more than thirty billion dollars’worth of transactions in their career and one of the things that they wanted to do was to create a stable coin for Africa that could help solve some of their financial inclusion problems. This was a really good example of a project working through WANLab because while they came with this original idea and vision，they broughtall these relationships to the table there was a lot to be fleshed out with theactual execution of the idea.

Dustin Byington: After many rounds of iteration， what we've ended up with is a really phenomenal stable coin that solves two of the unknown quote black swan threats of traditional stable coins. Traditionally the two ways to create a stable coin. One is that you do something like maker dow which is create a contract for difference， whereby you effectively aremaking that's based upon underlying collateral. The problem is with the problem with maker dow is that， the underlying collateral they use is ether，and if ether moves more than thirtypercent in a day then the stable coin has the potential of breaking. The other way to going about a stable coin is to take a bunch of currency like US dollars， and stick them in a bank account， and then create IOU for that collateral， and the problem with this the quote unquote black swan with this is that. If that bank account gets closed either by the jurisdictional reach of the United States or some other means，then again that's table coin can break.

Dustin Byington: what we are going to do is to combine the two models.We'll use something that looks quite similar to maker and their contract for difference model， but instead of using east as a collateral we will use physical commodities，and have ourrelationships with a really tremendous. Warehouse and commodity providers thatthe group were working with brings the table to take this vision and turn itinto a reality.

Dustin Byington: There are a number of other projects， three of them I had the pleasure of meeting in person today that are coming out of China that are focused on media， travel and gaming. Each project again brings a really tremendous， exceptional relationships and to the table. In this case and in the form of millions of users who currently use their projects，now can be users of our decentralized applications and blockchains.

吕旭军：今天非常高兴能够跟大家分享，实际上我们明天还有一个活动，在北京维持酒店举办北京区块链峰会，具体讨论一些区块链在商业场景里的应用落地和我们下一步要做的计划。欢迎大家参加。同时本月26号在杭州，我们有一个全球区块链峰会。刚才Dustin也讲了，主要是把跨链相关的行业里面的领袖请到杭州，一起探我们下一步要做的跨链的标准协议路线图，和我们下一步的计划。

Dustin Byington: Thank you all for joining us tonight. We will be continuing to be travelling around the world and living on planes and sleeping at our desks to make this vision a reality. We have the upcoming meet ups in Beijing， Hangzhou， Shanghai. Soon thereafter will be in Lendit San Francisco Conference，will then be going to Tokyo. We have Tokyo，Dubai，and Toronto are on the near term schedule. If you keep follow us on twitter or Telegram groups， those are the best place to get to the up-to-date minutes or schedule will continue to post，or upcoming locations if you'd like to join us at any of thoseevents. Again thank you for joining us tonight.

主持人李尼：感谢大家今晚的宝贵时间！希望有更多好的落地场景和项目和网录一起推动区块链技术的发展和落地！
