XT exchange's innovative social model empowers the blockchain industry through newly developed social trading avenues, which were once not possible. XT has achieved this through a combined effort with our partners, like Bananatok.
XT交易所社交化创新模式通过新开发的社交交易渠道为区块链行业赋能，这在过去是无法实现的，但是XT通过与Bananatok等合作伙伴的共同努力实现了这一目标。
Today, our guest is Cathy Zhu, Managing Director of China of CasperLabs. Let's talk to him to learn about CasperLabs.
今天，我们邀请到了CasperLabs中国区负责人Cathy Zhu。让我们跟随嘉宾的步伐，深入了解CasperLabs吧。
Hello Cathy , thank you for joining us for the XT.com and CasperLabs AMA!
Cathy，您好，欢迎来到XT和CasperLabs的AMA！
A：
Hi This is Cathy Zhu, Managing Director of Casperlabs for China. It is my great pleasure to be here with you. Thanks XT team for inviting me.
大家好，我是Cathty Zhu，CasperLabs中国区负责人。很荣幸能在此和大家进行分享，非常感谢XT.COM的邀请。
Q:
Can you give our audience a brief introduction of CasperLabs as well as the inspiration to build CasperLabs?
您能给我们的观众简单介绍一下CasperLabs和创建CasperLabs的灵感来源吗？
A:
I believe most of us on the team have very similar reasons why we are excited to launch this protocol. I can speak personally though.
团队中大多数人对于推出协议都感到十分激动，我认为大家都理由都是相似的，但我可以从自身角度出发讨论一下。
CasperLabs came about because we thought we could deliver a truly decentralized Proof-Of-Stake system that was developer friendly at the perfect time when such a platform was needed. Blockchain is under-penetrated with only 10-15k developers out of 26 million (0.6% penetration), things are just getting started. We’d love to contribute to helping create systems that bring mass adoption.
创建CasperLabs的初衷是因为我们认为可以在一个合适的时间点交付一个真正去中心化的开发者友好型PoS系统。全球一共有2600万名开发人员，而区块链行业只有1 - 1.5万名开发者（占比0.6%)，这才刚刚起步。我们很乐意帮助创建能够实现大规模应用的系统。
Q:
Can you introduce the core team members of CasperLabs? We hear that the team is highly experienced, can we get some examples?
您能给我们介绍一下CasperLabs团队的核心成员吗？我们听说你们的团队经验丰富，能举一些例子吗？
A:
Over 66% of our team are being engineers including scientist. I wish I had time to talk about everyone at the company, but everyone has similar backgrounds. For example, over 80% of the team have Masters and graduate degrees most from Ivy league or equivalent schools. On average members of the team have about 15 years of experience, both at leading companies like Bain Capital, Microsoft, Google, Adobe, Amazon, DropBox, but also protocols such as Ethereum, HoneyBadger, Maidsafe and several others.
我们团队有超过66%的成员是工程师和科学家，我希望能有时间谈谈公司里的每个人，不过每个人的背景都差不多。例如，超过80%的团队成员拥有常青藤或同等学校的学士学位和硕士研究生学位。团队成员平均拥有15年的工作经验，有的成员在贝恩资本（Bain Capital）、微软（Microsoft）、谷歌、Adobe、亚马逊（Amazon）、DropBox等顶尖公司工作，也有成员在以太坊（Ethereum）、HoneyBadger、Maidsafe等区块链协议公司工作。
But If I were to talk about a few:
我简单介绍几位。
1. Dr Daniel Kane: He is a renowned silicon valley mathematician who got a double bachelors from MIT and his PhD from Harvard. He is the primary author on our “highway protocol” flavor of CBC Casper which is the first mathematically provably live and secure protocol which makes no Compromises to Security.
Daniel Kane博士：他是硅谷著名的数学家，拥有麻省理工学院的双学士学位和哈佛大学的博士学位。他是CBC Casper “Highway协议”的主要作者，CBC Casper是第一个在数学上可证明的实时安全协议，不在安全性方面做出妥协。
2.Dr. Andreas Fackler, got his PhD at Ludwig-Maximilians-Universität.. He held roles at Google for several years and has also worked on the Maidsafe and Honeybadger protocols.
Andreas Fackler博士：他在慕尼黑大学获得博士学位，在谷歌任职多年，还从事过Maidsafe和Honeybadger协议的研究。
3.Medha Parlikar our CTO : decades of experience delivering production software at marquee companies such as Adobe, Omniture, Avalara, MP3.com and DivX, managing very large engineering teams.
我们的首席技术官Medha Parlikar：她有拥数十年的工作经验，曾在Adobe、Omniture、Avalara、MP3.com和DivX等知名公司从事软件开发交付工作，管理庞大的工程师团队。
Q:
In the Crypto industry, what do you think of the current state? What do you think that needs to be improved?
您认为加密行业的现状如何？有哪些地方需要改进？
A:
Every new technology takes a significant amount of time to gain mainstream adoption. Amazon AWS took 9 years to break into the mainstream and the internet took decades to become the phenomenon that it has become.
每一项新技术都需要相当长的时间才能被主流采纳。亚马逊AWS花了9年时间才进入主流，而互联网经过几十年的发展才成为有今天如此广泛的应用程度。
As a related point, Firstly, I think there are core reasons why public chains have not seen mainstream adoption yet. The developer experience is difficult and does not mirror the experiences they are used to (Esoteric and custom programming languages like solidity, plutus etc).
首先，我认为公链还没有被广泛采用有几点主要原因。开发人员积累经验很困难，而且他们以前惯用的经验无法运用到现在的工作上（Esoteric和自定义编程语言，如Solidity和Plutus等）。
In addition, there are no public blockchains that achieve scalability while maintaining full security (not just probabilistic security) and decentralization, a lot of new generation blockchains have some centralizing features as well as tendency to have very concentrated ownership structures, These are both challenges that we aim to correct.
此外，还没有任何公链能够保证完全安全（不只是概率安全）地实现扩展和去中心化，很多新链具有中心化特征，倾向高度集中的所有权结构，我们旨在纠克服这些挑战。
Q:
How does the CasperLabs team plan to tackle these issues to reach mass adoption?
CasperLabs团队打算如何解决这些问题，实现大规模的应用？
A:
let’s talk about some specific things we are doing!
来谈谈我们具体在做什么！
Firstly we have embraced open programming standards. The chart on the left shows that while solidity is the most used smart contracting language today with ~10k developers, this number is much smaller than the 26 million total developers out there.
首先，我们采用了开放式编程标准。 左图显示， Solidity是当今使用最广泛的智能合约语言，约有1万名开发人员。尽管如此，这个数字比2600万总开发人员数要小得多。
The chart on the right shows that Rust has the highest approval rating amongst programming languages (From Stack overflows survey which had over 90,000 respondents)
右图显示，Rust在编程语言中的认可度最高（调查来自Stack Overflow，有90,000多名受访者）
This is telling us that for blockchain to succeed it needs to cater to all developers and they have made their preferences for 1. broadly used and 2. well-supported programming languages very clear.
这告诉我们，区块链要想成功，就必须迎合所有开发者的需求，他们的偏好非常清晰：1. 应用广泛2. 支持良好的编程语言。
The CasperLabs blockchain supports Rust and Assembly Script right out the gate as contracting languages. This makes it very easy for developers to use familiar tools. By embracing open standards, we will be able to create a platform that welcomes all 26 million developers.
CasperLabs区块链支持Rust和Assembly Script作为合同语言。让开发人员可以轻松使用熟悉的工具。通过采用开放式编程标准，我们将能够创建一个适合2600万开发人员的平台。
Secondly we have a set of tools that significantly make the developer experience easier, including
1.Flexible payment code (Sender does not always have to pay)
2.Weighted key management (You can create any kind of threshold system)
3.Upgradeable contracts (Never lose control of your systems)
4.Direct state querying (Easy data access)
其次，我们提供了一系列工具，这些工具可以极大地简化开发人员的工作，其中包括
1. 灵活的付款代码（付款人并不总是需要付款）
2. 加权密钥管理（您可以创建任何类型的阈值系统）
3. 可升级的合同（永远不会失去对系统的控制）
4. 直接查询状态（轻松访问数据）
Glad to go into detail on any of these.
我很乐意对其中任何一个进行详细介绍。
Q:
Global technological transformation has further strengthened the demand for basic blockchain technology. There are many cross chain and alliance blockchain projects in the market. What do you think of the current public chain market? What are the advantages of CasperLabs in the field of public chain at this stage?
全球技术转型进一步提高了对基础区块链技术的需求。市场上有许多跨链和联盟区块链项目。您如何看待当前的公共链市场？现阶段，CasperLabs在公链领域有哪些优势？
A:
we view ourselves as an infrastructure layer. Similar to Amazon AWS, Microsoft Azure etc. We let application developers do whatever they choose to do. That being said we have included a huge amount of features that enable some pretty great use cases.
我们将自己视为一个基础架构层，类似亚马逊AWS，微软Azure等，让应用程序开发人员做他们想做的任何事情。而且，我们已经开发了大量的功能，这些功能支持一些非常棒的用例。
We are already in conversations with many large enterprises and startups, but I can talk about some the specific problems we are trying to solve (That have not been solved by block chain yet)
我们已经在与许多大型企业和初创企业进行对话，但是我可以谈谈我们正在努力解决的一些具体问题（这些问题尚未通过区块链解决）。
On adoption, the feedback we are receiving from businesses has been extremely positive. Our team has a background in professional software engineering for large SaaS companies, and they understand what software companies need in a technology platform. A lot of features on our platform have been created based on direct feedback from enterprises as well accumulated knowledge on the team.
在应用方面，我们从许多企业收到了非常积极的反馈。我们的团队拥有大型SaaS公司的专业软件工程背景，他们了解软件公司在技术平台上的需求。我们平台上许多功能的创建都是基于企业的直接反馈以及团队积累的知识。
Q:
Do you think CasperLabs will be “Ethereum Killer”?
您认为CasperLabs会是“以太坊杀手”吗？
A:
Firstly I think the industry is in too early stages to have clear competition. The industry in general is under-penetrated and the ethos is to be helpful to each other. I’d say we are closest in beliefs to ethereum in that we believe is a fully open and decentralized system.
首先，我认为区块链行业还处于起步阶段，尚无明确的竞争关系。总体而言，区块链的行业渗透率很低，行业精神就是互相帮助。我们的理念和以太坊最接近，因为我们相信这是一个完全开放和去中心化的系统。
We are very similar in terms of ethos. We are a fully permissionless and highly secure protocol so in that sense as smart contracting platforms we are most similar to ethereum. And in many ways we are implementing the ethereum 3.0 roadmap
我们的和以太坊的相同之处在于理念。我们是一个完全未经许可且高度安全的协议，因此从某种意义上讲，作为智能合约平台，我们与以太坊最为相似， 而且我们正在实施以太坊3.0路线图。
In terms of differences. We will be a full scalable PoS system at launch (Estimated end of the year), Ethereum will continue to be a PoW/PoS hybrid for at least a few years. The first phases of Eth 2.0 are PoW/PoS hybrids. In addition we have embraced open programming standards right out the gate, the Ethereum shift to open programming standards will be a few phases out.
当然，我们也存在差异。预计在年底发布时，我们将成为一个完全可扩展的PoS系统，而以太坊至少在未来几年内会继续是PoW/PoS的混合系统。Eth 2.0的第一阶段是PoW/PoS混合。此外，我们已经完全接受开放式编程标准，而以太坊向开放式编程标准的过渡将逐步取消。
In addition the two features I described (flexible payment code and weighted key management) and several more like CI/CD are unique to our protocol and are not yet on the ethereum development timeline.
另外，我刚刚提到的两个功能（灵活的付款代码和加权密钥管理）以及CI/CD等其他几个功能是我们CasperLabs协议的特有功能，还没有在以太坊的开发时间表上出现。
Q:
The purpose of CasperLabs is to build a revolutionary blockchain platform for all applications that need advanced security protection. So how does CasperLabs protect assets and data security on a completely decentralized public chain platform?
CasperLabs的目标是为所有需要高级安全保护的应用程序构建一个革命性的区块链平台。那么，CasperLabs如何在完全分散的公链平台上保护资产和数据安全？
A:
CasperLabs has very rigorous security standards, meaning we rely on provable Mathematical security rather than probabilistic security. This is largely aided by the cutting edge work from Drs Daniel Kane and Andreas Fackler.
CasperLabs具有非常严格的安全性标准，也就是说，我们依靠的是可证明的数学安全性而不是概率安全性，这在很大程度上得益于Daniel Kane博士和Andreas Fackler博士的前沿研究。
We are fully Byzantine fault tolerant and have considered all major attack types include 1. Cartel formation 2. Long Range Attacks 3. Equivocations 4. Double spend attacks 5. Sybil attacks etc.
我们采用的完全是拜占庭式容错机制，考虑了所有主要的攻击类型，包括：1.卡特尔形成；2. 远程攻击；3. Equivocations ；4.双花攻击；5.Sybil攻击等。
We are also immune to several DDoS style attacks that have not been uncovered by recent research. There are a family of DDoS attacks that we think most proof of stake chains are vulnerable to and have not anticipated. We will be publishing this research soon.
我们也对一些近期研究尚未发现的DDoS类型攻击免疫，我们发现大多数PoS链无法预料或抵抗一系列DDoS攻击，很快我们就会发表这项研究。
Q:
From the perspective of the market, do we need such a large number of public chains in the future? Do you think a lot of different public chains will affect ecological efficiency?
从市场的角度来看，未来是否需要大量的公链？ 您认为许多不同的公链是否会影响生态效率？
A:
In my opinion only 2 tectonic shifts (Big moments!) have happened in our industry
在我看来，我们行业仅发生了两次结构性转变（重大时刻！）
1.First tectonic shift Nakamoto consensus (Used in Bitcoin) created the digital asset. It’s not just about money and currency it is also the best form of copy protection we have ever seen.
第一次转变是中本聪共识（用于比特币）创造了数字资产。这不仅涉及金钱和货币，也是我们见过的最好的版权保护形式。
2.Second tectonic shift was the birth of smart contracting as proposed by ethereum. Now we could also make money programmable
第二次转变是以太坊提出的智能合约，现在我们可以把编程运用到金钱上。
The third tectonic shift (Or Blockchain 3.0) will happen once blockchain technology scales throughput, security and adoption. Unfortunately this has not happened yet because most attempts to scale have sacrificed true decentralization and security.
当区块链技术扩展吞吐量、安全性和应用时，第三次结构性转变（或者说区块链3.0）就会发生。但是这种情况尚未发生，因为大多数扩展都牺牲了真正的去中心化和安全性。
I think there are a lot of protocols coming out. My view is that the ones that try to create something without compromising security or decentralization are the ones that will create long term value. In the short term everything is speculative, but the real prize is when you build something that can withstand any attack and any form of control.
我认为有很多协议即将出台。我的观点是，那些试图在不牺牲安全或去中心化的情况下进行创造的人，才是能够创造长期价值的人。从短期来看，一切都是投机的，只有能够抵御任何攻击和任何形式控制的东西才是真正有价值的创造。
Q:
What is your timeline, and what can we look forward to from CasperLabs?
你们的时间表安排了哪些计划呢？我们可以期待哪些CasperLabs的项目？
A:
We started building since November of 2018.There has been almost a year and a half of development work done by a relatively large team of 30+ full time employees and dozens of advisors and consultants who have helped refine the platform.
We launched our mainnet at the end of March.
我们从2018年11月开始起步，由30多名全职员工和数十名帮助完善平台的咨询顾问组成了一个大型团队，已经进行了将近一年半的开发工作。
3月底我们推出了主网。
Right from the beginning CasperLabs has been built as a platform to help bring developers and communities together to build whatever their imaginations want to. We aim to be open infrastructure similar to AWS and enable developers and entrepreneurs to run the applications, data and contracts as they choose. CasperLabs is purpose built to give people easy to use tools and technologies to let their imaginations fly. As an industry we all have a lot to do. Lets get building!
从一开始，CasperLabs就是作为一个平台，帮助开发者和社区创建他们想创建的任何东西。我们的目标是成为类似AWS的开放基础设施，让开发人员和企业家可以运行应用程序、数据和合同。CasperLabs旨在为人们提供易于使用的工具和技术，放飞他们的想象力。身在区块链行业，我们都有很多事情要做。让我们一起来创建吧！
Q:

Q:
Anything else do you want to share with our community?
您还有什么想和我们的社区分享的吗？
A:
We are pleased with the initial community interest in the underlying technology but I will state again that we are just getting started. We will continue to engage deeply with communities and as the restrictions open up, we aim for a lot of in person events, hackathons and much much more which should see these trends accelerate even more. The next focus of CasperLabs is working on Casper ecosystem and partnerships including enterprise relations. There are a lot of really good news coming soon. Please stay tuned.
社区对基础技术感兴趣，我们对这点感到高兴，但我要再说一遍，我们才刚刚开始。我们将继续与社区进行深入互动，随着限制的开放，我们的目标是举办更多现场活动、黑客马拉松以及其他活动，这些趋势应会进一步加速。CasperLabs的下一个重点是开发Casper生态系统和包括企业关系在内的伙伴关系，很快就会有很多好消息，请继续关注我们。
