Sebastian博士你好，在开始之前可以先简单的介绍一下您的团队和项目吗？
Hello Dr. Sebastian, can you briefly introduce your team and project before starting?
Sebastian：Hi thanks for having me here, were a team of 14 people based in Switzerland working on the privacy project HOPR.
嗨，谢谢你邀请我来这里，我们是一个14人的团队，总部设在瑞士，致力于隐私项目HOPR。
Jimmi：Thanks to Dr. Sebastian’s introduction, Lets start!
感谢Dr. Sebastian的介绍，我们AMA的提问环节正式开始!
Jimmi：The first question! Please briefly describe the HOPR protocol. For example, what can HOPR do? What is metadata? What is the significance of metadata privacy protection? What is the background to HOPR’s founding?
第一个问题，请您简单的描述一下HOPR Protocol是什么，它是在什么样的背景下诞生的？它能做什么？元数据什么？元数据隐私保护的意义是什么？
Sebastian：The HOPR protocol allows users to run nodes which form a peer-to-peer privacy network. Data can be sent through the network without exposing the metadata — information like who sent and received the data, when it was sent, and how much and what kind of data was involved. This is vital, because metadata can be used by malicious actors in all kinds of attacks, from hacks to unwanted user profiling.
HOPR是一个允许用户运行点对点的隐私网络节点的协议，它可以通过网络发送数据而无需暴露元数据。元数据可以描述为发送和接受数据的对象、发送数据时间、发送数据的数量、发送数据的地址等等。保护元数据是至关重要的，因为元数据可以被恶意行为者用于各种网络攻击中，比如黑客攻击或者用户配置文件攻击。
HOPR was founded in Switzerland in Spring 2020, we attracted Binance as lead investor in our seed round after having been granted a Binance Fellowship already in 2019.
2020年春季HOPR在瑞士成立，2019年获得币安奖学金，同时币安也是HOPR种子轮的主要投资者。
Jimmi：Very nice answer, Metadata is data used to describe data, most user have been ignoring its value, so their privacy has been leaked, so it makes huge sense to protect metadata privacy .
非常棒的回答，所以说元数据就是用来描述数据的数据，但是大多数的用户都忽略了它的价值，从而导致自身隐私信息的泄漏。所以HOPR在保护元数据隐私这件事上很有意义。
Jimmi：Next question.Please briefly describe the technical architecture of the HOPR, including the messaging and payment layers. Compared with privacy chat apps such as Telegram and Signal, what does the protocol layer solve?
第二个问题，请简单解释一下HOPR Protocol的技术架构，消息层和支付层都承担什么功能？与我们熟悉的诸如Telegram, Signal这些隐私聊天APP相比，协议层解决的是哪些问题？
Sebastian：The messaging layer handles data transmission throughout the HOPR network. Data packets “hop” through the network, being mixed at each stage. The HOPR proof-of-relay mechanism ensures that data reaches its destination without anyone knowing the identity of the sender and receiver or the full route the data took.
消息传递层是负责处理整个HOPR网络中的数据传输。数据包通过网络“跳跃”在每个信息传递阶段混合，并且HOPR的proof-of-relay机制可确保数据到达目的地而无需其他人知道发送方和接收方的身份或数据所经过的完整路径。
Node runners are rewarded in HOPR tokens for relaying data. This is handled by the payment layer. The payment and messaging layers are deliberately kept separate to ensure that payments can’t be linked to individual messages. This is a common way that metadata is leaked via blockchains, and by severing this link we ensure that HOPR can provide privacy without being a privacy token.
通过运行节点传递数据的用户将会获得HOPR代币奖励，这个是由支付层处理。 支付层和消息传递层有意分开设置是为了确保付款不会链接到单个信息，因为这是一种元数据通过区块链泄漏的常见方式。通过区分消息传递层和支付层，我们就可以让HOPR不用作为隐私代币就能提供隐私。
Telegram and Signal focus on end-to-end encryption, which is an important part of data privacy, but does little to protect metadata. Metadata exposes your privacy, even if the content of your message is protected.
Telegram and Signal
Telegram 和 Signal专注于端到端加密，这是数据隐私保护的重要组成部分，但对元数据的保护作用却不大。打个比方，即使用户在使用邮件时的邮件内容受到保护，元数据也会暴露用户的隐私，比如发件时间、地址、内容大小等。
HOPR isn’t just limited to chat. The messaging layers can handle any kind of data, not just what we’d normally consider “messages” in everyday usage.
消息传递层可以处理任何类型的数据，不仅限于我们通常在日常使用的“消息”。
Jimmi：Good answer, The third question is what is the difference between the HOPR protocol and other privacy messaging protocols? Does it only provide privacy for metadata?
非常棒的回答，HOPR和其他的隐私消息传递协议有什么不同？它是只针对元数据的隐私保护吗？
Sebastian：There are several privacy-preserving messaging protocols but they usually focus on some specific layer or application. For example, Matrix is a fantastic protocol that is used in many real-time communication networks. But with HOPR we are providing a foundation on top of which other protocols can operate with network-level privacy. In this way HOPR is complementary to a lot of protocols like Matrix but HOPR also provides network-level privacy for blockchain application for truly private transactions — on-chain and off-chain, that’s why we call it a layer 0 protocol.
有许多隐私消息传递协议通常专注于某些特定的层或应用程序。例如，Matrix是一个很棒的协议，已在许多实时通信网络中使用。但是，HOPR可以为其他协议在网络级隐私下运行提供基础。 这样的话，HOPR就可以创造出许多类似Matrix的协议，并且HOPR也为区块链应用程序提供了网络级隐私，提供真正的链上或者链下的私人交易，这就是为什么我们将HOPR称为layer 0协议。
Jimmi：We believe the HOPR protocol will be integrated into many DApps and DeFi products in the future as the protocol layer for data privacy transmission. Next question, How will these DApps interact with the HOPR protocol?
我们相信作为数据隐私传递的协议层的HOPR Protocol未来会集成到很多的DApp及DeFi产品中，下一个问题是请问这些DApps未来将如何与HOPR Protocol展开合作？
Sebastian：I hope to see integration into Ethereum (and other chains’) wallets, nodes and hosted services. In that way your wallet would send transactions through HOPR to an Ethereum full node or a service provider like Infura or Alchemy without giving them access to information that they should not have in the first place. In a privacy-respecting DeFi world, nobody should know your IP address and know that you, e.g., just sent money to a DEX.
我希望与以太坊上和其他公链上的钱包，节点和托管服务集成。 这样用户的钱包将通过HOPR就可以将交易发送到以太坊上的完整节点或者Infura和Alchemy之类的节点服务提供商，并且不会让他们有权限去访问他们本来不应该拥有的用户信息。 在尊重隐私的DeFi世界中，没有人会知道用户的IP地址，比如，没有人会知道某个用户在某天把数字资产发送到了某个交易所。
Jimmi：Thanks for your clear answer! HOPR received grant support from the Web 3 Foundation in 2019, and gained a lot of attention in the Polkadot ecosystem. On the other hand, you definitely hope that more developers can join you and build a product based on the HOPR protocol. Will it help the developer community and the non-developer community? Do you have plans to cooperate with more developers or the Polkadot project? What are your plans for the next parachain slot auction?
感谢您清楚的解释！在社区层面，我们看到HOPR在2019年获得了Web 3基金会的Grant支持，在波卡生态社区获得了大量的关注。另一方面，你们肯定也希望更多开发者能加入你们，搭建基于HOPR protocol的产品，你们有计划和更多的开发者或者波卡项目进行合作吗？对于接下来的平行链插槽拍卖你们有何计划？
Sebastian：HOPR did receive a grant to build a payment layer implementation of HOPR for the Polkadot ecosystem in Substrate. We appreciate the efforts of Polkadot and are actively exploring more scalable chains than mainnet Ethereum. That’s why we also ran testnets on other side chains such as xDAI, Matic, Binance Smart Chain and Ropsten.
HOPR确实获得了Web 3.0 Grant的拨款，并且构建了Polkadot生态系统以Substrate为模版的HOPR的支付层。 我们很感谢Polkadot的努力，我们也正在积极探索除了以太坊主网以外其他的可扩展网络。 这就是为什么我们还在其他侧链（例如xDAI，Matic，Binance Smart Chain和Ropsten）上运行测试网的原因。
We plan to support the developer community with APIs, SDKs and developer documentation and tooling and are also looking forward to the first apps that are useful to non-developers.
我们计划通过API，SDK，开发人员文档和工具为开发人员社区提供支持，并且也会上线对非开发人员有用的首批应用程序。
Our initial launch will be on Ethereum and maybe other EVM chains first before we explore other chains like Polkadot and therefore we will not participate in the next parachain slot auction.
我们的首次发布将先在以太坊和其他EVM链上进行，然后再探索Polkadot等其他链，因此我们不会参与下一个平行链插槽拍卖。
Jimmi：Very nice answer, the next question is how can users participate in the HOPR ecosystem? What are the benefits for HOPR token holders, and how can they get more tokens?
解释的非常好，下一个问题是用户怎样参与到HOPR生态中去呢？对于代币持有者来说，如何可以获得更多收益？
Sebastian：Users can participate in the HOPR network by running a HOPR node. It’s easy to run a node on almost any device, and we also have a plug-and-play hardware node available. Users can stake HOPR tokens to receive more HOPR tokens as a reward for relaying data.
用户可以通过运行HOPR节点来参与HOPR网络。用户可以在任何设备上运行节点，而且我们还提供了即插即用的硬件节点。用户可以通过质押HOPR代币就可以接收更多HOPR代币，作为传输数据的奖励。
Once the HOPR protocol is feature complete, the development team will switch to working on an API which will allow people to build dApps on top of HOPR.
一旦完成HOPR协议的功能，开发团队将转而使用户可以在HOPR之上构建Dapp的API。
Jimmi：Good answer, Next question is related to HOPR token. Does the HOPR token have any functions besides being used for node rewards? For example, is HOPR also a governance token? How will the HOPR token sustain its value in the long run?
很清楚的回答,下一个问题是代币经济方面的，请问代币HOPR除了用于节点奖励，它也是治理代币吗？它还有其他什么功能吗？HOPR的价格长期上涨的逻辑是什么？
Sebastian：The HOPR token has three main uses: Users can pay with HOPR tokens to send data through the HOPR network privately and securely.
HOPR代币具有三个主要用途：用户可以使用HOPR代币进行支付，以通过HOPR网络私密安全地发送数据。
Node runners can stake HOPR tokens in their nodes to be rewarded for relaying data. Node runners receive fees in HOPR for the data they help to relay, including a large number of tokens distributed in the form of cover traffic - arbitrary data which helps boost metadata privacy for everyone in the network by obscuring usage levels.
节点运行者可以将HOPR代币质押节点中，以获得传输数据的奖励。 节点运行者通过以掩护流量形式帮助传输大量数据，掩盖使用级别，从而提高网络中每个人的元数据隐私性。
Finally, the HOPR token gives users voting power in the HOPR Association DAO, launching at the end of 2021.
最后，HOPR代币将会赋予社区成员在2021年底启动的HOPR DAO中的投票权。
As metadata privacy becomes increasingly important, the demand for technology like HOPR is only going to increase. Billions of gigabytes of data are sent every hour, and this figure is only going to grow. This represents an enormous market for HOPR in the medium and long term.
随着元数据隐私变得越来越重要，对于像HOPR这样的技术的需求只会增加。 当前每小时都会发送数十亿千兆字节的数据，并且这个数字只会不断增长。 从中长期来看，HOPR还有巨大市场。
Jimmi：Very nice answer, we also believe the point that metadata privacy will become more important than ever before. Next is the eighth question: According to the roadmap, the HOPR DAO will be launched in the second quarter of this year. Can you explain HOPR’s plan for transitioning to DAO governance? What authority does the current HOPR Genesis DAO hold?
非常棒的回答，我们也相信元数据隐私会在未来变得越来越重要。接下来是第8个问题，在Roadmap上看到，HOPR DAO将在今年第二个季度发布，能否为我们具体讲解下HOPR Protocol的DAO治理计划？当前的HOPR Genesis DAO的治理权限范围是什么？
Sebastian：The HOPR Genesis DAO was given full control over the distribution of the 85m tokens in the public allocation fund. This was the sole function of the Genesis DAO, and it performed it admirably. It’s currently uncertain whether the Genesis DAO will be called upon to make new decisions.
HOPR Genesis DAO完全控制了公开募集过程中的8500万个代币的分配。 这是Genesis DAO目前的唯一功能。 目前尚不确定Genesis DAO是否会做出新的决定。
The full HOPR Association DAO will be launching later in the year, in time for our first mandated annual general meeting. This will be a full-blown DAO with tokenized voting for all HOPR token holders. Unlike other projects where token holders are limited to technical decisions like adjusting parameters, we plan to tokenize almost every aspect of HOPR governance. For example, token holders will be able to vote on the constitution of the HOPR board.
完整的HOPR DAO将在今年后半年启动，届时我们的也会召开第一次年度社区成员大会。 这将会成为一个成熟的DAO组织，对所有HOPR代币持有者进行代币化投票。 与其他项目（代币持有者仅限于技术决策，例如调整参数的治理）不同，我们计划对HOPR治理的几乎每个方面都进行代币化。 例如，代币持有者将能够对HOPR委员会的组成进行投票。
Jimmi：The next question is the one of which investors are most concerned about, We noticed that the HOPR Genesis DAO voted to hold a public token distribution starting on February 21st. The entire process is divided into three stages. Can you tell us more about them?
接下来是投资者最关心的问题之一，我注意到根据HOPR Genesis DAO投票得出代币公募方案将从本月的21号开始，整个公募过程分为3个阶段，能详细的说明一下这三个阶段吗？这样安排的好处是什么？
Sebastian：Certainly. The three phases of the HOPR public launch are designed to balance rewarding our loyal community, finding a price for the HOPR token and establishing long-term liquidity.
当然！ HOPR公开发行的三个阶段目的是为了奖励我们的早期的社区成员，并也是为了HOPR代币建立价格发现和提供长期的流动性。
In Phase 1, Genesis DAO members were able to buy an equal share of 50 million HOPR tokens (16,000 each).
在第1阶段，Genesis DAO成员能够平等地购买5000万个HOPR代币（每个地址16,000个）。
In Phase 2, 30 million HOPR tokens will be placed in a Balancer Liquidity Bootstrapping Pool, balanced against the capital raised in Phase 1. This is the first time the HOPR token will be publicly available and will serve as a price-finding exercise. Phase 2 runs from February 24th to February 27th.
在第2阶段中，将在Balancer流动性池中放置3000万个HOPR代币，与第1阶段中筹集的资金保持平衡。这是HOPR代币首次公开发行，也是HOPR代币一次价格发现， 第二阶段从2月24日持续到2月27日。
Finally, in Phase 3 the DAI and HOPR in the LBP at the end of Phase 2 will be transferred to a Uniswap pool, along with 5 million HOPR tokens provided as liquidity mining incentives.
最后，在第3阶段中，LBP的DAI和HOPR在第2阶段结束时将被转移到Uniswap池中，同时提供500万个HOPR代币作为流动性挖矿的奖励。
Jimmi：Very clear answer. Next is the final question of stage one. The most recent HOPR testnet, Titlis, was launched on January 19th, the first time the messaging and payment layers were tested simultaneously. Can you briefly describe the performance of the testnet? Did it meet your expectations?
回答的很清楚，接下来是最后一个问题，从你们的medium中了解到，HOPR Protocol主网上线之前的最后一个测试网Titlis在1月19号就启动了，并且同时运行了消息层和支付层，到目前为止也运行了整整一个月了，能简单的聊一下测试网得到的数据结果表现如何？符合你们的预期吗？
Sebastian：Our testnets have all been a great success, and Titlis was no exception. We had over 1,000 participants and were able to conduct some great load testing on the network, including seeing how certain features like automatic route finding and channel opening behave at scale, something which we’re unable to do internally.
我们的测试网都取得了巨大的成功，Titlis 也不例外。 我们有1000多名参与者，并且在网络上进行一些很棒的负载测试，比如自动路由查找和渠道开放等某些功能的大规模运行，这是单单靠我们内部团队是无法做到的。
The dev team have used this data to finalise our HOPR Jungfrau release, which is due to go live before the end of the month.
开发团队将使用这些数据来最终确定我们的HOPR Jungfrau版本，该版本将在本月底前发布。
Jimmi：Thanks to the Dr.Sebastian for his wonderful sharing. Our first stage of the theme QA comes to an end, and then we enter the free QA stage. Group friends can freely ask questions to guests, and guests are free to choose 4-5 questions to answer. The small partners who are selected for the question will share a reward of 50U worth of HOPR tokens. Then our freedom issue now begins.
感谢的Sebastian博士的精彩分享，我们第一阶段的主题问答先告一段落，接下来进入自由问答阶段。群友可以对嘉宾自由提问，嘉宾自由选择其中4-5个问题进行回答。被选中问题的小伙伴，将会共同瓜分价值50U的HOPR token奖励。那我们的自由问题环节现在开始：
【自由问答环节】
问：Is the principle of metadata privacy protection the same as that of tonardo? Can anonymous transactions be realized by HOPR?
请问元数据隐私和tonardo的原理一样吗，可以实现匿名交易吗？
Sebastian：There are several on-chain privacy projects such as Tornado Cash, Zcash and many others. So far, they are all lacking a network-level privacy solution for full-stack privacy. Privacy is only really meaningful if it is seen holistically and thus HOPR is complementary to all these on-chain solutions and in an ideal world you would broadcast your Tornado tranasactions through HOPR.
有几个链上隐私项目，例如Tornado Cash，Zcash等其他项目。 到目前为止，他们都缺少用于全栈式的网络级隐私解决方案。 整体来看，完整的隐私才是真正有意义的，因此HOPR是所有这些链上解决方案的补充，并且在理想的情况下，用户应该通过HOPR来传递Tornado 的交易。
问：When and how does hopr node mining run? Will the members of Genesis Dao become nodes?
HOPR节点的挖矿什么时候怎么运行，创世Dao的成员会变成节点吗？
Sebastian：HOPR node runners will not actually run a miner but a relayer - they are relaying traffic on the HOPR network and are rewarded for that in HOPR tokens. The HOPR network will launch next week after token distribution finished. But cover traffic incentives (similar to staking rewards) will only be active in 2-3 months so that we can have a smooth soft-launch of the protocol.
Anyone who has HOPR tokens is encouraged to run a HOPR node.
HOPR节点运行程序实际上不会运行挖矿而是中继程序-他们在HOPR网络上传送流量，并为此获得HOPR代币奖励。 代币分发完成后，HOPR网络将在下周启动。 但是奖励措施（类似于质押奖励）会在2-3个月内生效，以便我们可以顺利进行协议的软启动。我们鼓励所有具有HOPR代币的人运行HOPR节点。
问：Because your tilt test network has the most comprehensive data and the longest test time, using the BSC network, will it be integrated into the BSC public chain first?
因为你们的tilt测试网的数据最全面，测试时间也是最长的，用的是BSC网络，所以接下来会首先集成到BSC公链上吗？
Sebastian：After HOPR has crashed the Binance Smart Chain endpoint we will not launch on BSC but will actually work on the xDAI chain for launch. But mid term we hope that the gas fees on Ethereum will go back to much lower levels (for example with Layer 2 solutions such as Optimism) and we will be able to run HOPR on main net Ethereum.
HOPR使Binance Smart Chain端点崩溃后，我们将不会在BSC上启动，实际上我们将在xDAI链上启动。 但是从中期来看，我们希望以太坊的汽油费能够回到更低的水平（例如，使用诸如Optimism之类的第2层解决方案），并且我们希望能够在主要以太坊上运行HOPR。
问：How is the initial ratio of LBP determined? Is it the first phase of the fundraising xDAI and 30 million HOPR?
LBP的初始比例是怎么确定的呀，是用第一阶段的募资xDAI和3000万的HOPR吗？
Sebastian：The initial price on LBP is determined by the LBP mechanism: All xDAI raised in the public presale is converted into DAI and then together with all available HOPR token (30000000) the starting price is determined by the maximal weights (96:4) which leads to a starting price of $1.9 on LBP. However, it is important to understand that the starting price has no meaning for an actual market price. We do not recommend anyone to buy the starting price. Wait for LBP price to get lower and if nobody buys then the price should be at reasonable levels within 12-24 hours after start. That is the way how a price finding starts and that is why we think Balancer LBP is the best way to launch a token in early 2021 (year of the `0x` :)
LBP的初始价格由LBP机制确定：在公开预售中筹集的所有xDAI都将转换为DAI，然后与所有可用的HOPR代币（30000000）一起由最大权重确定起始价格（96： 4）这导致LBP的起始价格为1.9美元。 但是，重要的是要了解起价对实际市场价格没有意义。 我们不建议任何人购买起价。 等待LBP价格降低，如果没有人购买，那么价格应在开始后的12-24小时内处于合理水平。 这就是发现价格的方式，这就是为什么我们认为Balancer LBP是2021年初（`0x年:)发行代币的最佳方法的原因。
问：Do I still have a chance to become a member of genesis Dao?
请问现在还有机会成为genesis Dao 成员吗？
Sebastian：Unfortunately you cannot become a member of the Genesis DAO anymore. The Genesis DAO is available to eveyone who participated in the HOPR testnets - a total amount of 3344 people, over 90% of them participated in the this presale, so this was a huge success that we really did not expect and we are looking forward to the next phase of the HOPR token launch on Balancer LBP that is open to everybody.
不幸的是你不能再成为创世道的一员了。GenesisDAO提供给每一个参与HOPR测试网的人——总共有3344人，超过90%的人参与了本次预售，因此，这是一个巨大的成功，我们真的没有想到，我们期待着下一阶段的HOPR令牌推出LBP是开放给大家。
Sebastian：Thank you for hosting us here, were looking forward to see you all on LBP Uniswap very soon :-)
感谢您在这里接待我们，我们期待很快在LBPUniswap见到您：-）
Jimmi：Great, the AMA is over today，thanks to Dr.Sebastians sharing.
