分享环节

主持人贺源Gaga： Hello ，大家好，欢迎来到ZT Club风暴直播间。最近，有关跨链、Defi、去中心化的话题和项目持续高热。其中，广受追捧的莫过于NULS技术社区诞生的异构跨链新星NerveNetwork（社区成员称作“牛肉腿NVT”），受到了业内众多知名媒体、社群及机构的助力与关注。

那么，今天我们也非常荣幸邀请到了NerveNetowrk发起人Berzeck，由他为我们带来《异构跨链NerveNetwork，如何助力Defi腾飞》的分享。

掌声有请直播嘉宾！Berzeck，您好！请先简单介绍一下自己和Nerve吧！Berzeck, hello! Please introduce yourself  and Nerve  briefly first!

Berzeck：My name is Mario, from Bolivia, but everyone calls me Berzeck. I have 20 years of experience in software engineering and I am working for NULS  NTC  since late 2018.

译文：我叫Mario，来自玻利维亚，但大家都喜欢叫我Berzeck。我有20年的软件开发工程经验，从2018年底开始在NULS技术社区工作。

Berzeck：Nerve is a decentralized digital asset service network, which is a set of cross-chain interactive protocols based on the NULS microservices framework and developed with ChainBox. The goal is to eliminate the isolation problem that most blockchains have, also, to establish a cross-chain interoperable asset interaction network, and provide all the underlying support for Defi applications ecosystem; letting digital asset holders enjoy truly secure, free and transparent Defi application services.

译文：Nerve 是一个去中心化的数字资产服务网络。它基于NULS微服务框架， 使用 NULS ChainBox（链工厂的底层）开发搭建的区块链跨链交互协议。旨在打破区块链价值孤岛，建立跨链互通的资产交互网络，为 Defi 应用生态提供底层支持。让数字资产持有者享受真正安全、自由、透明的 Defi 应用服务。

Berzeck：NerveNetwork breaks silos of value and realize the interconnection and interworking of multiple closed blockchain systems.This process is similar to how we connect multiple Lans over a network.

译文：Nerve网络可以打破价值孤岛，实现多个封闭区块链系统间的互联互通，这个过程就像我们通过一个网络把多个局域网连接起来一样。

主持人贺源Gaga：很开心认识Berzeck ，Nerve在跨链领域取得了不错的进展，听说最近有很多好消息，您可以和我们分享一下吗？

Berzeck：Ok, thank you.Recently, be it technology, business, or ecology, NerveNetwork has made remarkable achievements: Imagination Fund, TB Capital, BitZ, and XStarPool announced they made strategic investment with NerveNetwork; There are also many exchanges that have announced or are planning to list NVT futures trading. They all deeply agree with NerveNetwork’s product positioning, recognize its technical strength and development direction, thus they are willing to join forces with Nerve to jointly promote the development and landing of the project, and willing to deeply participate in and empower projects in the maintenance of subsequent virtual bank nodes and consensus nodes.

译文：好的，谢谢主持人。NerveNetwork近期在技术、商务、生态方面取得了显著的成绩。上周获得了想象力基金、TB  Capital、BitZ、未来星矿池（XStarPool）的战略投资。另外还有多个交易所已经公告或是准备计划抢上NVT期货交易。它们非常认同Nerve的产品定位、技术实力与发展方向，愿与Nerve强强联合，共同推进项目的发展与落地。并在后续的虚拟银行节点、共识节点的维护中深度参与、赋能项目。

Berzeck：And one more good news: NerveNetwork testnet is beta, Every community members is encouraged to actively participate in the testing, to suggest, to report bugs, to share 20,000NVT rewards together.

译文：还告诉大家一个好消息：NerveNetwork已于上周开启了全球公测，欢迎大家积极参与到公测中来，提建议、寻BUG，共同瓜分20000NVT奖励。

主持人贺源Gaga：公测中的NerveNetwork目前有哪些应用呢？What are the current applications for NerveNetwork in beta?

Berzeck：NerveNetwork six major solutions:

1. Heterogeneous cross-chain, managing cross-chain assets on the underlying chain of 15 virtual bank nodes;

2. It can be as lightning network of BTC, ETH, ERC20 within 2 seconds confirming the transactions and with almost 0 service fee.

3. NerveDEX adopts the asset matching protocol on the underlying chain to realize the transparent transaction of multi-chain assets;

4. Cross-chain mainstream assets, such as BTC, ETH, USDT, etc., can use NULS VM to implement various Defi and DApp applications;

5. Docking a chain to achieve multi-chain asset chain management, providing services for small exchanges, wallets, DApps, etc.

6. It supports Cross-chain staking, the assets of BTC, ETH, NULS  can participate in staking in the NerveNetwork to get NVT as rewards.

译文：NerveNetwork目前主要有六大应用：

1、异构跨链：15个虚拟银行节点底层链上治理跨链资产；

2、2S确认，转账费用几乎为0，做BTC、ETH、ERC20的闪电网络；

3、NerveDEX：采用底层链上资产撮合协议，实现多链资产透明交易；

4、跨链主流资产：例如BTC、ETH、USDT等可以采用NULS VM实现各种Defi和DApp应用；

5、对接一条链，实现多链资产链上管理，为小型交易所，钱包，DApp等提供服务；

6、跨链Staking：支持BTC，ETH，NULS在Nerve网络参与Stake获得NVT奖励。

主持人贺源Gaga：嗯嗯，照目前的进程来看，Nerve的跨链技术应用落地已经领先于行业其他同质化项目的进度啦！

请问Berzeck，Nerve为什么选择NULS公链生态，并在跨链交互上进行搭建，而没有选择其他公链生态呢？Why does Nerve aim at NULS public chain ecology and build cross chain transactions，but without other public chain ecology？

Berzeck：Nerve is designed to complement NULS blockchain, its design is a lot simpler than other cross-chain solutions because it doesn’t try to interconnect everything with everything and also doesn’t try to incorporate all possible features, for example, smart contracts are implemented in NULS and this functionality is not replicated in Nerve because it will use this functionality from NULS.

译文：NULS拥有灵活的微服务结构， Nerve是NULS区块链生态的一个补充，它的设计比其他跨链解决方案简单得多，因为它不尝试将所有事物联系在一起，也不尝试合并所有可能的功能，例如智能合约是在NULS中实现的，但Nerve不会直接复制它，因为它可以使用NULS中的此功能。

Berzeck：So instead of having a big inefficient bloated blockchain, we split it into two slim efficient ones (NULS and Nerve) with specific purposes and tasks that are able to evolve at their own rate and designed to complement each other.

译文：因此，我们没有臃肿低效率的区块链，而是将其分为两条精配高效的区块链,各司其职，它们具有特定目的和任务，可以按自己的速度发展并相互补充。

主持人贺源Gaga：可以介绍一下Nerve有哪些技术优势吗？Can you introduce Nerve’s technical advantages?

Berzeck：No matter what technology your blockchain has now, if it doesn’t have the ability to adapt to newer technologies your blockchain is destined to be deprecated, that’s probably the only constant in technology, especially in crypto!

译文：无论你开发的区块链项目现在拥有什么技术，如果它没有能力去适应更新的技术更新迭，它将注定会被淘汰。这是技术开发中唯一不变的道理，尤其是在发展迅速的区块链行业中!

Berzeck：In this regard Nerve (and NULS) were designed from scratch with the ability to evolve and adapt faster than other crypto platforms using fewer resources thanks to its microservices infrastructure.

译文：在这方面，Nerve(和NULS)是从零开始设计的，NULS2.0采用的微服务架构，使得它能够比其他项目使用更少的资源和成本来更快地发展和适应新技术。

Berzeck：Let me put it this way, if Vitalik finds the ultimate scalability solution, while he is receiving the Turing award, we will pack the solution in a microservice and deploy it to our customers months before Ethereum, so blockchains connected to Nerve will be able to enjoy this kind of progress.

译文：让我这么说吧，如果Vitalik找到最终解决方案的可扩展性,当他获得图灵奖时,我们可以把他的方案用微服务架构的方法打包并将其部署到以太坊客户端。用不了多久,和Nerve相连的区块链就能够同步的享受到这种技术的进步了。

Berzeck：In some way, it’s like projects investing huge amounts of resources researching are effectively working for us.

译文：在某种程度上来说，这就像项目投资大量的资源研究想要获得更加高效的开发，而微服务技术就满足了这一需要，并且极大的降低了成本。

Berzeck：For example, as you can see in the screenshot, Nerve uses NULS’s 11 basic modules completely unchanged even at the binary level, which reduced most of the development effort. We just needed to develop a new Consensus module (POC+BFT), a protocol conversion module, and the node feed module.

译文：例如：正如在代码中可以看到，Nerve采用了NULS的11个基础模块，即使在二进制的级别上也完全没有改变，这减少了非常多的开发工作量，这就是微服务和模块化的好处。我们只需要开发一个新的共识模块（POC+BFT)、协议转换模块和节点喂价模块。

主持人贺源Gaga：人人都在高喊“跨链打破价值孤岛”，那么基于NULS的跨链交互新星Nerve是如何构建Defi生态，成为区块链世界的“交通枢纽”呢？Everyone believes that “cross-chain breaks the island of value”. How does the NULS-based cross-chain interactive nova Nerve build the Defi ecosystem and being “traffic hub” of the blockchain world?

Berzeck：Through the NerveNetwork cross-chain interaction protocol, only a small amount of development effort is required through using a standard interface to transform blockchains with different structures into a set of common asset types that can be recognized by cross-chain modules in the NULS ecosystem. This facilitates and enables a direct interaction between assets inside and outside of the NULS ecosystem, it also provides rich Defi usage scenarios for mainstream digital assets such as BTC and ETH.

译文：通过Nerve跨链交互协议，只需要通过标准的接口进行少量的开发，即可将不同结构的区块链转化成为一套NULS生态中跨链模块能够识别的通用资产类型。从而打通NULS生态体系内外的资产交互，同时也为主流的数字资产例如BTC等提供丰富的Defi使用场景。

 Berzeck：At a simplified level, NerveNetwork’s cross-chain interaction has two parts:

(1) NULS cross-chain ecological docking: Based on the universal NULS cross-chain protocol, all blockchain interactions in the NULS ecosystem will be realized.

(2) For independent public chains such as Bitcoin, Ethereum, and Binance Chain, NerveNetwork defines a set of interface protocols that can facilitate the interaction with these various blockchains.

 译文：Nerve的跨链交互分为两个部分：

1、NULS跨链生态对接：以通用的NULS跨链协议为基础，实现NULS大生态中所有区块链的交互。

2、对比特币、以太坊、币安链等独立的公链，Nerve定义一套接口协议，可以方便的实现各种不同区块链的交互。

 Berzeck：Taking BTC as an example, the cross-chain interaction process is as follows:

(1) Cross-chain transfer process (deposit):

  译文：以BTC为例, 上图为跨链转入流程（充值）

 Berzeck：(2) Cross-chain transfer process (withdrawal):

  译文：上图跨链转出流程（提现）

主持人贺源Gaga：Nerve采用什么共识机制？它与其他跨链项目有什么区别或优势呢？What consensus mechanisms does Nerve use?What is the difference or advantage between it and other cross-chain projects?

Berzeck：Nerve adopts POCBFT, a consensus mechanism for independent innovation.

POC refers to Proof of Credit, this is the consensus mechanism used by NULS and BFT refers to Byzantine fault tolerance.

译文：Nerve采用的是自主创新的共识机制POCBFT。POC指的是Proof of Credit，是信用共识机制的简称，是NULS创新使用的共识机制。BFT指的是拜占庭容错。

顾名思义，POCBFT是Nerve开发团队将POC和BFT结合之后的产物。

Berzeck：POC is a DPoS derived consensus mechanism that is very efficient, also it has an embedded mechanism to punish bad behaving nodes, and, of course, it allows all token holders to participate in staking and earn rewards.

译文：POC是DPOS衍生的共识机制，可以实现轮流出块，做到公平高效，它还有一个嵌入式机制来惩罚行为不端的节点。同时，也可以让所有持币人参与Staking，赚取共识激励。

Berzeck：BFT was added to the Tendermint consensus mechanism adopted by another well-known cross-chain project: Cosmos. Its performance is about 6 ~ 8 seconds while Nerve will likely reach a block speed of about 1 ~ 3 seconds.

译文：BFT加入了另一个著名跨链项目Cosmos采用的Tendermint共识机制。它的性能大约是6 ~ 8秒，而Nerve将可能达到大约1 ~ 3秒的块速度。

Berzeck：It can be seen that the combination of POC and BFT not only allows Nerve to inherit the advantages of the NULS POC consensus mechanism, but also allows Nerve to have an excellent performance.

译文：可以看出POC和BFT结合，不仅让Nerve继承了NULS POC共识机制的优点，也让Nerve在性能上有了更加优异的延伸。

主持人贺源Gaga：Nerve主链资产NVT 的最大供应量是多少?   What is the maximum supply of Nerve cord asset NVT？

Berzeck：NVT’s maximum supply is 2.1 billion, with an initial circulation of 1.1 billion (1 billion will be generated by consensus nodes and virtual banks).

译文：NVT发行最大总量为21亿枚，初始发行量为11亿枚，10亿枚通过共识节点和虚拟银行产出。

主持人贺源Gaga：NVT的代币经济、代币分配模型具体是什么样的呢？So what is the economic model of the NVT?

Berzeck：Let’s begin with the intial distribution,we use it for early development .It’s used for community construction in the early stage,as well as the recruitment of virtual banks. We will  also airdrop 10 million NVT  to NULS holders on 12nd,July.Besides,300 million NVT will be used for cornerstone investment,we are seeking for more institutions and partners.The last part with an amount of 600 million NVT is used for Foundation,200 million of them will permanently stake in virtual bank nodes.And 400 million are gradually unlocked monthly one year later after the mainnet launch in 20 months.More details can be found in the chart.

译文：初始发行11亿的分配情况可在表中清楚的看到，前期最多3.1亿流通。比重较大的基金会部分，有2亿会永久在虚拟银行中锁仓，保证网络和链上资产安全运行；有4亿会在主网上线一年后每月线性解锁，20个月解锁完毕。

Berzeck：As can be seen from the table above, after the Nerve mainnet launch, TPS will be about 2000+, which is also known as the “nerve network”, “lightning network” to be one of the technical witness.

译文：从上表可以看出，Nerve主网上线后，TPS大约在2000+左右，这也是称之为“神经网络”、“闪电网络”的技术见证之一。

主持人贺源Gaga：前面提到有其中的10亿是由共识节点和虚拟银行 产生，请问Berzeck，如何才能成为Nerve主网节点获取挖矿收益呢？How to become a mainnet node of Nerve to get mining rewards?  

Berzeck：Nerve’s main network nodes are divided into three types: ordinary nodes, consensus nodes, and virtual bank.

译文：Nerve的主网节点分为三种类型：普通节点，共识节点，虚拟银行。

Berzeck：The ordinary nodes are responsible for functions such as transaction collecting, block and transaction verifying, and providing services for applications.Ordinary nodes will allocate consensus incentives based on the proportion of pledged assets in the pledged assets of the entire network.

译文：普通节点:普通节点负责交易的收集、区块和交易验证、为应用提供服务等功能。普通节点会根据质押的资产占全网质押的资产的比例，来进行共识激励的分配。

Berzeck：The consensus nodes are responsible for the maintenance of the blockchain, and the mortgage deposit can be used to create the consensus node. The deposit cannot be less than 200,000 NVT. The number of consensus nodes on the Nerve main-net is fixed at 35, and the main-net will choose the 35 nodes with the highest deposit to become consensus nodes.

译文：共识节点：共识节点负责区块链的维护，抵押保证金才能创建共识节点，保证金不可以低于20万NVT。Nerve主网的共识节点数量固定为35个，主网会挑选保证金最高的35个节点成为共识节点。

Berzeck：The virtual bank is responsible for the maintenance of cross-chain assets, including the creation and management of multi-signature accounts or smart contracts for parallel chains, the creation and broadcasting of asset transfer transactions, etc.The virtual bank is selected from the consensus nodes, and the default is the top 15 consensus nodes with the largest deposit The weight of the virtual bank’s reward is twice that of the consensus node.

译文：虚拟银行:虚拟银行负责跨链资产的维护，包括创建和管理平行链的多签账户或智能合约，创建并广播资产转出交易等。虚拟银行从共识节点中选出， 默认为共识节点中保证金金额最多的15个共识节点。虚拟银行的收益权重比共识节点更高。

Berzeck：if you want to become a Nerve mainnet node owner and participate in staking, you need to hold at least 200,000 NVT.

译文：如果你想成为Nerve主网节点，参与委托挖矿，至少需要持有20万个NVT。

Berzeck：If the number of asset pledges on your node can be ranked in the top 35 of the entire network, you can become a consensus node.

译文：如果你的节点上的资产质押数量能排到全网节点的前35名，你就可以成为共识节点。

Berzeck：If you can become the top 15, you will also become a virtual bank node, You’ll get more bang for your buck.

译文：如果你能成为前15名，你将成为虚拟银行节点，这样你将会有更多的收益。

主持人贺源Gaga：可以交流下NVT的生态经济是什么情况吗？What is the ecological economy of the NVT?

Berzeck：Of course,my pleasure!

At the moment,NVT will be used in four aspects.

Gas burning:paying for cross chain settlements and handling fees for transactions;

Governence tool: voting rights for Nerve ;

DEX:repurchase and destroy the transaction fees of the decentralized exchange;destroy the fees for creating transactions pairs in the decentralized exchange;destroy the fees for creating assets in the decentralized exchange;

Node:deposit for creating nodes.

译文：主要有以下四点：

燃料费：跨链结算的费用，链上转账的费用；

链上治理：Nerve 项目的投票权，链上治理工具投票权益；

DEX：链上交易手续费，去中心化交易所的交易手续费回购销毁，去中心化交易所创建交易对费用销毁，去中心化交易所中创建资产费用销毁；

节点：节点创建的抵押押金。

主持人贺源Gaga：Nerve今年的发展计划有哪些，可以和我们分享一下嘛？What are the growth plans for Nerve this year?   

Berzeck：Sure!We’ve got NDEX open;

In the near future， we plan to invite top platforms and institutions in the industry to serve as bank nodes.

译文：我们已经公告了NDEX全球公测；

近期，我们计划邀请业内顶级的平台或和机构作为虚拟银行节点。

Berzeck：July 2020：Nerve’s main-net will be released

Q3 2020：NerveDEX trading platform, light wallet, staking will be available, and external interfaces will be opened.

译文：今年七月，我们将发布Nerve的主网；

第三季度，我们将发布Nerve DEX、轻钱包。在那时，大家也可以在Nerve上委托，外部接口将会陆续开放。

Berzeck：After that we will continue docking more blockchains. In the near future, Nerve users will access seamless to various assets of BTC, ETH, ERC20, NULS, NRC20 and NULS parallel chains, and there are plans to support more mainstream blockchains.

译文：同时，我们将努力对接更多的区块链使用Nerve。在不久的将来，Nerve用户将可以实现无缝接入BTC、ETH、ERC20、NULS、NRC20、NULS平行链的各种资产，而且我们也有计划支持更多主流的区块链。

主持人贺源Gaga：非常期待Nerve的到来！问一个大家都关心的问题，如何才能获得Nerve主网资产（NVT）呢？How do we  get Nerve tokens (NVT)?  

Berzeck：NeverNetwork initiated the NULS holder 10:1 airdrop and planned to take a snapshot at NULS main network height 2620000 (approximately 12 July 2020).At present, there are many exchanges and institutions to support the air drop.

译文：NeverNetwork已经公告对NULS持有人进行10：1空投，计划在NULS主网高度2620000（大约是2020年7月12日 ）进行快照。目前已有多家交易所及机构支持本次空投。

Berzeck：Next，If you hold BTC、ETH、or NULS, you can get NVT rewards by staking them on NerveNetwork.

译文：接下来，主网上线以后，如果你持有BTC、ETH或NULS，你可以用他们参与NerveNetwork的Staking获得NVT奖励.

Berzeck：For other real-time campaign rewards, Please Check out the bbs.nuls.io — Nerve News channel and follow our twitter account @nerve_network
