I have nearly 20 years of experience in system development and team management, served as IT director of a multinational company and project external consultant of the State Administration of Transportation.
I have been working for NULS since the end of 2018. With rich experience in using modular methods and microservices, I have led and completed the modular reconstruction of the underlying core of NULS 2.0 and the design and development of the microservice architecture with the other NTC members.
译文：各位小伙伴们，大家下午好！我是Berzeck，NULS NTC 理事成员。毕业于玻利维亚拉巴斯军事工程学院，系统工程学士学位。近 20 年系统开发和团队管理经验，曾担任跨国公司 IT 总监，国家运输总局项目外部顾问。我从2018年底开始为NULS工作，在使用模块化方法和微服务方面有着丰富的经验，主导并完成了 NULS 2.0底层核心的模块化重构和微服务架构的设计、开发。
BitZ饭饭：当前Nerve在市场上有很高的热度，能否先介绍下项目？
Everyone knows that Nerve is currently very popular in the market, so can you introduce the NVT project first?
BZ: 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.
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。
Its goal is to eliminate the isolation problem that most blockchains have. Meanwhile, 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。
BZ：Here are some INFO for Nerve:
Nerve website: http://nerve.network/Forum of the progress Nerve ：https://bbs.nuls.io/c/general/nerve-news/64Nerve WeiBo：Nerve网络
译文： 关于Nerve资讯：
Nerve官网http://nerve.network/动态进展的资讯论坛：https://bbs.nuls.io/c/general/nerve-news/64微博：Nerve网络
BZ：Nerve adopts a multi-layer and multi-chain architecture that integrates parachains and relay chains, and defines a set of interface protocols for public chain networks such as BTC and ETH, so that tokens such as BTC, ETH, ERC20, NULS, NRC20, etc. can be quickly transferred between different public chains.
This not only enables Nerve to form a differentiated competitiveness in the construction of the DeFi ecosystem, but it is also likely to become a landmark leap forward in the development of the blockchain.
译文：Nerve采用集成平行链和中继链的多层多链架构，针对BTC、ETH等公链网络定义了一组接口协议， 使BTC、ETH、ERC20、NULS、NRC20等代币可以在不同公链间实现快速转移。这不仅使Nerve在建设DeFi生态中形成差异化竞争力，同时很可能成为区块链发展历程上标志性的一次跃进。
BitZ饭饭：跨链项目也有不少，Nerve相比其他跨链项目有哪些竞争优势？
There are also many cross-chain projects. What competitive advantages does Nerve have over other cross-chain projects?
BZ：Nerve is a project in the industry that truly realizes the technology of homogeneous cross-chain, smart contract assets cross-chain and heterogeneous cross-chainat the same time, while other cross-chain projects are still under development. Therefore, in terms of technical progress and landing, Nerve is already in a leading position.
译文：Nerve是目前行业里真正同时实现同构跨链、合约资产跨链和异构跨链技术的项目，而其他跨链项目尚在研发中。因此，从技术进度与落地来讲，Nerve已处于领跑地位。
BZ：Nerve is a Integrator of DeFi, which is including: heterogeneous cross-chain + cross-chain assets staking + NDEX (decentralized exchange), etc.
译文：Nerve是DeFi集大成者，包括了：异构跨链+跨链资产质押+NDEX( 去中心化交易所)等。
BZ： Currently NerveNetwork has 7 major technical highlights:
（1）Heterogeneous cross-chain, 15 virtual bank nodes manage cross-chain assets on the underlying chain; 35 consensus nodes package transactions and generate blocks; countless underlying nodes verify mainnet transactions for the underlying community governance and substitute at any time to ensure mainnet security.
（2）It can be confirmed within 2 seconds, Meanwhile the transferring service fee is almost zero, and it is the lightning network of BTC, ETH, ERC20.
（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 realize multi-chain asset chain management, providing services for small exchanges, wallets, DApps, etc.
（6）Cross-chain Staking: It supports BTC, ETH, NULS participate in staking on the Nerve network to get NVT rewards.
（7）The concept of stable coin: through heterogeneous cross-chain technology, has the opportunity to become the capital pool of the entire blockchain world.
译文：NerveNetwork目前主要有7大技术亮点：
（1）异构跨链，15个虚拟银行节点底层链上治理跨链资产；35个共识节点打包交易并出块；无数个底层节点验证主网交易，用于底层社区治理并随时替补保证主网安全。
（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。
（7）稳定币概念，通过异构跨链技术有机会成为整个区块链世界的资金池。
BZ： 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：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；Nerve不会复制它，因为它可以使用NULS中的此功能。
BZ： 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： 因此，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!
BitZ饭饭：作为 NULS 公链的生态项目，NULS 为 Nerve 项目开发与落地带去哪些支持与帮助？Nerve 又能使得 NULS 公链获得哪些优势？ As an ecological project of the NULS public chain, what support and assistance does NULS provide for the development and landing of the Nerve project? What advantages can Nerve bring to NULS ?
BZ：NerveNetwork was born in the NULS technical community,NULS community provides Nerve with technological, business expanding, and ecological support.
译文：NerveNetwork诞生于NULS技术社区，NULS社区为Nerve提供了诸多技术、商务拓展、生态建设等方面的支持。
BZ：The online of Nerve mainnet means that in the cross-chain field, NULS ecology has landed its comprehensive technology, and will bring more ecological projects and users for NULS. When the ecology and Defi applications become more and more, it will be formed a strong ecology like a huge pool.
译文：Nerve的上线意味着：在跨链领域，NULS生态实现了全面的技术落地，并将为NULS生态带来更多的生态项目和用户。当生态和Defi应用越来越丰富时，将会形成一个庞大的蓄水池。
BZ：Nerve’s multi-asset staking design will provide NULS with real application scenarios, which will really enhance the value of NULS. Nerve supports NULS staking, In the case of equal asset value, using NULS to participate in Nerve staking, the default earnings will be twice of other cross-chain assets.
译文：Nerve的多资产质押设计，将为NULS提供真实的应用场景，实实在在地提升NULS的价值。Nerve支持NULS委托挖矿，在资产价值相等的情况下，使用NULS参与Nerve委托挖矿，默认获得的收益将会是其他跨链资产的2倍。
BZ：As an ecological project adopting the NULS technology system, Nerve will automatically support the cross-chain docking of NULS, so that NULS ecology can take the lead in enjoying the dividends brought by Nerve.
译文：Nerve作为采用了NULS技术体系的生态项目，将天然支持NULS跨链接入，从而让NULS生态率先享受到Nerve带来的红利。
BitZ饭饭：如今 DeFi 已经衍生出借贷、交易、稳定币等许多方向，Nerve 对自身 DeFi 生态的具体发展方向有怎样的计划？Nowadays， DeFi has derived many directions such as lending, trading, and stablecoins, what plans does Nerve have for the specific development direction of its own DeFi ecosystem?
BZ：Whether it is a heterogeneous cross-chain protocol, DEX, cross-chain asset staking or the following stablecoin protocol, Nerve is the hottest concept in the current industry. NVT is born for DeFi!
译文：Nerve不管是异构跨链协议、DEX、跨链资产质押或者后期的稳定币协议，都是当前行业内最火的概念，NVT为DeFi而生！
BZ：（1) Nerve main chain asset NVT can participate in staking, and other various cross-chain assets can also participate in staking. This is an innovation for Nerve in the cross-chain and Defi fields.
（2）The NDEX （Nerve decentralized exchange）application of its own (currently in public beta) will be opened after the nodes; and it will be docked to the OTC trading system later.
（3) Nerve is based on the NULS microservice architecture, and supports other projects or teams to use the Nerve module to customize their own DEX. In this low-cost way, it is realized one-click customization of DEX. Then DEXs, which are comparable to centralized exchanges in the future, may come soon.
（4) Stable coin [post-module]: Main network assets NVT and cross-chain assets (BTC, ETH, NULS) can be staked on the main network to obtain stable coins (xxx) and enter the secondary market for circulation. NVT supports the access of DAO organizations.
（5) Nerve can connect various blockchain projects simply, economically and efficiently. And it is planed that we will integrate more high quality projects and stablecoins to construct Nerve’s ecology and Defi applications in the future.
译文：（1）Nerve主链资产NVT可以参与 Staking 挖矿，而其他多种跨链资产也可以参与 Staking 挖矿。 这是Nerve在跨链和Defi领域的一大创新和尝试。
（2) 自带去中心化交易所NDEX应用（目前正在公测中），将会在节点后开放；后期会接入OTC交易系统。
（3）Nerve基于NULS微服务架构开发，支持其他项目方或团队使用Nerve模块来定制自己的DEX。通过这种低成本方式，实现DEX的一键定制。那么未来能与中心化交易所媲美的DEX可能很快便会出现。
（4) 稳定币【后期模块】：主网资产NVT和跨链资产（BTC、ETH、NULS）都可以在主网进行抵押获得稳定币（xxx），并进入二级市场 流通，NVT支持DAO组织的接入。
（5）Nerve能做到简单、经济又高效地对接各区块链项目。并计划在未来一段时间，集成更多受好评的项目以及稳定币资产，从而打造项目生态与Defi应用。
BitZ饭饭：2020年DeFi比较火热，怎么看待 DeFi 未来的发展趋势？
DeFi is hot in 2020, how do you think about the future development trend of DeFi?
BZ：The prospect of Defi is to build a decentralized financial system, to achieve the globalization of digital assets and Defi applications, so that let more people enjoy the convenient and transparent financial services.
译文：DeFi的未来：就是要构建去中心化的金融系统，实现数字资产和Defi应用在全球范围内的普及，让更多人享受便捷、透明的金融服务。
BitZ饭饭：近期许多 DeFi 类应用遭到黑客攻击，这反映出 DeFi 市场怎样的问题？Nerve 能够避免这类问题吗？
Recently, many DeFi have been attacked by hackers. What kind of problems does this reflect in the DeFi market? Can Nerve avoid such problems?
BZ： For all the DeFi projects, security is the most core element. Most of Defi is coded through smart contracts, the security and efficiency of applications running on smart contracts are not as good as programs that are hard-coded directly at the bottom. Thus, Nerve has adopted a different architecture design from Ethereum.
译文： 对于DeFi项目，安全性是最为核心的要素。大部分以太坊DeFi是通过智能合约编写的，智能合约上运营的应用程序安全性和效率都比不上直接在底层硬编码的程序。Nerve对此采取了不同于以太坊的架构设计。
BZ： Nerve does not have a smart contract， and the asset exchange protocol is supported on the chain. This protocol is directly supported in the bottom layer of the Nerve network and is jointly maintained by professional virtual bank nodes and consensus nodes. The systemic security risk is much smaller than the Defi application developed by smart contracts.
译文： Nerve没有智能合约，链上支持资产交换协议。这个协议直接在Nerve网络的底层中支持，并且由专业虚拟银行节点和共识节点共同维护，系统性安全风险要比智能合约开发的DeFi应用小得多。
BitZ饭饭：Nerve节点竞选即将开始，如何成为Nerve节点？
Nerve node election will start, how to become a Nerve mainnet node owner and participate in staking?
BZ：Nerve’s main network nodes are divided into three types: Common nodes, consensus nodes, and virtual bank.
译文：Nerve采用虚拟银行、共识节点、普通节点等三层节点模型。
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.
译文：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。
The consensus nodes are responsible for the maintenance of the blockchain.
The common nodes are responsible for functions such as transaction collecting, block and transaction verifying, and providing services for applications.
译文：共识节点负责自身区块链的维护；普通节点则负责交易的收集、验证等服务。
This kind of multi-consensus mechanism model can help different types of users have the opportunity to participate in the Nerve node consensus process, thus improve the stability and fairness of the Nerve network.
译文：这种多重共识机制模式可以帮助不同类型的用户都有机会参与到Nerve的节点共识过程中，提升Nerve网络的稳定性与公平性。
BZ： If you want to become a Nerve mainnet node owner and participate in staking, you need to hold at least 200,000 NVT. 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. If you can become the top 15, you will also become a virtual bank node. Correspondingly, you’ll get more rewards for different kind of nodes.
译文：如果您想成为Nerve主网节点，参与共识挖矿，至少需要持有20万个NVT；
如果您节点上的资产质押数量能排到全网节点的前35名，您就可以成为共识节点；
如果您能成为前15名，您将成为虚拟银行节点，这样将会有更多的收益。
BZ：In addition to self-holding NVT to establish nodes, the best way is to establish its own mining pool to attract more people to transfer the pledge rights so that you can establish nodes. In this way, it will have the lowest cost and more opportunity to rank in the top 35.
译文：除了自持NVT建立节点外，最好的方式就是建立自己的矿池，吸引更多人将质押权交给您，让您来建立节点。如此一来，您排到前35的成本最低，而且机会更大。
BitZ饭饭：Nerve搭建了自己的DEX，可以简单介绍下NerveDEX吗？
We know the Nerve has its own DEX, Can you introduce NerveDEX?
BZ：NerveDex is scheduled to be online in August. and is currently in public beta. Decentralized exchange is Nerve’s first step in creating DeFi. Nerve has been embedded the decentralized exchange (NDEX) in its underlying architecture.
译文：NerveDex计划于8月上线，目前正在公测中。去中心化交易所是Nerve打造DeFi的第一步，Nerve在其底层架构中内嵌了去中心化交易所NDEX.
BZ：Meanwhile, it supports other projects or teams to use the Nerve module to customize their own DEX. For small and medium-sized exchanges, wallets, and DApps, they no longer need to spend much efforts to develop and maintain original asset management tools. Nerve can better meet their needs for multi-asset management convenient ly and low-costly.
译文：同时, Nerve支持其他项目方或团队使用Nerve模块来定制自己的DEX。对于中小型交易所、钱包、DApp，他们可以无需再投入巨大精力开发、维护原有资产管理工具。Nerve可以更好地满足他们以低成本、快捷的方式进行多资产管理的需求。
BitZ饭饭：请问Nerve今年的发展计划有哪些，可以和我们分享一下吗？
Can you share with us the Nerve development plan of this year?
BZ：On July 10, Nerve mainnet has been launched; in mid-August, Nerve will open the nodes and staking system.
译文： 7月10日，Nerve主网已经上线发布；8月中旬，Nerve将开放节点和质押系统。
BZ： Q3 2020：NerveDEX trading platform, light wallet, staking will be available, and external interfaces will be opened.
译文：Nerve DEX、轻钱包计划于今年第三季度发布；届时，大家可以在Nerve上委托，外部接口将会陆续开放。
BZ： After that Nerve 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，Nerve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。
BitZ饭饭：相信很多用户在直播结束后，都会入手NVT，那么对于区块链投资者来说，行情涨跌永远是他们关心的大事，对于Nerve的投资者，您有何投资建议呢？
I believe that many users will buy NVT after the AMA. For the investors, the rise and fall of the market is a major thing for them. For investors in Nerve, what advices do you have?
BZ： As the DeFi heat wave continues, hundreds of DeFi projects have emerged on the market. When choosing a project, it is recommended not to blindly follow the hot spots, you must pay attention to high-quality projects and seize a good opportunity to participate.
译文：随着DeFi热浪的持续，市场上涌现了数百上千个DeFi项目。大家在选择项目时，建议不要盲目跟随热点，但一定要对优质项目保持关注，抓住一个好的时机参与进去。
以下摘录部分社区用户提问：
1、NVT的DeFi可以实现跨链DeFi,这是一个比较少的DeFi，我认为这是以后DeFi的主要方式，是如何实现的？是否完全去中心化？
BZ：Nerve standardizes the way different blockchain structures are represented allowing developers to focus on the functionality of their apps instead of worrying in the implementation details of each asset their application will support, so this is not a small part of DeFi, it is one of the most important requirement a Defi framework must have.
About decentralization, as everything in life a compromise has been made so the platform is efficient secure and fast so its not perfectly decentralized, decentralization is a process not a product and right now there is no technology that can offer full decentralization, security and efficiency at the same time.
译文：Nerve使不同区块链结构的方式标准化，使开发人员可以只专注于其应用程序的功能，而不必担心应用程序将支持的每种资产的实现细节。因此，这不是DeFi的一小部分，而DeFi中最重要的部分之一、 Defi框架必须具有的重要要求。
关于去中心化：由于生活中几乎所有事情都已经形成中心化了，平台高效、安全且快速，因此它未完全去中心化。去中心化不是一个过程，而是一种产品，目前还没有任何技术可以提供全面的安全和高效的去中心化。
2、DeFi会不会成为2020币圈理财新的风口呢？用户直接参与的DeFi是不是会和自己钱包存币一样安全？除了流动性不足外，DeFi还有哪些缺点？今后的创新方向在哪？
BZ：2020 is too soon to hope for structural changes in traditional financial services, this will take a few years. About your second question it depends of course of the quality of code and the team behind it, in our case the developers behind Nerve hava managed to create 3 blockchains that have complete different architecture microservices and WITHOUT any single serious issue on main net launch, something not even biggest blcokchain projects manage to achieve, so this is the kind of thing investors should look up to.
Disadvanatges of DeFi are the latent risk of too tight regulation from governments, bad coding quality that can make a hackers paradise.
译文：希望传统金融服务结构在2020年发生变化，还为时过早，这将需要几年时间。
关于您的第二个问题，这当然取决于代码的质量及其背后的团队，在我们的案例中，Nerve背后的开发人员成功创建了3个具有完全不同的微服务架构区块链，并且在主网启动时没有任何严重的问题，即使是最大的blcokchain项目也未能实现，这是投资者应关注到的事情。
DeFi的缺点是政府可能会实施过于严格地管控，其潜在的风险是编码质量差，这可能会引来不少黑客。
3、您觉得NVT在发展过程中遇到最大的挑战是什么？
BZ：the biggest challenge was to design a system that it is a lot simpler than competition but at the same time at least as powerful, so thats why we didn’t try to add DeFi features to NULS and instead we decided to split in 2 blockchains, which proved a very good decision.
译文：最大的挑战是设计一个比对手产品要简单得多但同时又强大的系统，这就是为什么我们不尝试向NULS添加DeFi功能，而是决定拆分为两个区块链 ，这是一个非常好的决定。
4、Nerve是基于NULS的衍生品，是否可以理解为nerve将会是更优于NULS的项目？前景以及项目落地如何？
BZ：Nerve is designed to complement NULS, instead of writting a single fat bloated blockchain that tries to do everything, we split in 2 lean and fast blockchains that have different requirements but feed from each other, for example Nerve will use some NULS’ facilities like the smart contract engine.
译文：Nerve旨在对NULS进行补充，而不是编写一个试图完成所有任务的臃肿区块链。我们将其分为2个精简和快速的区块链，这些区块链具有不同的要求但彼此相互补充，例如Nerve将直接采用NULS的智能合约等功能。
