微博：Nerve网络

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。

【AEX Quera】：Berzeck, please help us introduce what NerveNetwork is?

【Berzeck】：NerveNetwork 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. 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.

Here are some INFO for Nerve:

Nerve website: http://nerve.network/

Forum of the progress Nerve ：https://bbs.nuls.io/c/general/nerve-news/64

Nerve WeiBo：Nerve网络

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.

②

【Berzeck】：NerveNetwork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，NerveNetwork已处于领跑地位。Nerve是DeFi集大成者，包括了异构跨链+跨链资产质押+NerveDEX( 去中心化交易所)等。

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）2秒确认，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Staking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。

NerveNetwork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；NerveNetwork不会复制它，因为它可以使用NULS中的此功能。

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!

【AEX Quera】：There are also many cross-chain projects. What competitive advantages does NerveNetwork have over other cross-chain projects?

【Berzeck】：NerveNetwork 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.

NerveNetwork is a Integrator of DeFi, which is including: heterogeneous cross-chain + cross-chain assets staking + NerveDEX (Nerve decentralized exchange), etc.

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.

NerveNetwork 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 NerveNetwork because it will use this functionality from NULS.

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!

【AEX小凤仙】：如今 DeFi 已经衍生出借贷、交易、稳定币等许多方向，NerveNetwork 对自身 DeFi 生态的具体发展方向有怎样的计划？

【Berzeck】：NerveNetwork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！

（1）NerveNetwork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NerveNetwork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NerveDEX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）NerveNetwork基于NULS微服务架构开发，支持其他项目方或团队使用NerveNetwork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）NerveNetwork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。

【AEX Quera】：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?

【Berzeck】：Whether it is a heterogeneous cross-chain protocol, DEX, cross-chain asset staking or the following stablecoin protocol, NerveNetwork is the hottest concept in the current industry. NVT is born for DeFi!

（1) NerveNetwork 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 NerveDEX （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) NerveNetwork 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) NerveNetwork 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.

【AEX小凤仙】：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？NerveNetwork 能够避免这类问题吗？

【Berzeck】：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。

NerveNetwork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。

【AEX Quera】：Recently, many DeFi applications have been attacked by hackers. What kind of problems does this reflect in the DeFi market? Can NerveNetwork avoid such problems?

【Berzeck】：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.

NerveNetwork 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.

【AEX小凤仙】：据悉，NerveNetwork节点今日已经开放了，那么如何成为NerveNetwork节点呢？

【Berzeck】：是的，NerveNetwork的节点和Staking等功能已于今日正式上线了。对于目前参与NVT 挖矿的成员来说，是非常划算的。因为早期参与人数少、获得的红利会更多。

Nerve网络每天产生43200个区块，每个区块产生2个NVT奖励（每间隔100天，区块奖励按照0.822%递减）。相当于初期每天有86400个NVT奖励。为保证初期奖励的公平，给社区的用户更多时间准备，NerveNetwork将在 135万高度（UTC+8时间：2020年8月11日8点） 时开始计算共识和staking奖励。实际产生奖励的日期为8月11日，奖励发放在8月13日（奖励延迟1.5日发放）。

NerveNetwork的奖励产出是一个大矿池，所有参与者均在这个矿池中挖矿、分享收益。根据参与者质押金额、权重、当前网络高度、所有网络权重值以及节点信用情况，按照奖励计算公式每天进行一次收益结算和发放。

Nerve网络采用虚拟银行、共识节点、普通节点等三层节点模型。不同类型的节点在网络中承担的职责有所不同，由于责任区别，因此在获得收益时不同类型节点的权重也有所不同。

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；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。

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。

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。

除了自持NVT建立节点外，最好的方式就是建立自己的矿池（例如钱包和交易所），可以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。

【AEX Quera】：It is reported that the NerveNetwork nodes has been online today, so how to become a NerveNetwork node?

【Berzeck】：Yes. NerveNetwork nodes & staking functionalities is Online today!For the early participants, it is very cost-effective for staking, because the number of early participants is small, the rewards will be more.

NerveNetwork generates 43,200 blocks per day, and each block initially generates 2 NVT rewards. (After the first block reward, the block reward will be reduced by 0.822% every 100 days).

To ensure the fairness, NerveNetwork will give the community users time to prepare. The first block reward will be generated at NerveNetwork block height 1,350,000.

Nerve’s main network nodes are divided into three tiers: Common nodes, consensus nodes, and virtual bank. Different tiers of nodes have different responsibilities in the network. Due to differences in responsibilities, the weights of the nodes is related to the node tier. Node weight influences reward amount.

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 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.

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.

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.

In addition to self-holding NVT to establish nodes, the best way is to establish its own mining pool (such as Wallet and Exchange) 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.

【AEX小凤仙】：用户如何参与质押Staking挖矿呢?

【Berzeck】：用户可将NVT进行质押以获得NVT收益，每次加入质押的最低数量为：1万 NVT。此外，质押期限越长，对应的权重越高。每位用户的总权重是根据质押数量和期限计算得出，用户的权重在全网总权重占比越高，收益就会越高。

除了质押NVT之外，用户还可选择质押不同类型的跨链资产，例如ETH和NULS。BTC、BNB、ERC20等其他跨链资产质押，会在后期陆续接通与开放。

质押不同类型的资产，其收益权重也有所不同。其中：NVT和NULS是其他跨链资产质押权重的2倍。

跨链资产质押的门槛等同于1万NVT的价值。比如：1NVT=1U，那么跨链资产质押需要价值10000U的资产才能质押。

【AEX Quera】：How to stake for rewards?

【Berzeck】：Users can stake NVT to obtain NVT rewards, and the minimum amount to stake each time is 10,000 NVT.In addition, the longer the staking period, the higher its corresponding weight.The total weight of each user is calculated based on the number and duration of the staking. The higher of user’s weightage as a percentage of the entire network, the higher the rewards.

Besides staking NVT, users can also stake different types of assets, such as ETH and NULS. The staking of other cross-chain assets such as BTC, BNB, ERC20, etc. will be also docked in the future. The weight of their reward is different for staking different types of assets. among them: the staking weight of NVT and NULS are twice of other cross-chain assets.

The minimum amount of cross chain assets staking is the equivalent of 10,000 NVT.

For example: 1NVT=1U, Then cross-chain assets requires worth 10,000 U to stake.

⑦

【AEX小凤仙】：NerveNetwork搭建了自己的DEX，可以简单介绍下NerveDEX吗？

【Berzeck】：NerveDex计划于8月上线，目前正在公测中。去中心化交易所是NerveNetwork打造DeFi的第一步，NerveNetwork在其底层架构中内嵌了去中心化交易所NerveDEX.

同时, NerveNetwork支持其他项目方或团队使用NerveNetwork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。NerveNetwork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。

【AEX Quera】：NerveNetwork has built its own DEX, can you briefly introduce NerveDEX?

【Berzeck】：NerveDex is scheduled to be online in August. and is currently in public beta. Decentralized exchange is NerveNetwork’s first step in creating DeFi. NerveNetwork has been embedded the decentralized exchange (NerveDEX) in its underlying architecture.

Meanwhile, it supports other projects or teams to use the NerveNetwork 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. NerveNetwork can better meet their needs for multi-asset management convenient ly and low-costly.

⑧

【AEX小凤仙】：NerveNetwork今年的发展计划有哪些呢？

【Berzeck】：7月10日，NerveNetwork主网已经上线发布；8月7日(也就是今日)，主网第二部分（包括主网节点、Staking等功能）上线了，支持普通节点、共识节点、虚拟银行的建立和用户参与质押挖矿。

NerveDEX、轻钱包计划于今年第三季度发布；同时，NerveNetwork将努力对接更多的区块链使用Nerve网络。在不久的将来，NerveNetwork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。

【AEX Quera】：what is the plan of NerveNetwork in 2020?

【Berzeck】：On July 10, NerveNetwork mainnet has been launched;

On August 7th ( today), the second part of the mainnet (including mainnet nodes, staking and other functions) was launched, supporting the establishment of ordinary nodes, consensus nodes, virtual banks and staking.

再次感谢Berzeck带来的精彩回答。本期AEX《看点直播间》就到此结束啦！Thanks again to Berzeck’s answer. Our AMA is near to the end.

Q3 2020：NerveDEX trading platform, light wallet will be available. After that NerveNetwork will continue docking more blockchains. In the near future, NerveNetwork 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.
