AEX: Your Best Asset Guardian
Today’s our guest is Berzeck. He is founder of NerveNetwork, NULS Community Director & NTC Member. Welcome to our AMA, Berzeck! Please introduce yourself to our participates first.
【Berzeck】：Hello everyone, good afternoon! I am Berzeck, NULS NTC members and community councilor. I am graduated from the Military Engineering College of La Paz, Bolivia, with a bachelor’s degree in systems engineering. 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 mods 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.
【AEX Quera】：Thanks Berzeck! Well, our AMA is going on now.
【Berzeck】：NerveNetwork 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。NerveNetwork 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。
【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 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.
【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？
（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。
【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？
【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.
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）。
【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 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.
【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.
【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.
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.
