@Tsuseven

Can you briefly tell us what “NuLink” means in 3-5 sentences?

您能用 3-5 句话简单地告诉我们“NuLink”是什么意思吗？

David Jiao :

NuLink network is a decentralized solution for privacy-preserving applications developers to implement best practices and best of breed security and privacy. The NuLink platform provides endpoint encryption and cryptographic access control. Sensitive user data can be securely shared from any user platform to cloud or decentralized storage and access to that data is granted automatically by policy in Proxy Re-Encryption or Attribute-Based Encryption. For the data user on the other side, Zero-Knowledge Proof can help them verify the data source. In more advanced privacy-preserving use cases, NuLink uses Fully Homomorphic Encryption to customize enterprise-level data computation services.

NuLink 网络是一种去中心化的解决方案，供隐私保护应用程序开发人员实施最佳实践和同类最佳的安全和隐私。 NuLink 平台提供端点加密和密码访问控制。敏感的用户数据可以从任何用户平台安全地共享到云或分散存储，并且通过代理重新加密或基于属性的加密中的策略自动授予对该数据的访问权限。对于另一端的数据用户，零知识证明可以帮助他们验证数据来源。在更高级的隐私保护用例中，NuLink 使用全同态加密来定制企业级数据计算服务。

@Tsuseven

Can you kindly explain homomorphic? ELI5 ?

你能解释一下同态加密吗？

David Jiao:

Yes, it's a cryptographic primitive for advanced data security application. Basically you can use for data manipulation in ciphertext space and even you can use it for machine learning trainning.

是的，它是高级数据安全应用程序的加密原语。基本上，您可以用于密文空间中的数据操作，甚至可以将其用于机器学习训练。

@Tsuseven

Very interesting- so what problem does NuLink try to solve and what are the solutions?

非常有趣——那么 NuLink 试图解决什么问题以及解决方案是什么？

David Jiao :

Nucypher implemented and improved the TFHE scheme using Python. Unfortunately, they gave up the project a few years ago. Maybe the reason is the efficiency of FHE in those years was always a bottleneck. However, in recent years, the efficiency and application of FHE have made breakthroughs, especially the programmable bootstrapping technology based on FHEW, TFHE is proposed and iterated constantly, which makes FHE landing soon. We will explore our solution using these latest technologies to ensure the availability of homomorphic encryption.

David Jiao :

Today, businesses across the spectrum understand that data is the key to maximize business value. Almost all businesses are mining data to fuel innovation and growth. Meanwhile data can cause irreparable damage to businesses, reputations and people’s lives if sensitive information leaks in a data breach. In many cases, even though the law requires companies to implement data protection (for example, Europe’s GDPR or General Data Protection Regulation that is known as the toughest privacy and security law in the world), businesses regardless of size – enterprise, small or medium businesses or startups – often find it difficult to protect their users’ data. Finding a solution to these data privacy problems is the motivation behind NuLink. By integrating best-in-class technologies we are building a strong technology foundation. The technical solutions provided by NuLink cover three main categories.

1.To ensure the availability of data in ciphertext form. The crypto techniques used here mainly include Zero Knowledge Proof.

2.Privacy-preserving data sharing. The general method is to encrypt data and let the data owner control access to it. The technologies include decentralized encrypted storage, proxy re-encryption, identity-based encryption and attribute-based encryption, etc.

3.Privacy-preserving data computing, which involves the integration of certain privacy computing capabilities into smart contracts. The technologies used include multi-party secure computing, homomorphic encryption and so on. These three kinds of technical solutions can provide privacy-preserving applications in many application fields.

Nucypher 使用 Python 实现并改进了 TFHE 方案。不幸的是，他们在几年前放弃了这个项目。可能是因为当年FHE的效率一直是瓶颈。但近年来，FHE的效率和应用都有了突破，尤其是基于FHEW的可编程自举技术，TFHE不断被提出和迭代，使得FHE很快落地。我们将使用这些最新技术探索我们的解决方案，以确保同态加密的可用性。创建至今，各行各业的企业都明白，数据是实现业务价值最大化的关键。几乎所有企业都在挖掘数据以推动创新和增长。同时，如果敏感信息因数据泄露而泄露，数据可能会对企业、声誉和人们的生活造成无法弥补的损害。在许多情况下，即使法律要求公司实施数据保护（例如，欧洲的 GDPR 或被称为世界上最严格的隐私和安全法的通用数据保护条例），但无论规模大小的企业——企业、中小型企业企业或初创公司 - 通常发现很难保护其用户的数据。寻找这些数据隐私问题的解决方案是 NuLink 背后的动机。通过集成一流的技术，我们正在建立强大的技术基础。 NuLink 提供的技术解决方案涵盖三大类。

1.保证密文形式数据的可用性。这里使用的加密技术主要包括零知识证明。

2.隐私保护数据共享。一般的方法是对数据进行加密，让数据所有者控制对它的访问。技术包括去中心化加密存储、代理重加密、基于身份的加密和基于属性的加密等。

3.隐私数据计算，涉及将某些隐私计算能力集成到智能合约中。使用的技术包括多方安全计算、同态加密等。这三种技术方案可以在很多应用领域提供隐私保护应用。

@Tsuseven

That's a big market- Can you describe some specific application scenarios using NuLink technology?

这是一个很大的市场——您能描述一些使用 NuLink 技术的具体应用场景吗？

David Jiao :

As I mentioned above, NuLink provides three kinds of technical solutions for many privacy-preserving scenes: encrypted NFTs trading market, secure electronic health records sharing, decentralized digital rights management, secure data sharing collected by IOT devices, financial encrypted data prediction, privacy-preserving social network, etc. One of the most exciting use scenarios for NuLink’s technology solution is in the encrypted non-fungible token (NFT) trading market. The NFT market is booming – in the first half of 2021, NFTs saw $2.5 billion in sales. This means there is a great opportunity for new solutions that take NFTs to the next level. At NuLink, our first objective will be to provide technology for NFT marketplaces to facilitate private auctions, encrypted and private collections, and entirely new exciting use cases for encrypted NFTs. For instance, the NuLink solution makes it possible for artists to set up secure online private auctions where potential buyers can virtually view and bid for the art pieces on sale. The artist could also create special viewing events for their most dedicated fans or special collectors. Similarly, NFT owners will be able to securely share access to a specific NFT or their private collection with whomever they desire and even charge a viewing fee.

正如我上面提到的，NuLink 为许多隐私保护场景提供了三种技术解决方案：加密的 NFTs 交易市场、安全的电子健康记录共享、去中心化的数字权限管理、物联网设备收集的安全数据共享、金融加密数据预测、隐私-保留社交网络等。

NuLink 技术解决方案最令人兴奋的使用场景之一是在加密的不可替代令牌 (NFT) 交易市场。 NFT 市场正在蓬勃发展——2021 年上半年，NFT 的销售额达到 25 亿美元。这意味着将 NFT 提升到新水平的新解决方案有很大的机会。在 NuLink，我们的首要目标是为 NFT 市场提供技术，以促进私人拍卖、加密和私人收藏，以及全新的令人兴奋的加密 NFT 用例。例如，NuLink 解决方案使艺术家可以建立安全的在线私人拍卖，潜在买家可以在其中虚拟查看和竞标出售的艺术品。艺术家还可以为他们最忠实的粉丝或特别收藏家特别的观看活动。同样，NFT 所有者将能够与他们想要的任何人安全地共享对特定 NFT 或其私人收藏的访问权限，甚至收取观看费。

@Tsuseven：

Very cool, I didn't think encrypted NFTs were a thing.

Does NuLink have a token and what is it used for?

非常酷，我不认为加密 NFT 是一回事。

NuLink 有令牌吗？它的用途是什么？

David Jiao:

NuLink’s token symbol is NLK. The total supply of NLK is 1 billion and it will be generated in two stages: pre-allocation and stake mining after the mainnet launch.The pre-allocation of NLK can be classified into four categories: Foundation (15%), BD & Community Incentivization (20%), Core Team Incentivization (15%) and Pre-sale (20%). After the mainnet is launched, the remaining 30% of the total supply will be mined by Providers in the NuLink network within four years. After four years, the new mining rules will be determined by the on-chain governance mechanism (DAO) maintained by the community. In the NuLink network, NLK tokens have the following main functions. They will be: 1. Used as the staking collateral for different kinds of Providers (Proxies, Watchers, Computing Providers, Storage Providers). Providers need to stake NLKs in the NuLink network to provide services and obtain benefits. Meanwhile, they will bear the risk of NLK slashing in the case of a penalty. 2. Used as the staking benefits for different kinds of Providers (Proxies, Watchers, Computing Providers, Storage Providers). If the Providers provide proper services in the NuLink network, they will be rewarded with NLKs. 3. Used as the NuLink network’s service fees. Users in NuLink who want to use the service (secure data storage, secure data sharing or secure data computing) need to pay fees to the corresponding providers. 4. Used in the election and voting of the on-chain governance mechanism (DAO). NLK is used to vote on proposals.

American DREAM joined the group.

1. 用作不同类型提供商（代理、观察者、计算提供商、存储提供商）的抵押品。提供商需要在 NuLink 网络中质押 NLK，以提供服务并获得收益。同时，他们将承担NLK被罚下的风险。

2. 用作不同类型提供者（代理、观察者、计算提供者、存储提供者）的权益。如果提供商在 NuLink 网络中提供适当的服务，他们将获得 NLK 奖励。

3.用作NuLink网络的服务费。 NuLink 中的用户想要使用该服务（安全数据存储、安全数据共享或安全数据计算）需要向相应的提供商支付费用。

4. 用于链上治理机制（DAO）的选举和投票。 NLK 用于对提案进行投票。

@Tsuseven：

That all looks great- Can you briefly describe the architecture of NuLink?

一切看起来都很棒——你能简要描述一下 NuLink 的架构吗？

David Jiao :

The NuLink network integrates the Application Layer, the Cryptograph Layer, the Storage Layer, the Blockchain Layer and the Watcher Network:

1. The Application Layer: The Application Layer is an abstract interface layer that directly interacts with the application. The Application Layer also needs to interact with the Cryptograph Layer to grant authorization of the application’s privacy data.

2. The Cryptograph Layer: The Cryptograph Layer is an entity that handles cryptographic operations on behalf of the Application Layer. The cryptographic operations include key generation, encryption, decryption, etc. The Cryptograph Layer also needs to connect to the Storage Layer and is responsible for uploading and downloading the encrypted privacy data. 3. The Storage Layer: The Storage Layer is a storage network that can be used to store encrypted privacy data. Currently, we support IPFS (InterPlanetary File System) as our decentralized storage network. Other storage networks such as Swarm and S3 will be available soon.

4. The Blockchain Layer: The Blockchain Layer is the blockchain system that can handle the proxy registration and re-encryption request management. Currently, proxies can register in Ethereum only. However, the user could send their requests to other blockchain systems such as Polkadot and Solana.

5. The Watcher Network: The Watcher Network is a relayer network that relays the information of proxy nodes from Ethereum to other blockchain systems. The Watcher Network will be maintained under an on-chain governance mechanism (DAO) to guarantee its decentralization and security.

NuLink 网络集成了应用层、密码层、存储层、区块链层和观察者网络：

1. 应用层：应用层是与应用直接交互的抽象接口层。应用层还需要与密码层交互以授予应用程序隐私数据的授权。

2. 密码层：密码层是代表应用层处理密码操作的实体。密码操作包括密钥生成、加密、解密等，密码层还需要连接存储层，负责上传和下载加密的隐私数据。

3.存储层：存储层是一个存储网络，可用于存储加密的隐私数据。目前，我们支持 IPFS（星际文件系统）作为我们的去中心化存储网络。其他存储网络如 Swarm 和 S3 将很快可用。

4. 区块链层：区块链层是可以处理代理注册和重加密请求管理的区块链系统。目前，代理只能在以太坊中注册。但是，用户可以将他们的请求发送到其他区块链系统，例如 Polkadot 和 Solana。

5. 观察者网络：观察者网络是一个中继网络，将代理节点的信息从以太坊中继到其他区块链系统。观察者网络将在链上治理机制（DAO）下进行维护，以保证其去中心化和安全性。那高于我的工资等级, 但只要它有效.

@Tsuseven：

Can you explain the relationship between NuLink and NuCypher?

您能解释一下 NuLink 和 NuCypher 之间的关系吗？

David Jiao :

NuLink is an independent privacy project. It got official support from NuCypher when the project started. Our team cooperates with the NuCypher team both in Technology and Business Development. Here I want to cite a comment from Maclane(The Co-founder of NuCypher) to explain the difference between NuCypher and NuLink. "I'm excited to see NuLink bring NuCypher/Threshold's proxy re-encryption and other privacy-preserving technologies to smart contract platforms beyond Ethereum. Cross-chain interoperability is both one of the hardest technical problems and alluring siren calls in the blockchain space. The NuLink team is well-positioned to execute on making this dream a reality and I'm happy to support them in that quest."

NuLink 是一个独立的隐私项目。项目启动时得到了 NuCypher 的官方支持。我们的团队在技术和业务开发方面与 NuCypher 团队合作。这里我想引用 Maclane（NuCypher 的联合创始人）的评论来解释 NuCypher 和 NuLink 的区别。 “我很高兴看到 NuLink 将 NuCypher/Threshold 的代理重新加密和其他隐私保护技术带入以太坊以外的智能合约平台。跨链互操作性既是区块链领域最困难的技术问题之一，也是诱人的警报。 NuLink 团队已经做好了让这个梦想成为现实的准备，我很高兴在这个任务中支持他们。”

@Tsuseven：

Blackcofy:

Good morning, sir. I see you have done a lot of AMA. My question is, what do you want from so many AMA and what is your goal for the community? Do you think the community is the basic role in the project?

早上好先生，我看到你做了很多 AMA，我的问题是，你希望从这么多 AMA 中得到什么，你对小区的目标是什么？您认为小区是项目中的基本角色吗？

David Jiao :

Community is always a very fundamental role for any project. With it, you can easy prove what you have been done is meeting the public's expectation. The community we are trying to build for our project will be a techy, nerdy, constructive community for a long term commitment and excitment.

对于任何项目来说，社区始终是一个非常基本的角色。有了它，你可以很容易地证明你所做的是满足公众的期望。我们试图为我们的项目建立的社区将是一个技术性，书，建设性的社区，以获得长期的承诺和兴奋。

Jude NOOD Paige:

What are plans in for global expansion? Are you focusing on market at this time or focus on building and developing or getting customers and users, or partnerships?

全球扩张的计划是什么？您此时是专注于市场还是专注于建立和开发或获取客户和用户，或合作伙伴关系？

David Jiao :

We are facing global market for sure. First of all. it's a international team with all kinds of industrial backgrounds. We are discussing with a lot of potiential cunstomers from EU, US, China. On Chain or Off Chain business. Building products, customize it with a super agile way for special early customers, we are trying to use this partnership for many business. Keep follow our website, you will see updates every second week about our partnership.

我们肯定会面对全球市场。首先。这是一支具有各种行业背景的国际化团队。我们正在与来自欧盟、美国和中国的许多潜在客户进行讨论。链上或链下业务。为特殊的早期客户构建产品，以超级敏捷的方式对其进行定制，我们正在尝试将这种伙伴关系用于许多业务。继续关注我们的网站，您将每两周看到一次关于我们合作伙伴关系的更新。

Jude NOOD Paige:

Security is the most important thing to consider want starting up a project, how secured is this project for users and investors?

启动一个项目时，安全性是最重要的考虑因素，这个项目对用户和投资者的安全性如何？

David Jiao :

Endpoint encryption, decentalized storage, 3000 active nodes with KMS. That's some keywords of technologies we are trying to use for data security. But for real business we are discussing with our customers, they have more requirements than just fully secured data. For example, the network reliability, the performances, etc. So we have to be a very professional product team to fulfill all of them to get the project done. It's tough but it's also our strength compared to other pure crypto project.

端点加密、去中心化存储、3000 个带 KMS 的活动节点。这是我们试图用于数据安全的一些技术关键词。但是对于我们正在与客户讨论的实际业务，他们的要求不仅仅是完全安全的数据。比如网络的可靠性，性能等等。所以我们必须是一个非常专业的产品团队来完成所有这些才能完成项目。这很艰难，但与其他纯加密项目相比，这也是我们的优势。
