【TechWeb报道】2018年1月，经过长期的研发布局，恩兔科技透过N2家庭云盘与区块链技术的高配适性，宣布进军区块链产业，历经4个月的筹备，即日，恩兔科技发布了“分布式存储云区块链白皮书”。
[TechWeb Report] January 2018, after a long-term development of the layout, Enbu technology announced, through the high compatibility of N2 family cloud and block chain technology, its entry into the military block chain industry, which was prepared for four months, i.e., on the day of the launch of &ldquao; distributed white paper on the cloud block chain storage & rdquao;
下面将通过逐一解析白皮书的主要内容来详细阐述的技术点，主要分为以下8个方面：
The following technical points will be elaborated on a case-by-case basis by diagnosing the main elements of the White Paper, mainly in the following eight areas:
1. 恩兔科技采用了N2智能云盘作为基础存储节点的N2C分布式存储云，基于区块链技术构建的分布式存储云，能够有效的汇聚大量用户的闲置存储资源，并通过区块链、分布式文件系统、非对称加密算法、P2P网络协议等技术有效的构建成为一个安全、高效、稳定、可扩展的分布式存储网络，为去中心化的时代提供去中心化的存储能力。白皮书提出了N2C积分是对参与N2C共享云生态、共享闲置存储空间用户的一种奖励，并对其进行了系统介绍。
1. N2C distributed cloud storage using N2 smart cloud as a base storage node, distributed cloud based on block chain technology, capable of effectively bringing together the idle storage resources of a large number of users, effectively constructed through block chains, distributed file systems, asymmetric encryption algorithms, P2P network protocols, etc., into a secure, efficient, stable and scalable distributed storage network, providing decentralized storage capacity for the de-centralized era. The White Paper presents N2C credits as an incentive for participating in N2C shared cloud ecology, sharing idle storage space users and presenting them to the system.
2.恩兔科技利用区块链的不可更改性、去中心化的特点，区块链建立的记账体系有着高规格的信用保证。基于区块链技术构建的N2C分布式存储云，不同于传统的网络存储系统采用集中的存储服务器存放所有数据导致存储服务器成为系统性瓶颈的模式，而是利用大量的N2智能云盘作为基本的网络存储节点，将数据经过算法计算，分散存储在多台独立的网络节点上，利用海量存储设备分担负荷，利用位置服务器定位存储信息，提高系统的可靠性、可用性和存取效率，还易于扩展。
The Nrebret technology uses the immutable, decentralised character of the block chain, with a high-level credit guarantee for the accounting system established by the block chain. N2C distributed storage clouds based on block chain technology, unlike the traditional network storage system, which uses centralized storage servers to store all data in a pattern that makes storage servers a systemic bottleneck, but uses a large number of N2 smart cloud disks as basic network storage nodes to calculate the data mathematically, store them on multiple separate network nodes, share the load with bulk storage equipment, locate the stored information using the location server, improve the reliability, availability and efficiency of access to the system and also expand easily.
3.N2C分布式存储云通过N2智能云盘为用户提供安全可靠的云存储服务，在存储的基础上用户可对其拥有的原创内容进行共享，并提出积分打赏要求共享给其他用户。除此之外，由于采用了区块链和分布式存储技术，N2C还能够进行数字内容交易，为音视频等版权交易提供存储能力与可持续运作的交易平台。
3. In addition to the N2C distributed cloud storage, which provides users with a secure and reliable cloud storage service through the N2 smart cloud, on the basis of which users can share original content in their possession and offer credits for sharing to other users, N2C is also able to carry out digital content trading, providing storage capacity and a sustainable trading platform for copyright transactions, such as audio and video.
4.N2分布式存储云采用N2智能云盘作为基础节点，节点监控APP可进行基础的N2智能云盘存储操作，随时随地对自己的云盘进行监控及查看。
4. N2 distributed cloud storage uses the N2 smart cloud as the base node, which monitors the node on which the APP can base the N2 smart cloud storage operation and monitors and views its own cloud at any time or place.
目前，支持N2分布式存储云节点功能的产品型号为N1S(白色版本暂不支持)。
Currently, the product type that supports the N2 distributed cloud storage node function is N1S (white version not supported).
5.激励方式为：用户参与N2C分布式存储云空间，更多的共享闲置存储空间，N2C积分采用奖励机制，用户可通过如下方式获取N2C积分：加入N2分布式存储云生态，共享闲置的存储空间;通过上传数字作品到云共享平台，获得积分打赏;通过第三方平台兑换，获取积分。N2C积分可以用于兑换存储云的存储空间、生态平台内的应用服务及其他互联网服务等。N2C积分的奖励机制和用户提供的存储空间大小、在线时长、流量等因素成正比，通过创新性的PoS机制完成全网积分的公平分配。N2C独创的PoS算法将主要依赖三个主要参数：共享闲置存储空间总容量、上行带宽以及单位时间内的上行流量。
5. Incentives are: user participation in N2C distributed cloud storage space, more shared idle storage space, N2C credits using incentive mechanisms. Users can obtain N2C credits by joining N2 distributed cloud storage ecology, sharing idle storage space; receiving credits by uploading digital works to cloud-sharing platforms; and acquiring credits through third-party platform conversions. N2C credits can be used to exchange storage space for storage clouds, application services within ecological platforms and other Internet services. The N2C component incentives and users provide positive ratios for storage space sizes, online duration, traffic, etc., through innovative PoS mechanisms to achieve an equitable distribution of the full web content. The PoS calculation, which is uniquely created by N2C, will rely mainly on three main parameters: shared total spare space capacity, upper bandwidth and upflow over time.
6.在N2C独创的PoS算法中，每15分钟为一个证明期，系统对全网所有的设备统计以上三个数据，如果某台设备在这15分钟内离线时间超过2分钟，则在该时段内数据清零;积分每24小时分配一次，系统将24小时内每个节点在每个有效证明期获得的积分求和并写入区块。所以用户拿出来共享的存储容量越大、接入带宽越大，获得的N2C就会越多，以后可兑换的服务使用权就越多。与PoW、DPoS等算法相比，PoS算法耗电量低，是采用存储能力作为共识机制，拥有权益越大则成为下一个记账人的概率越大。而其他算法如PoW虽然算法简单，容易实现，但PoW算法缺点也非常明显，如浪费能源，区块确认时间难以缩短，新的区块链必须找到不同三列算法否则会面临比特币的算力攻击。
6. In a PoS algorithm that is unique to N2C, the greater the shared storage capacity of users, the greater the bandwidth, the more the N2C will be obtained, the more the convertible the use of the service will be. If a device has been offline for more than two minutes within that 15-minute period, the data will be zero within that period; the more likely it will be that each node will be divided and written into a block within 24 hours, the larger it will be by using storage capacity as a mechanism of consensus, the more likely it will be that the next accounter will have an interest. Other calculations, such as PoW, are simple and easy to achieve, but PoW calculations have a very obvious disadvantage, the more time it will take to identify the convertible services will be difficult to use.
7.N2C总发行数量为：10亿个，永不增发。自启动挖矿之日前6个月共发行20000万N2C积分，平均每日发行积分约为1098901，之后每6个月发行的积分在上6个月的基础上下降25%，例如，6-12月共发行15000万N2C积分，平均每日发行积分约为824176;12-18月共发行11250万N2C积分，平均每日发行积分约为618132;18-24月共发行8438万N2C积分，平均每日发行积分约为463599。
7. The total number of N2C issuances is: 1 billion, never increasing. A total of 20 million N2C credits have been issued six months before the start-up date, with an average of about 109,8901 per day, followed by a 25 per cent decline in the last six months in the next six months. For example, 150 million N2C credits were issued in June-December, with an average of approximately 82,4176 per day; 112.5 million N2C credits were issued in December-18, with an average of approximately 61,813.2 per day; and 8,438,000 N2C credits were issued in 18-24, with an average of approximately 46,3599 per day.
团队激励预留10000万N2C积分和投资者回馈预留5000万N2C积分锁定期一年，一年后解除锁定，每6个月最高可以释放总额的25%。5000万市场活动的预留N2C积分将用于不定期的市场活动回馈给共享云生态的参与者。
Team-incentives set aside 10 million N2C points and investors set aside 50 million N2C points for a fixed period of one year, with a locking down of up to 25 per cent of the total every six months. The 50 million N2C credits set aside for market activity will be used to provide feedback on occasional market activity to participants sharing cloud ecology.
8.关于星际文件系统即IPFS：N2C基于IPFS来构建可用性的分布式存储云系统，整体架构包括三个部分：会员系统、基于区块链的存储云平台、云生态服务。
8. With regard to the interstellar file system, IPFS: N2C, which is based on IPFS to construct accessible distributed cloud storage systems, the overall structure consists of three components: membership systems, storage cloud platforms based on block chains, and cloud ecological services.
星际文件系统(InterPlanetary File System，缩写 IPFS)是一个旨在创建持久且分布式存储和共享文件的网络传输协议。它是一种内容可寻址的对等超媒体分发协议。在IPFS网络中的节点将构成一个分布式文件系统。IPFS是一个对等的分布式文件系统，它尝试为所有计算设备连接同一个文件系统，提供了一个高吞吐量、按内容寻址的块存储模型，及与内容相关超链接。IPFS 从根本上改变了用户搜索的方式。通过 IPFS，用户搜索的是内容。按照这个设计，只有文件所有者可以判断这是否是用户要找的文件。此时，必须保证托管者不会通过移除文件或者关闭服务器而对文件做任何更改。当文件被添加到IPFS节点上，它得到一个新的名字。这个名字实际上是一个加密哈希，它是从文件内容中被计算出来。通过加密保证该哈希始终只表示该文件的内容。哪怕只在文件中修改一个比特的数据，哈希都会完全不同。当下一步向 IPFS 分布式网络询问哈希的时候，它通过使用一个分布式哈希表，可以快速(在一个拥有10,000,000个节点的网络中只需要20跳)地找到拥有数据的节点，从而检索该数据，并使用哈希验证这是否是正确的数据。N2C平台构建于IPFS系统之上，使用了IPFS的开源技术，但N2C构建的IPFS网络是独立运作的。或许在未来会考虑和IPFS主网进行互通。
The interstellar file system (InterPlatetary File System, IPFS) is a network transfer protocol designed to create permanent and distributed storage and sharing of files. It is a peer-to-peer distribution protocol for content. The nodes in the IPFS network will form a distributed file system. IPFS is a peer-to-peer distributed file system that attempts to connect all computing devices to the same file system, provides a high-absorption, block-to-content storage model with content location, and hyperlinks with content. The IPFS fundamentally alters the way the user searches. Through IPFS, the user searches the content. Only the owner can judge whether the document is the document that the user is looking for. In this case, the trustee will not make any changes to the document by removing the document or closing the server. When the document is added to the IPFS node, the name is taken into account when the data section of the network is used (the data section of the web, which needs to be used).
基于区块链技术的N2C分布式存储云，以有效的N2C积分激励邀请更多的N2智能云盘节点用户加入N2C分布式存储云共享平台，组建大规模的存储云生态圈。N2C分布式存储云将这些积聚的资源编织成一个可以信赖的自愈式存储网络，并通过复制和分散内容来实现健壮性，通过云计算的方式进行最优化的实时部署和利用，同时能够自动检测和修复故障，有效地帮助需求方节约成本。
N2C distributed cloud storage, based on block chain technology, provides an effective N2C component incentive to invite more N2 smart cloud node users to join the N2C distributed cloud-sharing platform and to form large-scale storage loops. The N2C distributed cloud has woven these accumulated resources into a trusted self-healing storage network, enabling robustness by copying and dispersing content, optimizing real-time deployment and utilization through cloud computing, while allowing automatic detection and repair of malfunctions and effectively helping to save costs on the demand side.
