IoT + Blockchain | IONChain: IOTA in China
The Internet of Things (IoT) is widely acknowledged as the third wave of the world information industry development, after the computer and internet. As the underlying foundation of the internet, Blockchain has certainly become one of the frontier technologies in the strategic layout of each country.
2018 will be a year when the Blockchain technology come to blossom and bear fruit, as well as a year when the IoT and the Blockchain collide closely, generate sparks and then set the prairie fire.
IOTA, a new type of digital cryptocurrency, focuses on solving the problems caused by M2M transaction and builds the blueprint of the future machine economic by realising a method of payment without transaction fee between machines.
Being same with IOTA serving the IoT, IONChain is a new type of basic platform of IoT based on the Blockchain and edge computing, aiming at achieving the unification of the security, flow, trading and criterion of IoT data and the access to IoT nodes of arbitrary type and scale.
Both of IONChain and IOTA are aimed at making up for the weakness of the IoT. What are the differences between them?
First, they are different in the architectures and algorithms.
IOTA is a technology for achieving transmission of distributed and irreversible information by using the DAG (directed acyclic graph, which is called Tangle in IOTA) to take the place of Blockchain. The function of cryptocurrency is integrated based on IOTA to serve the IoT. While the Tangle technology is not a real Blockchain but just solves the problem of the extension of Blockchain.
Therefore, as a technology, IOTA can be used in the Internet of things, but it could not be used as a kind of digital currency. This is also the reason why IOTA has no mining mechanism, nor miners, and why some people think that the Blockchain is just a cover for IOTA.
The IONChain advocates the concept of “one device, one coin, one code” wherein “device” refers to IoT device, “coin” refers to IONC, and “code” refers to the unique identification code of the IoT device connected to the IONChain network. The IONChain depends on the characteristics of edge computing, takes IPFS (Interplanetary file system) as a medium of data storage, and uses distributed architecture to effectively evade the potential safety hazards of centralized storage on the cloud, its favorable protection mechanism for privacy will also enormously enhance the involvement of individual IoT nodes.
ION protocol ID in the IONChain will endow the IoT nodes with a unique identity to make the data authentic and reliable, and the source traceable. At the same time, it will contribute to the accelerated formation of standards of the IoT industry. This is also the support of the vision of IONChain that “A Mining Machine for All Things” – all the IoT devices which have access to the IONChain can get mining rewards by an algorithm, and the owner of this device can be a big enterprise, small or medium-sized enterprises, and even a personal user.
Second, their application scenarios are different.
IOTA, a digital cryptocurrency, focuses on solving the problems caused by M2M transaction and builds the blueprint of the future machine economic by realizing a method of payment without transaction fee between machines.
Sending transactions over the IOTA network is a kind of pre-paid system, and once your transactions have been adequately validated from other people’s transactions, your transactions will be considered fully validated. The client of IOTA must perform minimal computation on two prior transactions in the network, and the work validation algorithm of IOTA optimizes the GPU. Therefore, in theory, the more transactions that occur on the network, the faster the transactions are confirmed, which has “unlimited scalability”.
However, due to the congestion problem, confirmation rate and confirmation time are often delayed, which seems to contradict “infinite scalability”. In addition, “no transaction fee” of IOTA are both a benefit and a pitfall, because it will bring a huge potential hazard of DOS attack that everyone can send a large number of transactions at any time to reduce the efficiency of the whole network, which is unacceptable in the real huge volume of IoT applications.
Unlike IOTA, IONChain is more than just a digital cryptocurrency designed to solve the problem of M2M transactions on IoT, but aims at resolving various problems about the security, flow, trading, and shares of IoT data to promote the common prosperity of the IoT ecological chain as well.
In the application of IoT, when cloud computing fails to develop in these fields, the edge computing scheme of IONChain will be a new solution. Based on the characteristics of edge computing, IONChain puts forward the concept of “A Mining Machine for All Things” and provides token ionic currency incentive for all IoT devices which have access to the IONChain.
The decentralised storage way of IONChain will bring disruptive applications to the security and privacy of IoT data. And compared with the traditional centralized network, it has many advantaged superiorities against external aggression and disaster, to the greatest degree achieving the data security and privacy protection.
On the premise of effective protection for privacy, the token incentives of “A Mining Machine for All Things” can also greatly promote the large, medium and small enterprises and individuals to participate in the IoT project, to speed up the development of the IoT facilities.
The concept “A Mining Machine for All Things” of IONChain, as well as series of IoT equipment, makes factories, enterprises, companies, shopping malls and residences closely connected with people’s daily life, thus giving birth to the new trading patterns of infinite possibility:
1. Traditional manufacturing enterprises can monitor the business status through the IONChain to see the upstream and downstream partners and terminal sales.
For instance, an African enterprise A set up a production line and found that the efficiency was not high and it needed to be optimized after running for a period. And through the data transaction platform of IONChain, enterprise A found that an east Asian enterprise B issued some sensor data and videos of a similar production line, and then obtained the configuration data and operating videos through IONChain to adjust the production line and improve the production efficiency greatly. At the same time, the cost of cross-regional and breaching the technical bulwark was largely reduced.
2. Companies and shopping malls can purchase personal data of IoT through the IONChain, analysing the personal preferences of consumers, shooting the arrow at the target to accomplish accurate marketing.
An Internet start-up, for example, wants access to personal information and routes of some car users for data analysis to do business. Through the ion-coin incentive mechanism, some car users voluntarily share their personal data through transactions. The company can quickly obtain the desired data scale and analyze materials through the data transaction of IONChain.
3. Individual users can use the IONChain for the sharing management of equipment using, earn ionic currency, and obtain further benefits.
For example, there is a business uptown owning large parking demand, some residents can install the intelligent lock, sign an intelligence contract of IONChain network with people who want to park, and park by automatically controlling the lock. After the transaction, the earnings will be automatically calculated and transfer to the account as the management incentive.
As the pioneer of the “Blockchain + IoT”, at present, the market value of IOTA has been more than 25 billion yuan, ranking tenth in the market of digital cryptocurrency, fully embodying that the vitality and potential of Blockchain technology in the field of IoT.
As the upstart of “Blockchain + IoT”, IONChain is also regarded as IOTA in China by many Blockchain investors and experts, indicating the strong momentum of IONChain.
The reason why investors and experts are so confident is that professional and reliable core team in addition to the concept and technology of IONChain.
Liu Tao, the founder of IONChain, CEO of Onechain, and the lecturer of the master course on Blockchain in Fudan University, finished MBA from EastChina Normal University. He is also the former CTO of ZHIWANG FINTECH and former senior director of Accenture, and has over 15 years of business consulting and technical architecture experience in high-techmanufacturing and financial industry. He is also a co-author of two books, “Practical Combat of Blockchain Development: Key Technology and Case Analysis of Ethereum”, “Practical Combat of Blockchain Development: Hyperledger Fabric Key Technology and Case Analysis”, mechanical industry press.
At present, the IONChain has recently got the strategic investment of capital by famous Blockchain investment organizations. It was planned to complete and launch the parent blockchain in August 2018. We all look forward to seeing the spark igniting the prairie fire of Blockchain + IoT!

物联网+区块链 | 离子链IONChain ：中国的IOTA
物联网被公认是继计算机、互联网之后，世界信息产业发展的第三次浪潮。而区块链做为互联网的底层基础，也当仁不让成为各个国家战略性布局的前沿技术之一。
2018年，将是区块链技术纷纷落地、开花结果的一年，也将是物联网与区块链亲密碰撞产生火花、继而燎原的一年。
提到服务于物联网的区块链技术，大家肯定会想到2017年的明星项目——IOTA。IOTA是为物联网而设计的一个革命性的新型交易结算和数据转移层，2017年12月实现了市值涨幅52000倍的华丽表演，让大家切身体会到了“区块链+物联网”的潜力和魅力。
IOTA是一种新型的数字加密货币，专注于解决机器与机器(M2M)之间的交易问题，通过实现机器与机器间无交易费的支付来构建未来机器经济的蓝图。
与IOTA同样服务于物联网，离子链（IONChain）是一种基于区块链和边缘计算的新型物联网基础平台，旨在实现物联网数据安全、流通、交易和标准的统一，实现任意规模、任意类型的物联网节点的接入。
IONChain和IOTA都是解决物联网的痛点问题，两者之间究竟有哪些不同呢？
首先，是两者架构和算法的不同。
IOTA宗旨是利用DAG（有向无环图，IOTA里叫做Tangle——缠结）代替区块链实现分布式、不可逆信息传递的一种技术，在此基础上集成加密货币功能，服务于物联网。而Tangle技术并不是真正的区块链，只是解决了区块链扩展问题。
所以IOTA作为一种技术可以在物联网中进行使用，但却不能作为一种Token进行使用。这也是为什么IOTA没有挖矿机制，也不存在矿工的原因，也是为什么部分人认为区块链只是IOTA的一个幌子的原因。
离子链倡导“一物一码一Token”的理念——“物”即物联网设备，“Token”即IONC，“码”即接入离子链网络中物联网设备的唯一识别码。离子链依托边缘计算的特性，以IPFS（星际文件系统）作为数据存储的媒介，利用分布式架构有效地规避云端集中存储的安全隐患，良好的隐私保护机制也将极大提升个人物联网节点的参与度。
而离子链中ION协议ID则会赋予物联网节点唯一身份，使得数据真实可信、来源可追，同时也助力于物联网行业标准的加速形成。这也是离子链“万物皆矿机”愿景的支撑——凡是接入离子链的物联网设备，都可以通过算法获得挖矿奖励，这个设备的拥有者可以是大企业、中小企业，甚至是个人用户。
其次，是两者应用场景的不同。
IOTA专注于解决物联网中，机器与机器（M2M）之间的交易问题，通过实现机器与机器间无交易费的支付来构建未来机器经济。
在IOTA网络上发送交易，是一种前付费类型的系统，一旦你的交易从别人的交易中获得了足够的确认，你的交易就会被视为完全确认。IOTA客户端必须在网络中的两个以前的事务上执行最低限度的计算，IOTA的工作验证算法是优化GPU的。所以从理论上讲，网络上发生的交易越多，交易得到确认的速度就越快，具有“无限可扩展性”。
不过由于拥堵问题，确认率和确认时间时常受到延误，这似乎与“无限可扩展性”是自相矛盾的。另外，IOTA的零交易费也既是福利又是隐患，因为交易费为0将带来巨大的DOS攻击隐患，任何人都可以在任何时刻发送大量交易来降低整个网络的效率，这在真正的巨大体量的物联网应用中是不可接受的。
与IOTA不同的是，离子链不仅仅只想解决物联网机器与机器之间交易的问题，更旨在解决物联网数据安全、流通、交易、共享上的诸多问题，促进物联网生态链的共同繁荣。
在物联网应用中，当云计算在这些领域一筹莫展时，离子链的边缘计算方案将是一个新的解决途径。依托边缘计算的特性，离子链提出“万物皆矿机”理念，对接入离子链的所有物联网设备进行token IONC激励。
离子链去中心化的存储方式将给物联网数据安全及隐私带来颠覆性的应用，并且在抵御外部攻击和灾害上相比传统中心化网络具有得天独厚的优势，能够最大程度的做到数据安全和隐私保护。
在隐私得到有效保护的前提下，“万物皆矿机”的token激励，又可以极大的促进大中小企业和个人加入到物联网项目中，加快物联网设施的发展。
离子链“万物皆矿机”的理念，串联的大量的物联网设备，将工厂、企业、公司、商场、住宅和人们的日常生活紧密联系在一起，从而孕育了无限可能的新兴交易模式：
1.传统生产制造型企业可以通过离子链监控业务状况，了解上下游伙伴和终端销售情况。
比如，某非洲企业A搭建了一条生产流水线，运行一段时间后发现效率不高，有待优化，通过离子链数据交易平台，企业A发现东亚某国企业B发布了同类流水线的传感器数据及生产线视频，通过离子链获取配置数据和操作视频对生产线进行调优，使生产效率大大提高，同时跨地域、突破技术壁垒的成本也大幅减少。
2.公司和商场可以通过离子链购买个人的物联网数据，分析消费者个人偏好，做到有的放矢，实现精准营销。
比如，某互联网初创公司希望获取汽车用户的个人信息及行车路线，用作数据分析以便开展相应业务。通过IONC激励机制，部分车主自愿通过交易分享个人数据。该公司通过离子链数据交易，即可快速获得期望的数据规模及分析素材 。
3.个人用户可以通过离子链进行设备使用的共享管理，赚取IONC，获得进一步的收益。
比如，某商务小区停车需求大，部分住户可以通过安装智能地锁，与停车人经过离子链网络的智能合约，自动控制地锁的开关进行停车，完成交易后收益自动计算并划转至其账户作为管理激励。
IOTA作为“区块链+物联网”的先行者，目前市值已超过250亿人民币，位列市场的第十位，充分体现了区块链技术在物联网领域的活力和潜力。
离子链作为“区块链+物联网”的新贵，也被很多区块链投资人和专家看好，称之为中国的IOTA，而除了离子链的理念和技术之外，专业靠谱的核心团队也是重要原因之一。
离子链创始人刘涛（八目观），旺链科技CEO，复旦大学区块链研究生课程主讲老师。华东师范大学MBA，原指旺金科CTO，原埃森哲高级总监，在高科技制造、金融行业有超过15年的业务咨询和技术架构经验。机械工业出版社《区块链开发实战：以太坊关键技术与案例分析》《区块链开发实战：Hyperledger Fabric关键技术与案例分析》两书合著作者。
目前，离子链（IONChain）已于近期获得了知名区块链投资机构了得资本的战略投资，并计划在2018年8月完成主链上线，让我们一起期待这把点燃区块链+物联网燎原之势的星星之火吧！
