Starting with a complex agricultural scenario, six-domain chains attempt to give greater value to IoT data using blockchain


According to McKinsey, it is estimated that by 2025, the terminal of the Internet of things will reach 25 billion, and the direct market will reach 6 trillion U.S. dollars, bringing about 36 trillion U.S. dollars of related economy.
However, the prospects for the Internet of Things market, the actual landing slow. Dr. Shen Jie, Ph.D., Ph.D., researcher of the Chinese Academy of Sciences who works in Internet of Things, and Liu Ji block chain co-sponsor in the Internet of Things, believes that the information interaction between things and objects, things and people in the Internet of Things can not be trusted and the circulation process lacks Trust and data privacy protection, thus seriously affecting the value of data.

Recently, the six-domain chain initiated by his organization has merged with the "six-domain model" of IoT international, national standard and distributed block chain reference architecture standards. Taking full consideration of the technical characteristics of IoT and the requirements of commercial eco-construction, Block chain and optimize on the basis of the existing technology, trying to solve the IoT landing problems.

What is a six-domain model? Shen Jie introduced the traditional hierarchical architecture in the application of the Internet of Things has limitations in the development of the Internet of Things national standards and international standards and the long-term analysis and research on more than ten industry applications, and gradually formed a new form of Internet of Things The "six-domain model" reference architecture provides a top-level architecture for how to effectively deconstruct various important components of the IoT ecosystem for specific industry applications and how to establish business association logic.

Take the lead in testing agricultural and agricultural scenes

According to the recently published "Blue Book on China's Integration and Innovation of Blockchain and Internet of Things", the application of blockchain in the field of Internet of Things (IoT) has begun to explore around 2015. At present, a number of enterprises and institutions at home and abroad have invested in the blockchain Internet of Things applications, many of them well-known companies such as: Alibaba, Jingdong, ZTE, China Unicom, Universal, IBM, Cisco, Bosch, Toyota, Walmart, Siemens and so on. At present, there are some mature projects at home and abroad in areas such as intelligent manufacturing and supply chain management. Projects in other fields are mostly in the research and development stage.

Shen Jie believes that the six-domain model is refined through the study of the common model, but the correct or not but also in specific industries to verify that in promoting the process of landing, Shen Jie said that on the one hand, validated the rationality of six-domain model , On the other hand also confirmed its idea of the combination of blockchain and Internet of Things.

"We first landed from agriculture." Shen Jie cited a typical fish pond farming scene. "Most of the previous fisherman's farmed aquaculture experience may lead to fish deaths due to a variety of factors such as water quality changes, and the inclusion of the Internet of Things can help fish ponds to control water quality, monitor births, warnders, etc. At the same time, through the Internet of Things, we have obtained Farmers' production and transaction data. "

The problem is that the data that was originally of great value can not be properly utilized. Information asymmetry between farmers and banks, "Banks want to lend to farmers, peasants think the process cumbersome, more than 50,000 yuan will need to find someone to guarantee, so farmers prefer to credit intermediaries, resulting in production costs rose 15% -20% "

The data obtained through the Internet of things if it can be used by banks, as a reference for the user credit assessment, on the one hand to help banks provide better risk control conditions, assured lending, reduce the bad debt ratio, on the other hand to reduce peasant loans and production costs. Shen Jie said that with the Agricultural Bank of China, Nanxun Bank, farmers loans to achieve 300,000 yuan without the need for guarantees.

A Typical Case for the Integration of Blockchain and IoT in Agriculture

What is the role of blockchain? Shen Jie pointed out that such a typical scenario in early small-scale applications is very effective, but in the large-scale promotion process, can not guarantee the authenticity of the data and information in the process of circulation. With the blockchain, the key data of the core chain, banks, Internet of Things companies, farmers, insurance companies and other parties to jointly use the data on the blockchain. Blockchain, as a decentralized ecosystem operation platform, provides a guarantee for the construction of the credit system and value system of the Internet of Things.

In addition to the above scenario, the blockchain + IoT can be used in many fields such as insurance review and food traceability only in agriculture.

Internet of things help block the block landing

Shen Jie admitted that the development of the Internet of Things is still slow progress for many years, the lack of landing is not a technology or demand, "food safety, aging, environmental pollution problems and needs have always existed, the lack of how from a higher top-level perspective Conduct the framework, nested together to form a whole system of guidance.This is the six domain chain ideas.

In terms of teamwork, Dr. Shen Jie, the initiator of six domain chains, is the overall team leader of the National IOT Working Group for Basic Standards and has represented China in taking the lead in formulating the world's first IoT reference structure international standard ISO / IES30141; Professor Tsai Weide is a national " Distinguished Professor of the Program, and Director of the Blockchain Internet Laboratory at National Big Data (Guizhou) Comprehensive Experimental Zone. Donald Lawrence is a professor of computer science at UCLA and head of the Alan Turing Big Data Research Center. He was responsible for the research and development of the GoogleDeepMind project. At Citibank, , Bank of America and American Express and so on have served in more than manager positions.

In Shen Jie's opinion, many blockchain projects remain in the conceptual stage, with few landing.

"The most important role of the real social law currency is to promote the convenience of real life, but there is no good virtual goods corresponding to the virtual currency, so the virtual currency can only flow in the speculation.While the Internet of Things just to meet the block chain landing needs, Providing a concrete scene in the physical world for the arrival of the blockchain. "

At present, the six-domain chain team has reached a cooperation intention with Wisdom Agriculture (Qingyuntang, etc.), Wisdom Parking (Hui Tong Electronics, etc.) and Wisdom Health (Grace Valley Technology, etc.) and will push forward cooperation with ARM mbed IOT platform and block Cooperative development of chain integration. It is reported that six regional chain is expected to go online after six months.
