Application of agricultural blockchain

1. The application of blockchain in the field of agriculture is developing day by day. Jiminsheng connects the front, back, left and right blocks of "things" into a chain with one technology, but the original data of each block can not be tampered with. It is a technology of "each mole chain" in the field of Internet of things that can be trusted by participants.

2.

A: first, the connotation of blockchain

blockchain is a distributed shared ledger and database, which is decentralized, tamper proof, traceable, collective maintenance, open and transparent

Agricultural traceability is the most complex and difficult part of food traceability. At present, there is no complete agricultural proct traceability system based on food safety proction and whole process supply chain management

2. The most important part of the construction of agricultural traceability system is "one center and three moles", which is a traceability cloud data center and three moles of procers, regulators and consumers

Third, composition of blockchain

blockchain system is composed of data layer, network layer, consensus layer, incentive layer, contract layer and application layer

4. The decentralization of blockchain will greatly rece the cost of Internet maintenance and enhance the intelligent and large-scale level of Agricultural Internet of things. At the same time, the agricultural procts traceability system based on blockchain technology solves the trust crisis of consumers for procts, and makes people's dining tables healthier and safer
in the field of agriculture, what are the trends of blockchain agriculture
1. Internet of things + UAV + blockchain
logistics ensures the interconnection of everything, UAV provides proction management services, and blockchain provides recording and traceability technologies. It will be concive to the development of precision agriculture, rece pesticide investment and improve the quality of agricultural procts
2. Blockchain + data + artificial intelligence
the application of blockchain in agriculture can eliminate information asymmetry to the greatest extent, improve the information transparency and timely response ability of the whole instrial chain, and realize the value-added of the whole instry
the integrated development of blockchain + data + artificial intelligence can maximize the value of agricultural big data and rece the input cost< In early February, the Chinese government issued "guidance on the revitalization of rural financial services". The new framework proposed this time is part of the financial service efficiency improvement plan in the National Rural Revitalization Plan
blockchain + agricultural finance will provide a convenient way for small farmers' loans and bring authenticity and predictability to the credit investigation of agricultural financial institutions
4. Blockchain + rural logistics
e to the small distribution of rural logistics, package loss and difficulty of agricultural procts ascending are caused. But blockchain technology can solve these problems
5. Blockchain + agricultural supply chain
this kind of application is the reason why major shopping malls graft blockchain. For example, Wal Mart, Carrefour and other large supermarkets bring the whole fresh food and food supply chain into the block chain management, so as to rece costs and improve proct safety. At present, Cargill, an American agricultural giant, is vigorously developing the application of blockchain + agricultural supply chain finance
in addition to agriculture, the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

5. From 2009 to now, blockchain technology has developed from blockchain 1.0 era to blockchain 3.0 era, from the special technology of digital currency to the open technology of social field. With the promotion of the 13th five year plan for national informatization and the national big data strategy, the deep integration of blockchain and real economy is becoming the general trend
as China's agricultural instry has been facing many problems such as highly dispersed operators and long instrial chain, there are many obstacles on the road of transformation and upgrading. The blockchain has the point-to-point trust under the distributed cooperation, and the tamperable records can just solve many pain points in the uplink of agricultural procts, eliminate the information asymmetry to the greatest extent, improve the information transparency and timely response ability of the whole instrial chain, and realize the value-added of the whole instry. Therefore, blockchain technology is entering the field of agricultural procts proction and circulation, and is profoundly transforming China's agriculture
recently, China's first white paper on agricultural blockchain was released by China rural network. Through analyzing the actual case of China rural network's efficient integration of proction end and sales end by using Internet of things and blockchain technology, it is confirmed that the application of blockchain in agricultural instry is not simply to make the traditional offline process online, but to empower and enhance the efficiency of the instry
SUN Wei, CEO of China rural power grid, interprets the methodology of blockchain
as a representative enterprise of B2B e-commerce of agricultural procts in China, the core transaction category of China rural power grid is silk, with an annual transaction volume of several billion yuan. However, the upstream proction monomer of silk instry is small and scattered, the instrial chain is long and inefficient, the transaction cost is too high, and the buyer and seller will often break the contract artificially
China rural power grid blockchain + cocoon and silk instry supply chain
through blockchain Distributed Accounting and tamper proof technology, China rural power grid can present the information of buyers and sellers to upstream and downstream parties and relevant third parties openly and transparently, and the defaulter will be abandoned by the instry, thus establishing a positive reputation ecology through mutual chain, and letting good currency drive out bad currency
at present, the agricultural blockchain platform of China rural power grid has achieved success in the first stage, which can not only reshape the trust relationship between all parties, but also significantly improve the transaction efficiency and rece the transaction cost
generally speaking, the instry generally believes that blockchain will be used in the Internet of things, agricultural procts traceability, rural finance and other six fields
1 Internet of things
the combination of Internet of things and blockchain will enable Internet of things devices to achieve self-management and maintenance, saving the high maintenance cost of cloud control as the center
2 big data
blockchain technology has point-to-point trust, and tamperable records will become an excellent way to solve the problem of data authenticity and effectiveness
3 quality and safety traceability
the agricultural procts traceability system based on blockchain technology, all data can not be tampered with, making the information more transparent, true and accurate
4 rural finance
the open and tamperable nature of blockchain technology makes it possible for decentralized trust mechanism. When applying for loans, it is no longer dependent on banks, credit reference companies and other intermediary institutions to provide credit certificates. The lending institutions can obtain the corresponding information data of the blockchain
5 agricultural insurance
blockchain technology can improve the protection of agricultural intellectual property rights and the transaction of agricultural property rights, and greatly simplify the process of agricultural insurance. At the same time, smart contract will also make agricultural insurance payment more intelligent
6 supply chain
e to the openness and transparency of data among all parties, a complete and smooth information flow is formed in the whole supply chain, which helps to improve the efficiency of supply chain management. The characteristics of non tampering data and transaction traceability can also eliminate the problem of fake and inferior procts in the process of proct circulation in the supply chain
in fact, some powerful agricultural enterprises have been aware of the opportunities of blockchain and have made an early layout to explore.

6. The value of blockchain lies in safety, and the value of blockchain agriculture is for food safety, and these data have a very important reference role for the reproction of agricultural procts
with the development of value oriented agriculture, precision agriculture and central agricultural system, this kind of blockchain technology will promote the continuous development of the agricultural instry, and its technology can also bring more jobs
blockchain agriculture has existed for a long time, but some places are not mature enough, especially traceability. However, a dmtc agricultural traceability project was launched this year to fill the gap
in terms of data collection, through the application of artificial intelligence and Internet of things technology, it runs through the whole agricultural ecological chain. During agricultural proction, it automatically records the proction environment data and proction process data of agricultural procts, when agricultural procts are transported, it automatically records the transportation data, and when selling, dmtc terminal connects with intelligent micro supermarket to collect consumer behavior data, Through the popularization of intelligent micro supermarket, terminals are all over the living quarters, collecting rich data for instrial development, and carrying the value transmission and information transmission of agricultural ecological chain more perfectly
