Blockchain farm planting

1. The core demand of "blockchain farm" project is to ensure proction quality, ensure proction quality, realize fast and convenient circulation and improve farmers' real income. The practice of building blockchain farm through blockchain technology will bring value innovation in three aspects
the first is to establish a set of system standards for the proction of traceable procts, and use the combination of Internet of things, blockchain, intelligent manufacturing and other technologies to realize the traceability of the whole process and ensure that the grain is safe. The second is to establish an e-commerce platform with traceability attribute. Through the whole process of data value collection and activation, it not only realizes the real traceability of goods, but also increases the land output of blockchain farm by more than 1500 yuan per mu. Finally, the implementation of the blockchain farm will help the relevant parties of the instrial chain, such as blockchain, experts in the field of Internet of things, scientific research institutions and the government, to establish a good cooperation platform and communication mechanism
"at present, the first phase of research and development of the project has been completed. Within this year, we will use blockchain technology to trace the source and deliver the first batch of big farm grain to consumers. In the process of building a blockchain farm, how to link the data collected by massive IOT devices, how to integrate the blockchain technology with the current mature technology system and provide the same high quality of service, how to technically ensure the consistency between online and offline, and how to make the whole process without dead ends are the key points of project innovation. " Dong Ning, CEO of chainnova, said
in order to meet these challenges, chainnova has designed the platform infrastructure of "blockchain farm". Blockchain technology is at the bottom of the platform architecture of "blockchain farm", and embedded with real-time computing, big data processing, cognitive intelligence and other moles. In order to make users better understand the whole traceability history, data visualization innovation is also carried out on the basis of big data.

2. In short, blockchain technology is very helpful to the added value of goods in this scenario. There are several highlights: first, to solve the problem of trust, blockchain as a means of technological credit enhancement; second, Beidahuang's natural Internet of things foundation makes "machine trust" possible after + blockchain; third, electronic food stamps as digital assets circulate in the blockchain value Internet; fourth, demonstration cases of supply chain traceability and management, In a word, there is still a long way to go to make technology mature, which is an important step for Zhongnan group in its transformation, and for Beidahuang + Internet practice and win-win cooperation. In addition, Beidahuang and chain Nova also have certain cooperation.

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. By using blockchain, food companies can more quickly trace back to the source of food problems. This can not only help rece consumer risk, provide security, but also rece financial losses through targeted recall.

6. 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.

7. At present, the combination of blockchain and agriculture can be divided into two parts:
one is the traceability mode, which is commonly used nowadays. All agricultural activities, from planting to proction and sales, are recorded on the blockchain, so as to achieve the purpose of proct traceability. However, this method costs a lot, and usually has a special team or company to do it, Because the follow-up after-sales is very troublesome
the second is to use the form of blockchain token combined with the online mall to sell agricultural procts through the Internet. Instead of the usual cash, it uses the form of digital currency to circulate, which is equivalent to linking with the blockchain

8. For example, the vonetracer traceability system of wangchain technology can record the information of planting links from the purchase of seeds / fertilizers, sowing, irrigation, fertilization and other systems to the information records of picking and testing, and collect and monitor the whole process data according to different batch numbers, so as to realize the traceability management of planting link information.
