Simplified The role of blockchain technology in the development of modern agriculture is to make agricultural products traceable, provide crops with insurance, directly promote the docking of production and sales, make agricultural transactions more convenient, and make agricultural finance more efficient. Zaipidian

1. Make agricultural products traceable: The most common use of blockchain in food and agricultural supply chains is to improve traceability. It enables companies to quickly trace unsafe produce to its source and where it was distributed. This prevents disease, saves lives and reduces the cost of product recalls.

C. What is the value of blockchain agriculture? What opportunities and development can blockchain bring to agriculture?

The value of blockchain lies in Security, the value of blockchain agriculture is for food safety, and these data play a very important reference role in the reproduction of agricultural products.
With the development of value-oriented agriculture, precision agriculture and centralized agricultural systems, this blockchain technology will promote the continuous development of the agricultural industry, and its technology can also bring more jobs.
Blockchain agriculture has already existed, but some areas are not mature enough, especially the traceability aspect. However, the launch of a Dmtc agricultural traceability project this year has filled this gap.
In terms of data collection, through the use of artificial intelligence and Internet of Things technology, it runs through the entire agricultural ecological chain. During agricultural production, the production environment data and production process data of agricultural products are fully automatically recorded. When agricultural products are transported, they are fully automatically recorded. For transportation data, DMTC terminals are connected to smart micromarkets during sales to collect consumption behavior data of product consumers. Through the popularization of smart micromarkets, terminals are spread throughout living communities, collecting rich data for industrial development.Progress, more complete value transmission and information transmission carrying the agricultural ecological chain

E. What disruptive changes will blockchain bring to traditional agriculture?

At present, there are two main directions for the combination of blockchain technology and agriculture: commercialization and Agricultural insurance

Judging from the current agricultural situation in our country, there are still many problems, such as from the form of agricultural production and management.Look, the current agricultural production and management are still relatively traditional and extensive, and the past situation of relying on the weather has not fundamentally changed; from the perspective of sustainable development of resources, domestic agriculture produces a large amount of resources in the production process and energy consumption, causing serious damage to the ecological environment and directly affecting the safety of the environment and ecology and the health of the people. From the perspective of informatization, the process of domestic agricultural informatization and modernization is still in its infancy. In the long term, more advanced technologies need to be introduced to enhance the intelligence level of the industry. Once blockchain technology matures enough, it will fundamentally change the current situation of agriculture and greatly promote the industrialization and modernization of agriculture.

F. How blockchain agriculture can make every link of agricultural products transparent and traceable

It can provide consumers with origin information and make people more assured.

G. What is the best way to operate agricultural technology with light assets

Six business models

1. Modern agricultural smart park

2. Blockchain Agriculture

Blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is Cryptographically guaranteed distributed ledger that cannot be tampered with or forged. Blockchain agriculture is to apply blockchain technology to the agricultural field to improve agricultural production and management.

3. Plant protection drones

Plant protection drones, also known as unmanned aerial vehicles, as the name suggests, are drones used for agricultural and forestry plant protection operations. This type of drone It consists of three parts: a flight platform (fixed wing, helicopter, multi-copter aircraft), navigation flight control, and spraying mechanism. Spraying operations are carried out through ground remote control or navigation flight control. Agents, seeds, powders, etc. can be sprayed.

4. Agricultural meteorological station

Agricultural meteorological station is a device that can automatically observe and store meteorological observation data. Its main function is to monitor wind in real time. , temperature, humidity, air pressure, grass temperature and other meteorological factors, as well as data changes in soil moisture content. Today, there are many types of automatic agricultural weather stations, but their structures are basically the same. They are mainly composed of sensors, collectors, system power supplies, communication interfaces and peripheral equipment.

5. Digital Rural Loan

In 2016, JD Finance pioneered and launched "Digital Rural Loan", which has three major characteristics. The first is to grant credit to farmers based on the quantitative model of agricultural production and farmers' historical production data, without mortgage or guarantee; the second is to accurately timely and quantitatively invest funds into the production process through the quantitative production model, allowing farmers toEvery cent of a citizen's loan does not incur idle fees; third, the system manages risks for farmers and assists in the informatization and automation of production management. "Under this model, many farmers who have no money to engage in large-scale breeding are able to achieve large-scale breeding. Through the order farming model, they are guaranteed to earn 3 yuan from raising a chicken, while the loan cost is only 6 cents. The cost-benefit ratio is completely acceptable.

6. Precision Agriculture

Precision agriculture, also known as Precision agriculture or Precision farming, was developed by researchers from the University of Minnesota in the United States. In the 1990s, soil scientists advocated the collective name of environmentally-sustainable agriculture.

The so-called precision agriculture refers to the precise and accurate adjustment of various fields according to the environmental conditions of each operating unit in the field and the spatiotemporal differences in crop yields. Plant agronomic measures to maximize the quantity, quality and timing of water, fertilizer, seeds, pesticides, etc., in order to obtain the highest yield and maximum economic benefits, while protecting the agricultural ecological environment and land and other agricultural natural resources.

Well, I have been to the Granary, which is based on blockchain technology, and then builds a network-wide blockchain technology, and then Liaocheng Collective

I. How does the application of blockchain technology in the agricultural field help?

What problems does blockchain solve in agriculture?
1. Traceability of agricultural products
Tracing of agricultural products has always been an important issue in agriculture. Pain point problem. Blockchain technology can make records non-tamperable, so there is detailed data from the production end of agricultural products to the circulation end and consumers, which can realize consumers’ clear consumption and increase consumers’ willingness to buy.< br />The traceability of agricultural products can improve the safety of agricultural products and food.
2. Information transparency
In addition to traceability in the agricultural field, there is also the problem of opacity in the information between producers and demanders.< br />Once blockchain technology is applied to agriculture, everyone can use big data analysis to establish credit rating references for growers and purchasers; use smart contracts to ensure fair transactions between growers and purchasers. At the same time, blockchain Chain technology can improve the contractual spirit between buyers and sellers of agricultural products.
In addition, with the emergence of blockchain in the food supply chain, this can simplify the process because the data management system integrates a series of brokers, farmers, processors The data management system has become more transparent, bringing dealers, distributors, regulators, retailers and consumers into its radar.
3. Reduce costs
After the application of blockchain technology, production, circulation, etc. 2 The cost of large links will be greatly reduced. For example, blockchain technology solves the automatic storage of information and database functions, thus reducing labor investment and investment in other facilities.
In addition, blockchain and applications realize everything The Internet helps manufacturers and distributors reduce various expenses. At the same time, the reduction of production and distribution costs will alsoLowering the price of agricultural products will ultimately benefit consumers.
Of course, in addition to the above three reasons, blockchain technology can also be applied in agricultural subsidies, land registration, etc. to solve problems such as corruption and rights and interests.
Therefore, the application of blockchain technology in the agricultural field has to be recognized by people at all levels.
The core advantage of blockchain technology is decentralization. It can achieve decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Point-to-point transactions, coordination and collaboration, thus providing solutions to the problems of high cost, low efficiency and insecure data storage common in centralized institutions.
The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. , which has had a relatively large impact on the domain name industry.
