Speed up the application of block chain in the field of e-commerce of agricultural products

At present, the buyer's market in which the supply of domestic agricultural products exceeds the demand has emerged. "grow well and raise well, but also sell well and sell well at a good price, so that farmers can really get real benefits." in order to solve this problem, what should we do now? The author believes that it is of great practical significance to speed up the application of block chain in the field of agricultural product circulation.

Blockchain technology is the most attractive new technology this year.

Since the 1990s, China's information technology has experienced three major waves of computer, Internet and Internet of things, but it has encountered block segmentation resistance when it enters the "convergence of the three networks (new generation Internet, broadband telecommunications network, digital television network)". But the new generation of Internet has been closely integrated with the broadband telecommunications network, and then big data and cloud computing waves follow, and block chain technology has become a new wave in 2016.

Blockchain, a new technology, can be understood as a public accounting mechanism (technical solution), it is not a specific product. The basic idea is to ensure the authenticity and unusurability of the information by establishing a group of "public account books" on the Internet, in which all users in the network "keep accounts" and "audit". The blockchain has five characteristics:

One is decentralization: because the block chain depends on each node to maintain the system and ensure the authenticity of information transmission, based on distributed storage data, rather than a center for centralized management, each node can supervise spontaneously.

The second is de-trust: the establishment of a connection between any two nodes does not need to trust each other's identity, and the data exchange between the two parties does not need the basis of mutual trust, because all nodes in the network can act as "supervisors". So you don't have to worry about fraud.

Third, scalable: blockchain is an underlying open source technology, on this basis can achieve all kinds of expansion and de-centralization, de-trust applications, blocks can be expanded over time.

The fourth is anonymity: both sides of the data exchange can be anonymous, and the nodes in the network can exchange data without knowing each other's identity and personal information.

Fifth, it is safe and reliable: because the activities between any nodes are supervised by the whole network, and the database uses distributed storage. For hackers, first, it is impossible to disguise and carry out fraudulent activities, second, it is impossible to control the network only by capturing a node, and third, if a node is "hacked", it will be quickly restored because of the existence of other nodes.

Trustworthy joint incentive and untrustworthy joint punishment need blockchain technology.

On May 30th, the State Council issued the guidance on establishing and perfecting the Joint incentive system of honesty and Credit and accelerating the Construction of Social Integrity (Guofa (2016) No. 33). The block chain is the best technical form to implement the opinion.

It can turn single supervision into social co-governance, reduce the supervision pressure of the central government, and improve the effectiveness of effective supervision; it can reduce the contradictions of multi-sector supervision and really give full play to the role of social common supervision; it can achieve real connectivity and form a good ecological relationship; it can really implement the policy spirit of joint incentives and joint punishment for breaking promises.

Blockchain technology was produced in 2008, has been quite mature, and is widely used in the international community. In Hong Kong, China, it has been invested and managed as a public social resource. IBM has done a lot of research and development, and now it has entered the stage of 4.0. Tsinghua University and the Commodity Trading Market Circulation Branch of China things Union have reached an agreement to carry out a pilot project, and Hong Kong Tongyan has carried out block chain business of commodity trading in the mainland.

The Application path of Block chain in the Field of Agricultural products E-commerce in China

Block chain technology has been initially applied in the e-commerce of "three products and one standard" agricultural products, but this application has spontaneous factors, which need us to take the initiative to promote it.

On the one hand, the block chain can be applied to the circulation of "three products and one standard" high-quality agricultural products to avoid the production of 1.05 million tons of Wuchang rice, but the phenomenon of selling more than 10 million tons appears again.

On the other hand, the blockchain can be applied to the three key links of transaction, distribution and settlement in the circulation of high-quality agricultural products of "three products and one standard", such as:

The application of the block chain in the transaction link: the producer or seller A sends a transaction order to user B, and the transaction record is recorded in the "block" of the network, and the block transmits the transaction data to all members of the network to complete the transaction. The block is then added to the block chain, leaving a transaction record that cannot be modified and deleted, and each member verifies that the transaction is valid.

The application of the block chain in the material allocation link: the producer or seller A sends the material allocation instruction to user B, and the allocation record is recorded in the "block" of the network, and the block transmits the material allocation data to all members of the network to complete the allocation. The block is then added to the block chain, leaving unmodifiable and deleted material allocation records, and the physical allocation of each member is valid.

The application of the blockchain in the settlement link: the producer or seller A sends a settlement order to user B, and the settlement record is recorded in the "block" of the network, and the block transmits the settlement data to all members of the network to complete the settlement. The block is then added to the block chain, leaving an unmodifiable settlement record, and each member verifies that the settlement is valid.

In the case of demonstration and experience, popularize this new technology in the field of agricultural product circulation across the country and incorporate it into the planning of circulation infrastructure construction as a specific content.
