The Value of Blockchain Application
The structure of Blockchain big data transaction
The openness protocol. The interactive protocol and data format have
been made public by the system, and the participants can make the related
components join the system by self technology, ensuring the safety and controlled
for the data.
The open source code. The data access module has been written for the
participants by system, and the openness code can make users more clear,
proving the innocence of the system at the same time.
The whole system consists of three parts:
The public chain for exchange: common area in the main chain. The
operation has been constructed by the third party, building the foundation of
communication architecture to realize the connection between members and the
written of hidden protocols; Member authentication and access management;
Maintenance the public record chain to realize the record of index and
transaction; Set rules for the data and transaction to maintain the transaction
order; Assist parties to complete the traceability rights of data.
The member chain for exchange: member area in the side chain. The area
for parties data, storing the backup recorded data of common area, supervision
the correctness of Blockchain record from the common area; Maintain the private
data of the shared data, provide the query service; Initiate query, access to the
Node device. Connect the common area to member area, realize the
backup record from the common area, then complete the generation and submit
of the block chain and receive the message from the common area access to
communication terminal. According to the openness code, members can develop
by themselves and also can obtain the source code from the trading platform.
Blockchain for traceability
Food safety is one of the international livelihood projects called “popular project”,
which is directly related to people’s health and life safety, then related to the
economic development and social stability. In recent years, the food safety
incidents about pork, mutton fraud and pesticide residue on vegetables that will
increase the consumer concerns. So the food safety in China is an important
The food traceability can ease consumers’ anxiety and develop the safety
responsibility consciousness of food producers. The traceability system can
connect every sector like production, inspection, supervision and consumption,
then improve the degree of consumer confidence. At the same time, it can help to
find the cause of problems by analysis and tracking, prepare the measures ahead
of time to avoid the expansion of problems.
The current food traceability system is mainly based on the development
of enterprises, it can meet the traceability needs of enterprises but it is difficult to
achieve information sharing;
The chain of traceability is not long enough, so as to the information
transfer between the upstream with the enterprise, the product information is
difficult to be found in time, and impact the survey of food safety problems.
Due to the lack of credibility of the third party, consumers have doubts
about the traceability data, while the corporate enterprises have misgivings about
providing the operation data, resulting in the platform data in lack of accurate
verified and managed.
