Description
Technical field
This application involves block chain technical fields, in particular to a kind of Internet of Things equipment, server and are based on block chain
Agricultural product source tracing method.
Background technique
In the continuous improvement with China's national life level, people especially pay close attention to the quality of diet, especially green
Color agricultural product receive the favor of the majority of consumers.But the good and bad jumbled together for agricultural product currently on the market, allows the true and false difficulty of consumer
It distinguishes.To solve this problem, agricultural product manufacturer is often through the anti-fake platform of tracing to the source of agricultural product is established in the prior art, by agriculture
Product place of production information etc. traces to the source information package as data packet, and has two dimensional code on agricultural product packaging, and consumer can pass through
Barcode scanning obtains these information.But in this case, manufacturer often can voluntarily distort information of tracing to the source, and data source is credible
Spend it is lower, be easy fascination consumer, can not really realize tracing to the source for agricultural product.
In order to further solve the above problems, block chain technology is applied in the retrospect of agricultural product.Block chain technology can
To promote the transparency and authenticity of merchandise news in supply chain, data can not be distorted and be traded can for taking precautions against false making of faking
It traces two big characteristics to combine, can solve the problems, such as that product flows through fake and forged in journey in supply chain to a certain extent.
When application block chain technology progress agricultural product are traced to the source, consumer again may be by the modes such as barcode scanning and obtain tracing to the source for agricultural product
Information, unlike, the data that information stores in block chain of tracing to the source, since there are block chain data can not distort
Advantage, can increase the confidence level for data of tracing to the source, to promote the degree of belief of consumer.But after block chain can only guarantee cochain
Data can not distort, and the data in agricultural product production process be by manually obtaining and uploading, therefore can not be from source
Data validity of tracing to the source is solved the problems, such as on head, consumer needs to be further improved the degree of belief for information of tracing to the source.
