It can be understood that the distributed storage block chain system of the present solution is composed of product end nodes, and a public trust authority for block signature authentication performs signature authentication on a generated block, selects a block with the largest number of authentications as a common identification block, and then packs product data to form a current block for link storage, so that data chaining can be realized, and product information in each product end can be supervised according to the data, and can be queried in real time.
Wherein the candidate node generating the consensus block may be provided with an interest on a server side basis.
In practical applications, the product data may be collected based on a visual sensor installed at the product end, where the product data includes a product quantity and a product expiration date, and each product and the product expiration date of each product are located within a shooting range of the visual sensor.
It will be appreciated that the visual sensor needs to be able to capture the full look of the product, while also being able to capture the expiration date of the product, which is then packaged for storage. The visual sensor can be, for example, a camera and an image processor, the camera is used for collecting product pictures, and the image processor is used for processing the collected product pictures and acquiring the product quantity and the product expiration date.
And S102, the distributed storage block chain system stores the product information in a link mode.
It can be understood that after the product information is packaged to form the current block, all nodes link and store the current block and the previous block, so as to realize uplink storage of the product information.

correspondingly, the user side receives a private key of the product side for reading the product information, and the private key is sent by the distributed storage block chain system in response to the rights and interests of the user side.
Specifically, after querying the product information, the user needs to read the product information by using the private key, and therefore the user needs to obtain the private key from the blockchain system to read the product information.
Meanwhile, in order to encourage the product end to uplink the respective data in a packaging manner, the candidate nodes generating the consensus blocks can also be provided with rights and interests based on the service end.
