That is, the recycling processes described in this specification all have to receive the supervision of the GRS certification authority; only if the authentication standard of the GRS authentication mechanism is met, the authentication of the GRS authentication mechanism can be passed. Regarding the GRS authentication procedure, it is a conventional manner for those skilled in the art, and is not described herein again.
It should be noted that, the official block chain node of the GRS authentication structure in this specification performs manual review on the uplink information in the recovery process, and after the review is passed, the service node performs signature by using its own private key.
And S104, the service node takes the first transaction certificate and the article information, the first signature and the article information as two pieces of data, and packages the two pieces of data into a first block, so that the first block is stored in a block chain after being identified by the block chain system.

A user can inquire the recovery process data of the whole process on the block chain, so that the user experience can be improved; and the method also better meets the supervision requirement.
At this time, the number of finished products to be sold and the number of finished products to be delivered from the factory should correspond one to one, and the corresponding relation is also stored in the block chain.
