It should be noted that, in this specification, a blockchain node must be authenticated by the GRS authentication structure to have the functions of a recycle node, a plant node, and a sales node in this specification. 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.
At the moment, the article information is also packaged and enters the first block, so that the article information is conveniently checked. The method also comprises the step that the user verifies the private key signature of the service node, and the verification step comprises the following steps: a user acquires a public key of the service node through a client; the client verifies the first transaction certificate according to the service node public key to obtain article information; and if the verified article information is consistent with the article information, judging that the first transaction certificate is the service node signature.

In this example, the processing of the recycled items by the factory node often includes multiple processes. Taking a recycling bottle as an example, the recycling bottle needs to be recycled into polyester slices, then is processed into yarns by pre-oriented yarns POY, then is woven into gray cloth, then is dyed into finished fabrics, and finally is made into finished products such as raincoats, T-shirts, sun-protective clothes and the like. This description is only exemplary of two processing plants, a rough process and a fine process.
At this time, the article processing information comprises article rough processing information and article fine processing information, wherein the article rough processing information comprises a rough processing factory name, a semi-finished product name, semi-finished product time and a semi-finished product number; the article fine processing information comprises a fine processing factory name, a finished product timestamp and a finished product number.
In one example, the recycled article, the loss between before and after being roughly processed is a first loss; the loss between the roughly processed article before being finely processed and the finely processed article after being finely processed is a second loss; and the first loss and the second loss are within a preset loss range, so that a user can conveniently judge whether the article passes through the recycling process according to the preset loss range.
In the above example, the preset loss range, that is, the average loss range, is set, and different recycled items correspond to different loss ranges.
In one example, the method further comprises: the method comprises the steps that a sales node receives finished product sales information according to the operation of a sales user, wherein the finished product sales information comprises a sales network name, a finished product number and sales time; the sales node signs the finished product sales information by using a private key of the sales node to obtain a fourth signature; the sales node sends the fourth signature and the finished product sales information to the service node, and the service node signs the fourth signature and the finished product sales information by using a private key thereof to obtain a fourth transaction certificate; the sales nodes are block chain link points which are authenticated by a global recycling standard authentication mechanism; and the service node takes the fourth transaction certificate and the finished product sale information, the fourth signature and the finished product sale information as two pieces of data, and packages the two pieces of data into a fourth block, so that the fourth block is stored on the block chain after the consensus verification is completed by the block chain system.
In the specification, finished product sales information of the sales node is also subjected to chain storage, so that the whole article recycling process is traced to form a closed loop for article recycling. 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. That is, the number of the fourth transaction certificates corresponds to the number of the third transaction certificates one by one, one fourth transaction certificate corresponds to one third transaction certificate, one third transaction certificate corresponds to finished product delivery information, and one fourth transaction certificate corresponds to finished product sales information.
In one example, the number of the first transaction certificates corresponds to the number of the second transaction certificates, one second transaction certificate corresponds to one or more first transaction certificates, one first transaction certificate corresponds to one item information, and one second transaction certificate corresponds to one item processing information; or the number of the first transaction certificates corresponds to the number of the second transaction certificates, one first transaction certificate corresponds to one or more second transaction certificates, one first transaction certificate corresponds to one item information, and one second transaction certificate corresponds to one item processing information.
In this case, it is equivalent to one recycled article that, after being processed by the factory, can produce one or more finished products; it is also possible that a plurality of recycled items may be processed by the factory to produce a finished product. Both of these situations are encountered during recycling of the articles. The corresponding relation of the two conditions is stored on the block chain; such as: 10 bottles (500ml plastic bottles) correspond to one sun protection suit and one plastic bucket corresponds to 15 plastic bottles.
According to the method, the recovered articles are chained, a user can trace the recovery process of the recovered articles, and the user can improve the experience of recovering the articles and using the recovered articles by means of the anti-tampering and traceable functions of the block chain technology; and the GRS service node signature is convenient for monitoring the article recovery process.
