Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a supply chain tracing method based on a block chain, including:
s101, determining a blockchain platform which is created based on a blockchain framework in advance, wherein the blockchain platform comprises a main chain and a side chain, and nodes in the blockchain platform comprise a supply mechanism, a production mechanism, a sales mechanism, a supervision mechanism and a consumer.
The Blockchain (Blockchain) is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like, and is essentially a decentralized database.
A blockchain platform created based on the blockchain framework may first be determined. The blockchain frame may be any blockchain frame capable of implementing the corresponding function of the embodiment of the present application, for example, bitcoin, etherhouse, Fabric, Corda, and the like. A blockchain platform may refer to a platform that stores a blockchain, e.g., may be a distributed system, etc. Of course, the blockchain platform may also directly represent the blockchain itself, and is not limited herein.
The blockchain platform includes a main chain and side chains, and the side chain (Sidechain) technology can be applied to the expansion of blockchains, and is a protocol that can allow data in blockchains (which may be referred to as main chains herein) to be safely transferred to other blockchains (which may be referred to as side chains herein) and also can be safely returned to the main chain from other blockchains. The protocol transfers some frequent and small transactions to the side chain for carrying out, thereby not only improving the operation efficiency of the block chain platform, but also reducing the transaction fee. Of course, in the block chain platform, there may be only one or more side chains, which correspond to different enterprises and are not described herein again.
As shown in fig. 4, each process corresponding to a product includes a supply mechanism for supplying raw materials, a production mechanism for producing processed products, a sales mechanism for selling products, and a corresponding regulatory mechanism. These mechanisms can be deployed as nodes in a blockchain platform. Of course, consumers may also be deployed in the blockchain platform as nodes, which are not described herein.
S102, determining raw material data of raw materials supplied by the supply mechanism, production data when the production mechanism produces processed products, sales data of products sold by the sales mechanism, and supervision data of the supervision mechanism for the products.
After the blockchain platform is determined, data corresponding to the corresponding mechanism of the product in the production process can be determined, the data can be provided by the mechanism, and the data can comprise raw material data of raw materials supplied by a supply mechanism, production data when the production mechanism produces processed products, and sales data of the products sold by a sales mechanism.
The raw material data may include the origin, quality, specification, etc. of the raw material, and the sales data may include relevant data of the sales organization at the time of selling the product, such as sales volume, profit, vendor, consumer, etc.
The production data may be data used directly during the production process or other data that can indirectly direct the production to proceed or follow-up production improvements. The production data for example comprises at least one of: enterprise qualification, standard statement, production process, product certification, production flow data and the like. In addition to the enterprise itself, other parties involved in the production of the product (e.g., foundry manufacturers, third party integrators, etc.) may also provide production data of the product to the platform under the authorization of the enterprise. For ease of description, the enterprise itself and these other parties are collectively referred to as a production facility.
The production process comprises, for example, the steps of describing the origin and vein of the product, the processing links and equipment to be passed from the raw material to the finished product, and the symbols indicating the key control points of each link, even the specific process parameters of the product. The production process may be predetermined before production, and may be different from the actual production process.
The manufacturing process is preferably a relatively broad and practical process and may generally comprise at least most of the actual process stages from the time the product is in a raw material state until the time the product is introduced and used by the consumer. Such as which production lines are actually experienced, who the responsible person is, which warehouse manager's access operations are attended, which dealers are attended, etc.
The production process data may include, for example, data for at least one of the following production process phases: an idea stage, a design stage, a research and development stage, a manufacturing stage, a marketing stage, a warehousing stage, a delivery stage, etc. The member information, generation information and production information (such as drawing, code, document and mould) information of the stages can be used as the production flow data. The production flow data can be submitted to the platform by the corresponding stage of the manager, or the production flow data can be submitted through a uniform channel after the enterprise integrates the production flow data inside the platform, and other production data can be processed similarly. The submission of the production data can be realized by scanning corresponding scanned quality codes or quality code two-dimensional codes through scanning equipment such as a smart phone, a Personal Digital Assistant (PDA) scanning gun, a point of sale (POS) machine and the like.
Since the production data of the product is provided by the production organization, the data may be in the suspicion of beautifying, and in order to obtain more fair and objective quality data, the platform can also collect the relevant data of the product from the supervision organization supervising the product and the consumer of the product.
Generally, regulatory bodies such as governments, regulatory bodies, detection bodies, etc. can be considered more objective and fair, and more reliable, for the supervision of products. For a part of production data (for example, enterprise qualification, enterprise registration information, product production permission, etc.), which is in the state or industry mandatory regulations, production organizations report at these regulatory organizations, and then the reported part of production data can also be provided to the blockchain platform by these regulatory organizations, so that it is more reliable.
In addition to the backup data, the supervision data may include, for example, government test data, sampling data of a supervision department, test condition reports of a test institution, and the like. The regulatory data may be specific to the target enterprise or its products, such as detecting hardware conditions in the target enterprise's manufacturing plant, spot-checking product sample quality, etc.
Of course, the production data may also include more kinds of data, such as audit data reflecting whether the product is sold in different areas or not, competitive product data on the market, imitation data on the market, and the like, which are not described herein again.
S103, writing the raw material data, the production data, the sales data and the supervision data into the side chain, and writing hash values corresponding to the raw material data, the production data, the sales data and the supervision data into the main chain.
As shown in fig. 3, after the corresponding data is determined, the data may be written into the side chains of the blockchain platform and then the corresponding hash value is written into the main chain. Corresponding data are stored in the side chain, and only the corresponding hash value is stored in the main chain, so that a series of problems caused by excessive data in the block chain are solved. Once the consumer purchases fake and shoddy products, the problem can be determined by tracing the source at any time, and the rights and interests of the consumer can be maintained.
In addition, corresponding intelligent contracts can be generated in advance and deployed in the blockchain platform. The intelligent contract includes at least one of raw material data, production data, sales data, regulatory data. The intelligent contract is used for writing raw material data, production data, sales data and supervision data into the side chain; or calculating to obtain hash values corresponding to the material data, the production data, the sales data and the supervision data; or writing the hash values corresponding to the raw material data, the production data, the sales data and the supervision data into the main chain. Since the intelligent contracts on the blockchain platform are public, each node can check whether the intelligent contracts are in accordance with the preset agreement or not and deploy the intelligent contracts on the own node. The consumer can inquire the intelligent contract through a corresponding way, so that the degree of automation of the transaction is improved, and the trust degree of the consumer is further increased. The intelligent contract can only be changed in an upgrading mode, each node needs to be synchronously deployed, once the intelligent contract is deployed, the intelligent contract can only be executed through a program, interference of human factors is avoided, and the reliability of data is enhanced.
In one embodiment, the side chain is a federation chain, and the consensus nodes in the side chain include a number of facilities predetermined among a supply facility, a production facility, a sales facility, and a regulatory facility. The side chain server is maintained by a core enterprise serving as a consensus node, runs a side chain process, is connected to a public chain for data storage, and can effectively improve the transaction efficiency on the side chain.
In one embodiment, the hash values corresponding to raw material data, production data, sales data, and supervision data may be calculated by Merkle Tree (Merkle Tree) algorithm. Namely, the hash locking is performed through the merkel tree, and then the resulting merkel Root (Merkle Root) is written into the main chain. Once the tracing information is tampered, the Merkle Root is changed, and the trueness and the reliability of the data are ensured.
As shown in fig. 5, after a round of transaction is finished, the information uploaded by the nodes such as the supply institution, the production institution, the distribution institution, the monitoring institution and the like on the side chain is used as the leaf node of the Merkle Tree, and the hash value of the leaf node is calculated. If there are multiple supply agencies or dealerships, the information of the different nodes is handled as leaf nodes, respectively. After obtaining a plurality of hash values (H1, H2, H3 …), pairwise operations are performed on (H1, H2, H3 …) to obtain the hash values. This loops until the root hash MerkleRoot is obtained.
And binding the Merkle Root with the batch number of the product, synchronizing to the main chain, and then taking the Merkle Root as a traceability verification code of the batch of products. After inquiring the product traceability information, the consumer obtains the Merkle Root by using the same method, and the Merkle Root is compared with the reliable value on the main chain, so that whether the traceability information of the product is tampered or not can be judged. Once the data is wrong, the regulatory body can use the MerkleTree algorithm to more quickly locate which branch the tampered data comes from and to undertake accountability to a specific link in the supply chain.
In one embodiment, a Digital object unique Identifier (DOI) for the product may also be generated, such as a two-dimensional code, barcode, etc., to facilitate more convenient traceability of the product by the consumer. Taking the two-dimensional code as an example, the consumer can access data associated with the product, such as production data, sales data, raw material data, supervision data, and the like of the cosmetic, by scanning the two-dimensional code corresponding to the product. Once the product has a problem, the consumer can trace the source of the product by scanning the two-dimensional code at any time to find the problem, so that the product is very convenient.
