Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof. It should be understood that the specific embodiments described herein are merely illustrative of the invention, but do not limit the invention to only some, but not all embodiments.
The invention provides a data management method based on a multi-value chain collaborative mapping block chain, wherein the multi-value chain collaboration refers to business collaboration on and among multiple value chains of an enterprise to form a value chain collaboration alliance comprising a longitudinal collaborative relation and a transverse collaborative relation mesh structure.
For example, take a simple value chain collaboration federation diagram as shown in FIG. 1, where T1、T2、T3、T4、T5Representing different upstream raw material suppliers or businesses. M1, M2, M3, M4 represent different midstream part suppliers or enterprises. G1、G2、G3Representing different core manufacturing enterprises. B is1、B2…BnTo representDifferent downstream marketers or facilitators or enterprises. For simplicity of description, the term "enterprise" is used throughout the following to cover all commercial businesses or enterprises involved in the automotive industry, and is not separately described.
As can be seen from FIG. 1, T1～T5There may be data sharing or business collaboration between any two or any of the several. T is1～T5Can deliver value to M1～M4Then from M1 to M4Value transfer to G1～G3. Of course T is also possible1～T5Direct value transfer to G1～G3. Finally G1-G3Value is transferred to B1～Bn. The longitudinal value chain mainly comprising core manufacturing enterprises and the transverse cross-chain cooperation among the longitudinal value chains form value chain cooperation, and finally a meshed multi-valence value chain is formed.
In the multi-value chain collaboration alliance, data sharing or business collaboration is possible between the same layers, but data sharing or business collaboration is not available between different layers. The reason is that service data among different layers and different single value chains are not uniform, and data leakage is easy to occur due to the fact that no safe and reliable protection mode exists when data interaction is carried out among longitudinal value chains or transverse value chains, so that data isolation among the current value chains is caused.
Based on the above problem, referring to a flowchart of a data management method based on a multi-value chain collaborative mapping blockchain provided by the embodiment of the present invention shown in fig. 2, the method includes:
step 201: determining the overall information of the value chain cooperation alliance, wherein the overall information comprises: the type of each value chain, the corresponding business link, the business data corresponding to the business link, and the business operators of the enterprise.
Based on the current value chain cooperation alliance, how to map the value chain cooperation alliance into the block chain system is a core problem. Therefore, a mapping model needs to be established for all information included in the value chain cooperation alliance by taking the information of the comparison core as overall information. The general information of the value chain cooperation alliance comprises the following information: the type of each value chain, the corresponding business link, the business data corresponding to the business link, and the business operators of the enterprise.
The type of the value chain refers to the core function corresponding to the value chain. For example: supply chain, marketing chain, service chain, etc. It is colloquially understood that a supply chain may be understood as a chain of relationships formed by selling equipment supplies to other enterprises or purchasing equipment supplies from other enterprises. Marketing chain may be understood as a chain of relationships formed by marketing products. A service chain may be understood as a chain of relationships that is formed subsequent to the sale of a product.
For each value chain, according to the difference of the types of the value chains, the corresponding business links are different definitely, and the corresponding business data are different definitely and the related business operators are different definitely. For example: the business segment corresponding to the supply chain may include: production, purchase, production and purchase are two completely different business links, so that business data corresponding to production is different from business data corresponding to purchase, and business operators corresponding to production are different from business operators corresponding to purchase.
Step 202: mapping to form a block chain alliance based on the overall information; mapping to form channels in the block chain alliance based on the type of each value chain; mapping to form nodes in a block chain alliance based on the business link of each value chain; mapping to form unified data in the block chain alliance based on the service data corresponding to the service link; and mapping to form users in the blockchain alliance based on business operators of the enterprise.
Based on the above-mentioned value chain cooperation alliance, when mapping a blockchain, mapping in the form of blockchain alliance is a better choice, and as a blockchain alliance, in addition to comparing core overall information, other information needs to be combined to map the value chain cooperation alliance to form a blockchain alliance.
Based on the consideration, the general information of the value chain collaboration alliance is expressed by a quintuple to be mapped to form a block chain alliance, and the quintuple corresponding to the block chain alliance U is as follows:
U＝{Uid,Uname,UE,UA,UC}
wherein, UidIs a unique identifier of a blockchain federation to distinguish it from other blockchain federations. U shapenameIs the name of the Block chain alliance, UEThe channel set in the block chain alliance corresponds to the value chain, and the channel set is a set corresponding to the value chain.
UAThe channel manager set in the block chain alliance is generally a channel manager set, and each channel may include a plurality of service operators due to the plurality of channels, so that in order to facilitate the management of the channels, some service operators are selected as channel managers and have higher authority to perform operations such as management, maintenance and the like on the channels.
UCIs a cooperation condition of the block chain alliance, and the cooperation condition includes: admission conditions, cooperation declaration and privacy declaration of each value chain, wherein each value chain of the block chain alliance needs to be added, and the value chain can be added only when the cooperation conditions are met. There are many options for blockchain federation, one preferred option includes: fabric alliance.
For each value chain and between each channel: each value chain is mapped to one channel of the block chain alliance, and the channels mapped by all the value chains in the multi-value chain form a channel set UE。
For each channel EiCan be represented by a six-membered group as follows:
Ei＝{Eid,Ename,Etype,Eorg,Enode,Euser}
wherein, EidIs channel EiTo distinguish it from other channels. EnameIs channel EiName of (E), EtypeIs channel EiI.e., the type of value chain, such as the aforementioned supply chain, marketing chain, service chain, etc. If the supply chain has two: supply chain 1 and supply chain 2, and there are two corresponding channels. It should be noted that the block chainThe system is an integral system with huge data and computation amount, and the computation capability of the block chain system is determined according to the performance of the hardware equipment based on the limitation of the performance of the hardware equipment at present. Therefore, in order to improve the operation efficiency of the blockchain system, an enterprise can be specified to join only one of the channels of the same type. That is, for each enterprise, assuming that it joins the corresponding lane of the supply chain 1, the lane corresponding to the supply chain 2 cannot be added, and joins the lane corresponding to the supply chain 2, the corresponding lane of the supply chain 1 cannot be added. Of course, when the computation power is fully sufficient, the calculation power is not limited.
EorgIs channel EiI.e., the set of businesses in the corresponding value chain, the same channel may include multiple businesses. EnodeIs channel EiThe node set of (1) is an enterprise business link set corresponding to the value chain and a function link set of the channel, namely, a plurality of enterprises have the same business links, and the same business links form business link combination. EuserIs channel EiI.e., the set of business operators of the enterprise corresponding to the value chain.
For between business operators and users of blockchain alliances: and mapping business operators of enterprises into users in the blockchain alliance, and performing information management and authority control on the users through a user management module of the blockchain alliance.
User U in each block chain alliancesriRepresented by a quadruple as follows:
Usri＝{Usrid,Eid,Usrauthority,Enode}
wherein, UsridRepresenting a user UsriUnique identification of EidRepresenting a user UsriThe combination of the two can distinguish all business operators in the enterprise.
UsrauthorityRepresenting a user UsriThe set of permissions, the permissions may include: block chain management Authority, Enterprise administration Authority, EnodeRepresentation and user UsriAnd a user management module performs authority control on the aspect of business activities on the user based on the quaternary set.
For a business link and a block chain alliance node: mapping the business links into nodes in a block chain alliance, wherein business operators participate in the business links according to respective functions; the service management is realized through a node management module of the block chain alliance, and the method comprises the following steps: admission control, creation and deletion, deployment and offline of nodes; promoting the business process of a business link through the transaction management of the block chain alliance, wherein the business link comprises the following steps: procurement, warehousing, distribution, processing, production, sale, repair, maintenance, and settlement.
