Embodiment 1, a decentralized provider information governance method based on block chain, the block chain adopts alliance chain architecture, governs and shares the key information of the provider with the help of alliance chain technology, the concrete process includes two steps, the first step is to carry on the only recognition and admittance to the provider, the second step is to carry on the decentralized auditing to the key information of the provider; the alliance chain comprises a management node and consensus nodes, wherein the management node is responsible for the admission audit of suppliers, the consensus nodes are composed of different suppliers and are responsible for the audit of key information of the suppliers, and the number of the consensus nodes is not less than 3; the architecture of the whole blockchain system comprises a data layer, a network layer, a consensus layer and a contract layer, wherein the contract layer is used for calling various applications.
Referring to fig. 1, the block chain-based decentralized provider information governance method specifically comprises the following steps: the supplier applies for uplink; identifying admission and broadcasting key information by a supplier; auditing key information; sharing key information records; and (5) information tracing and querying.
The management node performs centralized auditing on the admission of the supplier, ensures the uniqueness of the supplier, and provides a clear object for auditing and sharing the information of the supplier.
The verification of the key information of the supplier is realized in a decentralized mode, a data transaction application is initiated by the consensus node, the data transaction application is broadcasted to all nodes, and the data quality and the data authenticity are verified by all the nodes.
Each node needs to prove when applying for and checking the key information, and the authenticity and traceability of the information are solved by using the proof, so that the fusion of the information on the chain and the information under the chain is realized.
All information in the transaction and audit process of the supplier information is reserved by each node, the account book copies of each node are kept consistent, synchronous sharing and open transparency of the information are realized, and the authority and the availability of the supplier information are improved.
Vendor key information includes, but is not limited to: basic information, development investment funds, production investment funds, product and service capabilities, qualifications, and credit information and service levels.
The consensus algorithm of the alliance chain adopts supply chain equity certification SPoS based on equity certificate certification PoS, accounting nodes are determined according to research and development investment, production investment, credit level, service level and product function information, and consistency and order of the information are guaranteed.
Example 2: an experimental example of a decentralized provider information governance method based on a block chain is as follows:
product value chain and related enterprise map see FIG. 2;
the following table shows an association relationship schematic of a final assembly matching process on the upstream and downstream of a certain product, including 5 manufacturers, wherein the final assembly manufacturer is used as a chain master, and the roles in the block chain system are divided as follows:
information transfer and treatment processes:
node unit information formation
The constitution of the provider information includes: basic information, research and development investment funds, production investment funds, product and service capabilities, qualification and credit information, service levels, and the like.
Supplier joining application and auditing:
the supplier intentionally applies for the joining of the blockchain system, and can join the system after the approval.
The information submitted during application must include basic enterprise information including unified social credit codes, registered addresses, legal conditions and the like, and the information of product and service capacity, service level and the like is not submitted forcibly. The auditing work is mainly to identify and confirm the suppliers and ensure the validity of the production and operation.
The audit is completed by the management node assembly plant A, which determines whether other suppliers can join the blockchain system. The information submitted by the supplier is compared with the database of the external website, and an evaluation result of the reliability of the basic information is automatically generated for decision and confirmation of the final assembly plant A, so that the workload is greatly reduced, and the decision level is improved.
The automated alignment, assessment process uses a method comprising: OCR recognition, NLP, HASH data comparison, automatic document generation and the like.
Supplier capability auditing:
the auditing process of the supplier capacity is a process used by the suppliers which are added to the block chain system to show the current capacity and the future potential of the suppliers when the suppliers strive for orders.
For example, the matchmaker B submits certification materials such as annual delivery capacity, research and development invested funds, after-sales service capacity, industry evaluation level and the like in the blockchain system, broadcasts in the whole system, and other nodes check the content. If there is disagreement with the certified material, further testimony and review can be carried out, and the information passing the testimony can be written into the block chain system to be used as the credible information description of the supplier achieving the consensus. Information that does not pass the audit will not be written to the block.
Final assembly plant supplier management:
the final assembly plant A relies on the verification and confirmation of the block chain system on the authenticity and reliability of the information, and the evaluation of the capability of the supplier is realized by means of the whole product ecology, so that the cost and difficulty of the supplier management are greatly reduced, and the supplier information resource with high value and high reliability is formed.
