Detailed Description
In order to make the technical means and technical effects achieved by the technical means of the present invention more clearly and more perfectly disclosed, the following embodiments are provided, and the following detailed description is made with reference to the accompanying drawings:
and creating an enterprise credit union chain, and forming a plurality of endorsement nodes in a form that a plurality of organizations reach intelligent contracts respectively and correspondingly, wherein the endorsement nodes form the enterprise credit union chain. The conceptual diagram of the Corporate credit (CC, corporation credit) alliance network of the present embodiment is shown in fig. 1.
The administrator to which the organization belongs registers. The method is realized based on Public Key Infrastructure (PKI), an administrator needs to create a public key and a private key during registration, the private key encrypts identity information of the administrator to obtain a digital signature, and the digital signature can be verified through the public key PK when the identity information of the administrator needs to be verified. Verification of the identity information is provided by a Management Service Provider (MSP) that is capable of determining not only the validity of the digital certificate, but also whether the digital certificate is from a trusted certificate authority.
The transaction request is lifted. The user lifts a transaction request to the endorsement node, and the transaction request consists of a message header and a message structure. The message header comprises a channel header (channeliHeader) and a signature header (SignatureHeaader), and the channel header comprises a channel and related information of the intelligent contract, such as a channel ID, an address, a timestamp and the like, so that the communication and other communications are ensured not to interfere with each other. The content of the message structure mainly comprises basic enterprise information, industrial and commercial information, operation information, risk information, logistics information, intellectual property, certificate of qualification and the like.
And (5) carrying out endorsement node processing. After the endorsement node acquires the transaction request, the endorsement node firstly verifies the requested message, including format verification, repeated submission verification (for protecting repeated attack), digital signature validity verification and authority verification. After the verification is passed, the endorsement node executes the submitted intelligent contract to generate a read-write set (Rwset), and completes signature to enter a waiting state, as shown in FIG. 2.
The ordering service node orders the broadcasts. When enough endorsement nodes are obtained in the last step (the number of the endorsement nodes can be set according to the percentage of the total number of the endorsement nodes, for example twenty percent), the application program can carry out signature verification, after passing, formal transactions are generated and broadcasted to the sequencing service nodes, the sequencing service nodes sequence according to the transaction messages of all channels and the channel IDs, generate blocks, and broadcast to the nodes of the whole network, as shown in FIG. 3.
Overall, the present embodiment can achieve the following technical effects:
(1) the enterprise credit alliance chain is built and maintained by organizations which reach contracts together, the authorities of alliance member nodes are all equal, the advantages are that the trusted exchange of data can be realized without mutual trust, the whole network is maintained together, the enterprise credit alliance chain can be added or quitted after authorization, and the enterprise credit alliance chain is a mode for reaching alliances among different organizations or organizations.
(2) The enterprise credit alliance chain has strict control on the mode of outputting resources externally, and a data generating party or a data collecting party is used as an accounting node to jointly manage, maintain and share the digital resources on the alliance chain. And other reader nodes can acquire enterprise credit data on a certain authority access chain through an interface, but do not participate in the consensus process, and the efficiency and the quality of resource management are effectively ensured through the mode.
(3) The enterprise credit union chain is managed assisted by intelligent contracts. The code driver does not need human intervention after deployment, so that the code driver can execute specified operations in a mode of reducing trust to the maximum extent. The contract mode can enable the management of resources to be more convenient and fast, and the automatic execution replaces artificial subjective judgment, so that the efficiency is high, and the method is more fair and objective.
(4) The back-billing node of the enterprise credit union chain not only comprises a bank, a government agency and the like in a traditional credit investigation system, but also comprises a park/building where the enterprise is located and participates in data management and sharing of the chain as a billing node, and a data enrichment enterprise credit analysis model such as logistics data, park payment information, employee attendance information and the like is obtained through a management/operation party of the park/building. The data is usually held by a park manager or a third-party operator, but the data is usually one hand data which can embody the vitality of the enterprise.
The above description is provided for the purpose of further elaboration of the technical solutions provided in connection with the preferred embodiments of the present invention, and it should not be understood that the embodiments of the present invention are limited to the above description, and it should be understood that various simple deductions or substitutions can be made by those skilled in the art without departing from the spirit of the present invention, and all such alternatives are included in the scope of the present invention.
