and the receiving module is positioned in the application layer and used for receiving the updated block data of the student file.
It should be noted that, after the first update module receives the block data of the student archive and the second broadcast information and updates the block data of the student archive, and after the updated block data of the student archive is obtained, the generation module in the data layer needs to generate the key information of the student archive, and transmit the key information to the calculation module in the excitation layer through the network layer, and meanwhile, the calculation module in the excitation layer transmits the right and interest data obtained by performing the right and interest data calculation according to the key information back to the second update module in the data layer for right and interest data update, so that it can be ensured that the right and interest data at any time are the latest right and interest data.
It is to be appreciated that the incentive layer may integrate economic return factors into the blockchain platform, which mainly includes incentive distribution mechanisms, etc., such as distribution of paid service revenue, contribution ranking, service scoring, etc. by each distribution node for student profile information.
Example 6
Referring to fig. 6, in an embodiment, the invention provides a block chain-based student profile extraction system, which includes:
the acquisition module is positioned in the application layer and used for acquiring and sending a request for extracting the student file;
the second verification module is positioned in the contract layer and used for verifying the triggering condition of the request, wherein the triggering condition is the user identity and the information validity of the student file;
the extraction module is positioned in the data layer and used for extracting block data of the student files and generating first broadcast information based on the request when the request of extracting the student files is received;
the first verification module is positioned in the consensus layer and used for receiving the block data and the first broadcast information of the student files and performing transaction verification on the block data of the student files to obtain verification information and second broadcast information based on the verification information;
the first updating module is positioned in the data layer and used for receiving the block data of the student file and the second broadcast information and updating the block data of the student file to obtain the updated block data of the student file;
and the receiving module is positioned in the application layer and used for receiving the updated block data of the student file.
In this embodiment, when the extraction module receives a request for extracting a student archive, before extracting block data of the student archive and generating first broadcast information based on the request, the acquisition module in the application layer needs to acquire the request for extracting the student archive first and send the request to the second verification module in the contract layer, and after the second verification module in the contract layer verifies a trigger condition of the request, the request meeting the trigger condition is transmitted to the extraction module in the data layer, so that each request transmitted to the data layer is reasonable and legal.
It should be understood that the contract layer is a student archive blockchain intelligent contract standard specification, i.e., various specifications and standards of the student archive industry are formulated and collected, contracts and scripts are implemented according to mainstream computer languages, such as java, C language, python, and the like, and federation nodes participating in the blockchain in the future need to be extended on the basis.
In summary, the student archive storage and extraction method and system based on the block chain provided by the invention have the beneficial effects that:
the storage and extraction of the student archives are combined with the block chain, so that the student archives are stored in the block chain nodes in a distributed mode, automatic synchronization can be achieved, and the risk of student archive data loss or deletion is reduced to the minimum. In addition, the block chain technology is characterized in that the data is not to be tampered, so that the learning tracks of students are recorded by the student files, and the most reliable and more comprehensive evidence and reference materials are provided for future student promotion, employment and talent selection.
After the data layer allocates a node to associate the new student profile and generate corresponding node data, the node data needs to be confirmed, so that the accuracy of the node data can be further ensured.
The data layer receives the block data of the student archive and the second broadcast information and updates the block data of the student archive, after the updated block data of the student archive is obtained, the data layer needs to generate key information of the student archive, the key information is transmitted to the incentive layer through the network layer, meanwhile, the incentive layer transmits right and interest data obtained by calculating right and interest data according to the key information back to the data layer for updating the right and interest data, and therefore the right and interest data at any time can be guaranteed to be the latest right and interest data.
When a request for extracting student archives is received, before block data of the student archives is extracted and first broadcast information based on the request is generated, an application layer needs to acquire the request for extracting the student archives and sends the request to a contract layer, and after the contract layer verifies triggering conditions of the request, the request meeting the triggering conditions is transmitted to a data layer, so that each request transmitted to the data layer is reasonable and legal.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
