Abstract
The utility model provides a school teaching system based on block chain technique, including user side, server, database, block chain customer end and block chain link point, server and block chain customer end are connected respectively to the user side, and the server connects block chain customer end and database respectively, and block chain customer end connects block chain node, the utility model relates to a rationally, convenient to use to decentralized's mode realizes that the distributed storage and the credibility of data verify, compromises the runnability of system with centralized mode, has realized effectively that college enterprise practices teaching activity is credible, moves high-efficiently.
Description
Technical Field
The utility model relates to a teaching equipment technical field, concretely relates to school teaching system based on block chain technique.
Background
At present, more and more colleges and universities in China implement a 3+1 talent culture mode reform of school-enterprise cooperative nurturing people, in order to ensure that practice teaching activities of students in enterprises for one year are accumulated to run efficiently and standardly and ensure the quality of enterprise practice teaching, more and more colleges and universities develop and deploy enterprise practice teaching management systems, and the achievement of teaching activities such as graduation design (thesis) guidance, teaching patrol, enterprise on-site investigation and the like is realized through the enterprise practice teaching management systems. However, because the traditional enterprise practice teaching management system has the centralized characteristic, the phenomena that the data is unsafe and the data is easy to be deleted or tampered by system developers or managers without authorization exist; secondly, because the data in the system influences the evaluation of students and teachers, part of users may rely on own wrong behaviors for own benefits, for example, some teachers may give a wrong result, but insist that the other score is submitted by the teachers, so that the information is wrong, because the system goes wrong or other possible misoperation of other managers is even intentionally modified, the system is undoubtedly caused to be in a questioned state, and thus the management of the system is troublesome; finally, the traditional enterprise practice teaching management information system is very easy to cause collective false situations, and individual departments may require teachers, students, even system developers or managers to modify data in batches by administrative means for meeting the requirements of evaluation and inspection of higher management departments, which brings great obstacles for the higher management departments to accurately know the teaching operation situations of lower departments. All this has a negative impact on the trustworthiness of the system to a certain extent, greatly increasing the credit and administrative costs of the system.
The traditional practical teaching management information system for the enterprises in colleges and universities is generally realized by adopting a B/S structural design, namely, a user accesses a server through a browser, and the server returns data according to the request of the user or stores the data into a database. However, such a design has the disadvantage of too high authority of developers and system managers, and is very easy to generate phenomena of counterfeiting, repudiation and corruption.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above-mentioned insufficiency, provide school teaching system based on block chain technique
The utility model aims at realizing through the following technical scheme:
the school teaching system based on the block chain technology comprises a user side, a server, a database, a block chain client side and block chain link points, wherein the user side is connected with the server and the block chain client side respectively, the server is connected with the block chain client side and the database respectively, and the block chain client side is connected with the block chain nodes.
The block link point includes N blocks.
Each chunk includes a chunk hash.
The 2 nd through nth blocks also include a previous block hash.
The utility model discloses following profitable effect has:
the utility model relates to a rationally, convenient to use to decentralized's mode realizes the distributed storage and the credibility verification of data, compromises the operational performance of system with centralized mode, has realized effectively that college enterprise practice teaching activity is credible, moves high-efficiently.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
The invention will be further described with reference to the accompanying drawings:
as shown in fig. 1, the school teaching system based on the blockchain technology includes a user end 1, a server 2, a database 3, a blockchain client 4 and a blockchain node 5, where the user end 1 is connected to the server 2 and the blockchain client 4, the server 2 is connected to the blockchain client 4 and the database 3, and the blockchain client 4 is connected to the blockchain node 5.
The blockchain node comprises N blocks 6.
Each chunk includes a chunk hash 7.
The 2 nd through nth blocks also include a previous block hash 8.
The working principle is as follows: in the practical teaching management system for college enterprises based on the blockchain technology, when a user submits teaching business data through the system, the system stores the business data into a traditional database, simultaneously sends core data of the business to a blockchain in a transaction mode, and returns the hash of the transaction to the user. Because the system interacts with the centralized database and the decentralized blockchain simultaneously, and the user can directly access the blockchain data through the third-party blockchain client, developers and system managers cannot tamper with the data of the system. If the developer or the system manager realizes the false or repudiation of the occurred behavior by modifying the system program or tampering the data of the system center database, the user can access the block chain data through the third party block chain client by means of the occurred transaction hash to realize the verification of the authenticity of the data.
