Embodiment 1

[0037] Embodiment 1: as Figure 1-9 As shown, this blockchain-based network examination system adopts a dual-blockchain design, including a data storage layer, a blockchain core layer, a blockchain application layer, a blockchain interface layer, a business system layer, and a system user layer. The data storage layer API interface is connected to the blockchain core layer API interface for localized storage of blockchain data and supports the storage of structured and unstructured data. The core layer of the blockchain is connected to the application layer of the blockchain, which is used to realize the basic core functions of the blockchain such as encryption, consensus, building blocks, and contracts, and is convenient for carrying different blockchain services. The blockchain application layer and the blockchain interface layer are connected through the API interface, which is used to provide the realization of two business chains, the score chain and the exam chain of the...

Embodiment 2

[0058] Embodiment 2: as Figure 1-9 As shown, this blockchain-based network examination system adopts a dual-blockchain design, including a data storage layer, a blockchain core layer, a blockchain application layer, a blockchain interface layer, a business system layer, and a system user layer. The specific composition of the system is the same as that of Embodiment 1.

[0059] The method that this blockchain-based network examination system is used to manage network examinations is:

[0060](1) Block chain environment preparation: step 1, first determine the administrators and test sites participating in the online test business according to business needs, each manager sets up a test business chain BBC node, and each test site sets up an examinee score chain SBC node; Step 2, deploy the blockchain operating environment on each node, first deploy data storage, including Hbase, Redis, Mysql, allocate resources for data storage according to actual business needs and data volu...

Embodiment 3

[0064] Embodiment 3: as Figure 1-9 As shown, this blockchain-based network examination system adopts a dual-blockchain design, including a data storage layer, a blockchain core layer, a blockchain application layer, a blockchain interface layer, a business system layer, and a system user layer. The specific composition of the system is the same as that of Embodiment 1.

[0065] The method that this blockchain-based network examination system is used to manage network examinations is:

[0066] (1) Block chain environment preparation: step 1, first determine the administrators and test sites participating in the online test business according to business needs, each manager sets up a test business chain BBC node, and each test site sets up an examinee score chain SBC node; Step 2. Deploy the blockchain operating environment on each node. First, deploy data storage, including Hbase, Redis, and Mysql databases. According to actual business needs and data volume, allocate resourc...

Abstract

The invention relates to a network examination system based on a block chain and a method for managing the network examination by using the network examination system, belonging to the technical fieldof teaching management equipment. The system adopts double-block chain design, including a data storage layer, a block chain core layer, a block chain application layer, a block link interface layer,a business system layer and a system user layer. The API interface of the data storage layer is connected with the API interface of the core layer of the block chain, the core layer of the block chain is connected with the application layer of the block chain, and the application layer of the block chain is connected with the interface layer of the block link through the API interface. The blocklink interface layer is connected with the service system layer to realize the inquiry and writing of the block chain service. The business system layer is connected with the system user layer, whichprovides the interface between the user and the network examination service. The invention can prevent information from being lost or tampered with maliciously, construct a safe, reliable and non-tamper examination credit system, simplify the network examination management process, improve the network examination organization efficiency, and provide high-efficiency, convenient and humanized examination service for examinees.

Description

technical field [0001] The invention relates to a block chain-based network examination system and a method for managing network examinations by using it, and belongs to the technical field of teaching management equipment. Background technique [0002] The Ministry of Education's "National Medium- and Long-Term Educational Reform and Development Plan (2010-2020)" clearly proposes to build a "overpass" for lifelong learning, to promote vertical connection and horizontal communication of various levels of education, to provide multiple choices, and to meet the needs of individuals. Diverse learning and development needs. Examination, as an important evaluation link in the process of talent training, also needs to adapt to the needs of reform and development, and provide flexible, convenient, reasonable and fair personalized examination services for all kinds of learners. Traditional online examinations generally adopt a unified examination time, unified organization of propo...
