Detailed Description
In order to make the objects, technical solutions and advantages of the present disclosure more apparent, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step based on the embodiments in the description belong to the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
The scheme of the application provides an educational resource acquisition method based on a block chain. Many educational resources now come in the form of audio-video. A data resource is a type of metadata. In a block chain, grouping data in an external data source, a local database or a data lake into individual data resources, wherein the process can be called data resource utilization; then, performing value evaluation, pricing and property right determination on the recycled data, wherein the process can be called data asset transformation; the data after the assets are made to be available to the market for the data usage right, and after the data usage right is purchased, the data usage party may use the data in a batch download or API (Application Programming Interface) calling manner, which may be referred to as data commercialization. The data property may also be traded, but is less common than the usage rights. In addition to a data transaction scenario, data management scenarios such as data sharing, data opening, data authorized access and the like also require that data resource metadata is established first, and the best technical means for establishing the data resource metadata is a block chain. The mode of the application is realized by the technical means.
Fig. 1 is a schematic flow chart of a method provided in an embodiment of the present disclosure, and as shown in fig. 1, the method includes:
s101, building a block chain storing educational resources, and deploying an intelligent contract for managing the educational resources on the block chain; by embedding the intelligent contract, the block chain technology can complete the generation and evidence storage of the online education resource contract and construct the intelligent transaction system of the virtual economic education.
S102, receiving first request information of a user, determining the type of the user and the acquisition process of the educational resources according to the request information, and forming first feedback information;
s103, sending the first feedback information to a user;
s104, receiving and confirming second request information sent by a user, and storing the confirmed second request information in the block chain;
s105, calling data processing logic in the intelligent contract, and adding a specific identifier to the educational resource so that a user can at least inquire the second request information;
s106, the education resources including the second request information are sent out.
According to a specific embodiment of the present invention, in the process of determining the type of the user and the acquisition of the educational resources based on the request information, the method includes: determining whether the type of the user includes one of a school and an educational tutoring institution; if yes, the intelligent contract calls an acquisition flow of the education resources which are in accordance with the type.
Certainly, the type of the user may be a person or a family, the scene in such a case is simple, and generally, the person purchases the product without a bargaining space, so that the user only needs to send feedback information according to a preset flow. When the type of the user is school or education counseling organization, because the number of the purchased people is large, the related logic in the intelligent contract is started at the moment, the acquisition flow of the education resources is determined, and the first feedback information is formed for the user.
According to the specific embodiment of the invention, the first request information comprises the identity information of the user, and when the transaction is successful, the identity information is stored in the block chain, the data processing logic in the intelligent contract is called, and the first request information is processed to obtain the identity information of the user; and then saving the identity information to the blockchain.
According to an embodiment of the present invention, the receiving and confirming second request information sent by a user, and storing the confirmed second request information in the block chain, where the second request information includes: a user contracting with the intelligent contract for the buying and/or selling and/or use of the educational resource. After the intelligent contract confirms the contract, the transaction between the two parties is completed.
And after the transaction is completed, calling data processing logic in the intelligent contract, and adding a specific identifier to the educational resource so that the user can at least inquire the second request information. The specific implementation may be as follows: judging whether the educational resources comprise entity resources and digital resources; if the entity resource exists, printing the specific identification on the entity resource; and if the digital resource exists, embedding the specific identification into one frame of image of the digital resource. Then, the specific identifier can be connected with a query interface of the intelligent contract, and the second information can be queried in an online mode; or the second information is inquired in an off-line mode by writing the second request information into the specific identifier.
The specific Identifier may generally be a character string having uniqueness within a specific range, and for facilitating user interaction, the specific Identifier may further have a corresponding Digital Object Unique Identifier (DOI), specifically, for example, a two-dimensional code, a barcode, and the like, and the user may interact through code scanning. Taking the two-dimensional code as an example, the user can access the second information associated with the corresponding two-dimensional code by scanning the two-dimensional code, so as to query an educational resource purchase contract made by the user and the block chain. When the type of the user is school or education counseling institution, the student can inquire about the purchase contract by scanning the two-dimensional code, so as to know the purchase information and prevent cheating. The specific identifier may be information other than a character string, such as a two-dimensional code or biometric information.
According to the specific embodiment of the invention, the work of purchasing, using, paying and the like of various educational resources in the block chain is automatically completed by the system without manual operation, meanwhile, the purchase record cannot be tampered, is real and effective, and all transaction and contract data are permanently stored.
In one embodiment of the invention, after the consumer sends the purchase information, the system automatically sends the corresponding learning material to the consumer according to the operation rule of the intelligent contract, the logistics information of the material is tracked by the intelligent contract, and when the consumer confirms to receive the learning material, the system automatically completes payment without manual payment. In addition, the block chain also provides services such as online education and tool downloading, the learner can select proper learning services according to learning requirements, the learning services comprise one-to-one online education, point-of-knowledge lecture, difficult problem teaching and the like, and all resources and services can be independently consumed according to the individual requirements of the learner.
Based on the same idea, some embodiments of the present application further provide a device and a non-volatile computer storage medium corresponding to the above method.
