It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to facilitate searching of alloy material data by an alloy material practitioner, different types of data of the same or similar alloy materials do not need to be acquired from each platform.
As shown in fig. 1, a method for sharing alloy material data based on a block chain according to an embodiment of the present application may include the following steps:
When a user needs to search for data of a certain alloy material or a certain type of alloy material, a query request can be sent to the alloy material data sharing system based on the block chain, and the sent query request carries the component index of the alloy material requested to be queried.
And 102, searching a target alloy material data set in the alloy material data set stored in the block chain system according to the component index.
The alloy material data sharing system based on the block chain is stored with alloy material data sets of a plurality of alloy materials which can be shared in advance, wherein the alloy material data sets comprise component indexes of the alloy materials and alloy material sharing data. The composition index of the alloy material indicates the composition contained in the alloy material, and further, the content of each composition should be contained. The alloy material data set pre-stored in the system can be uploaded by a plurality of users, for example, a plurality of enterprises engaged in alloy material research and development and production can add in an alloy material data sharing system, and each enterprise added in the system can upload data obtained by research and development, experiments and production of the enterprise to the system, so that other enterprises can check the data and realize data sharing.
Further, the alloy material data set may also include a publisher of the alloy material data set and/or a data source of alloy material sharing data. The publisher represents a user who uploads alloy material data to a blockchain-based alloy material data sharing system, further facilitating copyright validation of the data. The data source indicates that the alloy material shared data is derived from equipment, calculation, reference and the like, wherein the equipment data can comprise experimental data, production data, product data and the like, the calculation data comprises manual calculation, software calculation and the like, and the reference data can comprise data from standards or documents, so that a user viewing the alloy material data set can conveniently know the source of the data, analyze the reliability of the data and the like.
After receiving the query request, the system searches a plurality of stored alloy material data sets, for example, based on a pattern recognition technology, according to the component indexes included in the query request, and if the similarity between the component indexes in the stored alloy material data sets and the component indexes in the query request reaches a preset threshold, the alloy material data set is used as a target alloy material data set. The number of the target alloy material data sets searched by the system can be one or more, and if the alloy material data sets consistent with or similar to the component indexes requested to be searched are not stored in the system, the number of the target alloy material data sets can also be 0.
When the similarity between the component indexes of the plurality of alloy material data sets and the component indexes in the query request reaches a preset threshold value, all the component indexes can be used as target alloy material data sets, or the alloy material data sets with higher similarity and a preset number of the alloy material data sets with higher similarity can be selected as the target alloy material data sets according to the similarity sequence.
And 103, outputting a target alloy material data set.
After finding the target alloy material data set, the alloy material data sharing system based on the block chain may send the target alloy material data set to the requester, or may also send a target alloy material data set list to the requester, and the requester determines whether to check each target alloy material data set. Further, when outputting, the target alloy material data sets may be sorted according to the above similarity.
In one possible implementation, the blockchain system includes: a federation chain and at least two private chains; the sender of the query request may be a node on a first private chain of the at least two private chains, and the target alloying material dataset may be stored on a node on a second private chain of the at least two private chains, the first private chain and the second private chain being connected by the federation chain. In one embodiment, as shown in fig. 2, the private chain of enterprise a and the private chain of enterprise B are both connected to a federation chain, and an Ai node in the private chain of enterprise a can obtain data stored on the private chain of enterprise B via the federation chain.
Further, the blockchain system may further include a public chain connected to the federation chain, as shown in fig. 3, so that other nodes except the node on the private chain can query the data stored on the enterprise private chain a and the enterprise private chain B through the public chain.
Optionally, the issuer of the alloy material data set may also set an authority for the alloy material data set issued thereby, for example, if the authority is set to be public or encrypted, the alloy material data set with the authority being public may be directly viewed by other users without performing authority verification, and the alloy material data set with the authority set to be encrypted may be viewed by other users after passing the authority verification.
Correspondingly, after the alloy material data sharing system based on the block chain finds the target alloy material data set, the authority information of the target alloy material data set is further obtained, if the authority information is the encrypted data set, whether a sender of the query request is an authorized user of the target alloy material data set is verified, and the target alloy material data set is sent to the authorized user after the sender is determined to be the authorized user. Or after the target alloy material data set is found, sending a target alloy material data set list to a sender of the query request, where the list may include an identifier of each target alloy material data set and corresponding permission information, and verifying whether the user is an authorized user when the user further requests to view the target alloy material data set of which the permission information is encrypted.
Specifically, the authorization information may be obtained in advance, for example, the a enterprise and the B enterprise negotiate to mutually authorize in advance; or when the target alloy material data set is requested to be checked, authorization is requested to be obtained temporarily, and authorization information is obtained after the target alloy material data set is approved by a publisher.
In some embodiments, a value factor may also be set for each alloy material data set. After the alloy material data sharing system based on the block chain finds the target alloy material data set, further obtaining a value factor of the target alloy material data set, and then returning identification information of the target alloy material data set and the value factor corresponding to the identification information to a sender of the query request; if the sender of the query request wants to view the target alloy material data set, the sender needs to pay a value integral corresponding to the value factor of the target alloy material data set and/or exchange data with the publisher of the target alloy material data set. For example, enterprise a wants to check the alloy material data set 1 published by enterprise B, and the value factor of the alloy material data set 1 is 10, corresponding to 10 value points; enterprise a may pay 10 value points to view alloy material dataset 1, may exchange data with enterprise B for alloy material dataset 2 issued by enterprise a with a value factor of 10, or may exchange data with enterprise B for alloy material dataset 3 with a value factor of 8 and pay 2 value points.
Further, after the alloy material data sharing system based on the block chain outputs the target alloy material data set to the sender of the query request, the alloy material data sharing system can also receive feedback information aiming at the target alloy material data set sent by the sender of the query request, and then updates the value factor of the target alloy material data set according to the feedback information.
For example, the value factor for each newly uploaded alloy material dataset is default 0, value factor + a after each viewing by other users; if the user approves the value factor + b after the user is checked by other users; if collected, the value factor + c; if the evaluation is poor, the value factor-d is obtained; if reported, the value factor-e. In addition, different value factor evaluation rules can be set for data of different data sources.
Furthermore, the above-mentioned blockchain system may further store information of viewed alloy material data sets, data exchange information of alloy material data sets, value factor update information of alloy material data sets, value point update information of each user, and the like.
In the above embodiment of the application, each user may upload various data acquired by the user through equipment, calculation, reference and the like to the blockchain system according to a format of a preset alloy material data set, and when performing data search, other users may search for data that is consistent with or similar to a component index from data stored in the blockchain system according to the component index.
