Description

Knowledge sharing method and device based on blockchain smart contract, and storage medium

Technical Field

The present invention relates to the field of blockchain technology, and in particular to a knowledge sharing method and device based on blockchain smart contracts, and a storage medium.

Background technique

In large organizations with internal competition and external cooperation, there are both internal competition and external cooperation between different sub-organizations (such as different sub-organizations within a large enterprise). In large enterprises, each sub-organization will generate a variety of knowledge in the process of carrying out work, and this knowledge is recorded through different carriers. However, there is little motivation for knowledge sharing between different sub-organizations of the same enterprise, and relying on administrative means to promote knowledge sharing is inefficient. Therefore, from the perspective of enterprise organization, the knowledge of the enterprise is scattered in various sub-organizations, making it difficult to achieve knowledge aggregation and efficient knowledge sharing between different organizations. Therefore, proposing a new knowledge sharing method that enables various knowledge carriers to be transmitted in a timely manner between knowledge owners and knowledge demanders, thereby achieving efficient knowledge circulation, is one of the problems that need to be solved in the process of knowledge sharing.

The present invention discloses a knowledge sharing method and device based on blockchain smart contracts, and a storage medium, which can build a knowledge sharing platform based on blockchain smart contracts and provide a communication channel for various knowledge carriers between knowledge owners and knowledge demanders. The following are detailed descriptions.

Embodiment 1

Please refer to Figure 1, which is a flow chart of a knowledge sharing method based on blockchain smart contracts disclosed in an embodiment of the present invention. The knowledge sharing method based on blockchain smart contracts described in Figure 1 can be applied to a knowledge sharing device based on blockchain smart contracts, and the knowledge sharing device based on blockchain smart contracts can be integrated in a cloud server, a local server or a blockchain, which is not limited in the embodiment of the present invention. As shown in Figure 1, the knowledge sharing method based on blockchain smart contracts can include the following operations:

101. Obtain the knowledge carrier data uploaded by the first source account, write the knowledge carrier data into the blockchain according to the preset knowledge on-chain smart contract, obtain the on-chain knowledge carrier data, and generate marking information corresponding to the on-chain knowledge carrier data.

In the embodiment of the present invention, specifically, the marking information at least includes source account information of the knowledge carrier data.

In the embodiment of the present invention, optionally, the knowledge carrier data can be data containing knowledge content in any form such as text, video, voice and picture. The first source account can be any account or an account with preset permissions. The knowledge carrier data is written into the blockchain according to the knowledge chain smart contract to obtain the knowledge carrier data on the chain. Then, the source account information of each knowledge carrier data is recorded by the marking information, so that the source account of each knowledge carrier data on the chain can be traced. It can be seen that the embodiment of the present invention first builds a knowledge sharing platform based on the blockchain smart contract. At the same time, based on the blockchain technology, each time the knowledge carrier data is obtained, it is automatically written into the blockchain through the knowledge chain smart contract, making the management of the knowledge sharing platform more efficient.

102. Obtain request information sent by the requesting account.

In the embodiment of the present invention, specifically, the request information is used to request the output of the target chain knowledge carrier data in the blockchain, and the request information at least includes the request account information for sending the request information.

In the embodiment of the present invention, the requesting account may be any account or an account with preset permissions, wherein the requesting account and the first source account may be the same account or different accounts. When the requesting account wants to obtain the target chain knowledge carrier data it needs from the blockchain, it may send a request message to request the output of the target chain knowledge carrier data.

103. If the requesting account information is consistent with the source account information, the knowledge carrier data on the target chain is output to the requesting account.

In an embodiment of the present invention, specifically, the source account information is recorded in the tag information corresponding to the knowledge carrier data on the target chain, and the request account information is recorded in the request information. When the request account information is consistent with the source account information, it means that the request account and the first source account are the same account. At this time, the knowledge carrier data on the target chain is directly output to the request account.

104. If the requesting account information is inconsistent with the source account information, it is determined whether the requesting information satisfies the data output conditions in the preset knowledge sharing smart contract. If it is determined that the requesting information satisfies the data output conditions in the knowledge sharing smart contract, the knowledge carrier data on the target chain is output to the requesting account.

In the embodiment of the present invention, specifically, when the requesting account information is inconsistent with the source account information, it means that the requesting account and the first source account are not the same account, and it is necessary to further determine whether the requesting information meets the data output conditions in the preset knowledge sharing smart contract. When the requesting information meets the data output conditions in the knowledge sharing smart contract, the knowledge carrier data on the target chain is output to the requesting account. The present invention uses the smart contract technology of blockchain to improve the efficiency of judging data output conditions.

It can be seen that the implementation of the knowledge sharing method based on blockchain smart contracts in the embodiment of the present invention can build a knowledge sharing platform based on blockchain, so that various knowledge carriers can be efficiently transmitted between knowledge owners and knowledge demanders, thereby realizing efficient circulation of knowledge.

In an optional embodiment, the request information further includes target transaction resources; the knowledge sharing method based on blockchain smart contract may further include the following operations:

According to the preset knowledge pricing smart contract, the quantity range of the demand transaction resources corresponding to the on-chain knowledge carrier data is determined, and the quantity range at least includes the minimum quantity threshold.

Furthermore, the above-mentioned judgment request information whether it meets the data output conditions in the preset knowledge sharing smart contract specifically includes:

Determine whether the quantity of target transaction resources is greater than or equal to a minimum quantity threshold;

If the quantity of the target transaction resources is greater than or equal to the minimum quantity threshold, it is determined that the request information meets the data output conditions in the preset knowledge sharing smart contract;

Furthermore, after outputting the target chain knowledge carrier data to the requesting account, the above-mentioned knowledge sharing method based on blockchain smart contract may further include the following operations:

Send part or all of the target transaction resources to the source account corresponding to the knowledge carrier data on the target chain;

According to the quantity of target transaction resources in several historical request information corresponding to the knowledge carrier data on the target chain, according to the knowledge pricing smart contract, the quantity range of demand transaction resources corresponding to the knowledge carrier data on the target chain is updated.

In this optional embodiment, the target transaction resource may be a virtual currency or a transaction medium such as points. Optionally, the demand transaction resource is a quantity range of transaction resources that meet the transaction requirements determined for the target knowledge carrier data by a preset knowledge pricing smart contract. The quantity range includes at least a minimum quantity threshold, may include a maximum quantity threshold, or may not have an upper limit. When the requesting account believes that the target transaction resource is more important or worth more than the money, it may actively send transaction resources that exceed the minimum quantity threshold, thereby achieving a purpose of rewarding or rewarding the source account of the target knowledge carrier data.

In this optional embodiment, specifically, part or all of the target transaction resources are sent to the source account corresponding to the knowledge carrier data on the target chain. When it is necessary to encourage the source account to actively upload the knowledge carrier data, all of the target transaction resources can be sent to the source account. When the platform needs to collect service fees, part of the transaction resources can also be deducted from the target transaction resources and part of the target transaction resources can be sent to the source account.

In this optional embodiment, specifically, according to the knowledge pricing smart contract, the quantity range of the demand transaction resources corresponding to the knowledge carrier data on the target chain is updated. Since the quantity range of the demand transaction resources is automatically priced by the knowledge pricing smart contract, in order to improve the rationality of pricing, it is also necessary to consider the requesting account's recognition of the quantity of the transaction resources. For example, if the target transaction resources paid by most customers for a certain target knowledge carrier data are far greater than the minimum quantity threshold, it means that the pricing of the target knowledge carrier data is low, and the quantity range of the demand transaction resources corresponding to the target knowledge carrier data should be updated. Optionally, the quantity range of the demand transaction resources corresponding to the target knowledge carrier data can be updated by taking the average quantity of the target transaction resources in several historical request information, or by fitting the distribution of the quantity of the target transaction resources in several historical request information by normal distribution, and then determining the optimal quantity range of the demand transaction resources corresponding to the target knowledge carrier data.

It can be seen that the implementation of the knowledge sharing method based on blockchain smart contracts in this optional embodiment improves the enthusiasm of the source account to upload knowledge carrier data by relying on transaction resources to trade knowledge carrier data, and can also measure the requesting account's recognition of the transaction resource quantity range by the number of target transaction resources customized by the requesting account. In addition, the number of target transaction resources customized by the requesting account can also be used to feedback and adjust the quantity range of demand transaction resources corresponding to the target knowledge carrier data, thereby providing a reasonable transaction resource quantity range for the target knowledge carrier data, and ultimately achieving efficient circulation of knowledge.

In another optional embodiment, the above-mentioned knowledge sharing method based on blockchain smart contract may also include the following operations:

Obtain the derived knowledge carrier data uploaded by the second source account, write the derived knowledge carrier data into the blockchain according to the knowledge on-chain smart contract, and obtain the derived on-chain knowledge carrier data;

And, after outputting the target chain knowledge carrier data to the requesting account, the above-mentioned knowledge sharing method based on blockchain smart contract may further include the following operations:

Determine whether the data type of the knowledge carrier data on the target chain is a derived type;

If it is determined that the data type of the knowledge carrier data on the target chain is a derivative type, then according to the target transaction resources, the first part of the transaction resources in the target transaction resources is sent to the source account corresponding to the knowledge carrier data on the target chain, and the second part of the transaction resources in the target transaction resources is sent to the source account corresponding to the knowledge carrier data on the target original chain, wherein the knowledge carrier data on the target original chain is the knowledge carrier data on the original chain corresponding to the knowledge carrier data on the target chain;

In this optional embodiment, specifically, the sum of the number of the first part of transaction resources and the second part of transaction resources does not exceed the number of target transaction resources. The derived knowledge carrier data is obtained by modifying the knowledge content of at least one original on-chain knowledge carrier data. For example, the derived knowledge carrier data is a PPT introducing blockchain technology. The production of this PPT refers to the original on-chain knowledge carrier data already existing in several blockchains: Document 1 for introducing the history of blockchain development, Video 2 for explaining the operating principle of blockchain, and PPT 3 for analyzing the advantages of blockchain, etc.

It can be seen that the knowledge sharing method based on blockchain smart contracts in the optional embodiment can record the adaptation information of the derived on-chain knowledge carrier adapted from the original on-chain knowledge carrier data, and reasonably allocate the target transaction resources. The source account corresponding to the original on-chain knowledge carrier data can also obtain a corresponding part of the transaction resources, making the allocation process of the target transaction resources in the embodiment of the present invention more reasonable, thereby encouraging the source account to upload higher-quality knowledge carrier data and realize efficient circulation of knowledge.

In another optional embodiment, the above-mentioned writing of the derived knowledge carrier data into the blockchain according to the knowledge on-chain smart contract to obtain the derived on-chain knowledge carrier data may include the following operations:

Obtaining knowledge content duplication information between the derived knowledge carrier data and each original on-chain knowledge carrier data corresponding to the derived knowledge carrier data;

Determine the adaptation parameters of the derived knowledge carrier data according to the derived knowledge carrier data and all knowledge content duplication information;

Determine whether the adaptation parameter is greater than or equal to a preset adaptation parameter threshold. If the adaptation parameter is greater than or equal to the adaptation parameter threshold, write the derived knowledge carrier data into the blockchain to obtain the derived knowledge carrier data on the chain;

Furthermore, before sending the second part of the transaction resources in the target transaction resources to the source account corresponding to the knowledge carrier data on the target original chain, the method may further include the following operations:

For each target original chain knowledge carrier data corresponding to the target chain knowledge carrier data, determine the correlation parameter between the target chain knowledge carrier data and the target original chain knowledge carrier data based on the knowledge content duplication information between the target chain knowledge carrier data and the target original chain knowledge carrier data; determine the number of the second part of transaction resources corresponding to the target original chain knowledge carrier data based on the correlation parameter.

In this optional embodiment, specifically, the knowledge content duplication information is used to represent the repeated knowledge content between the derived knowledge carrier data and the original on-chain knowledge carrier data, wherein the repeated knowledge content is the knowledge content whose similarity between the derived knowledge carrier data and the original on-chain knowledge carrier data is greater than or equal to a preset similarity threshold.

In this optional embodiment, specifically, the adaptation parameter is used to measure the originality of the knowledge content of the derived knowledge carrier data, which is determined by the derived knowledge carrier data and all knowledge content duplication information. Optionally, the proportion of original knowledge content is determined based on the proportion of all knowledge content duplication information, and the adaptation parameter is finally confirmed. If the adaptation parameter is less than the preset adaptation parameter threshold, it means that the originality of the corresponding derived knowledge carrier data is not enough and is not suitable for writing into the blockchain. Determining the adaptation parameter and relevance parameter through knowledge content duplication information can be completed by the following operations:

If the knowledge carrier data A on the target chain is of a derivative type, it has corresponding knowledge carrier data on the original chain: target original chain knowledge carrier data 1, target original chain knowledge carrier data 2, target original chain knowledge carrier data 3; wherein, the knowledge content duplication information between the target chain knowledge carrier data A and each original chain knowledge carrier data is: knowledge content duplication information 1, knowledge content duplication information 2, knowledge content duplication information 3; through analysis, the content proportions of knowledge content duplication information 1, knowledge content duplication information 2, and knowledge content duplication information 3 in the target chain knowledge carrier data A are 0.15, 0.2, and 0.25, respectively, then it can be determined that the adaptation parameter is 0.4. If the preset adaptation parameter threshold is 0.3, then the adaptation parameter is greater than the preset adaptation parameter threshold, which means that the corresponding derivative knowledge carrier data is sufficiently original and can be written into the blockchain. Furthermore, based on knowledge content duplication information 1, knowledge content duplication information 2, and knowledge content duplication information 3, it can be determined that the correlation parameters between the knowledge carrier data A on the target chain and the knowledge carrier data 1 on the target original chain, the knowledge carrier data 2 on the target original chain, and the knowledge carrier data 3 on the target original chain are: 0.15, 0.2, and 0.25, respectively.

It can be seen that the implementation of the knowledge sharing method based on blockchain smart contracts in this optional embodiment can screen out the derivative on-chain knowledge carrier data that meets the original requirements, and can determine the amount of the second part of transaction resources that need to be allocated to the source account corresponding to the original on-chain knowledge carrier data based on the correlation between the derivative on-chain knowledge carrier data and the original on-chain knowledge carrier data, thereby making the allocation method of transaction resources in the embodiment of the present invention more reasonable and fair, increasing the enthusiasm of source users to upload knowledge carrier data, and realizing efficient circulation of knowledge.

In yet another optional embodiment, the above-mentioned obtaining of knowledge content duplication information between the derived knowledge carrier data and each original on-chain knowledge carrier data corresponding to the derived knowledge carrier data may include the following operations:

Determine semantic features of the derived knowledge carrier data according to the derived knowledge carrier data;

For each original on-chain knowledge carrier data corresponding to the derived knowledge carrier data, obtain several associated semantic features between the derived knowledge carrier data and the original on-chain knowledge carrier data; determine the weight value corresponding to each associated semantic feature based on each associated semantic feature and the semantic feature; determine the knowledge content duplication information between the derived knowledge carrier data and the original on-chain knowledge carrier data based on each associated semantic feature and the weight value corresponding to the associated semantic feature.

In this optional embodiment, specifically, the semantic feature is used to represent the knowledge content expressed by the derived knowledge carrier data, and the associated semantic feature is used to represent the repeated knowledge content between the derived knowledge carrier data and the original knowledge carrier data on the chain.

In this optional embodiment, the repeated knowledge content between the derived knowledge carrier data and the original knowledge carrier data on the chain needs to consider its importance to determine the final knowledge content duplication information. For example, for some background knowledge introduction and other knowledge content involved in the derived knowledge carrier data, since its contribution to the degree of originality is not high, it is necessary to reduce the proportion of its influence on the degree of originality. Therefore, in this optional embodiment, the weight value corresponding to each associated semantic feature and semantic feature is determined. Optionally, in the process of determining the weight value, the knowledge expression level of the associated semantic feature in the semantic feature is first determined: for example, one or more combinations of background knowledge introduction, core idea expression, explanatory footnotes, summary expression, etc., and finally the weight value is determined according to the expression level.

It can be seen that the implementation of the knowledge sharing method based on blockchain smart contracts in this optional embodiment can determine the final knowledge content duplication information according to the importance of the repeated knowledge content between the derived knowledge carrier data and the original knowledge carrier data on the chain, making the determination process of the knowledge content duplication information more reasonable, making the allocation method of transaction resources in the embodiment of the present invention more reasonable and fair, thereby increasing the enthusiasm of source users to upload knowledge carrier data and realizing efficient circulation of knowledge.

In yet another optional embodiment, after outputting the target chain knowledge carrier data to the requesting account, the method may further include the following operations:

Obtain feedback information uploaded by the requesting account, including evaluation information and/or correction information;

When the feedback information includes evaluation information, the preset knowledge evaluation smart contract is used to determine whether the evaluation information meets the preset evaluation conditions.

Embodiment 2

Please refer to Figure 2, which is a flow chart of another knowledge sharing method based on blockchain smart contracts disclosed in an embodiment of the present invention. The knowledge sharing method based on blockchain smart contracts described in Figure 2 can be applied to a knowledge sharing device based on blockchain smart contracts, and the knowledge sharing device based on blockchain smart contracts can be integrated in a cloud server, a local server or a blockchain, which is not limited in the embodiment of the present invention. As shown in Figure 2, the knowledge sharing method based on blockchain smart contracts can include the following operations:

201. Obtain the knowledge carrier data uploaded by the first source account.

In the embodiment of the present invention, specifically, the knowledge carrier data includes knowledge carrier content data and first label data, and the first label data is used to indicate a target data block to which the knowledge carrier data needs to be written.

In an embodiment of the present invention, optionally, the knowledge carrier content data may be data containing specific knowledge content in any form such as text, video, voice, and picture, and the first label data may be used to indicate the knowledge field or knowledge category to which the knowledge carrier content belongs. Optionally, the first label data may be obtained based on a description statement provided or filled in by a source account when uploading the knowledge carrier data, or may be directly determined by a source user by selecting the knowledge field or knowledge category to which the knowledge carrier data belongs.

202. Generate keywords based on the knowledge carrier content data, and determine second label data of the knowledge carrier data based on the keywords.

In an embodiment of the present invention, specifically, the second label data is used to indicate a target data block to be written into the knowledge carrier data. The second label data is obtained by analyzing the content of the knowledge carrier. Specifically, keywords are generated based on the content data of the knowledge carrier, and the second label data of the knowledge carrier data is determined based on the keywords. Optionally, multiple keywords that can summarize the content of the knowledge carrier are extracted by analyzing the content data of the knowledge carrier. For example, for text-type knowledge carrier data, the content expressed by the text is analyzed and the text keywords are extracted through a preset content analysis model. Optionally, the second label data of the knowledge carrier data is determined based on the keywords. The first correlation between each second label data and each standard keyword can be preset, and then the second correlation between the keyword and the standard keyword can be analyzed. The second label data of the knowledge carrier data is determined based on the keywords in combination with the first correlation and the second correlation.

In the embodiment of the present invention, since the first label data comes from the first source account, it is difficult for the first source account to fully and accurately describe the knowledge carrier data uploaded by it. For example, the source account believes that the knowledge carrier data uploaded by it belongs to knowledge fields such as blockchain, knowledge sharing, and trading platform, but in fact, the knowledge carrier data uploaded by it also belongs to knowledge fields such as data transmission, data classification, and data content similarity analysis. If the knowledge field of the knowledge carrier data is measured only by the first label data, it will cause the problem of insufficient accuracy and comprehensiveness, which may cause the knowledge carrier data to not be written into the correct data block. Therefore, the embodiment of the present invention also determines the second label data, wherein the second label data is determined by the knowledge carrier content data, and can fully and accurately describe the uploaded knowledge carrier data. It can be seen that the embodiment of the present invention obtains the second label by processing the knowledge carrier data, and can fully and accurately describe the uploaded knowledge carrier data.

203. According to the first label data and the second label data, the knowledge carrier data is written into the corresponding target data block to obtain the on-chain knowledge carrier data; and marking information corresponding to the on-chain knowledge carrier data is generated.

In the embodiment of the present invention, specifically, the marking information at least includes the source account information of the knowledge carrier data; the blockchain includes a plurality of target data blocks, each target data block is used to store the knowledge carrier data of a corresponding category.

It can be seen that in the embodiment of the present invention, different data blocks store different categories of knowledge carriers, so that the knowledge carrier data is classified and stored, which is convenient for searching and managing the knowledge carrier data on the chain. Furthermore, the second label data is determined by the knowledge carrier content data, which can comprehensively and accurately describe the uploaded knowledge carrier data. Therefore, the embodiment of the present invention can realize a more accurate and comprehensive classification of the knowledge carrier data by combining the first label data and the second label data, thereby improving the efficiency of the knowledge sharing process.

204. Obtain request information sent by the requesting account.

305 If the requesting account information is consistent with the source account information, the knowledge carrier data on the target chain is output to the requesting account.

206. If the requesting account information is inconsistent with the source account information, determine whether the requesting information satisfies the data output conditions in the preset knowledge sharing smart contract. If it is determined that the requesting information satisfies the data output conditions in the knowledge sharing smart contract, output the knowledge carrier data on the target chain to the requesting account.

In the embodiment of the present invention, for other descriptions of steps 204-206, please refer to the detailed description of steps 102-104 in the first embodiment, and the embodiment of the present invention will not be repeated here.

It can be seen that the implementation of the knowledge sharing method based on blockchain smart contracts in the embodiment of the present invention can build a more efficient knowledge sharing platform based on blockchain smart contracts, and can achieve more accurate and comprehensive classification of knowledge carrier data, so that various knowledge carriers can be efficiently disseminated between knowledge owners and knowledge demanders, thereby realizing efficient circulation of knowledge.

In an optional embodiment, after step 203, the method may further include the following operations:

For each first source account, determining the domain label data corresponding to the first source account according to the first label data and the second label data of all knowledge carrier data uploaded by the first source account, where the domain label data is used to indicate the knowledge domain corresponding to the first source account;

In this optional embodiment, further optionally, the method may also include the following operations:

Obtain the announcement information and third-party reward transaction resources sent by the requesting account. The announcement information is used to describe the knowledge content that the requesting account needs to obtain;

According to the announcement information, determine the index label data corresponding to the announcement information, where the index label data is used to match the first label data, the second label data, and the domain label data;

Determine whether there is matching on-chain knowledge carrier data in the blockchain, wherein the matching degree between the first label data and the second label data of the matching on-chain knowledge carrier data and the index label data is greater than or equal to a preset matching degree threshold;

If it is determined that there is a matching on-chain knowledge carrier data in the blockchain, the matching on-chain knowledge carrier data is sent to the requesting account. If the confirmation information sent by the requesting account is obtained, all or part of the third reward transaction resources are sent to the source account corresponding to the matching on-chain knowledge carrier data;

If it is determined that there is no matching on-chain knowledge carrier data in the blockchain, an announcement message is sent to all target first source accounts, where the matching degree between the domain label data and the index label data corresponding to the target first source account is greater than or equal to a preset matching degree threshold;

Obtain the matching knowledge carrier data uploaded by the target first source account, send all the matching knowledge carrier data to the requesting account, and if the confirmation information sent by the requesting account for the target matching knowledge carrier data among all the matching knowledge carrier data is obtained, then send all or part of the transaction resources in the third reward transaction resource to the source account corresponding to the target matching knowledge carrier data.

It can be seen that, by implementing the knowledge sharing method based on blockchain smart contracts in the optional embodiment, when the knowledge demander cannot directly determine the target chain knowledge carrier data to be obtained according to his own knowledge demand, or when the target chain knowledge carrier data that meets the knowledge demand does not exist in the blockchain, the required knowledge carrier data can be obtained by sending announcement information through the request account. In the optional embodiment, the request account can be helped to accurately find the corresponding target chain knowledge carrier data in the blockchain according to the announcement information, thereby improving the efficiency of knowledge sharing. In addition, in the embodiment of the present invention, the field label data is determined for the source account according to the knowledge carrier data frequently uploaded by the source user, and the knowledge field that each source account is good at can be measured. When there is no target chain knowledge carrier data that meets the knowledge demand in the blockchain, the source account that is capable of providing the target chain knowledge carrier data can be confirmed according to the announcement information, so that the connection between the knowledge demander and the knowledge owner can be accurately established, so that various knowledge carriers can be efficiently transmitted between the knowledge owner and the knowledge demander, thereby realizing the efficient circulation of knowledge.

It can be seen that the device described in Figure 4 improves the enthusiasm of source accounts to upload knowledge carrier data by relying on trading resources to trade knowledge carrier data. It can also measure the requesting account's recognition of the range of trading resource quantities by the number of target trading resources customized by the requesting account. In addition, it can also use the number of target trading resources customized by the requesting account to feedback and adjust the range of demand trading resources corresponding to the target knowledge carrier data, thereby providing a reasonable range of trading resource quantities for the target knowledge carrier data, and ultimately achieving efficient circulation of knowledge.

It can be seen that the device described in Figure 4 can record the adaptation information of the derived on-chain knowledge carrier adapted from the original on-chain knowledge carrier data, and reasonably allocate the target transaction resources. The source account corresponding to the original on-chain knowledge carrier data can also obtain a corresponding part of the transaction resources, making the allocation process of the target transaction resources in the embodiment of the present invention more reasonable, thereby encouraging the source account to upload higher-quality knowledge carrier data and realize efficient circulation of knowledge.

According to the correlation parameter, determine the quantity of the second part of the transaction resources corresponding to the target original chain knowledge carrier data.

It can be seen that the device described in FIG4 can screen out the derivative on-chain knowledge carrier data that meets the original requirements, and can determine the amount of the second part of transaction resources that need to be allocated to the source account corresponding to the original on-chain knowledge carrier data based on the correlation between the derivative on-chain knowledge carrier data and the original on-chain knowledge carrier data, so that the allocation method of transaction resources in the embodiment of the present invention is more reasonable and fair, and the enthusiasm of source users to upload knowledge carrier data is improved, so as to realize the efficient circulation of knowledge.
