[0063] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0064] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0065] To address the problems of existing technologies, embodiments of this application provide a data on-chain compliance control method, apparatus, device, and storage medium. This data on-chain compliance control method can be applied to scenarios involving compliance control of on-chain data within a blockchain. The executing entity of this data on-chain compliance control method can be an electronic device configured with any node in the blockchain. The data on-chain compliance control method provided in this application embodiment is described below.

[0066] Figure 1 A flowchart illustrating a data on-chain compliance control method provided in one embodiment of this application is shown.

[0067] like Figure 1 As shown, the data on-chain compliance control method may specifically include the following steps:

[0068] First, S110, receive template configuration input from the target user based on the template operation interface.

[0069] Secondly, S120, in response to the template configuration input, generates a target data screening template.

[0070] Finally, in S130, the target data screening template is uploaded to the blockchain so that multiple nodes in the blockchain can screen the data to be uploaded to the blockchain based on the target data screening template before uploading it.

[0071] Therefore, by setting up a template operation interface, authorized users can visually create or modify data screening templates on their local node. By uploading these templates to the blockchain, all nodes within the blockchain can then screen the data on the chain based on this unified template. This allows for compliance control of on-chain data without requiring professional programming, preventing invalid or malicious data from being uploaded. This effectively reduces the development and maintenance costs required for compliance control of on-chain data, providing a secure, simple, self-maintaining, and self-synchronizing compliance control method.

[0072] The above steps are explained in detail below:

[0073] First, regarding S110, in this embodiment, the target user can configure a data screening template through the template operation interface. The target user is a user with template configuration permissions. The template configuration input includes modification input for an existing data screening template, or configuration input for creating a new data screening template. The data screening template is used to determine whether the data to be uploaded to the blockchain conforms to preset data specifications.

[0074] Here, the template operation interface can be a business compliance visual operation view interface, which can specifically include a selection area for data modules and an operation interface. Data modules can be fields in the template, such as record ID, system identification code, business identification code, etc. Template configuration can be performed by selecting or dragging data modules into the template.

[0075] In a specific example, a blockchain network may include several blockchain nodes such as the "Turning Stone into Gold" system, the order system, the integrated resource system, and the engineering construction system (ECMS). Each blockchain node can be set up with a template operation interface. Users with operation permissions can open the template operation interface on their node device, select the required data module in the candidate area, and transfer the data module from the candidate area to the operation interface, thereby completing the configuration process of the data screening template.

[0076] Secondly, regarding S120, the data screening template can be a combination of multiple data modules. The basic structure of the data screening template may include, for example, such as... Figure 2 The data modules shown include record ID, system identification code, business identification code, etc.

[0077] For example, users can configure data modules that can be uploaded to the blockchain according to business requirements and save the configuration results to the target data screening template.

[0078] In one optional implementation, the first area of ​​the template operation interface mentioned above displays M data modules, and the template configuration input is the input of dragging N data modules from the first area to the second area of ​​the template operation interface; wherein, M and N are positive integers, and M≥N;

[0079] Accordingly, the above-mentioned S120 may specifically include:

[0080] In response to the template configuration input, retrieve N data modules within the second region;

[0081] Generate a target data screening template based on N data modules.

[0082] Here, the first area of ​​the template operation interface can be the candidate area for the data module, and the second area of ​​the template operation interface can be the operation interface. The data module can be fields in the template, such as record ID, system identification code, business identification code, etc.

[0083] In a specific example, users can determine the fields corresponding to the data to be added to the chain based on business needs, and then drag and drop the data modules corresponding to these fields from the candidate area to the operation interface in the template operation interface, thereby generating the target data screening template according to the required data modules. The template operation interface is built based on the basic structure of the data screening template described in this solution, and the target data screening template can be generated after the user completes the operation.

[0084] In this way, through the above process, users can configure data screening templates in a simple interactive way on the visual template operation interface, and visually create or modify target data screening templates at this node, making the template creation and modification process more convenient and faster.

[0085] Finally, regarding S130, the data screening template can be uploaded to the blockchain network through the blockchain node configured in the device where the template was modified or created. In this way, other nodes in the blockchain network can obtain the data screening template and then perform compliance screening on the data uploaded from that node.

[0086] In one optional implementation, S130 may specifically include:

[0087] Store the target data screening template in the block data;

[0088] Upload block data to the blockchain.

[0089] Here, the target data screening template can be stored as a record in the block data. By uploading the block data to the blockchain, all nodes in the blockchain can synchronize the data corresponding to the data screening template.

[0090] In a specific example, if the target data screening template is generated in the Dian Shi Cheng Jin system, the blockchain nodes integrated in the Dian Shi Cheng Jin system will upload the screening template as record data to the chain and synchronize the block data through the blockchain network.

[0091] In this way, through the above process, each node in the blockchain can maintain blockchain data records according to a unified data screening template, preventing invalid or malicious data from being uploaded to the chain.

[0092] In one alternative implementation, the target data screening template is assigned a template-type identity identifier so that other nodes in the blockchain can obtain the target data screening template based on the template-type identity identifier.

[0093] Here, in order to allow other nodes in the blockchain to also obtain the full set of on-chain data screening templates, the blockchain nodes will upload the screening templates as record data and mark them with a special ID.

[0094] In a specific example, when the blockchain nodes integrated into the "Turning Stone into Gold" system upload screening templates as record data to the chain, they will mark them with a special ID. Blockchain nodes deployed on "Turning Stone into Gold" synchronize block data through the blockchain network, including records of the uploaded data screening template type. Blockchain nodes deployed on the order system, integrated resource system, and ECMS system synchronize block data, including the target data screening template, and extract the target data screening template data based on the record ID of that type, appending it to the node's own data screening template.

[0095] In this way, by assigning a template type identifier to the target data screening template, the target data screening template data can be distinguished from ordinary data, making it convenient for other nodes to obtain and record the data screening template.

[0096] Based on this, after S130 above, the data on-chain compliance control method provided in this application embodiment may further include:

[0097] Obtain the target data to be uploaded to the blockchain;

[0098] Based on the target data screening template, determine whether the target data contains at least the data corresponding to the target data module. The target data module is the module among N data modules whose corresponding data cannot be empty.

[0099] If the target data is determined to contain data corresponding to at least N data modules, the target data will be uploaded to the blockchain.

[0100] Here, blockchain nodes can obtain target data through RESTful APIs (Representational State Transfer Application Program Interface, RESTful API), database triggers, and other means. The target data to be uploaded to the chain can be business change records.

[0101] In this way, by screening the target data to be uploaded to the blockchain based on the target data screening template, and ensuring that the target data contains data corresponding to at least N data modules, the compliance of the uploaded data can be guaranteed.

[0102] In one alternative implementation, after determining whether the target data contains at least the data corresponding to the target data module based on the target data screening template, the aforementioned data on-chain compliance control method may further include:

[0103] If it is determined that the target data does not contain the data corresponding to the target data module, the target data will not be uploaded to the blockchain.

[0104] Here, if a blockchain node is screening target data and determines that the target data does not contain the data corresponding to the target data module, then the blockchain node can refuse to upload the data to the chain and notify the application layer of the abnormal status.

[0105] In a specific example, when the blockchain node integrated into the ECMS system is screening the record data, if it finds that a certain field in the template cannot be empty, but the record data is missing the content of that field, the blockchain node will refuse to store the data in the block data.

[0106] In this way, by screening the target data to be uploaded to the blockchain based on the target data screening template, and refusing to upload the target data to the blockchain if it is determined that the target data does not contain the data corresponding to the target data module, it is possible to prevent illegal data from being uploaded to the blockchain, thereby ensuring the compliance of the data uploaded to the blockchain.

[0107] In one alternative implementation, after generating the target data screening template in response to the template configuration input, the aforementioned data on-chain compliance control method may further include:

[0108] Assemble the target data screening template into the data screening component;

[0109] Accordingly, based on the target data screening template, it is determined whether the target data contains at least the data corresponding to the target data module, including:

[0110] Input the target data into the data screening component;

[0111] The data screening component determines whether the target data contains at least the data corresponding to the target data module.

[0112] Here, the target data screening template is assembled into the data screening component. The data screening component will use the data screening template as a basis to screen the throughput of on-chain data to determine whether the target data contains at least the data corresponding to the target data module. The data screening component can be, for example, an on-chain data compliance screener.

[0113] In a specific example, after the user completes the design of the data screening template, the blockchain node integrated by the DianShiChengJin system will assemble the data screening template belonging to its own system into the on-chain data compliance screener of this node. All data to be uploaded to the chain must pass the compliance test of the on-chain data compliance screener before it can be uploaded to the chain, and the on-chain data compliance screener performs the test based on the data screening template configured by the user.

[0114] In this way, the data screening component can determine whether the target data contains at least the data corresponding to the target data module, making it easier to use the target data screening template.

[0115] To better describe the overall solution, several specific examples are given based on the above embodiments.

[0116] For example, such as Figure 3 The flowchart shown illustrates the blockchain contract layer configuration method. This contract layer configuration method may include S301-S306, which will be explained in detail below.

[0117] S301, users design on-chain data screening templates in the template operation interface.

[0118] In a specific example, a blockchain network includes several blockchain nodes such as a gold-making system, an order system, a comprehensive resource system, and an engineering construction system. Each blockchain node is equipped with a template operation interface. Users can open the template operation interface and transfer the data module from the candidate area to the operation interface by clicking on the data module in the candidate area, thereby generating the target data screening template.

[0119] S302, the on-chain data screening template is assembled into the node's on-chain data screening component.

[0120] In a specific example, after the target data screening template is generated, the blockchain nodes integrated by the DianShiChengJin system will assemble the screening template belonging to their own system into the on-chain data screening component of their own node. All data to be uploaded to the chain must pass the compliance test of the screening component before it can be uploaded to the chain, and the basis for the screening component to perform the test is the generated target data screening template.

[0121] S303, the on-chain data screening template is used to record data on the blockchain.

[0122] In a specific example, in order to allow other nodes in the blockchain network to also obtain the full target data screening template, the blockchain node will put the target data screening template on the chain as record data and mark it with a special ID.

[0123] S304, all nodes synchronize and upload data to the blockchain to screen template data.

[0124] In a specific example, blockchain nodes deployed on the "Turning Stone into Gold" blockchain synchronize block data through the blockchain network. The block data includes records of the target data screening template type.

[0125] S305, the node obtains the on-chain data screening template data from the synchronized block data.

[0126] S306, the on-chain data screening component for nodes is equipped with an on-chain data screening template.

[0127] In a specific example, blockchain nodes deployed on the order system, integrated resource system, and ECMS system synchronize block data. The block data includes a target data screening template, and the target data screening template data is extracted based on the record ID of this type. The target data screening template data is then appended to the node's own data screening template.

[0128] like Figure 4 The flowchart shown is a blockchain data uploading method, which may include steps S401-S409, which will be explained in detail below.

[0129] S401, Business System A pushes a business change record to Node A via a RESTful API.

[0130] In a specific example, the ECMS system pushes a business change record to its integrated blockchain node via a RESTful API, such as "the single project in the ECMS system with the number 00010086 has been changed from the design stage to the construction stage".

[0131] S402, Node A uses the on-chain data screening component to screen this record.

[0132] In a specific example, the blockchain node integrated into the ECMS system matches the system identification code (ECMS), business identification code (single project), field code (process progress), operation code (modification), operation value (construction) templates in the on-chain data screening component to determine whether the record is compliant.

[0133] S403, screen whether the record conforms to the preset specifications of the on-chain data screening template.

[0134] S404, refuse to upload data to the blockchain and notify the application layer of the exception.

[0135] In a specific example, when the blockchain node integrated into the ECMS system screens the record data, if it finds that the field code in the template is not empty, but the record is missing the field code content, the blockchain node will refuse to store the record in the block data.

[0136] S405, upload this record data to the blockchain.

[0137] In a specific example, if a blockchain node integrated into the ECMS system screens a record and finds that the record contains at least the data corresponding to the data module in the data screening template, then the blockchain node will push the record to be stored in the block data.

[0138] S406, all nodes synchronize this on-chain data.

[0139] In a specific example, the blockchain nodes of the DianShiChengJin system and the ECMS system achieve full synchronization of data blocks through the blockchain network.

[0140] S407, Application B obtains the latest on-chain data through Node B.

[0141] In a specific example, the "Turning Stone into Gold" system retrieves the record from the integrated blockchain node via an API.

[0142] S408, Application B uses this change record to update the status of a certain field.

[0143] In a specific example, the "Turning Stone into Gold" system changed the stage of a single project in the original ECMS system (number 00010086) from the design stage to the construction stage.

[0144] Based on the above-mentioned data on-chain compliance control method, in one possible embodiment, such as Figure 5 As shown, a blockchain contract layer architecture system is disclosed, comprising: an operation module 501, an interface module 502, a screening module 503, and a storage module 504. The operation module 501 is used to configure data screening templates. Users can configure the business record data to be uploaded to the blockchain in the template operation interface according to business requirements, and the configuration results are saved to the data screening template.

[0145] Interface module 502 can include two sub-modules: a REST-style interface and a database trigger, which can be used to obtain business record data to be uploaded to the blockchain.

[0146] The screening module 503 may include two sub-modules: an on-chain data screening template and an on-chain data compliance screener. It can be used to perform compliance screening on the data to be uploaded to the chain and determine whether the data to be uploaded to the chain meets the preset data specifications.

[0147] Storage module 506 can be used to store the on-chain data screening template in the block data for uploading.

[0148] Therefore, by setting up a template operation interface, authorized users can visually create or modify data screening templates on their local node. By uploading these templates to the blockchain, all nodes within the blockchain can then screen the data on the chain based on this unified template. This allows for compliance control of on-chain data without requiring professional programming, preventing invalid or malicious data from being uploaded. This effectively reduces the development and maintenance costs required for compliance control of on-chain data, providing a secure, simple, self-maintaining, and self-synchronizing compliance control method.

[0164] In one embodiment, the device may further include:

[0169] In one embodiment, the upload module specifically includes:

[0170] The storage submodule is used to store the target data screening template in the block data.

[0171] The second upload submodule is used to upload block data to the blockchain.

[0172] In one embodiment, the target data screening template is assigned an identity identifier of the template type, so that other nodes in the blockchain can obtain the target data screening template based on the identity identifier of the template type.

[0173] Therefore, by setting up a template operation interface, authorized users can visually create or modify data screening templates on their local node. By uploading the data screening templates to the blockchain, all nodes in the blockchain can screen the on-chain data based on this unified data screening template. In this way, compliance control of on-chain data can be achieved without professional programming, preventing invalid or malicious data from being uploaded to the chain. This effectively reduces the development and maintenance costs required for compliance control of on-chain data, providing a secure, simple, self-maintaining, and self-synchronizing compliance control method.
