Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and features in the embodiments may be combined with each other without conflict.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a blockchain-based rule updating method provided by an embodiment of the present application, where the blockchain-based rule updating method is applied to a blockchain. As shown in FIG. 1 , the blockchain-based rule update method specifically includes steps S11 to S15. According to different requirements, the order of the steps in the schematic flowchart can be changed, and some can be omitted.

Step S11, in response to the rule update request initiated by the blockchain node, acquire rule data corresponding to the rule update request.

Exemplarily, when a user changes a preset rule on a terminal device, the blockchain node corresponding to the terminal device will generate a rule update request, and the rule update request includes the data that the user changes the preset rule, such as: rule data. Terminal devices may include mobile phones, tablet computers, desktop computers, laptop computers, handheld computers, notebook computers, ultra-mobile personal computers, netbooks, and other electronic devices. Changes to preset rules may include additions, deletions, and/or modifications .

Step S12, judging whether the rule data conforms to a preset rule policy.

The rule policy is preset. If the rule data corresponding to the rule update request conforms to the preset rule policy, the rule data is valid data, and the rule data previously stored in the blockchain can be updated; if the rule data corresponding to the rule update request does not conform to the preset rule data Rule policy, the rule data is invalid data, and the rule data previously stored in the blockchain cannot be updated.

Exemplarily, judging whether the rule data has verification information, when the verification information conforms to the preset rule policy, it is judged that the rule data conforms to the preset rule policy, and when the verification information does not conform to the preset rule policy, It is judged that the rule data does not conform to the preset rule policy.

Or, it is judged whether the submitter of the rule data has the permission to modify the rule, if the submitter of the rule data does not have the permission to modify the rule.

In some embodiments of the present application, the blockchain includes an endorsement node, and the judging whether the rule data conforms to a preset rule policy includes: acquiring verification information corresponding to the rule data; controlling the endorsement node to The verification information is verified to determine whether the rule data conforms to the preset rule policy.

The endorsement node may include a peer node in the Hyperledger Framework Fabric 1.0 architecture, and the endorsement node is used to determine whether the rule data conforms to a preset rule policy. Exemplarily, verification information corresponding to the rule data may be obtained, and the endorsement node may be controlled to verify the rule data according to the verification information, for example, to verify whether the rule data is legal.

In some embodiments of the present application, the verification information includes signature information and submitted user information, the controlling the endorsement node to verify the verification information, and judging whether the rule data complies with a preset rule policy includes: controlling The endorsement node verifies the signature information; if the signature information is verified as qualified, the endorsement node is controlled to verify the submitted user information. Perform verification; if the submitted user information is verified as qualified, it is determined that the rule data conforms to the preset rule policy; if the signature information is not verified as qualified or the submitted user information is not verified as qualified, it is determined that the rule data does not conform to the preset rule policy.

The signature information is used to verify whether the content of the rule data is legal, and the submitted user information is used to verify whether the user submitting the rule data has permission to modify the rule data.

Exemplarily, if the signature information is verified as qualified, it is determined that the rule data submitted by the user is legal; if the signature information is not verified as qualified, it is determined that the rule data submitted by the user is illegal, and if the rule data submitted by the user is determined to be valid. The data is legal, and the submitted user information corresponding to the user who submitted the rule data is verified; when the submitted user information is verified as qualified, it is determined that the user has the permission to modify the rule data, and the rule data is valid data; When the submitted user information is not verified as qualified, it is determined that the user does not have the permission to modify the rule data, and the rule data is invalid data.

Step S13, if the rule data conforms to a preset rule policy, determine the priority order corresponding to the rule data.

Different rule data have different priorities, and the rule data with a higher priority order is updated first, and then the rule data with a lower priority order is updated.

Exemplarily, the priority order corresponding to the acquired rule data may be determined by controlling the Order node. For example, the Order node can also be controlled to sort the rule data according to the priority order corresponding to the acquired rule data.

For example, as shown in FIG. 2, FIG. 2 is a schematic diagram of the framework of a blockchain network improved by an embodiment of the present application. The blockchain network may include multiple organizations, such as organization1, organization2, etc. Including multiple peer nodes, the peer node can be used to obtain the number of rules According to the verification, the rule data verified by the peer node can be sent to the sorting module through the preset channel, the sorting module can exchange data with the system channel, the sorting module can include multiple order nodes, and the order node can be used for sorting The rules data are sorted.

In some embodiments of the present application, the determining the priority order corresponding to the rule data includes: acquiring a request packet corresponding to the rule update request; acquiring packet segmentation corresponding to the request packet from a configuration tag library identifier; segment the request message based on the message segmentation identifier to obtain identification fragments; determine the priority order corresponding to the rule data according to the identification database and the identification fragments.

Exemplarily, a configuration tag library is preset, and the configuration tag library stores packet segmentation identifiers corresponding to various packet fragments, such as packet segmentation identifiers corresponding to identification fragments. The packet segmentation identifier is used to identify the location where the packet is to be segmented. Based on the position of the message segmentation identifier, the request message corresponding to the rule update request is segmented to obtain an identification segment, where the identification segment includes data information corresponding to the rule data.

The priority order corresponding to the rule data is determined according to the identification database and the identification segment. For example, an identification database may be preset, and the identification database includes mapping relationships corresponding to identification segments and priorities. For example, the priority order corresponding to identification segment A is first-level, and the priority order corresponding to identification segment B is second-level.

Step S14, verifying the rule data based on the priority order corresponding to the rule data and the blockchain verification mechanism.

Exemplarily, the control peer node corresponds to the rule data based on the blockchain verification mechanism The order of priority is to verify the correctness of the rule data. For example, the rule data with high priority order is verified first, and then the rule data with low priority order is verified. If the peer node verifies that the rule data is correct, the peer node is controlled to propagate the rule data to neighboring nodes. If the peer node verifies that a rule data is invalid, the control peer node discards the rule data, and no longer transfers the rule data to adjacent nodes, so as to avoid wasting computing resources.

The verification of the rule data by the peer node is carried out according to various verification agreements reached in advance based on the blockchain application, such as the format of the transaction, the data structure of the transaction, the grammatical structure of the format, the input and output, the correctness of the digital signature, etc.

Step S15, if the verification result of the rule data is correct, update the rule data stored in each block chain node in the block chain according to the rule data.

Exemplarily, if the verification result of all the rule data is correct, the control peer node puts the rule data in a transaction pool. When the previous block is confirmed, the controlling peer node will select transactions from the transaction pool to calculate the Merkle root in a certain priority order, and will verify the passed rule data according to the Merkle root to each area in the original blockchain. The rule data stored in the blockchain node is updated.

In some embodiments of the present application, the method further includes: acquiring an access blockchain request sent by a node, and acquiring node data corresponding to the node according to the access blockchain request; according to the node data , judging whether the node meets the standard for accessing the blockchain; if the node meets the standard for accessing the blockchain, the rule data stored in the node is updated according to the rule data.

Exemplarily, if a request for accessing the blockchain sent by a node is received, Obtain the node data corresponding to the node, and according to the node data, determine whether the node meets the standards for accessing the blockchain; if the node meets the standards for accessing the blockchain, according to the rules The data updates the rule data stored in the node.

For example, when a new node wants to access the blockchain network, it receives the application request sent by the node, and judges whether to join the node according to the application request. If it is determined not to join the node, the node information corresponding to the node is discarded; If it is determined to join the node, the node information of the node is verified. If the verification of the node information is qualified, the rule data corresponding to the blockchain network is obtained, and the rule data stored in the node is updated according to the rule data.

In some embodiments of the present application, the method further includes: if the node does not meet the criteria for accessing the blockchain, generating a corresponding rejection prompt according to a preset prompt rule.

By generating corresponding rejection prompts, users are prevented from continuing to repeatedly submit node-corresponding join requests, resulting in unnecessary waste of resources.

In some embodiments of the present application, the blockchain uses asymmetric encryption technology to encrypt transaction records, thereby ensuring the safety and reliability of rule data and improving the efficiency of rule update.

In some embodiments of the present application, the blockchain uses the time stamp technology to load time data every time the rule data is updated, thereby ensuring the plasticity and verifiability of the rule data, and improving the efficiency of the rule update.

The blockchain-based rule update method provided by the above embodiment obtains the rule data corresponding to the rule update request; and judges whether the rule data conforms to the preset rule policy; if the rule data conforms to the preset rule policy, Determine the priority order corresponding to the rule data; verify the rule data based on the priority order corresponding to the rule data and the blockchain verification mechanism; if the verification result of the rule data is correct, according to the rule data for each block in the blockchain The rule data stored in the chain node is updated. In this embodiment, the accuracy of the rule data update can be improved through multiple judgments. At the same time, by determining the priority order corresponding to the rule data and verifying the rule data based on the priority order, the rule data can be improved. The efficiency of updating, this embodiment can improve the efficiency and accuracy of updating rule data.
