The method described in fig. 2 is applied to a blockchain system, which may include a plurality of authorized nodes. As shown in fig. 2, the method may include the operations of:
101. the first authorized node selects one authorized node from the rest authorized nodes except the first authorized node as a proxy node.
In the embodiment of the invention, the first authorization node is an authorization node which has the accounting authority last time in all the authorization nodes included in the blockchain system. It should be noted that, when the building of the blockchain system is completed, the first authorization node is an initial node, and when the blockchain system is subsequently applied to tableware circulation information management, the first authorization node is an authorization node having the last accounting authority among all authorization nodes included in the blockchain system, and the authorization node having the last accounting authority may be an originating node or an authorization node having the last accounting authority determined by a voting mechanism.
102. And the agent node collects the voting results of each authorization node in the rest authorization nodes except the agent node in all the authorization nodes, counts all the collected voting results to obtain the authorization node with the highest vote number, and serves as the second authorization node with the accounting authority at this time.
In the embodiment of the present invention, it should be noted that the agent node itself may or may not participate in the voting. If the agent node participates in voting, when the authorized node with the highest vote count is counted, the voting result of the agent node itself needs to be considered in addition to counting the collected voting result of each authorized node in other authorized nodes. It should be further noted that the agent node may collect the voting result of each authorized node in the remaining authorized nodes except the agent node in all the authorized nodes, or may collect only the voting result of each authorized node having the voting right in the remaining authorized nodes except the agent node in all the authorized nodes.
In the embodiment of the invention, the voting result of the authorization node is used for representing the authorization node which is selected by the authorization node at this time and has the accounting authority, and when the authorization node participates in voting, the method can select a preset number of authorization nodes for voting according to a preset requirement, the preset number can be one or a plurality of authorization nodes, preferably, the number of the authorization nodes selected by each authorization node during voting can be specifically determined by the number of the authorization nodes with the accounting authority actually required at this time, further optionally, the number of the authorization nodes with the accounting authority actually required at this time can be specifically determined by the data volume of the tableware circulation information to be packaged, and the more the data volume of the tableware circulation information to be packaged, the more the number of the authorization nodes with the accounting authority which are actually required at this time, and the embodiment of the invention is not limited. Therefore, the mode of determining the number of the actually required authorized nodes with the accounting authority according to the data volume of the tableware circulation information to be packaged is favorable for improving the efficiency of packaging the tableware circulation information to be packaged into blocks and adding the blocks to the block chain, the mode of setting the voting number is favorable for improving the validity of the voting result of the authorized nodes, and the occurrence of malicious voting is reduced.
In the embodiment of the present invention, after counting all voting results to obtain the authorized node with the highest vote number, the proxy node may further perform the following operations:
the proxy node broadcasts the related information of the second authorization node to all authorization nodes except the proxy node, so that the subsequent authorization nodes except the proxy node verify the identity of the second authorization node when receiving the block broadcast by the second authorization node.
Each authorization node has a node identifier uniquely corresponding to the node identifier, and may also have an IP address and/or a port number and/or a public key and/or a private key uniquely corresponding to the node identifier, and the related information of the second authorization node may include at least one of the node identifier of the second authorization node, the IP address of the second authorization node, the public key of the second authorization node, and the port number of the second authorization node, which is not limited in the embodiment of the present invention.
As an optional implementation manner, the counting, by the agent node, all the collected voting results to obtain an authorized node with the highest vote number, and as a second authorized node having the current accounting right, may include:
the agent node counts all the collected voting results to obtain all the voted authorization nodes to be voted and the vote number of each authorization node to be voted;
the proxy node determines a target authorization node to be selected with the highest ticket number according to the ticket number of each authorization node to be selected;
when the number of the target authorization nodes to be selected is one, the proxy node determines the target authorization nodes to be selected as second authorization nodes with the accounting authority at this time;
when the number of the target nodes to be authorized is at least two, the agent node selects one authorization node from all the target nodes to be authorized as a second authorization node with the accounting authority;
when the number of the target nodes to be authorized is at least two, the second authorized node is one of the authorized nodes randomly selected by the agent node from all the target nodes to be authorized; or the second authorized node is one authorized node which is selected by the agent node from all target authorized nodes to be selected and meets the preset node condition.
Optionally, each authorization node to be selected corresponds to a corresponding node parameter, and the real-time node parameter may be one or a combination of multiple types, such as response speed of the authorization node, total number of historical votes of the authorization node, total number of historical effective votes of the authorization node, and computing power of the authorization node.
Still further optionally, the counting, by the agent node, all the collected voting results to obtain all the voting authorization nodes to be voted and the number of votes of each authorization node to be voted may include:
and the agent node filters invalid voting results from all the collected voting results to obtain valid voting results, and determines all the voted authorization nodes to be voted and the vote number of each authorization node to be voted according to all the valid voting results.
The invalid voting result includes a voting result that the voting result is empty, a voting result that the number of the selected authorization nodes does not reach the preset number, or a voting result that a duplicate authorization node exists in the selected authorization nodes. Therefore, the mode of filtering the invalid voting results in the process of determining the second authorization node according to the voting mechanism is beneficial to reducing the processing resources required by the agent node for counting the voting results, and can improve the counting efficiency, and in addition, the fairness for selecting the authorization node with the accounting authority at this time can be further improved.
Optionally, after the authorization node generates the voting result, the authorization node may further generate a state identifier corresponding to the voting result according to whether the specific content of the voting result and the specific content of the voting result satisfy a preset content condition, and bear the state identifier on the voting result, so as to obtain the voting result required to be collected by the agent node. The status identifier is used for indicating whether the voting result is valid, if the content of the voting result meets the preset content condition, the status identifier is used for indicating that the voting result is valid, and if the content of the voting result does not meet the preset content condition, the status identifier is used for indicating that the voting result is invalid. Therefore, the mode of bearing the state identifier in the voting result enables the agent node to directly identify whether the voting result is an invalid voting result according to the state identifier borne by the voting result after receiving the voting result, and the specific content of the voting result does not need to be further analyzed, so that the efficiency of filtering the invalid voting result by the agent node is improved, and the efficiency of obtaining the second authorization result with the highest vote number through statistics is improved.
It should be noted that, when the number of the authorization nodes with the accounting authority required this time is multiple, after counting the number of votes of each authorization node to be selected, the proxy node may sort all authorization nodes to be selected according to the order of the number of votes from high to low, and select the authorization nodes to be selected that are N bits before the sorting as the multiple second authorization nodes with the accounting authority, where N is the number of the authorization nodes with the accounting authority required this time.
