In order to better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Fig. 1 is a flowchart illustrating a method for constructing a blockchain system according to an embodiment of the present invention, where the blockchain system includes a plurality of nodes, each node is configured with a task operation table and a statistical information table, and the task operation table is configured in a way that no operation is recorded, as shown in fig. 1, the method for constructing the blockchain system includes the following steps:
s101, receiving a task request initiated by any node, so that a production node in the blockchain system produces a block according to the task request to perform whole network synchronization.
That is, a task request initiated by any node in the blockchain system is received, so that a production node in the blockchain system produces a block according to the task request for network-wide synchronization.
The method includes that a production node produces blocks according to task requests, for example, after receiving a task request, the production node caches the task request, and packs the task requests of a previous block time line and a current time after a time difference between the previous block time line and the current time reaches a preset time to form a block; or after receiving the task requests, the production node caches the task requests, and packs the task requests of the previous block time line and the current time after the number of the task requests of the previous block time line and the current time reaches a preset number to form a block.
The task request mode can be various, for example, a voting request, a block chain competitive project win-loss statistical request, a transaction frequency statistical request, and the like; therefore, the form of the task request is not limited herein.
S102, after the project corresponding to the task request is confirmed, receiving an operation request initiated by each node aiming at the project through the task operation table, so that the production node can operate and count the task of the project by inquiring the statistical information table according to the operation request, and discarding the operation request after finishing one operation request.
That is, after an item corresponding to a task request is confirmed by the blockchain system, the nodes in the blockchain are allowed to perform an operation corresponding to the item, and an operation request initiated by each node in the blockchain for the item through the task operation table is received.
For example, after the production nodes pack the blocks and broadcast, acquiring the number of online nodes in the current block chain system, counting the number of nodes which synchronize the blocks after the nodes in the block chain synchronize the blocks, and judging whether the ratio of the counted number of nodes which synchronize the blocks to the number of online nodes in the current block chain system reaches a preset threshold value, if so, judging that the item corresponding to the task request is confirmed; or after the block is packaged and broadcasted by the production node, counting the number of the nodes which synchronize the block, and judging whether the ratio of the number of the nodes which synchronize the block to the total number of the nodes in the block chain system reaches a preset threshold value, if so, judging that the project corresponding to the task request is confirmed.
It should be noted that the task operation table configures the content specified in the assigned configuration task operation table in a manner of not recording operations, as the content that needs to be discarded after the operation request is operated and counted by the production node.
As an example, when the blockchain system is a voting blockchain system, the task operation table includes the ID of the voted object and the voting item task ID, and the statistics table includes the statistics source, the statistics object, and the statistics type. Taking a practical case as an example, in the voting operation, defining the content format corresponding to the operation request in the task operation table as select (pid, oid); wherein select is a function name, oid indicates an ID corresponding to the elected object, and pid indicates an ID corresponding to the voting project task; then the operation request select (pid, oid) is discarded after the production node operates and counts the operation requests according to the task operation table.
Receiving an operation request initiated by each node for the item through the task operation table means that each node in the block chain searches an operation format associated with the item corresponding to the task request in the task operation table, and initiates the operation request to the block chain system according to the operation format.
As an example, after an item corresponding to a task request is confirmed by the blockchain system, the user node finds that an operation format associated with the item corresponding to the task request is select (pid, oid) through the task operation table, and then the user node initiates an operation request to the blockchain system according to the operation format; where select is the function name, oid indicates the ID corresponding to the object being voted, and pid indicates the ID corresponding to the voting project task.
For example, after receiving the operation request, the production node establishes a project statistic item of the project corresponding to the operation request in the statistic information table according to the operation request, and operates and counts the project statistic item of the corresponding project according to the operation request.
As an example, in a voting operation, a user node sends an operation request select (pid, oid), after receiving the operation request, a production node establishes a project statistic item corresponding to the pid in a statistic information table according to the pid in the operation request, and establishes oid corresponding sub-items in the project statistic item corresponding to the pid, so as to perform respective statistics on election objects corresponding to different projects according to the operation request; where select is the function name, oid indicates the ID corresponding to the object being voted, and pid indicates the ID corresponding to the voting project task.
S103, judging whether the block production authority time limit of the production node is reached.
For example, whether the time difference from the previous block time line to the current time reaches a preset time threshold value is judged, if yes, the block production right time limit of the production node is judged to have reached, or whether the number of the operation requests from the previous block time line to the current time reaches a preset number predicted value is judged, and if yes, the block production right time limit of the production node is judged to have reached.
S104, if the block production right time limit of the production node is reached, the statistical results are packed into blocks after the production node performs accumulation operation on the statistical results, and the whole network broadcasting is carried out so as to synchronize the statistical result information at each node.
That is, when the block production authority limit of the production node is reached, the statistical result is accumulated by the production node and packed into a block, and the block is broadcast all over the network so that each node in the block chain synchronizes the statistical result information.
In summary, according to the method for constructing a blockchain system in an embodiment of the present invention, the blockchain system includes a plurality of nodes, each node is configured with a task operation table and a statistical information table, wherein the task operation table is configured in a way of not recording operations, and the method includes the following steps: firstly, receiving a task request initiated by any node, so that a production node in a block chain system produces a block according to the task request to carry out full-network synchronization; then, after the project corresponding to the task request is confirmed, receiving an operation request initiated by each node aiming at the project through a task operation table, so that the production node can operate and count the task of the project by inquiring a statistical information table according to the operation request, and discarding the operation request after finishing one operation request; then, judging whether the block production power time limit of the production node is reached; then, if the block production right time limit of the production node is reached, the statistical results are packed into blocks after the production node performs accumulation operation on the statistical results, and the whole network broadcasting is carried out, so that the statistical result information is synchronized at each node; therefore, the operation and the statistics of the key information in the operation request are realized, and the operation request is discarded after the operation and the statistics, so that the storage load of the nodes in the block chain system is reduced, and the normal operation of the nodes in the block chain system is ensured.
Fig. 2 is a flow chart illustrating a method for constructing a blockchain system according to another embodiment of the present invention, as shown in fig. 2, the method for constructing a blockchain system includes the following steps:
s201, a task operation table and a statistical information table are configured for each node in the block chain system.
The task operation table is configured in a mode of not recording operation, and comprises the ID of the selected object and the ID of the voting project task; the statistical information table comprises statistical sources, statistical objects and statistical types, and the statistical information table is expressed as the operation of performing accumulation statistics on selected objects in the task operation table; that is, the statistical information table is used for performing cumulative statistics on the selected objects in the task operation table.
S202, the task operation table and the statistical information table are loaded through the initial node of the blockchain system, so that after the created block is created at the initial node, other nodes in the blockchain system synchronize the task operation table and the statistical information table through synchronizing the created block.
That is, the initial node of the blockchain system loads the task operation table and the statistics table, so that after the initial node creates the created block, other nodes connected to the blockchain system can synchronize the task operation table and the statistics table by synchronizing the created block, and perform configuration synchronization of the task operation table and the statistics table.
S203, receiving a task request initiated by any node, so that a production node in the blockchain system produces a block according to the task request to perform whole network synchronization.
And S204, after the project corresponding to the task request is confirmed, receiving an operation request initiated by each node aiming at the project through the task operation table.
S205, the production node inquires the statistical information table according to the operation request, and judges whether the statistical information table has the content item which is subjected to accumulation statistics aiming at the elected object.
That is, after receiving the operation request, the production node queries the statistical information table according to the operation request, and determines whether the content item accumulated and counted for the elected object exists in the statistical information table, so as to determine whether the operation request is an operation requiring statistics.
S206, when the judgment result is yes, searching the election task accumulation table locally cached by the node to judge whether the content item of the voting item task exists in the election task accumulation table.
That is, after the production node determines that the operation request is an operation that needs to be counted, the election task accumulation table locally cached by the node is searched to determine whether the content item of the voting item task exists in the election task accumulation table.
And when the judgment result is negative, establishing a corresponding content item for the voting project task so as to count the voting project task.
The election task accumulation table of the local cache refers to an election task accumulation table for counting election tasks generated by a current block in the block production process by a production node, and is used for counting voting task items generated by the current block; and the voting task items are used as the basis for the subsequent production nodes to gather the voting task items.
S207, judging whether the content items of the voting project task have the sub-items of the elected objects or not when the judgment result is yes; if yes, go to step S208; if not, step S209 is executed.
That is, when the production node determines that the voting task accumulation table cached locally at the node has the content item of the voting task, it determines whether the content item of the voting task has the sub-item of the elected object according to the elected object included in the operation request.
And S208, adding 1 to the statistical value of the selected object.
S209, creating a sub item of the selected object, and setting the statistic value of the selected object to be 1.
S210, judging whether the block production power time limit of the production node is reached.
S211, if the block production right time limit of the production node is reached, the statistical results are packed into blocks after the production node performs accumulation operation on the statistical results, and the whole network broadcasting is carried out, so that the statistical result information is synchronized at each node.
The step of performing accumulation operation on the statistical result by the production node and then packaging the statistical result into a block refers to accumulating the election task accumulation table of the current local cache of the production node and the historical election task statistical information of the system to obtain complete statistical information and packaging the complete statistical information into the block.
As an example, the election task accumulation table (LT) is cached locally at the production node, and when the block production right time limit of the production node arrives, the production node acquires the system task table (T) in the block chain system; and initiating a cumulative (LT) operation to accumulate the statistic item in the LT into T so as to achieve complete statistics of the statistic result of the election task in the block chain.
In summary, according to the method for constructing a blockchain system in the embodiment of the present invention, first, a task operation table and a statistical information table are configured for each node in the blockchain system; then, loading the task operation table and the statistical information table through an initial node of the blockchain system, so that other nodes in the blockchain system synchronize the task operation table and the statistical information table through synchronizing the created blocks after the created blocks are created at the initial node; then, receiving a task request initiated by any node, so that a production node in the blockchain system produces a block according to the task request to perform full-network synchronization; then, after the project corresponding to the task request is confirmed, receiving an operation request initiated by each node aiming at the project through a task operation table; then, the production node inquires a statistical information table according to the operation request and judges whether a content item for performing accumulation statistics on the elected object exists in the statistical information table or not; then, when the judgment result is yes, searching an election task accumulation table locally cached by the node to judge whether the content item of the voting item task exists in the election task accumulation table or not; then, when the judgment result is yes, judging whether the sub item of the elected object exists in the content items of the voting project task; if yes, adding 1 to the statistical value of the selected object; if not, creating a sub item of the selected object, and setting the statistical value of the selected object as 1; then, judging whether the block production power time limit of the production node is reached; then, if the block production right time limit of the production node is reached, the statistical results are packed into blocks after the production node performs accumulation operation on the statistical results, and the whole network broadcasting is carried out so as to synchronize the statistical result information at each node; therefore, the operation and the statistics of the key information in the operation request are realized, and the operation request is discarded after the operation and the statistics, so that the storage load of the nodes in the block chain system is reduced, and the normal operation of the nodes in the block chain system is ensured.
