In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
An embodiment of the present invention provides a distributed task processing method based on a block chain, and as shown in fig. 1, the distributed task processing method based on the block chain includes:
step S1: the method comprises the steps of acquiring a task to be issued uploaded to a task issuing block chain node by a task issuer, generating task information according to the task to be issued, and issuing the task information to a block chain for a distributed execution block chain link node to acquire the task information. Specifically, the task information includes various tasks to be executed.
Step S2: and generating a comprehensive report according to each task execution report acquired from the block chain, wherein the task execution report is generated by acquiring the information of the task to be executed from the task information for the distributed execution block chain node, executing the corresponding task to be executed according to the information of the task to be executed, generating and sending the task to the block chain. Specifically, the integrated report is the completion of the entire task issued by the task issuer.
Through the steps S1 to S2, the distributed task processing method based on the blockchain according to the embodiment of the present invention completes the task distribution and the task acquisition in the blockchain, thereby implementing decentralized distributed processing of the task, improving the efficiency and the safety of the task distribution and execution, and monitoring the process from the task distribution to the task execution by performing evidence storage and analysis on the behavior of each task through the blockchain to generate a comprehensive report.
The following describes in detail a distributed task processing method based on a block chain according to an embodiment of the present invention with reference to specific examples.
In a preferred embodiment, as shown in fig. 2, the step S1 above obtaining the task to be published uploaded to the task publishing block link node by the task publisher, and generating the task information according to the task to be published specifically includes:
step S11: and generating the information abstract by adopting a digital abstract algorithm according to the task to be issued. Specifically, the digital digest algorithm is used for encrypting the task to be issued by utilizing the one-way irreversible characteristic, so that the information digest is generated, and the safety of the task to be issued is further improved.
Step S12: and acquiring a private key of the task publisher, and signing the information abstract by using the private key to generate an information signature value. Specifically, the digest information is signed by a private key, so that a task executor can conveniently verify through a corresponding public key, and the safety of the task to be issued is further improved.
Step S13: and generating task information according to the task to be issued, the information abstract and the information signature value. In practical application, after the task information is distributed on the block chain, the task executing party can acquire the tasks to be executed according to the task information, so that the task issuing efficiency is improved.
In a preferred embodiment, as shown in fig. 3, the obtaining, by the distributed execution block chain node in step S2, information of a task to be executed from task information, and executing a corresponding task to be executed according to the information of the task to be executed to generate a task execution report specifically includes:
step S21: and acquiring a task list in the task information to be executed according to a preset screening condition. In practical applications, each task executor may need to execute a plurality of tasks issued by different task issuers, and therefore, needs to select a task to be executed currently, where the preset screening condition is an execution order of each task information in the task list, for example, the earliest issued task information is obtained by using the time of task issuance as the preset screening condition.
Step S22: and judging whether the task list is empty or not. Specifically, before executing the task, it is first determined whether there is a task that needs to be executed, and if the task list is empty, it indicates that there is no task to be executed, and the task execution is ended.
Step S23: and when the task list is not empty, obtaining the tasks to be executed from the task list according to the list sequence. In practical application, when there is a task to be executed in the task list, the first task is obtained from the task list according to the sequence, and information such as task information, an information signature value, a publisher public key and the like is obtained through analysis.
Step S24: and executing the task to be executed and generating a task execution report. In practical applications, the task execution report includes public key and private key information of the task performer, and process and result information of performing the task, such as time information and completion information of performing the task.

step S25: and judging whether the task to be executed needs to be checked or not according to a preset task checking requirement. In practical application, the task to be executed received by the task performer may include an illegal task, so that the task to be executed may be verified according to a preset task verification requirement of the task performer, for example, when the illegal task performed by the task performer may cause serious consequences, before the task is performed, task verification may be set, and the safety of the task performed by the task performer is ensured through the task verification. When the preset task verification requirement of the task performer is that task verification is not required, step S24 is performed.
Step S26: and when the task to be executed needs to be verified, acquiring a public key of the task publisher, and performing information verification on the task to be executed according to the public key and the task information corresponding to the task to be executed to generate an information verification result. In practical applications, the information verification is to perform digital signature verification on the information digest and the information signature value in the task information through the public key of the task issuer, and when the information verification result is that the verification is passed, step S24 is performed.
Step S27: and when the information verification result is that the verification is failed, judging whether the task to be executed is the last task in the sequence in the task list. In practical application, when the information check is not passed, it is determined that the task to be executed is an illegal task and is not executed, and it is determined whether the task to be executed is the last task in the task list, if no other task to be executed exists, the task execution is finished, and when the task to be executed is not the last task in the task list, step S23 is executed to obtain the next task to be executed to continue execution.
In a preferred embodiment, as shown in fig. 4, the generating a comprehensive report according to the task execution reports obtained from the blockchain in step S2 includes:
step S31: and acquiring a task execution report corresponding to the preset number according to the preset number of the task to be issued, and generating a task execution report list. In practical application, when a task publisher publishes a task, a corresponding task preset number, such as an ID number, may be provided, and according to the preset number, a task execution report corresponding to the number may be obtained, so as to obtain a task execution report list.
Step S32: and judging whether the task execution report list is empty or not. In practical application, before analyzing the task execution situation, it is first determined whether there is a task execution report in the task execution report list, and when there is no task execution report, the task report analysis is finished.
Step S33: and when the task execution report list is not empty, acquiring the task execution report from the task execution report list according to the list sequence. In practical applications, the first task execution report is sequentially obtained from the task execution report list according to a sequence for analysis, for example, the sequence may be performed according to the generation time of the task execution report.
Step S34: and carrying out report analysis on the task execution report to obtain a report analysis result. In practical applications, the analysis result includes report information, a report information signature value, a report publisher public key, a task execution result, and the like.
Step S35: and generating a comprehensive report according to the report analysis result. In practical application, the comprehensive report is used for reflecting the task issuing condition of each task publisher and the task execution condition of the task performer, so that the monitoring of the whole distributed task processing process is realized.
In a preferred embodiment, as shown in fig. 4, after the step S34 is executed and before the step S35 is executed, the method for processing distributed tasks based on blockchains further includes:
step S36: and judging whether the task execution report needs to be checked or not according to a preset execution report checking requirement. In practical application, the task execution report may include part of illegal information or error information, and therefore the task execution report may be verified according to a preset task execution report verification requirement of a task publisher, before the task execution report is analyzed, the task execution report may be set for verification, and safety of a task analysis process is guaranteed through verification. When the preset task execution report verification requirement is that verification is not required, step S35 is executed.
Step S37: and when the task execution report needs to be verified, acquiring a public key of the task publisher, and performing information verification on the task execution report according to the public key and the task information corresponding to the task execution report to generate an information verification result. In practical applications, the information verification is to perform digital signature verification through the acquired report information, the report information signature value, the task performer public key, and the like, and when the information verification result is that the verification is passed, step S35 is performed.
Step S38: and when the information verification result is that the verification is failed, judging whether the task execution report is the last task execution report sequenced in the task execution report list. In practical applications, when the information check fails, it indicates that the content of the task execution report includes illegal information or error information, and it is not analyzed, and determines whether the task execution report is the task execution report ranked last in the task execution report list, if no other task execution report exists, the task report analysis is finished, and when the task execution report is not the task execution report ranked last in the task execution report list, step S33 is executed, and the next task execution report is obtained to continue the analysis.
Through the steps S1 to S2, the distributed task processing method based on the blockchain according to the embodiment of the present invention completes the decentralized task distributed processing in the blockchain by issuing the task and acquiring the task, thereby improving the efficiency and safety of task issuing and execution, and generating a comprehensive report by performing evidence storage and analysis on the behavior of each task through the blockchain, thereby monitoring the process from issuing the entire task to executing the task, and effectively preventing the task from being lost by checking the task executing and task executing report, thereby further ensuring the safety of the entire task processing process.
