Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The application provides an execution method of a blockchain crowdsourcing task, which can be applied to an execution system of the blockchain crowdsourcing task. The system for executing the blockchain crowdsourcing task comprises a plurality of client terminals and each blockchain node, wherein the plurality of client terminals at least comprise a first client terminal and a second client terminal, and the first client terminal and the second client terminal are communicated with the blockchain nodes through a network. Firstly, a first client terminal establishes a task contract according to a received task issuing request, and sends the task contract to each block link point for overall network consensus issuing, wherein the task contract comprises a task execution requirement; then, the second client terminal judges whether the user information meets the task execution requirement according to the task execution requirement and the user information in the user information contract corresponding to the second client terminal; if the user information meets the task execution requirement, the second client terminal adds the user identifier in the user information contract to the task contract and executes the task in the task contract; and finally, the second client terminal stores the task execution result to a storage layer of an execution system of the block chain crowdsourcing task, generates a corresponding storage pointer, adds the storage pointer to the task contract to obtain an updated task contract, and issues the updated task contract to each block chain node of the whole network. Alternatively, the plurality of client terminals may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server where the block link point is located may be implemented by an independent server or a server cluster formed by a plurality of servers.
Optionally, the consensus mechanism adopted for the consensus issuance among the block chain nodes may be a BFT (Byzantine Fault Tolerance algorithm), or a DPOS (cleared Proof of stamp, delegation rights certification algorithm) or a POW (Proof of Work, workload certification mechanism), and therefore, the embodiment of the present application is not limited.
An embodiment of the present application provides an execution method for a blockchain crowdsourcing task, as shown in fig. 1, specifically, taking an example that the method is applied to an execution system for the blockchain crowdsourcing task, a processing procedure is as follows:
step 101, a first client terminal creates a task contract according to a received task issuing request, and sends the task contract to each block link point for carrying out overall network consensus issuing, wherein the task contract comprises a task execution requirement.
In the implementation, a task publisher inputs a task publishing request through a human-computer interaction interface in a first client terminal, and the first client terminal writes a task execution requirement carried in the task publishing request into a task contract according to a preset contract creation rule according to the received task publishing request. Optionally, the task issuing request received by the first client terminal may further include: task originator ID (identity), task content, task initiation prepayment, task evaluation algorithm, and task reward algorithm. Therefore, the first client terminal can write all the information carried in the received request for issuing the task into the task contract. The embodiments of the present application are not limited. Meanwhile, the first client terminal generates a task ID corresponding to the task and identifies the task. Then, the first client terminal creates indexes such as a task executor IDlist, a task current state and a task execution result in the task contract. So that the second client terminal can update these metrics in the task contract during subsequent task executions. And finally, the first client terminal can send the created task contract to each block link point to carry out the consensus issuing of the whole network, and the task contract after the consensus is completed can be inquired by the user of the whole network.
Specifically, the task ID in the task contract may be a type of string identifier; the task content is a specific task received and executed by a task executor; the task initiator ID is a user identifier (which can be a type of character string identifier) obtained when a corresponding task initiating user registers user information; the task execution requirements comprise one or more of the upper limit of the number of task executors, the credibility requirements of the task executors, the activity requirements of the task executors, the historical times requirements of the executors for executing the tasks and the evaluation result requirements of the historical tasks. The task performer ID list is a user identifier obtained by the user participating in the task performance when registering user information. The task execution result comprises a specific task execution result and a corresponding storage pointer. The task executor ID list, the current task state, and the task execution result may be written into the task contract by the second client terminal in the subsequent task execution process to complete the update of the task contract. Optionally, the task initiator needs to submit a prepayment to ensure execution of the task contract, so as to avoid a null calculation phenomenon, and therefore, the task initiator can write the task prepayment amount into the task contract through the first client terminal. The mission advance payment may include a base award and an additional award.
As an optional implementation manner, when the execution system of the blockchain crowdsourcing task is used for the first time, a user issues a task or acquires a task to execute through a client terminal, and registration of user information is required to be performed first, which is described by taking the user as a task issuer as an example, and other cases are similar to the above, and specific processing steps are as follows:
step one, a first client terminal creates a user identifier according to a received registration request, wherein the registration request carries user information of a registered user.
In implementation, a task publisher inputs a registration request through a human-computer interaction interface of a first client terminal, the registration request carries user information of the task publisher, and the first client terminal generates a user identifier corresponding to a registered user. In particular, the user identification may be a type of string generated by the first client terminal.
And step two, the first client terminal creates a user information contract according to the user information and the user identification, and sends the user information contract to each block link point to carry out the total network consensus distribution.
In implementation, the first client terminal writes the user information carried in the registration request into a user information contract according to the user information and the user identifier in the registration request and a preset contract creation rule. Optionally, the user information may include: the method includes the steps of obtaining user basic information, user reputation, user activity, user skill, user bearable role and task list, and the embodiment of the application is not limited. Therefore, the first client terminal can write all of the above-mentioned user information in the user information contract. And then, the first client terminal sends the created user information contract to each block link point for carrying out the consensus distribution of the whole network. After the consensus is completed, the user information is written into the block chain, and an execution system of the block chain crowdsourcing task can inquire the user information through the user information contract.
Specifically, in the user information contract, the user basic information includes, for example, the profession, the academic calendar, and the like of the registered user; the user credibility is the current credibility obtained by the user aiming at the historical execution condition of the task; the user skills comprise professional skills (such as programming capability, data processing capability and the like) possessed by the user, and are convenient to match with the executed task types; the user activity is the activity of the execution system of the user participating in the blockchain crowdsourcing task, and may include: task delay and bidding times; the user assumed roles include task performers, task publishers, and task verifiers (also referred to as verification nodes). The task list in the user information contract may include a history execution record of the registered user for the type of task, where the history execution record includes a task ID and a task contract address corresponding to the type of task.
Optionally, when each user finishes user information registration, the client terminal of each user may correspondingly generate a key pair (a public key and a private key) of the user, when the task publisher needs to define task content as a specified target task performer to perform, the first client terminal corresponding to the task publisher may encrypt task content in the task contract through the public key of the target task performer, and the second client terminal decrypts the obtained task content through the private key of the target task performer to obtain specific task content. Similarly, the second client terminal can sign the completed task execution result through the private key of the target task executor, so that the task issuer can know the task executor executing the task.
And 102, the second client terminal judges whether the user information meets the task execution requirement or not according to the task execution requirement and the user information in the user information contract corresponding to the second client terminal.
In the implementation, a task executor applies for obtaining a task to be completed, which is issued by an execution system of the block chain crowdsourcing task, through a second client terminal, and the second client terminal judges whether the user information meets the task execution requirement or not according to the task execution requirement in a task contract corresponding to the task and the user information in a user information contract corresponding to the second client terminal.
As an optional implementation manner, the task execution requirement includes at least one information evaluation criterion in the user information, and the second client terminal determines whether the user information meets the information evaluation criterion in the task execution requirement according to the information evaluation criterion and the user information in the user information contract corresponding to the second client terminal, where the specific processing procedure is as follows:
judging at least one item of user information in a user information contract according to an information evaluation standard in a task execution requirement, wherein the user information comprises user basic information, user credit, user skill and user activity; and if the user information meets all information evaluation criteria in the task execution requirement, determining that the user corresponding to the user information contract meets the task execution requirement.
For example, the information evaluation index included in the task execution requirement in the task contract is the upper limit of the number of task executors: and 5, if the user reputation is greater than or equal to 80 minutes and the user skill has Java programming capability, the second client terminal compares the information evaluation index in the task contract with the user information in the user information contract of the second client terminal to judge, and if the user reputation and the user skill in the user information corresponding to the second client terminal both meet the task execution requirement in the task contract and the number of task executors in the task contract does not reach the upper limit of the number, the user corresponding to the user information contract is judged to meet the task execution requirement.
And 103, if the user information meets the task execution requirement, the second client terminal adds the user identifier in the user information contract to the task contract and executes the task in the task contract.
In implementation, if the user information in the user information contract corresponding to the second client terminal meets all the information evaluation indexes in the task execution requirement, the second client terminal may add the user identification (user ID) included in the user information contract to the task executor IDlist of the task contract and then correspondingly execute the task in the task contract.
Optionally, if the user corresponding to the second client terminal meets the task execution requirement, the second client terminal may deposit the token as a deposit, and then collect the task for execution.
And 104, the second client terminal stores the task execution result to a storage layer of an execution system of the block chain crowdsourcing task, generates a corresponding storage pointer, adds the storage pointer to the task contract to obtain an updated task contract, and issues the updated task contract to each block chain node of the whole network.
In implementation, after the second client terminal completes the tasks in the task contract, the task execution result is stored in the storage layer of the block chain crowdsourcing task execution system, a corresponding storage pointer is generated, the storage pointer is added to the task contract, and the updated task contract is published at each block chain node of the whole network.
As an optional implementation manner, the second client terminal may obtain a task execution result according to a storage pointer in the task contract, and evaluate the task execution result according to a task evaluation algorithm in the task contract to obtain a task evaluation result; and then, the second client terminal adds the task evaluation result to the task contract and issues the updated task contract to each block chain node of the whole network.
In implementation, the second client terminal may obtain a corresponding task execution result according to a storage pointer in the task contract, and evaluate the task execution result according to a task evaluation algorithm pre-established in the task contract to obtain a task evaluation result, where the task evaluation result is divided into two types (good or bad). And then, the second client terminal adds the obtained task evaluation result to a task contract and issues the updated task contract to each block chain node of the whole network. Optionally, a homomorphic encryption technology is adopted in a task evaluation algorithm in the task contract, so that it is ensured that a verification node (a task verifier) can still evaluate a task execution result without knowing specific contents of the task, and the verification node may be a second client terminal corresponding to a task issuer or a client terminal corresponding to another user, so that the embodiment of the present application is not limited.
As an optional implementation manner, the user information contract further includes a task list, and the second client terminal updates the user information in the user information contract according to a preset updating algorithm; and the second client terminal writes the address of the task contract corresponding to the acquired target task into the task list and issues the updated user information contract to each block link node of the whole network.
In implementation, after the second client terminal completes the executed task, the second client terminal may update the user information in the user information contract according to a preset update algorithm, for example, the second client terminal updates the current reputation of the user in the user information contract according to the preset reputation update algorithm and the lowest reputation of the type of task in the whole network, and specifically, the user j corresponding to the second client terminal updates the current reputation of the type of task K for the current reputation of the type of task KDegree of credit of beta j,k ，H K Lowest reputation value, β, for the execution of this type of task j,k A typical update function of (a) is as follows:
and meanwhile, the second client terminal writes the acquired task ID corresponding to the target task and the address of the task contract into the task execution list to complete the task recording of the executed task. And finally, the second client terminal issues the updated user information contract to each block chain node of the whole network.
As an optional implementation manner, the second client terminal generates the reward of the second client terminal according to the task evaluation result and the reward algorithm corresponding to the second client terminal in the task contract; the second client terminal then obtains the reward.
Optionally, the reward includes a basic reward and an additional reward, if the task evaluation result of the second client terminal in the second client terminal query task contract is good, a corresponding reward transaction is created, the corresponding reward transaction is stored in the block chain and sent to each node of the block chain for global consensus distribution, wherein the generated reward includes the basic reward and the additional reward, and if the task evaluation result of the second client terminal in the third client terminal query task contract is poor, the corresponding generated reward is only the basic reward.
