Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of one or more embodiments of the specification, as detailed in the claims which follow.
It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the methods may include more or less steps than those described herein. Moreover, a single step described in this specification may be divided into multiple steps for description in other embodiments; however, in other embodiments, multiple steps described in this specification may be combined into a single step for description.
The appointment is a thing which is achieved by people and people or people and a third-party organization together through a commodity and needs to be completed within a preset time. With the development of internet technology, more and more transactions can be implemented online based on the internet. At present, the application of assisting users or users and organizations to contract and perform by means of the internet is lacked.
In view of this, one or more embodiments of the present specification provide a data processing method, which assists a user in fulfilling an agreement based on internet technology and executes a reward for a performance meeting the agreement, thereby encouraging the performance of the user.
Fig. 1 illustrates a data processing method provided in an exemplary embodiment of the present specification, which is applied to a provisioning platform. The provisioning platform may include a service device for providing services for provisioning between users, between users and organizations, or between organizations, as shown in fig. 1, the method includes:
and 102, receiving a participation application for a target appointment task sent by a target user client.
The appointment tasks described in the embodiments of the present specification include contents such as an appointment of a transaction to be completed among appointment participants, an appointment of a time to complete a specific transaction, or an appointment of an achievement level to be achieved by completing a specific transaction, and the present specification does not limit the contents and the specific representation forms of the appointment tasks. From actual business scenes, those skilled in the art can develop various contents of appointed tasks, such as life tasks of appointed watching movies and gathering meals among users, or exercise tasks of body building and running, or work tasks established from work contents.
Moreover, the specification does not limit the specific manner in which the user obtains the appointment task. For example, any user may send the content of the engagement task to the engagement platform, and other users of the engagement platform may participate in engagement with the engagement task based on the content of the engagement task displayed by the engagement platform. Alternatively, any user may generate the appointment content for participating in a specific appointment task by a specific user at the client, and send the generated appointment content to the appointment platform, so as to generate a fulfillment contract based on the appointment platform.
Based on the specific mode for acquiring the appointed task, the target user client can acquire the target appointed task; after determining to participate in engagement of the target engagement task, the target user can send a participation application for the target engagement task to the engagement platform based on the target user client.
The engagement platform is used as an observer of the target user who participates in engagement of the target engagement mission and fulfills the target engagement mission, and an executor which conducts the performance reward on the target user when the actual performance behavior data of the target user meets the preset performance conditions at least generates the performance contract for the target engagement mission with the target user.
The fulfillment conditions may include threshold conditions such as a completion threshold, a completion time threshold, and a completion location range threshold for the target appointment task. The fulfillment conditions may be included in the target engagement task or determined by the target user negotiating with the engagement platform.
And 106, acquiring the performance behavior data of the target user.
The present embodiment does not limit the specific manner in which the agreement platform obtains the fulfillment behavior data of the target user, for example, the fulfillment behavior data of the target user may be directly sent to the agreement platform by the target user client.
In yet another illustrated embodiment, a commitment platform interfaces with a number of commitment task providers, the commitment platform including commitment tasks provided by the number of commitment task providers; the appointed task provider comprises a server for providing service for a user to execute the fulfillment behavior of the appointed task, and the fulfillment behavior data of the target user can be directly sent to the appointed platform by the client of the target user or can be forwarded to the appointed platform by the server of the appointed task provider; correspondingly, the acquiring, by the agreement platform, the performance behavior data of the target user includes: and the appointment platform acquires the fulfillment behavior data of the target user, which is sent by the appointment task provider.
Step 108, when the actual performance behavior data meets the performance conditions included in the performance contract, performing a reward to the target user based on the performance reward.
In order to implement a reward for actual performance of a target user to encourage a user's willingness to perform a contract, the contract platform may implement a reward for the target user based on the performance reward included in a performance contract when the actual performance data satisfies the contracted performance conditions. Specifically, based on the fact that agreement performance is directly embodied in the user credit degree, the agreement platform can create a corresponding credit score for the target user, and when actual performance behavior data of the target user meets the agreed performance conditions, the user credit score corresponding to the target user on the agreement platform is increased.
The credit score of the target user on the agreement platform can provide credit endorsements for the user in other service applications butted with the agreement platform, so that when the user maintains good credit scores on the agreement platform, the other service applications can regard the user as a trusted user, the user is provided with the authority of good credit users such as deposit free, refund payment, loan financing and the like, and the life experience of the user in an internet community is improved.
The following embodiments of the present specification take a public context as an example to further illustrate the fulfillment data method provided by the present specification.
The traditional public service mode has no strong restriction, insufficient user driving force, few public service participating users, high participating threshold and low enthusiasm for public users to participate in public service; in the public welfare process, the user feels all the user, the user gradually loses interest in the public welfare process, and no power is used for continuing doing the public welfare process.
In view of the above, one or more embodiments of the present disclosure provide a block chain-based public service data processing method, which is applied to a public service platform installed on a block chain, that is, a service device included in the public service platform can be used as a node device of the block chain to perform data processing on the basis of the block chain. The public service platform, as the engagement platform according to the embodiments, may display a plurality of public service tasks, for example, the public service platform may interface with a plurality of public service institutions to receive the public service tasks provided by the public service institutions, and a user of the public service platform may participate in engagement and execution of the public service tasks.
The block chain or block chain network described in this specification may specifically refer to a P2P network system having a distributed data storage structure, where the account book data in the block chain is distributed in temporally consecutive blocks (blocks), and the latter block may contain a data summary of the former block, and according to the specific consensus mechanism (such as POW, POS, DPOS, or PBFT), a full backup of data of all or part of nodes is achieved.
The real data generated by the physical world can be constructed into a standard transaction (transaction) format supported by a block chain, then is issued to the block chain, the node equipment in the block chain performs consensus processing on the received transaction, and after the consensus is achieved, the node equipment serving as an accounting node in the block chain packs the transaction into a block and performs persistent evidence storage in the block chain.
Regardless of which consensus algorithm is adopted by the block chain, the accounting node can pack the received transaction to generate a latest block and send the latest block to other node devices for consensus verification. If the latest block is received by other node equipment and no problem is proved, the latest block can be added to the tail of the original block chain, so that the accounting process of the block chain is completed. The transactions contained in the block may also be performed during the process of the other nodes verifying the new block sent by the accounting node.
It should be noted that, each time a block chain generates a latest block, after a transaction in the latest block is executed, the corresponding status of the executed transactions in the block chain may change accordingly, for example, in the block chain structured by an account model, the account status of an external account or an intelligent contract account may also generally send a corresponding change along with the execution of the transaction.
For example, when a "transfer transaction" is completed in a block, the balances of the transferring party account and the transferring party account associated with the "transfer transaction" (i.e., the field values of the Balance fields of these accounts) are usually changed.
For another example, the "intelligent contract invocation transaction" in the block is used to invoke an intelligent contract deployed on the blockchain, invoke the intelligent contract within the EVM corresponding to the node device to execute the "intelligent contract invocation transaction", and update the data state corresponding to the intelligent contract invocation transaction according to the execution result.
In practical applications, whether public, private, or alliance, it is possible to provide the functionality of a smart contract (Smartcontract). An intelligent contract on a blockchain is a contract on a blockchain that can be executed triggered by a transaction. An intelligent contract may be defined in the form of code.
Taking an Etherhouse as an example, a user is supported to create and call some complex logic in the Etherhouse network. The ethernet workshop is used as a programmable block chain, and the core of the ethernet workshop is an ethernet workshop virtual machine (EVM), and each ethernet workshop node can run the EVM. The EVM is a well-behaved virtual machine through which various complex logic can be implemented. The user issuing and invoking smart contracts in the etherhouse is running on the EVM. In fact, the EVM directly runs virtual machine code (virtual machine bytecode, hereinafter referred to as "bytecode"), so the intelligent contract deployed on the blockchain may be bytecode.
After Bob sends a Transaction (Transaction) containing information to create a smart contract to the ethernet network, each node may perform the Transaction in the EVM, as shown in fig. 2. The From field of the transaction in the figure is used for recording the address of the account initiating the creation of the intelligent contract, the contract code stored in the field value of the Data field of the transaction can be byte code, and the field value of the To field of the transaction is a null account. After the nodes reach the agreement through the consensus mechanism, the intelligent contract is successfully created, and the follow-up user can call the intelligent contract.
After the intelligent contract is established, a contract account corresponding to the intelligent contract appears on the block chain, and the block chain has a specific address; for example, "0 x68e12cf284 …" in each node in fig. 2 represents the address of the contract account created; the contract Code (Code) and account store (Storage) will be maintained in the account store for that contract account. The behavior of the intelligent contract is controlled by the contract code, while the account storage of the intelligent contract preserves the state of the contract. In other words, the intelligent contract causes a virtual account to be generated on the blockchain that contains the contract code and account storage.
As mentioned above, the Data field containing the transaction that created the intelligent contract may hold the byte code of the intelligent contract. A bytecode consists of a series of bytes, each of which can identify an operation. Based on the multiple considerations of development efficiency, readability and the like, a developer can select a high-level language to write intelligent contract codes instead of directly writing byte codes. For example, the high-level language may employ a language such as Solidity, Serpent, LLL, and the like. For intelligent contract code written in a high-level language, the intelligent contract code can be compiled by a compiler to generate byte codes which can be deployed on a blockchain.
Taking the Solidity language as an example, the contract code written by it is very similar to a Class (Class) in the object-oriented programming language, and various members including state variables, functions, function modifiers, events, etc. can be declared in one contract. A state variable is a value permanently stored in an account Storage (Storage) field of an intelligent contract to save the state of the contract.
As shown in FIG. 3, still taking the Etherhouse as an example, after Bob sends a transaction containing the information of the calling intelligent contract to the Etherhouse network, each node can execute the transaction in the EVM. The From field of the transaction in the figure is used for recording the address of the account initiating the intelligent contract calling, the To field is used for recording the address of the intelligent contract called, and the Data field of the transaction is used for recording the method and the parameters for calling the intelligent contract. After invoking the smart contract, the account status of the contract account may change. Subsequently, a certain client can check the account status of the contract account through the accessed block chain node.
The intelligent contract can be independently executed at each node in the blockchain network in a specified mode, and all execution records and data are stored on the blockchain, so that after the transaction is executed, transaction certificates which cannot be tampered and lost are stored on the blockchain.
The execution result of the smart contract may be in the form of a transaction execution Log (Log) stored in the MPT receipt tree; alternatively, the Key-Value pair can be stored in the Storage tree of the intelligent contract.
A schematic diagram of creating an intelligent contract and invoking the intelligent contract is shown in fig. 4. An intelligent contract is created in an Ethernet workshop and needs to be subjected to the processes of compiling the intelligent contract, changing the intelligent contract into byte codes, deploying the intelligent contract to a block chain and the like. The intelligent contract is called in the Ethernet workshop, a transaction pointing to the intelligent contract address is initiated, the EVM of each node can respectively execute the transaction, and the intelligent contract code is distributed and operated in the virtual machine of each node in the Ethernet workshop network.
In this embodiment, the public service platform and the public service organization may include node devices of a block chain in addition to their respective service systems; the node equipment of the public service platform can be used as a publisher of the performance contract, the intelligent contract creation transaction containing the performance contract code is sent to the block chain, and when the intelligent contract creation transaction is passed by the block chain consensus, the block chain can be deployed with the performance contract.
Fig. 5 illustrates a block chain-based commonwise data processing method provided in an exemplary embodiment of the present specification, in which the performance contract generated by the commonwise platform is deployed and executed on the block chain as an intelligent contract. As shown in fig. 5, the method includes:
The public welfare agency can provide public welfare tasks including: the poverty-relief service task, the big disease rescue task, the dynamic environment protection task, the education and learning-aid task and the like can participate in the public service task serving as the performance condition at one time, and can also comprise the action of finishing a preset public service target in a preset time period, for example, finishing preset participation times and participation distances in the preset time period, such as the number of trees planted in ant forest activities, the times or the distance of taking a bus subway during green travel and the like. Therefore, each public service task can correspond to at least one performance condition, and the performance condition can be contained in the public service task content and displayed on the public service platform; in order to facilitate the user to complete the performance conditions in accordance with the performance capabilities of the user, the user may also negotiate with the equity platform to create the performance conditions corresponding to the equity tasks selected by the user in the generated performance contract.
The present specification does not limit the specific process of the user negotiating with the public service platform to obtain the performance conditions corresponding to the public service tasks, which are included in the performance contract, and those skilled in the art can set up a corresponding negotiation process on the public service platform based on the types and contents of the public service tasks.
In an illustrated embodiment, the negotiation process may include:
the public service platform pushes the public service tasks and a plurality of performance condition options respectively corresponding to the public service tasks to a user client side, and outputs and displays the user client side; wherein, different performance condition options respectively correspond to different increasing amplitudes (or decreasing amplitudes) of the credit scores aiming at the user;
and acquiring a public service task selected by the user from the public service tasks and a performance condition option selected from a plurality of performance condition options corresponding to the public service task, so as to complete negotiation processing of the performance condition aiming at the target public service option with the target user.
Alternatively, the magnitude of the increase or decrease in the credit score may be determined by the target user negotiating with the public service platform.
Based on the manner described in one or more embodiments, based on the information interaction between the public service platform and the user client, the public service platform may create a performance contract that is achieved based on the target user executing the target public service mission, where the performance contract includes a performance condition corresponding to the target public service mission and a magnitude of improvement in credit score of the target user when the performance condition is satisfied.
Optionally, the participants of the performance contract may include, in addition to the target user and the restriction platform, a public welfare agency providing the target public welfare subject matter, so as to restrict the public welfare agency to provide accurate and effective public welfare tasks, or, the public welfare agency may actually convert the public welfare behavior contributed by the user into a specific public welfare event result, for example, actually apply the beneficence of the user donation to public welfare events such as public welfare events indicated by the target public welfare subject matter, poverty support, big illness rescue, animal protection, environmental protection, education and learning assistance.
The performance conditions agreed by the target user for executing the target public service task may include participation in the target public service tasks such as poverty-relief, big illness rescue, mobile security, environmental protection, or education and learning-aid projects, or finishing preset public service target behaviors in a preset time period, such as participation frequency threshold, public service participation time threshold, public service participation geographic distance threshold, and the like.
In yet another illustrative embodiment, to improve the execution efficiency and transparent disclosure of the execution process of the performance contract, the equity platform may generate intelligent contract code that may be deployed as a blockchain based on the performance contract.
Optionally, the credit score management logic further includes, when the performance behavior data of the target user does not satisfy the performance condition, decreasing the credit score of the target user based on a decrease range corresponding to the performance condition.
The performance behavior data of the target user may be sent to the block chain by the user client, or sent to the block chain by the user client through a node device of a public service platform, or the target user may execute an actual performance behavior in a service system of a public service organization providing the target public service task, so that the node device of the public service organization sends the actual performance behavior data generated by the user to the block chain, so that the node device of the block chain may receive the intelligent contract invocation transaction.
In yet another illustrated embodiment, the intelligent contract further declares a magnitude of decrease in credit score for the user when the equity mission performed by the user does not satisfy the fulfillment conditions;
in this embodiment, the process of executing the intelligent contract by the node device of the blockchain further includes: calling a judgment logic corresponding to a contract code in an intelligent contract corresponding to the target public service task, and judging whether the fulfillment behavior data meets fulfillment conditions corresponding to the target public service task; and if the performance behavior data does not meet the performance condition corresponding to the target public service task, further calling credit score management logic corresponding to contract codes in the intelligent contract, and reducing the credit score of the target user based on the reduction range.
In one or more of the embodiments shown above, the fulfillment behavior data of the user may be included in a distributed database of the blockchain, and the tamper-proof mechanism of the blockchain effectively guarantees the true reliability of the fulfillment behavior data; and taking the transaction containing the performance behavior data as an intelligent contract triggering condition, directly calling an intelligent contract execution judgment logic, judging whether the performance behavior data of the user meets the performance condition declared by the intelligent contract code, and calling a credit score management logic of the intelligent contract when the performance behavior data of the user meets the performance condition declared by the intelligent contract code, so as to increase the credit score of the user in the block chain network, thereby providing credit endorsements for the user when using various applications based on the block chain network. The intelligent contracts can be called and triggered at any time, execution efficiency of rewarding the user performance is improved, the intelligent contract codes are commonly identified in the blockchain network, and the execution process of the intelligent contracts is visible and commonly identified at each node of the blockchain network, so that fairness and transparency of credit scoring rewarding of the user performance are improved.
The existing network application provides some channels for improving the credit score of a user, for example, borrowing the user to financial institutions such as banks and the like, the user returns arrears according to appointments, the financial institutions user service end collects the borrowing and repayment behaviors of the user, and the credit score of the user is evaluated by using a credit score model based on the behaviors. One or more embodiments provided in the present specification add a way for a user to improve his/her credit score: by appointing tasks with other users or organizations, and actually executing the tasks according to the appointments. Specifically, the user can negotiate the performance conditions of the public service tasks with the public service platform, and deploy the performance condition judgment logic and the credit score rewarding logic as the execution logic of the intelligent contract into the block chain; through the calling execution of the intelligent contract, a technical basis is accurately and openly provided for the improvement of the credit score of the user.
Optionally, when the participant of the performance contract further includes a public service organization providing the target public service mission, the intelligent contract may further declare a judgment logic and a credit score management logic for the performance behavior of the public service organization, and increase the credit score of the public service organization when it is determined that the public service organization actually converts the public service performance behavior contributed by the user into an agreed public service processing result.
The above steps 502 to 506 only illustrate a method for separately deploying the intelligent contracts based on the contract performed by the user and the public service platform, and the description does not limit the deployment method of the intelligent contracts corresponding to the public service tasks.
In yet another illustrated embodiment, the node device of the public service platform may further deploy a creation template of a performance contract in the blockchain, where the creation template is also deployed in the blockchain in the form of an intelligent contract, and issues data of a performance contract agreed by a user with the public service platform (or part of key data of the performance contract) to the blockchain, and the data may invoke the creation template intelligent contract, cause the creation template intelligent contract to generate intelligent contract code content of the performance contract based on the data of the performance contract, and issue the intelligent contract code content of the performance contract to the blockchain, so as to further deploy the intelligent contract of the performance contract in the blockchain. By the adoption of the method for establishing and deploying the performance contract, the efficiency of establishing the performance contract is further improved.
In another illustrated embodiment, the public service platform may also deploy an intelligent contract for each public service task provided by each public service organization, after the public service platform and the user negotiate to generate a performance contract based on a specific public service task, the performance contract (or and the score management logic) negotiated by each user may be saved into the intelligent contract corresponding to the specific public service task by calling the intelligent contract corresponding to the specific public service task, and in a subsequent data processing process, the intelligent contract corresponding to the specific public service task is called based on the user identifier and the performance behavior data of the user, and the determination logic and the score management logic are executed.
Corresponding to the above flow implementation, the embodiment of the present specification further provides a public welfare data processing apparatus 60 based on a block chain.
