The technical solution of the embodiment of the present disclosure is explained in detail below:
first, the present exemplary embodiment provides a virtual resource acquisition method based on a block chain. The virtual resource obtaining method based on the block chain may be applied to the server 105, and may also be applied to one or more of the terminal devices 101, 102, and 103, which is not particularly limited in this exemplary embodiment. In this exemplary embodiment, taking the example that the server corresponding to the first block link point executes the method as an example, referring to fig. 3, the method for acquiring virtual resources based on a block chain may include the following steps S310 to S340:
step S310, obtaining the uploaded crowd funding configuration information, and creating a target intelligent contract corresponding to the crowd funding configuration information in the target block chain;
step S320, broadcasting the crowd funding configuration information to a second block chain node through the target block chain;
step S330, acquiring virtual resource delivery information uploaded by the link points of the second block based on the target intelligent contract, and judging whether virtual resources corresponding to the virtual resource delivery information are larger than or equal to a virtual resource threshold value;
step S340, if it is determined through the target intelligent contract that the virtual resource is greater than or equal to the virtual resource threshold, acquiring the virtual resource.
In the method for acquiring virtual resources based on the block chain provided by the exemplary embodiment, on one hand, the target block chain is used as a third-party mechanism of a notarization crowd funding project, so that the non-falsification of resource circulation in the crowd funding process is ensured, and the credibility of the crowd funding process is improved; on the other hand, the logic of the crowd funding project is automatically executed through an intelligent contract on the target block chain, when the virtual resource uploaded by the second block chain node (crowd funding party) is larger than or equal to the virtual resource threshold value, the virtual resource is sent to the first block chain node (initiator), and when the uploaded virtual resource is smaller than the virtual resource threshold value, the virtual resource is returned to the second block chain node, the return efficiency of the virtual resource is improved, and the use experience of a user is improved.
The above steps of the present exemplary embodiment will be described in more detail below.
In step S310, the uploaded crowd funding configuration information is obtained, and a target intelligent contract corresponding to the crowd funding configuration information is created in the target block chain.
In an example embodiment of the disclosure, the crowd funding configuration information may refer to information corresponding to a crowd funding project initiated by an initiator through a first block chain node, for example, the crowd funding configuration information may be information related to a creative item for crowd funding, or may be expected crowd funding funds or a crowd funding time interval corresponding to the crowd funding project, and of course, the crowd funding configuration information may also be enterprise information or personal information corresponding to the initiator, which is not particularly limited in this example embodiment. The target block chain may be a block chain corresponding to the crowd-funding service, for example, the target block chain may be a public chain associated with the crowd-funding service or an alliance chain associated with the crowd-funding service, which is not particularly limited in this example embodiment. A smart contract may refer to a modular, reusable, automatically executing script that runs on a blockchain. When the intelligent contract is deployed, the byte codes compiled by the compiler are stored in the block chain, and a storage address is correspondingly arranged. When the preset condition occurs, a transaction is sent to the contract address, all nodes in the whole network execute the operation code generated by compiling the intelligent contract, and finally, the execution result is written into the block chain. The target intelligent contract may refer to an intelligent contract deployed on a target blockchain for executing crowd-funding business, and may be written in languages of solicity, Serpent, LLL, and Mutan.
Before deploying a target intelligent contract corresponding to crowd funding configuration information in a target block chain, the crowd funding configuration information needs to be checked. Specifically, fig. 4 schematically illustrates a flow diagram of auditing crowd funding configuration information according to an embodiment of the present disclosure.
Referring to fig. 4, in step S410, the uploaded crowd funding configuration information is obtained, and the crowd funding configuration information is subjected to an auditing process.
In an example embodiment of the present disclosure, the audit processing may refer to a processing procedure of verifying and auditing the crowd funding configuration information uploaded by the applicant, for example, the audit processing may be a verification procedure of verifying whether the personal information or the enterprise information corresponding to the applicant in the crowd funding configuration information is correct or complete, or may be an audit procedure of auditing creativity or value of an creative item for crowd funding, and of course, the audit processing procedure may also be other processing procedures capable of screening the crowd funding configuration information, which is not particularly limited in this example embodiment.
Step S420, if it is determined that the crowd funding configuration information is approved, creating a target intelligent contract corresponding to the crowd funding configuration information in the target block chain.
In an example embodiment of the present disclosure, if it is determined that the crowd funded configuration information is approved, a target intelligent contract corresponding to the crowd funded configuration information is deployed in the target block chain, of course, the target intelligent contract may also be a preset intelligent contract, for example, a template provided for the crowd funded configuration information of an applicant, and if the applicant fills the crowd funded configuration information through the template, the preset intelligent contract is directly deployed in the target block chain, which is only schematically illustrated here, and this part should cause any special limitation to this example embodiment.
And step S430, if the crowd funding configuration information is determined not to pass the audit, returning the crowd funding configuration information to obtain updated crowd funding configuration information.
In an example embodiment of the disclosure, if it is determined that the crowd funding configuration information is not approved, the crowd funding configuration information which is not approved is returned to the terminal device corresponding to the applicant, the applicant is guided to refill the crowd funding configuration information, and when the applicant uploads the modified crowd funding configuration information, the updated crowd funding configuration information is obtained.
In the embodiment of the example, the uploaded crowd funding configuration information is audited, crowd funding configuration information which does not meet the regulation can be filtered, the quality of the crowd funding configuration information is improved, the waste of resources is reduced, and the selection experience of the crowd funding party is improved.
In step S320, the crowd-funding configuration information is broadcast to a second blockchain node through the target blockchain.
In an example embodiment of the present disclosure, the second block link point may refer to a terminal or a server connected to the target block chain, and the crowd funder (virtual resource provider) may view the crowd funded configuration information through the second block chain node and upload or transmit the virtual resource. After the crowd funding configuration information is approved, the crowd funding configuration information is broadcasted to the second block chain node through the target block chain, so that the crowd funding party receives and checks the crowd funding configuration information through the second block chain node.
Specifically, a state and an execution result corresponding to the target intelligent contract are inquired in the target block chain according to the crowd funding project code. The crowd-funding project code may be a unique identification code generated after the crowd-funding configuration information is uploaded to the target block chain, and the applying party or the crowd-funding party may obtain the crowd-funding configuration information or a circulation process of the crowd-funding configuration information corresponding to the virtual resource information according to the crowd-funding project code. By generating the crowd-funding project code corresponding to the crowd-funding configuration information, an applicant or a crowd-funding party can inquire the crowd-funding progress of the crowd-funding project corresponding to the crowd-funding configuration information through the target block chain more conveniently, and the use experience of a user is improved.
In step S330, based on the target intelligent contract, obtaining virtual resource delivery information uploaded by the link point of the second block, and determining whether a virtual resource corresponding to the virtual resource delivery information is greater than or equal to a virtual resource threshold.
In an example embodiment of the disclosure, the virtual resource delivery information may refer to operation information related to virtual resources performed on a crowd-funding item corresponding to the crowd-funding configuration information by the crowd-funding party, for example, the virtual resource delivery information may be a quantity of virtual resources uploaded to a target block chain by the crowd-funding party, or a quantity of virtual resources to be uploaded to the target block chain by the crowd-funding party (that is, a quantity of virtual resources reserved for payment), and of course, the virtual resource delivery information may also be operation information related to virtual resources performed on a crowd-funding item corresponding to the crowd-funding configuration information by other crowd-funding parties, which is not limited in this example embodiment. The virtual resource may refer to a virtual resource that can be traded in the target block chain and has a certain value, for example, the virtual resource may be a Bitcoin (Bitcoin, which may refer to an encrypted digital currency) traded in the target block chain, and of course, the virtual resource may also be another resource that can be traded in the target block chain, which is not limited in this example embodiment. The virtual resource threshold may be a fixed number corresponding to a virtual resource preset in the target intelligent contract, and the virtual resource threshold may be set by crowd funding configuration information, for example, the virtual resource threshold may be two bit coins, that is, when the virtual resource is greater than or equal to the two bit coins, it is considered that the crowd funding project corresponding to the crowd funding configuration information has completed crowd funding; when the virtual resource is smaller than two bit coins, it is considered that the crowd funding project corresponding to the crowd funding configuration information does not complete crowd funding, and of course, this is only an exemplary illustration here, and this is not specifically limited in this example embodiment.
Specifically, based on the target virtual machine, a target intelligent contract corresponding to the crowd-funding configuration information is created in the target block chain. The target virtual machine may refer to a virtual machine that executes a target intelligent contract in a target block chain, for example, the target virtual machine may be an Ethernet Virtual Machine (EVM), or may be another type of virtual machine that can execute the target intelligent contract in the target block chain, which is not limited in this example embodiment.
Further, updating the state corresponding to the target intelligent contract through the target virtual machine; and saving the state and the execution result corresponding to the target intelligent contract to the target block chain. And when receiving the instruction of crowd funding business transaction, the target virtual machine executes the instruction set corresponding to the target intelligent contract and updates the state corresponding to the target intelligent contract after each execution. And after the execution is successful, the target virtual machine carries out shutdown operation, the execution of the target intelligent contract is finished after the shutdown, and the execution state and the execution result corresponding to the target intelligent contract are stored in the target block chain, so that the second block chain link point can acquire and check the execution state and the execution result corresponding to the target intelligent contract.
Specifically, before determining whether the virtual resource corresponding to the virtual resource delivery information is greater than or equal to the virtual resource threshold, it is further necessary to further determine virtual resource delivery time information in the crowd funding configuration information. The virtual resource delivery time information may refer to time for performing virtual resource delivery on the crowd funding project corresponding to the crowd funding configuration information, and when the time exceeds the time, the crowd funding process is ended. Fig. 5 schematically shows a flowchart of determining virtual resource delivery information according to an embodiment of the present disclosure.
Referring to fig. 5, in step S510, it is determined whether the virtual resource delivery time information is greater than or equal to a time threshold.
In an example embodiment of the disclosure, the time threshold may be a time period preset in the target intelligent contract and capable of performing virtual resource delivery on the crowd-funding item corresponding to the crowd-funding configuration information, and the time threshold may be set by the crowd-funding configuration information, for example, the time threshold may be 30 days, that is, when the time displayed by the crowd-funding configuration information in the target block chain is greater than or equal to 30 days, it is considered that the crowd-funding item corresponding to the crowd-funding configuration information is overtime, and it is necessary to end the crowd-funding process; when the virtual resource is less than 30 days, it is considered that the crowd funding project corresponding to the crowd funding configuration information does not complete crowd funding, and the crowd funding process needs to be continued.
Step S520, if it is determined that the virtual resource delivery time information is greater than or equal to the time threshold, rejecting to receive the virtual resource delivery information uploaded by the link point of the second block.
In an example embodiment of the disclosure, if it is determined that the virtual resource delivery time information is greater than or equal to the time threshold, the crowd-funding item corresponding to the crowd-funding configuration information is considered to be overtime, and the crowd-funding process cannot be continued, at this time, the virtual resource delivery information uploaded by the link point of the second block is rejected from being received, and the corresponding crowd-funding party is notified that the crowd-funding process is finished.
Step S530, if it is determined that the virtual resource delivery time information is smaller than the time threshold, continue to acquire the virtual resource delivery information uploaded by the link point of the second block.
In an example embodiment of the disclosure, if it is determined that the virtual resource delivery time information is less than the time threshold, it is considered that the crowd funding item corresponding to the crowd funding configuration information is not completed, and the crowd funding process needs to be continued, at this time, the virtual resource delivery information uploaded by the link points of the second block is continuously acquired until the virtual resource delivery time information is greater than or equal to the time threshold, or the virtual resource is greater than or equal to the virtual resource threshold, it is considered that the crowd funding item corresponding to the crowd funding configuration information is completed, and the crowd funding process is ended.
By setting the virtual resource delivery time information and the time threshold, overtime crowd funded projects or worthless crowd funded projects can be removed in time, resources are saved, and the working efficiency of the system is improved.
In step S340, if it is determined by the target smart contract that the virtual resource is greater than or equal to the virtual resource threshold, the virtual resource is acquired.
In an example embodiment of the disclosure, if it is determined through the target intelligent contract that the virtual resource is greater than or equal to the virtual resource threshold, the crowd-funding project corresponding to the crowd-funding configuration information is considered to have completed the crowd-funding process, at this time, the target intelligent contract sends the virtual resource uploaded by the second block link point to the first block link node, and the first block link node acquires the virtual resource sent by the target intelligent contract and sends the virtual resource to the applicant.
Specifically, fig. 6 schematically shows a flowchart of a virtual resource acquisition method based on a block chain according to another embodiment of the present disclosure.
Referring to fig. 6, in step S650, if it is determined by the target intelligent contract that the virtual resource is less than the virtual resource threshold, the virtual resource is returned to the second blockchain node by the target intelligent contract.
In another example embodiment of the disclosure, if it is determined through the target intelligent contract that the virtual resource is smaller than the virtual resource threshold value, and the virtual resource delivery time information is greater than or equal to the time threshold value at this time, it is considered that the crowd-funded project corresponding to the crowd-funded configuration information is overtime and the crowd-funded process is not completed, the crowd-funding of this time is redeemed, and the uploaded virtual resource is returned to the second block chain node corresponding to each crowd-funding party.
Fig. 7 schematically shows a flowchart of virtual resource acquisition according to an embodiment of the present disclosure.
Referring to fig. 7, in step S701, crowd funding configuration information uploaded by an applicant is received; step S702, firstly, the uploaded crowd funding configuration information is audited to determine whether the crowd funding configuration information meets the conditions of the crowd funding process, when the audit of the crowd funding configuration information passes, the step S703 is executed, otherwise, the step S704 is executed; step S703, broadcasting crowd-funding configuration information to a second block chain node through the target block chain; step S704, returning the crowd funding configuration information which is not approved to the applicant, guiding the applicant to modify the crowd funding configuration information, receiving the updated crowd funding configuration information and continuing to execute the step S702; step 705, executing a target intelligent contract deployed in the target block chain through the target virtual machine, so as to obtain virtual resource delivery information uploaded by the second block chain link point through the target intelligent contract; step S706, judging whether the virtual resource delivery time information is larger than or equal to the time threshold, if the virtual resource delivery time information is judged to be larger than or equal to the time threshold, executing step S707, otherwise executing step S705; step S707, determining whether the virtual resource is greater than or equal to the virtual resource threshold, if the virtual resource is greater than or equal to the virtual resource threshold, executing step S708, otherwise executing step S709; step S708, acquiring virtual resources sent by the target intelligent contract, and sending the virtual resources to the applicant; step S709, returning the virtual resource to the corresponding second block chain node; step S710, when performing steps S705 to S709, updates the execution state of the target intelligent contract through the target virtual machine, and broadcasts the execution state of the target intelligent contract and the execution result to the target block chain.
