Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is an implementation environment of a value transferring method provided by an embodiment of the present invention, and referring to fig. 1, the implementation environment may include a plurality of computer devices, where each computer device may be a server or a terminal.
The plurality of computer devices may be a plurality of node devices in a blockchain system, and one or more node devices in the blockchain system may execute the value transfer method provided by the embodiment of the present invention. For example, the blockchain system may include servers of various organizations within the federation, and one or more of the servers may perform the value transfer methods provided by embodiments of the present invention. The plurality of computer devices may be a plurality of node devices of the same organization, or may be node devices of different organizations, which is not limited in the embodiment of the present invention.
In the embodiment of the invention, the blockchain system can carry out value transfer according to the first transaction data of the transaction equipment. The transaction device may be a computer device in the blockchain system, or may be a computer device outside the blockchain system, which is not limited in the embodiment of the present invention.
Fig. 2 is a flowchart of a value transfer method according to an embodiment of the present invention, where the method is applied to any node device on a blockchain system, and referring to fig. 2, the method may include:
201. The node device extracts first transaction data and digital asset information of the transaction device from a blockchain of the blockchain system.
The digital asset information comprises the total number of digital assets of the transaction device and the number of digital assets of each user account corresponding to the transaction device.
In an embodiment of the invention, the transaction device may be used to provide transaction services. The user may conduct a transaction operation on the transaction device, the transaction device automatically providing transaction services thereto and transmitting first transaction data to the blockchain system, which performs a value transfer based on the first transaction data.
For example, the transaction device may be a vending machine, the user may purchase the commodity on the vending machine, specifically, the user may select the commodity, the vending machine displays a payment two-dimensional code to the user, the user may complete payment by scanning the two-dimensional code, the payment platform may send a payment completion message to the vending machine, or the user may complete payment by cash, so that the vending machine provides the commodity to the user, and may send the first transaction data of this time to the node device, and the node device links the first transaction data.
The first transaction data of the transaction device may be stored in the blockchain through the following processes from the first step to the third step:
step one, node equipment receives first transaction data sent by transaction equipment.
The first transaction data may include transaction benefits and transaction costs, and of course, the first transaction data may also include identification information of transaction items, transaction quantity, transaction time, transaction user account numbers, and the like, which are not limited in the embodiment of the present invention.
In one possible implementation, the first transaction data may further include identification information of a transaction device, where the identification information of the transaction device may determine that the first transaction data is data generated on the transaction device. In another possible implementation manner, the first transaction data may not include identification information of the transaction device, but the node device may establish a correspondence between the first transaction data and the identification information of the transaction device after receiving the first transaction data. The embodiment of the invention is not limited to the specific implementation manner.
And step two, the node equipment generates a second block based on the first transaction data.
The node device may receive the first transaction data, may uplink the first transaction data, and may check the authenticity and accuracy of the data on the blockchain during uplink, for example, may check the authenticity of the first transaction data according to a transaction rule. In the embodiment of the present invention, the block in which the second transaction data is stored is referred to as a first block, and the block in which the first transaction data is stored is referred to as a second block.
Specifically, the node device may generate a second block based on the first transaction data, the second block including the first transaction data therein. The node device may broadcast the second block to other node devices in the blockchain system such that the plurality of node devices in the blockchain system agree on the second block.
The process of generating the second block by the node device may be: the last block in the current blockchain is called the last block, i.e., the last block is the block with the highest block height in the current blockchain, and the block being generated by the node device is called the next block (i.e., the second block). The node device may obtain all information of the previous block from the blockchain, so that a block header feature value of the previous block may be generated based on all information of the previous block, and feature value calculation is performed on information of a contract to be stored in the next block and the first transaction data to obtain a block body feature value of the next block, and further, the node device may store the block header feature value of the previous block, the block body feature value of the next block (may further include a version number, a difficulty value, a timestamp, etc.) to a block header of the next block, and store information of the contract, the first transaction data, etc. to a block body of the next block, so as to generate the next block. Thus, the previous block and the next block are related by the block head characteristic value of the previous block, and the purpose of connecting blocks in series in the block chain can be realized. In the embodiment of the present invention, the next block is a second block, and the generation process of the second block can refer to the generation process of the next block, and the second block and the previous block are connected in series in the blockchain. Of course, the foregoing is merely an example of generating a block, and other implementation manners may be adopted in the generating process of the second block, and the embodiment of the present invention does not limit the specific generating process of the second block.
For the above-mentioned consensus process for the second block, the blockchain system may verify the above-mentioned feature value generated in the second block, or may verify the accuracy of the first transaction data that is stored this time.
And step three, when the second block passes through the consensus of the block chain system, the node equipment adds the second block to the block chain of the block chain system.
When the second block passes through the consensus of the blockchain system, the information in the second block is verified, and the second block is true and accurate, so that the node device can add the second block to the blockchain.
Through the above process, the node device may store the first transaction data of the transaction device on the blockchain. For digital asset information, the transaction device may include a plurality of digital assets, and the user account may continue to obtain a portion of the transaction revenue for the transaction device by purchasing the digital asset of the transaction device. For example, the total number of digital assets of the transaction device may be 100, 20 digital assets are purchased by the user account a, 80 digital assets are purchased by the user account B, and the digital asset information is the information.
After the trading device generates trading revenue through the trade, the user account purchasing the digital asset of the trading device may obtain corresponding revenue from the trading revenue of the trading device. For example, in one particular application scenario, a user may invest in a vending machine, and the digital asset information is investment equity information, so that when the vending machine obtains profits by vending goods, the user who invests in the vending machine may obtain a score.
In one possible implementation manner, the step of transferring the value by the node device based on the first transaction data may be triggered periodically, for example, the period may be set to a target duration, and step 201 may be: every other target duration, the node device extracts first transaction data and digital asset information of the transaction device in the target duration from a blockchain of the blockchain system. The target duration may be set by a related technician according to requirements, which is not limited in the embodiment of the present invention.
For example, the target duration may be one day, so that in the above investment application scenario, the investor can acquire corresponding score every day, so that the aggressiveness of investment can be improved, and the promotion and use of vending machine operators and investors on vending machines are facilitated.
202. And the node equipment acquires the total value to be transferred according to the transaction income and the transaction cost in the first transaction data.
After the node device extracts the first transaction data, the total number value of the user account numbers corresponding to the transaction device to be transferred can be determined according to the transaction benefits and the transaction cost in the first transaction data. For example, in the above scenario of vending machine, the transaction benefit may be an amount of money that the vending machine obtains by vending the goods, and the transaction cost may include a cost of vending the goods, a gate rent, a maintenance fee, a damage fee, and the like.
In one possible implementation, the aggregate value may be a cost-effective benefit generated by the transaction device through the transaction. For example, the total value may be a net profit. In step 202, the node device may obtain a difference between the transaction benefit and the transaction cost, and use the difference as the total value to be transferred.
The total value may also be other than the pure profit, for example, a fee may be paid by the blockchain system for the value transfer, and the total value may be a first difference between the transaction benefit and the transaction cost and a second difference between the target cost, and the target cost may be the fee. The method for obtaining the total value may include various methods, and may be specifically set by a relevant person according to the use requirement, which is not limited in the embodiment of the present invention.
In a specific possible embodiment, the total value may be obtained by storing the total value in an intelligent contract, and the node device may invoke the intelligent contract to obtain the total value to be transferred based on the intelligent contract, the transaction benefit in the first transaction data, and the transaction cost.
203. And the node equipment determines second transaction data of each user account according to the total number of the digital assets, the digital asset number of each user account and the total number value to be transferred.
Wherein the second transaction data includes a value to be transferred to each user account.
After the node device obtains the total number value to be transferred, the value to be transferred to each user account, that is, the second transaction data, may be continuously determined. Specifically, the process of determining the second transaction data of each user account by the node device may be implemented in any one of the following manners one and two:
in a first mode, the node device determines a value corresponding to each digital asset according to the total number of the digital assets and the total number to be transferred, and determines second transaction data of each user account according to the digital asset number of each user account and the value corresponding to each digital asset, where the value included in the second transaction data is positively correlated with the digital asset number.
And according to the digital asset ratio of each user account and the total value to be transferred, determining second transaction data of each user account, wherein the numerical value included in the second transaction data is positively correlated with the digital asset number.
It will be appreciated that the greater the number of digital assets of a user account, the greater the number of values to be transferred to that user account. In the first mode, the value corresponding to each digital asset may be determined first, and then the value to be transferred to each user account may be determined according to the number of digital assets of each user account. In the second mode, the digital asset ratio of each user account may be determined first, and then the value to be transferred to each user account may be determined according to the digital asset ratio. The second transaction data includes a value that is positively correlated with the digital asset ratio. The greater the digital asset ratio, the greater the value included in the second transaction data. The foregoing provides two ways of determining the second transaction data, and the embodiment of the present invention is not limited to what way is specifically adopted.
In one possible implementation, the step 203 may also be implemented based on an intelligent contract, that is, the node device may invoke an intelligent contract to determine the second transaction data for each user account based on the intelligent contract, the total number of digital assets, the number of digital assets per user account, and the total value to be transferred.
The steps 202 and 203 are processes of determining the second transaction data of each user account according to the total number of digital assets, the number of digital assets of each user account, the transaction income and the transaction cost in the first transaction data, and in the process, the node device obtains the total value to be transferred according to the transaction income and the transaction cost in the first transaction data, and then distributes each user account. The node device may further allocate the digital asset total number, the digital asset number of each user account, the transaction benefit and the transaction cost in the first transaction data to each user account directly.
204. The node device generates a first block based on the second transaction data for each user account.
After the node device determines the second transaction data of each user account, the second transaction data may also be uplinked, and the uplink process is the same as the uplink process of the first transaction data shown in step 201, and may specifically be implemented by adopting step 204 and step 205. The node device may generate a first block based on the second transaction data of each user account, broadcast the first block to other node devices in the blockchain system, and then the plurality of node devices in the blockchain system consensus the first block.
The process of generating the first block by the node device is the same as the process of generating the second block in the step 201, and the process of consensus of the blockchain system for the first block is also the same as the process of consensus of the second block in the step 201, which is not repeated here in the embodiments of the present invention.
205. When the first block passes the consensus of the blockchain system, node devices add the first block to the blockchain.
When the first block passes through the consensus of the blockchain system, the information in the first block is verified, and the first block is true and accurate, so that the node device can add the first block to the blockchain.
For example, still taking the application scenario of the vending machine as an example, the node device calculates the score for each investor according to daily profit conditions of the vending machine, so that the score information is counted into the blockchain after the score. Thus investors can see the score of each day, the satisfaction of return on investment is greatly improved, the enthusiasm of investment can be effectively improved, the score information is transparent to individuals, and the credibility is improved.
In one possible implementation, due to a software vulnerability that may exist in the intelligent contract, if the content of the first block is not well checked, a target node device may be set, and the target node device checks the content of the first block to determine that the accounting information is accurate and reliable. The target node device may then be considered an observation node in the blockchain system, specifically, when the first block passes the consensus of the blockchain system, the node device sends the first block to the target node device, the target node device verifies the first block, and when a verification pass message of the target node device is received, the node device may add the first block to the blockchain.
In a possible implementation, after step 201, the node device may further set a start flag, where the start flag is used to indicate that the numerical transfer is started, and based on this, the node device may further be set to: when the first transaction data and the digital asset information of the transaction device are extracted from the blockchain of the blockchain system and the start identification is detected, the node device discards the extracted first transaction data and digital asset information of the transaction device. Therefore, through the starting mark, the situation that the transferred numerical value is wrong due to repeated triggering of the numerical value transfer according to the same first transaction data can be effectively avoided. In such an implementation, following step 205 described above, the node device may also set an end flag indicating that the value transfer is complete.
In one possible implementation, in step 205, the node device may perform a value transfer in addition to adding the first block to the blockchain system. Specifically, when the first block passes through the consensus of the blockchain system, the node device may send a value transfer request to the value transfer device, where the value transfer request may carry second transaction data of each second user account, and the value transfer device may perform value transfer based on the second transaction data of each user account, and return a value transfer result in a response manner. The node device may receive a transfer success response sent by the value transfer device. The transfer success response may be sent after the value transfer device successfully transfers the value based on the second transaction data. The value transfer device may be, for example, a paymate or banking device. After the determination of the value required for the value transfer, i.e. the transfer, can then take place.
After the step 201 to step 205, the node device distributes the benefits of the transaction device to the multiple user accounts, and links the distribution results, each user account may also check its own second transaction data by sending a transaction inquiry request to the node device. Specifically, the node device may receive a transaction query request of any user account, obtain second transaction data of the any user account from the blockchain according to identification information of the any user account, and send the second transaction data of the any user account to the any user account.
A specific example is provided below to exemplarily illustrate the above-described numerical value transfer process. Taking the application scenario of the vending machine as an example, the above process may be divided into two flows: a collection flow and a red separation flow.
The payment receiving process may be as shown in fig. 3, where a user may select a commodity on the vending machine, the vending machine may display a two-dimensional code for payment, the user may scan the two-dimensional code for payment through a payment application, the user's device may send payment information to a payment platform, after the payment platform completes payment, the payment platform may feed back a payment success message to the user, or may asynchronously notify the vending machine that the payment is successful, and the vending machine may send the commodity to the user, and link transaction data, that is, the process shown in step 201 above in which the first transaction data is added to the blockchain. The first transaction data may include, among other things, a product Identification number (ID), a quantity, a time, and a transaction device ID. The smart contract may be triggered to process the first transaction data on the blockchain, and specifically, the total revenue removal cost may be added, and the profit may be charged to the general ledger, where the cost may include various costs, such as commodity cost, door rent, maintenance cost, damage cost, etc., that is, the process shown in step 202 above.
For the process of sharing red, as shown in fig. 4, the transaction device may include a plurality of digital assets (referred to herein as token), and may automatically trigger an intelligent contract every day, or actively trigger to share red by an investor, where the investor is a token holder, may set a sharing start identifier first, and calculate the added profit and total number of token in the above-mentioned collection process through the intelligent contract to obtain a sharing red amount of each token, in this process, the statistical data on the blockchain may be transferred to the sharing red data, and the sharing red log is recorded, that is, the first transaction data on the blockchain is extracted in step 201, and then the first transaction data is processed. Then, by cycling all investor accounts, for each investor account, the current credit can be obtained by multiplying the credit of each token according to the number of tokens of the current investor, and the current credit is recorded on the blockchain. After the red separation is finished, the red separation profit can be reset, that is, the statistical data is converted into the red separation data through the steps, and after the red separation is finished, the red separation data is cleared, so that the red separation processing can be carried out on the first transaction data in batches without repeated processing. After the end of the red-out, a red-out end flag may be set.
The numerical value transfer method can solve the problems of large investment and untimely income of the vending machine in the early stage, fast financing in a manner of digital assets on the blockchain, fast occupying the market, enabling investors to obtain the red income regularly, combining the blockchain technology, transferring vending machine information, transaction data and investment equity information to the blockchain, solving the trust problem with lower cost, greatly reducing the marketing cost of the vending machine, and being more beneficial to popularization and use of the vending machine.
