Detailed Description

For the convenience of understanding the scheme of the embodiment of the present application, a brief description of related concepts is given below:

First, blockchain techniques.

Blockchain technology, also known as distributed ledger technology, is an emerging technology in which several computing devices participate in "accounting" (i.e., recording transaction data) together, maintaining a complete distributed database. Blockchain technology has been widely used in many fields because of its decentralized (i.e., no central node), public transparency, the ability of each computing device to participate in database records, and the ability to quickly synchronize data between computing devices.

Currently, blockchains can be divided into: public chains and alliance chains. A public chain refers to a blockchain that is readable by any device worldwide, or that any device can participate in the consensus verification process of a transaction. The federation chain, also called a community blockchain (consortium block chains), means that the federation is composed of participating members of a given blockchain, and business transaction information between the members is recorded in the blockchain, defining the size and rights of use. The deployment of blockchains of embodiments of the present disclosure may employ federated chains.

Second, blockchain nodes.

The blockchain in embodiments of the present disclosure may also be referred to as a blockchain system. The blockchain system in embodiments of the present disclosure includes a plurality of blockchain nodes (hereinafter may be simply referred to as nodes). The node is a device with communication function and storage function, such as a device with block chain data. Each node may either receive information or generate information. Communication and data synchronization is maintained between different nodes by maintaining a common blockchain. Specifically, in the blockchain system, any node can generate new blockchain data according to data related to transactions sent by a client, and issue the new blockchain data to other nodes in a broadcast mode, and the other nodes can verify the blockchain data. When all nodes in the blockchain system reach consensus, new blockchain data may be added to the blockchain.

Alternatively, a node in an embodiment of the present disclosure may be understood as a processing unit. In one implementation, a node may be a physical device, such as a server or computer. In another implementation, the node may be a virtual computer; virtual computers are a collective term for the operating environment that software in all types of virtualized devices virtualizes, and the concept includes virtual machines and containers. In other implementations, a node in an embodiment of the present disclosure may be a process or a thread; the thread is the minimum unit of the operation system capable of carrying out operation scheduling, is contained in the process and is the actual operation unit in the process; a process is a program in a computer that is a basic unit of resource allocation and scheduling by a system with respect to one run activity on a certain data set.

It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.

The blockchain-based transaction management method of the disclosed embodiments will be described in detail below with reference to the scenario described in fig. 1, with reference to fig. 2.

Fig. 2 schematically illustrates a flow chart of a blockchain-based transaction management method in accordance with an embodiment of the present disclosure. As shown in fig. 2, the transaction management method of this embodiment includes steps S210 to S250.

In step S210, the blockchain obtains a plurality of transactions, each transaction including a first commercial bank for performing a first transaction operation.

In the disclosed embodiments, "transaction" may refer to a transaction activity in the business arts, such as payment, collection, and the like. Multiple enterprises and multiple commercial banks may participate in the blockchain as nodes of the blockchain. After one of the enterprises puts forward a demand for funds transfer, multiple transactions may be generated by the enterprise platform, for example, company a is a head office, company b is a subcontracting company, company c is a material provider, the demand for funds transfer may include the demand put forward by company a for purchasing material, at which time the enterprise platform may generate two transactions, namely, one transaction in which company a pays company b (requires company b to purchase material), and one transaction in which company b pays company c (purchases material). The enterprise platform may upload multiple transactions to the blockchain by invoking a pre-configured smart contract. In addition to uploading multiple transactions to the blockchain, the enterprise platform may also update and query the contents of the ledger by invoking the intelligent contract.

The first transaction operation may be a payment operation, or may be a repayment operation, a transfer operation, or other transaction operation as would occur to one of skill in the art. Optionally, in an embodiment of the present disclosure, the first transaction operation is specifically a payment operation. The first commercial bank is a bank for making a payment, for example, company a makes a payment to company b through bank a, which is the first commercial bank of the embodiment of the present disclosure.

In step S220, the blockchain stores the plurality of transactions in the ledger of the blockchain and extracts the first commercial bank of each transaction.

In step S230, for each of the extracted first commercial banks, the blockchain counts transactions that execute the first transaction operation by the first commercial bank from a plurality of transactions, and extracts the transactions in a state to be executed therefrom, so as to obtain a first transaction set corresponding to the first commercial bank.

In embodiments of the present disclosure, the plurality of transactions may be each performed by a different first commercial bank, e.g., the plurality of transactions includes transaction X, transaction Y, and transaction Z, which perform the payment operation by bank a, and transaction Y performs the payment operation by bank B. The first transaction set counted for bank a then includes transaction X and transaction Z, and the first transaction set counted for bank B then includes transaction Y. After counting the first transaction set corresponding to each bank, in step S240, batch processing may be performed on multiple transactions of the bank, which will be described in detail below, and will not be described in detail here. Each of the plurality of transactions may include various states such as waiting, waiting to be executed, and execution completion, and may be specifically determined according to actual needs, which is not limited herein. Optionally, in the embodiment of the present disclosure, the states of at least two transactions in the multiple transactions may be associated with each other, for example, the multiple transactions include two transactions, the former transaction defaults to be executed before execution is completed, the state of the former transaction may be obtained when the state of the latter transaction is determined, and the latter transaction is determined to be in a waiting state when the former transaction has not been executed; when the execution of the previous transaction is completed, the latter transaction is determined to be in a state to be executed.

Alternatively, in the embodiment of the present disclosure, for each first commercial bank, in addition to extracting the first transaction set, the total number of transactions, the total amount of transactions, and the like may be counted, specifically may be determined according to actual needs, and is not limited herein.

In step S240, for each first transaction set, the blockchain sends a first transaction instruction to a first commercial bank corresponding to the first transaction set. The first transaction instruction is configured to enable the first commercial bank to execute a first transaction operation according to the transaction in the first transaction set and the first transaction instruction, and feed back an operation result of the first transaction operation.

In the embodiment of the disclosure, the first transaction instruction can include address information of the first commercial bank corresponding to the first transaction instruction, so that the blockchain can send the first transaction instruction to the first commercial bank corresponding to the first transaction instruction according to the address information. In an embodiment of the disclosure, the first transaction instruction may correspond to each transaction in the first transaction set one by one, and the first commercial bank may obtain, in response to the first transaction instruction, transaction content of one transaction corresponding to the first transaction instruction from the first transaction set, where the transaction content may include a payment account, a collection account, a transaction amount, and the like. The first commercial bank may perform a first transaction operation, such as a payment operation, based on the transaction content. The first commercial bank returns operation results to the blockchain after performing the first transaction operation, for example, the operation results may include a successful payment or a failed payment.

In step S250, the blockchain updates the state of the transaction corresponding to the operation result stored in the ledger according to the operation result.

In the disclosed embodiment, the status of each transaction in the ledger and the change in status are recorded, including, for example, in payment, in collection, etc., such that the ledger stores a complete flow of information of funds during the transfer. And the state of each transaction in the account book is updated according to the operation result of the first commercial bank, and meanwhile, the data in the account book can not be tampered by the characteristics of the blockchain, so that the information flow recorded in the account book is consistent with the actual condition of funds in the circulation process, and the security of the funds circulation is improved. Moreover, according to the embodiment of the disclosure, the state change of each transaction is recorded through the blockchain, and each enterprise participating in the fund circulation can check the state of each transaction, so that each transaction in the fund circulation process is disclosed and transparent, data sharing is realized, and fund supervision is facilitated.

The blockchain-based transaction management methods provided by embodiments of the present disclosure are further described below in conjunction with fig. 1-7.

Fig. 3 schematically illustrates a schematic diagram of an interaction process of a blockchain-based transaction management method according to an embodiment of the disclosure. As shown in fig. 3, the interactors of the embodiments of the disclosure include an enterprise platform, a blockchain, and business banks, wherein the enterprise platform and the blockchain are used to perform the blockchain-based transaction management method of the embodiments of the disclosure, and the enterprise platform and the blockchain may each be deployed in a server 105.

In the disclosed embodiments, various enterprises may participate in blockchains through enterprise platforms. The enterprise platform can generate a plurality of corresponding transactions according to the fund circulation demands put forward by the enterprise, and send the transactions up to the blockchain by calling the intelligent contract. The enterprise platform may also perform approval management and management of related information on the transactions prior to sending the multiple transactions to the blockchain. In addition, the enterprise platform can manage each enterprise, such as registration, login, logout, and the like.

Fig. 4 schematically illustrates a flow chart of generating multiple transactions according to an embodiment of the present disclosure.

As shown in fig. 4, in some embodiments, the transaction management method further includes a step of generating a plurality of transactions, and the step of generating the plurality of transactions includes steps S310 to S330.

At step S310, the enterprise platform obtains a funds transfer requirement including a plurality of accounts involved in the transfer of funds.

In the embodiment of the disclosure, the plurality of accounts involved in the funds in the circulation process may refer to accounts of a plurality of enterprises involved in the funds in the circulation process, or may refer to accounts of a plurality of individuals involved in the funds in the circulation process, which may be specifically determined according to actual needs, and is not limited herein. For example, company a is a package company, company b is a subcontracting company, company c is a material provider, and the funds transfer demand includes a demand made by company a for purchasing material (hereinafter referred to as funds transfer demand D), which requires an account related to company a, an account of company b, and an account of public and private third during the transfer process. For another example, a dispatch executive is dispatched to the company by dispatching a company's pent, and the funds transfer requirements include requirements set forth by the company's formates for issuing wages to the dispatch executive (hereinafter referred to as funds transfer requirements E), funds involving the company's pent account, and the dispatch executive's account during the transfer.

In step S320, the enterprise platform determines a sequence of funds circulation among the plurality of accounts according to the preset configuration information.

In step S330, the enterprise platform generates a plurality of transactions according to the order of the funds transfer and the plurality of accounts, wherein each transaction includes a plurality of accounts, and the plurality of accounts in each transaction includes a payment account and a collection account.

In the embodiment of the disclosure, the preset configuration information may be determined according to actual needs, for example, for the funds transfer requirement D, the transfer sequence of funds is an account of company a, an account of company b, an account of company c. At this time, two transactions may be generated, the first transaction including an account of company a and an account of company b, wherein the account of company a is a payment account and the account of company b is a collection account; the second transaction includes an account of company b and an account of company c, wherein the account of company b is a payment account and the account of company c is a collection account.

It should be noted that, in the embodiment of the present disclosure, the payment account refers to an account opened by an enterprise or an individual to be paid in a first commercial bank, and the collection account may be an account opened by an enterprise or an individual to be collected in the first commercial bank, or may be an account opened by an enterprise or an individual in another commercial bank, which is specifically determined according to actual needs, and is not limited herein.

Fig. 5a schematically illustrates a flow chart of extracting a transaction in a state to be executed according to an embodiment of the present disclosure. In some embodiments, as shown in fig. 5a, for N transactions generated according to the same funds transfer requirement among the multiple transactions, the nth transaction further includes a preamble transaction. Step S230 includes step S231.

In step S231, for the nth transaction, when the preamble transaction of the transaction is in the transaction completion state, the blockchain determines that the transaction is in the to-be-executed state, wherein N is greater than 1 and less than or equal to N, and N and N are both positive integers.

As previously described, for the funds transfer requirement D, the first transaction pays company a to company b and the second transaction (i.e., the nth transaction) pays company b to company c. The blockchain can find the first transaction from the account book according to the identification information of the first transaction when judging the state of the second transaction, judge whether the first transaction is in a transaction completion state, if so, determine that the second transaction is in a state to be executed, and if not, determine that the second transaction is in a state to be executed.

In the embodiment of the disclosure, the account book stores a plurality of transactions, and the plurality of transactions may be generated according to different funds circulation requirements, for example, one part of the plurality of transactions is generated according to the funds circulation requirement D, and the other part of the plurality of transactions is generated according to the funds circulation requirement E.

Alternatively, in the embodiment of the present disclosure, step S230 may be performed periodically according to a preset time interval, so that a batch operation can be performed on a plurality of transactions stored in the ledger and generated according to different funds circulation requirements. For example, in the first cycle, the first transaction set acquired through step S230 includes a transaction D1 generated according to the funds transfer demand D and a transaction E1 generated according to the funds transfer demand E. At this time, a first transaction instruction may be transmitted to the first commercial bank corresponding to the transactions d1 and e1 to enable the first commercial bank to perform a first transaction operation on the two transactions at step S240.

It should be noted that, in the embodiment of the present disclosure, each transaction may further include a subsequent transaction, so that a plurality of transactions generated according to the same requirement of funds circulation are related back and forth, so that a chain of funds in the circulation process is clear and transparent.

In some embodiments, the first transaction instructions include payment instructions, the first transaction operation includes a payment operation, and each transaction further includes a transaction amount. Fig. 5b schematically illustrates a flow chart of sending a first transaction instruction according to an embodiment of the present disclosure. As shown in connection with fig. 3 and 5b, step S240 includes step S241.

In step S241, the blockchain sends a payment instruction to the first commercial bank. The payment instructions are configured to: the method comprises the steps of enabling a first commercial bank to acquire a payment account, a collection account and a transaction amount of each transaction in a first transaction set, executing payment operation according to the payment account, the collection account and the transaction amount of each transaction in the first transaction set, and taking a result of the payment operation as an operation result of the first transaction operation.

In the embodiment of the disclosure, after sending the payment instruction to the first commercial bank, the blockchain may determine whether the payment instruction is sent successfully, and if so, the blockchain may update the status of a transaction corresponding to the payment instruction to be notified of the payment. Optionally, in the embodiment of the present disclosure, when the state of any transaction stored in the ledger changes, the blockchain may send a transaction state change notification to the enterprise platform; if not, the reason description of the transmission failure can be obtained and used for generating prompt information or carrying out subsequent operations such as re-extraction.

In the embodiment of the disclosure, a corresponding transaction adaptation module may be deployed in the first commercial bank, and the transaction adaptation module may be capable of acquiring a payment instruction, and may acquire, in response to the payment instruction, transaction content of a transaction corresponding to the payment instruction, that is, a payment account, a collection account, a transaction amount, and the like in the foregoing, from the first transaction set. The transaction adaptation module can also send the acquired transaction content to a core transaction module of the first commercial bank, and the core transaction module can pay from a payment account to a collection account according to the transaction amount, so that payment operation is executed.

Fig. 5c schematically illustrates a flow chart of updating the status of a transaction according to an embodiment of the present disclosure. As shown in fig. 5c, in some embodiments, step S250 includes steps S251 to S253.

In step S251, the blockchain determines whether the payment operation was successful. When the payment operation is successful, step S252 is performed, and when the payment operation is failed, a description of the reason for the failure may be obtained for generating a prompt message or performing a subsequent re-lifting operation.

In step S252, the blockchain updates the status of the transaction corresponding to the payment result to a payment complete status.

In step S253, the blockchain generates a display signal configured to cause the display device to display a current status of each of the plurality of transactions according to the display signal.

In the embodiment of the present disclosure, in addition to displaying the current status of each transaction, information related to status change may be displayed, for example, the initiator, the execution time, etc., which may be specifically determined according to actual needs, and is not limited herein.

Fig. 6 schematically illustrates a flow chart of sending a second transaction instruction according to an embodiment of the present disclosure. As shown in fig. 6, each of the plurality of transactions further includes a second commercial bank for performing a second transaction operation, and the transaction management method further includes steps S410 to S440.

In step S410, the blockchain extracts the second commercial bank for each transaction.

In embodiments of the present disclosure, the second transaction operation may include a confirmation operation corresponding to the first transaction operation, e.g., when the first transaction operation is a payment operation, the second transaction operation is a receipt confirmation operation; when the first transaction operation is a repayment operation, the second transaction operation is a repayment check operation, etc. Alternatively, in the embodiment of the present disclosure, the second transaction operation is a receipt confirmation operation, and the second commercial bank may be a commercial bank that performs a receipt in the transaction, that is, a commercial bank where a receipt account is located.

In step S420, the blockchain obtains a transaction in a payment completion state among the plurality of transactions to obtain a second transaction set.

In the disclosed embodiment, as described above, in step S252, after the first commercial bank successfully pays, the blockchain updates the status of the transaction to a payment complete status. Alternatively, in the embodiment of the present disclosure, step S420 may be periodically performed according to a preset time interval. When it is determined that a certain transaction among the plurality of transactions is in a payment completion state, step S430 and step S440 are performed to transmit a second transaction instruction to the corresponding second commercial bank, so that the second commercial bank can perform the second transaction operation on the plurality of transactions in batches.

In step S430, for each of the extracted second commercial banks, transactions for which a second transaction operation is performed by the second commercial bank are counted from the second transaction set to obtain a third transaction set corresponding to the second commercial bank.

In the embodiment of the disclosure, the plurality of transactions may be respectively executed by different second commercial banks, for example, the plurality of transactions includes a transaction X, a transaction Y, and a transaction Z, where the transaction X and the transaction Z are paid by a bank a to a bank B, and for the transaction X and the transaction Z, the bank a is a first commercial bank, the bank B is a second commercial bank, and the transaction X and the transaction Z form a third transaction set of the bank B. The transaction Y is paid by the bank B to the bank C, and for the transaction Y, the bank B is the first commercial bank, the bank C is the second commercial bank, and the transaction Y forms a third transaction set of the bank C.

Alternatively, in the embodiment of the present disclosure, for each second commercial bank, in addition to extracting the third transaction set, the total number of transactions, the total amount of transactions, and the like may be counted, specifically may be determined according to actual needs, and is not limited herein.

In step S440, for each third transaction set, the blockchain sends a second transaction instruction to a second commercial bank corresponding to the third transaction set. The second transaction instructions are configured to cause the second merchant bank to perform a second transaction operation in accordance with each transaction in the third transaction set and the second transaction instructions.

In some embodiments, the second transaction instruction includes a receipt confirmation instruction and the second transaction operation includes a receipt confirmation operation. Fig. 7 schematically illustrates a flow chart of sending a second transaction instruction according to an embodiment of the disclosure. As shown in conjunction with fig. 3 and 7, step S440 includes steps S441 to S445.

In step S441, the blockchain sends a collection confirmation instruction to the second commercial bank, the collection confirmation instruction configured to: the second commercial bank is caused to perform a collection confirmation operation to obtain and feed back the collection information of the collection account for each transaction in the third set of transactions.

In the embodiment of the disclosure, after sending the receipt confirmation instruction to the second commercial bank, the blockchain may determine whether the receipt confirmation instruction is sent successfully, and if so, the blockchain may update the status of a transaction corresponding to the receipt confirmation to be notified of the receipt confirmation; if not, the reason description of the transmission failure can be obtained and used for generating prompt information or carrying out subsequent operations such as re-extraction.

In an embodiment of the disclosure, the receipt confirmation instruction corresponds to the transaction in the third transaction set one by one, and the transaction adaptation module disposed in the first commercial bank may further obtain the receipt confirmation instruction, and may be capable of obtaining, in response to the receipt confirmation instruction, transaction content, such as a receipt account, of a transaction corresponding to the receipt confirmation instruction, from the third transaction set. The transaction adaptation module may further send the acquired transaction content to a core transaction module of the second commercial bank, so that the core transaction module may query a recent fund flowing in the collection account to perform a collection confirmation operation, and feed back the fund flowing to the transaction adaptation module. The transaction adaptation module may also feed back funds in the blockchain as cash flow information.

In step S442, the blockchain obtains the payment information fed back by the second commercial bank.

In step S443, the blockchain determines a transaction corresponding to the payment information based on the payment information.

In step S444, the blockchain determines whether the payment information matches the transaction amount in the transaction, i.e., whether the payment amount matches the payment amount. When the receipt information matches the transaction amount in the transaction, step S445 is performed, and when the receipt information does not match the transaction amount in the transaction, a corresponding prompt may be generated and notifying that the receipt confirmation fails.

In step S445, the status of the transaction is updated to the transaction completed status.

It should be noted that, in other embodiments, the second commercial bank may determine whether the collection is successful through the core transaction module, so that the second commercial bank may directly feed back the collection result, and the blockchain updates the status of a corresponding transaction according to the collection result fed back by the second commercial bank.

In the embodiment of the present disclosure, the foregoing method steps may be repeatedly executed according to a preset period, so that each transaction stored in the ledger includes: complete information flow of waiting-executing-payment completion-receipt confirmation-transaction completion, and the state of each transaction is associated with the actual operation of a commercial bank, thereby ensuring the consistency of the information flow and the fund flow. Moreover, by adopting the transaction management method of the embodiment of the disclosure, financial business fields such as total subpackage, purchasing, accounting of labor companies, wage distribution of enterprises and the like can be supported, and the application scene is wide.
