[0033] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Figure 1 This is a system architecture applicable to the embodiments of the present invention. Figure 1 As shown, the system architecture may include multiple clients 100 and a blockchain system 200. The client 100 may be connected to the blockchain system 200 via a network.

[0035] The multiple clients 100 may be clients used by different merchants, different banking institutions, and different users, and the blockchain system 200 may be accessed through the clients 100.

[0036] It should be noted that the above Figure 1 The structure shown is only an example and is not limited to this embodiment of the present invention.

[0037] Based on the above description, Figure 2 The process of a transaction management method based on associated transaction rules provided by an embodiment of the present invention is exemplarily shown. The process can be executed by a transaction management device based on associated transaction rules.

[0038] like Figure 2 As shown in the figure, the process specifically includes:

[0039] Step 201, obtaining a fund transaction request.

[0040] The fund transaction request may include a fund transaction and a fund ID with a transaction rule. Each fund transaction carries a transaction rule to verify whether the subsequent fund transaction is valid.

[0041] Step 202: Determine a set of associated transactions related to the fund transaction request from a block in the blockchain system according to the fund ID.

[0042] Specifically, since each fund transaction is stored in a chain-structured block of the blockchain system, the associated transaction set related to the fund transaction request can be determined from the block through the fund ID. The associated transaction set includes all fund transactions related to the fund ID, that is, the transaction path from the source to the current transaction. Each fund transaction in the associated transaction set carries its own transaction rules.

[0043] Step 203, determining whether the fund transaction request is valid according to the transaction rules carried by each fund transaction in the associated transaction set; if so, processing the fund transaction carrying the transaction rules and writing it into the block of the blockchain system.

[0044] When the associated transaction set related to the capital transaction request is obtained, it is possible to determine whether the capital transaction request is valid according to the transaction rules carried by each capital transaction in the associated transaction set. If it is valid, the capital transaction can be processed. When determining whether the capital transaction request is valid, it is mainly to determine whether the capital transaction request complies with the transaction rules carried by each capital transaction in the associated transaction set. If it complies, the capital transaction request is determined to be valid. If it does not comply, the capital transaction request is determined to be invalid.

[0045] When the current confirmation fund transaction request is valid, the fund transaction carrying the transaction rules can be processed according to the source of the fund transaction request.

[0046] Specifically, the fund transaction carrying the transaction rules is processed according to the source of the fund transaction request. If the source of the fund transaction request is the blockchain system, the fund transaction request operation is executed, and the fund transaction carrying the transaction rules is written into the block of the blockchain system. If the source of the fund transaction request is the bank system, the transaction flag is set to success, so that the bank system executes the transfer operation and writes the fund transaction carrying the transaction rules into the block of the blockchain system. The bank system can query the transaction flag through the smart contract query interface. When the transaction flag is queried as successful, the transfer operation continues, otherwise the transfer operation is terminated.

[0047] After the financial transaction carrying the transaction rules is processed, the processed financial transaction can be written into the block of the blockchain system.

[0048] It should be noted that the above-mentioned fund management can be divided into two parts: fund injection and fund use. When the fund transaction request is a fund injection transaction request, the transaction rules carried by each fund transaction in the above-mentioned related transaction set may include rules restricting fund recipients or targeted quantitative injection rules or batch injection rules.

[0049] For example, a request for funds injection in a blockchain system or a bank system is sent to the fund management blockchain system. The fund injection smart contract determines whether the fund injection request is valid through preset conditions (transaction rules). For a request for funds injection in the blockchain system, if the request is valid, the fund transfer request in the system will continue to be executed; otherwise, the fund injection will fail. For a request for funds injection in the bank system, the bank system requests the smart contract query interface, and if the transaction mark is successful, the transfer operation will continue; otherwise, the transfer operation will be terminated.

[0050] The above preset condition judgment can be divided into the following situations:

[0051] 1. Restrictions on recipients of funds

[0052] Regarding the restriction of fund recipients, one method is that the address of the recipient who meets the fund acceptance conditions is first registered in the smart contract, and then the recipient of the fund injection request is determined to be registered in the contract. Another method is that the smart contract requests an external system to obtain whether the recipient of the fund injection request meets the fund acceptance conditions from the external system.

[0053] 2. Targeted and quantitative delivery

[0054] For targeted and quantitative capital injection. First, for each capital injection, the capital injection conditions must be preset. When making a capital injection request, trace back the injection transactions from the initial injection to the current injection, and judge according to the preset injection range and injection quantity of the injection request in the path. If the injection request meets all the conditions on the path, it means that the injection request is successful; otherwise, it is marked as failed.

[0055] 3. Release in batches

[0056] For batch funding, first register the funding batch, time and quantity in the contract, and set the batch timer in the contract. When the timer of the current batch arrives, the funding request flag for this batch will be valid.

[0057] When the fund transaction request is a fund use transaction request, the transaction rules carried by each fund transaction in the associated transaction set may include rules restricting merchants that accept funds or rules restricting the amount of funds used.

[0058] For example, a request for the use of funds in a blockchain system or a bank system is sent to the fund management blockchain. The fund use smart contract traces the transaction from the initial release of funds to the final recipient of the funds based on the source of the fund use request. It determines whether the fund use request is valid based on the restrictions on the use of the release transaction. For the release request in the blockchain system, if the fund use request is valid, the fund transfer request in the system will continue to be executed; otherwise, the fund use request will fail. For the fund use request through the bank system, the bank system requests the smart contract query interface, and if the transaction mark is successful, the transfer operation will continue; otherwise, the transfer operation will be terminated.

[0059] Regarding restrictions on the use of trading pairs, they can be divided into the following situations:

[0060] 1. Restricting merchants who accept funds

[0061] Regarding restrictions on merchants accepting funds, one method is to first register the address and type of the merchant accepting funds in the smart contract, and the fund use contract makes a judgment based on the registered information. The second method is that the fund use contract requests the external system contract to obtain whether the merchant accepting funds is valid from the external system.

[0062] 2. Limit the amount of funds used

[0063] For limiting the amount of funds used, determine whether the amount of funds used matches the amount restricted in the conditions or the amount of accumulated use. If they match, the fund use record is valid.

[0064] In order to better explain the embodiment of the present invention, the process of transaction management based on associated transaction rules will be described below through a specific implementation scenario.

[0065] like Figure 3 As shown, this embodiment is based on the digital currency system to achieve targeted placement and targeted use of agricultural subsidy funds. A sum of money goes through two intermediary institutions from the initial placement institution to the terminal recipient. The restriction condition is to limit the terminal recipient to certain fixed farmers and limit the acceptance merchants to designated agricultural tool sales merchants.

[0066] The specific steps are as follows:

[0067] 1. According to the subsidy policy, the digital currency wallet address and subsidy amount information of the subsidized farmers are imported from the external system into the fund placement smart contract.

[0068] 2. Import the digital wallet address and merchant type of the designated merchant from the external system into the fund placement smart contract.

[0069] 3. The first-level placement agency creates an initial placement request A, and the receiving agency is the second-level placement agency. The placement request A contains the rules: <list of third-level placement agencies, list of merchants using funds>.

[0070] 4. The initial release request is sent to the digital currency system. The fund release smart contract verifies the releaser, recipient, and quantity of the release request. If the verification is successful, the transaction request A is stored in the underlying digital currency blockchain and the transfer transaction continues.

[0071] 5. The secondary distribution institution sends a secondary distribution request B to the digital currency system. The recipient of the distribution request B is the tertiary distribution institution. The rules contained in the distribution request B are: <list of assisted farmers, list of merchants using funds>.

[0072] 6. The capital release smart contract obtains the initial release request A on the transaction path according to the release request B, obtains the list of third-level release institutions from the conditions of the release request A, and determines whether the recipient of the second-level release request B is in the list of third-level release institutions. If so, the transaction request B is stored in the bottom layer of the digital currency blockchain and the transfer transaction continues; otherwise, the release is terminated and an alarm is sent to the upper-level audit system.

[0073] 7. The third-level release institution sends the final release request C to the digital currency system. The recipient of the release request is the assisted farmers, and the conditions included in the release request C are the <list of merchants using funds>.

[0074] 8. The capital injection smart contract obtains transactions A and B on the path from the initial injector A to C based on the injection request C.

[0075] 9. Determine whether the recipient of the release request C meets the conditions of request B - the list of assisted farmers; determine whether the sender of the release request C meets the conditions of request A, the list of three-level release institutions. If all meet, store the release request C at the bottom layer of the digital currency blockchain and continue the transfer transaction; otherwise, terminate the release and alert the upper-level audit system.

[0076] 10. After the release request C is successful, the subsidy funds finally reach the digital currency wallet of the assisted farmer. After receiving the digital currency of the subsidy, the assisted farmer can use the digital currency to purchase agricultural tools at designated agricultural tool sales merchants.

[0077] 11. The farmer's digital currency wallet sends funds using request X to the digital currency system, and the recipient of request X is the merchant.

[0078] 12. The fund usage smart contract obtains the release transaction paths A, B, and C involved in the usage request X from the underlying digital currency blockchain.

[0079] 13. Determine whether the merchant receiving the fund use request X meets the conditions for placing transaction A - the fund use merchant list; determine whether the merchant receiving the fund use request X meets the conditions for placing transaction B - the fund use merchant list; determine whether the merchant receiving the fund use request X meets the conditions for placing transaction C - the fund use merchant list. If all conditions are met, the transfer transaction is executed and the purchase of agricultural tools is successful; otherwise, the transaction is terminated and an alarm is sent to the upper-level audit system.

[0080] 14. The agricultural implement sales merchants can use their digital currency wallets to convert the accepted digital currencies into electronic currencies. This process ends.

[0081] It should be noted that the embodiments of the present invention can also be applied to scenarios such as poverty alleviation, public welfare and charity, and special funds.

[0082] The above embodiment shows that by obtaining a capital transaction request, the capital transaction request includes a capital transaction carrying transaction rules and a capital ID, and according to the capital ID, a set of associated transactions related to the capital transaction request is determined from the block of the blockchain system, and according to the transaction rules carried by each capital transaction in the associated transaction set, whether the capital transaction request is valid is determined; if so, the capital transaction carrying the transaction rules is processed according to the source of the capital transaction request. When a capital transaction request is received, its associated capital transaction set can be traced from the chain-structured block of the blockchain, and according to the transaction rules contained in the associated capital transaction set, whether the current capital transaction request is valid is determined, thereby determining whether the current capital transaction is successful, so that the capital transaction is easy to manage, the capital transaction situation can be traced, and the capital security is determined.
