Detailed Description
The digital legal currency is issued by the central bank or an organization with the same/similar function as the central bank, which is beneficial to improving the effectiveness of the currency policy and can better support the development of the entity economy. Digital french coins refer to digital currencies recognized by countries throughout the world; at present, all countries in the world promote the research, development and application of their respective digital legal coins. Generally, for a transaction system (for convenience of description, referred to as a blockchain system in this application) developed based on blockchain technology and combined with actual business requirements, only one digital currency is usually circulated in one blockchain system.
As shown in fig. 1, in the embodiment of the present application, the blockchain systems 10 can communicate with each other to transmit corresponding data, so that two blockchain systems 10 using different digital french currencies as their currency can cooperate with each other to complete the cross-currency transaction.
A blockchain system (alternatively referred to as a blockchain network) 10 may include a plurality of blockchain nodes 101. The block link point 101 may be one or more computing devices with certain data storage capacity and certain computing capacity, such as a server.
A blockchain node 101 may be connected to one or more terminal devices, receive one or more transactions from the terminal devices, package the received transactions into blocks, and store the blocks in a blockchain located at the blockchain node 101; or further processing the received transaction, packaging the processed transaction into blocks, and storing the blocks in the block chain on the block link point 101. The terminal devices include, but are not limited to, personal computers, mobile phones, and other electronic devices in various forms.
In the embodiment of the present application, when an account U1 registered in one blockchain system a needs to perform a cross-currency transaction with an account U2 in another blockchain system B, U1 may initiate a transaction X1 in the blockchain system a. X1 may contain a recipient address pointing to the corresponding fund pool N1 registered in the first blockchain system of the second blockchain system to transfer a number of digital legal coins S1 (such as renminbi or a digital legal corresponding to renminbi) that are able to circulate in blockchain system a to fund pool N1. X1 may also indicate a transfer account U2 registered in blockchain system B; thus, the blockchain system B can execute a transaction Y1, and transfer a corresponding number of digital french coins S2 (such as U.S. dollars or digital french coins corresponding to U.S. dollars) that can be circulated in the second blockchain system from the fund pool N2 in the blockchain system B to U2, thereby completing the cross-currency transaction initiated from U1 to U2.
In the prior art, for a transaction across currencies, as shown in fig. 2, a blockchain node of one blockchain system may receive a transaction From its connected terminal device, which may typically include a "From" field indicating a payment account, a "To" field indicating a fund pool (such as one or more accounts) in the blockchain system that another blockchain system is registered, a "Value" field indicating a transaction amount of digital french coins circulating in the blockchain system, and a "Data" field indicating other information included in the transaction. The "Data" field may also include a sub-field "Time" indicating the transaction Time, which may be the Time when the payment account indicated by the "From" field initiates the transaction; in other words, the transaction Time indicated by the sub-field "Time" may be the Time at which the terminal device generates and transmits the transaction to the blockchain node of the blockchain system. Illustratively, the "Data" field may also contain a Sub-field "Sub 1" indicating an account to be transferred that is registered in another blockchain system.
Accordingly, the blockchain system may generally analyze the payment account indicated by the "From" field of a transaction in combination with other related information to determine whether the transaction is suspected of money laundering if the transaction amount of the digital legal currency indicated by the "Value" field of the transaction is greater than a set Value.
It will be appreciated that for money laundering by cross currency transactions, it is not usual to only carry out one or more transactions between two different currencies, but rather to require a high frequency of transactions between more currencies. In the above-described prior art, even if it can be determined that a certain cross-currency transaction executed in a certain blockchain system is suspected of money laundering, it is difficult to determine an account in another blockchain system that cooperates with a payment account included in the transaction to conduct money laundering.
In view of this, the embodiments of the present application provide a method and an apparatus for transaction management based on a blockchain, which are beneficial to locating an account in another blockchain system that cooperates with a payment account included in a transaction to perform money laundering after determining that the transaction stored in a certain blockchain system is suspected to be money laundering.
The block chain based transaction management method and apparatus provided in the embodiments of the present application are described in more detail below with reference to the accompanying drawings.
Fig. 3 is a flowchart of a transaction management method based on a blockchain according to an embodiment of the present disclosure. The method may be applied to any one of the blockchain systems 10 shown in fig. 1, and may be specifically executed by a blockchain link point 101 of the blockchain-based transaction management device deployed in the blockchain system 10. In the embodiment of the present application, for convenience of description, the blockchain system 10 to which the method based on the blockchain is applied in the embodiment of the present application is described as a second blockchain system using the second digital currency as the currency. As shown in fig. 3, the transaction management method based on blockchain may include at least the following steps 301 to 304: step 301, determining transaction resource description information included in a first transaction, a first transfer-in account registered in the second blockchain system, and a first supervision frequency corresponding to a payment account included in the first transaction, where the first transaction is stored in a first blockchain, the first blockchain is located on a blockchain link point included in the first blockchain system that uses a first digital legal token as currency, the transaction resource description information includes at least one resource identifier, and each resource identifier is used to uniquely identify a preset number of first digital legal tokens in a hierarchy statistical unit corresponding to the resource identifier; step 302, receiving a second transaction, wherein the second transaction comprises a payment account which is the first transfer-in account, and the second transaction also comprises a second transfer-in account which is registered in a third block chain system, and the third block chain system takes a third digital legal currency as currency; step 303, determining a second supervision frequency corresponding to the first transfer-in account when the first supervision frequency is greater than 0; step 304, storing the second transaction including mapping resource description information and the second supervision frequency to a second blockchain, where the second blockchain is located on a blockchain node included in the second blockchain system, and each resource identifier is included in the mapping resource description information.
First, in step 301, a second blockchain system may determine a first administration frequency corresponding to transaction resource description information included in a first transaction, a first transfer-in account registered in the second blockchain system, and a payment account included in the first transaction.
The first transaction is stored in a first block chain, the first block chain is located on a block chain node contained in a first block chain system which takes a first digital legal token as circulation currency, the transaction resource description information contains at least one resource identifier, and each resource identifier is used for uniquely identifying a preset number of first digital legal tokens in a corresponding hierarchical statistical unit.
In the embodiment of the application, the sum of the first digital french coins respectively identified by each resource identifier in the transaction resource description information included in the first transaction is the same as the transaction quantity of the first digital french coins included in the first transaction.
Illustratively, a first digital legal instrument is issued by a central bank, which may contain a plurality of hierarchical statistical units. For example, the first digital legal currency and the "rmb" issued by the central bank may include at least a hierarchy statistic unit such as "1 corner", "1 yuan", "10 yuan", "50 yuan" and "100 yuan". Assuming that the first transaction X1 stored in the first blockchain contains the transaction amount of the first digital legal currency of "200 yuan", the transaction resource description information contained in X1 may contain a plurality of resource identifiers (similar to the crown numbers of rmb) corresponding to corresponding hierarchical statistical units. For example, the trading resource description information included in X1 may specifically include three resource identifiers a1, b1, and b2, where a1 corresponds to a hierarchical statistical unit "100 yuan", b1 and b2 correspond to a hierarchical statistical unit "50 yuan", and a total of the first digital french coins respectively identified by a1, b1, and b2 is "200 yuan".
For example, referring to fig. 4, for the account U1 registered in the first blockchain system a, the field "From" included in the cross-currency transaction X1 (i.e., the first transaction X1) stored to the first blockchain indicates that the payment account is U1, the Sub-field "Sub 1" in the field "Data" included in X1 indicates that the transfer-in account U2 registered in the second blockchain system B, the Sub-field "Sub 2" in the field "Data" included in X1 indicates that the supervision frequency P1 corresponding to U1, and the Sub-field "Sub 3" in the field "Data" included in X1 indicates that the respective resource identifications a1, B1, B2 in the transaction resource description information included in X1.
It is To be understood that X1 may also include a field "To" indicating that the second blockchain system B corresponds To the fund pool N1 registered in the first blockchain system a; x1 may also include a field "Value" indicating the transaction amount for the first digital french currency; the field "Data" may also contain a sub-field "Time" indicating the transaction Time T1.
Optionally, the field "Data" included in X1 may further include a Sub-field "Sub 4" indicating each resource identifier in the mapping resource information included in X1.
The transaction supervision frequency P1 corresponding to the payment account U1 included in the first transaction X1 may be a preset initial value added by the blockchain system a in the X1 when the number of first digital legal coins included in the first transaction X1 initiated by the blockchain system a in the U1 is greater than a set value, or when the first transaction X1 initiated by the U1 needs to be supervised for other reasons, or a dynamic value dynamically updated according to each transaction in which the U1 participates.
It should be appreciated that the second blockchain system B may be in communication with the first blockchain system a, i.e., the blockchain system B may query the first blockchain at the blockchain link point comprised by the blockchain system a to determine information about the first transaction X1 stored on the first blockchain, such as the information comprised by the first transaction as described in step 301.
As described above, after the second blockchain system queries the first transaction X1, the second blockchain system can correspondingly determine the transaction amount M2 of the second digital legal coin S2 according to the transaction amount M1 of the first digital legal coin S1 contained in X1. The second blockchain system may then execute a transaction Y1 to transfer the second digital legal instrument of transaction number M2 from the fund pool N2 in the second blockchain system B to U2S 2. Thereby completing a cross-currency transaction.
Next, at step 302, the second blockchain system may receive a second transaction.
The payment account included in the second transaction is a first transfer-in account included in the first transaction, the second transaction also includes a second transfer-in account registered in a third block chain system, and the third block chain system takes a third digital legal currency as currency.
It will be appreciated that the second transaction received by the second blockchain system may be from a corresponding terminal device.
Still referring to fig. 4, for the second blockchain system B, the first transfer account U2, contained in the first transaction X1, may initiate a cross-currency transaction X2 (i.e., the second transaction X2) directed to account U3 registered in blockchain system C as a payment account at time T2 after time T1, which blockchain system B may receive the second transaction X2.
The second transaction X2 received by the second blockchain system B may include a payment account U2, a fund pool N3 registered in the second blockchain system by the third blockchain system C, a transaction amount M3 of the second digital legal instrument, a transaction time T2, a second transfer-in account U3 registered in the third blockchain system C, and transaction resource description information formed by resource identifiers a1, B1, and B2. Similar to the first digital french coin, a1, B1 and B2 are respectively used for uniquely identifying the second digital french coins with preset number in the corresponding hierarchical statistical unit.
Next, in step 303, the second blockchain system may determine a second supervision frequency corresponding to the first transfer-in account when the first supervision frequency included in the first transaction is greater than 0.
In a more specific example, the difference between a first regulatory frequency corresponding to a payment account involved in a first transaction and a second regulatory frequency corresponding to a first transfer account involved in the first transaction may be 1.
In another more specific example, the second supervision frequency corresponding to the first transfer-in account included in the first transaction may be a preset value or a dynamic value that is dynamically updated according to the transaction in which the first transfer-in account participates.
Still referring to FIG. 4, if the first administration frequency P1 corresponding to the payment account U1 contained in the first transaction X1 is greater than 0, indicating that the second transaction X2 initiated by the first transfer account U2 contained in the first transaction X1 needs to be administered, a second administration frequency P2 corresponding to U2 may be determined.
In one possible embodiment, in the case that the first supervision frequency corresponding to the payment account included in the first transaction is equal to 0, the second blockchain system may further determine whether the transaction amount of the second digital legal currency included in the second transaction is greater than a corresponding set value; in the case that the transaction amount of the second digital currency included in the second transaction is greater than the corresponding set value, the second blockchain system may further determine a third supervision frequency corresponding to the first transfer-in account included in the first transaction (i.e., the payment account included in the second transaction), and store the second transaction including the third supervision frequency in the second blockchain. At this time, the third supervision frequency may be a preset value or a dynamic value dynamically updated according to the transaction in which the first transfer-in account participates.
Accordingly, in another possible implementation, in the case that the transaction number of the second digital currency included in the second transaction is smaller than or equal to the corresponding set value, the second blockchain system may directly store the second transaction received by the second blockchain system to the second blockchain.
Thereafter, at step 304, the second blockchain system may store a second transaction containing the mapped resource description information, a second supervised frequency, to the second blockchain.
The second blockchain is located on a blockchain node included in the second blockchain system, and each resource identifier is included in the mapping resource description information.
Still referring to fig. 4, the second blockchain system B may add a second supervision frequency P2 corresponding to the first transferred-in account indicated by the Sub-field "Sub 2" (i.e., the payment account U2 included in X2) in the second transaction X2, and add mapping resource description information indicated by the Sub-field "Sub 4" in the second transaction X2, where each resource description included in the mapping resource description information is a1, a B1, and a B2 in the transaction resource description information included in the first transaction X1.
In a possible embodiment, before performing step 304, the second blockchain system may further perform the following steps a to c:
step a, determining the transaction time contained in the first transaction stored in the first blockchain.
Illustratively, the sub-field "Time" in the "Data" field contained in the first transaction X1 may be queried for the transaction Time T1.
And b, determining the accumulated quantity of the third transaction stored in the second blockchain.
The payment account contained in the third transaction is the same as the payment account contained in the second transaction, and the transaction time contained in the third transaction is greater than the transaction time contained in the first transaction. That is, it is determined that the first transfer account U2, comprised by the first transaction X1, is a cumulative number of transactions initiated as payment accounts after time T1.
And c, determining whether the second transaction needs to be supervised according to the accumulated quantity.
For example, a maximum supervision frequency may be preset, and when the accumulated amount reaches the preset maximum supervision frequency, it is determined that the second transaction does not need to be supervised.
Accordingly, the second blockchain system may perform step 304 upon determining that the second transaction it receives requires supervision. Conversely, if it is determined that the second transaction it receives does not require policing, the second transaction it receives may be stored directly to the second blockchain.
Correspondingly, in a possible implementation manner, if the monitoring mechanism determines that a certain transaction is suspected of money laundering, each target resource identifier in the transaction resource description information included in the transaction can be acquired, so that an inquiry request including each target resource identifier is sent to the blockchain system.
In this way, after receiving the query request including at least one target resource identifier, the second blockchain system may determine at least one target transaction from the transactions stored in the second blockchain, and provide the target transactions to the regulatory agency or the corresponding terminal device, where each resource identifier in the mapping resource description information included in the target transaction is the same as each target resource identifier.
In a more specific example, the query request including at least one target resource identifier may be a transaction for invoking a smart contract, which may include code for executing a predefined transaction, which may include: determining at least one target transaction from the transactions stored in the second blockchain, wherein each resource identifier in mapping resource description information contained in the target transaction is the same as each target resource identifier; respective target transactions are provided.
Still referring to fig. 4, if the transaction X1 is determined to be a cross-currency transaction involving suspected money laundering, i.e. the payment account U1 contained in the transaction X1 is determined to be an account for which money laundering action exists, then the resource identifiers a1, B1, B2 in the transaction resource description information contained in X1 may be obtained, and then an inquiry request containing the resource identifiers a1, B1, B2 is sent to the second blockchain system, and the second blockchain system B may inquire the second transaction X2 mapping the resource identifiers a1, B1, B2 in the resource description information from the second blockchain. Accordingly, after the X2 is provided to the regulatory agency or corresponding regulatory system, the agency can determine that the first digital legal currency contained in the suspected money laundering transaction X1 may be U1-U2-U3.
