Detailed Description
FIG. 1 shows a system framework diagram of an embodiment of the present application. As shown in fig. 1, a blockchain system (otherwise 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.
The blockchain node 101 may be connected to one or more terminal devices 20, receive one or more transactions from the terminal devices 20, package the received transactions into blocks, and store the blocks in a blockchain; or further processing the received transaction, packaging the processed transaction into blocks and storing the blocks into a block chain. The terminal device 20 includes, but is not limited to, a personal computer, a mobile phone, and other various forms of electronic devices.
In the prior art, as shown in fig. 2, the transaction received by block link point 101 From terminal 20 may typically include a "From" field indicating a payment account, a "To" field indicating a collection account, a "Value" field indicating a transaction amount of digital french coins, and a "Data" field indicating other information included in the transaction. Illustratively, the "Data" field may also contain a sub-field "Time" indicating the Time of the transaction; the transaction Time indicated by the sub-field "Time" 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 when the terminal device 20 generates and transmits the transaction to the zone link point 101.
Accordingly, the blockchain network 10 may generally report a transaction To the monitoring system 30 when the transaction amount of the digital legal currency indicated by the "Value" field of the transaction is greater than a set Value, so that the monitoring system 30 analyzes whether the transaction is suspected of money laundering for the payment account indicated by the "From" field, the collection account indicated by the "To" field, and other related information of the transaction, To determine whether there is money laundering action for the payment account indicated by the "From" field and the collection account indicated by the "To" field of the transaction.
It will be appreciated that for a complete money laundering process, it is not usual to merely conduct one or more transactions between two accounts, but rather a large number of accounts are required to cooperate to conduct a high frequency of transactions. In the above technical solution, for the transaction in which the transaction quantity of the digital legal currency is larger than the set value and is reported to the monitoring system 30 by the blockchain network 10, even if the monitoring system 30 determines that the payment account and the collection account included in the transaction from the blockchain network 10 are target accounts participating in money laundering, it is difficult to further determine other accounts cooperating with the accounts to conduct money laundering.
In view of this, an embodiment of the present application provides a method and an apparatus for transaction management based on a blockchain, where a transaction stored in a blockchain includes one or more resource identifiers, and if the transaction is determined to be a supervised transaction, a certain number of other transactions initiated by a payment receiving account included in the transaction after a transaction time included in the transaction include mapping resource descriptions, and each resource identifier in the mapping resource description information is the same as each resource identifier in transaction resource description information included in the transaction. That is, transaction resource description information, mapping resource description information, payment accounts, and collection accounts contained by individual transactions that have been stored to the blockchain and determined to be supervised transactions may indicate transfer paths for digital legal coins contained by transactions suspected of being money laundering. In this manner, it is advantageous for the regulatory body to determine, after determining an account involved in money laundering, other accounts that cooperate with the account to conduct money laundering.
Illustratively, as in FIG. 3, for an account U1, suppose blockchain node 101 stores one transaction X to the blockchain n In the system, transaction time T1 and collection account U1, X are included n The Sub-field "Sub 1" contained in the contained field "Data" indicates X n The individual resource identifiers included in the transaction resource description information are a1, b1, b2, and X n A digital legal has been determined to be a regulated transaction because it contains a number of transactions for a digital currency indicated by the field "Value" that is greater than a set number or for other reasons. Then, the transaction supervision frequency P1 corresponding to U1 may be determined first, and the transaction supervision frequency P1 may be a preset initial value or a dynamic value dynamically updated according to each transaction in which U1 participates. Next, for each X transaction of the first P1 transactions initiated by U1 after time T1 p Block link point 101 is receiving X p Then, it is possible to do so at X p Adds mapping resource description information indicated by Sub-field "Sub 2",
the mapping resource description information indicated by "Sub 2" may include resource identifiers a1, b1, and b 2. Correspondingly, X containing mapping resource description information p Will be stored to the blockchain and will be determined to be a policed transaction.
Then, if transaction X n Middle ladleThe account containing the collection account U1 is determined by the regulatory system to be the account for which money laundering is present, and block link point 101 may first determine from the blockchain that the collection account is U1 and has been determined to be X for the regulated transaction n . Then according to X n The resource identifiers a1, b1 and b2 in the transaction resource description information indicated by the Sub-field "Sub 1" are included to determine the transaction xs mapping the resource identifiers a1, b1 and b2 in the resource information p . Correspondingly, except for U1, X n The "From" field included indicates the payment account, each X p The collection account, which is indicated by the "To" field included, indicates X for suspected money laundering n Transfer path of the digital legal note involved, i.e. X n The "From" field included indicates the payment account, each X p The collection accounts indicated by the "To" field included may each be an account that cooperates with U1 for money laundering; the regulatory agency/regulatory system 30 may then further combine other information pairs X n Each X p Performing an analysis from the X stored in the blockchain n Included is a "From" field indicating the payment account, each X p The "To" field is included To identify the account that cooperates with U1 for money laundering among the collection accounts.
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. 4 is a flowchart of a transaction management method based on a blockchain according to an embodiment of the present disclosure. The method may be performed by a blockchain link point 101 deployed with a blockchain based transaction management device in a blockchain network 10 as shown in fig. 1. As shown in fig. 4, the transaction management method based on blockchain may include at least the following steps 401 to 405: step 401, receiving a transaction to be stored to a blockchain; step 402, in a case that at least one first transaction is stored in the blockchain, determining a second transaction from each first transaction, where a collection account included in the first transaction is the same as a payment account included in the transaction, the first transaction is a determined supervised transaction, a transaction time included in the second transaction is a maximum value in the transaction time included in each first transaction, the second transaction further includes transaction resource description information, the transaction resource description information includes at least one resource identifier, and each resource identifier is used for uniquely identifying a preset number of digital legal coins in a corresponding hierarchical statistical unit; step 403, determining a cumulative amount of a third transaction stored in the blockchain, wherein a payment account included in the third transaction is the same as a payment account included in the transaction, and a transaction time included in the third transaction is greater than a transaction time included in the second transaction; step 404, determining the supervision frequency corresponding to the payment account included in the second transaction; step 405, when the supervision frequency is greater than the accumulated number, storing the transaction including mapping resource description information to a blockchain, and determining the transaction as a supervised transaction, where each resource identifier in the mapping resource description information included in the transaction is the same as each resource identifier in the transaction resource description information included in the second transaction.
First, in step 401, blockchain node 101 may receive a transaction from terminal device 20 to be stored to the blockchain. For convenience of description, the transaction received by the blockchain node 101 from the terminal device 20 is denoted as X hereinafter.
As described above, the "Data" field included in the transaction X may specifically include the Sub-field "Sub 1" indicating the transaction resource description information, and the transaction resource description information may specifically include one or more resource identifiers, where each resource identifier is used to uniquely identify a preset number of digital legal coins in the corresponding hierarchical statistical unit.
In the embodiment of the application, the total sum of the digital french coins respectively identified by the resource identifiers in the transaction resource description information included in the transaction X is the same as the transaction number of the digital french coins indicated by the "Value" field included in the transaction X.
Illustratively, a digital legal instrument is issued by a central bank, which may contain multiple levels of statistical units. In a more specific example, the digital legal tender is associated with a "Renminbi" issued by a central bank "The hierarchical statistical units include the same, such as hierarchical statistical units including "1 corner", "1 yuan", "10 yuan", "50 yuan", "100 yuan", and the like. Assuming that the transaction number of the digital legal tender indicated by the "Value" field included in the transaction X received from the terminal device 20 is "200", a plurality of resource identifications (similar to the crown word numbers of the renminbi) corresponding to the corresponding hierarchical statistical units may be included in the transaction resource description information indicated by the Sub-field "Sub 1" included in the transaction X. Exemplary, X p The transaction resource description information indicated by the Sub-field "Sub 1" may specifically include three resource identifiers a1, b1, and b2, wherein a1 corresponds to the hierarchical statistical unit "100 yuan", b1 and b2 correspond to the hierarchical statistical unit "50 yuan", and the sum of the digital legal coins respectively identified by a1, b1, and b2 is "200 yuan".
Next, in step 302, blockchain node 101 may determine, for transaction X received From terminal device 20, whether there are one or more first transactions (Y) in each transaction that has been stored in the blockchain and that has been determined To be a supervised transaction, each transaction Y containing a payment account indicated by the "From" field that is the same as a payment receiving account indicated by the "To" field contained by transaction X. When one or more transactions Y exist, a second transaction (Z) may be determined from each transaction Y, where the transaction Time indicated by the subfield "Time" included in the transaction Z is the maximum value among the transaction times indicated by the fields "Time" included in each transaction Y.
That is, the blockchain node may determine, for transaction X, that the payment account indicated by the "From" field contained in transaction X was last engaged as the recipient and was determined to be one of the transactions Z for which the transaction X was supervised, prior to the transaction Time indicated by the subfield "Time" of transaction X.
In one possible embodiment, if transaction Y, as described above, is not included in each transaction that has been stored to the blockchain and that has been determined to be a supervised transaction, blockchain node 101 may further determine whether the transaction amount of the digital currency indicated by the "Value" field included in transaction X is greater than a set Value. And under the condition that the transaction quantity of the digital legal currency indicated by the 'Value' field contained in the X is greater than a set Value, the transaction X is suspected of being washed money, the transaction X can be determined as a monitored transaction, and the transaction X is stored in the blockchain network. On the contrary, in the case that the transaction quantity of the digital legal currency indicated by the "Value" field included in the transaction X is not greater than the set Value, it indicates that the transaction X may be a normal transaction, and the transaction X may be directly stored in the blockchain.
Next, in step 403, blockchain node 101 may determine a cumulative number of third transactions stored in the blockchain, the third transactions including a payment account indicated by the "From" field that is the same as the payment account indicated by the "From" field included in transaction X, the third transactions including a transaction time that is greater than the transaction time included in transaction Z.
That is, if it is determined that the payment account indicated by the "From" field contained by transaction X was last engaged as a recipient before the transaction Time indicated by the subfield "Time" of transaction X, and was determined to be one transaction Z of the supervised transactions, it is further determined that the payment account indicated by the "From" field contained by transaction X is a cumulative number of transactions initiated by the initiator of the transaction after the transaction Time indicated by the subfield "Time" contained by transaction Z.
Further, in step 404, the block link point 101 may determine the supervision frequency corresponding to the payment account indicated by the "From" field included in the transaction Z.
In one possible embodiment, for transaction Z, if the payment account indicated by the "From" field included in transaction Z is not included in each of the already determined regulated transactions, the transaction regulation frequency corresponding to the payment account indicated by the "From" field included in transaction Z may be a preset initial value M greater than 0.
Accordingly, in another possible embodiment, after determining a transaction stored in the blockchain as an authorized transaction, the blockchain node 101 may dynamically update the transaction authorization frequency corresponding to each of the payment account and the collection account included in the transaction on the basis of the initial value. For example, if the account U1 appears in a transaction determined to be a supervised transaction, the supervision frequency corresponding to the U1 is updated according to a certain algorithm rule on the basis of M, the supervision frequency corresponding to the updated U1 is greater than the supervision frequency corresponding to the U1 before updating, and the supervision frequency corresponding to the updated U1 is recorded.
Further, in step 405, in a case that the supervision frequency corresponding to the second transaction is greater than the accumulated number of the third transaction, store the transaction X containing the mapping resource description information to the blockchain, and determine the transaction X containing the mapping resource description information as a supervised transaction.
The Sub-field "Sub 2" is included in the transaction X stored in the blockchain, and "Sub 2" indicates that each resource identifier in the mapping resource description information included in the transaction X is the resource identifier in the transaction resource description information indicated by the Sub-field "Sub 2" included in the transaction Z.
For example, referring to fig. 5, when the account U1 initiates a transaction Z to the account U2 as the recipient, the Sub-field "Sub 1" in the "Data" field included in the transaction Z indicates that the resource identifiers included in the transaction resource description information included in the transaction Z are a1, b1, and b 2. Then, if transaction Z is determined to be a supervised transaction, transactions X1, X2, X3, X4, X5 are initiated in sequence to accounts U3, U4, U5, U6, U7 for account U2 after the transaction Time indicated by sub-field "Time" in the "Data" field contained in transaction Z. Assuming that the transaction supervision frequency corresponding to U1 is 5, for the first 3 transactions X1, X2, X3 initiated by the account U2 after the transaction Time indicated by the Sub-field "Time" in the "Data" field contained in the transaction Z, the chunk link point 101 may add the Sub-field "Sub 2" indicating the mapping resource description information contained in it, and the field "Sub 2" contained in X1, X2, X3, indicating that the respective resource descriptions in the mapping resource description information contained in X1, X2, X3 are a1, b1, b2, in the fields "Data" contained in X1, X2, X3, respectively. Thereafter, X1, X2, X3 containing mapping resource description information may be further stored to the blockchain, and X1, X2, X3 may be determined as the supervised transaction.
It will be appreciated that transactions X1, X2, X3 due to storage to the blockchain have been determined to be supervised transactions. Therefore, similar processes as described above may be performed for transactions initiated by U3, U4, U5 based on similar processes as described above. For example, assuming that the supervision frequency corresponding to U4 is 2, each resource identifier in the transaction resource description information included in X1 is a2, b3, for transactions X6, X7 initiated by U4 to U8, U9 in sequence after the transaction time included in X1, the block chain node may add a subfield "Sub 2" to X6, X7 to indicate the mapping resource description information, and the subfields "Sub 2" added to X6, X7 indicate each resource identifier in the mapping resource description information included in X6, X7 to be a2, b3, respectively.
Accordingly, in one possible implementation, if the regulatory agency determines that an account is a target account for which money laundering behavior exists based on the individual transactions stored in the blockchain that have been determined to be regulated transactions, or otherwise, the regulatory agency may send a query request containing the target account to the blockchain network through the regulatory system. Then, the block chain link points can determine at least one target transaction from all the transactions stored in the block chain, wherein the target transaction is a determined supervised transaction, and a collection account of the target transaction is a target account; for each target transaction, determining at least one current transaction from the transactions stored in the block chain, wherein each resource identifier in mapping resource description information contained in the current transaction is the same as each resource identifier in transaction resource description information contained in the target transaction; the terminal device 20 or the monitoring system 30 is provided with each target transaction and each current transaction corresponding to each target transaction respectively.
In a more specific example, the query request containing the target account may be a transaction for invoking an intelligent contract, which may contain code for executing a predetermined transaction, which may include: determining at least one target transaction from each transaction stored in the blockchain according to a target account included in the transaction for calling the intelligent contract, wherein the target transaction is a determined supervised transaction, and a collection account of the target transaction is a target account; for each target transaction, determining at least one current transaction from the transactions stored in the block chain, wherein each resource identifier in mapping resource description information contained in the current transaction is the same as each resource identifier in transaction resource description information contained in the target transaction; the terminal device 20 or the monitoring system 30 is provided with each target transaction and each current transaction corresponding to each target transaction respectively.
Still referring to fig. 5, if account U2 is determined to be a target account for which money laundering behavior exists, target transaction Z may be first determined, and then current transactions X1, X2, X3 mapping respective resource identifiers in resource description information as a1, b1, b2 may be determined according to respective resource identifiers a1, b1, b2 in transaction resource description information included in target transaction Z, so as to provide Z1, X1, X2, X3 to supervisory system 30 or terminal device 20. Based on similar principles, the transactions X6, X7 may also be provided to the supervisory system 30 or the terminal device 20.
It is understood that accounts U1, U2, U3, U4, U5, U8 and U9 contained in Z1, X1, X2, X3, X6 and X7 can form a diversion path of the digital legal token as shown in FIG. 5.
It should be noted that, in the embodiment of the present application, the data structure of the transaction received by the block link point 101 from the terminal device and the data structure of the transaction stored in the block chain are exemplarily described, but each transaction may further include a field and a sub-field for indicating other information, and the names of each field and sub-field do not constitute a limitation to the technical solution provided in the embodiment of the present application.
