[0071] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0072] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0073] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0074] As the complexity of channel agent settlement business continues to increase, the settlement process needs to be completed through the mutual cooperation and data sharing of three settlement scenarios: real-time settlement of in-memory database, quasi-real-time settlement of relational database and statistical settlement based on Hadoop. Since the three settlement scenarios rely on the billing data of the accounting system, and in the actual production and operation process, the billing data will have multiple versions of adjustments and changes, resulting in a many-to-many relationship between the settlement scenario and the billing data. That is: one version of billing data corresponds to multiple settlement scenarios; one settlement scenario will use multiple versions of billing data. In addition, the accounting system, real-time settlement system, quasi-real-time settlement system and statistical settlement system are in a distributed system management mode, each independent and mutually cooperative. In this multi-scenario, multi-version distributed settlement system for agents, the common processing strategy is to establish a more centralized unified settlement file version management platform, and the settlement system needs to uniformly apply for settlement files from the platform to realize the settlement work of the agents. However, the centralized settlement file version management only focuses on the changes in file versions and the uniformity of data, but cannot improve the flexibility, autonomy of settlement scenarios and the data collaboration between settlement systems. Especially in view of the current flexible and changeable reality of Internet marketing, higher technical requirements are put forward for agents' settlement in terms of multi-scenario, multi-dimensional, multi-version and mutually coordinated distributed settlement such as real-time, quasi-real-time and statistical settlement.

[0075] In order to solve the above technical problems, the embodiment of this application proposes the following technical ideas: adding blockchain technology to the existing settlement system, and establishing a distributed settlement bill multi-version consistency control method between the accounting system, real-time settlement system, quasi-real-time settlement system and statistical settlement system. Using blockchain technology to manage the distributed global state, the global state is used between heterogeneous systems to achieve innovative functions such as consistency management of bill multi-versions, sharing of settlement results, and multi-scenario collaboration.

[0076] Figure 1 Schematic diagram of an application scenario of the method for processing the settlement of bill data provided in the embodiment of the present application. Figure 1 As shown, the application scenario includes: an accounting system 101, a real-time settlement system 102, a quasi-real-time settlement system 103, a statistical settlement system 101 and a blockchain 105.

[0077] It is understandable that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the object identification method. In other feasible implementations of the present application, the above architecture may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently, which can be determined according to the actual application scenario and is not limited here. Figure 1 The components shown may be implemented in hardware, software, or a combination of software and hardware.

[0078] In a specific implementation process, the financial system 101 may run on a specific hardware device, such as a computer or a server.

[0079] The real-time settlement system 102 may be run on a specific hardware device, such as a computer or a server.

[0080] The quasi-real-time settlement system 103 may be run on a specific hardware device, such as a computer or a server.

[0081] The statistical settlement system 104 can be run on a specific hardware device, such as a computer or a server.

[0082] Blockchain 105 can run on a blockchain router, a blockchain phone, or a hardware wallet.

[0083] The financial system 101 sends any version of the bill data to the financial node in the blockchain 105. The financial node in the blockchain 105 updates the global status data according to the bill data, and broadcasts the updated global status data in all nodes of the blockchain to complete synchronization; the real-time settlement system 102, the quasi-real-time settlement system 103 or the statistical settlement system 104 obtains the global status data corresponding to the current version of the bill data through the corresponding settlement nodes in the blockchain 105. If the current version of the bill data is determined to be the latest version, the settlement procedure is started according to its own settlement rules to obtain the settlement file; when the real-time settlement system 102, the quasi-real-time settlement system 103 or the statistical settlement system 104 verifies that the hash value of the bill attribute field in the current version of the bill data is consistent with the hash value of the bill attribute field in the bill data used in the settlement processing of each system, the settlement information corresponding to the settlement file is sent to the corresponding settlement node in the blockchain 105; the corresponding settlement nodes in the blockchain 105 update the global status data in turn according to the settlement information corresponding to the different settlement files received, and broadcast the updated global status data in all nodes of the blockchain 105 to complete synchronization.

[0084] The method for settlement processing of bill data provided in this application is intended to solve the above technical problems of the prior art.

[0085] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0086] based on Figure 1 In the application scenario shown, an embodiment of the present application provides a method for settlement processing of bill data. Figure 2 Flow chart of the method for processing the settlement of bill data provided in the embodiment of the present application. Figure 2 As shown, the settlement processing method of the bill data includes:

[0087] S201: The financial system sends any version of bill data to a financial node of the blockchain, where the blockchain includes multiple nodes and the financial node is one of the multiple nodes.

[0088] Among them, the accounting system will continuously generate and output multiple versions of bill data A1-An for agent settlement, A1 represents the first version of the bill, and An represents the nth version of the bill; the financial system is an operating system established by an enterprise or organization based on its own needs and goals, which is used to reflect, supervise, control and coordinate business activities and financial activities.

[0089] The corresponding nodes in the blockchain include computers or other devices connected to the network, such as mobile phones or mining machines. The financial nodes in the blockchain are a special type of blockchain node, which is mainly responsible for processing transactions and data related to accounts.

[0090] S202: The financial node of the blockchain updates the global status data according to the bill data, and broadcasts the updated global status data in all nodes of the blockchain to complete synchronization.

[0091] Among them, different global status data corresponding to different versions of bill data can be expressed as SA1-SAn; global status data includes: status identifier (Base64), file name (String), file access path (String), bill complete metadata (JSON), bill Entity object metadata (JSON), version hash value (SM3), real-time settlement status (Bool), real-time settlement file list (JSON), real-time settlement file access address (JSON), quasi-real-time settlement status (Bool), quasi-real-time settlement file list (JSON), quasi-real-time settlement file access address (JSON), statistical settlement status (Bool), statistical settlement file list (JSON) and statistical settlement file access address (JSON).

[0092] Among them, in the blockchain network, the updated global state data is broadcast between the nodes of the blockchain through P2P network transmission, and the consistency of the updated global state data between the nodes of the blockchain is guaranteed by PBFT (Practical Byzantine Fault Tolerance).

[0093] Specifically, the financial node of the blockchain updates the bill field information in the global status data according to the bill data, wherein the updated content in the global status data is all field information in the bill field information except the status identifier.

[0094] S203: Any settlement system obtains global status data corresponding to the current version of the bill data through the corresponding settlement node in the blockchain, where the settlement node is one of the multiple nodes.

[0095] Among them, the corresponding settlement nodes in the blockchain include computers or other devices connected to the network, such as mobile phones or mining machines.

[0096] Specifically, any settlement system sends a request for global status data to the corresponding settlement node in the blockchain, and the corresponding settlement node in the blockchain sends the global status data corresponding to the current version of the bill data to any settlement system based on the request for the global status data.

[0097] In one implementation, any settlement system sends a request for global state data to the corresponding settlement node in the blockchain at a first preset time interval. If the global state data is updated in the blockchain, the updated global state data will be broadcast to the corresponding settlement node in the blockchain and cached in the corresponding settlement node in the blockchain; the corresponding settlement node in the blockchain sends the cached updated global state data to any settlement system. Optionally, the first preset time may be 10 minutes.

[0098] Among them, the request sent by any settlement system to the corresponding settlement node in the blockchain is implemented through an API interface call.

[0099] In another implementation, any settlement system sends a request for global state data to the corresponding settlement node in the blockchain every first preset time. If the global state data is not updated in the blockchain, the corresponding settlement node in the blockchain sends an empty response or a message indicating no update to any settlement system. Optionally, the first preset time may be 10 minutes.

[0100] S204: Any settlement system determines whether the current version of the billing data is the latest version; if it is determined that the current version of the billing data is the latest version, any settlement system starts the settlement procedure according to its own settlement rules to obtain a settlement file.

[0101] Among them, the settlement rules of any settlement system itself may include: the sender and receiver of the settlement, which costs are to be settled or when to settle.

[0102] In one implementation, any settlement system determines whether the hash value of the current version of the bill data obtained is consistent with the hash value of the previously obtained version of the bill data. If the hash value of the current version of the bill data obtained is consistent with the hash value of the previously obtained version of the bill data, it is determined that the current version of the bill data is the latest version. Then, any settlement system starts the settlement procedure according to its own settlement rules to obtain the settlement file.

[0103] The hash value is a mapping of the input data type that is difficult to compare into a number of fixed length after being processed by a specific calculation function. The main characteristics of the hash value include: fixed output length, non-random results, sensitive to input changes, and one-way irreversibility. Therefore, even if only one bit of the original data is modified, the final hash value will be very different.

[0104] In another implementation method, any settlement system determines whether the hash value of the current version of the bill data obtained is consistent with the hash value of the previously obtained version of the bill data. If the hash value of the current version of the bill data obtained is inconsistent with the hash value of the previously obtained version of the bill data, it is determined that the current version of the bill data is not the latest version, and the latest version of the bill data is requested from the financial system, and the settlement program is started according to its own settlement rules to perform settlement processing on the latest version of the bill data to obtain a settlement file.

[0105] S205: Any settlement system verifies whether the hash value of the bill attribute field in the current version of the bill data is consistent with the hash value of the bill attribute field in the bill data used by the settlement system during settlement processing; if they are consistent, the settlement information corresponding to the settlement file is sent to the corresponding settlement node in the blockchain.

[0106] The bill attribute fields include: bill complete metadata and bill Entity object metadata.

[0107] In another implementation method, if the hash value of the bill attribute field in the current version of the bill data is inconsistent with the hash value of the bill attribute field in the bill data used in the settlement processing of the settlement system, new global status data is inserted in any settlement system, and the settlement procedure is started according to the settlement rules of any settlement system to obtain an updated settlement file, and the settlement information corresponding to the settlement file is sent to the corresponding settlement node in the blockchain; the corresponding settlement node in the blockchain updates the new global status data according to the settlement information corresponding to the received settlement file, and broadcasts the updated new global status data in all nodes of the blockchain to complete synchronization.

[0108] Among them, the status identifier, file name and file access path in the bill field information in the new global status data are consistent with the original global status data, and the bill complete metadata, bill Entity object metadata and bill version hash value are updated according to the bill data at the time of settlement.

[0109] S206: The corresponding settlement node in the blockchain updates the global status data according to the settlement information corresponding to the received settlement file, and broadcasts the updated global status data in all nodes of the blockchain to complete synchronization.

[0110] Among them, the corresponding settlement node in the blockchain updates the settlement field in the global state data according to the settlement information corresponding to the received settlement file.

[0111] Among them, when the corresponding settlement node in the blockchain receives the settlement information corresponding to the settlement file, the corresponding settlement node in the blockchain first verifies the integrity and validity of the settlement information. If the verification passes, the corresponding settlement node in the blockchain will update the global status data according to the settlement information.

[0112] In summary, in this embodiment, first, any settlement system is used to determine whether the current version of the bill data is the latest version; and then any settlement system is used to verify whether the hash value of the bill attribute field in the current version of the bill data is consistent with the hash value of the bill attribute field in the bill data used by the settlement system for settlement processing. The global status data corresponding to the bill data is verified twice, which strictly ensures a high degree of consistency in settlement dimensions and calibers in settlement scenarios and many-to-many bill data, thereby avoiding the situation where the same version of bill data has inconsistent settlement results in different settlement scenarios.

[0113] In an embodiment of the present application, based on the above embodiment, this embodiment focuses on describing the different processes for updating the global status data when any settlement system is a real-time settlement system, a quasi-real-time settlement system, and a statistical settlement system.

[0114] In an example of the present application, the settlement system is a real-time settlement system; the corresponding settlement node in the blockchain is a real-time settlement node; the settlement information corresponding to the settlement file includes: real-time settlement status, real-time settlement file list and real-time settlement file access address. Accordingly, step S206 specifically includes: the corresponding real-time settlement node in the blockchain writes back the real-time settlement field in the global state data according to the real-time settlement status, real-time settlement file list and real-time settlement file access address to complete the update of the global state data.

[0115] The settlement files are real-time settlement files RS1-RSn, RS1 represents the real-time settlement file of the first settlement, and RSn represents the real-time settlement file of the nth settlement.

[0116] Among them, the real-time settlement status includes: real-time settlement and non-real-time settlement; the real-time settlement file list contains all relevant files for real-time processing and settlement, and the type and content of these files depend on specific business needs and operating environment; the real-time settlement file access address is usually a network link, through which you can directly access and download real-time settlement files, which may contain detailed information about the transaction, such as transaction amount or transaction time.

[0117] Among them, the corresponding real-time settlement node in the blockchain needs to rely on specific business processing specifications to ensure the accuracy and consistency of the data, based on the status of the real-time settlement, the list of real-time settlement files, and the access address of the real-time settlement files.

[0118] Among them, some access addresses are protected. Due to security and privacy considerations, only those with corresponding permissions can access them.

[0119] In one example of the present application, the settlement system is a real-time settlement system; accordingly, in step S204, any settlement system determines whether the current version of the billing data is the latest version. If it is determined that the current version of the billing data is not the latest version, it requests the latest version of the billing data from the financial system.

[0120] In another example of the present application, the settlement system is a quasi-real-time settlement system; the corresponding settlement node in the blockchain is a quasi-real-time settlement node; the settlement information corresponding to the settlement file includes: quasi-real-time settlement status, quasi-real-time settlement file list, and quasi-real-time settlement file access address. Accordingly, step S206 specifically includes: the corresponding quasi-real-time settlement node in the blockchain writes back the quasi-real-time settlement field in the global state data according to the quasi-real-time settlement status, quasi-real-time settlement file list, and quasi-real-time settlement file access address to complete the update of the global state data.

[0121] The settlement files are quasi-real-time settlement files DS1-DSn, DS1 represents the quasi-real-time settlement file of the first settlement, and DSn represents the quasi-real-time settlement file of the nth settlement.

[0122] Among them, the quasi-real-time settlement status includes: quasi-real-time settlement and non-quasi-real-time settlement; the quasi-real-time settlement file list includes all relevant files for quasi-real-time processing and settlement; the quasi-real-time settlement file access address is usually a network link, through which the quasi-real-time settlement file can be directly accessed and downloaded.

[0123] In one example of the present application, the settlement system is a quasi-real-time settlement system; accordingly, in step S204, any settlement system determines whether the current version of the bill data is the latest version. If it is determined that the current version of the bill data is not the latest version, it requests the latest version of the bill data from the financial system or requests settlement information from the real-time settlement system.

[0124] In another example of the present application, the settlement system is a statistical settlement system; the corresponding settlement node in the blockchain is a statistical settlement node; the settlement information corresponding to the settlement file includes: statistical settlement status, statistical settlement file list, and statistical settlement file access address. Accordingly, step S206 specifically includes: the corresponding statistical settlement node in the blockchain writes back the statistical settlement field in the global state data according to the statistical settlement status, statistical settlement file list, and statistical settlement file access address to complete the update of the global state data.

[0125] Among them, the settlement files are statistical settlement files SS1-SSn, SS1 represents the statistical settlement file of the first settlement, and SSn represents the statistical settlement file of the nth settlement.

[0126] The statistical settlement status includes: statistical real-time settlement and non-statistical real-time settlement; the statistical real-time settlement file list includes all relevant files for statistical real-time processing and settlement; the statistical real-time settlement file access address is usually a network link, through which the statistical real-time settlement file can be directly accessed and downloaded.

[0127] In one example of the present application, the settlement system is a statistical real-time settlement system; accordingly, in step S204, any settlement system, after determining whether the current version of the bill data is the latest version, if it is determined that the current version of the bill data is not the latest version, requests the latest version of the bill data from the financial system, requests settlement information from the real-time settlement system, or requests settlement information from the quasi-real-time settlement system.

[0128] In summary, in this embodiment, when any settlement system is a real-time settlement system, a quasi-real-time settlement system, and a statistical settlement system, an accurate update process of the global status data is realized between the corresponding settlement information and the corresponding settlement nodes in the blockchain, thereby ensuring a high degree of consistency in the settlement dimensions and calibers in the case of many-to-many settlement scenarios and billing data.

[0129] In one example of the present application, based on Figure 1 As shown in the application scenario diagram, this application focuses on describing how to settle bill data when applied to blockchain. The method includes:

[0130] S301: Receive any version of bill data sent by the financial system through the financial node of the blockchain, where the blockchain includes multiple nodes and the financial node is one of the multiple nodes.

[0131] S302: The financial node of the blockchain updates the global status data according to the bill data, and broadcasts the updated global status data in all nodes of the blockchain to complete synchronization.

[0132] Among them, the bill data is obtained through the financial node of the blockchain, and the bill field information in the global status data is updated, wherein the updated content in the global status data is all field information in the bill field information except the status identifier.

[0133] S303: Send the global status data corresponding to the current version of the bill data to any settlement system through the corresponding settlement node in the blockchain, where the settlement node is one of multiple nodes, so that any settlement system can determine whether the current version of the bill data is the latest version; if it is determined that the current version of the bill data is the latest version, then any settlement system starts the settlement procedure according to its own settlement rules to obtain the settlement file; verify whether the hash value of the bill attribute field in the current version of the bill data is consistent with the hash value of the bill attribute field in the bill data used by the settlement system for settlement processing.

[0134] Among them, through the corresponding settlement node in the blockchain, a request for global status data sent by any settlement system is received; and the global status data corresponding to the current version of the bill data is sent to any settlement system.

[0135] S304: Receive settlement information corresponding to the settlement file sent by any settlement system through the corresponding settlement node in the blockchain when determining that the hash value of the bill attribute field in the current version of the bill data is consistent with the hash value of the bill attribute field in the bill data used by the settlement system during settlement processing.

[0136] S305: Through the settlement node corresponding to the blockchain, the global status data is updated according to the settlement information corresponding to the received settlement file, and the updated global status data is broadcast in all nodes of the blockchain to complete synchronization.

[0137] Among them, the settlement system is a real-time settlement system; the corresponding settlement node in the blockchain is a real-time settlement node; the settlement information includes: real-time settlement status, real-time settlement file list and real-time settlement file access address; accordingly, through the corresponding settlement node in the blockchain, the real-time settlement information corresponding to the real-time settlement file is received; updating the global status data includes: the corresponding real-time settlement node in the blockchain writes back the real-time settlement field in the global status data according to the real-time settlement status, real-time settlement file list and real-time settlement file access address to complete the update of the global status data.

[0138] Among them, the settlement system is a quasi-real-time settlement system; the corresponding settlement node in the blockchain is a quasi-real-time settlement node; the settlement information includes: quasi-real-time settlement status, quasi-real-time settlement file list and quasi-real-time settlement file access address; accordingly, through the corresponding settlement node in the blockchain, the quasi-real-time settlement information corresponding to the quasi-real-time settlement file is received; updating the global status data includes: the corresponding quasi-real-time settlement node in the blockchain writes back the quasi-real-time settlement field in the global status data according to the quasi-real-time settlement status, the quasi-real-time settlement file list and the quasi-real-time settlement file access address to complete the update of the global status data.

[0139] Among them, the settlement system is a statistical settlement system; the corresponding settlement node in the blockchain is a statistical settlement node; the settlement information includes: statistical settlement status, statistical settlement file list and statistical settlement file access address; accordingly, through the corresponding settlement node in the blockchain, the statistical settlement information corresponding to the statistical settlement file is received; updating the global status data includes: the corresponding statistical settlement node in the blockchain writes back the statistical settlement field in the global status data according to the statistical settlement status, statistical settlement file list and statistical settlement file access address to complete the update of the global status data.

[0140] In summary, first, any settlement system is used to determine whether the current version of the bill data is the latest version; then, any settlement system is used to verify whether the hash value of the bill attribute field in the current version of the bill data is consistent with the hash value of the bill attribute field in the bill data used by the settlement system for settlement processing. The global status data corresponding to the bill data is verified twice, which strictly ensures the high consistency of settlement dimensions and calibers in settlement scenarios and many-to-many bill data, and avoids the situation where the same bill data version has inconsistent settlement results in different settlement scenarios.
