[0013] In order to make one or more embodiments of the present specification or the prior art clearer, the drawings needed in the embodiment or prior art description will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present specification, and other drawings can be obtained by those skilled in the art without creative labor.

[0014] An embodiment of a blockchain-based data processing method provided by the present specification:

[0015] Referring to Figure 1 , a blockchain-based data processing method processing flowchart provided by the present embodiment is shown, referring to Figure 2 , a blockchain-based data processing method processing flowchart applied to an institutional reimbursement scenario provided by the present embodiment is shown.

[0016] Referring to Figure 1 , the blockchain-based data processing method provided by the present embodiment is applied to a blockchain node in a blockchain, and the blockchain is used to store payment records and electronic tickets obtained by an institutional member based on an institutional reimbursement code after payment; the method specifically includes steps S102 to S108.

[0017] Step S102, after the reimbursement condition of the organization member is triggered, querying the payment record and electronic bill of the reimbursement payment event of the organization member in the blockchain.

[0018] The data processing method based on the blockchain provided in the embodiment takes the blockchain as the core, obtains the payment record and the electronic bill obtained after the reimbursement code is used for payment by the blockchain data storage, combines the reimbursement payment event of the organization member, and performs the reimbursement of the obtained combined to-be-reimbursed data, generates the reimbursement single of the organization member, and finally performs the accounting processing of the organization from the reimbursement single, thereby obtaining the accounting voucher for the tax reimbursement processing, avoiding the trust problem between the organization and the organization staff due to the account reconciliation, improving the trust degree between the organization and the organization staff, and avoiding the tampering of the organization account, and improving the credibility of the organization accounting.

[0019] The organization in the embodiment includes enterprises, institutions, social groups, enterprises and various forms of organizations, in addition, the organization not only includes the current organization, but also includes the internal organization of the organization, such as the department or branch of the enterprise. The organization member includes the organization staff and related personnel.

[0020] The reimbursement code is an organization code set by the organization for the payment, billing and reimbursement of the organization member. The organization code can uniquely identify the organization. The existence form of the organization code can be a two-dimensional code, a bar code, a sound code and the like. The reimbursement code can realize the integrated processing of payment, billing and reimbursement. In addition, the reimbursement code can also be used to identify the membership of the organization member in the organization, such as using the reimbursement code as a digital badge of the enterprise employee. The enterprise employee can receive the welfare and subsidies issued by the enterprise with the reimbursement code as the voucher.

[0021] The reimbursement condition is a trigger condition for triggering the reimbursement of the reimbursement payment record or behavior of the organization member. The reimbursement condition of the organization member includes at least one of the following: the reimbursement quota allocated by the organization to the organization member for the reimbursement code is used up, and the bill application control of the reimbursement payment event of the organization member is triggered; wherein the bill application control is configured on the payment completion page generated after the payment of the reimbursement payment event is completed.

[0022] In this embodiment, the blockchain is also used to store the organization's identifier and the association between the organization and its members. Specifically, before storing the payment records and electronic invoices of the organization's members on the blockchain, the organization's identifier and the association between the organization and its members are stored on the blockchain. Specifically, during the on-chain storage process, when the reimbursement code activation application of the organization is detected and the reimbursement code is successfully generated, the organization's identifier and the member identifiers of the organization's members are obtained; the association between the organization identifier and the member identifier is established, and the organization identifier and the association are uploaded to the blockchain.

[0023] In one optional implementation of this embodiment, during the process of activating the reimbursement code for the organization, the system checks whether the organization is a certified organization or whether the member submitting the reimbursement code activation request is the owner of the organization (e.g., a business owner). If yes, the system generates the reimbursement code and issues it to the organization or the member submitting the reimbursement code activation request, and establishes a binding relationship between the organization and the submitting organization account so that the organization member can deduct the reimbursement from the organization account during the reimbursement process. If no, it indicates that the organization does not meet the conditions for reimbursement code activation, and no action is taken, or a reminder message indicating that the reimbursement code activation failed is sent to the organization.

[0024] Based on the reimbursement code issued by the organization, the organization can proactively invite its members to grant them access to the reimbursement code. This allows members to use the reimbursement code for payments, invoicing, and reimbursement in scenarios such as business travel, official trips, hospitality, team building activities, office procurement, and welfare / subsidy distribution. The process of the organization proactively inviting members to grant access to the reimbursement code specifically includes: sending an activation invitation to the member to be authorized based on their activation request; verifying the member's identity upon detecting a confirmation instruction submitted by the member in response to the activation invitation; and establishing a mapping relationship between the member's and the organization's keyword information if the verification is successful, and uploading this mapping relationship to the blockchain. The organization's keyword information includes the organization's header information.

[0025] After granting access to the reimbursement code to its members, the organization can access the code through a third-party application's reimbursement code service. For example, employees who have been granted reimbursement code access can access the organization's reimbursement code through the reimbursement code service of a payment application installed on their own devices. The reimbursement payment event refers to an event triggered during the process of an organization member using the organization's reimbursement code for payment.

[0026] In a specific implementation, the premise of querying the payment record and the electronic bill from the blockchain is that the payment record and the electronic bill are stored in the blockchain in advance. Therefore, the payment record and the electronic bill need to be generated and stored in the blockchain before querying the payment record and the electronic bill. Specifically, the generation and storage of the payment record of the reimbursement payment event specifically include: performing fee control verification on the reimbursement payment event of the organization member according to the fee control rule configured by the reimbursement code; if the fee control verification passes, performing payment processing based on the organization account bound by the organization, obtaining the payment record of the reimbursement payment event, and uploading the payment record to the blockchain.

[0027] In addition, in the case where the fee control verification does not pass, in order to ensure that the processing of the reimbursement payment event of the organization member is not interrupted, the organization member is issued with reminder information of a reimbursement failure, the funds are transferred out from the member account of the organization member, and the transferred funds are transferred into the account of the merchant.

[0028] Optionally, the fee control verification is implemented in the following manner: determining a target reimbursement category to which the reimbursement payment event matches in at least one reimbursement category of the fee control rule; verifying whether the element information carried by the reimbursement payment event is within a value interval of a fee control element associated with the target reimbursement category;

[0029] If yes, it is determined that the reimbursement payment event passes the verification of the target reimbursement category, that is, the verification result of the fee control verification on the reimbursement payment event is that the verification passes;

[0030] If no, it is determined that the reimbursement payment event does not pass the verification of the target reimbursement category, that is, the verification result of the fee control verification on the reimbursement payment event is that the verification does not pass.

[0031] The fee control rule is used to verify whether an order submitted by an organization member meets the reimbursement conditions set by the organization. For example, the enterprise code of an enterprise can be used for payment by enterprise employees in scenarios such as business travel, business travel, entertainment, team building, office procurement, and welfare / subsidy distribution. The fee generated by the payment that meets the reimbursement conditions set by the enterprise is borne by the enterprise, thereby realizing automatic reimbursement or employee discount. Optionally, the fee control rule is configured with at least one reimbursement category of the reimbursement code, and the reimbursement category is associated with at least one fee control element. The fee control element includes at least one of the following: a time element, a subject compliance element, an amount element, and a location element. The reimbursement category includes but is not limited to business travel, business travel, entertainment, team building, office procurement, and welfare / subsidy distribution.

[0032] The time element is used to verify whether the consumption time of the member of the institution applying for reimbursement meets the institution's provisions; the subject compliance element is used to verify whether the consumption object of the member of the institution applying for reimbursement meets the institution's provisions, such as the enterprise stipulating that the expenses generated by riding a company bus or a specific public transportation vehicle can be reimbursed, and if the vehicle ridden by the enterprise employee does not meet the provisions, it cannot be reimbursed; the quota element is used to verify whether the amount of the member of the institution applying for reimbursement meets the institution's provisions; and the location element is used to verify whether the geographic location information of the place where the consumption of the member of the institution applying for reimbursement meets the institution's provisions.

[0033] It should be noted that the present embodiment is to improve the enthusiasm of the institution for using the reimbursement code service from the institution side, and the present embodiment introduces a financial institution in the reimbursement code service, and the institution opens a financial account in the financial institution as the actual fund payout party for paying the target order of the member of the institution, and then the institution makes a repayment to the financial institution according to the corresponding account period. In an optional implementation manner provided by the present embodiment, the institution account includes a financial account opened by the institution in the financial institution, such as a fund account, a credit account, or an account period account settled in an account period settlement manner; accordingly, the payment processing based on the institution account bound by the institution includes: transferring funds out of the financial account according to the order amount carried by the reimbursement payment event, and transferring the transferred funds into the account of the merchant; wherein the funds transferred out of the financial account are paid by the financial institution, and the institution repays the paid funds to the financial institution according to the agreed account period.

[0034] Specifically, in the process of issuing the electronic ticket, the ticket issuing institution can issue the electronic ticket in the ticket node of the blockchain, or the reimbursement processing system can issue the electronic ticket. In an optional implementation manner provided by the present embodiment, the electronic ticket is generated and uploaded by the ticket node of the ticket issuing institution in the blockchain, and the ticket node issues the electronic ticket in the following manner: querying the institution keyword information having a mapping relationship with the member of the institution in the blockchain; according to the institution keyword information and the payment record of the reimbursement payment event read from the blockchain, the electronic ticket of the reimbursement payment event is issued and chained.

[0035] In another optional implementation provided by the embodiment, the electronic receipt is uploaded by a reimbursement processing system accessing the blockchain node, and the reimbursement processing system obtains the electronic receipt in the following manner: performing fee control verification on the reimbursement payment event of the institutional member according to the fee control rule configured based on the reimbursement code; if the fee control verification is passed, performing payment processing based on the institutional account bound by the institution to obtain a payment record of the reimbursement payment event; obtaining the electronic receipt submitted by the institutional member, or transmitting the payment record to a receipt application link opened by the merchant to generate the electronic receipt of the reimbursement payment event.

[0036] In step S104, the association processing of the reimbursement payment event is performed based on the queried payment record and electronic receipt to obtain to-be-canceled data.

[0037] In actual application, in many scenarios, there are cases of combined reimbursement of multiple reimbursement payment events. For example, in the scenario of business travel of an institutional member, all reimbursement payment events of the institutional member in a business travel trip can be combined for reimbursement, or multiple consumption reimbursement payment events of the institutional member in a business travel trip can be combined for reimbursement, or multiple dining reimbursement payment events can be combined for reimbursement. To improve the efficiency of reimbursement processing, in an optional implementation provided by the embodiment, the association processing is performed on the reimbursement payment event, and the following manner is used to implement the association processing:

[0038] According to the element information contained in the payment records of the multiple reimbursement payment events, the business payment relationship between the multiple reimbursement payment events is analyzed.

[0039] The multiple reimbursement payment events are combined into a business payment event based on the business payment relationship, and a payment record set and an electronic receipt set of the business payment event are determined as the to-be-canceled data.

[0040] In step S106, the to-be-canceled data is canceled, and a reimbursement single of the institutional member is generated and processed in a chain.

[0041] After the payment record and the electronic receipt of the institutional member queried in the blockchain are associated according to the reimbursement payment event to obtain the combined to-be-canceled data, in this step, the to-be-canceled data is canceled to generate the reimbursement single of the institutional member, which prepares data for subsequent accounting processing according to the reimbursement single, that is, data is prepared for subsequent steps of listing the corresponding items of the reimbursement single in the institutional expenses according to the reimbursement single of the institutional member.

[0042] In step S108, the accounting processing is performed according to the reimbursement single, and the obtained accounting voucher is uploaded to the blockchain for tax declaration processing.

[0043] In actual implementation, the tax declaration processing can be performed by a tax node of the tax authority in the blockchain, or by an agency system or a third-party system (such as a third-party tax platform or a financial management platform) accessing the node of the blockchain.

[0044] If the tax declaration processing is performed by a tax node of the tax authority in the blockchain, the tax declaration processing performed by the tax node specifically includes: reading the accounting voucher of the agency from the blockchain, and creating a declaration form of the agency based on the accounting voucher; performing the tax declaration processing of the agency based on the declaration form, and uploading the tax declaration processing result to the blockchain; and the agency accessing the tax declaration processing result through the node of the blockchain or an agency node of the agency in the blockchain.

[0045] If the tax declaration processing is performed by an agency system or a third-party system accessing the node of the blockchain, the agency system or the third-party system performs the tax declaration processing in the following manner: reading the accounting voucher of the agency from the blockchain, and creating a declaration form of the agency based on the accounting voucher; uploading the declaration form to the blockchain, so as to transmit the declaration form to the tax authority through the blockchain; or inputting the declaration form through a data interface provided by the tax authority, and uploading the tax declaration processing result returned by the data interface to the blockchain.

[0046] The following further describes the blockchain-based data processing method provided in this embodiment by taking an application of the blockchain-based data processing method provided in this embodiment in an agency reimbursement scenario, referring to Figure 2 The blockchain-based data processing method applied in the agency reimbursement scenario specifically includes steps S202 to S218.

[0047] In step S202, in a case where an agency reimbursement code opening application of an agency is detected and a reimbursement code is successfully generated, an association relationship between an agency identifier of the agency and a member identifier of an agency member is established, and the agency identifier and the association relationship are stored on a chain.

[0048] In step S204, a fee control verification is performed on a reimbursement payment event of the agency member according to a fee control rule configured by the reimbursement code.

[0049] In step S206, if the fee control verification is passed, a payment processing is performed based on an agency account bound by the agency, a payment record of the reimbursement payment event is obtained, and the payment record is stored on a chain.

[0050] In step S208, an electronic invoice of the reimbursement payment event is issued and processed on a chain according to the agency keyword information and the payment record of the reimbursement payment event read from the blockchain.

[0051] The organization keyword information has a mapping relationship with the organization member, and the organization keyword information is also stored on the chain based on the blockchain.

[0052] Step S210, after the reimbursement condition of the organization member is triggered, querying the payment record and electronic bill of the reimbursement payment event of the organization member in the blockchain.

[0053] Step S212, based on the queried payment record and electronic bill, the association processing of the reimbursement payment event is performed to obtain the to-be-reimbursed data.

[0054] Step S214, the to-be-reimbursed data is processed for reimbursement, and the reimbursement single of the organization member is generated and processed for on-chain.

[0055] Step S216, according to the reimbursement single, the accounting processing is performed, and the obtained accounting voucher is uploaded to the blockchain.

[0056] Step S218, the tax node in the blockchain creates the declaration table of the organization according to the on-chain stored accounting voucher, and performs the tax declaration processing according to the declaration table, and uploads the tax declaration processing result to the blockchain.

[0075] The storage medium provided in the specification is implemented as follows:

[0076] According to the above description, a blockchain-based data processing method is provided, and based on the same technical concept, one or more embodiments of the specification also provide a storage medium.

[0078] After the verification condition of the institution member is triggered, the payment record and electronic receipt of the reimbursement payment event of the institution member are queried in the blockchain; the blockchain is used to record the payment record and electronic receipt obtained after the institution member makes payment based on the reimbursement code of the institution;

[0083] The above describes particular embodiments of the present specification. Other embodiments are within the scope of the appended claims. In some cases, the acts or steps recited in the claims can be performed in a different order than the order in which they are recited and still achieve desirable results. In addition, the processes depicted in the figures do not necessarily require the particular order shown, or sequential order, to achieve the desired results. In certain implementations, multitasking and parallel processing can be advantageous or necessary.

[0084] In the 1930s, it was clear to distinguish whether an improvement in a technology was in hardware (e.g., improvement in circuit structure of diodes, transistors, switches, etc.) or in software (e.g., improvement in method flow). However, as technology has evolved, many improvements in method flow today can be considered as direct improvements in hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented by a hardware entity module. For example, a programmable logic device (PLD) (e.g., a field programmable gate array (FPGA)) is an integrated circuit whose logic function is determined by user programming of the device. A digital system is "integrated" on a PLD by the designer programming it, rather than by asking a chip manufacturer to design and fabricate a custom integrated circuit chip. Moreover, instead of manually fabricating an integrated circuit chip, this programming is now mostly implemented by "logic compiler" software, which is similar to software compilers used in program development, and the original code to be compiled is written in a specific programming language, called a hardware description language (HDL), of which there are many, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., the most commonly used being VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should be clear to those skilled in the art that, by simply logically programming a method flow in one of the above hardware description languages and programming it into an integrated circuit, a hardware circuit implementing the logical method flow can be easily obtained.

[0085] The controller can be implemented in any suitable way, e.g. the controller can take the form of a microprocessor or processor and a computer readable medium storing computer readable program code, e.g. software or firmware, executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller and an embedded microcontroller, examples of controllers include but are not limited to the following microcontrollers: ARC 625D, Atmel AT91 SAM, Microchip PIC18F26K20 and Silicone Labs C8051F320, the memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also know that in addition to being implemented in pure computer readable program code form, the controller can perfectly well be implemented by means of logic programmed into logic gates, switches, application specific integrated circuits, programmable logic controllers and embedded microcontrollers, etc. to perform the same functions. The controller can thus be considered a hardware component, and the means comprised therein for performing various functions can be considered structures within the hardware component. Alternatively, or even additionally, the means for performing various functions can be considered both software modules implementing the method and structures within the hardware component.

[0086] The systems, apparatuses, modules or units illustrated by the above embodiments can be specifically implemented by computer chips or entities, or by products with certain functions. A typical implementation device is a computer. Specifically, the computer can be, for example, a personal computer, a laptop computer, a cellular phone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

[0087] For the sake of description, the above apparatuses are described in functional division and are described respectively. Of course, the functions of the units can be implemented in the same or multiple software and / or hardware when implementing the embodiments of the present specification.

Therefore, one or more embodiments of the present specification can take the form of a complete hardware embodiment, a complete software embodiment, or an embodiment combining software and hardware aspects.
