[0079] First, the concepts involved in the embodiments of the present application are described:

[0080] (1) Blockchain: Blockchain is a new application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, and encryption algorithm. Blockchain is essentially a decentralized database, a string of data blocks generated using cryptographic methods. Each data block contains information about a batch of network transactions, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block. Blockchain can include the blockchain underlying platform, the platform product service layer, and the application service layer.

[0081] Blockchains are generally divided into three types: public blockchain, private blockchain, and consortium blockchain.

[0082] Public chains are the most decentralized. A common example is Ethereum. Nodes and participants joining a public chain can access data, publish transactions, and compete for the right to record new blocks. Furthermore, each node and participant can freely join and exit the public chain. Private chains, on the other hand, are controlled by a specific organization or institution. Data access is also controlled by that organization or institution. Participants are limited and cannot join the chain at will, requiring approval from the organization or institution.

[0083] A consortium blockchain, also known as a community blockchain, is a blockchain whose consensus process is controlled by preselected nodes. It's a hybrid of public and private blockchains, achieving "partial decentralization." Each node on the chain typically has a corresponding entity or organization. Participants join the network through authorization and form a stakeholder alliance to jointly maintain the blockchain's operations. Consortium chains allow new participants to join an established blockchain and share data, rather than building it from scratch. Furthermore, by jointly solving common problems, companies can reduce development costs and time.

[0084] Whether it's a public, private, or consortium blockchain, they all offer smart contract functionality. Smart contracts on the blockchain are contracts that can be triggered and executed by transactions on the blockchain system. Smart contracts can be defined in code.

[0085] (2) A shared ledger is used to provide functions such as storage and query of data fingerprints, and to send the recorded data of operations on files or devices (also referred to as logs or benchmark data in this application) to other nodes in the blockchain network. After other nodes verify that the data is valid, they store the recorded data in a temporary block and can also send confirmation to the node that initiated the operation.

[0086] (3) Smart contracts are computerized protocols that can execute the terms of a contract. They are implemented by deploying code on a shared ledger that is executed when certain conditions are met. The code is used to complete automated transactions based on actual business needs. Smart contracts are not limited to executing contracts for transactions, but can also execute contracts that process received information.

[0087] (4) Public key, private key, and transaction address

[0088] Nodes participating in a blockchain network possess a pair of public and private keys, which can be created using an asymmetric encryption algorithm. For example, a node can first randomly generate a private key. Then, based on the principles of an asymmetric encryption algorithm, the public key is calculated from the private key. The public key is then subjected to a series of digital signature operations to obtain the transaction address (also known as the wallet address). In other words, knowing a node's public key can calculate its transaction address. In some embodiments, the public key can also serve as a wallet address or an identifier for a wallet address.

[0089] Asymmetric encryption algorithms include, but are not limited to, the Elgamal algorithm, the Rabin algorithm, the Diffie-Hellman algorithm, and the Elliptic Curve Cryptography (ECC) algorithm. Key pairs consist of public and private keys; the public key is typically broadcast to the blockchain network, while the private key is maintained by the nodes. It should be noted that public and private keys are unique within the blockchain network.

[0090] (5) Collection and payment on behalf of others

[0091] Entrusted tax collection, also known as "agent collection" or "agent payment," refers to a tax collection method whereby the tax authorities entrust local township or village governments, villagers' organizations, or other entities to collect taxes in accordance with the law and submit them to the tax authorities on a regular basis in areas where tax sources are scattered and difficult to assign dedicated personnel to manage. Entrusted tax collection requires written authorization procedures that clearly specify the types of taxes, tax items, applicable tax rates, payment methods, and payment deadlines for the entrusted collection, as well as responsibilities. The relevant certificates, labels, and necessary collection vouchers are issued, and a handling fee is paid as required. The local township or village government, villagers' organization, or other entity entrusted by the tax authorities is called the "tax collector," and the person for whom the tax collector is responsible for collecting taxes is called the "person being collected."

[0092] For example, since the internet anchor working on Company A’s online platform has not signed an employment contract with the company, if the company collects taxes on behalf of the internet anchor, Company A is the tax collector and the internet anchor is the taxee.

[0093] For example, since the manager working at Company B has not signed an employment contract with the company, if the company collects taxes on behalf of the manager, Company B is the tax collector and the agent is the taxee.

[0094] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0095] In the traditional entrusted collection system, the specific process is generally that the collector applies for the entrusted collection qualification from the tax bureau to which he belongs, and then goes to the tax bureau to obtain the relevant paper receipts to complete the collection process, that is, collect the relevant taxes from the persons being collected in accordance with the regulations and fill out the tax collection and payment slip, etc. Finally, at the end of the month, the data of taxes collected by the collector from all persons being collected are summarized, all taxes are paid to the tax bureau and deposited into the warehouse, and the completion procedures are completed with the tax bureau.

[0096] However, the above-mentioned method of entrusting tax collection has the following problems: 1. The process of entrusting tax collection is all offline operations, and many paper documents and receipts are required. For example, when the collector completes the collection, the person being collected needs to fill out a paper tax payment slip; 2. It is difficult for the tax bureau to supervise the process of entrusting tax collection. For example, if the "collector" tamper with the time or amount of tax collection, it is difficult for the tax bureau to detect; 3. Since it is difficult for the tax bureau to supervise the process of entrusting tax collection, the tax bureau does not allow the collector to issue invoices for the person being collected. However, often because the person being collected does not have the qualifications to issue invoices, the collector has the problem of not having invoices for accounting.

[0097] To address the above issues, embodiments of the present invention provide a blockchain-based tax payment receipt solution. In this solution, tax agents can delegate tax collection through the blockchain, achieving a paperless office environment. Data collected during the delegation process can be transmitted to the blockchain. Because data on the blockchain remains unmodified, the tax bureau can effectively monitor the delegation process.

[0098] like Figure 1 As shown, an embodiment of the present invention provides a data processing system, which may include a tax agent device 101, a first tax bureau device 102, a second tax bureau device 103, a device of the taxee 104, a third-party server 105, and a blockchain network 106.

[0099] The blockchain network 106 may include multiple nodes 1061. The tax agent device 101 and the first tax bureau device 102 are nodes in the blockchain network 106. The blockchain network 106 may be a private, public, or consortium blockchain. The tax agent device 101 is a device controlled by the tax agent; the first tax bureau device 102 and the second tax bureau device 103 may be one of the tax bureau devices (equipment of the tax bureau) in each region. In one scenario, the first tax bureau device 102 may be one of the tax bureau devices in each region, added to the blockchain network 106 as a node. The second tax bureau device 103 may be a computer device in communication with the first tax bureau device 102, such as a server or other computer device on the official website of the tax bureau in each region.

[0100] In some embodiments, blockchain network 106 may be a consortium chain, comprising at least one business node and at least one consensus node. Business nodes and consensus nodes have different permissions. Business nodes may possess one or more of the following functions: viewing, uploading, verifying, and storing transaction data. They require authorization from a consensus node or a tax bureau device (e.g., first tax bureau device 102 or second tax bureau device 103) to join the consortium chain. This may be a tax agent device 101. Consensus nodes possess functions such as viewing, uploading, verifying, and storing transaction data. They may be tax bureau devices, such as first tax bureau devices 101 in each region. Alternatively, business nodes in blockchain network 106, such as tax agent devices 101, may only possess functions of viewing and uploading transaction data.

[0101] To ensure information intercommunication within blockchain network 106, an information connection may exist between each node in blockchain network 106, and information can be transmitted between nodes via such information connection. For example, when any node in blockchain network 106 initially receives transaction data, it verifies the legitimacy of the transaction data. If the transaction data is legitimate, it may broadcast the transaction data to its neighboring nodes to facilitate receipt of the transaction data by other nodes in the blockchain network. It should be understood that after the node receives the same transaction data again, it will no longer broadcast it to neighboring nodes to avoid the unlimited propagation of the transaction data. In the embodiments of the present application, the transaction data may be the first transaction data, the second transaction data, etc.

[0102] After receiving the above transaction data, the nodes or consensus nodes in the blockchain network write the transaction data into the block according to the transaction data. After generating the block, the consensus node publishes the block to the blockchain network. The propagation method of the new block is similar to the propagation method of the transaction data, which will not be repeated here. The consensus node that receives the new block can detect the legitimacy of the block content and check whether the block is on the longest legal chain. Then, each consensus node can store the maximum legal chain to ensure the consistency of the data stored by each consensus node.

[0103] The third-party server 105 is a payment platform server used to complete the transfer of digital assets off-chain, for example, a WeChat server, a bank server, etc. Optionally, the tax payee device 104 can be a smart device such as a mobile phone or a computer, which is not limited here.

[0104] The tax collector's device 1011 can request a number segment from the first tax bureau device 102 or the second tax bureau device 103. For example, a first request is sent to the tax bureau device, where the first request is used to request the tax bureau's number segment for the tax collector. This number segment is used to identify the tax collector in the tax payment slip, i.e., to uniquely identify the tax collector in the tax payment slip. In some implementations, the identification code of the tax payment slip includes the tax collector's number segment, which can be located in a fixed position in the identification code of the tax payment slip, such as the first n digits, where n is the total number of digits in the number segment. Optionally, the first request can carry the tax collector's identifier. For example, if the tax collector is a company, the tax collector's identifier can be the company name.

[0105] The tax bureau device receives the first request, generates a number segment of the tax agent according to the first request, and sends the number segment of the tax agent to the tax agent device 101 .

[0106] The tax collector device 101 can obtain personal information about the first tax recipient, such as the tax recipient's name, ID number, bank account used for payment, and monthly / annual income. Furthermore, the tax collector device 101 can generate a first tax payment receipt based on the tax collector's number segment, the first tax recipient's income, and the tax rate. Furthermore, the tax collector device 101 can generate first transaction data based on the identification code and the tax amount of the first tax recipient in the first tax payment receipt, and upload the first transaction data to the blockchain network 106. The first tax payment receipt includes the identification code and the tax amount of the first tax recipient. The first transaction data indicates the transfer of a first digital asset from the tax collector's transaction address to the transaction address of the first tax bureau. The first transaction data includes the identification code of the first tax payment receipt, and the first digital asset indicates the tax amount of the first tax recipient in the first tax payment receipt. It should be understood that if taxes are paid monthly, a tax payment receipt can be generated for each tax recipient per month.

[0107] After the tax collector's device 101 generates a tax payment notice, it can send the tax payment notice to the device of the person being taxed. The device 104 of the person being taxed can query the payment status based on the identification code of the tax payment notice. For example, after the tax collector's device 101 generates the first tax payment notice, it can send the first tax payment notice to the device of the first person being taxed. The person being taxed can send a query request carrying the identification code of the first tax payment notice to the tax collector's device 101 or the tax bureau device. The tax collector's device 101 queries the transaction data of the first tax payment notice on the blockchain network 106, determines the payment status of the first tax payment notice based on the queried transaction data, and then sends the payment status of the first tax payment notice to the device of the first person being taxed.

[0108] The tax collector's device 101 can complete the payment of the tax payment notice through a third party (such as online banking, Alipay, WeChat, ePay, etc.), or pay the tax manually at the tax bureau counter, although this embodiment of the present application is not limited thereto. For example, the tax collector's device 101 sends a first transfer order to a third-party server 105 (such as an online banking, Alipay, WeChat, ePay, etc. server). The first transfer order includes the identification code of the first tax payment notice and instructs the transfer of a second digital asset from the tax collector's account to an account at the first tax bureau. The second digital asset represents the tax payment of the first tax payee. After receiving the first transfer order, the third-party server 105 transfers the second digital asset from the tax collector's account to the first tax bureau's account. It then sends the transfer result of the first transfer order to the first tax bureau device 102 or the second tax bureau device 103. The transfer result includes the identification code of the first tax payment notice and an indication of successful transfer. The third-party server 105 may also send the transfer result of the first transfer order to the tax agent device 101 , and then the tax agent device 101 sends the transfer result to the first tax bureau device 102 or the tax agent device 101 uploads the transfer result to the blockchain network 106 .

[0109] When the first tax bureau device 102 detects that the tax on the first tax payment slip has been paid, it can upload the second transaction data to the blockchain network 106. The second transaction data is used to indicate the transfer of the first digital asset from the transaction address of the first tax bureau to the transaction address of the tax agent.

[0110] It should be noted that the first tax bureau device 102 and the second tax bureau device 103 can be the same device or different devices. In the case where the first tax bureau device 102 and the second tax bureau device 103 are different devices, the first tax bureau device 102 can share data with the second tax bureau device 103, such as the payment status of the first tax payment receipt, transaction data of the first tax payment receipt, transfer results, etc.

[0111] It can be seen that the data processing scheme proposed in the embodiment of the present invention may have at least the following advantages: 1. Converting traditional offline processing into online processing, realizing convenient operation of the entrusted collection process, and realizing paperless processing; 2. Utilizing the openness and transparency of the blockchain network, the uploaded data is independent of the tax agent's equipment, which not only ensures the security and reliability of the data and is not easy to lose, but also limits the tax agent's equipment's control over the data and cannot modify the data at will; 3. In the process of entrusted collection, the transaction data is uploaded to the blockchain network, adding a query function to the traditional entrusted collection, and the person being collected can query the status of personal tax payment.

[0112] Based on the above description, an embodiment of the present invention proposes a data processing method, which can be executed by the data processing system mentioned above. The method includes some or all of the following processes / steps:

[0113] (1) Collecting number segments on behalf of tax payers

[0114] See also Figure 2 , Figure 2 This is a flow chart of a method for a tax payer to obtain a number segment according to an embodiment of the present application. The method for a tax payer to obtain a number segment may include:

[0115] S202: The tax agent device sends a first request to the second tax bureau device. The first request is used to apply to the second tax bureau for a number segment of a tax payment slip. The number segment is used to identify the tax agent in the tax payment slip.

[0116] The second tax bureau device and the first tax bureau device may be the same device or different devices. Optionally, the first request may also carry the identifier of the tax agent. For example, if the tax agent is an enterprise, the identifier of the tax agent may be the enterprise's name or taxpayer identification number.

[0117] This number segment is used to generate the identification code of the tax payment slip after being arranged and combined with other numbers according to certain rules. The identification code of a tax payment slip uniquely corresponds to a tax payment slip. The identification code of a tax payment slip is generally a row of numbers in the upper right corner of the tax payment slip.

[0118] S204: The second tax bureau device receives the first request and generates a number segment for the tax collector according to the first request.

[0119] After receiving the first request, the second tax bureau device can randomly generate N characters, which serve as the tax agent's number segment. These N characters do not conflict with the number segments of other tax agents. Therefore, the tax agent's number segment uniquely corresponds to one tax agent and serves as an identifier to distinguish different tax agents.

[0120] S206: The second tax bureau device sends the number segment of the tax agent to the tax agent device.

[0121] The second tax bureau device can send the tax payer's number segment to the tax payer's device via email or other methods. Since each number segment uniquely corresponds to a tax payer, the tax payer generates a tax payment receipt identification code based on the number segment, which is used to identify the tax payment receipt of the tax payer for the tax payer.

[0122] (2) The tax collector pays taxes on behalf of the tax recipient

[0123] See also Figure 3 , Figure 3 This is a flow chart of a data processing method provided in an embodiment of the present application. The method may include some or all of the following steps:

[0124] S302: The tax collector's device generates a first tax payment receipt according to the tax collector's number segment, the income of the first tax recipient, and the tax rate. The first tax payment receipt includes an identification code of the first tax payment receipt and the tax of the first tax recipient.

[0125] The first tax payment receipt may also include the identification of the first person being taxed.

[0126] See also Figure 4A , Figure 4A A schematic diagram of a tax payment slip provided in an embodiment of the present application. In this embodiment, the tax payee is also known as the taxpayer, the tax authority is also known as the taxpayer, and the tax agent is also known as the tax collection agency. The identification code of the first tax payment slip is the serial number in the upper right corner of the tax payment slip. The tax payment slip includes: taxpayer name, tax rate, tax authority, tax collection agency, and serial number. The identification code of the first tax payment slip includes the tax agent's number segment, which is used to indicate the information of the first tax payee. For example, each tax payee has a unique corresponding tax payment slip each month, and each tax payment slip has a unique identification code.

[0127] It should be noted that it is not limited to Figure 4A The schematic diagram of the tax payment slip provided can also be designed into other tax payment slip styles according to functional requirements.

[0128] S304: The tax agent's device uploads the first transaction data to the blockchain network. The first transaction data is used to transfer the first digital asset from the tax agent's transaction address to the transaction address of the first tax bureau. The first transaction data includes the identification code of the first tax payment receipt. The first digital asset is used to indicate the tax of the first tax recipient in the first tax payment receipt.

[0129] Based on the first tax payment receipt, the tax agent's device can generate first transaction data. The first transaction data includes at least the identification code of the first tax payment receipt and data indicating the transfer of the first digital asset from the tax agent's transaction address to the transaction address of the first tax bureau. The tax agent's device signs the first transaction data using the tax agent's private key and uploads the signed first transaction data to the blockchain network, causing the blockchain network to store the first transaction data. The tax agent's device then broadcasts the first transaction data to other nodes in the blockchain network, causing the blockchain network to store the first transaction data.

[0130] In one implementation, other nodes in the blockchain network receive the first transaction data, wherein the business node stores the first transaction data through a consensus algorithm, packages the first data into the latest block, and then broadcasts the latest block so that other nodes in the blockchain network receive the latest block and synchronize the block to the blockchain stored by the node.

[0131] S306: The tax collector pays the tax of the first tax collector to the first tax bureau according to the first tax payment notice.

[0132] A specific implementation method of the tax collection agent completing the payment of the tax on the first tax payment slip may include the following steps S3061-S3063:

[0133] The tax payer's device can complete the payment of the first tax payment slip through a third-party server. The third-party server is the payment platform's server, which is used to complete the transfer of digital assets off-chain, such as WeChat's server, bank's server, etc.

[0134] S3061: The collection agent's device sends a transfer order to the third-party server.

[0135] The transfer order includes the identification code of the first tax payment receipt, which is used to instruct the transfer of the second digital asset from the tax agent's account to the first tax bureau's account, and the second digital asset is used to indicate the tax payment of the first tax agent. For example, the account of the first tax bureau

[0136] S3062: The third-party server receives the transfer order and transfers the second digital asset from the tax agent's account to the first tax bureau's account according to the transfer order.

[0137] S3063: The third-party server sends the transfer result of the transfer order to the first tax bureau device. The transfer result includes the identification code of the first tax payment receipt and a transfer success indicator.

[0138] In one implementation of S3063, the third-party server sends the transfer result of the transfer order to the tax agent's device, and then the tax agent's device sends the transfer result to the first tax bureau's device.

[0139] In another implementation of S3063, the third-party server sends the transfer result of the transfer order to the collection agent device, and then the collection agent device uploads the transfer result to the blockchain network.

[0140] It should be noted that, the implementation method is not limited to the above, and step S306 may also include other implementation methods, such as the tax collector paying the fees offline at the tax bureau, etc., which will not be repeated here.

[0141] S308: The first tax bureau device detects whether the tax payment of the first tax payee has been completed based on the identification code of the first tax payment receipt.

[0142] In step S3063, the third-party server sends the transfer result of the transfer order to the first tax bureau device. The transfer result includes the identification code of the first tax payment order and the transfer success mark. Then, the tax payment of the first tax payment order is completed.

[0143] It should be noted that, the implementation method is not limited to the above, and step S308 may also include other implementation methods. For example, after the tax bureau staff receives the tax in the first tax payment notice, they input an instruction indicating that the payment has been completed into the tax bureau equipment, etc., which will not be repeated here.

[0144] S310: When the first tax bureau device detects that the tax on the first tax payment notice has been paid, the first tax bureau device uploads second transaction data to the blockchain network, where the second transaction data is used to indicate the transfer of the first digital asset from the transaction address of the first tax bureau to the transaction address of the tax agent.

[0145] The uploading of the first transaction data to the blockchain network can be described in the above-mentioned step S304 and will not be repeated here. The second transaction data may also include the identification code of the first tax payment receipt, the transfer order, and the transfer result of the transfer order, etc., which are not limited in this embodiment.

[0146] In this embodiment of the present invention, after the tax collector's device generates a first tax payment receipt based on the tax collector's number segment, the first tax recipient's income, and the tax rate, it uploads first transaction data to the blockchain network. This first transaction data indicates the transfer of a first digital asset from the tax collector's transaction address to the first tax bureau's transaction address. Subsequently, the tax collector's device pays the tax indicated in the first tax payment receipt to the first tax bureau. Upon detecting that the tax payment for the first tax recipient has been completed, the first tax bureau uploads second transaction data to the blockchain network. This second transaction data indicates the transfer of the first digital asset from the first tax bureau's transaction address to the tax collector's transaction address. It can be seen that, firstly, having the tax collector's device generate the first tax payment receipt reduces the need for offline transactions compared to traditional entrusted tax collection. Secondly, both the first and second transaction data are uploaded to the blockchain network, preventing the tax collector's device from arbitrarily modifying the data, thus ensuring data security and reliability.

[0147] In some embodiments, the tax bureau equipment can periodically update the transaction data on the blockchain to the tax bureau system. For example, the transaction data can be updated once every hour, and the person being taxed can check the payment status of the tax payment slip through the tax bureau system.

[0148] (3) The tax payee inquires about the payment status of the tax payment receipt

[0149] In an embodiment of the present invention, a method is provided for a tax payee to query the payment status of a tax payment receipt. Figure 4B As shown, after step S302, the method may include some or all of the following steps:

[0150] S402: After the tax collection agent device generates the tax payment receipt, it sends the first tax payment receipt to the first tax collection agent.

[0151] After the tax agent device generates the first tax payment receipt, it can send the first tax payment receipt to the first tax recipient via email, etc. The first tax payment receipt can be in electronic form or other forms, which are not limited in this embodiment.

[0152] S404: The device of the tax payee receives the first tax payment receipt and sends a query request to the tax bureau device. The query request includes the identification code of the first tax payment receipt.

[0153] Specifically, the tax bureau device can provide a query portal through the tax bureau system. The first tax payee can log in to the tax bureau system on the tax payee's device and enter a query request at the query portal. The query request can be the identification code of the first tax payment receipt, or the identification code of the first tax price receipt and the name of the first tax payee. The tax bureau device can be a node in the blockchain network, such as the first tax bureau device or the second tax bureau device, or it can be an off-chain tax bureau server. For example, the tax bureau server can interact with the first tax bureau device and regularly update and obtain the tax payee's transaction data from the first tax bureau device.

[0154] S406: The tax bureau device receives the query request and queries the transaction data of the first tax payment receipt in the blockchain network according to the identification code of the first tax payment receipt.

[0155] Specifically, when the tax bureau device regularly updates the transaction data of the blockchain to the tax bureau system, the tax bureau device can query the transaction status of the first tax payment slip in the tax bureau system based on the identification code of the first tax payment slip.

[0156] S408: The tax bureau device determines the payment status of the first tax payment receipt based on the queried transaction data.

[0157] Since transaction data on the blockchain network is uploaded by the tax agent's device using a private key signature, and the public key and private key correspond one-to-one, the transaction data uploaded with the private key signature can only be verified by the public key corresponding to the private key. Therefore, the tax bureau's device can obtain the transaction data uploaded and signed by the tax agent's private key on the blockchain network through the tax agent's public key.

[0158] When the tax bureau equipment queries the first transaction data in the blockchain network, it determines that the payment status of the first tax payment notice is "being processed". The payment status of the first tax payment notice may also include more detailed payment data, such as the tax of the first person being collected in the first tax payment notice and the time when the first transaction data was uploaded.

[0159] When the tax bureau equipment queries the second transaction data on the blockchain network, it determines that the payment status of the first tax payment slip is "processing completed". The payment status of the first tax payment slip may also include more detailed payment data, such as the transfer order, the transfer result of the transfer order, and the time when the second transaction data is uploaded.

[0160] S410: The tax bureau device sends the payment status of the first tax payment receipt to the device of the tax payee.

[0161] Specifically, the first tax payee logs into the tax bureau system on the tax payee's device, and the tax bureau system sends the payment status of the determined first tax payment notice to the tax payee's device, and the first tax payee can query the real-time payment status of the first tax payment notice.

[0162] It should be noted that the method for the tax collector to inquire about the payment status of the tax payment receipt is not limited to the above method, and may also include other implementation methods, which will not be repeated here.

[0163] In an embodiment of the present invention, the tax collector's device generates a first tax payment receipt based on the tax collector's number segment, the income of the first taxee, and the tax rate. The first tax payment receipt includes an identification code of the first tax payment receipt and the tax of the first taxee; the tax collector's device uploads first transaction data to the blockchain network. The first transaction data is used to indicate the transfer of the first digital asset from the tax collector's transaction address to the transaction address of the first tax bureau. The first transaction data includes the identification code of the first tax payment receipt. The first digital asset is used to indicate the tax of the first taxee in the first tax payment receipt; the tax collector's device pays the tax of the first taxee to the first tax bureau according to the first tax payment receipt, so that when the first tax bureau device detects that the tax of the first taxee has been paid, the first tax bureau device uploads second transaction data to the blockchain network. The second transaction data is used to indicate the transfer of the first digital asset from the transaction address of the first tax bureau to the transaction address of the tax collector. It can be seen that, firstly, the first tax payment receipt is generated by the tax collector's device, which reduces the offline business procedures compared to the traditional entrusted tax collection; secondly, the first transaction data and the second transaction data are both uploaded to the blockchain network, which restricts the tax collector's device from modifying the data at will, ensuring the security and reliability of the data.

[0164] Based on the description of the above method embodiment, the embodiment of the present invention further proposes a data processing device 500, which can be operated in the following manner: Figure 1 In the tax agent device 101 shown, the data processing device 500 may be the tax agent device 101 or a computer program (including program code) running in the tax agent device 101.

[0178] In an embodiment of the present invention, the tax collector's device generates a first tax payment receipt based on the tax collector's number segment, the income of the first taxee, and the tax rate. The first tax payment receipt includes an identification code of the first tax payment receipt and the tax of the first taxee; the tax collector's device uploads first transaction data to the blockchain network.
