It should be noted that FIG. 1 is only one example of a particular specific example and is intended to illustrate the types of components that may be present in a computing device as described above.

Fig. 2A is a schematic diagram of a block chain-based cross-border trade data management system 200 according to the present embodiment. Referring to fig. 2A, the cross-border trade data management system 200 is a blockchain system, including: a blockchain 201 and a plurality of blockchain nodes 202 a-202 n. Each blockchain node 202 a-202 n runs a blockchain 201, and the blockchain 201 stores cross-border trade data related to cross-border trade services. Illustratively, the plurality of blockchain nodes 202 a-202 n may be: tax-related business nodes 202a, insurance server nodes 202b, financial server nodes 202c, carrier nodes 202d, customs nodes 202e, warehousing nodes 202f, forwarders nodes 202g, forwarders nodes 202h, suppliers nodes 202i, import and export server nodes 202j, buyers nodes 202k, and other interested party nodes 202 n.

Fig. 2B is a schematic flow diagram illustrating the flow between related parties of various business segments of the cross-border trade. Referring to fig. 2B, a cross-border transaction is first completed by the supplier and buyer parties of the cross-border trade (step 1). Then, the supplier or the buyer entrusts the import and export service party to complete the import and export business of the transaction object after completing the transaction (steps 2 and 3). Wherein, the supplier, the buyer and the import and export service party all belong to the import and export trade enterprise.

Then, the import and export service party entrusts the forwarder to complete the logistics business related to the cross-border trade (step 4), and provides the financial service related to the cross-border trade through the bank and the insurance company (step 5 and step 6).

Then, after receiving the logistics business entrustment of the import and export service party, the goods forwarder entrusts the transportation business related to the cross-border trade to the corresponding transportation party, entrusts the warehousing business related to the cross-border trade to the corresponding warehousing party, entrusts the clearance service business related to the cross-border trade to the corresponding clearance party, and entrusts the delivery business related to the cross-border trade to the corresponding delivery party.

The customs authority then issues a supervision request (step 7), such as a customs request or the like, to a customs or other supervision authority over the course of the customs.

Of course, the above is merely an exemplary flow that describes various business segments of cross-border trading. In the actual cross-border trading process, changes can occur according to actual conditions. For example, a supplier or a buyer may interface directly with a forwarder, a bank, and an insurance company without going through an import-export service.

Further, the tax-related service party node 202a is a computing device of a tax-related service party, wherein the tax-related service party is, for example, but not limited to, a customs and a tax authority, and the tax-related service party node 202a is further connected with terminal devices of each system department of the tax-related service party, for example: the terminal device 100a is shown. The tax-related business party can handle tax-related business for the tax-related links of cross-border trade. Since the terminal device 100a of the tax-related service party can access the block chain 201 through the block chain node of the tax-related service party (i.e., the tax-related service party node 202a), the tax-related service party can read the cross-border trade data from the block chain 201 through the tax-related service party node 202a, then perform corresponding tax-related processing according to the read cross-border trade data, and write the tax-related result into the block chain 201. It should be noted that both the tax-related business side node 202a and the blockchain 201 in the system may be adapted to the above-described hardware architecture.

Under the operating environment, according to the first aspect of the present embodiment, there is provided a block chain-based cross-border trade tax-related information management method, which is applied to a computing device of a tax-related business party, where the computing device is a node of a block chain 201, and the block chain 201 is used for storing cross-border trade data of various business links related to cross-border transactions, where, referring to fig. 2A and fig. 2B, a business link includes at least one of the following: cross-border transactions, logistics services related to cross-border transactions, financial services related to cross-border transactions, and tax-related services related to cross-border transactions.

The method is implemented by the tax-involved business party node 202A shown in figure 2A. Fig. 3 shows a flow diagram of the method, which, with reference to fig. 3, comprises:

s302: receiving a tax-involved request related to cross-border trade, wherein the tax-involved request is used for requesting to transact tax-involved business related to the cross-border trade;

s304: reading cross-border trade data of cross-border trade from the blockchain in response to the tax-involved request;

s306: comparing the read cross-border trade data with cross-border trade data contained in the tax-involved request; and

s308: and processing the tax-related business under the condition that the cross-border trade data read from the blockchain is matched with the cross-border trade data contained in the tax-related request.

As described in the background section above, in cross-border trading, various business roles may be involved in tax-related businesses, such as: tax payment service, tax refund service, tax deduction and exemption declaration service, etc. In the process of handling tax-related services for each service role, customs and tax agencies need to acquire data information generated in each link in the whole cross-border trading process and perform corresponding auditing work. Only under the condition that the auditing result is accurate, the customs and the tax authority can process the corresponding tax-related business. However, today, the internet and informatization are developed, and at present, no company or one platform exists, and cross-border trade whole-flow chains can be integrated to form information synchronization. And various links in the cross-border trade process form 'information islands' of all roles, the IT system construction standard and scale are inconsistent, and the information data are unwilling to be shared with others due to the reason of business privacy. Therefore, when a tax-related business party (e.g., customs and tax agencies) processes a tax-related business related to a cross-border trade, data information related to the cross-border trade is difficult to obtain due to poor information communication among business links, so that the operating efficiency of the tax-related business party responsible for processing the tax-related business is low, and risks such as missed payment and wrong payment are high.

In view of the problems in the background art, as shown in fig. 2A and fig. 2B, in this embodiment, each service role in the cross-border trade may send a tax-related request related to the cross-border trade to the tax-related service node 202A of the tax-related service party when the tax-related requirement is met. For example: when the customs side needs to transact the tax-related service, the terminal device 100b of the customs side can send a corresponding tax-related request to the terminal device 100a of the tax-related service side, and the terminal device 100a forwards the tax-related request to the node 202a of the tax-related service side. At this point, the tax-involved business party node 202a receives a tax-involved request related to the cross-border trade.

Further, since the tax-related business node 202a is a node in the blockchain system 200, the tax-related business node 202a may read the cross-border trade data directly from the blockchain 201 in response to the tax-related request. For example, the cross-border trade data read from the blockchain 201 by the tax-related business side node 202a may be the cross-border trade data written into the blockchain 201 by the forwarder through the forwarder node 202 h. For example: the forwarder performs business interaction with the terminal device 100e of the customs through the terminal device 100h, so that the forwarder stores cross-border trade data generated in the interaction process with the customs to the blockchain 201 through the node 202h of the forwarder. Alternatively, the cross-border trade data read from blockchain 201 may be the cross-border trade data written to blockchain 201 by customs node 202 e. Alternatively, the cross-border trade data may also be cross-border trade data stored by other related parties.

Further, by using the characteristics of non-tamper property, accuracy, security, and the like of the data stored in the block chain 201, the tax-related service node 202a may use the cross-border trade data read from the block chain 201 as an audit basis, and compare the read cross-border trade data with the cross-border trade data included in the tax-related request. Finally, in the case that the cross-border trade data read from the blockchain 201 matches the cross-border trade data included in the tax-related request (i.e., in the case that the comparison result is consistent), the corresponding tax-related service is processed.

Thus, in this way, the tax-involved business side node 202a of the tax-involved business side first receives a tax-involved request related to the cross-border trade, then reads the cross-border trade data of the cross-border trade from the blockchain 201 in response to the tax-involved request, then compares the read cross-border trade data with the cross-border trade data included in the tax-involved request, and finally processes the tax-involved business in the case that the cross-border trade data read from the blockchain 201 matches the cross-border trade data included in the tax-involved request. Because the block link nodes corresponding to each business link can record cross-border trade data generated by the business link into the block link 201, and broadcast the newly generated blocks to each node of the block link system 200, and because the block link 201 has the characteristics of non-tamper property, decentralization, common recognition mechanism, encryption and the like, the whole cross-border trade flow chain can be integrated, and information synchronization and interconnection are realized. The tax-related business parties do not need to read cross-border trade data from each business link respectively and then conduct corresponding tax-related business handling, but directly read cross-border trade data generated in the cross-border trade process of each business link from the block chain 201 through the tax-related business party node 202 a. Therefore, the information isolated island among all roles related to tax is broken in cross-border trade, the working efficiency of tax-related business parties is greatly improved, and the technical effects of missed payment, wrong payment and other risks are reduced. And the technical problems that in the prior art, information communication among all business links is not smooth, so that tax-related business parties responsible for processing tax-related business have low working efficiency and high risks such as missed payment and wrong payment are solved.

In addition, it should be noted that the tax-involved business side node 202a may further send the cross-border trade data read from the blockchain 201 to the terminal device 100a of the tax-involved business side, and the terminal device 100a compares the cross-border trade data read from the blockchain 201 with the cross-border trade data included in the tax-involved request. Finally, the terminal device 100a sends the comparison result to the tax-related party node 202a, so that the tax-related party node 202a can handle the corresponding tax-related service according to the received comparison result.

Optionally, after processing the tax-related service, the method further includes: and writing tax-related service data information related to the tax-related service into the block chain.

Specifically, after the tax-related service party node 202a of the tax-related service party processes the tax-related service, since the tax-related service party node 202a is a node in the block chain system 200, the tax-related service party node 202a may directly write tax-related service data information related to the tax-related service into the block chain 201, and broadcast the newly generated block to each node of the block chain system 200, and based on the characteristics of the block chain 201, such as non-tamper property, decentralization, consensus mechanism, encryption, and the like, the cross-border trade data stored in the block chain 201 is more authentic. Therefore, by the mode, the security and the non-tampering property of tax-related business data information generated in a tax-related link are ensured, and the block chain 201 is convenient to form a distributed trade general ledger.

Specifically, the process of writing the tax-related service data information into the block chain 201 may be implemented, for example, by uplink-linking the tax-related service data information. Taking the tax-related service party node 202a as an example, when the tax-related service party node 202a performs uplink processing on the tax-related service data information, the tax-related service data information is broadcasted to each node 202a to 202n of the blockchain system 200 through the tax-related program module, so that the broadcasted tax-related service data information is temporarily cached in the transaction pool of each node 202a to 202 n.

Then, the block-out node in the blockchain system 200 packs the tax-related service data information from its own transaction pool into blocks, and broadcasts the blocks to the nodes 202 a-202 n of the blockchain system 200. Wherein the out-of-block node is the node that generated the block in each node 202 a-202 n of the blockchain system 200.

Therefore, after receiving the block broadcasted by the block node, the tax-related service party node 202a stores the block to the block chain 201 operated by the node through the tax-related program module, thereby implementing the uplink operation of the tax-related service data information and writing the tax-related service data information into the block chain 201.

The determination of the out-of-block node may be determined by a common consensus mechanism, such as a POW consensus mechanism, for example. For another example, the block chain system 200 in this embodiment may be in a form of a federation chain, and thus the block nodes may be determined in a specified manner.

Optionally, the operation of writing tax-related service data information related to the tax-related service into the block chain includes: and writing tax-related service data information into the block chain by utilizing a first program module in a plurality of preset program modules, wherein the plurality of program modules are respectively used for processing data information of different service links related to the cross-border trade service, and the first program module is used for processing tax-related service data related to the cross-border trade.

Specifically, fig. 4 shows a schematic diagram of the cross-border trade data management system of the related party of the cross-border trade data according to the embodiment. Referring to fig. 4, the business roles involved in the cross-border trade process are supply, import, purchase, forwarder, transportation, warehousing, customs clearance, shipper, bank, insurance, and customs business roles. Meanwhile, 10 major business links such as transaction, entrustment, transportation, storage, customs clearance, shipper, settlement, financing, insurance, tax involvement and the like are involved in the cross-border trade process. Therefore, the technical scheme of the present disclosure provides an API interface to different terminal devices of each business link, so that the terminal devices of the relevant parties of each business link can be docked with the tax-related business party node 202a through the API interface. For example: the supply, import and purchase links are butted with a transaction interface, the delivery link is butted with a commission interface, the transportation link is butted with a transportation interface, the storage link is butted with a storage interface, the customs link is butted with a customs interface, the delivery link is butted with a delivery interface, the bank link is butted with a settlement and financing interface, the insurance link is butted with an insurance interface, and the customs link is butted with a tax-related interface.

Similarly, the tax-related service node 202a is preset with a plurality of program modules for processing data information of different service links related to the cross-border trade service, respectively: the system comprises a transaction program module, a commission program module, a transportation program module, a storage program module, a customs clearance program module, a delivery program module, a settlement program module, a financing program module, an insurance program module and a tax-related program module. For example, the terminal device 100a of the tax-related business party interacts with the tax-related business party node 202a through application program interfaces (API interfaces) associated with different business links. So that tax-related business node 202a may utilize different program modules to write cross-border trade data to blockchain 201 or read cross-border trade data from blockchain 201.

Thus, the tax-related service side node 202a may use a tax-related program module (i.e., the first program module) of the plurality of program modules to write tax-related service data information generated during the transaction of the tax-related service into the block chain 201. In this way, the writing efficiency of the tax-involved business side node 202a is improved, and the complexity of the system is reduced.

Optionally, the operation of reading cross-border trade data of cross-border trades from the blockchain comprises: in the case where the blockchain running on the computing device includes cross-border trade data, the cross-border trade data is read from the blockchain running on the computing device.

Specifically, the tax-involved business side node 202a of the tax-involved business side may be a master node in the blockchain system 200, that is, the blockchain 201 running on the tax-involved business side node 202a stores all the cross-border trade data. In this case, the blockchain 201 running on the tax-related business side node 202a contains the cross-border trade data, so the tax-related business side node 202a can directly read the cross-border trade data from the blockchain 201 running on the tax-related business side node 202a, and does not need to interact with other nodes, thereby greatly improving the reading efficiency.

Optionally, the operation of reading cross-border trade data of cross-border trades from the blockchain comprises: in the event that the blockchain running on the computing device does not contain cross-border trade data, cross-border trade data is obtained from other nodes containing cross-border trade data.

Specifically, the tax-involved business side node 202a of the tax-involved business side may also store part of the cross-border trade data for a slave node in the blockchain system 200, i.e., the blockchain 201 running on the tax-involved business side node 202 a. In the case that the blockchain 201 running on the tax-involved business party node 202a does not contain the cross-border trade data, the tax-involved business party node 202a needs to interact with other blockchain nodes (for example, the customs party node 202e) storing the cross-border trade data, and acquire the cross-border trade data from the customs party node 202 e. Therefore, the accuracy and the safety of the acquired cross-border trade data are guaranteed.

Optionally, the operation of reading cross-border trade data of cross-border trades from the blockchain comprises: reading cross-border trade data recorded by a supplier of cross-border trade from the blockchain; reading cross-border trade data recorded by a buyer of the cross-border trade from the blockchain; reading cross-border trade data recorded by a transporter of the cross-border trade from the blockchain; reading cross-border trade data recorded by a warehousing party of cross-border trade from the blockchain; reading cross-border trade data recorded by a forwarder of cross-border trades from the blockchain; reading cross-border trade data recorded by a customs enterprise side of cross-border trade from the blockchain; reading cross-border trade data recorded by a carrier of the cross-border trade from the blockchain; reading cross-border trade data recorded by a financial service party of cross-border trade from the blockchain; reading cross-border trade data recorded by an insurance server of cross-border trade from the blockchain; and/or reading cross-border trade data recorded by import and export trade parties of cross-border trade from the blockchain.

Specifically, the business roles involved in the cross-border trading process include business roles such as supply, import, purchase, generation, transportation, storage, customs clearance, shipper, bank, insurance, customs, and the like, and the computing device of each business role may be a node in the blockchain system 200. For example, as shown in fig. 2A, the customs can record the cross-border trade data in the blockchain 201 through the customs node 202e, the forwarder can record the cross-border trade data in the blockchain 201 through the forwarder node 202h, and/or other business roles can record the cross-border trade data generated in the cross-border trade process in the blockchain 201 through their respective blockchain nodes, which is not described herein again. Thus, the tax-related business party node 202a reads the cross-border trade data recorded by the various business roles (stakeholders) from the blockchain 201. The data information generated in the cross-border trade process can not exceed the ten business links. And the ten business links can also ensure that respective data do not conflict, so that the situation that the data can be divided into two or more business links at the same time can be avoided. Since the types of the cross-border trade data related to different business links in the cross-border trade flow are different, the embodiment combines the correlation of the cross-border trade data of different types, and the ten program modules are arranged in the tax-related business side node 202 a. The tax-involved business side node 202a can completely process various cross-border trade data through the ten program modules, and can also ensure that a comprehensive principle is strictly followed and a non-conflict principle is strictly followed in the process of processing the cross-border trade data.

Optionally, the operation of reading cross-border trade data of cross-border trades from the blockchain comprises: and reading the cross-border trade data from the block chain by utilizing a second program module in a plurality of preset program modules, wherein the plurality of program modules are respectively used for processing data information of different business links related to the cross-border trade business, and the second program module is used for processing the cross-border trade data related to the cross-border trade.

As mentioned above, the business roles involved in the cross-border trade are, for example, the business roles of supply, import, purchase, generation, transportation, warehousing, customs clearance, courier, bank, insurance and customs, and the 10 major business links of transaction, commission, transportation, warehousing, customs clearance, courier, settlement, financing, insurance and tax involvement are involved in the cross-border trade. Thus, the tax-related business side node 202a is also correspondingly provided with a program module (i.e., a plurality of program modules) associated with 10 business links. The terminal device 100a interacts with the tax-related business party node 202 a. So that tax-related business side node 202a may utilize different program modules to read cross-border trade data from blockchain 201.

Therefore, as shown in fig. 2A and fig. 4, the forwarder may request the customs service to transact the corresponding customs service, and then the customs service may record the customs data information generated during the transaction of the customs service in the blockchain 201 through the customs node 202 e. Then, the terminal device 100e of the customs side sends the tax-related request to the terminal device 100a of the tax-related service side, and the terminal device 100a forwards the tax-related request to the node 202a of the tax-related service side. In this case, the tax-related business side node 202a reads the clearance data information from the blockchain 201 using a second program module (i.e., corresponding to the clearance program module in fig. 4) set in advance. Thus, the tax-involved business party node 202a may read the corresponding cross-border trade data using the program module corresponding to the business link to which the cross-border trade data belongs. In addition, the tax-related business party node 202a may also utilize the transaction program module to read the cross-border transaction data recorded by the buyer and the seller of the cross-border transaction from the blockchain 201. Therefore, the reading efficiency of the cross-border trade data is greatly improved.

Optionally, the blockchain includes a first blockchain and a plurality of second blockchains respectively corresponding to different business links, where the first blockchain is associated with the plurality of second blockchains, and the operation of reading the cross-border trade data from the blockchain by using a preset second program module includes: and reading the cross-border trade data from a second block chain corresponding to the business link to which the cross-border trade data belongs by using a second program module.

Specifically, the blockchain 201 includes a first blockchain and a plurality of second blockchains respectively corresponding to different business links. The plurality of second blockchains are respectively used for storing cross-border trade data related to different business links, the first blockchain is used for storing all data related to each business link in the cross-border trade process, and the first blockchain is associated with the plurality of second blockchains. Fig. 5 shows a schematic diagram of the components of the tax-related business node 202 a. Referring to fig. 5, a first block chain and a plurality of second block chains are run on the tax-related business side node 202 a. Illustratively, according to the above, the customs can write the customs data information related to the customs service to the second blockchain 10 in the blockchain 201 through the customs node 202 e. Wherein the second blockchain 10 is used for storing the customs data related to the customs links involved in each business role. Therefore, after the tax-related business node 202a receives the tax-related request, the cross-border trade data is read from the second blockchain 10 in the blockchain 201 by using the preset second program module (i.e., corresponding to the clearance program module in fig. 5). Therefore, the efficiency of reading the cross-border trade data is greatly improved, and the complexity of the system is reduced. Further, referring to fig. 5, the program modules corresponding to different business links on the tax-related business side node 202a correspond to different second blockchains, respectively. The tax-related service side node 202a may thus write data into or read data from the corresponding second block chain, respectively, by referring to each program module. Thereby improving the efficiency of cross-border trade data access.

Optionally, the operation of writing tax-related service data information related to the tax-related service into the block chain includes: and setting the authority of the node for reading the tax-related service data information.

Specifically, in the operation of writing the tax-related service data information related to the tax-related service into the block chain 201, the tax-related service data information may be set to have a read right. For example: the tax-related service party node 202a encrypts the tax-related service data by using the public key of the authorization node in the process of writing the data. The encrypted tax-related service data can be decrypted only by using the private key in the authorization node, and the tax-related service data information is read. That is, only the node user of the authorized node has the right to read the tax-related service data information. Thereby guaranteeing the privacy of the data.

Optionally, the block chain includes a first block chain and a plurality of second block chains respectively corresponding to different service links, where the first block chain is associated with the plurality of second block chains, and the operation of writing the tax-related service data information into the block chain by using a preset first program module includes: and writing the tax-related service data information into a second block chain corresponding to the service link to which the tax-related service data information belongs by using the first program module.

Specifically, referring to fig. 5, the blockchain 201 includes a first blockchain and a plurality of second blockchains respectively corresponding to different service links. The plurality of second blockchains are respectively used for storing cross-border trade data related to different business links, the first blockchain is used for storing all data related to each business link in the cross-border trade process, and the first blockchain is associated with the plurality of second blockchains. The second block chain 20 is configured to store tax-related service data information generated by a tax-related service party in the process of processing a tax-related service. Accordingly, the tax-related business node 202a may write tax-related business data information into the second blockchain 20 of the blockchain 201 using the first program module (i.e., tax-related program module). Through the mode, the cross-border trade data related to different business links are respectively stored in different second block links, so that the accuracy and the non-tampering property of the stored cross-border trade data are guaranteed, and the efficiency of reading the post-stage cross-border trade data is also guaranteed.

That is, in the present embodiment, the storage of cross-border trade data can be realized by combining the blockchain main chain and the blockchain sub-chain. Wherein the first blockchain is the main chain and the second blockchain is the sub-chain. And wherein a child chain may also be viewed as a separate blockchain data structure.

That is, the blockchain system 200 of the present embodiment is different from the conventional blockchain system. In a conventional blockchain system, each node usually operates a blockchain. However, in the present embodiment, each block link point of the block chain system is operated with a plurality of block chains, one of which is a main chain and the other is a sub-chain. In addition, each blockchain system is provided with different blockchain identification information, for example, as shown in the following table:

therefore, in this embodiment, the main chain is used to store all cross-border trade data, and each sub-chain is used to store cross-border trade data corresponding to different business links. Thus, referring to fig. 5, the program module corresponding to each business link may access the corresponding sub-chain and may perform a blockchain operation corresponding to the corresponding sub-chain.

In addition, correspondingly, in the blockchain system 200 of the present embodiment, different identification information is defined for the cross-border trade data of different business links for identification. The identification information may advantageously correspond to the identification information of the child chain. For example, the identification information of the cross-border trade data of the transaction link is "01", the identification information of the cross-border trade data of the commission link is "02", the identification information of the cross-border trade data of the transportation link is "03", the identification information of the cross-border trade data of the storage link is "04", the identification information of the cross-border trade data of the customs link is "05", the identification information of the cross-border trade data of the delivery link is "06", the identification information of the cross-border trade data of the settlement link is "07", the identification information of the cross-border trade data of the financing link is "08", the identification information of the cross-border trade data of the insurance link is "09", and the identification information of the cross-border data of the tax link is "0A".

Still taking the tax-related service party node 202a as an example, when the terminal device 100a of the tax-related service party links up the tax-related service data information, the terminal device 100a of the tax-related service party calls an API interface corresponding to the "tax-related" link, so as to transmit the tax-related service data information that needs to be linked up to the tax-related service party node 202 a. After the tax-related business side node 202a receives the tax-related business data information through the tax-related program module, the identification information "0A" is added to the tax-related business data information, and the information is broadcasted in the block chain system 200.

After receiving the tax-related service data information broadcast by the tax-related service party node 202a, each block chain node 202 a-202 n buffers the tax-related service data information in a respective transaction pool. The block-out node in the blockchain system 200 then reads the tax-related service data information from the transaction pool and generates a corresponding data block. The method for determining the block node to go out is not limited. For example, since the blockchain system 200 operates in each blockchain, the main chain stores all data. The block nodes can be determined from the sequence numbers of the blocks of the main chain. The out-of-block node that generates the new backbone block may be determined, for example, by a POW consensus mechanism. Or determining the block node according to the block number of the current main chain block. Or to designate a particular blockchain node of the blockchain system 200 as an out-block node.

Then, the out-of-block node reads the identification information "0A" from the tax-related service data information. It can thus be determined that the newly generated chunk is to be stored not only in the main chain, but also in the child chain with the blockchain identification "0A". Thus, for example, the out-blocking node may generate a main chain block for the main chain, add the identifier "00" of the main chain to the main chain block, then generate a sub-chain block for the sub-chain with the block chain identifier "0A", and add the identifier "0A" to the sub-chain block. The egress node then broadcasts the main chain block and the child chain blocks to the various nodes 202 a-202 n of the blockchain system 200.

Then, after receiving the main chain block and the sub-chain blocks, the tax-related service party node 202a writes the main chain block into the main chain according to the identification information in the blocks, and writes the corresponding sub-chain blocks into the corresponding sub-chains, thereby completing the data uplink operation and writing the tax-related service data information into the block chain.

Alternatively, as another way of blocking, the blocking node may generate only one block, but add the identifier "0A" of the corresponding child chain to the block and broadcast the generated block to each node 202 a-202 n of the blockchain system 200. The tax-related business node 202a then first writes the block into the backbone upon receiving the block. And then, writing the blocks into the corresponding sub-chains according to the identifier '0A', thereby completing the uplink operation of the data and writing the tax-related service data information into the block chain.

Further, referring to fig. 1, according to a second aspect of the present embodiment, there is provided a storage medium. The storage medium comprises a stored program, wherein the method of any of the above is performed by a processor when the program is run.

Thus, according to this embodiment, the tax-involved business node 202a of the tax-involved business first receives a tax-involved request related to the cross-border trade, then, in response to the tax-involved request, reads the cross-border trade data of the cross-border trade from the blockchain 201, then, compares the read cross-border trade data with the cross-border trade data included in the tax-involved request, and finally, processes the tax-involved business in the case that the cross-border trade data read from the blockchain 201 matches the cross-border trade data included in the tax-involved request. Due to the characteristics of non-tamper property, decentralization, common recognition mechanism, encryption and the like of the block chain 201, the whole cross-border trade flow chain can be integrated, and information synchronization and interconnection are realized. The tax-related business parties do not need to read cross-border trade data from each business link respectively and then conduct corresponding tax-related business handling, but directly read cross-border trade data generated in the cross-border trade process of each business link from the block chain 201 through the tax-related business party node 202 a. Therefore, the information isolated island among all roles related to tax is broken in cross-border trade, the working efficiency of tax-related business parties is greatly improved, and the technical effects of missed payment, wrong payment and other risks are reduced. And the technical problems that in the prior art, information communication among all business links is not smooth, so that tax-related business parties responsible for processing tax-related business have low working efficiency and high risks such as missed payment and wrong payment are solved.
