Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a block chain system according to an embodiment of the present invention. Referring to fig. 1, the blockchain system includes at least one first node device 101, at least one second node device 102, at least one third node device 103, and a policing node device 104.
The first node equipment is used by reimbursement enterprises and is used for reimbursing electronic bills, transferring electronic bills and marking the bills, and the reimbursement enterprises are the enterprises reimbursement invoices. When the first node device receives the status marking request sent by the second node device, the electronic bill indicated by the status marking request can be marked, and the marking completion is fed back to the second node device, so that the second node device can continue the flow of processing the electronic bill.
The second node device is a device used by the merchant and used for generating a second electronic bill, the second electronic bill can be regarded as a red invoice issued by the merchant and used for offsetting an error electronic bill generated before the merchant, and when the second node device receives an electronic bill processing request, the second node device can generate a corresponding second electronic bill based on the electronic bill processing request so as to issue a corresponding red invoice.
The third node device is a device used by the consumer and is used for sending an electronic bill processing request to the second node device so that the second node device can generate a second electronic bill, and in addition, the third node device can also receive the second electronic bill sent by the second node device.
The supervising node device is a device used by the tax authority for providing the second node device with a key of the tax authority so that the second node device has the right to transfer the electronic ticket.
In order to embody the process of processing the electronic ticket before the second node device reimburses the electronic ticket, referring to fig. 2, fig. 2 is a flowchart of an electronic ticket processing method provided by an embodiment of the present invention, and the method specifically includes:
201. and the second node equipment receives the electronic bill processing request, wherein the electronic bill processing request carries the bill identification and the processing type of the first electronic bill.
The electronic bill processing request is used for indicating that the first electronic bill is processed and generating a second electronic bill, and the electronic bill processing request can also carry an identifier for indicating that the electronic bill is not reimbursed so as to indicate that the first electronic bill to be processed by the second node device is not reimbursed.
The first electronic ticket may be considered a blue invoice previously issued by the merchant to the consumer, however, the data on the first electronic ticket does not match the actual transaction situation. The ticket identifier of the first electronic ticket is used to indicate the first electronic ticket, and the ticket identifier of the first electronic ticket may include a code, a number, and a verification code of the first electronic ticket, and certainly, the ticket identifier of the first electronic ticket may also be used to indicate other contents of the first electronic ticket.
The processing type is any one of a cancel ticket and a modification ticket, when the first electronic ticket corresponds to a transaction cancel operation, the processing type is the cancel ticket, and when the content of the first electronic ticket is wrong, the processing type is the modification ticket. Different processing types can be represented by different character strings, for example, a revocation ticket is represented by 0, and a modification ticket is represented by 1.
The transaction cancelling operation can be represented as a goods returning operation of the consumer, and the goods returned are the goods recorded in the transaction data corresponding to the first electronic bill. A content error of the first electronic ticket may be represented as an amount error in the first electronic ticket, for example, when the merchant and the consumer transact, the consumer pays 10 dollars, but the amount on the first electronic ticket generated by the merchant is 5 dollars, then the amount on the first electronic ticket does not match the actual transaction amount, and the amount in the first electronic ticket is an amount error. The content error of the first electronic bill can also be expressed as head-up or tax rate error in the first electronic bill. The embodiment of the present invention does not specifically limit the content of the error in the first electronic ticket.
Because the content of the first electronic bill includes multiple conditions by mistake, in some embodiments, the electronic bill processing request may further carry modified content, where the modified content is the modified content on the first electronic bill, and may be a money amount, a head-up or a tax rate, and the like, so that the second node device may generate a correct electronic bill according to the target content.
The second node device receives the electronic bill processing request, and can be in any mode of modes 1-2.
In the mode 1, the electronic bill processing request is triggered through the transaction related operation of the merchant on the second node device, so that the second node device receives the electronic bill processing request.
When the content of the first electronic bill is wrong or the transaction corresponding to the first electronic bill is cancelled, the consumer communicates with the merchant on line, and the consumer requests the merchant to process the first electronic bill, so that after the communication between the consumer and the merchant is completed, the merchant triggers the second node device to receive the electronic bill processing request by clicking the billing button on the second node device. The billing button may be a real button on the second node device for triggering the electronic ticket processing request, or may be a virtual button on a billing interface of the second node device, and of course, the billing interface may also be a processing type selection button, after determining the processing type according to the processing type selection button, the merchant inputs the target content in the input box corresponding to the target content, and may click the billing button to trigger the electronic ticket processing request, so that the second node device receives the electronic ticket processing request.
In the mode 2, the second node device receives an electronic bill processing request sent by the third node device.
When the content of the first electronic bill is wrong or the transaction corresponding to the first electronic bill is cancelled, the consumer can trigger the third node device to send the electronic bill processing request to the second node device through the billing button on the third node device, and then the second node device can receive the electronic bill processing request. The billing button on the third node device is the same as the billing button on the second node device, and the embodiment of the present invention does not repeat the billing button on the third node device.
202. And the second node equipment inquires the billing record according to the bill identification of the first electronic bill.
The billing record is used for recording electronic bills corresponding to the transaction performed by the merchant, and the electronic bills generated by the second electronic node device can be stored in the billing record, and each electronic bill corresponds to a bill identifier in the billing record.
The second node device verifies whether the first electronic bill indicated by the electronic bill processing request is generated according to the transaction of the merchant corresponding to the second node device by inquiring whether the record of the first electronic bill is stored in the billing record, when the billing record stores the record corresponding to the first electronic bill, the first electronic bill is the electronic bill generated by the merchant through the second node device, the second node device can continue the subsequent processing flow of the first electronic bill, and when the record corresponding to the first electronic bill is not stored in the billing record, the first electronic bill is not the electronic bill generated by the merchant through the second node device, the second node device does not need to process the first electronic bill.
203. When the processing type is the revocation bill, if the record corresponding to the first electronic bill is stored in the billing record, the second node device acquires the key of the supervision node device.
The billing record stores a record corresponding to the first electronic bill, and can be represented as that the billing record stores a bill identifier carried by the electronic bill processing request, or as that the billing record stores the first electronic bill indicated by the bill identifier in the electronic bill processing request.
The key of the supervisory node device comprises a first key and a second key, wherein the first key is used for providing the ticket sending authority, and the second key is used for providing the ticket transferring authority.
The second node device may obtain the first key of the supervisory node device by sending a first key obtaining request to the supervisory node device, and in a possible implementation manner, the second node device may obtain the first key of the supervisory node device by a process shown in step 20311 and 20314 described below.
Step 20311, the second node device sends a first key obtaining request to the supervisory node device, where the first key obtaining request is used to obtain the first key of the supervisory node device.
The first key obtaining request may carry a node identifier of the second node device and an identifier of the first key, where the identifier of the first key is used to indicate the first key, the first key is used to open an authority to send the ticket to the first address, and the first address is the first address in step 205.
The node identifier of the second node device is used to indicate the second node device, and the node identifier of the second node device may be a public key or an address of the second node device, so that the supervising node device may verify the first key acquisition request.
Step 20312, after receiving the first key obtaining request, the supervisory node device verifies the node identifier in the first key obtaining request.
When the blockchain system is initialized, the supervising node device stores node identifiers of the second node devices, so that the supervising node device can verify the acquired first key acquisition request. The supervising node device may verify the node identification in the first key acquisition request by querying the node identifications of all second node devices stored by the supervising node device. In a possible implementation manner, when the supervising node device queries the node identifier in the first key obtaining request from the stored node identifiers of all the second node devices, the node identifier passes the verification, otherwise, the node identifier does not pass the verification. Then, when the node identification in the first key acquisition request is verified, the first key acquisition request is verified.
Step 20313, when the node identifier in the first key obtaining request is verified, the supervising node device sends the first key of the supervising node device to the second node device.
Step 20314, the second node device receives the first key of the supervisory node device sent by the supervisory node device.
The second node device may obtain the second key of the supervisory node device by sending a second key obtaining request to the supervisory node device, and in a possible implementation manner, the second node device may obtain the second key of the supervisory node device by a process shown in step 20321 and 20324 described below.
Step 20321, the second node device sends a second key obtaining request to the supervisory node device, where the second key obtaining request is used to obtain a second key of the supervisory node device.
The second key obtaining request carries a node identifier of the second node device and an identifier of the second key, and the identifier of the second key is used for indicating the second key.
Step 20322, after receiving the second key obtaining request, the supervisory node device verifies the node identifier in the second key obtaining request.
This step 20322 is similar to the process in which the supervisory node device verifies the node identifier in step 20312, and this embodiment of the present invention does not describe this step 20322 again.
Step 20323, when the node identifier in the second key obtaining request is verified, the supervising node device sends the second key of the supervising node device to the second node device.
At step 20324, the second node device receives the supervising node device's second key sent by the supervising node device.
It should be noted that, in some embodiments, only the second node device storing the node identifier in the supervisory node device can send the first key acquisition request or the second key acquisition request to the supervisory node device, that is, the supervisory node device can only receive the first key acquisition request or the second key acquisition request sent by the second node device corresponding to the stored node identifier, and then, after receiving the first key acquisition request or the second key acquisition request, the supervisory node device may also not verify the node identifier in the first key acquisition request or the second key acquisition request, but directly send its own first key or second key to the second node device, so as to improve the efficiency of the second node device in acquiring the first key or the second key.
It should be noted that, when the processing type is a modified ticket, if the record corresponding to the first electronic ticket is stored in the billing record, the second node device compares the content of the sub-record corresponding to the first electronic ticket in the transaction record with the content of the first electronic ticket one by one, and when the content of the sub-record corresponding to the first electronic ticket in the transaction record does not match the content corresponding to the first electronic ticket, the second node device obtains the key of the monitoring node device.
The transaction records are used for storing transactions made by merchants and consumers, each transaction corresponds to one sub-record in the transaction records, that is, each sub-record in the transaction records is used for storing the transaction condition of one transaction, and the transaction condition can include the bill identification of an electronic bill, the amount, time, goods, invoice heading, tax rate and the like of the transaction.
When the content of the sub-record corresponding to the first electronic bill in the transaction record does not match the content corresponding to the first electronic bill, it indicates that the content in the first electronic bill is wrong, for example, the amount of money in the first electronic bill is 5, and the amount of money in the sub-record corresponding to the first electronic bill is 10, then the content in the sub-record corresponding to the first electronic bill is wrong. The amount of money in the first electronic ticket is wrong.
The second node device can also directly compare the target content in the electronic bill processing request with the target content in the sub-record corresponding to the first electronic bill in the transaction record, and when the target content in the electronic bill processing request does not accord with the target content in the sub-record corresponding to the first electronic bill, the second node device obtains the key of the supervision node device.
The billing record and the transaction record may be stored in the memory of the second node device, may also be stored in other storage devices, such as a mobile hard disk, and may also be stored in the cloud. The embodiment of the invention does not specifically limit the storage place and the recording mode of the invoicing record and the transaction record.
It should be noted that, in the process shown in step 202 and 203, the process is a process of further verifying the electronic ticket processing request and acquiring the key of the supervisory node device for the second node device, that is, when any content stored in the billing record and corresponding to the first electronic ticket or the sub-record corresponding to the first electronic ticket does not conform to the content corresponding to the first electronic ticket, the electronic ticket processing request passes the verification, and then the second node device acquires the key of the supervisory node device, otherwise, the electronic ticket processing request does not pass the verification, and then the second node device cannot acquire the key of the supervisory node device.
Then, whether the electronic bill processing request is correct or not can be further verified through the steps 202 and 203, so that the wrong electronic bill processing request can be prevented from being processed, and the error rate of processing the electronic bill processing request by the second node device can be further reduced.
204. The second node device generates a second electronic ticket in the blockchain system based on the first electronic ticket indicated by the ticket identification and the processing type.
When the processing type is the modification bill and the modification content carried by the electronic bill processing request is the amount of money, the modification bill is used for modifying the amount of money on the first electronic bill at the moment, and the amount of money on the first electronic bill only needs to be partially offset, so that the amount of money in the second electronic bill generated by the second node device is a negative value of the difference value between the amount of money in the first electronic bill and the target content, and other contents in the second electronic bill are consistent with other contents in the first electronic bill.
When the processing type is the modification bill and the modification content carried by the electronic bill processing request is not the amount of money, at this time, the modification bill is to modify other content on the first electronic bill, and all the content on the first electronic bill needs to be cancelled, so the amount of money in the second electronic bill generated by the second node device is a negative value of the amount of money in the first electronic bill, and the other content in the second electronic bill is consistent with the other content in the first electronic bill.
When the processing type is the revocation bill, the revocation bill is to revoke all the contents on the first electronic bill in order to revoke the first electronic bill, so the amount of money in the second electronic bill is the negative value of the amount of money in the first electronic bill, and other contents in the second electronic bill are identical to other contents in the first electronic bill.
205. And the second node equipment sends the second electronic bill to a first address in the blockchain system based on the key of the supervision node equipment in the blockchain system, wherein the first address is an address multiply signed based on the supervision node equipment and a bill object of the electronic bill processing request.
The first address is a virtual address in the block chain system and is used for storing a second electronic bill generated by the second node equipment, a invalidated first electronic bill and a modified third electronic bill. The ticket object of the electronic ticket processing request is a consumer who carries out the transaction corresponding to the first electronic ticket with the merchant.
The multi-signed address based on the supervising node device and the ticket object of the electronic ticket processing request may be expressed as the first address having an association relationship with the key of the supervising node device, the key of the third node device, and the key of the second node device. The owner of the key associated with the multi-signed address has both access to the multi-signed address and the authority to transfer electronic tickets within the multi-signed address. When the electronic bill transfer needs to be carried out in the multiple signature addresses, at least one secret key associated with the multiple signature addresses is needed to transfer the electronic bill in the multiple signature addresses.
Since different keys of the supervisory node device may provide different authorities, where the first key is used for providing authority to send the ticket, the second node device needs to acquire the first key of the supervisory node device before sending the second electronic ticket to the first address, and the second node device may acquire the first key of the supervisory node device through the process shown in step 20311 and 20314.
206. The second node device transfers the first electronic bill stored in the second address to the first address based on the key of the supervisory node device in the block chain system, adds a first mark to the first electronic bill which does not carry a mark, adds the bill identifier of the second electronic bill to the first electronic bill stored in the first address, and the first mark is used for indicating that the first electronic bill is invalidated.
The second address may be a virtual address in a blockchain system for storing a plurality of electronic tickets, each electronic ticket associated with a consumer account, an electronic ticket may appear as an electronic version of a blue invoice in the corresponding consumer account. Of course, the second address may also be an address of a third node device that sends the electronic ticket processing request, and the second address is not specifically limited in the embodiment of the present invention.
Since different keys of the supervisory node device may provide different rights, where the second key is used for providing the right to transfer the ticket, the second node device needs to acquire the second key of the supervisory node device before transferring the first electronic ticket to the first address, and the second node device may acquire the first key of the supervisory node device through the process shown in step 20322 and 20324.
It should be noted that the second node device can only have the right to transfer the first electronic ticket to the first address after acquiring the second key of the supervisory node device, and the step of acquiring the second key of the supervisory node device by the second node device may be between step 205 and step 206, or before step 205, and the execution sequence of the step of acquiring the second key of the supervisory node device and step 205 is not specifically limited in the embodiment of the present invention.
After the first electronic bill is transferred to the first address, the second node device adds the first mark to the first electronic bill which does not carry the mark, the second node device may add the first mark in the target field of the first electronic bill, and the first mark may be any character string. The target field may be any free field in the first electronic ticket, or may be a field added in the first electronic ticket.
Then, when the first electronic bill has the first mark, it indicates that the first electronic bill is invalid.
The ticket identifier of the second electronic ticket is a code, a number, and a verification code of the second electronic ticket, and may also be other information indicating the second electronic ticket.
The second node device may add the ticket identifier of the second electronic ticket to the remark information field in the first electronic ticket, or may add the ticket identifier of the second electronic ticket to other fields. The ticket identification of the second electronic ticket is added in the first electronic ticket, so that the first electronic ticket and the second electronic ticket can correspond to each other for later verification.
It should be noted that, in this step 206, the second node device transfers the first electronic ticket stored in the second address to the first address based on the key of the supervising node device in the blockchain system, and adds the process shown by the first mark to the first electronic ticket without carrying a mark, that is, the second node device adds the first mark process to the first electronic ticket stored in the first address.
207. And when the processing type is the modification bill, the second node equipment generates a third electronic bill according to the modification content carried by the electronic bill processing request.
The second electronic device can replace the target content on the first electronic bill with the modified content carried by the electronic bill processing request to obtain a third electronic bill, wherein the target content is wrong content of the first electronic bill, and other content in the third bill is consistent with other content in the first electronic bill.
208. The second node device sends the third electronic bill to the first address based on the key of the supervisory node device in the blockchain system.
Before the second node device sends the third ticket to the first address, the second node device needs to acquire the first key of the supervisory node device again, and the second node device can send the third electronic ticket to the first address based on the acquired first key of the supervisory node device.
It should be noted that, when the processing type is modified ticket reimbursement, the second node device will execute the step 207- "208, and when the processing type is void ticket, the second node device will not execute the step 207-" 208.
209. The second node device adds the bill identification of the first electronic bill to the second electronic bill stored in the first address, and outputs the second electronic bill and the third electronic bill carrying the bill identification of the first electronic bill.
The second node device can add the bill identification of the first electronic bill in the field of the second electronic bill for recording remark information so as to add the bill identification of the first electronic bill in the second electronic bill, and further can establish the corresponding relation between the second electronic bill and the first electronic bill so as to be verified in the future.
The first node device can output the second electronic bill and the third electronic bill by sending the second electronic bill and the third electronic bill to the second address storing the first electronic bill.
When the second address is a virtual address, the second node equipment directly sends the second electronic bill and the third electronic bill to a position for storing the first electronic bill; and when the second address is the address of the third node device, the second node device sends the second electronic bill and the third electronic bill to the third node device.
When the second address has an access right, the second node device can send the second electronic bill and the third electronic bill to the second address only when the second address has the access right, for example, the second address is set with the access right by a consumer, the second node device sends a bill issuing request to the second address, the bill issuing request carries the second electronic bill and the third electronic bill, when the consumer refuses to receive the bill issuing request through the third node device, the second node device cannot send the second electronic bill and the third electronic bill to the second address, and when the consumer receives the bill issuing request through the third node device, the second node device can send the second electronic bill and the third electronic bill to the second address.
It should be noted that, when the processing type is a revocation bill, the second node device does not generate the third electronic bill, and does not output the third electronic bill. In addition, the first electronic bill is invalidated, the second node equipment generates a second electronic bill for punching and selling the first electronic bill and generates a third electronic bill, so that the second electronic bill and the third electronic bill can replace the first electronic bill, and the red punching of the bills is realized. To further illustrate the process of reimbursement ticket reimbursement, refer to the flowchart of the reimbursement ticket reimbursement method shown in fig. 3 according to the embodiment of the present invention, which specifically includes the following steps 3.1-3.4.
And 3.1, initiating the red rushing to the billing enterprise by the consumer on line.
When a consumer initiates a red punching on a first bill to an invoicing enterprise on line, the invoicing enterprise knows that the red punching on the first electronic bill is needed, which is equivalent to the step 201 in which the second node device receives an electronic bill processing request sent by the third node device.
And 3.2, the billing enterprise calls the first secret key of the tax authority through the second node device and issues the second electronic bill to the multiple signature address (the tax authority and the consumer).
Wherein, the (tax authority + consumer) multiple signature address is the first address.
And 3.3, calling a second secret key of the tax authority by the second node device, transferring the first electronic bill to the (tax authority + consumer) multiple signature address, and printing a red-flushing state on the first electronic bill.
And the second node device marks the red punching state on the first electronic bill to be equivalent to the first mark on the first electronic bill.
And 3.4, the second node device calls the first secret key of the tax authority, and re-issues a new third electronic bill to the (tax authority + consumer) multiple signature address according to the processing type (whether the information in the first electronic bill is modified or the goods are returned) to realize re-invoicing, and the second node device reuses a normal invoicing interface when invoicing so as to execute the step 202 and the step 209.
It should be noted that steps 3.2-3.4 are performed in the blockchain system.
For further explanation of the red punching process of the present invention, refer to a schematic diagram of a logic design for performing red punching as shown in fig. 4 provided in the embodiment of the present invention.
As can be seen from fig. 4, the consumer communicates with the merchant offline, the consumer indicates that the blue invoice (the blue invoice is equivalent to the first electronic bill) needs to be red-stamped, the merchant opens an applet or a PC (personal computer) management terminal on the second node device, the applet or the PC management terminal is operated to determine whether the return red stamping is the return red stamping (the return red stamping is equivalent to the waste bill), if the return red stamping is the return red stamping, the applet or the PC management terminal issues a red invoice (the red invoice is equivalent to the second electronic bill) to the consumer, the amount on the red invoice is negative, the number of the original blue invoice (the original blue invoice is equivalent to the first electronic bill) is remarked, the red stamping is marked on the original blue invoice (the marking red stamping is equivalent to the marking of the first mark), and a new red invoice number (the invoice number of the invoice is equivalent to the bill marking) is added on the stock red invoice, the consumer returns the goods to the merchant, who returns the money to the consumer. If the bill is not returned, the bill is wrongly issued (the bill is wrongly issued and is equivalent to the modified bill), which is represented as the wrong head raising, the amount of money or the tax rate on the blue-character bill, a small program or a PC management end is operated, a red-character bill is issued to the consumer, the amount of money on the red-character bill is negative, the number of the original blue-character bill is remarked, the red bill is marked on the original blue-character bill, a merchant directly inserts a correct blue-character bill (the correct blue-character bill is equivalent to the third electronic bill) into the account of the consumer, and the original wrong blue-character bill is not displayed for the consumer any more.
The method provided by the embodiment of the invention sends the generated second electronic bill to the first address through the processing type, the first secret key and the second secret key in the electronic bill processing request, transfers the first electronic bill to the first address, invalidates the first electronic bill in the first address and outputs the second electronic bill, so that the process of processing the electronic bill is not required for a consumer to go to a tax authority to make a relevant certificate, nor for the consumer to provide the relevant certificate made by the tax authority to a merchant, and the process of participation of the consumer is reduced, therefore, the process of processing the electronic bill is simpler for the consumer, namely the process of making a red-word invoice is simpler, so the process of processing the electronic bill can be independently completed by the second node device, the consumer does not need to go to the tax authority to make a relevant certificate, and the consumer does not need to provide the relevant certificate made by the tax authority to the merchant, the participation process of the consumer is reduced, so that the process of processing the electronic bill is simpler for the consumer, namely the process of issuing the red invoice is simpler. Moreover, the supervision node device can directly send the own first key and second key to the second node device without verifying the node identifiers in the first key acquisition request and the second key acquisition request, so that the efficiency of acquiring the first key and the second key by the second node device is improved, and whether the electronic bill processing request is correct or not can be further verified by inquiring the billing record and the consumption record, so that the wrong electronic bill processing request is avoided to be processed, and the error rate of processing the electronic bill processing request by the second node device is reduced. And by adding the bill identification of the second electronic bill in the first electronic bill, the first electronic bill can be made to correspond to the second electronic bill for later verification. And the second node device can add the note identifier of the first electronic note in the field of the second electronic note for recording the remarking information so as to add the note identifier of the first electronic note in the second electronic note, and further can establish the corresponding relation between the second electronic note and the first electronic note so as to be checked later.

502. And the second node equipment inquires the billing record according to the bill identification of the first electronic bill.
The process of step 502 is the same as the process shown in step 202, and the process of step 502 is not described in detail in this embodiment of the present invention.
503. When the processing type is a modified bill, if the record corresponding to the first electronic bill is stored in the billing record, the second node device compares the content of the sub-record corresponding to the first electronic bill in the transaction record with the content of the first electronic bill one by one, and when the content of the sub-record corresponding to the first electronic bill in the transaction record does not conform to the content corresponding to the first electronic bill, the second node device obtains the key of the monitoring node device.
The second node device can also directly compare the target content in the electronic bill processing request with the target content in the sub-record corresponding to the first electronic bill in the transaction record, and when the target content in the electronic bill processing request does not accord with the target content in the sub-record corresponding to the first electronic bill, the second node device obtains the key of the supervision node device.
It should be noted that, when the processing type is a revocation ticket, if the record corresponding to the first electronic ticket is stored in the billing record, the second node device obtains the key of the supervisory node device.
Step 502-.
Whether the electronic bill processing request is correct can be further verified through the steps 502 and 503, so that the wrong electronic bill processing request can be prevented from being processed, and the error rate of processing the electronic bill processing request by the second node equipment is further reduced.
504. When the electronic bill processing request carries a third mark, the second node device sends a state mark request to the first node device, wherein the state mark request is used for indicating bill transfer and marking, and the third mark is used for indicating that the first electronic bill has been reimbursed.
When the second node device receives the electronic ticket processing request, it will detect the content requested by the electronic ticket processor, and when the third mark is detected in the electronic ticket processing request, the second node device will execute this step 504.
