Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Fig. 1 is a schematic diagram of a blockchain system provided by 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 supervisory node device 104 .

Wherein, the first node device is the device used by the reimbursement enterprise, and is used for reimbursement of electronic bills, transfer of electronic bills and marking of bills, and the reimbursement enterprise is an enterprise that reimburses invoices. When the first node device receives the status marking request sent by the second node device, it can mark the electronic note indicated by the status marking request, and feedback the marking completion to the second node device, so that the second node device can continue The process of electronic bill processing.

The second node device is the device used by the merchant to generate the second electronic bill. The second electronic bill can be regarded as a red-letter invoice issued by the merchant. It is used to reverse the wrong electronic bill generated by the merchant. When the second node device receives When an electronic bill processing request is received, a corresponding second electronic bill may be generated based on the electronic bill processing request, so as to issue a corresponding red-letter invoice.

The third node device is a device used by consumers, and is used to send an electronic bill processing request to the second node device so that the second node device can generate the second electronic bill. In addition, the third node device can also receive the request sent by the second node device. the second electronic note.

The supervisory node device is used by the tax authority, and is used to provide the key of the tax authority to the second node device, so that the second node device has the authority to transfer the electronic bill.

The above is the description of the blockchain system and each node device. Before the first electronic bill is reimbursed, the second node device can process the wrong first electronic bill. In order to reflect that the second node device processes the electronic bill before reimbursement process, see Figure 2, Figure 2 is a flow chart of an electronic bill processing method provided by an embodiment of the present invention, the method specifically includes:

201. The second node device receives an electronic receipt processing request, where the electronic receipt processing request carries the receipt identification and processing type of the first electronic receipt.

The electronic bill processing request is used to instruct to process the first electronic bill and generate a second electronic bill, and the electronic bill processing request may also carry an identifier indicating that the electronic bill has not been reimbursed to indicate that the second node device The first electronic note to be processed has not been reimbursed.

The first electronic bill can be regarded as the blue letter invoice issued by the merchant to the consumer before, but the data on the first electronic bill does not match the actual transaction situation. The note identification of the first electronic note is used to indicate the first electronic note. The note identification of the first electronic note may include the code, number and verification code of the first electronic note. Of course, the note identification of the first electronic note also It may be other content used to indicate the first electronic note, and the embodiment of the present invention does not specifically limit the note identifier of the first electronic note.

The processing type is either a voided note or a revised note. When the first electronic note corresponds to a transaction cancellation operation, the processing type is a voided note. When the content of the first electronic note is incorrect, the processing type is a revised note. Different processing types can be represented by different character strings, for example, 0 is used to represent a voided ticket, and 1 is used to represent a modified ticket. The embodiment of the present invention does not specifically limit the character string representing the processing type.

Wherein, the transaction cancellation operation may be expressed as a consumer's return operation, and the returned goods are the goods recorded in the transaction data corresponding to the first electronic note. Wrong contents of the first electronic note can be manifested as an error in the amount in the first electronic note. For example, when the merchant and the consumer trade, the consumer pays 10 yuan, but the amount on the first electronic note generated by the merchant is 5 yuan. If the amount on the first electronic note does not match the actual transaction amount, then the amount in the first electronic note is wrong. An error in the content of the first electronic note may also appear as an error in the title or tax rate of the first electronic note. The embodiment of the present invention does not specifically limit the error content in the first electronic note.

Since the content of the first electronic note is wrong, there are many situations. In some embodiments, the electronic note processing request can also carry the modified content. The modified content is the modified content on the first electronic note, which can be the amount or header or tax rate, etc., so that the second node device can generate correct electronic bills according to the target content.

The second node device may receive the electronic bill processing request in any of the following manners 1-2.

Method 1. The transaction-related operation of the merchant on the second node device triggers an electronic bill processing request, 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 offline, and the consumer requests the merchant to process the first electronic bill. Then, when the consumer and After the merchant communication 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. Wherein, the billing button can be a real button on the second node device for triggering an electronic bill processing request, or a virtual button on the billing interface of the second node device. Of course, the billing interface can also be selected by the processing type button, after the merchant selects the button according to the processing type to determine the processing type, enter the target content in the input box corresponding to the target content, and finally click the billing button to trigger the electronic bill processing request, so that the second node device receives the electronic bill processing request , the embodiment of the present invention does not specifically limit the billing button and the processing type selection button.

Mode 2. The second node device receives the electronic bill processing request sent by the third node device.

When the content of the first electronic bill is incorrect, or the transaction corresponding to the first electronic bill is cancelled, the consumer can trigger the third node device to send the electronic bill to the second node device through the billing button on the third node device. request, and then the second node device may receive the electronic bill processing request. Wherein, the billing button on the third node device is the same as the above-mentioned billing button on the second node device, and the embodiment of the present invention does not describe the billing button on the third node device in detail.

202. The second node device queries the billing record according to the bill identifier of the first electronic bill.

The billing record is used to record the electronic bills corresponding to the transaction conducted by the merchant. 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 checks whether there is a record of the first electronic bill stored in the billing record to verify 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. If the record corresponding to the first electronic note is stored on the record, it means that the first electronic note is an electronic note generated by the merchant through the second node device, then the second node device can continue the subsequent processing of the first electronic note , when there is no record corresponding to the first electronic bill stored in the billing record, it means that the first electronic bill is not an electronic bill generated by the merchant through the second node device, and the second node device does not need to process the first electronic bill .

203. When the processing type is a voided note, if the billing record stores a record corresponding to the first electronic note, the second node device obtains the key of the supervision node device.

The record corresponding to the first electronic bill is stored in the billing record, which may be expressed as storing the bill identifier carried by the electronic bill processing request in the billing record, or in the form of storing the electronic bill processing request in the billing record The first electronic note indicated by the note ID of .

The keys of the supervisory node device include a first key and a second key, wherein the first key is used to provide permission to send bills, and the second key is used to provide permission to transfer bills.

The second node device may obtain the first key of the supervision node device by sending a first key acquisition request to the supervision node device. In a possible implementation, the second node device obtains the The first key can be realized through the process shown in the following steps 20311-20314.

Step 20311, the second node device sends a first key acquisition request to the supervisory node device, and the first key acquisition request is used to acquire the first key of the supervisory node device.

The first key acquisition request may carry the node identification of the second node device and the identification of the first key, the identification of the first key is used to indicate the first key, and the first key is used to enable sending the ticket to the second node device. The authority of an address, where 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 the public key or address of the second node device, so that the supervisory node device can verify the first key acquisition request.

Step 20312. After receiving the first key acquisition request, the supervisory node device verifies the node identifier in the first key acquisition request.

When the blockchain system is initialized, the supervisory node device will store the node identifiers of each second node device, so that the supervisory node device can verify the obtained first key acquisition request. The supervisory node device may verify the node identifier in the first key acquisition request by querying the node identifiers of all second node devices stored in the supervisory node device. In a possible implementation, when the supervisory node device finds the node ID in the first key acquisition request from the stored node IDs of all second node devices, the node ID passes the verification; otherwise, the Node ID does not pass validation. Then, when the node identifier in the first key acquisition request passes the verification, the first key acquisition request passes the verification.

Step 20313, when the node identifier in the first key acquisition request passes the verification, the supervisory node device sends the first key of the supervisory node device to the second node device.

Step 20314, the second node device receives the first key of the supervision node device sent by the supervision node device.

The second node device may obtain the second key of the supervision node device by sending a second key acquisition request to the supervision node device. In a possible implementation, the second node device obtains the The second key can be realized through the process shown in the following steps 20321-20324.

Step 20321, the second node device sends a second key acquisition request to the supervisory node device, and the second key acquisition request is used to acquire the second key of the supervisory node device.

The second key acquisition request carries the node identifier of the second node device and the identifier of the second key, where the identifier of the second key is used to indicate the second key.

Step 20322. After receiving the second key acquisition request, the supervisory node device verifies the node identifier in the second key acquisition request.

The process of the supervisory node device verifying the node ID in step 20322 is the same as the process of the supervisory node device verifying the node ID in step 20312, and this step 20322 is not described in detail in this embodiment of the present invention.

Step 20323, when the node identifier in the second key acquisition request passes the verification, the supervisory node device sends the second key of the supervisory node device to the second node device.

Step 20324, the second node device receives the second key of the supervision node device sent by the supervision node device.

It should be noted that, in some embodiments, only the second node device that stores 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, and also 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, then, when receiving the first key acquisition request Or after the second key acquisition request, the supervisory node device may not verify the node identification in the first key acquisition request or the second key acquisition request, but directly send its own first key to the sending second node device. key or the second key, so as to improve the efficiency of the second node device in obtaining the first key or the second key.

It should be noted that, when the processing type is to modify a note, if the record corresponding to the first electronic note is stored in the billing record, the second node device will check the content of the sub-record corresponding to the first electronic note in the transaction record One-to-one comparison with the content of the first electronic note, when the content of the sub-record corresponding to the first electronic note in the transaction record does not match the corresponding content in the first electronic note, the second node device will obtain the supervision node The key for the device.

Transaction records are used to store the transactions reached by merchants and consumers. Each transaction corresponds to a sub-record in the transaction record, that is, each sub-record in the transaction record is used to store the transaction status of a transaction, and the transaction status may include the bill identification of the electronic bill and the transaction amount, time, goods, invoice title, tax rate, etc., and the embodiment of the present invention does not specifically limit the transaction situation.

When the content of the sub-record corresponding to the first electronic note in the transaction record does not match the corresponding content in the first electronic note, it means that the content in the first electronic note is wrong, for example, the amount in the first electronic note is 5 , the amount in the sub-record corresponding to the first electronic note is 10, then. The amount in the first e-receipt is incorrect.

The second node device can also directly compare the target content in the electronic note processing request with the target content in the sub-record corresponding to the first electronic note in the transaction record. When the target content in the sub-record corresponding to the ticket does not match, the second node device obtains the key of the supervisory node device.

Billing records and transaction records can be stored in the memory of the second node device, or in other storage devices, such as mobile hard drives, or in the cloud. The embodiment of the present invention does not specifically limit the storage locations and recording methods of the billing records and transaction records.

It should be noted that the process shown in steps 202-203 is a process for the second node device to further verify the electronic bill processing request and obtain the key of the supervisory node device, that is, when the billing record stores the When any content in the record corresponding to the first electronic note or the sub-record corresponding to the first electronic note does not match the corresponding content in the first electronic note, the electronic note processing request passes the verification, and the second node device obtains the supervision node Otherwise, the electronic bill processing request fails to pass the verification, and the second node device cannot obtain the key of the supervisory node device.

Then, through steps 202 and 203, it is possible to further verify whether the electronic receipt processing request is correct, avoid processing wrong electronic receipt processing requests, and further reduce the error rate of the second node device in processing electronic receipt processing requests.

204. The second node device generates a second electronic note in the blockchain system based on the first electronic note indicated by the note identifier and the processing type.

When the processing type is to modify a note, and the modification content carried in the electronic note processing request is the amount, at this time, the purpose of modifying the note is to modify the amount on the first electronic note, and the amount on the first electronic note only needs to be partially reversed. Yes, therefore, the amount in the second electronic note generated by the second node device is the negative value of the difference between the amount in the first electronic note and the target content, and the other content in the second electronic note is the same as the first Other contents of the electronic notes are the same.

When the processing type is to modify the note, and the modification content carried in the electronic note processing request is not the amount, at this time, the purpose of modifying the note is to modify other content on the first electronic note, and all the content on the first electronic note needs to be All reversals, so the amount in the second electronic note generated by the second node device is the negative value of the amount in the first electronic note, and other contents in the second electronic note are different from other contents in the first electronic note All consistent.

When the processing type is voided note, the voided note is to invalidate the first electronic note, and all the content on the first electronic note needs to be reversed. Therefore, the amount in the second electronic note is equal to the amount in the first electronic note. The negative value of the amount, the other contents of the second electronic note are consistent with the other contents of the first electronic note.

205. The second node device sends the second electronic note to the first address in the blockchain system based on the key of the supervision node device in the blockchain system, and the first address is based on the key of the supervision node device in the blockchain system. The address of multi-signature between the device and the ticket object of the electronic ticket processing request.

Wherein, the first address is a virtual address in the blockchain system, and is used to store the second electronic note generated by the second node device, the invalidated first electronic note, and the modified third electronic note. The bill object of the electronic bill processing request is the consumer who conducts the transaction corresponding to the first electronic bill with the merchant.

The multi-signature address based on the supervisory node device and the note object of the electronic bill processing request can be expressed as the first address and the key of the supervisory node device, the key of the third node device, and the key of the second node device have an association relationship. The owner of the key associated with the multi-signature address has both the authority to access the multi-signature address and the authority to transfer electronic notes within the multi-signature address. When it is necessary to transfer electronic bills in the multi-signature address, at least one key associated with the multi-signature address is required to transfer the electronic bills in the multi-signature address.

Since different keys of the supervisory node device can provide different permissions, and the first key is used to provide the authority to send bills, the second node device needs to obtain the supervisory node device’s The first key, the second node device can obtain the first key of the supervisory node device through the process shown in steps 20311-20314.

206. The second node device transfers the first electronic note stored in the second address to the first address based on the key of the supervisory node device in the blockchain system, and transfers the first electronic note stored in the second address to the first address that does not carry a mark. A first mark is added to the electronic note, and the note identification of the second electronic note is added to the first electronic note stored in the first address, and the first mark is used to indicate that the first electronic note is invalid.

The second address can be a virtual address in the blockchain system, and is used to store multiple electronic bills, each electronic bill is associated with a consumer account, and an electronic bill can be represented as an electronic bill in the corresponding consumer account. The electronic version of the blue letter invoice. Certainly, the second address may also be the address of the third node device that sends the electronic bill processing request, and this embodiment of the present invention does not specifically limit the second address.

Since different keys of the supervisory node device can provide different permissions, and the second key is used to provide the authority to transfer bills, the second node device needs to obtain the supervisory node device’s ID before transferring the first electronic bill to the first address. For the second key, the second node device can obtain the first key of the supervisory node device through the process shown in steps 20322-20324.

It should be noted that the second node device has the right to transfer the first electronic note to the first address only after obtaining the second key of the supervisory node device, and the second node device obtains the second key of the supervisory node device. The step of obtaining the key may be between step 205 and step 206, or may be before step 205. This embodiment of the present invention does not specifically limit the step of obtaining the second key of the supervisory node device and the execution order of step 205.

After transferring the first electronic note to the first address, the second node device adds the first mark to the first electronic note that does not carry the mark, and the second node device can add the first mark to the target field of the first electronic note. A mark, the first mark may be any character string, and this embodiment of the present invention does not specifically limit the first mark. The target field may be any free field in the first electronic note, or may be a newly added field in the first electronic note, and the embodiment of the present invention does not specifically limit the target field.

Then, when the first electronic note is marked with the first mark, it means that the first electronic note has been invalidated.

The ticket identification of the second electronic note is the code, number and verification code of the second electronic note, and of course it can also be other information indicating the second electronic note. The embodiment of the present invention does not specifically limit the second identification.

The second node device can add the note identification of the second electronic note in the remarks information field in the first electronic note, and of course also add the note identification of the second electronic note in other fields. The field for adding the note identifier of the second electronic note is not specifically limited. By adding the note identification of the second electronic note in the first electronic note, the first electronic note can be made to correspond to the second electronic note, so that it can be verified later.

It should be noted that, in this step 206, the second node device transfers the first electronic note stored in the second address to the first address based on the key of the supervisory node device in the blockchain system, and sends The process of adding the first mark to the first electronic note that does not carry a mark, that is, the process of adding the first mark to the first electronic note stored in the first address by the second node device.

207. When the processing type is ticket modification, the second node device generates a third electronic ticket according to the modification content carried in the electronic ticket processing request.

The second electronic device may replace the target content on the first electronic note with the modification content carried in the electronic note processing request to obtain a third electronic note, the target content is the wrong content of the first electronic note, and the third Other content in the note is consistent with other content in the first electronic note.

208. The second node device sends the third electronic note to the first address based on the key of the supervision node device in the blockchain system.

Before the second node device sends the third note to the first address, the second node device also needs to obtain the first key of the supervisory node device again, so that the second node device can the first key, and send the third electronic note to the first address.

It should be noted that the second node device will execute steps 207-208 only when the processing type is revising bill reversal, and the second node device will not execute steps 207-208 when the processing type is voiding bills .

209. The second node device adds the note identification of the first electronic note to the second electronic note stored in the first address, and outputs the second electronic note carrying the note identification of the first electronic note and The third electronic note.

The second node device may add the note identifier of the first electronic note in the field of the second electronic note for recording remark information, so as to add the note identifier of the first electronic note in the second electronic note, and then establish the second electronic note. The corresponding relationship between the second electronic note and the first electronic note for future verification.

The first node device may output the second electronic note and the third electronic note by sending the second electronic note and the third electronic note to the second address storing the first electronic note.

When the second address is a virtual address, the second node device directly sends the second electronic note and the third electronic note to the location where the first electronic note is stored; when the second address is the address of the third node device , the second node device sends the second electronic note and the third electronic note to the third node device.

When the second address has access authority, the second node device can send the second electronic note and the third electronic note to the second address only after obtaining the access authority, for example, the second address is consumed If the user sets the access authority, the second node device sends a bill issuance request to the second address, and the bill issuance request carries the second electronic bill and the third electronic bill. When the consumer refuses to accept the bill through the third node device When issuing a request, the second node device cannot send the second electronic bill and the third electronic bill to the second address. When the consumer receives the bill issuing request through the third node device, the second node The device may send the second electronic note and the third electronic note to the second address.

It should be noted that, when the processing type is a voided note, the second node device will not generate the third electronic note, and will not output the third electronic note. In addition, the first electronic note is invalidated, and the second node device generates a second electronic note for reversing the first electronic note, and generates a third electronic note, so that the second electronic note and the third electronic note can replace the first electronic note. Electronic bills, so as to realize the red punching of bills. In order to further illustrate the process of bill red flushing before reimbursement, refer to the flow chart of the method for bill red flushing before reimbursement as shown in FIG. 3 provided by the embodiment of the present invention. The process specifically includes the following steps 3.1-3.4.

Step 3.1. The consumer initiates a red charge to the billing company offline.

When the consumer initiates a red redemption of the first bill to the billing company offline, the billing company will know that it is necessary to redid the first electronic bill, which is equivalent to the second node device receiving the electronic bill sent by the third node device Ticket processing request.

Step 3.2. The invoicing enterprise invokes the first key of the tax authority through the second node device, and issues the second electronic bill to the (tax authority + consumer) multi-signature address.

Among them, the (tax authority + consumer) multi-signature address is the first address.

Step 3.3. The second node device invokes the second key of the tax authority, transfers the first electronic bill to the (tax authority + consumer) multi-signature address, and marks the first electronic bill with a red red status.

Wherein, the second node device marking the red mark on the first electronic note is equivalent to marking the first mark on the first electronic note.

Step 3.4, the second node device calls the first key of the tax authority, and reissues a new third electronic note to (tax authority + consumer) according to the processing type (modify the information in the first electronic note, or return the goods) The multi-signature address is used to implement re-issuance, and the second node device reuses the normal invoice interface to perform steps 202-209 when invoicing.

It should be noted that steps 3.2-3.4 are all executed in the blockchain system.

In order to further illustrate the red punching process of the present invention, refer to a schematic diagram of a logic design for red punching as shown in FIG. 4 provided by the embodiment of the present invention.

It can be seen from Figure 4 that the consumer communicates with the merchant offline. The consumer expresses the need to redact the blue invoice (the blue invoice is equivalent to the first electronic invoice), and the merchant opens the applet on the second node device or PC (personal computer, personal computer) management terminal, run a small program or PC management terminal to judge whether it is a return red charge (return red charge is equivalent to a voided bill), if it is a return red charge, open a small program or PC management end A red-letter invoice (the red-letter invoice is equivalent to the second electronic bill) is given to the consumer. The amount on the red-letter invoice is negative, and the number of the original blue-letter invoice (the original blue-letter invoice is equivalent to the first electronic bill) is noted. Mark red red on the blue invoice (the red red mark is equivalent to the first mark), and add the invoice number of the new red invoice in the remark (the invoice number is equivalent to the bill mark), and the consumer returns the goods to the merchant, and the merchant Return the money to the consumer. If it is not a red red charge for return, it means that the billing is wrong (wrong billing is equivalent to modifying the bill), which is manifested as wrong title, amount or tax rate on the blue invoice. Run the applet or PC management terminal to issue a red invoice to Consumers, the amount on the red invoice is negative, and note the number of the original blue invoice, mark the red mark on the original blue invoice, and the merchant directly inserts a correct blue invoice (the correct blue invoice is equivalent to The third electronic note) to the consumer's account, the original wrong blue letter invoice will no longer be displayed to the consumer.

In the method provided by the embodiment of the present invention, the generated second electronic note is sent to the first address through the processing type, the first key and the second key in the electronic note processing request, and the first electronic note is transferred to the second address. In the first address, the first electronic bill in the first address is invalidated, and the second electronic bill is output. Therefore, the process of processing electronic bills does not require consumers to go to the tax authority to issue relevant certificates, and does not require consumers to provide merchants with tax authorities. Relevant proofs reduce the process of consumer participation, so for consumers, the process of processing electronic bills is relatively simple, that is, the process of issuing red-letter invoices is too simple, so the process of processing electronic bills can be handled by the second node The equipment is completed independently, and consumers are not required to go to the tax authorities to issue relevant certificates, and consumers are not required to provide merchants with relevant certificates issued by the tax authorities, which reduces the process of consumer participation. For consumers, the process of processing electronic bills Relatively simple, that is to say, the process of issuing red-letter invoices is too simple. Moreover, the supervisory node device may not verify the node identification in the first key acquisition request and the second key acquisition request, but directly send its own first key and second key to the Obtain the efficiency of the first key and the second key, and by querying the billing records and consumption records, it is possible to further verify whether the electronic bill processing request is correct, avoid processing wrong electronic bill processing requests, and further reduce the cost of the second node device. Error rate in processing electronic bill processing requests. Moreover, by adding the note identifier of the second electronic note in the first electronic note, the first electronic note can be made to correspond to the second electronic note, so as to facilitate future verification. Moreover, the second node device may add the note identifier of the first electronic note in the field of the second electronic note for recording remark information, so as to add the note identification of the first electronic note in the second electronic note, and then can The corresponding relationship between the second electronic note and the first electronic note is established for future verification.

The electronic bill processing flow shown in Figure 2 is the electronic bill processing flow before reimbursement. In some embodiments, after the second node device reimburses the first electronic bill at the third node device, the first electronic bill needs to be invalidated or modification, the second node device also needs to process the first electronic note. In order to further illustrate the process of the second node device processing the first electronic note in this case, please refer to Figure 5, which is an example provided by the embodiment of the present invention A flow chart of a method for processing electronic bills, the process specifically includes the following steps.

501. The second node device receives an electronic receipt processing request, where the electronic receipt processing request carries the receipt identifier and processing type of the first electronic receipt.

It should be noted that when the first electronic bill has been reimbursed by the reimbursement company, only through the operation of the merchant can the second node device be triggered to receive the electronic bill processing request. The electronic bill processing request can carry the third mark, the first The three marks are used to indicate that the first electronic note has been reimbursed.

502. The second node device queries the billing record according to the bill identifier of the first electronic bill.

The process of this step 502 is the same as the process shown in step 202, and the embodiment of the present invention does not repeat the process of this step 502.

503. When the processing type is to modify a note, if the record corresponding to the first electronic note is stored in the billing record, the second node device compares the content of the sub-record corresponding to the first electronic note in the transaction record with the first The content of the electronic note is compared one by one. When the content of the sub-record corresponding to the first electronic note in the transaction record does not match the corresponding content in the first electronic note, the second node device obtains the password of the supervisory node device. key.

The second node device can also directly compare the target content in the electronic note processing request with the target content in the sub-record corresponding to the first electronic note in the transaction record. When the target content in the sub-record corresponding to the ticket does not match, the second node device obtains the key of the supervisory node device.

It should be noted that, when the processing type is a voided note, if a record corresponding to the first electronic note is stored in the billing record, the second node device obtains the key of the supervisory node device.

The process shown in steps 502-503 is a process for the second node device to further verify the electronic bill processing request and obtain the key of the supervisory node device, that is, when the billing record stores the information corresponding to the first electronic bill When any content in the record or the sub-record corresponding to the first electronic note does not match the corresponding content in the first electronic note, the electronic note processing request passes the verification, and the second node device obtains the key of the supervisory node device, Otherwise, the electronic bill processing request does not pass the verification, and the second node device cannot obtain the key of the supervisory node device.

Through steps 502 and 503, it can be further verified whether the electronic receipt processing request is correct, and processing of wrong electronic receipt processing request can be avoided, thereby reducing the error rate of the second node device in processing the electronic receipt processing request.

504. When the electronic bill processing request carries a third flag, the second node device sends a status flag request to the first node device, where the status flag request is used to indicate bill transfer and flagging, and the third flag is used to indicate The first electronic note has been reimbursed.

When the second node device receives the electronic bill processing request, it will detect the content requested by the electronic bill processor, and when the third mark is detected in the electronic bill processing request, the second node device will Execute this step 504 .
