Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Embodiments of the present application relate to blockchains and blockchain networks. The Block Chain (Block Chain) is a novel application mode of computer technologies such as distributed data storage, point-to-point (Peer to Peer, P2P) transmission, consensus mechanism, encryption algorithm and the like. The block chain is a set of decentralized basic framework with distributed storage characteristics, in particular to a data structure formed by data blocks in a linked list-like mode according to a time sequence, which can safely store data which are in a sequential relation and can be verified in a system, and can ensure that the data cannot be tampered and forged in a cryptographic mode.

The blockchain network includes a plurality of blockchain node devices, and the blockchains are stored in respective blockchain node devices of the blockchain network. For example, the blockchain network may include blockchain link node devices such as a management node device, a first audit node device, a second audit node device, and the like. The device of the block chain nodes in the block chain network can be a client, a server, a terminal, and the like. The terminal may be a mobile terminal, a Personal Computer (PC) terminal, or a laptop Computer (Tablet PC) terminal, etc.

In the transaction auditing scheme, after a management node device in the block chain network receives a target to-be-processed transaction sent by user equipment, the management node device audits the target to-be-processed transaction, and if the target to-be-processed transaction is approved, the management node device executes a first transaction operation corresponding to the target to-be-processed transaction. The management node equipment in the block chain network audits the target to-be-processed transaction, and other block chain node equipment in the block chain network can see the auditing process of the management node equipment on the target to-be-processed transaction, so that the transaction auditing process is transparent, and the reliability of the transaction auditing result is improved.

The user equipment is a node device outside the blockchain network, and the user equipment may be a client, a server, a terminal, and the like. The terminal may be a mobile terminal, a Personal Computer (PC) terminal, or a laptop Computer (Tablet PC) terminal, etc.

The target pending transaction includes a transaction request and audit information. The transaction request may be used to request the management node device to audit the target to-be-processed transaction according to the audit information, and to request the management node device to execute a first transaction operation corresponding to the target to-be-processed transaction after the audit is passed. The audit information may include registration information, warning policy change notification, or warning policy enforcement information. The registration information may be used to verify the identity of the user equipment. The warning policy change notification may be used to audit the changed warning policy. The early warning policy execution information may be used to audit an early warning policy execution event of the user equipment.

Based on the above description, please refer to fig. 1, where fig. 1 is a schematic structural diagram of a transaction auditing system according to an embodiment of the present application. As shown in fig. 1, the transaction auditing system includes a management node device 101, a first audit node device 102, a second audit node device 103, and a user device 104. The management node device 101, the first audit node device 102, and the second audit node device 103 are block link node devices in a block chain network, where the block chain network includes the management node device 101, the first audit node device 102, and the second audit node device 103 only for example, and the block chain network may include a plurality of management node devices 101, a plurality of first audit node devices 102, and a plurality of second audit node devices 103. The user equipment 104 is a node device outside the blockchain network.

In a transaction auditing system composed of a management node device 101, a first audit node device 102, a second audit node device 103 and a user device 104, the user device 104 sends a target to-be-processed transaction to the management node device 101, after the management node device 101 receives the target to-be-processed transaction, the management node device 101 audits the target to-be-processed transaction according to auditing information included in the target to-be-processed transaction, and if the target to-be-processed transaction is approved, the management node device 101 responds to a transaction request included in the target to-be-processed transaction and executes a first transaction operation corresponding to the target to-be-processed transaction.

In an implementation manner, the auditing information is different, and the auditing manner of the management node device 101 for auditing the target to-be-processed transaction is also different. If the audit information includes the registration information, the management node device 101 may directly audit the registration information. If the audit information includes the warning policy change notification or the warning policy execution information, the management node device 101 may request the first audit node device 102 or the second audit node device 103 to perform assistance audit on the target to-be-processed transaction, where an audit level of the second audit node device 103 is higher than an audit level of the first audit node device 102, and an audit level of the first audit node device 102 is higher than an audit level of the management node device 101.

In one implementation, the audit information may include registration information. The management node device 101 may check validity of the registration information, and if the validity check of the registration information passes, the management node device 101 determines that the target to-be-processed transaction is approved. In order to ensure the reliability of the audit result, the management node device 101 may assist in the verification of the validity of the registration information by means of an information system (e.g., an industrial and commercial system, a public security system, etc.) associated with the management node device 101.

In one implementation, the audit information may include an early warning policy change notification. The management node device 101 may change the original early warning policy of the user device 104 according to the early warning policy change notification, and obtain the changed early warning policy. Since the management node device 101 does not reach the audit level at which the changed early warning policy can be verified, and the management node device 101 cannot verify the changed early warning policy, the management node device 101 may send the changed early warning policy to the first audit node device 102. The first audit node device 102 verifies the changed early warning policy to obtain a verification result, the first audit node device 102 sends the verification result to the management node device 101, if the verification result is that verification is passed, the management node device 101 can update the original policy information of the user device 104 to the changed early warning policy, and the changed early warning policy takes effect.

In one implementation, the audit information may include early warning policy enforcement information. The management node device 101 may respond to the early warning policy execution event of the user device 104 indicated by the early warning policy execution information, and generate a second transaction operation to be executed on the user device 104, where the early warning policy execution event may be used to indicate an early warning policy execution condition of the user device 104. Since the management node device 101 does not reach the auditing level at which the second transaction operation can be verified, and the management node device 101 cannot verify the second transaction operation, the management node device 101 may send the second transaction operation to the second audit node device 103. The second audit node device 103 checks the second transaction operation to obtain a check result, the second audit node device 103 sends the check result to the management node device 101, and if the check result is that the check is passed, the management node device 101 may execute the second transaction operation on the user device 104.

In an implementation manner, in order to reduce the audit load of the second audit node device 103 and ensure that the second transaction operation to be executed by the user device 104 and generated by the management node device 101 is accurate, before the management node device 101 sends the second transaction operation to the second audit node device 103, the management node device 101 may send the second transaction operation to the first audit node device 102, the first audit node device 102 performs a prior check on the second transaction operation to obtain a check result, the first audit node device 102 sends the check result to the management node device 101, if the check result is a pass check, the management node device 101 sends the second transaction operation to the second audit node device 103, and the second audit node device 103 performs a further check on the second transaction operation.

It can be understood that the transaction auditing system described in the embodiment of the present application is for more clearly illustrating the technical solutions of the embodiment of the present application, and does not constitute a limitation to the technical solutions provided in the embodiment of the present application, and as a person having ordinary skill in the art knows that along with the evolution of the system architecture and the appearance of new business scenarios, the technical solutions provided in the embodiment of the present application are also applicable to similar technical problems.

Taking a transaction auditing scene of a tax bureau as an example, the tax bureau is provided with three transaction auditing posts, namely a comprehensive business post, a business auditing post and a business auditing and approving post, each post is provided with a plurality of posts, a working network of the tax bureau is the block chain network, and the tax bureau allocates a block chain account number which can uniquely identify the post for each post. The management node device 101 is a block chain link point device for the integrated service post to log in by using a block chain account of the integrated service post, the first audit node device 102 is a block chain link point device for the service audit post to log in by using the block chain account of the service audit post, and the second audit node device 103 is a block chain link point device for the service audit post to log in by using the block chain account of the service audit post. In the auditing system of the tax bureau, the auditing grade of the business auditing post is higher than that of the business auditing post, and the auditing grade of the business auditing post is higher than that of the comprehensive business post. The user device 104 is a node device that a user requesting the tax authority to audit transactions logs in with a user account, which may uniquely identify the user.

For example, the enterprise sends a target pending transaction to the tax authority, the target pending transaction includes a transaction request and registration information of the enterprise, the transaction request is used for requesting to audit the registration information from the tax authority and requesting to issue an electronic invoice, and the registration information may include, but is not limited to, an invoice-specific chapter of the enterprise, a taxpayer identification number of the enterprise, and a registration serial number of the enterprise. And after the comprehensive service post receives the target to-be-processed transaction, verifying the legality of the registration information of the enterprise. The integrated service post can request the public security system to assist in verifying the special invoice seal and request the industrial and commercial system to assist in verifying the taxpayer identification number and the registration sequence number. If the validity of the registration information is verified, the comprehensive management post can respond to the transaction request to issue an electronic invoice for the enterprise.

For another example, the enterprise sends a target to-be-processed transaction to the tax bureau, where the target to-be-processed transaction includes a transaction request and an early warning policy change notification, and the transaction request is used to request the tax bureau to change the early warning policy. Referring to fig. 2, a process of auditing a target to-be-processed transaction by the tax administration according to the warning policy change notification is shown, and fig. 2 is a schematic flow diagram of a warning policy auditing scheme provided in an embodiment of the present application. And after receiving the target to-be-processed transaction, the comprehensive business post carries out change operation on the original early warning strategy of the enterprise according to the early warning strategy change notice to obtain the changed early warning strategy. The change operation may include, but is not limited to, an add operation, an edit operation, a delete operation. The comprehensive service post does not reach the auditing grade capable of verifying the changed early warning strategy, and the comprehensive service post cannot verify the changed early warning strategy, so that the comprehensive service post sends the changed early warning strategy to the service auditing post, the service auditing post verifies the changed early warning strategy, if the service auditing post passes the verification, the comprehensive service post can update the original early warning strategy of an enterprise into the changed early warning strategy, and the changed early warning strategy takes effect.

For example, the enterprise sends a target to-be-processed transaction to the tax bureau, where the target to-be-processed transaction includes a transaction request and early warning policy execution information, the transaction request is used to request the tax bureau to review the early warning policy execution information, and the early warning policy execution information indicates the early warning policy execution condition of the enterprise (e.g., whether the enterprise declares tax payment within a specified time limit, whether the enterprise declares tax registration, change or logout registration within a specified time limit, whether the enterprise reports all bank accounts of the enterprise to the tax bureau according to the specification, or whether an early warning value of the enterprise exceeds an early warning threshold, etc.). After the comprehensive service post receives the target to-be-processed transaction, the process of auditing the target to-be-processed transaction according to the early warning strategy execution information is as follows: if the early warning strategy execution information indicates that the enterprise does not declare tax payment within the specified time limit, the integrated service post generates the operation of stopping invoicing to be executed by the enterprise; the comprehensive service post cannot verify the operation of stopping invoicing, so that the comprehensive service post sends the operation of stopping invoicing to the service auditing post, and the service auditing post verifies the operation of stopping invoicing; if the service auditing post passes the verification, the comprehensive service post sends the operation of stopping invoicing to a service auditing post, and the service auditing post verifies the operation of stopping invoicing again; if the business approval post passes the verification, the comprehensive business post stops issuing the electronic invoice to the enterprise, and the enterprise cannot continue issuing the electronic invoice.

In the embodiment of the application, each blockchain node device in the blockchain network commonly witnesses the auditing process of the management node device on the target to-be-processed transaction, so that the auditing process of the management node device on the target to-be-processed transaction is transparent, the reliability of the transaction auditing result is improved, and the transaction operation corresponding to the target to-be-processed transaction executed by the management node device also has higher reliability. In addition, the target to-be-processed transaction comprises different auditing information, the auditing modes of the management node device for the target to-be-processed transaction are different, and different auditing information corresponds to different auditing modes, so that the auditing process of the management node device for the target to-be-processed transaction is flexible and various, and the reliability of the transaction auditing result is improved. And multi-stage auditing is also involved in the process of auditing the target to-be-processed transaction, so that the auditing load of auditing equipment with different auditing grades can be reduced on one hand, and the reliability of the auditing result is further improved on the other hand.

The management node device may store the received multiple to-be-processed transactions in a transaction list of the blockchain network, where the transaction list of the blockchain network stores the received to-be-processed transactions in a form of a queue, and the to-be-processed transactions stored in the transaction list first may be audited by the management node device, and then the to-be-processed transactions stored in the transaction list may be audited subsequently by the management node device. The management node device may obtain, from the transaction list, a target to-be-processed transaction sent by the user device, where the target to-be-processed transaction is any one of the to-be-processed transactions in the transaction list.

In one implementation, after the management node device obtains a target to-be-processed transaction sent by the user device from the transaction list, the management node device may send a transaction getting notification to other block link node devices in the block chain network, where the transaction getting notification may include a transaction identifier of the target to-be-processed transaction, and the transaction getting notification may be used to indicate that the target to-be-processed transaction corresponding to the transaction identifier is in a processed state, and other block chain node devices in the block chain network cannot audit the target to-be-processed transaction.

In one implementation, the target pending transaction may include a transaction request and audit information. The audit information may include registration information, warning policy change notification, or warning policy enforcement information.

Step S302: and the management node equipment audits the target to-be-processed transaction according to the audit information.

Step S303: and if the target to-be-processed transaction is approved, the management node equipment responds to the transaction request to execute a first transaction operation corresponding to the target to-be-processed transaction.

In an implementation manner, the audit information may include registration information, and if the management node device passes the audit on the target to-be-processed transaction according to the registration information, the management node device may respond to the transaction request and execute a first transaction operation corresponding to the target to-be-processed transaction, and a process of executing the first transaction operation corresponding to the target to-be-processed transaction by the management node device may be described in detail in step S404 in the embodiment shown in fig. 4.

Taking an electronic invoice auditing scene of the tax bureau as an example, an enterprise sends a target to-be-processed transaction to a comprehensive business post of the tax bureau. The target pending transaction comprises a transaction request and registration information of the enterprise, wherein the transaction request is used for requesting to audit the registration information from the tax bureau and requesting to make an electronic invoice according to the registration information, the registration information comprises an enterprise code and first identification information of the enterprise, the enterprise code can uniquely identify the enterprise, and the first identification information of the enterprise can comprise but is not limited to an invoice special chapter of the enterprise, a taxpayer identification number of the enterprise and a registration serial number of the enterprise. And after the integrated service post receives the target to-be-processed transaction, the integrated service post checks the legality of the registration information of the enterprise.

The validity check process of the registration information of the enterprise by the integrated service post is as follows: the comprehensive business post can acquire the special invoice seal corresponding to the enterprise code from the public security system according to the enterprise code, and acquire the taxpayer identification number corresponding to the enterprise code and the registration serial number corresponding to the enterprise code from the industrial and commercial system; the management node equipment compares the received special invoice seal in the target to-be-processed transaction with the special invoice seal obtained from the public security system, compares the received taxpayer identification number in the target to-be-processed transaction with the taxpayer identification number obtained from the industrial and commercial system, and compares the received registration sequence number in the target to-be-processed transaction with the registration sequence number obtained from the industrial and commercial system; and if the received invoice special seal is the same as the invoice special seal obtained from the public security system, the received taxpayer identification number is the same as the taxpayer identification number obtained from the industrial and commercial system, and the received registration sequence number is the same as the registration sequence number obtained from the industrial and commercial system, the management node equipment determines that the validity check of the registration information is passed.
