Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Fig. 1 shows an implementation flow of a service billing method based on a block chain according to an embodiment of the present invention, which is detailed as follows:
in S101, performing serial sequential splitting on received complex service information to obtain a plurality of service sub information, where the complex service information includes a start identifier and an end identifier, the start identifier is used to indicate the service sub information located at the head, and the end identifier is used to indicate the service sub information located at the tail.
In the embodiment of the present invention, the terminal device first obtains complex service information to be billed, which is generated by an upstream system, where the complex service information includes a plurality of service sub-information, and for convenience of description, the complex service information is described as transfer transaction information, but this does not limit the embodiment of the present invention. In order to standardize the generation and detection mechanism of the complex service information, in the embodiment of the present invention, a complete complex service information is set to include a start identifier and an end identifier, where the start identifier is used to indicate the service sub-information located at the head (the service sub-information located at the head includes the start identifier), and the end identifier is used to indicate the service sub-information located at the end (the service sub-information located at the end includes the end identifier). The specific content of the start identifier and the end identifier can be set by self according to the actual situation. In addition, since the terminal device may receive a plurality of different complex service information at the same time, the upstream system may be configured to randomly generate a Start identifier and an end identifier according to different services, for example, in the random generation process, the Start identifier generated by the upstream system is "Start-Num start ", where Num start The Start is used for indicating that the identifier is a Start identifier; the End mark matched with the End mark is' End-Num start ", end is used to indicate that the tag is an End tag. At the same time, set the terminal device according toThe service number in the Start identifier identifies different complex service information, and for example, after receiving the information containing the Start identifier "Start-1" and the information containing the Start identifier "Start-2", it can be identified that the two pieces of information do not belong to the same complex service information.
A complete complex service message contains multiple service sub-messages, for example, the complex service message is "Account A Account to Account B Transfer 100 Yuan (including Start identifier), account B Account to Account C If the transfer is 500 yuan (including the end identifier), the service sub-information is' Account A Account to Account B Transfer 100 Yuan "and" Account B Account to Account C Transfer 500 yuan ". After receiving the complete complex service information, the terminal equipment carries out serial sequence splitting on the complex service information, wherein the splitting basis is a time basis or an initiator basis, and when the time basis aims at a scene containing a plurality of time points in the complex service information, and the serial sequence splitting is carried out according to the time basis, service sub-information corresponding to the time points is split according to the sequence of the time points in the complex service information from front to back; when the serial sequence splitting is carried out according to the initiator, the service sub-information corresponding to the initiator is sequentially split according to the sequence of each initiator from front to back in the complex service information, for example, for the Account A Account to Account B Transfer 100 Yuan, account B Account to Account C For complex service information of transfer 500 yuan', the first initiator is Account Account A The second initiator is Account Account B Therefore, the business sub-information corresponding to the first initiator can be divided into' Account A Account to Account B Transfer 100 Yuan, the business sub-information corresponding to the second initiator is' Account B Account to Account C Transfer 500 yuan ". Generally speaking, since the service implementation (such as the transfer) is sequential, the sequence of the service sub-information and the service sub-information split according to the time base and the initiator base is generally the same according to the actual application fieldThe scenes may be split serially in order using the above or other basis. It should be noted that if other service sub-information exists between the service sub-information containing the start identifier and the service sub-information containing the end identifier, other service sub-information may be set to contain the same start identifier for easy identification, for example, one complex service information may be "Account information A Account to Account B Transfer 100 Yuan (containing Start identifier Start-1), account B Account to Account C 500 Yuan transfer (containing Start-1) Account Account C Account to Account D Transfer 400 Yuan (containing the End identifier End-1) ".
Optionally, if the service sub information including the same start identifier is not received and the service sub information including the end identifier corresponding to the start identifier is not received within the freezing duration after the service sub information including the start identifier is received, the service sub information including the start identifier is placed in the freezing database. In the embodiment of the present invention, a freezing duration (for example, 30 minutes) may be set in the terminal device, and if the service sub-information including the same start identifier is not received in the freezing duration after the service sub-information including the start identifier is received, and the service sub-information including the end identifier corresponding to the start identifier is not received, it is verified that the corresponding service is in a stalled state, so that the service sub-information including the start identifier local to the terminal device is stored in the freezing database, and is not processed for a while, so that the stalled service is prevented from occupying processing resources of the terminal device. And if the service sub-information containing the same start identifier or the service sub-information containing the corresponding end identifier is received subsequently, the matched service sub-information can be searched from the freezing database, and the processing is continued.
In S102, submitting the plurality of service sub-information to an endorsement node set, where an endorsement node in the endorsement node set is configured to perform simulated transaction verification on the plurality of service sub-information one by one, and return an endorsement result that the endorsement is successful after the simulated transaction verification is successful.
And submitting the plurality of business sub-information to an endorsement node set in the block chain, wherein the endorsement node set comprises one or more endorsement nodes, and the endorsement nodes are used for performing simulated transaction verification on the plurality of business sub-information one by one. In a blockchain, a node (peer) refers to a communication entity of the blockchain for maintaining a copy of the blockchain ledger, the node belongs to a logical concept, and a plurality of nodes of different types can run on the same physical machine. In the embodiment of the invention, a designated endorsement node can be performed in advance in a plurality of nodes of the blockchain, and a simulated transaction verification function is deployed on the endorsement node, wherein the simulated transaction verification function is specifically that after a plurality of business sub-information are received, simulated transaction verification is performed one by one in a copy of the blockchain ledger according to the plurality of business sub-information (the verification process is only copy verification, namely, the transaction performed in the verification process is not real transaction and cannot affect data in the blockchain), and after the simulated transaction verification of all the business sub-information is successful, an endorsement result with successful endorsement is returned.
For example, the endorsement node receives the first service sub-information as "Account A Account to Account B Transfer 100 Yuan and the second service sub-information is Account B Account to Account C After transferring 500 yuan, firstly performing simulated transaction verification according to the first business sub-information, and specifically verifying Account in the copy of the block chain Account A Whether the Account balance is greater than or equal to 100 yuan, if the Account A If the account balance is greater than or equal to 100 yuan, the copy of the block chain account book can support the transaction of the first business sub-information, and the endorsement node continues to verify the second business sub-information; if Account Account A If the account balance is less than 100 yuan, the endorsement result of the endorsement failure is directly returned. The endorsement node verifies the second business sub-information on the basis that the first business sub-information simulates the completion of the transaction, namely, the Account is used for verifying the second business sub-information B Account received A The Account is judged according to the 100-element Account transfer and the copy of the block chain Account book B Whether the Account balance is greater than or equal to 500 yuan, if the Account is Account B Account balance greater than or equal toIf the number is equal to 500 yuan, the transaction verification is simulated to be successful, and the endorsement result of the endorsement success is returned; and if the account balance is less than 500 yuan, simulating transaction verification failure and returning an endorsement result of the endorsement failure.
Optionally, a preset intelligent contract is deployed to the endorsement node, the endorsement node splits the complex service information into a plurality of service sub-information, and the plurality of service sub-information are subjected to simulated transaction verification one by one. In the embodiment of the invention, the process of serial sequence splitting of complex service information can be integrated into the endorsement node, specifically, an intelligent contract is compiled based on the functional logic of serial sequence splitting and the functional logic of simulated transaction verification, and the intelligent contract is deployed to the endorsement node. After deployment is completed, when the terminal equipment receives the complex service information, the complex service information is directly submitted to the endorsement node in the endorsement node set, and the endorsement node completes splitting of the complex service information and verification of the simulated transaction of the split plurality of service sub-information, so that the workload of the terminal equipment is reduced, and the processing efficiency of the terminal equipment on the complex service information is improved. It is worth mentioning that the terminal device can uniformly submit the existing complex service information to the endorsement node set for performing the simulated transaction verification when the received complex service information reaches the preset number or the preset data volume, so as to prevent the communication resource loss caused by frequent submission.
In S103, if the received endorsement results are successful endorsement and the endorsement node returning the endorsement result satisfies a preset condition, submitting the plurality of service sub-information including the endorsement result to a preset consensus node, where the consensus node is configured to perform billing in a block chain for the plurality of service sub-information including the endorsement result.
The terminal equipment acquires endorsement results returned by endorsement nodes in the endorsement node set after the endorsement nodes are subjected to simulated transaction verification, and if the endorsement results received by the terminal equipment are successful and the endorsement nodes returning the endorsement results meet preset conditions, a plurality of service sub-information containing the endorsement results are submitted to preset consensus nodes; and if the endorsement result of the endorsement failure exists, stopping accounting the complex service information. For example, the preset condition may be that the endorsement nodes returning the endorsement result reach a preset endorsement number (for example, if the endorsement node set includes 10 endorsement nodes, the endorsement number may be set to 7), and the endorsement result returned by receiving a specified endorsement node or nodes may also be received. After receiving the plurality of service sub-information containing endorsement results, the consensus node of the block chain performs consensus verification on the plurality of service sub-information containing endorsement results in the block chain. In the embodiment of the present invention, the blockchain is preferably a federation chain, so the consensus node may be a designated node of a designated enterprise in the enterprise that constructs the federation chain, and the algorithm for performing consensus verification by the consensus node may adopt a Practical Byzantine Fault Tolerance (PBFT) algorithm or a Delegated Proof of authority (DPOS) algorithm, etc. And after the consensus verification is passed, the consensus node informs all nodes in the block chain to add a plurality of service sub-information containing endorsement results into the block chain in a block form, so as to complete the accounting of the complex service information in the block chain account book.
As can be seen from the embodiment shown in fig. 1, in the embodiment of the present invention, complex service information is split into multiple pieces of service sub information, the multiple pieces of service sub information are submitted to endorsement nodes, and simulated transaction verification is performed one by one, and if the endorsement results returned by the endorsement nodes are successful in endorsement and the endorsement nodes of the returned endorsement results satisfy a preset condition, the multiple pieces of service sub information including the endorsement results are submitted to a consensus node for performing simulated transaction verification one by one.
Fig. 2 is a diagram showing a method obtained by expanding a process after submitting a plurality of business sub-information to an endorsement node set on the basis of the first embodiment of the present invention. The embodiment of the present invention provides an implementation flowchart of a block chain-based service billing method, as shown in fig. 2, the service billing method may include the following steps:
in S201, if the received endorsement results are successful in endorsement, but the endorsement nodes returning the endorsement results do not meet the preset condition, determining the endorsement nodes not returning the endorsement results as target nodes, and submitting the plurality of service sub-information to the target nodes again, where the target nodes are in an online state.
In the embodiment of the present invention, if the terminal device submits the plurality of service sub information to the endorsement node set, the received endorsement results are successful in endorsement, but the endorsement nodes returning the endorsement results do not satisfy the preset condition, for example, the endorsement nodes returning the endorsement results do not reach the preset endorsement number, the terminal device determines the endorsement nodes not returning the endorsement results as the target nodes, and submits the plurality of service sub information to the target nodes again. It should be noted that, since the terminal device cannot establish communication connection with the endorsement node in the offline state, and naturally cannot receive the endorsement result returned from the endorsement node in the offline state, when determining the target node, the endorsement nodes in the endorsement node set in the online state are determined first, and then the endorsement nodes in the online state and not returning the endorsement result are determined as the target nodes.
In S202, if receiving an endorsement acceptance prompt of the target node about the plurality of service sub-information, monitoring the target node, and giving an alarm when the endorsement result returned by the target node is not received within a preset time period.
After submitting the plurality of service sub-information to the target node, the terminal equipment monitors data returned by the target node if receiving an endorsement acceptance prompt (the endorsement acceptance prompt is used for prompting the target node to endorse the plurality of service sub-information). If the terminal device does not receive the endorsement result returned by the target node within the preset time period, the target node is proved to have problems in the endorsement process (if the computing resources of the target node are greatly occupied by other programs), the terminal device gives an alarm based on the target node. The preset time period may be determined based on an average endorsement duration of a plurality of past complex service information, for example, the average endorsement duration is 8 minutes, and then the preset time period may be set to be slightly longer than the average endorsement duration, for example, to be 10 minutes.
In S203, if a rejection endorsement prompt of the target node about the plurality of service sub information is received, repeatedly submitting the plurality of service sub information to the target node at preset submission intervals until receiving the acceptance endorsement prompt of the target node.
On the other hand, if the terminal device receives the endorsement rejection prompt returned by the target node after submitting the plurality of service sub-information to the target node, because the target node may be in a situation that the occupancy rate is too high and the endorsement cannot be performed, the terminal device repeatedly submits the plurality of service sub-information to the target node at preset submission intervals (for example, 1 minute) until the occupancy rate of the target node is reduced and the endorsement can be performed, that is, the terminal device receives the endorsement acceptance prompt returned by the target node.
As can be seen from the embodiment shown in fig. 2, in the embodiment of the present invention, if the endorsement results received by the terminal device are successful in endorsement, but the endorsement nodes returning the endorsement results do not meet the preset condition, the endorsement nodes not returning the endorsement results are determined as target nodes, and the plurality of service sub-information are submitted to the target nodes again, and after the submission is completed, if the terminal device receives an endorsement acceptance prompt returned by the target nodes, an alarm is given when the endorsement results are not received within the preset time period; if the terminal equipment receives the endorsement rejection prompt returned by the target node, the plurality of service sub-information are repeatedly submitted to the target node at preset submission intervals until the endorsement acceptance prompt of the target node is received.
Fig. 3 is a diagram that is obtained by refining a process of submitting a plurality of service sub-information to an endorsement node set on the basis of the first embodiment of the present invention, where the service sub-information is arranged in an order from a low level to a high level of an originator, and the endorsement node set includes a plurality of endorsement nodes, and each endorsement node corresponds to one originator level. An embodiment of the present invention provides an implementation flowchart of a block chain-based service billing method, and as shown in fig. 3, the service billing method may include the following steps:
in S301, the first service sub information in the plurality of service sub information is analyzed to obtain the level of the initiator of the service sub information.
In the embodiment of the invention, one initiator level is preset for a plurality of initiators possibly appearing in the service, and when the complex service information is serially and sequentially split, the split service sub-information is arranged according to the sequence from the low to the high of the initiator level (because the common services such as the transfer are all from bottom to top). For example, when a user transfers money by using a mobile phone, the user calls an application program on the mobile terminal, then the application program sends a transfer request to a banking institution, and the banking institution finally confirms the transfer request. On the other hand, in the embodiment of the present invention, for endorsement nodes in an endorsement node set, each endorsement node corresponds to an initiator level, that is, each endorsement node maintains a copy of a blockchain account book, but each endorsement node has an endorsement authority, and can only perform simulated transaction verification on service information related to the corresponding initiator level, for example, an endorsement node corresponding to a mobile terminal can only perform simulated transaction verification on service information of which an initiator is a mobile terminal. Based on the above situation, when submitting the plurality of business sub-information to the endorsement node set, first analyzing the first business sub-information in the plurality of business sub-information to obtain the level of the initiator of the business sub-information.
In S302, the endorsement nodes in the endorsement node set that match the originator level are determined as first nodes, and the first service sub-information is submitted to the first nodes for simulated transaction verification.
After the initiator level of the first-order business sub-information is determined, endorsement nodes corresponding to the initiator level are searched in the endorsement node set and are determined as first nodes. Because the first node has the endorsement authority to the service information related to the initiator level, the first service sub-information is submitted to the first node for simulation transaction verification. The number of the first nodes can be one or more than one.
In S303, after receiving the endorsement result and the simulated transaction result returned by the first node, analyzing a second node corresponding to the next service sub-information, and submitting the endorsement result, the simulated transaction result, and the next service sub-information to the second node for simulated transaction verification until all the service sub-information is submitted.
In the embodiment of the invention, after the verification of the simulated transaction is completed, the endorsement node in the endorsement node set generates a simulated transaction result in addition to the endorsement result. For example, the first business sub-information is "Account A Account to Account B Transfer 100 Yuan, after the business sub-information is submitted to the first node, if the first node verifies the simulated transaction of the business sub-information successfully, the endorsement result generated by the first node is successful, and in the simulated transaction result generated by the first node, the Account is Account A Account balance of (2) has been reduced by 100 yuan, account B Has increased by 100 dollars. After receiving the endorsement result and the simulated transaction result returned by the first node, if the endorsement result is successful, the terminal equipment analyzes the next service sub-information of the first service sub-information to obtain a second node corresponding to the next service sub-information in the endorsement node set, and sends the endorsement result, the simulated transaction result and the simulated transaction result to the terminal equipmentAnd submitting the next service sub-information to the second node for endorsement, and repeating the process until all the service sub-information is endorsed completely. In addition, in the embodiment of the present invention, a node condition may be set for each initiator level, the node conditions of multiple initiator levels may be set to be the same or different, and for the endorsement result of a certain service sub-information, the terminal device performs the endorsement of the next service sub-information after judging that the endorsement node returning the endorsement result satisfies the corresponding node condition.
Optionally, if the endorsement result returned by the first node is an endorsement failure, stopping accounting for the plurality of service sub-information, and generating and outputting error information based on the simulated transaction result and the service sub-information corresponding to the simulated transaction result. If the endorsement result returned by the first node (or the endorsement node corresponding to other initiator levels) is an endorsement failure, the terminal device stops bookkeeping of the plurality of service sub-information, and generates and outputs error information based on the simulated transaction result generated by the first node and the service sub-information corresponding to the simulated transaction result, so that a user can conveniently search the reason of the bookkeeping failure from the error information, such as insufficient balance of a user account, and the coping mechanism of the bookkeeping failure condition is perfected.
As can be seen from the embodiment shown in fig. 3, in the embodiment of the present invention, an initiator level is obtained by analyzing the first-position business sub-information in the multiple business sub-information, an endorsement node in a set of endorsement nodes that matches the initiator level is determined as a first node, the first-position business sub-information is submitted to the first node for simulated transaction verification, after receiving the endorsement result and the simulated transaction result returned by the first node, a second node corresponding to the next business sub-information is analyzed, and the endorsement result, the simulated transaction result and the next business sub-information are submitted to the second node for simulated transaction verification until all the business sub-information is submitted.
Fig. 4 is a method obtained by refining a process of determining endorsement nodes corresponding to an initiator level in an endorsement node set as first nodes and submitting first-order service sub-information to the first nodes for simulated transaction verification, on the basis that each initiator level corresponds to a preset key pair, each key pair comprises a public key and a private key, and each endorsement node holds a private key corresponding to its own initiator level, and the endorsement nodes in the endorsement node set correspond to the initiator level. The embodiment of the present invention provides an implementation flowchart of a block chain-based service billing method, as shown in fig. 4, the service billing method may include the following steps:
in S401, respectively encrypting the plurality of service sub-information according to the public key corresponding to the initiator level, encrypting preset verification information according to the public key corresponding to the first service sub-information, and sending the encrypted verification information to each endorsement node in the endorsement node set, where the endorsement node is configured to decrypt the encrypted verification information according to its own private key to obtain a decryption result.
In the embodiment of the present invention, each initiator level corresponds to a key pair, each key pair includes a public key and a private key, and the key is preferably generated by an asymmetric encryption algorithm, such as an Elliptic Curve Cryptography (ECC) or an RSA encryption algorithm. The endorsement node holds a private key corresponding to the level of the initiator of the endorsement node, and the terminal equipment at least holds a public key corresponding to each level of the initiator. After the terminal equipment splits the complex service information into a plurality of service sub-information, encrypting each service sub-information according to the public key corresponding to the level of the initiator, and encrypting the preset verification information according to the public key corresponding to the first service sub-information. After encryption is completed, the terminal equipment sends the encrypted verification information to a plurality of endorsement nodes in the endorsement node set, wherein the verification information can be set in a user-defined mode.
