Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the accompanying 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. In the present application, the embodiments and features of the embodiments may be arbitrarily combined with each other without conflict. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

The terms "first" and "second" in the description and claims of the present application and the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the term "comprises" and any variations thereof, which are intended to cover non-exclusive protection. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. The "plurality" in the present application may mean at least two, for example, two, three or more, and the embodiments of the present application are not limited.

In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document generally indicates that the preceding and following related objects are in an "or" relationship unless otherwise specified.

The field of financial technology (Fintech) generally involves many transactions, for example, bank transactions may include card-selling transactions, deposit transactions, loan transactions, insurance transactions, financing transactions, etc., and the daily transaction amount of a bank may reach thousands or even tens of thousands. With the development of the blockchain technology, the field of financial technology may also use the blockchain technology to process transactions, for example, if related transactions are involved between multiple banks, the related transactions may be processed synchronously by setting up a federation chain, or a court, a customer, and the like may be linked up simultaneously to maintain the security and stability of the federation chain together.

The blockchain system may be a point-To-point (Peer To Peer, P2P) network composed of a plurality of nodes. P2P is an application layer Protocol running on top of the Transmission Control Protocol (TCP), nodes in a blockchain system can be peer-to-peer with each other, and there is no central node in the system, so each node can randomly connect to other nodes. In the block chain system, a preset database can be arranged in each node, each node commonly maintains a public ledger in the block chain system through the preset database, and the preset database in each node can store block data in the block chain system; the block data includes a block head and a block body, the block head includes information such as a hash value of a previous block, a hash value of the block, a block height of the block, a timestamp, and the like, and the block body includes transaction data, such as transaction data to be processed in a process that a node in a block chain system recognizes the block and a transaction result obtained by processing the transaction data to be processed.

Nodes in the blockchain system may have a variety of functions, such as routing functions, transaction functions, blockchain functions, consensus functions, and the like. Specifically, the nodes in the blockchain system can transmit information such as transaction data transmitted by other nodes to more nodes to realize communication between the nodes; alternatively, nodes in the blockchain system may be used to support users in conducting transactions; alternatively, a node in the blockchain system may be used to record all transactions historically (e.g., such a node may be referred to as a full node); alternatively, a node in the blockchain system may generate a new block in the blockchain by verifying and recording the transaction.

In the related technology for processing the fiscal and taxable business through the block chains, each block chain corresponds to a specific business type, and each business type also corresponds to an account book. When a certain node initiates a transaction, all nodes related to the transaction receive corresponding requests and perform corresponding state transition processing. For example, when a transaction is initiated by a node, the user a pays 10 bitcoins to the user B, and the transaction needs to be taxed, then the whole nodes of the fund settlement chain are processed in the blockchain, the corresponding fund settlement state conversion is processed based on the transaction, and the whole nodes of the blockchain for processing tax payment transactions process tax payment services corresponding to the transaction according to the relevant processing rules of tax payment.

That is, each transaction-related service is processed through the full nodes corresponding to the various services. It should be noted that each blockchain corresponds to a plurality of full nodes for processing services, and these full nodes can only process the state transition of the corresponding blockchain, that is, each full node can only process the service state transition of one blockchain correspondingly. And the whole node in each block chain corresponds to a consensus module and a service processing module, when the state of a certain link is converted, each whole node realizes the state conversion through the same service processing module of the whole node, and when the consensus is carried out, the consensus is also carried out through the same consensus module of the whole node. Therefore, each full node can only process self service state conversion, so that the service processing efficiency of the block chain system is low.

In view of this, an embodiment of the present application provides a service processing method for a blockchain system, where by the method, after receiving a service, a full node may divide the service into multiple sub-services, and then process the multiple sub-services by a corresponding blockchain, and the full node may perform consensus on a service processing result and may issue the consensus result to each blockchain, so that after each blockchain stores a service state marked by itself, the service states of other blockchains may also be stored in its blockchain, which improves service processing efficiency of the blockchain system.

In order to facilitate understanding of the technical solutions provided in the embodiments of the present application, some brief descriptions are provided below for application scenarios used in the technical solutions provided in the embodiments of the present application, and it should be noted that the application scenarios described below are only used for illustrating the embodiments of the present invention and are not limited. In specific implementation, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.

Please refer to fig. 1, where fig. 1 is an application scenario to which the technical solution of the embodiment of the present application can be applied. In the application scenario shown in fig. 1, the blockchain system may include a plurality of blockchains and a plurality of full nodes, each blockchain may include one or more nodes, in fig. 1, the plurality of full nodes is 2, the plurality of blockchains is 2, and each blockchain has 4 nodes as an example, and the 4 nodes are respectively node 1, node 2, node 3, and node 4, it should be noted that each blockchain includes nodes that may be full nodes or light nodes, so any node of node 1 to node 4 may be a full node or a light node, which is not limited herein. Any two nodes of the nodes 1 to 4 in each block chain can be connected in communication, so that the block chain system is maintained together. When a transaction occurs, the whole node receives the transaction, then divides the transaction into different subtasks according to the service processing type contained in the transaction, then distributes the subtasks to corresponding block chains for corresponding processing, and reports corresponding processing results to the whole node after the processing of each block chain is finished. It should be noted that a node in the blockchain system may be on a physical machine (server), and a node may specifically refer to a process or a series of processes running in the server.

As shown in fig. 1, the application scenario may further include a client device, and the client device may be connected to any full node in the blockchain system through an access blockchain network. In a specific implementation, the client device may send the transaction to any whole node in the blockchain system, and after receiving the transaction, a whole node in the blockchain system may synchronize the transaction to other nodes in the blockchain system to execute a corresponding task.

In the application scenario shown in fig. 1, each blockchain corresponds to one service account book, and all nodes in the blockchain system are respectively connected to two blockchains, that is, each all node can process two service account books simultaneously, so that there may be a plurality of consensus modules and service processing modules corresponding to each all node. The common recognition module is used for realizing the consistency of state conversion of the accounts among different nodes, and the business processing module is used for performing the state conversion of each account.

The technical scheme provided by the embodiment of the application is described in the following with the accompanying drawings of the specification.

Referring to fig. 2, fig. 2 is a flowchart of a service processing method of a block chain system according to an embodiment of the present application. The method is described below as applied to the application scenario shown in fig. 1.

The flow diagram is described as follows:

step 201: one of the full nodes in the blockchain system receives a first service, and the first service comprises identification information of the first service.

In a possible embodiment, a plurality of full nodes may be included in the blockchain system, and when receiving a service, any one of all the full nodes may receive the service, and which full node receives the service may be determined according to actual situations, for example, the full node closest to the service may receive the service, or the full node with the smallest current load may receive the service, and so on, which is not limited herein. In the application scenario shown in fig. 1, for example, the full node 1 receives a current service, the service may be understood as a first service, the first service includes identification information of the service, the identification information is attribute information used for indicating that the service includes, and the attribute information may be, for example, whether the transaction requires tax payment or whether the transaction requires invoicing, or the like, which is not limited herein.

For example, the identification information may be in the form of a digital code, for example, the first digit determines whether the transaction needs to be taxed, the first digit "0" determines that the transaction does not need to be taxed, and the first digit "1" determines that the transaction needs to be taxed, so that after the whole node receives the transaction, the whole node may determine whether the transaction needs to be taxed according to the first digit data code of the identification information therein, and assuming that the first digit data code of the first transaction is determined to be "1", it is determined that the transaction needs to be taxed.

Step 202: and the full node divides the first service into a plurality of sub-services according to the received identification information of the first service, wherein each sub-service corresponds to one of the block chains.

In a possible implementation manner, after receiving the first service, the full node may determine a specific service condition of the transaction according to the identification information, and then divide the transaction into a plurality of sub-services. For example, it is determined that the service includes two attribute information of fund settlement and tax payment according to the identification information of the first service, the first service may be divided into two corresponding sub-services of fund settlement, tax payment and tax payment, where the two sub-services respectively correspond to one block chain, that is, the fund settlement service corresponds to the fund settlement block chain, and the tax payment service corresponds to the tax payment transaction block chain. In a specific implementation process, the number of the sub-services may be more, and the embodiment of the present application is not limited.

For example, taking the application scenario of fig. 1 as an example, adding blockchain 1 corresponds to a fund settlement chain, and adding blockchain 2 corresponds to a tax payment transaction chain, assuming that there is a transaction: a pays 100 bitcoins to B, and the transaction needs to be taxed. After a initiates a request for paying 100 bitcoins to B, any one of the full node 1 and the full node 2 receives the transaction, and if the transaction is received by the full node 1 and divided into two subtasks, which are a fund settlement task and a tax payment transaction task, the full node sends the fund settlement task to the corresponding fund settlement chain (i.e. the blockchain 1) and sends the tax payment transaction task to the corresponding tax payment transaction chain (i.e. the blockchain 2), and after the tasks issued by the full node are received, the blockchain 1 and the blockchain 2 can process corresponding business contents.

Step 203: and the whole node respectively sends the plurality of sub-services to the corresponding block chains.

After the first service is divided into a plurality of sub-services, the full node may send the plurality of sub-services to corresponding block chains, respectively, so that the corresponding block chains process their own related services, for example, send the fund ending sub-service to the fund settlement chain, so that the fund settlement chain processes the service. It should be noted that when the whole node issues the sub-service to the block chain, the sub-services may be issued simultaneously or may be issued sequentially and respectively, and the embodiment of the present application is not limited.

Step 204: each of a plurality of block chains of the block chain system receives sub-traffic transmitted by one of the at least one full node.

In a specific embodiment, after the full node sends the divided sub-services to the corresponding block chains, each block chain receives the sub-service corresponding to itself, and then performs corresponding processing, for example, the tax payment transaction block chain receives the tax payment processing service included in the first service sent by the full node, and then performs corresponding tax payment processing.

Step 205: and after the block chain processes the received sub-services, sending a first processing result corresponding to the sub-services to the full node.

Each block chain reports its own processing result to the full node after processing the sub-service delivered by the full node, and for convenience of differentiation, for example, the processing result is the first processing result.

In a possible implementation, after the full node issues the sub-services to the blockchains, since the content of the services processed by each blockchain is different, and the processing speed may also be different, when a certain blockchain reports its first processing result to the full node, other blockchains may not have processed the corresponding sub-services yet, so the full node may only receive the first processing result of one blockchain first and then receive the first processing result of the other blockchain, or may also finish processing its own sub-services together with all blockchains and then report the first processing result to the full node at the same time, and then the full node may simultaneously receive the first processing results reported by all blockchains processing the sub-services at this time, or, when the number of the sub-services exceeds two, may also receive the first processing results of two blockchains at the same time, then, the first processing result of another block chain is received, and the receiving time and the receiving sequence of the first processing result on the block chain are received by all nodes, which is not limited in the embodiment of the present application.

For example, currently, two sub-services, a fund settlement service and a tax payment processing service, assume that a fund settlement chain may be processed first and then the processing result is reported to a whole node, then the whole node receives a first processing result of the fund settlement chain first and then receives a first processing result of a tax payment transaction chain, or a fund calculation chain and a tax payment transaction chain report their first processing results to the whole node at the same time, and then you all wait for receiving two first processing results at the same time.

Step 206: and the full node receives at least one first processing result sent by the plurality of block chains, and obtains at least one second processing result corresponding to the at least one first processing result.

In a possible implementation manner, after receiving the first processing result reported by the block chain corresponding to each sub-service, the full node further needs to receive the verification information of each block chain on each first processing result, and then determines whether the received first processing result is correct through the verification information, which may be understood as a consensus process, that is, it is necessary to achieve consensus on the processing result of a certain sub-task according to the verification information of all block chains. Each piece of verification information is obtained by verifying the first processing result of other blockchains through each blockchain, each piece of verification information can be verified or failed, if the verification information is verified, the blockchain can be indicated to determine that the first processing result currently verified is correct, and correspondingly, if the verification information is verified to be failed, the blockchain can be indicated to determine that the first processing result currently verified is wrong.

In a specific implementation process, after a certain block chain that processes a subtask has processed the subtask, the first processing result is reported to all nodes, and meanwhile, the first processing result of the certain block chain is sent to other block chains, so that the other block chains verify the first processing result of the certain block chain. Each blockchain may receive the third processing results sent by multiple other blockchains at the same time, or may receive the third processing results sequentially, which is not limited herein.

After a certain blockchain receives the third processing result sent by other blockchains, the third processing result is verified, and then the verification result is reported to the whole node. It should be noted that, for the same third processing result, when different block chains verify the same third processing result, the verification is generally performed by the same consensus algorithm, so that the consistency and the validity of the verification result can be ensured.

It should be noted that, in a specific verification process, each blockchain may not send verification information of its corresponding first processing result. For example, there are three block chains, namely, block chain 1, block chain 2, block chain 3, and block chain 4, of the currently processed sub-service, after the block chain 1 reports the first processing result, the full node needs to receive the verification information of the block chain 2, block chain 3, and block chain 4 on the first processing result of the block chain 1, and then determine whether the first processing result of the block chain 1 is correct. If the verification information sent by blockchain 2 and blockchain 3 for the first processing result of blockchain 1 is verified, it indicates that blockchain 2 and blockchain 3 consider the first processing result of blockchain 1 to be correct, and if the verification information sent by blockchain 4 for the first processing result of blockchain 1 is verified to be failed, it indicates that blockchain 4 considers the first processing result of blockchain 1 to be incorrect.

In a possible implementation manner, after receiving a plurality of pieces of verification information for a certain first processing result, the full node determines, to determine whether the first processing result is correct, so as to obtain a second processing result corresponding to the first processing result, where the second processing result is a verification result after the first processing result is verified, and when the first processing result is correct, the corresponding second processing result is the first processing result, and when the first processing result is incorrect, the second processing result is a processing result opposite to the first processing result.

In a possible implementation manner, the whole node receiving the first service may include a plurality of service processing modules and a plurality of consensus modules, and each sub-service corresponds to one service processing module. Different sub-services can be respectively sent to the corresponding block chains through the service processing module, then the verification information aiming at a certain first processing result is received through a certain consensus module, and the consensus processing is carried out on the verification information. The number of service processing modules and the number of identifying modules may be unequal. The consensus module through which each sub-service performs consensus can be determined according to actual conditions, for example, which consensus module needs to be used by the sub-service is specified in the sub-service, or the corresponding relationship between each service processing module and the consensus module can be preset, and then the corresponding sub-service is sent to the corresponding block chain through each service processing module.

For example, the service processing module 1 sends the sub-service 1 to the block chain 1, the service processing module 2 sends the sub-service 2 to the block chain 2, then a preset consensus module 1 corresponding to the service processing module 1 and a preset consensus module 2 corresponding to the service processing module 2 are set, for the first processing result reported by the block chain 1, the consensus module 1 is used to receive the verification information sent by other block chains, and the consensus module 1 obtains a corresponding second processing result, namely, the consensus module 1 performs consensus on the first processing result of the block chain 1, and for the first processing result reported by the block chain 2, the consensus module 2 is used to receive the verification information sent by other block chains, obtaining a corresponding second processing result by the consensus module 2, namely performing consensus on the first processing result of the block chain 2 through the consensus module 2; or, the service processing module 1 and the service processing module 2 both correspond to the consensus module 1, and the first processing results reported by the block chain 1 and the block chain 2 are both identified by the consensus module 1.

In a specific implementation process, the whole node may respectively calculate how many verification information of the plurality of verification information are verification information that passes verification, if the number of verification information that passes verification in the plurality of verification information is greater than a preset number, the first processing result may be considered to be correct, and correspondingly, when the number of verification information that passes verification is less than or equal to the preset number, it is indicated that the first processing result is incorrect. It should be noted that the preset number may be a preset number value according to an actual service condition, and the preset number value is not limited in the embodiment of the present application.

For example, ten block chain processing sub-services currently exist, the first processing result reported for the tax payment transaction chain is taxed, the full node receives the verification information of the first processing result of the other 9 block chains, assuming that the preset number is 5, and the verification information of the first processing result of the tax payment transaction chain for 6 block chains in the 9 block chains is verified to be passed and exceeds the preset number 5, then it can be considered that the first processing result is correct, that is, tax payment has been performed, the second processing result corresponding to the first processing result is taxed, or the verification information of the first processing result of the tax payment transaction chain for 3 block chains in the 9 block chains is verified to be passed and does not exceed the preset number 5, then it can be considered that the first processing result is wrong, that is the current transaction is not taxed, then the second process corresponding to the result of the first process is not taxed at this time.

Step 207: and the full node transmits at least one second processing result to each block chain.

After obtaining the corresponding second processing result according to each first processing result, the full node sends the obtained second processing result to each block chain, so that each block chain stores the second processing result. Because the second processing result is obtained by the whole node according to the verification information fed back by the block chain in the block chain network, the second processing result can be understood as the achieved consensus result, and thus, the transaction information recorded by all nodes can be effectively ensured to be the same.

Step 208: and the block chain receives and stores at least one second processing result.

In a possible implementation manner, after receiving at least one second processing result issued by the full node, each blockchain may store the second processing result in the form of a main state and at least one auxiliary state, where the main state may be understood as a processing result corresponding to the blockchain, and the auxiliary state may be understood as a processing result of another blockchain received by the blockchain. It should be noted that each blockchain correspondingly processes one sub-service, so each blockchain has only one main state, but there may be multiple sub-states. Alternatively, the primary state may be understood as a change in the object of the ledger flag corresponding to the chain, and the secondary state transition may be understood as a change in the attribute of the chain.

For example, if there is a fund transaction requiring tax payment, and for the fund settlement chain, it records the respective fund amount of the owner, then the fund amount is the object marked by the chain, when the fund amount is sent to change, the main state of the fund settlement chain changes, and the corresponding change becomes the main state transition of the fund settlement chain. Meanwhile, the fund settlement chain can also record the tax payment state of the transaction, the tax payment state can be understood as the attribute of the fund settlement chain, the attribute can comprise two different states, namely tax payment and tax non-payment, when the transaction just occurs, tax payment processing may not be performed, that is, the tax payment state attribute of the fund tax payment chain is tax payment, and after the tax payment business of the transaction is processed by the tax payment transaction chain, the tax payment state attribute is converted into tax payment by the fund settlement chain, and the state conversion can be understood as side state conversion.

That is, each blockchain may record the processing result of other blockchains associated with its own blockchain, and when a user acquires relevant state information corresponding to a certain blockchain for a certain transaction, the state information of other blockchains associated with the blockchain may be acquired synchronously. Compared with the related technology, when a user needs to acquire the state information of a certain transaction in a fund settlement link and a tax payment transaction link, the user needs to access the state information of the fund settlement link and the tax payment transaction link respectively to acquire the related state information of the fund settlement and the related state information of the tax payment.
