Detailed Description

For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure. Embodiments and features of embodiments in this application may be combined with each other arbitrarily without conflict. Also, while a logical order is depicted in the flowchart, in some cases, the steps depicted or described may be performed in a different order than presented herein.

The terms first and second in the description and claims of the present application and in the above-described figures are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the term "include" and any variations thereof is 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 listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus. The term "plurality" in the present application may mean at least two, for example, two, three or more, and embodiments of the present application are not limited.

In addition, the term "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. The character "/" herein generally indicates that the associated object is an "or" relationship unless otherwise specified.

The technical field of financial science (Fintech) generally relates to various transactions, for example, a transaction of a bank may include a card selling transaction, a deposit transaction, a loan transaction, an insurance transaction, a financial transaction, etc., and the daily transaction amount of the bank may reach thousands or even tens of thousands. With the development of blockchain technology, the financial science and technology field can also use blockchain technology to process transactions, for example, if related transactions are related among a plurality of banks, related transactions can be synchronously processed by setting a alliance chain, or courts, clients and the like can be simultaneously and uplink to jointly maintain the security and stability of the alliance chain.

The blockchain system may be a point-To-point (P2P) network consisting of a plurality of nodes. P2P is an application layer protocol that runs on top of the transmission control protocol (Transmission Control Protocol, TCP) protocol, nodes in a blockchain system can peer to each other, there is no central node in the system, and thus each node can randomly connect to other nodes. In the blockchain system, a preset database can be arranged in each node, each node maintains a public account book in the blockchain system through the preset database, and the preset database in the node can store the block data in the blockchain system; the block data comprises a block header and a block body, the block header comprises information such as a hash value of the previous block, a hash value of the current block, a block height of the current block, a time stamp and the like, and the block body comprises transaction data, such as transaction data to be processed in the process of consensus of the block by a node in a block chain system and transaction results obtained by processing the transaction data to be processed.

Nodes in a 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 the transaction data and other information transmitted by other nodes to more nodes so as to realize the communication between the nodes; alternatively, nodes in the blockchain system may be used to support transactions by users; alternatively, nodes in the blockchain system may be used to record all transactions historically (e.g., such nodes may be referred to as full nodes); alternatively, nodes in the blockchain system may generate new blocks in the blockchain by validating and recording transactions.

In the related art for processing financial services through blockchains, each blockchain corresponds to a specific service type, and each service type corresponds to an account book. When a certain node initiates a transaction, all nodes associated with the transaction receive a corresponding request and perform corresponding state transition processing. For example, a transaction is currently initiated by a node, which is that user a pays 10 digital currencies to user B, and the transaction is that requiring tax payment, then the full node of the blockchain processing the funds settlement chain processes the corresponding funds settlement state transition based on the transaction, and the full node of the blockchain processing the tax payment transaction processes the tax payment service 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 various services. It should be noted that, each blockchain corresponds to a plurality of full nodes that process traffic, and these full nodes can only process state transitions of the corresponding blockchain, that is, each full node can only process traffic state transitions of one blockchain. And when the state of a certain link is converted, each full node realizes state conversion through the same service processing module of the full node, and when the state is converted, the state is also converted and confirmed through the same common module of the full node. Thus, each full node can only process the own service state transition, so that the service processing efficiency of the block chain system is lower.

In view of this, the embodiment of the present application provides a service processing method of a blockchain system, by which a full node can divide a service into a plurality of sub-services after receiving the service, and then the corresponding blockchain processes the plurality of sub-services, and can make a consensus on a service processing result through the full node, and can issue the consensus result to each blockchain, so that after each blockchain stores a service state of a self-tag, the service states of other blockchains can be stored in the own blockchain, thereby improving the service processing efficiency of the blockchain system, and when related information of a transaction needs to be checked, only accessing one blockchain can obtain a plurality of state information of the transaction, and improving the checking efficiency.

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

Referring to fig. 1, fig. 1 is an application scenario to which the technical solution of the embodiment of the present application may 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, there are 2 full nodes, 2 blockchains, and 4 nodes in each blockchain, for example, node 1, node 2, node 3, and node 4, where it should be noted that the nodes included in each blockchain may be full nodes or light nodes, so any one of nodes 1 to 4 may be full nodes or light nodes, and this is not a limitation. Any two of nodes 1-4 in each blockchain may be communicatively coupled to collectively maintain the blockchain system. When a transaction occurs, the full node receives the transaction, divides the transaction into different subtasks according to the business processing types contained in the transaction, distributes the subtasks to corresponding blockchains for corresponding processing, and reports corresponding processing results to the full node after the blockchains are processed. 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, where the client device may be connected to any full node in the blockchain system through an access blockchain network. In particular implementations, the client device may send the transaction to any full node in the blockchain system, and after receiving the transaction, a full node in the blockchain system may synchronize the transaction to other nodes in the blockchain system to perform the corresponding task.

In the application scenario shown in fig. 1, each blockchain corresponds to one service ledger, and all nodes in the blockchain system are respectively connected with two blockchains, that is, each of the full nodes can process two service ledgers at the same time, so that there may be a plurality of consensus modules and service processing modules corresponding to each of the full nodes. The consensus module is used for realizing consistency of account book state conversion among different nodes, and the business processing module is used for carrying out state conversion of each account book.

The following describes the technical scheme provided by the embodiment of the application with reference to the attached drawings.

Referring to fig. 2, fig. 2 is a flowchart of a service processing method of a blockchain system according to an embodiment of the present application. The following description will take an example of the application of the method in an application scenario as shown in fig. 1. The description of the flow chart is as follows:

Step 201: one of the full nodes in the blockchain system receives a first service that includes identification information of the first service.

In one possible embodiment, the blockchain system may include multiple full nodes, and when receiving the service, any one of all the full nodes may receive, specifically, which full node may receive, according to the actual situation, for example, may receive the full node closest to the service, or may receive the full node with the smallest current load, and the like, which is not limited herein. In the application scenario shown in fig. 1, for example, the current service is received by the full node 1, the service may be understood as a first service, where the first service includes identification information of the service, where the identification information is attribute information used to indicate that the service includes, and the attribute information may be, for example, whether the transaction needs tax payment, whether the transaction needs invoice, or whether the transaction needs invoice, and so on, which is not limited herein.

For example, the identification information may be in the form of a digital code, for example, the first digit is used to determine whether the business needs tax payment, the first digit is "0" is determined that the transaction does not need tax payment, the first digit is "1" is determined that the transaction needs tax payment, after the whole node receives the business, whether the business needs tax payment can be determined according to the first digit data code of the identification information, and the first digit data code of the first business is determined to be "1" on the assumption that the transaction needs tax payment.

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

In one possible implementation, after the full node receives the first service, the specific service condition of the transaction may be determined according to the identification information, and then the transaction is divided into a plurality of sub-services. For example, the first service is determined to include two attribute information of fund settlement and tax payment according to the identification information of the first service, and then the first service can be divided into two corresponding fund settlement, tax payment and two sub-services, wherein the two sub-services respectively correspond to one blockchain, that is, the fund settlement service corresponds to the fund settlement blockchain and the tax payment service corresponds to the tax payment transaction blockchain. In a specific implementation process, the number of sub-services may be more, which is not limited in the embodiments of the present application.

For example, taking the application scenario of fig. 1 as an example, adding the blockchain 1 corresponds to a fund settlement chain, and the blockchain 2 corresponds to a tax payment transaction chain, assuming that there is a transaction currently: a pays B100 digital currencies and the transaction requires tax payment. After the A initiates the request of paying 100 digital currencies to the B, any one of the full nodes 1 and 2 receives the transaction, and the full node receives the transaction and divides the transaction into two subtasks, namely a fund settlement task and a tax payment transaction task, then the full node sends the fund settlement task to a corresponding fund settlement chain (namely a block chain 1) and sends the tax payment transaction task to a corresponding tax payment transaction chain (namely a block chain 2), and the block chain 1 and the block chain 2 can process corresponding business content after receiving the task issued by the full node.

Step 203: the full node sends the plurality of sub-services to the corresponding blockchain respectively.

After dividing the first service into a plurality of sub-services, the full node may send the plurality of sub-services to the corresponding blockchain respectively, so that the corresponding blockchain processes its own related service, for example, sends the funds accounting sub-service to the funds accounting chain, so that the funds accounting chain processes the service. It should be noted that, when the all nodes issue sub-services to the blockchain, the sub-services may be issued simultaneously or may be issued separately in sequence, which is not limited in the embodiment of the present application.

Step 204: each blockchain of the plurality of blockchains of the blockchain system receives sub-traffic sent 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 blockchains respectively, each blockchain receives the sub-service corresponding to the blockchain, and then performs corresponding processing, for example, the tax payment transaction block links receive the tax payment processing service included in the first service sent by the full node, and then performs corresponding tax payment processing.

Step 205: after the received sub-service is processed, the block chain sends a first processing result corresponding to the sub-service to the full node.

After processing the sub-service issued by the full node, each blockchain reports its own processing result to the full node, for convenience of distinguishing, for example, the processing result is the first processing result.

In one possible implementation, after the full node issues the sub-services to the blockchains, since the content of each blockchain processing service is different, and the processing speed may be different, when a blockchain reports its own 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, then receive the first processing result of the other blockchains, or may process all blockchains together to process its own sub-services, then report the first processing result to the full node simultaneously, and then the full node may receive the first processing result reported by the blockchains that process all the sub-services simultaneously, or when the number of sub-services exceeds two, it may also receive the first processing results of two blockchains simultaneously, then receive the first processing results of the other blockchains.

For example, in the present case, for example, two sub-services, a fund settlement service and a tax payment service, assuming that the fund settlement chain may be processed first and then the processing result is reported to the full node, the full node receives the first processing result of the fund settlement chain first and then receives the first processing result of the tax payment transaction chain, or the fund calculation chain and the tax payment transaction chain report the own first processing result to the full node at the same time, and then the full reception you receive the two first processing results at the same time.

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

In one possible implementation manner, after receiving the first processing results reported by the blockchains corresponding to each sub-service, the full node also needs to receive verification information of each blockchain on each first processing result, and then determines whether the received first processing result is correct or not according to the verification information. Each piece of verification information is obtained by verifying the first processing results of other blockchains through each blockchain, each piece of verification information can be verification passing or verification failing, if the verification information is verification passing, the blockchain can be indicated to determine that the first processing result of the current verification is correct, and correspondingly, if the verification information is verification failing, the blockchain can be indicated to determine that the first processing result of the current verification is incorrect.

In a specific implementation process, after a certain blockchain of the processing subtask finishes processing the subtask, a first processing result is reported to the full node, and meanwhile, the first processing result of the processing subtask is also sent to other blockchains, so that the other blockchains verify the first processing result of the processing subtask, and accordingly, each blockchain receives the processing result corresponding to the other blockchains sent by the other blockchains to the processing result of the processing subtask, for convenience of distinguishing, for example, the processing result sent by the blockchain to the other blockchains can be called as a third processing result. Each blockchain may receive the third processing result sent by a plurality of other blockchains at the same time, or may receive the third processing result sequentially, which is not limited herein.

After a certain block link receives the third processing result sent by other block links, the third processing result is verified, and then the verification result is reported to the full node. It should be noted that, for the same third processing result, when different blockchains verify the same third processing result, the same consensus algorithm is generally required to verify the same third processing result, so that consistency and 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 the corresponding first processing result. For example, there are three blockchains currently processing the sub-service, namely, blockchain 1, blockchain 2, blockchain 3 and blockchain 4, and then after the blockchain 1 reports the first processing result, the full node needs to receive the verification information of the first processing result of blockchain 1 by blockchain 2, blockchain 3 and blockchain 4, and then determine whether the first processing result of blockchain 1 is correct. Assuming that the validation information sent by blockchain 2 and blockchain 3 for the first processing result of blockchain 1 is validated, then it is indicated that blockchain 2 and blockchain 3 consider the first processing result of blockchain 1 as correct, and if the validation information sent by blockchain 4 for the first processing result of blockchain 1 is validated to fail, then it is indicated that blockchain 4 considers the first processing result of blockchain 1 as incorrect.

In one possible implementation manner, after receiving a plurality of pieces of verification information for a certain first processing result, the full node determines the plurality of pieces of verification information to determine whether the first processing result is correct, and further obtains a second processing result corresponding to the first processing result, where the second processing result is the verification result after verifying the first processing result, 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 the processing result opposite to the first processing result.

In one possible implementation, the full node that receives the first service may include a plurality of service processing modules and a plurality of consensus modules, where each sub-service corresponds to a service processing module. Different sub-services can be respectively sent to corresponding block chains through the service processing module, and then verification information aiming at a certain first processing result is received through a certain consensus module and subjected to consensus processing. The number of traffic handling modules and the number of consensus modules may not be equal. Each sub-service performs consensus through which consensus module, which consensus module is required to be used for the service can be determined according to actual conditions, for example, the sub-service is appointed, or the corresponding relation 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 blockchain 1, the service processing module 2 sends the sub-service 2 to the blockchain 2, then the preset corresponding to the service processing module 1 is the consensus module 1, the corresponding to the service processing module 2 is the consensus module 2, then for the first processing result reported by the blockchain 1, the consensus module 1 is used to receive the verification information sent by other blockchains, and the consensus module 1 obtains the corresponding second processing result, that is, the consensus of the first processing result of the blockchain 1 is carried out through the consensus module 1, for the first processing result reported by the blockchain 2, the consensus module 2 is used to receive the verification information sent by other blockchains, and the consensus module 2 obtains the corresponding second processing result, that is, the consensus of the first processing result of the blockchain 2 is carried out through the consensus module 2; alternatively, the service processing module 1 and the service processing module 2 may both correspond to the consensus module 1, and the first processing results reported by the blockchain 1 and the blockchain 2 are commonly known by the consensus module 1.

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

For example, there are ten blockchain processing sub-services currently, and the first processing result reported for the tax-paying transaction chain is tax-paid, then the full node receives the verification information of the other 9 blockchains on the first processing result, assuming that the preset number is 5, and the verification information of the first processing result of the 6 blockchains for the tax-paying transaction chain in the 9 blockchains is verification passing, the first processing result is considered correct, that is, tax-paying has been performed, the second processing result corresponding to the first processing result is tax-paid, or the verification information of the first processing result of the 3 blockchains for the tax-paying transaction chain in the 9 blockchains is verification passing, that is, the first processing result is error, that is, the current transaction is not tax-paid, and the second processing corresponding to the first processing result is not tax-paid.

Step 207: the full node issues at least one second processing result to each blockchain.

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

Step 208: the blockchain receives and saves at least one second processing result.

In one possible implementation, after each blockchain receives at least one second processing result issued by the full node, the second processing result may be saved in a primary state and at least one secondary state, where the primary state may be understood as a processing result corresponding to the blockchain, and the secondary state may be understood as a processing result of other blockchains received by the blockchain. It should be noted that, each blockchain processes one sub-service, so each blockchain has only one main state, but may have multiple sub-states. Alternatively, the primary state may be understood as a change in the object of the ledger tag 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, for the fund settlement chain, it records the respective fund amount of the owners, then the fund amount is the object of the chain mark, when the fund amount is changed, 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 record the tax-paying state of the transaction, the tax-paying state can be understood as the attribute of the fund settlement chain, the attribute can comprise two different states, namely a tax-paying state and a non-tax-paying state, when the transaction just happens, the tax-paying process is probably not performed, that is, the tax-paying state attribute of the fund payment chain is non-tax-paying, and after the tax-paying transaction chain processes the tax-paying business of the transaction, the fund settlement chain can convert the tax-paying state attribute into the tax-paying state, and the condition can be understood as the secondary state conversion.

That is, each blockchain may record the processing results of other blockchains associated with its own blockchain, and when a user obtains the relevant state information of a transaction corresponding to a blockchain, the state information of other blockchains associated with the blockchain may be obtained synchronously. Compared with the prior art, 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 fund settlement and the acquiring mode of the related state information of tax payment, the business processing method provided by the embodiment of the application can realize that when the fund settlement link is accessed to acquire the fund settlement information of whether the transaction pays, the user can also acquire the tax payment state information of whether the transaction pays tax, and the acquiring efficiency is improved.
