In order to facilitate understanding of the technical solutions provided by the embodiments of the present invention, some key terms used in the embodiments of the present invention are explained first.
The block chain is a novel decentralized protocol, digital currency transactions or other data can be safely stored, information cannot be forged and falsified, transaction confirmation on the block chain is completed by all nodes on the block chain together, consistency of the transaction confirmation is guaranteed by a consensus algorithm, a public account book is maintained on the block chain, the public account book is located on a storage block, and any node is visible.
A prolog machine, a mechanism for writing information outside a blockchain into a blockchain, is generally called an oraclemechnism (oracle mechanism). Specifically, the prediction machine has the function of writing external information into the block chain to complete data intercommunication between the block chain and the real world. The method allows the determined intelligent contract to react to the uncertain external world, is the only way for the intelligent contract to perform data interaction with the outside, and is also an interface for the block chain to perform data interaction with the real world.
The technical background of the embodiments of the present invention will be described.
As described above, how to improve the efficiency of the blockchain system is a technical problem to be solved. At present, the blockchain fragmentation technology mainly includes transaction fragmentation, state fragmentation and the like. In the transaction fragment, when a user maliciously creates two transactions with the same input but different outputs, a double-flower transaction occurs. To prevent double-flower transactions, shards would have to communicate with each other frequently, affecting blockchain system efficiency. In state fragmentation, a particular fragment retains only a portion of the state in the blockchain. For example, when there are two shards and two user accounts, each shard will only retain the status of one user, then when two users are conducting transactions, two shards are required to conduct frequent cross-shard communications and status exchanges, affecting blockchain system efficiency.
In order to improve the efficiency of a block chain system, the embodiment of the application provides a fragmentation method applied to a multi-chain system of a finance and tax block chain in combination with the needs of a finance and tax scene.
After introducing the design concept of the embodiment of the present application, some simple descriptions are provided below for application scenarios to which the technical solution of the embodiment of the present application can be applied, and it should be noted that the application scenarios described below are only used for describing the embodiment of the present application 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.
In the embodiment of the application, a fiscal and tax block chain multi-chain system corresponding to a fiscal and tax scene can be established, and the fiscal and tax block chain multi-chain system can comprise an article circulation chain for recording article circulation transactions, a fund settlement chain for recording fund settlement transactions and a tax invoice chain for recording tax payment transactions, for example, according to the needs of the fiscal and tax scene. The three types of block chains have an association in service.
For example, the initial trade of the records of the circulation chain of the goods is generated from the original resources, such as the area and the yield per unit time of a certain medicine field, the reserves and the yield per unit time of a certain mineral deposit, and the subsequent trade is based on the initial trade. The tax invoice chain records tax business and invoice states, and in an invoice issuing link, the issuing information is not directly input, but the circulation transaction of corresponding funds and commodities is taken as an input state, and the reasonability of the circulation transaction is judged according to constraint conditions on the chain, such as whether the yield of raw materials exceeds a reasonable value, whether the transaction frequency is normal, and the like. For any tax invoice chain transaction, corresponding fund settlement transaction and article circulation transaction are used as input states of consumption. After the tax invoice issuing transaction is completed, the invoicing state of the corresponding fund settlement transaction is locked, and cannot be used as the input state of the invoicing transaction, and the invoicing state of the corresponding article circulation transaction is also locked, and cannot be used as the input state of the invoicing transaction.
In a specific implementation process, due to the existence of cycles and different schedules of wide system construction, matched fund settlement is also accepted as the existing bank system and bank transfer system in the block chain multi-chain system. In this case, an online bank settlement prompter node is arranged on the tax invoice chain, effective fund settlement transaction information is obtained through the node, and the state of the fund settlement and invoicing is locked and is recorded by the tax invoice chain.
And the matched article circulation is also accepted as the existing commodity logistics and traceability system. In this case, a node of the commodity circulation prediction machine is arranged on the tax invoice chain, effective commodity circulation information is obtained through the node, and the state of commodity circulation corresponding to invoicing is locked and recorded by the tax invoice chain.
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. 1, fig. 1 is a block chain fragmentation method according to an embodiment of the present disclosure. The flow chart of the method shown in fig. 1 is described as follows:
step 101: and acquiring the attribute information of each node in the block chain.
In the embodiment of the application, when each node of the block chain is added into the block chain, the economic industry type and/or tax payment region to which the node belongs are/is set in a parameter setting mode. When the block chain is deployed on the nodes, the economic industry type and/or tax payment area of each node can be obtained through the parameters of each node. The nodes can be servers, enterprises, shops, legal booths and other enterprises and individual operators needing to handle business licenses.
In a specific implementation process, an enterprise needs to go to a business administration office to process a business license before conducting business, and in the process of processing the business license, the items that the enterprise needs to register include: enterprise name, enterprise address, enterprise responsible person, registered fund amount, economic components, operation range, operation mode, working personnel number, operation period and the like. In a finance and tax application scene, according to the needs of the finance and tax scene, each enterprise can be subjected to fragment management according to different tax policies, and the tax policies are mainly divided according to economic industry types and/or tax payment areas. Therefore, when a business needs to join a block chain for unified management after handling a business license, the economic industry type and/or tax payment region of the business can be noted by means of parameter setting.
For example, a factory address registered by a food processing company is 5151 a Qingsong road outside the Qingpu industrial park of Shanghai, and when the food processing company joins a block chain, a parameter set according to the economic industry type is a parameter indicating food industry, and a parameter set according to the tax payment region is a parameter indicating Shanghai. The parameter of the node acquired by the block chain when the node is deployed is the food industry in Shanghai.
In a possible embodiment, the tax policy for one economic industry type is the same in different tax payment areas nationwide, so when a node belonging to the economic industry type joins the blockchain for management, the set parameter may be a parameter related to only the economic industry type, that is, the set parameter does not include a parameter related to the tax payment area, and the blockchain only acquires the parameter indicating the economic industry type for the node when acquiring the attribute information of the node. Or, when setting the parameter, the parameter related to the economic industry type and the tax payment region is set at the same time, but when acquiring the attribute information of the node, the blockchain acquires only the parameter indicating the economic industry type, and does not acquire the parameter indicating the tax payment region. In the embodiment of the present application, the setting mode of the parameters of the economic industry type with the same tax policy in different tax payment regions is not limited in the embodiment of the present application.
For example, if the tax standards of service industries are the same nationwide, then when a company of a service industry (e.g., a catering company for a capitalization) joins a blockchain, in one approach, the company only sets a parameter indicating that its economic industry type is a catering company in the service industry, and does not set a parameter indicating that its tax area is a capitalization. The blockchain can only acquire the catering company of which the economic industry type of the node is the service industry when acquiring the attribute information of the node. In another mode, the company sets parameters for indicating the economic industry type (catering company in the service industry) and indicating the tax payment area (Chengdu) at the same time, but the block chain only acquires the catering company of which the economic industry type of the node is the service industry when acquiring the attribute information of the company.
In a possible implementation manner, in the same tax payment area, the tax policies for different economic industry types are the same, so when a node belonging to the tax payment area joins the block chain for management, the set parameter may be a parameter related to only the tax payment area, that is, the set parameter does not include a parameter related to the economic industry type, and at this time, the block chain can only obtain a parameter indicating the tax payment area by the node when obtaining the attribute information of the node. Or the parameters related to the economic industry type and the tax payment area are set simultaneously when the parameters are set, but only the parameter for indicating the tax payment area is obtained when the block chain obtains the attribute information of the node, and the parameter for indicating the economic industry type is not obtained. In the embodiment of the present application, the setting method of the parameters of the tax payment areas having the same tax policy in different economic industry types is not limited in the embodiment of the present application.
In one possible embodiment, the tax policies for different types of economic industries are different in the same tax payment area, and the tax policy for one type of economic industry is different in different tax payment areas nationwide, so when a node having different tax policies for different tax payment areas and different tax policies for other types of economic industries joins a block chain, the node needs to set parameters for indicating the types of economic industries and for indicating the tax payment areas at the same time. The block chain also needs to acquire the parameters of the node for indicating the economic industry type and for indicating the tax payment region at the same time when acquiring the attribute information of the node.
For example, if the tax policy of the transportation industry at the mansion gate is different from the tax policies of other tax payment areas, and different from the tax policies of other types of the economic industry at the mansion gate, then when a transportation enterprise at the mansion gate joins the block chain, it is necessary to set both the parameter indicating that the tax payment area is the mansion gate and the parameter indicating that the type of the economic industry is the transportation industry. When acquiring the attribute information of the enterprise, the blockchain also needs to acquire a parameter for indicating that the tax payment area is a building door and a parameter for indicating that the economic industry type is a transportation industry at the same time.
Step 102: and according to the attribute information of each node, fragmenting each node according to a preset fragmentation rule.
In the embodiment of the application, the blockchain fragments each node according to the acquired attribute information of each node through a preset fragmentation rule. The preset fragmentation rule refers to a fragmentation rule formulated according to a finance and tax service scene. At present, the number of nodes in China is about 3000 thousands, and the 3000 thousands of nodes are divided into 20 categories according to the types of economic industries. The 3000 ten thousand nodes are divided into 36 tax areas according to tax areas.
In one possible implementation, the fragmentation is based on the economic sector type of each node. And the block chain determines the nodes belonging to the same economic industry type from the acquired attribute information of each node, and divides the nodes belonging to the same economic industry type into the same piece. I.e. 3000 ten thousand nodes can be divided into 20 slices.
In one possible implementation, the sharding is based on the tax area of each node. And the block chain determines the nodes belonging to the same tax payment area from the acquired attribute information of each node, and divides the nodes belonging to the same tax payment area into the same piece. I.e. 3000 ten thousand nodes can be divided into 36 slices.
In one possible embodiment, the node attribute information obtained by the blockchain has only one parameter (i.e., a parameter indicating the economic industry type or a parameter indicating the tax payment region). When the tax policies for one economic industry type are the same in different tax payment areas nationwide, all nodes nationwide belonging to the economic industry type are divided into the same piece, and are not divided again according to the tax payment areas. When the tax policies aiming at different economic industry types are the same in the same tax payment area, all nodes belonging to the tax payment area are divided into the same piece.
For example, the tax policies of service industries nationwide are the same, and the parameters of the node attribute information acquired by the blockchain are only parameters indicating the economic industry type, so that all nodes belonging to the service industries are divided into the same piece by the blockchain and then are not divided again based on tax payment areas. For another example, in the tax payment region of tibetan, all the economic industry types have the same tax policy, and the parameter of the node attribute information obtained by the blockchain is only the parameter indicating the tax payment region, so that the blockchain does not perform the re-partition based on the economic industry types after dividing all the nodes belonging to the tibetan into the same piece.
In another possible implementation manner, the parameters of the node attribute information obtained by the block chain include both the economic industry type and the tax payment area, and then the block chain divides N nodes belonging to the same economic industry type into the same piece according to the economic industry type of each node. Then, from the N nodes of the piece, according to the tax payment area, the M nodes belonging to the same tax payment area are divided into the same sub-piece, namely, the piece belonging to the same economic industry type can be divided into 36 sub-pieces at most. Or the block chain divides N nodes belonging to the same tax payment area into the same piece according to the tax payment area of each node. Then, from the N nodes of the piece, according to the economic industry type, the M nodes belonging to the same economic industry type are divided into the same sub-piece, namely, the piece belonging to the same tax payment area can be divided into at most 20 sub-pieces.
For example, the tax policies of the real estate industry are different in each tax area, and the tax policies of the real estate industry are different in the same tax area as other types of economic industry. Then, the parameters of the attribute information of the nodes acquired by the blockchain include both the economic industry type and the tax payment area, and then the blockchain divides N nodes belonging to the real estate industry in each node into the same piece, and then divides M nodes belonging to the same tax payment area (for example, beijing) from the N nodes into one sub-piece. Or the block chain divides N nodes belonging to the Beijing area in each node into the same piece, and then divides M nodes belonging to the same economic industry type into one sub-piece from the N nodes. Wherein, the node of the sub-film management is all real estate enterprises in Beijing.
Specifically, after the nodes belonging to the same economic industry type are determined, the number of the nodes corresponding to each economic industry type can be obtained, and the economic industry type corresponding to the number of the nodes exceeding a first preset value is determined as the first economic industry type. All nodes in the first economic industry type that belong to the same economic industry subtype are then divided into the same piece.
For example, the number of nodes belonging to the service industry, which are determined by the blockchain according to the industry economic type from all the nodes, exceeds a first preset value (e.g., 10000). At this time, the blockchain divides all nodes belonging to the service industry into sub-types according to the economic industry (such as the catering industry, the hotel industry, the travel industry and the like), and divides nodes belonging to the same economic industry sub-type into the same piece.
In a possible implementation mode, the finance and taxation blockchain multi-chain system comprises P blockchains, different blockchains correspond to different functions, and the slicing results of each blockchain are synchronous. In the embodiment of the application, taking the fiscal and taxation block chain multi-chain system as an example, the article circulation chain, the fund settlement chain and the tax invoice chain are segmented according to the economic industry type and/or tax payment region, and then the segmented results in each chain of the article circulation chain, the fund settlement chain and the tax invoice chain are synchronized. For example, the real estate industry in Beijing was determined to be a sub-sheet that included 7000 businesses (i.e., 7000 nodes). There is a sub-slice of the real estate industry in Beijing in the goods circulation chain, the funds settlement chain, and the tax invoice chain, and the 7000 businesses are included in the sub-slice in each chain.
In a specific implementation process, a tax policy (which can also be called as a tax standard) is marked for each different piece through an intelligent contract, and when a transaction is carried out between two nodes and a fund settlement and invoicing function is triggered, the block chain takes the fund settlement transaction and the commodity circulation transaction as consumed input states and invoices are made at nodes corresponding to the tax invoice chain.
In the embodiment of the application, the finance and tax service scene is combined, and the segmentation is carried out according to the economic industry type and the tax payment region, so that the possibility of cross-segment transaction in the circulation of the goods can be reduced, the cross-segment communication is reduced, and the efficiency of a finance and tax block chain multi-chain system is effectively improved.
Based on the same inventive concept, the embodiment of the present application provides a block chain fragmentation device, which can implement the corresponding function of the block chain fragmentation method. The blockchain slicing apparatus may be a hardware structure, a software module, or a hardware structure plus a software module. The block chain slicing device can be realized by a chip system, and the chip system can be formed by a chip and can also comprise the chip and other discrete devices. Referring to fig. 2, the blockchain slicing apparatus includes an obtaining module 201 and a processing module 202. Wherein:

and determining that the nodes belonging to the same economic industry type are divided into the same piece.
In a possible implementation manner, the processing module 202 is specifically configured to:
