Detailed Description
The embodiments of the present application will be described below with reference to the drawings.
With the rapid development of internet technology, in order to realize fairness of transactions, various industries and fields gradually form a transaction system which is supervised by a third-party management mechanism or a hardware facility. However, the third party authority may have a trust issue, for example, when the third party authority is biased toward one party of the transaction, the transaction process may be unfair. Therefore, the Block Chain (BC) technology becomes a hot topic of research by virtue of the advantages of decentralization, distributed ledger storage, high fairness and the like.
The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The blockchain is essentially a decentralized database, which is a string of data blocks associated by using cryptography, each data block contains information of a batch of network transactions, and the information is used for verifying the validity (anti-counterfeiting) of the information and generating the next block. The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer.
The block chain underlying platform can comprise processing modules such as user management, basic service, intelligent contract and operation monitoring. The user management module is responsible for identity information management of all blockchain participants, and comprises public and private key generation maintenance (account management), key management, user real identity and blockchain address corresponding relation maintenance (authority management) and the like, and under the authorization condition, the user management module supervises and audits the transaction condition of certain real identities and provides rule configuration (wind control audit) of risk control; the basic service module is deployed on all block chain node equipment and used for verifying the validity of the service request, recording the service request to storage after consensus on the valid request is completed, for a new service request, the basic service firstly performs interface adaptation analysis and authentication processing (interface adaptation), then encrypts service information (consensus management) through a consensus algorithm, transmits the service information to a shared account (network communication) completely and consistently after encryption, and performs recording and storage; the intelligent contract module is responsible for registering and issuing contracts, triggering the contracts and executing the contracts, developers can define contract logics through a certain programming language, issue the contract logics to a block chain (contract registration), call keys or other event triggering and executing according to the logics of contract clauses, complete the contract logics and simultaneously provide the function of upgrading and canceling the contracts; the operation monitoring module is mainly responsible for deployment, configuration modification, contract setting, cloud adaptation in the product release process and visual output of real-time states in product operation, such as: alarm, monitoring network conditions, monitoring node equipment health status, and the like.
The blockchain network comprises at least one blockchain node device, and the blockchain node device can be any computer device accessed into the blockchain network, such as a server, a user terminal, and the like. Each blockchain node device can receive input information when performing normal operation, and maintain shared data of the blockchain network based on the received input information. In order to ensure information intercommunication among the block link point devices, information connection may exist among each block link point device in the block chain network, and information transmission may be performed among the block link point devices through the information connection. For example, when any blockchain node device in the blockchain network receives input information, other blockchain node devices in the blockchain network acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored in all blockchain node devices in the blockchain network are consistent.
Referring to fig. 1, fig. 1 is a schematic diagram of an architecture of a data transmission system according to an embodiment of the present application. The block chain network is composed of a plurality of block chain node devices that can communicate with each other, for example, a block chain network composed of a block chain node device 101, a block chain node device 102, a block chain node device 103, and a block chain node device 104. Each block chain node device stores one same block chain, each block chain is composed of a plurality of blocks, each block comprises a hash value (hash value of the block) of the block storage transaction record and a hash value of the previous block, and the blocks are connected through the hash values to form the block chain. The block also includes information such as a time stamp at the time of block generation. The blocks in the block chain are connected together in the order of block generation time. For example, the blockchain 105 is formed by blocks 1, 2, 3, 4, 5, and 6, which are consecutive to each other in the time sequence of generating the blocks. For example, block 2 is generated after block 1, so block 2 includes the hash value of block 1, and block 2 is connected after block 1.
Currently, a user acquires data stored in a blockchain network by directly accessing a resource pool through an interface, and therefore, different interfaces store different programs for executing different functions. For example, if the function of interface a is to access a target block in a block chain, interface a stores the block height of the target block. For another example, if the function of the interface B is to transmit target data, the interface B stores a program related to the transmission of the target data. Wherein, the interface A and the interface B are different interfaces.
In order to increase the utilization rate of the interface and improve the development efficiency, the application provides a data transmission method which can be applied to block link node equipment. The block link node device is configured with a service logic layer, a resource pool, and at least one interface, and the data transmission method may include: receiving a data request sent by any interface in at least one interface through a service logic layer; determining a service rule corresponding to the data request through a service logic layer; processing the data request based on the service rule through the service logic layer to obtain a processing result; the resource pool is accessed by the business logic layer based on the processing result.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a block link point device according to an embodiment of the present disclosure. The block link node equipment is configured with a service logic layer, a resource pool and at least one interface. The interface is used for data type conversion, for example, the interface can convert the acquired data of the integer type into data of the floating point type. The resource pool is used for storing data written into the block chain. Such as the time of the transaction, the contents of the transaction, and information about both parties to the transaction, etc. The service logic layer is used for processing the data request and accessing the resource pool, wherein the service logic layer is integrated with a function of executing the data transmission method provided by the application. Specifically, the interface may send the data request to the service logic layer, the service logic layer obtains a processing result after performing the data processing provided by the present application, and the service logic layer accesses the resource pool based on the processing result.
Therefore, in the embodiment of the application, a service logic layer is added in the block link node device, the related program of the data transmission method provided by the application is integrated in the service logic layer, and correspondingly, the interface is used for performing a data type conversion function on data. Compared with the method that programs for executing different data processing functions are stored in each interface, the code amount in the interface can be reduced, and the development efficiency can be improved.
Based on the schematic structure of the block link point device shown in fig. 2. Referring to fig. 3, fig. 3 is a schematic flow chart of a data transmission method according to an embodiment of the present application, where the data transmission method may include, but is not limited to, the following steps:
step S301: and receiving a data request sent by any interface in the at least one interface through the service logic layer.
The data request is used for requesting specific data from the resource pool, or for requesting functions such as processing of transmitted data. Because the purpose of the data request is different, the information carried by the data request is different. For example, the data request is used to query a target block in the target block chain according to the block height, and the information carried by the data request is the block height of the target block.
Specifically, the block link node device is configured with at least one interface, wherein any interface can perform an action of sending a data request to the service logic layer. Correspondingly, after the service logic layer receives the data request, the service logic layer can process the data request and return the data requested by the data request to the interface corresponding to the data request, thereby completing the data transmission process.
The interface may obtain the data request in various ways. Optionally, the interface may receive an acquisition request sent by the user side, and the interface generates a data request according to the acquisition request. For example, the acquisition request is information for determining a target block in the target block chain according to the height of the target block. Optionally, the interface may generate the data request when detecting the user operation. For example, the interface can detect a click operation of a user on the display screen and generate a corresponding data request according to the click operation.
In one implementation, the interface may perform data conversion processing on the acquired acquisition request, and generate a data request according to the acquisition request. For example, the acquisition request acquired by the interface includes the a information and the data format of the a information, and it is understood that the data format of the a information received by the interface is not all the data format meeting the requirements of channel transmission or a service logic layer, and therefore, after the interface receives the data format of the a information, the data format of the a information may be converted into a data type, so as to facilitate subsequent processing of the a information. For example, the data format of the information a received by the interface is a low byte, and if the data processed by the service logic layer is a high byte, the interface may convert the data format of the information a into a high byte data format corresponding to the information a, so as to facilitate subsequent processing by the service logic layer.
As can be seen, the interface performs a function of converting the data format, and the amount of code stored by the interface is reduced as compared with a function in which the interface performs data processing.
Step S302: and determining a business rule corresponding to the data request through a business logic layer.
Business rules are created, updated and debugged in real time by business personnel. A business rule may be understood as a flow of a business, or a processing logic of a data item. For example, the method for generating the service rule definition index includes: the index A is obtained by adding the index B and the index C.
Specifically, the data request may include the logical requirements of the data request in addition to the data format of the data. For example, the logic requirement is to query information of a target block in the target block chain, and the like, and therefore, the service logic layer can determine, based on the data request, that the service rule corresponding to the data request is to query information of the target block in the target block chain.
Step S303: and processing the data request through the service logic layer based on the service rule to obtain a processing result.
In one implementation, the data request may indicate information of the query target block, the data request including a height of the target block. Wherein the height of the block is the number of blocks on the block chain. Therefore, the process of obtaining the processing result by processing the data request based on the service rule through the service logic layer can be understood as follows: and determining the identification of the target block based on the height of the target block through the service logic layer, wherein the processing result is the identification of the target block.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a block chain according to the present application. As shown in fig. 4, the block chain is composed of 466 blocks, wherein the starting block 401 includes a block header and a block body, the block header stores characteristic values, version numbers, time stamps, and difficulty values of the input information, and the block body stores the input information. The next block of the starting block 401 takes the starting block 401 as a parent block, the next block also includes a block header and a block main body, the block header stores the input information characteristic value of the current block, the block header characteristic value of the parent block, the version number, the timestamp and the difficulty value, and so on, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the security of the input information in the block is ensured. The height of the starting block 401 is 0, the block height of the next block of the starting block is 1, and so on, and each block has a corresponding block height. Therefore, the corresponding block and the block identifier can be searched according to the block height.
In another implementation, the data request may indicate information to query the target transaction data, the data request including a hash of the target transaction data. Therefore, the process of obtaining the processing result by processing the data request based on the service rule through the service logic layer can be understood as follows: and determining the address information of the target transaction data based on the Hash through the service logic layer, wherein the processing result is the address information of the target transaction data. Specifically, when the block link point device processes the target transaction data, a hash is generated, and the hash has an association relationship with the target transaction data. Therefore, the address information of the target transaction data can be determined according to the hash, and the information of the occurrence time, the transaction state and the like of the target transaction data can be further obtained.
For example, the first block link point device and the second block link point device belong to the same block chain network, the first block link point device obtains address information of the target transaction data according to the hash of the target transaction data, and the address information points to the second block link point device, so that the first block link point device can obtain information of the target transaction data from the second block link point device.
Step S304: the resource pool is accessed by the business logic layer based on the processing result.
The resource pool is used for performing functions of operations such as storage and query of data. The resource pool stores at least one item of data resource, and when there is a data request, the resource pool can allocate the corresponding data resource according to the data request, and give a busy identifier to the data resource, which is used to indicate that the data resource is occupied. When the data resource is used up, the resource pool clears the busy mark of the data resource to indicate that the data resource can be used in the next request.
In one implementation, the data request indicates information of the query target block, the data request includes the height of the target block, and the processing result is the identification of the target block. Accordingly, a method for accessing a resource pool based on a processing result through a business logic layer may include: and accessing the target block indicated by the identification of the target block in the resource pool through the service logic layer to obtain the information of the target block.
In another implementation, the data request indicates information for querying the target transaction data, the data request includes a hash of the target transaction data, and the processing result is address information of the target transaction data. Correspondingly, the method for accessing the resource pool based on the processing result through the business logic layer may include: and accessing the resource pool through the service logic layer based on the address information of the target transaction data to obtain the information of the target transaction data.
Therefore, in the data transmission method provided by the embodiment of the application, the interface has a function of data conversion, and the service logic layer is responsible for processing the data request, so that compared with a method that the interface stores a set of complete data processing program, the code amount of the interface is greatly reduced, and the development efficiency is improved.
Referring to fig. 5, fig. 5 is a schematic flow chart of another data transmission method according to an embodiment of the present application, where the method includes, but is not limited to, the following steps:
step S501: and receiving the data request sent by the interface through the service logic layer.
Step S502: and checking the data request through the service logic layer.
It is understood that the data request sent by the interface to the service logic layer may include various data formats, and the data format of the data request processed by the service logic layer is constant. That is, the data request includes a data format that the business logic layer performs subsequent related steps only if the specifications of the business logic layer are satisfied. Therefore, the service logic layer checks the data request, and if the check is successful, the subsequent steps are executed. For example, the service logic layer only processes the data request in the format a, and if the format of the data request sent by the interface is B, the service logic layer cannot process the data request in the format B.
In an implementation manner, the manner of checking the data request by the service logic layer may be: comparing the data type of the data request with the data type corresponding to the interface stored in the service logic layer through the service logic layer; and if the data type of the data request is the same as the data type corresponding to the interface stored in the service logic layer, the data request is determined to be successfully verified through the service logic layer. For example, if the data type of the data request sent by the interface is integer, and the data type corresponding to the interface stored in the service logic layer is character string type, the data type of the data request sent by the interface may be determined, and if the data type is different from the data type corresponding to the interface stored in the service logic layer, the service logic layer determines that the verification of the data request fails.
In another implementation manner, the manner in which the service logic layer checks the data request may be: judging whether the service field of the data requested by the data request is the service field corresponding to the block link point equipment or not through the service logic layer; and if the service field of the data requested by the data request is the service field corresponding to the block link point equipment, determining that the data request is successfully verified through the service logic layer. For example, the business field corresponding to the block link point device is an educational field, and if the business field of the data requested by the data request is a financial field, the business logic layer may determine that the verification for the data request fails.
Step S503: and determining a business rule corresponding to the data request through a business logic layer.
Step S504: and processing the data request through the service logic layer based on the service rule to obtain a processing result.
Step S505: the resource pool is accessed by the business logic layer based on the processing result.
It should be noted that the implementation process of step 501 is similar to that of step S301, and the implementation processes of step S503 to step S505 are similar to that of step S202 to step S204, which is not described herein again in this embodiment of the present application.
Therefore, according to the embodiment of the application, before the service logic layer determines the service rule according to the data request, the data request is checked, and the subsequent operation is executed under the condition that the check is successful, so that the data request processed by the block chain node equipment can be ensured to be the data request allowed by the block chain node equipment, and the data transmission efficiency is improved. Compared with the program with different functions respectively stored in each interface, the program for processing the integrated data of the business logic layer reduces the code amount and improves the development efficiency.
