Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The business data processing method based on the block chain can be applied to an application environment shown in fig. 1. The application environment includes a server cluster 104 formed by a plurality of servers and a terminal 102, and the plurality of terminals 102 may be plural. Each server in the cluster of servers may act as a compute node. The server cluster may be a computing cluster. A blockchain system 106 is deployed in the computing cluster. The terminal 102 is connected to each server in the server cluster 104 via a network, the servers are connected via the network, and the servers are connected via the network to the blockchain system 106. The server acquires a block chain service calling request sent by the terminal, wherein the block chain service calling request carries service data and a scene identifier, and the service data comprises the block chain identifier. The server invokes the pre-configured blockchain service according to the blockchain service invocation request. The server acquires a first configuration file according to a pre-configured blockchain service, wherein a plurality of scene identifications and data processing strategies corresponding to each scene identification are recorded in the first configuration file. And the server determines a data processing strategy corresponding to the scene identifier in the first configuration file according to the pre-configured blockchain service. And the server calculates the service data according to the data processing strategy to obtain the data block containing the block chain identifier. The server stores the data block into a blockchain database corresponding to the blockchain identifier. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, among others. The server may be implemented as a stand-alone server or as a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a method for processing service data based on a blockchain is provided, and the method is applied to each server in the server cluster in fig. 1, and each server is used as a computing node in the computing cluster, and includes the following steps:
step 202, a blockchain invoking request is obtained, wherein the blockchain invoking request carries service data and a scene identifier, and the service data comprises the blockchain identifier.
The server acquires a block chain service call request sent by the terminal, and analyzes the block chain service call request to obtain service data and scene identification. For example, the business data may be transaction data. The traffic data may include a blockchain identification. The blockchain identifier is used for marking and analyzing that the obtained service data belongs to the blockchain corresponding to the blockchain identifier. The computing clusters have a blockchain system pre-deployed therein. The blockchain system is a carrier and organization method for running blockchain technology, and can be specifically a blockchain cluster formed by a plurality of servers. Blockchain technology is an internet database technology that utilizes a blockchain data structure to verify and store data, a distributed node consensus algorithm to generate and update data, a cryptography way to ensure the security of data transmission and access, and an intelligent contract consisting of automated script code to program and manipulate data. In this embodiment, the blockchain system may be a federated chain system. At least two blockchains may be included in the blockchain system. Multiple blockchains in a blockchain system may be at the same level, being a multi-chain blockchain structure. When the blockchain processes the service data, an identification field, namely a blockchain identification, needs to be added in a data structure of the multi-chain blockchain to mark which chain the service data belongs to. For example, an identification field may be added as chain. The conventional blockchain data structure may be compared to a blockchain multi-chain data structure as shown in fig. 3. The blockchain multi-chain data structure adds an identification field and corresponding field values chain=1 and chain=3.
The scene identification is used to mark the specific scene to which the blockchain service applies. For example, the scene identification may include a scene identification of a forensic scene and a scene identification of an intelligent contract scene. Wherein the deposit certificate is a general ledger that records all historical transactions. An intelligent contract is a computer protocol in which the contract is propagated, verified, or executed in an informative manner. When the scene identifier is the scene identifier of the evidence-storing scene, the service data is required to be stored. At this time, the service data may be referred to as to-be-authenticated data. According to different evidence-storing scenes, corresponding data to be stored are different. For example, in a transaction scenario, the to-be-authenticated data may be transaction data, such as an electronic invoice, etc.; in a judicial scene, the data to be authenticated may be judicial data, such as copyright evidence, etc. When the scene identifier is the scene identifier of the intelligent contract scene, the scene identifier indicates that formal verification of the service data is needed, and automatic execution of the transaction is realized.
Step 204, invoking the pre-configured blockchain service according to the blockchain service invocation request.
The computing clusters are pre-configured with blockchain services. When a server in the computing cluster acquires a block chain service calling request sent by a terminal, a preset block chain service is called according to the block chain service calling request. The preset configured blockchain service can provide corresponding blockchain scenes for different groups, namely, a plurality of groups can share one preset configured blockchain service. Each group may correspond to a blockchain, and the server may maintain blockchains corresponding to multiple groups. Group members in each group can send a block chain service calling request to a server through a terminal, and the server analyzes the block chain service calling request to obtain service data. The server then invokes the pre-configured blockchain service according to the blockchain identification in the business data, and further calculates the business data according to the pre-configured blockchain service.
Step 206, obtaining a first configuration file according to the pre-configured blockchain service, wherein a plurality of scene identifications and data processing strategies corresponding to each scene identification are recorded in the first configuration file.
Step 208, determining a data processing strategy corresponding to the scene identifier in the first configuration file according to the pre-configured blockchain service.
Step 210, calculating the service data according to the data processing strategy to obtain the data block containing the block chain identifier.
Step 212, the data block is stored in the blockchain database corresponding to the blockchain identifier.
The method comprises the steps that a first configuration file corresponding to scene identifiers is pre-configured in a computing cluster, and a plurality of scene identifiers and data processing strategies corresponding to the scene identifiers are recorded in the first configuration file. The data processing policy may be a consensus algorithm or the like. The server determines a data processing strategy corresponding to the scene identifier in the first configuration file according to the pre-configured blockchain service, further performs consensus verification on the service data according to the corresponding data processing strategy, and after the consensus verification is passed, the computing node calculates the consensus service data to obtain a data block corresponding to the scene identifier and containing the blockchain identifier.
A data block is a container data structure that is contained in a block ledger that aggregates data to be authenticated. The block ledger is a carrier for recording the data to be authenticated generated for a period of time, and records the information of a plurality of data blocks. The data to be authenticated may be data that needs to be stored into the blockchain. The plurality of data chunks may be concatenated in the chunk ledger in a temporal order of chunk generation. The data block includes a block header and a block body. Wherein the block header records the time stamp of the previous sequential block and the time stamp of the current data block. The server links the data blocks in time sequence to form a blockchain.
In one embodiment, when receiving a blockchain service call request sent by a terminal corresponding to different groups, the blockchain service call request is parsed to obtain a plurality of blockchain identifications. And the server calculates the service data through a data processing strategy corresponding to the scene identifier, so that parallel calculation among a plurality of blockchains is realized. The server calculates the service data through the calculation nodes of different block chains, and a data block corresponding to each block chain can be obtained, so that corresponding block chains are generated according to the block chain identifications in the data blocks.
A blockchain database corresponding to the blockchain identification is pre-created in the server. The blockchain database is created from the blockchains that were successfully registered. After the server generates the data block, the data block may be stored in a blockchain database corresponding to the blockchain identifier.
In one embodiment, the terminal that sent the service invocation request may also be validated before invoking the pre-configured blockchain service according to the blockchain service invocation request. Specifically, the server acquires corresponding verification information according to the terminal identifier of the terminal, and verifies the validity of the terminal according to the verification information. And after the validity verification is passed, calculating the service data according to the data processing strategy corresponding to the scene identifier. Thereby ensuring the security of the blockchain service.
In this embodiment, a blockchain service invocation request is obtained, where the blockchain service invocation request carries service data and a scene identifier, and the service data includes the blockchain identifier. Invoking a pre-configured blockchain service according to the blockchain service invocation request. The method comprises the steps of obtaining a first configuration file according to a preset blockchain service, determining a data processing strategy corresponding to a scene identifier in the first configuration file, and calculating service data according to the data processing strategy. The pre-configured blockchain service determines a data processing strategy through the scene identification, can provide corresponding scene services for different groups, realizes sharing of one set of blockchain service among a plurality of groups, and effectively reduces the maintenance cost of a blockchain system. The data blocks obtained through calculation are stored in the block chain database corresponding to the block chain identification, so that the data blocks belonging to different block chains can be better isolated, the data blocks of different block chains are not required to be stored in the same database, and the data security of the block chain is further improved.
In one embodiment, as shown in fig. 4, the method further includes: calculating the service data according to a data processing strategy to obtain a data block containing a block chain identifier, which specifically comprises the following steps:
step 402, obtaining a second configuration file according to the pre-configured blockchain service, wherein a plurality of blockchain identifiers and a plurality of computing node identifiers corresponding to each blockchain identifier are recorded in the configuration file.
And step 404, sending the service data to the computing nodes corresponding to the other computing node identifiers according to the pre-configured blockchain service, so that the computing nodes corresponding to the other computing node identifiers can perform consensus on the service data according to the data processing strategy.
And step 406, receiving the service data after consensus returned by the corresponding computing node of the other computing node identifiers.
Step 408, the service data after consensus is calculated according to the pre-configured blockchain service, so as to obtain a data block containing the blockchain identifier.
The computing cluster is pre-configured with a second configuration file, and a plurality of blockchain identifiers and computing node identifiers corresponding to the blockchain identifiers are recorded in the second configuration file. The blockchain identification may correspond to a group identification. The computing node identity corresponding to each blockchain identity may correspond to a group member identity in the group identity. The server may thereby determine a plurality of compute node identifications corresponding to the blockchain identifications in the second configuration file according to the preconfigured blockchain service. The server serves as one computing node in the blockchain identifier, and a corresponding computing node identifier exists. The server can send the service data obtained by analysis to the computing nodes of other computing node identifiers corresponding to the blockchain identifier according to the preconfigured blockchain service. And the computing nodes corresponding to the other computing node identifiers perform consensus verification on the acquired service data, obtain the service data after the consensus verification is passed, and return the service data after the consensus to the server. The server further calculates the service data after consensus according to the pre-configured block chain service to obtain a data block. The data block includes a blockchain identification.
In one embodiment, each compute node of a blockchain may include a plurality of containers peer, contract, consesus, storage or the like. The peer container is used as a carrier of the account book and the intelligent contract, is a basic node in the blockchain network and is mainly responsible for executing chain codes to realize the reading and writing operation of the account book. The contact container is used to execute a smart contract. The Conssess container is used for carrying out consensus processing on the business data. The storage container is used for storing business data. In the process of processing service data through the block chain, different computing nodes perform consensus on the service data through the data processing strategies corresponding to each container, and the transaction execution results after consensus are stored in the blocks to obtain the data blocks. The data block comprises a block chain identification, a transaction execution result after consensus and service data corresponding to the computing node.
For example, two chains are running in the current blockchain, chain=service and chain=finish, and when a blockchain service call request is acquired, the blockchain service call request is parsed to obtain service data, where the service data includes a blockchain identifier chain=service. And the server determines a plurality of computing node identifications corresponding to the chain=service in the second configuration file according to the blockchain service call request. And sending the service data to the computing nodes corresponding to the other computing node identifiers according to the pre-configured blockchain service, so that the computing nodes corresponding to the other computing node identifiers perform consensus on the service data, and receiving the service data after consensus returned by the computing nodes corresponding to the other computing node identifiers. And calculating the business data after consensus according to the pre-configured blockchain service to obtain a data block containing the blockchain identifier. A field chain in block header information (BlockHeader) in a data block is shown as a service. Since the data Block (Block) is composed of a Block header (BlockHeader) and a Block body (BlockData), as long as the Block header contains the chain information, the data Block also contains the corresponding chain information, i.e. contains the blockchain identifier.
In one embodiment, the current blockchain may be run with multiple blockchains, each blockchain corresponding to a group identifier, where the group identifier includes multiple group member identifiers. Group members of multiple groups may share a set of blockchain services. When a blockchain service invocation request of group members in a plurality of different groups is acquired, the blockchain service invocation request can be processed in parallel.

Business data corresponding to different blockchain identifiers are input into the peer container, and corresponding account books are read and written according to the business data. And judging whether the blockchain corresponding to the blockchain identifier is expired, deleting the data block corresponding to the blockchain when the blockchain is expired, and returning to an initial state. When the blockchain is not expired, invoking a preconfigured blockchain service according to the blockchain service invoking request, inputting service data into a contact container through the preconfigured blockchain service to execute an intelligent contract, inputting the service data into a contacts container to perform consensus processing on the service data, and inputting the service data after the consensus processing into a storage container to generate a data block containing a blockchain identifier. And further storing the data blocks into a block chain database corresponding to the corresponding block chain identifications. FIG. 5 is a flow diagram illustrating sharing of a set of blockchain services among different groups in one embodiment. Two populations, client1, with a population member A, B, C and client2, with a population member X, Y, Z, are included in FIG. 5. The blockchain corresponding to the group client1 is chain= kst, and the blockchain corresponding to the group client2 is chain= kyc.

Configuring entitlement policies may include how blockchains join new group members, how compute node generation parameters are changed, how intelligent contract policies are executed, and so on. The server performs validity verification on the registration information, and after verification is passed, the registration information is configured to obtain configuration information. The configuration information comprises configured group member information, configured computing node information, configured intelligent contract information and configured configuration authority policies.

And the server deploys the intelligent contract information obtained by analysis to the configured computing nodes. Further, the configuration authority policy obtained through analysis is deployed to the configured computing node added with the intelligent contract information. The server further generates a blockchain corresponding to each blockchain registration request according to the configuration information, and archives the registration information.
In this embodiment, the registration information is configured by performing validity verification on the registration information, and after the registration information passes the validity verification, configuration information is obtained, and then a blockchain corresponding to the blockchain registration request is generated according to the configuration information. And the method is beneficial to the subsequent group members to call the corresponding blockchains to process the service data.
