It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The service data processing method based on the block chain can be applied to the application environment shown in fig. 1. The application environment includes a server cluster 104 composed of a terminal 102 and a plurality of servers, and the terminal 102 may be a plurality. Each server in the server cluster may act as a compute node. The server cluster may act as a compute cluster. A blockchain system 106 is deployed in the computing cluster. The terminal 102 and each server in the server cluster 104 are connected through a network, the servers are connected through a network, and the servers are connected with the blockchain system 106 through a network. The server obtains a block chain service call request sent by the terminal, wherein the block chain service call request carries service data and a scene identifier, and the service data comprises the block chain identifier. And the server calls the pre-configured blockchain service according to the blockchain service calling request. The server acquires a first configuration file according to a pre-configured blockchain service, wherein a plurality of scene identifiers and a data processing strategy corresponding to each scene identifier 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 a data block containing the block chain identifier. And the server stores the data blocks into a block chain database corresponding to the block chain identification. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server may be implemented as a stand-alone server or as a server cluster consisting of a plurality of servers.
In an embodiment, as shown in fig. 2, a method for processing service data based on a blockchain is provided, which is described by taking the method as an example applied to each server in a server cluster in fig. 1, where each server is used as a computing node in a computing cluster, and includes the following steps:
The server obtains a block chain service call request sent by the terminal, and analyzes the block chain service call request to obtain service data and a scene identifier. For example, the business data may be transaction data. The traffic data may include a blockchain identification. The block chain identifier is used for marking that the service data obtained by analysis belongs to the block chain corresponding to the block chain identifier. The block chain system is pre-deployed in the computing cluster. The blockchain system is a carrier and an organization mode for running a blockchain technology, and specifically may be a blockchain cluster formed by a plurality of servers. The blockchain technology is an internet database technology that verifies and stores data using a blockchain data structure, generates and updates data using a distributed node consensus algorithm, secures data transmission and access using a cryptographic manner, and programs and manipulates data using an intelligent contract consisting of automated script codes. In this embodiment, the blockchain system may be a federation chain system. At least two blockchains may be included in the blockchain system. The block chains in the block chain system may be at the same level, and have a multi-chain block chain structure. When the block chain processes the service data, an identification field, that is, a block chain identifier, needs to be added to the data structure of the multi-chain block chain 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 scenario identification may include a scenario identification of a warranty scenario and a scenario identification of a smart contract scenario. Wherein the evidence is a general ledger for collecting all historical transactions. An intelligent contract is a computer agreement to propagate, validate or execute contracts in an informational manner. And when the scene identifier is the scene identifier of the evidence storage scene, the service data is required to be stored. At this time, the service data may be referred to as the data to be certified. According to different evidence storing scenes, the corresponding data to be stored with the evidence are different. For example, in a transaction scenario, the data to be certified may be transaction data, such as an electronic invoice; in a judicial scene, the data to be stored can be judicial data, such as copyright evidence and the like. When the scene identification is the scene identification of the intelligent contract scene, the business data needs to be formally verified, and the transaction is automatically executed.

When a server in the computing cluster acquires a block chain service call request sent by a terminal, a block chain service configured in advance is called according to the block chain service call request. The preset configured blockchain service can provide corresponding blockchain scenes for different groups, that is, a plurality of groups can share a set of pre-configured blockchain service. Each group may correspond to a blockchain, and the server may maintain blockchains corresponding to a plurality of groups. Group members in each group can send a block chain service call request to the server through the terminal, and the server analyzes the block chain service call request to obtain service data. The server calls the pre-configured block chain service according to the block chain identification in the service data, and then calculates the service data according to the pre-configured block chain service.
A first configuration file corresponding to the scene identifier is pre-configured in the computing cluster, and a plurality of scene identifiers and data processing strategies corresponding to each scene identifier are recorded in the first configuration file. The data processing strategy 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 block chain service, performs consensus verification on the service data according to the corresponding data processing strategy, and calculates the consensus-verified service data by the calculating node after the consensus verification is passed, so as to obtain a data block corresponding to the scene identifier and containing the block chain identifier.
A data block is a container data structure that is contained in a block book with aggregated data to be deposited. The block book is a carrier for recording data to be stored and certified generated in a period of time, and records information of a plurality of data blocks. The data to be certified may be data that needs to be stored into the blockchain. A plurality of data chunks may be concatenated in the chunk book in chronological order of chunk generation. The data block includes a block header and a block body. Wherein, the block head records the time stamp of the previous sequential block and the time stamp of the current data block. The server connects the data blocks according to the time sequence to form a block chain.
In one embodiment, when receiving a blockchain service call request sent by terminals corresponding to different groups, the blockchain service call request is analyzed to obtain a plurality of blockchain identifiers. 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 block chains is realized. The server calculates the service data through the calculation nodes of different block chains, and can obtain the data block corresponding to each block chain, so that the corresponding block chain is generated according to the block chain identifier in the data block.
A block chain database corresponding to the block chain identifier is pre-established in the server. The blockchain database is created based on the blockchains that are successfully registered. After the server generates the data block, the server may store the data block in the blockchain database corresponding to the blockchain identifier.
In one embodiment, before the preconfigured blockchain service is called according to the blockchain service calling request, validity verification can be further performed on the terminal sending the service calling request. Specifically, the server obtains 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. And calling the pre-configured blockchain service according to the blockchain service calling request. And then, a first configuration file is obtained according to the pre-configured block chain service, a data processing strategy corresponding to the scene identifier is determined in the first configuration file, and then the business data is calculated according to the data processing strategy. The pre-configured block chain service determines a data processing strategy through the scene identifier, can provide corresponding scene services for different groups, realizes sharing of a set of block chain service among a plurality of groups, and effectively reduces the maintenance cost of a block chain system. The data blocks obtained through calculation are stored in the block chain database corresponding to the block chain identification, the data blocks belonging to different block chains can be better isolated, the data blocks of different block chains do not need to be stored in the same database, and the data security of the block chains is further improved.

The blockchain identification may correspond to a group identification. The computing node identifier corresponding to each blockchain identifier may correspond to a group member identifier in the group identifier. The server may thereby determine, in the second configuration file, a plurality of compute node identifiers corresponding to the blockchain identifiers according to the preconfigured blockchain service.

And the server further calculates the service data after the consensus according to the pre-configured block chain service to obtain a data block. The data block includes a block chain identifier.
In one embodiment, each compute node of a blockchain may include a plurality of containers such as peers, contacts, consesus, stores, and the like. The peer container is used as a carrier of the account book and the intelligent contract, is a basic node in a block chain network, and is mainly responsible for executing chain codes and realizing read-write operation on the account book. The contract container is used to execute intelligent contracts. The conseus container is used for performing consensus processing on the service data.
