In the conventional blockchain technology, in order to meet the storage requirement of blockchain nodes on a large amount of data in the course of running blockchain service, the blockchain nodes generally use a non-relational database with efficient access efficiency for data storage, however, the non-relational database is not favorable for data analysis due to lack of transaction relationship, lack of connection and non-standardization among data. The relational database has complete transaction relationship, data are linked and have strict standardized structure, if the non-relational database in the traditional block chain technology is replaced by the relational database, although the data analysis is facilitated, the direct use of the relational database in a block chain bottom layer system brings huge challenges to the online read-write performance in the block chain service process of block chain link point operation.

Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.
FIG. 1 is a flow chart of a method of maintaining blockchain data in accordance with an exemplary embodiment. The method is applied to node equipment with block chain nodes, wherein the node equipment maintains a block chain non-relational database and a block chain relational database, and the block chain non-relational database is used for maintaining block chain data generated when block chain service is operated by the block chain nodes; the method comprises the following steps:
s102: and acquiring the block chain data maintained in the block chain non-relational database.
Fig. 2 is a block diagram of a system architecture for maintaining blockchain data according to an exemplary embodiment. As shown in fig. 2, each blockchain node in the blockchain network is deployed on a corresponding node device, and each node device maintains a blockchain non-relational database and a blockchain relational database at the same time. In the embodiments of the present specification, the blockchain non-relational database belongs to the non-relational database, and the blockchain relational database belongs to the relational database.
On the one hand, the blockchain non-relational database is used as a native database of the blockchain link point-to-point operation blockchain service, namely, as a part of the basic architecture of the blockchain underlying system, and is used for efficiently accessing blockchain data generated in the process of the blockchain link point-to-point operation blockchain service. For example, the blockchain non-relational database may specifically adopt a Key-Value database (Key-Value pair database, a typical non-relational database, abbreviated as K-V database), which, unlike a relational database, does not explicitly store the values of data, and does not have the concept of schema (database schema information) in MySQL (relational database management system) and PostgreSQL (object-relational database management system which is a very well-characterized free software). This means that it cannot filter and Query the partial contents of the stored data by using Structured Query Language (SQL) with where as a relational database. If you do not know which query you want from, you need to go through all key values, find the corresponding value, filter it, and finally keep only the part of data you want. This is very computationally intensive and means that the K-V database can only guarantee high performance if the key is known, otherwise its performance is significantly insufficient. Thus, while K-V databases are superior to relational databases in terms of absolute access speed, the requirement to know the key value limits its application scenarios. Although the above description only refers to the introduction of K-V databases, it is essentially applicable to most non-relational databases, which in general have efficient access speed but lack data analysis capabilities, such as querying capabilities based on indexing, relationships between data.
In the embodiment of the present specification, since the node device deployed blockchain underlying system (including the blockchain link point and the corresponding blockchain database) follows a non-relational database (i.e., a blockchain non-relational database) with an efficient access speed, when the blockchain service is operated, the blockchain node can efficiently access data from the blockchain non-relational database, thereby ensuring efficient operation of the blockchain service.
On the other hand, the node device related to the embodiments of the present specification additionally maintains a blockchain relational database as a native database for providing data analysis services to users, that is, as a part of an infrastructure of a data analysis system, for providing data analysis services to analysis demanders. For example, the blockchain non-relational database may specifically adopt an oracle database, MySQL, or other relational databases. A relational database refers to a database that uses a relational model to organize data, and stores data in rows and columns for a user to understand conveniently, a series of rows and columns of the relational database are called tables, and a group of tables constitutes the database. A user retrieves data in a database by a query, which is an executable code that defines certain areas in the database. The relational model can be simply understood as a two-dimensional table model, a relational database is a data organization formed by two-dimensional tables and relations between the two-dimensional tables, the relational database needs to define database mode information such as the structure of the tables, the relation of the tables, a normalized data structure and the like in advance, and then stores data according to the database mode information, supports SQL (structured query language), has strong data analysis capability, but has poor efficiency once processing massive data because the relational database emphasizes the consistency of the data and pays huge cost for reducing the read-write performance, and the reliability of storing data and processing data of the relational database is good, and the performance is reduced particularly when high concurrent read-write is encountered. In general, the relational database has strong data analysis capability but has poor access speed and read-write performance, and is not suitable for large-scale concurrent read-write application scenarios.
In this embodiment of the present specification, since the data analysis system (including the data analysis engine and the corresponding database not shown in fig. 2) deployed under the node device chain employs a non-relational database (i.e., a blockchain relational database) with an efficient access speed, when the node device executes the data analysis service by invoking the data analysis engine, the node device can utilize a strong data analysis capability of the blockchain non-relational database, thereby ensuring that a convenient data analysis service is provided to an analysis demand party.
The data maintained in the blockchain relational database related to the embodiments of the present specification is obtained by data conversion and migration in the blockchain non-relational database. The following describes the data conversion and migration process.
In an embodiment of this specification, the acquiring the blockchain data maintained in the blockchain non-relational database includes: receiving the block chain data actively pushed by the block chain link point; and/or sending a block chain data request to the block chain nodes, and receiving the block chain data returned by the block chain nodes in response to the block chain data request.
The method for maintaining block chain data according to the embodiments of the present description is applied to a node device, and in particular, to a data conversion engine deployed under a node device chain. The node device may obtain the blockchain data maintained in the blockchain non-relational database in at least one of two ways, where the two ways include: firstly, by receiving actively pushed blockchain data of blockchain nodes, for example, each time when a blockchain node adds or modifies blockchain data to a blockchain non-relational database in the process of running blockchain service, a blockchain link node actively pushes a data update message carrying the newly added or modified blockchain data to a data conversion engine under a chain, and the method can timely convert and synchronize data in the blockchain non-relational database to the blockchain relational database, so that the symmetry and timeliness of the data in the blockchain relational database are ensured; secondly, the node device sends a block chain data request to the block chain nodes to acquire the block chain data returned by the block chain nodes in response to the block chain data request, and the method acquires the block chain data through a request-response mode, so that the range of the requested block chain data can be effectively controlled, and data which do not need to be maintained in a block chain relational database can be shielded.
Optionally, the sending a block chain data request to the block chain node includes: initiating the blockchain data request for the intelligent contract to maintain the blockchain data in the blockchain non-relational database to the intelligent contract deployed at the blockchain link point; or, initiating the blockchain data request to the blockchain link point for the blockchain data maintained in the blockchain non-relational database.
The blockchain data according to the embodiments of the present specification includes blockchain data, status data, and event data. The blockchain account book is a special data structure, which is formed by connecting a plurality of blocks end to end through a hash anchor and has non-tamper-resistance, each block consists of a block head and a block body, the block head of any block contains information such as a state tree root, a transaction number root, a receipt tree root, a block height and a hash value of a corresponding parent block of the block, and the block body contains transaction data (transaction hash) contained by the block. The block data referred to in the embodiments of the present specification refers to data included in a block chain directory. The state data and event data referred to in the embodiments of the present description are maintained by the respective smart contracts deployed at the block chain nodes (in essence, contract storage space corresponding to the respective smart contracts in the block chain non-relational database is maintained).
In one embodiment, a plurality of intelligent contracts are deployed at block chain nodes, and corresponding state data is maintained in any intelligent contract and is maintained in a contract storage space corresponding to any intelligent contract in a block chain non-relational database. And the node device may initiate a blockchain data request to the intelligent contracts deployed at the blockchain nodes (in fact, any intelligent contract is deployed at each blockchain node in the blockchain network), wherein the blockchain data request is in the form of a blockchain transaction, and after the blockchain transaction is received by the blockchain nodes, the blockchain nodes further call the intelligent contract indicated by the blockchain transaction to execute the blockchain transaction. When the intelligent contract is about to execute the blockchain transaction, blockchain data indicated by the blockchain transaction is searched and obtained from a contract storage space corresponding to the intelligent contract in the blockchain non-relational database, and the blockchain data is called back to the node equipment as a response message (such as in the form of a blockchain event) corresponding to the blockchain data request, so that the blockchain data maintained in the blockchain non-relational database is obtained in a mode of calling the intelligent contract.
In another embodiment, the node device may directly initiate a blockchain data request to the blockchain link point, for example, initiate a blockchain data request through a data query interface of the blockchain node, where the blockchain data request is used for the blockchain link point to retrieve the blockchain data indicated by the blockchain data request from the blockchain non-relational database and call back to the node device.
In yet another embodiment, the node device may initiate the blockchain data request directly to the blockchain non-relational database, for example, by initiating the blockchain data request through a database interface of the blockchain non-relational database, which corresponds to a local call under the node device chain without passing through the blockchain node, and the blockchain non-relational database returns the blockchain data indicated by the blockchain data request directly in response to the received blockchain data request.
It should be noted that although the blockchain data request is identical in form to the blockchain transaction, it does not necessarily have all properties of the blockchain transaction, for example, after receiving the blockchain data request, the blockchain node does not necessarily recognize the blockchain data request in the blockchain network, but processes the blockchain data request as a local call request, and the blockchain transaction that is not recognized and is only executed inside the local blockchain node is called a local transaction; of course, the blockchain data request may also have all the properties of blockchain transaction, that is, after the consensus transaction is completed in the blockchain network, the consensus transaction is executed by each blockchain node in the blockchain network.
S104: and converting the block chain data into standard data defined by database mode information corresponding to the block chain relational database.
The database schema information related in the embodiments of the present specification specifically refers to a database schema, which is an abstract set of metadata and includes a set of schema components, mainly declaring elements and attributes, and defining complex and simple data types, and specifically includes: defining elements that may appear in a document; defining attributes that may appear in a document; defining which element is a child element; defining an order of the sub-elements; defining a number of sub-elements; defining whether an element is empty or whether it can contain text; defining data types of elements and attributes; default values for elements and attributes are defined, as well as fixed values. Whereas in a database, the schema is the organization and structure of the database. The database schema information includes schema objects, which may be tables (table), columns (column), data types (data type), views (view), stored procedures (stored procedure), relationships (relationships), primary keys (primary keys), foreign keys (foreign keys), and the like. The database schema information can be represented by a visual graph that shows the database objects and their relationship to each other. Since the database schema information is used for describing the structure of the database and can be used as a blueprint for creating a database, how data in the database is stored can be guided by specifying the database schema information corresponding to the database.
After acquiring the block chain data, the node device converts the block chain data into standard data defined by the database schema information based on the database schema information corresponding to the block chain relational database, which means that the converted standard data can be maintained in the block chain relational database according to a certain rule, and the standard data also has a standardized structure and is defined with a relationship with other data in the block chain relational database. The conversion process from the blockchain data to the standard data includes, but is not limited to, conversion of data tables, rows, and columns, for example, conversion from the blockchain data to the standard data is realized through an ETL (Extract-Transform-Load, a data warehouse technology based on data extraction, conversion, and loading) mechanism, and specific implementation manners thereof are described in the prior art, and are not described herein again.
Optionally, in a case that the blockchain data request maintains the blockchain data in the blockchain non-relational database for the intelligent contract, the method further includes:
and initiating a mode information query request to the intelligent contract, and determining first database mode information recorded in the intelligent contract, which is returned by the intelligent contract in response to the mode information query request, as the database mode information corresponding to the block chain relational database.
In this embodiment, the database schema information corresponding to the blockchain relational database may be maintained in advance at the node device (for example, set by an administrator user of the node device), or obtained by requesting from the smart contract. As mentioned above, since each intelligent contract deployed at a block chain node has a corresponding contract storage space in the block chain non-relational database, and each intelligent contract has different characteristics in processing data, organizing data, and storing data, the contract storage spaces corresponding to different intelligent contracts in the block chain non-relational database have different data organization forms, and the data organization forms include formats, relationships, and connotations of data organization, which are also maintained in the intelligent contracts in the form of database mode information. Therefore, in order to correctly deal with blockchain data with different organization characteristics maintained by different intelligent contracts in a blockchain non-relational database, the embodiment of the specification requests the corresponding intelligent contract to acquire the first database mode information maintained in the intelligent contract and corresponding to the blockchain data maintained by the intelligent contract in the non-relational database as the organization mode of the standard data converted by maintaining the blockchain data related to the intelligent contract in the blockchain relational database, so that the standard data related to the intelligent contract is correctly maintained in the blockchain relational database. When a block chain node contains a plurality of intelligent contracts and different intelligent contracts have different data organization forms, the embodiment of the specification can acquire database mode information corresponding to each intelligent contract, and according to the database mode information corresponding to the intelligent contract, the database mode information corresponding to the block chain relational database is used as the database mode information corresponding to the block chain relational database to realize the conversion of block chain data related to the corresponding intelligent contract into standard data, and finally according to the respective database mode information of different intelligent contracts, the standard data related to a plurality of intelligent contracts are correctly maintained in the block chain relational database, at this time, the database corresponding to the block chain relational database is applied with a plurality of different database mode information, and the database mode information corresponding to any intelligent contract only supports the maintenance of the standard data related to any intelligent contract (namely, the standard data obtained by the conversion of the block chain data in any intelligent contract), therefore, a plurality of intelligent contracts adopting different data organization forms are supported, after the blockchain data maintained in the blockchain non-relational database are correctly converted into the standard data, the blockchain data are finally transferred into the blockchain relational database in the form of the standard data for maintenance.
S106: and maintaining the standard data in the blockchain relational database, wherein the blockchain relational database is used for providing data analysis services for analysis demanders.
After obtaining the standard data, the node device may store the standard data in the blockchain relational database according to the blockchain mode information corresponding to the blockchain relational database, so as to implement the conversion and migration from the blockchain data in the blockchain non-relational database to the standard data in the blockchain relational database. Because the blockchain relational database supports various SQL and has strong data analysis capability (such as data query capability based on various conditions, indexes and relations), the blockchain relational database can conveniently provide convenient data analysis service for analysis demanders. For example, a data analysis interface is provided to the outside through a data analysis engine deployed uplink and downlink in the node device, so as to provide a data analysis service for the blockchain relational database to an analysis demander calling the analysis interface to the outside.
In the embodiment of the present specification, the block chain non-relational database and the block chain relational database are respectively deployed on the node device, and on one hand, the block chain non-relational database is used for maintaining block chain data generated when the block chain is operated by the block chain link point, so that the block chain data can be efficiently accessed when the block chain is operated by the block chain link point; on the other hand, the blockchain data maintained in the blockchain non-relational database is converted into standard data and is synchronously maintained in the blockchain relational database, so that convenient data analysis service is realized by using the blockchain relational database. The method for maintaining the block chain data, which is related to the embodiment of the specification, realizes two backup of one data, objectively improves disaster recovery capability, realizes read-write separation of the block chain data through different types of databases, and realizes convenient data analysis service under the condition of ensuring high efficiency of access in the block chain service execution process.
Optionally, the method further includes: receiving a data analysis request sent by the analysis demander; and returning an analysis result obtained by analyzing the block chain relational database based on the data analysis request to the analysis demander. As an embodiment of providing data analysis services, the data analysis engine deployed on the uplink and the downlink of the node device may be further configured to receive a data analysis request sent by an analysis demander, then call a part of data in the block chain relational database for analysis based on the data analysis engine, and finally return an analysis result obtained through analysis to the analysis demander, thereby implementing a complete data analysis service. For example, if the data analysis request is a data query request for simultaneously satisfying the condition a and the condition B, the data analysis engine queries the data having the condition a and the condition B in the blockchain relational database, and returns the data as the analysis result to the analysis demander.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry for implementing the logical method flows can be readily obtained by a mere need to program the method flows with some of the hardware description languages described above and into an integrated circuit.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium that stores computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a server system. Of course, the present invention does not exclude that as future computer technology develops, the computer implementing the functionality of the above described embodiments may be, for example, a personal computer, a laptop computer, a vehicle-mounted human-computer interaction device, a cellular phone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device or a combination of any of these devices.
Although one or more embodiments of the present description provide method operational steps as described in the embodiments or flowcharts, more or fewer operational steps may be included based on conventional or non-inventive approaches. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. When an actual apparatus or end product executes, it may execute sequentially or in parallel (e.g., parallel processors or multi-threaded environments, or even distributed data processing environments) according to the method shown in the embodiment or the figures. The terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, the presence of additional identical or equivalent elements in a process, method, article, or apparatus that comprises the recited elements is not excluded.
