Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a method and a device for managing a block chain application, computer equipment and a storage medium. Specifically, the embodiment of the present application provides a management apparatus for a blockchain application suitable for a computer device. The computer device may be a terminal or a server, and the terminal may be a mobile phone, a tablet computer, a notebook computer, and the like. The server may be a single server or a server cluster consisting of multiple servers, e.g., a blockchain.

In the embodiment of the present application, a management apparatus of a blockchain application is taken as an example for execution by a server to introduce a management method of a blockchain application.

Referring to fig. 1, the management system for blockchain applications provided in the embodiment of the present application includes a server 10, a terminal 20, and the like; the server 10 and the terminal 20 are connected via a network, such as a wired or wireless network, wherein the management device of the blockchain application is integrated in the server.

The server 10 may obtain a bottom chain type set of the blockchain, where the bottom chain type set includes a bottom chain type of at least one blockchain bottom chain; and determining a target bottom chain type required for creating the block chain from the bottom chain type set. For example, the server 10 may determine the target bottom chain type through the terminal 20, and specifically, the user may determine the target bottom chain type through interaction with the terminal 20, and the terminal 20 may send the target bottom chain type information to the server 10, so that the server 10 may determine the target bottom chain type selected by the user from the bottom chain type set.

The server 10 may create a target blockchain for the target service based on the blockchain bottom chain corresponding to the target bottom chain type. Moreover, the server 10 may deploy a target application of the target service on the target blockchain, and generate an intelligent contract for the target application; and performing data analysis on the on-chain data of the target application block chain through an intelligent contract of the target application so as to manage the target application based on the analysis result.

The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

The method for block chain application provided by the embodiment of the application can be executed by a terminal or a server, or can be executed by the terminal and the server together; in the embodiment of the present application, the management method of the blockchain application is described as an example executed by the server, and as shown in fig. 2, a specific process of the management method of the blockchain application may be as follows:

101. and acquiring a bottom chain type set of the block chains, wherein the bottom chain type set comprises at least one bottom chain type of the block chain bottom chain.

The block chain is a novel application model 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, and as an underlying technology of bitcoin, is a string of data blocks generated by using cryptography correlation, and each data block is linked by a random hash (also called a hash algorithm), and the next block contains the hash value of the previous block. The block chain technology is widely applied to the scenes of digital assets, intelligent contracts, logistics tracking, product protection and the like.

As an example, the blockchain bottom chain may include BCOS (binary, open & Secure) and Fabric, where BCOS (Be credit named) is a blockchain technology Open source platform focused on enterprise-level application services and has been fully verified in a plurality of enterprise-level application scenarios; fabric is a licensed blockchain framework. It provides a modular framework to serve nodes in the framework, execution of intelligent contracts, and configurable consensus and membership.

The bottom chain type is a type of a bottom chain of the blockchain, for example, the bottom chain type may include a BCOS type and a Fabric type, and the like.

In an embodiment, a server may determine a bottom chain of a blockchain capable of supporting creation, and further determine a bottom chain type set of the blockchain, where the bottom chain type set includes a bottom chain type of at least one bottom chain of the blockchain, and the server may create the blockchain based on the bottom chain of the blockchain corresponding to each bottom chain type.

In another embodiment, the terminal may design a blockchain hub management and control platform corresponding to the management method for blockchain applications, and the server may send information of a bottom chain type set to the terminal after acquiring the bottom chain type set of the blockchain, so that the terminal may display a corresponding bottom chain type in the blockchain hub management and control platform. As an example, fig. 3 illustrates a blockchain backbone management platform of a terminal design, wherein the blockchain backbone management platform provides functions of blockchain management and supports a bottom chain type set for displaying blockchains in related pages. For example, the terminal may present a bottom-chain type list in response to a selection operation directed to the bottom-chain type control shown in 1001, where the bottom-chain type list includes each bottom-chain type in the bottom-chain type set.

102. And determining a target bottom chain type required for creating the block chain from the bottom chain type set.

For example, the server may determine the target bottom chain type through the terminal, for example, a user may select the target bottom chain type from the bottom chain type set through a block chain hub management and control platform of the terminal, and further, the terminal may send information of the target bottom chain type to the server, so that the server may determine the target bottom chain type required for creating the block chain from the bottom chain type set.

As an example, referring to fig. 3, the terminal may obtain, through the control 1001, a target bottom chain type determined by the user from the bottom chain type set, and further, the terminal may send target bottom chain type information to the server, so that the server may determine, from the bottom chain type set, the target bottom chain type required for creating the block chain.

In practical application, the target bottom chain required for creating the block chain can be determined after the target bottom chain type is determined, and the target bottom chain can be determined by determining the bottom chain type and the bottom chain version because the same bottom chain type can include the block chain bottom chains with different bottom chain versions. As an example, referring to fig. 3, the terminal may obtain, through a control 1001, a bottom chain type determined by a user from a bottom chain type set, and obtain, through a control 1002, a bottom chain version of the bottom chain type determined by the user, and the terminal may send bottom chain type information and bottom chain version information to the server, so that the server may determine, based on the bottom chain type information and the bottom chain version information, a target bottom chain required to create a block chain from the bottom chain type set.

103. And creating a target block chain of the target service based on the block chain bottom chain corresponding to the target bottom chain type.

Related applications of the service can be deployed on the blockchain, so that the service can be provided with services by using the blockchain. In this application, the application related to the target service may be deployed on the target block chain, for example, the target service may be a data sharing service, and the target bottom chain type may be a BCOS type, so that the target block chain may be created based on the BCOS of the block chain bottom chain corresponding to the BCOS type, and the data sharing application of the data sharing service may be deployed on the target block chain, so that the data sharing service may provide the data sharing service by using the target block chain.

It should be noted that, in the present application, for different target bottom chain types determined in step 102, the server may create different target blockchains based on the blockchain bottom chains corresponding to the different target bottom chain types, so that, in the present application, the server can support the creation of blockchains belonging to different types of bottom chains.

Correspondingly, as a specific application of the present application, the blockchain backbone management and control platform on the terminal may provide the following functions to the user: and generating the block chains of the different types of bottom chains on the same block chain central control platform.

In one embodiment, the present application may be applied to a federation chain, where the federation chain is a block chain for between enterprises, the federation chain being only for members of a particular group and limited third parties, and having designated therein a plurality of preselected nodes as billers, the generation of each block being determined jointly by all of the preselected nodes. Therefore, the server may create a blockchain applicable to the inter-enterprise service based on the blockchain bottom chain corresponding to the target bottom chain type, and specifically, the step "create a target blockchain of the target service based on the blockchain bottom chain corresponding to the target bottom chain type" may include:

determining attribute information of a target block chain to be created;

based on the block chain bottom chain and the attribute information, an initial block chain of the target service is created;

and adding a member mechanism for the initial block chain to obtain an added target block chain, wherein the member mechanism has data processing authority aiming at the target block chain.

The attribute information of the target blockchain is information describing an attribute of the target blockchain, and for example, the attribute information may include a name of the blockchain, an encryption algorithm supported by the blockchain, an organization to which the blockchain belongs, a host node of the blockchain, a number of nodes of the blockchain, and the like.

Specifically, when the method is applied to a scenario of a federation chain, a finally generated target blockchain is composed of different blockchain link points, and each blockchain node belongs to different member authorities, so that in the scenario of the federation chain, member authorities also need to be added to the initial blockchain to create a target blockchain applied to participation of the federation chain.

Wherein the member enterprises are members of enterprises participating in the federation chain, each member enterprise can contribute blockchain nodes to the finally generated blockchain, and the member enterprises have data processing authority for the finally generated blockchain.

The data processing permission is a processing permission for data on a link of the target block chain, for example, the data processing permission may include a data writing permission, a data reading permission, a data deleting permission, a data modifying permission, and the like.

In an embodiment, referring to fig. 4, the server may create a target blockchain of the target service based on the blockchain bottom chain corresponding to the target bottom chain type to obtain the service sub-chain of the target service. Specifically, the server may determine the type of the service sub chain to be created by determining the bottom chain type, and determine the bottom chain version under the service sub chain type by determining the bottom chain version, so that the block chain bottom chain required for creating the service sub chain may be determined by the bottom chain type and the bottom chain version. In addition, the server may also determine attribute information of the service sub-chain to be created by determining a sub-chain name, a chain encryption type, an affiliated organization, a host node, an initial node number, and the like of the service sub-chain.

Further, the server may create an initial blockchain based on the blockchain bottom chain and the attribute information. For example, the server may adjust the attribute of the blockchain bottom chain based on the attribute information of the service sub-chain on the basis of the blockchain bottom chain, and use the adjusted blockchain bottom chain as the initial blockchain.

In an application scenario of a federation chain, referring to fig. 4, a server may obtain an added target blockchain by adding a member enterprise to an initial blockchain. Specifically, if it is determined that other organizations need to be invited, the server may send an invitation to the organization to join the service sub-chain through an Identity (ID) of the organization to be invited. It should be noted that other entities are required to join the service subchain, and when creating the chain, the invited entity must agree first and then create the chain by the operation and maintenance manager.

In addition, referring to fig. 4, if it is not necessary to add a member mechanism to the initial blockchain, the initial blockchain may be used as a target blockchain to obtain a target blockchain of the target service.

In practical applications, the server may give a preset account a right to create a target block chain, for example, in an application scenario of a federation chain, an account for creating the target block chain needs to be checked to determine whether the account meets a criterion of the federation chain. Specifically, the step "creating a target block chain of the target service based on the block chain bottom chain corresponding to the target bottom chain type" may include:

determining a target account number for creating a target block chain;

performing authority verification on the target account to determine the block chain creation authority of the target account;

and when the permission check is detected to pass, establishing a target block chain of the target service through the target account based on the block chain bottom chain.

For example, in an embodiment, referring to fig. 5, a user may apply for an account of a developer through a block chain hub control platform provided by a terminal, the server may obtain application information through the terminal and check through an operation and maintenance platform, and if the application information passes the check, the server may return the check-passing information to the terminal, so that the user may receive the check-passing information through the terminal and perform account login at the terminal. When a user logs in a developer account at a terminal, the terminal can send login information to a server, and the server can determine the account as a target account for creating a target block chain.

Further, the server also needs to perform permission check on the target account to determine whether the target account has a block chain creation permission, and when it is detected that the permission check of the target account passes, the target account is allowed to create a target block chain of the target service based on the bottom chain of the block chain. For example, when detecting that the authority of the target account passes verification, the server may send verification passing information to the terminal, so that a user corresponding to the target account may execute a relevant operation of creating a target block chain through a block chain hub management and control platform of the terminal.

Specifically, the step "performing an authority check on the target account to determine the blockchain creation authority of the target account" may include:

performing attribution verification on the target account to verify attribution mechanism information of the target account to obtain a first verification result;

performing node verification on the target account to verify the node information of the target account to obtain a second verification result;

and determining the block chain creation authority of the target account number based on the first check result and the second check result.

For example, in an application scenario of a federation chain, the attribution check may be performed on the target account to determine whether the institution to which the target account belongs is a member institution of the federation chain.

In one embodiment, referring to fig. 5, when the user's developer account audit passes, the user may add an organization through the developer account to join the federation chain. Specifically, the method may include the steps of adding an organization name, adding an organization identifier, and creating the affiliated organization. After the developer account successfully creates the organization, if the server performs attribution verification on the developer account, it can be determined that the attribution verification of the developer account passes.

The node check is used to check node information of the target account, for example, the node information may include IP information, a mechanism to which the node belongs, a data transmission account, a port, and the like.

In an embodiment, referring to fig. 5, when the developer account of the user passes the audit, the user may add host node information through the developer account, specifically, the method may include adding a host IP Address (Internet Protocol Address refers to an Internet Protocol Address, and is also translated into an Internet Protocol Address), selecting a mechanism to which the user belongs, and filling in an SSH (secure shell, chinese is a secure shell Protocol) account and an SSH port. After the host is successfully added to the developer account, if the server performs node verification on the developer account, it can be determined that the node verification of the developer account passes.

It is noted that in practical applications, it is checked before adding a host whether the performance requirements are met, otherwise the addition may fail.

The method for determining the block chain creation permission based on the first check result and the second check result may be various, for example, it may be set that when both the first check result and the second check result pass the check, the target account is determined to have the block chain creation permission; for another example, it may be set that if the first check result or the second check result is that the check is passed, it is determined that the target account has the creation permission of the block chain; for another example, different weights may be set for the first check result and the second check result, so that whether the target account has the creation permission of the blockchain may be determined through weighted calculation; and so on.

104. Deploying a target application of a target service on a target blockchain, and generating an intelligent contract for the target application.

An intelligent contract is a computer protocol that aims to propagate, verify or execute contracts in an informational manner. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible.

On the created target block chain, a corresponding service application may be developed, where the data uplink mechanism and the processing interface may implement automated processing through an intelligent contract, and therefore, the server may deploy the target application of the target service on the target block chain and generate an intelligent contract for the target application, specifically, the step "deploy the target application of the target service on the target block chain" may include:

acquiring an application to be deployed of a target service, wherein the application to be deployed has corresponding application attribute information;

determining a member institution of the application to be deployed, wherein the member institution has a data processing authority for the application after deployment;

and deploying the application to be deployed to the target block chain based on the application attribute information and the member mechanism so as to deploy the target application of the target service on the target block chain.

The application attribute information is information describing an attribute of the target application, and for example, the application attribute information may include an application name, an application version number, and the like.

In an embodiment, a server may obtain an application to be deployed of a target service, where the application to be deployed has corresponding application attribute information, and specifically may include an application name, an application version number, and the like.

In another embodiment, referring to fig. 6, a user may add an application to be deployed newly through a blockchain hub management and control platform of a terminal, and determine a target blockchain for deploying the application to be deployed, an application name of the application to be deployed, an application version number, and the like. Accordingly, the server can obtain the application to be deployed of the target service through the terminal and determine the application attribute information of the application to be deployed.

Further, the server may determine a member authority to deploy the application, wherein the member authority has data processing rights for the deployed application. It is noted that different member organizations may be provided with different levels of data processing permissions for the post-deployment application.

After determining the application attribute and the member mechanism of the application to be deployed, the server deploys the application to be deployed to the target block chain based on the application attribute information and the member mechanism, so as to deploy the target application of the target service on the target block chain.

In addition, the server may also generate an intelligent contract of the target application, and specifically, the step "generating an intelligent contract of the target application" may include:

acquiring program information of an intelligent contract;

compiling the program information to obtain a compiled intelligent contract;

and establishing a connection relation between the compiled intelligent contract and the target application to obtain the intelligent contract of the target application.

The intelligent contract is a computerized agreement, can execute the terms of a certain contract, and particularly can be realized by codes which are deployed on a shared account and are used for executing when certain conditions are met, and is used for completing automated transaction according to actual business requirement codes, such as inquiring the logistics state of goods purchased by a buyer and transferring the electronic money of the buyer to the address of a merchant after the buyer signs the goods; of course, intelligent contracts are not limited to executing contracts for trading, but may also execute contracts that process received information.

As an example, the program information of an intelligent contract may be code information that may be used to execute the intelligent contract when certain conditions are met.

In an embodiment, the server may obtain the program information of the intelligent contract through the terminal, for example, referring to fig. 7, the user may input the program information of the intelligent contract through the code editing area described in fig. 7 on the blockchain hub management and control platform of the terminal, so that the server may obtain the program information through the terminal.

In an embodiment, the program information of the intelligent contract acquired by the server may be code information written in a solid language, and the server may compile the program information to obtain a compiled intelligent contract. In addition, the server may further send information related to the compiled smart contract to the terminal, so that the terminal may display the information related to the compiled contract through the blockchain hub management and control platform, for example, referring to fig. 7, an Application Binary Interface (ABI) after the contract is compiled, bin information, a version number of the contract, a contract name, and the like may be displayed in the contract information display area.

The connection relation between the compiled intelligent contract and the target application is used for setting the compiled intelligent contract as the intelligent contract used by the target application.

For example, referring to fig. 6, after acquiring a contract name, a contract path, and program information of the intelligent contract through the terminal, the server may compile the intelligent contract to obtain a compiled intelligent contract, and the server may execute contract deployment on the compiled intelligent contract to deploy the intelligent contract on the target block chain and set the intelligent contract for the target application, thereby establishing a connection relationship between the compiled intelligent contract and the target application.

In practical applications, in addition to generating an intelligent contract of a target application and performing contract deployment on the intelligent contract, similarly, the intelligent contracts of other applications on the same blockchain and the intelligent contracts of other applications on different blockchains may also be generated and further managed, and specifically, in the step "generating an intelligent contract of a target application", the method may further include:

specifically, the step "generating an intelligent contract for a target application" may further include:

acquiring attribute information of at least one intelligent contract;

analyzing the attribute information to obtain attribution information and state information of the intelligent contract, wherein the attribution information represents the application of the intelligent contract, and the state information represents the contract state of the intelligent contract;

and managing the intelligent contract based on the attribution information and the state information.

The attribute information of the intelligent contract is information describing the attribute of the intelligent contract, and the attribute information of the intelligent contract may include a contract name, a contract address, an affiliated application, an affiliated block chain, a contract language, a contract state, creation time, and the like of the intelligent contract.

The server may obtain attribute information of at least one intelligent contract, where the intelligent contracts may be intelligent contracts belonging to the same application, or intelligent contracts belonging to different applications, for example, may be intelligent contracts belonging to different applications on the same blockchain, or may be intelligent contracts belonging to different applications on different blockchains.

Wherein the attribution information of the intelligent contract represents the application to which the intelligent contract belongs; the state information of the intelligent contract characterizes the contract state of the intelligent contract, for example, the contract state may include: deployed, undeployed, decommissioned, and so forth.

In an embodiment, after the server generates an intelligent contract of a target application and executes contract deployment on the intelligent contract, the server may further obtain attribute information of the intelligent contract, where the attribute information may specifically include a contract address, an application to which the contract belongs, a business sub-chain to which the contract belongs, a contract state, contract creation time, and the like, and further manage the intelligent contract.

The server may manage the intelligent contracts in various ways, for example, the intelligent contracts may be classified according to the attribution information and the status information; for another example, referring to fig. 8, the server may send attribute information of each intelligent contract to the terminal to trigger the terminal to display an intelligent contract information list, where the intelligent contract information list includes at least one intelligent contract information item, and each intelligent contract information item corresponds to attribute information of one intelligent contract.

105. And performing data analysis on the on-chain data of the target application block chain through an intelligent contract of the target application so as to manage the target application based on the analysis result.

Wherein the on-chain data is data stored on the target block chain by the target application. Due to the specific chain type storage structure of the block chain, data on the chain can only be acquired and called in an intelligent contract interface mode, therefore, in the application, data analysis can be performed on the data on the chain of the target application block chain through an intelligent contract of the target application, and the target application is managed based on an analysis result. Specifically, the step "performing data analysis on the on-chain data of the target application in the target blockchain through the intelligent contract of the target application to manage the target application based on the analysis result" may include:

determining a target intelligent contract required for data analysis of a target application;

acquiring the link data of the target application in the target block chain by calling an interface of the target intelligent contract;

and performing data analysis on the data on the chain so as to manage the target application based on the analysis result.

Due to the technical characteristics of the scarce computing capability of the node of the block chain, the data structure of key value storage and the like, the complex data query, data analysis, data computation and the like which are not suitable for the block chain are determined, and the work is more suitable for being completed under the chain. Thus, in this embodiment, the server may determine a target intelligent contract for retrieving on-chain data for a target application for a target blockchain.

The server may obtain the data on the link of the target application in the target block chain by calling the interface provided by the target intelligent contract, and specifically, in order to improve efficiency, referring to fig. 9, the server may obtain the logic records of different blocks in a multi-thread manner by task scheduling, so as to efficiently obtain the data on the link of the target application in the target block chain.

Further, the server may analyze the acquired on-chain data to manage the target application based on the analysis result. Specifically, the step "performing data analysis on the data on the chain" may include:

carrying out structured analysis on the data on the chain to obtain structured data of the data on the chain;

generating a data processing interface for the structured data;

and performing data analysis on the structured data based on the call request aiming at the data processing interface.

The structured parsing is used for generating structured data, specifically, the structured data is also called row data, is logically expressed and implemented by a two-dimensional table structure, strictly follows the data format and length specification, and is mainly stored and managed by a relational database.

The Interface is also called Application Programming Interface (API), and is some predefined interfaces (such as functions) or conventions for linking different components of a software system. The interface may be used to provide applications and a set of routines that developers have access to based on certain software or hardware without having to access source code or understand the details of the internal working mechanisms.

In this embodiment, the data processing interface for structured data is an interface providing different data processing functions for structured data, for example, referring to fig. 9, the data processing interface may include a CRUD interface for structured data, where CRUD refers to acronyms of several words of add (Create), retrieve (Retrieve), update (Update), and Delete (Delete) when doing computing processing. CRUD is used primarily to describe the basic operational functions of a database or persistence layer in a software system.

For example, referring to fig. 9, after structured data of the data on the chain is obtained by performing structured parsing on the data on the chain, the server may further perform structured storage on the structured data obtained by parsing through the relational database, and provide a data processing interface in the relational database, for example, a CRUD interface, to generate a mutual data processing interface for the structured data.

Further, the server may obtain a call request of the upper layer user for the data processing interface, and perform corresponding data processing on the structured data, so as to analyze the structured data. For example, operations of adding, deleting, modifying and checking structured data can be performed, visual display of data can be achieved, data analysis can be performed, and the like.

In addition, after the data on the chain is acquired, the server can also perform standardized processing on the chain data according to a chain storage mode, and can assist and automatically store the program data into the database through a persistence framework. Specifically, after the step "acquiring the on-chain data of the target application in the target block chain", the method may further include:

standardizing the data on the link based on a storage mode of the data on the link in the target block chain to obtain standardized data of the data on the link;

the normalized data is stored to a down-link database of the target blockchain.

The storage mode of the data on the block chain may be various, for example, the storage mode may include a chain storage mode, specifically, the chain storage mode stores data elements in a computer memory in a storage unit with an arbitrary address, and the logical relationship between the data elements is implemented in a pointer connection mode.

Wherein the normalization of the data is to scale the data to fall within a small specified interval. In some index processing for comparison and evaluation, unit limitation of data is removed and converted into a dimensionless pure numerical value, so that indexes of different units or orders can be compared and weighted conveniently. The most typical method is data normalization, i.e. mapping data onto [0,1] interval uniformly, and the common methods for data normalization include: dispersion normalization (Min-max normalization), log function transformation, atan function transformation, standard deviation normalization (zero-mean normalization, z-score normalization), fuzzy quantization, and the like.

In this embodiment, the server may perform normalization processing on the on-chain data based on a chain storage mode of the on-chain data in the target block chain to obtain normalized data of the on-chain data, so that data analysis may be performed on the on-chain data based on the normalized data in the subsequent step.

After obtaining the normalized data of the on-chain data, the normalized data may also be stored to the off-chain database of the target blockchain, e.g., the normalized data may be stored to the off-chain database of the target blockchain as needed based on the data derivation model of the on-chain data. Specifically, the step "storing the normalized data in the under-link database of the target block chain" may include:

determining a data derivation model for the data on the chain;

extracting target data information corresponding to the data derivation model from the standardized data;

combining the target data information based on the data export model to obtain combined information;

and storing the combined information into a down-link database of the target block chain.

Where the data export model is a specification to which the on-chain data is exported from the target database, for example, the data export model may include: a block chain detailed data export model, a block transaction data export model, a contract information export model and the like.

Specifically, the blockchain detailed data derivation model may be configured to derive detailed data of each block, which may specifically include a block hash, a block height, a block derivation time, a transaction amount on a block, and the like; the block transaction data derivation model can be used for deriving basic information of each transaction in each block, and specifically can include block hashes, block heights, block out times, intelligent contract names, contract method names, transaction hashes, transaction initiator addresses, transaction receiver addresses and the like; the block contract information derivation model may be configured to derive relevant information of a contract, and specifically may include an Application Binary Interface (ABI) after the contract is compiled, bin information, a version number of the contract, a contract name, and the like.

After determining the data derivation model of the data on the chain, the target data information corresponding to the data derivation model may be extracted from the normalized data, for example, in an embodiment, the data derivation model of the data on the chain is a block chain detailed data derivation model, and the server may extract the target data information including block hash, block height, block time, transaction amount on the block, and the like from the normalized data of the data on the chain. For another example, in an embodiment, the data export model of the data on the link is a block transaction data export model, and the server may extract target data information including a block hash, a block height, a block out time, an intelligent contract name, a method name in a contract, a transaction hash, a transaction initiator address, a transaction receiver address, and the like from the standardized data of the data on the link; and so on.

Further, the extracted target data information may be combined based on a data derivation model of the data on the link to obtain combined information.

As an example, in an embodiment, the data derivation model for the data on the chain is a blockchain detailed data derivation model, wherein the model specification of the blockchain detailed data derivation model may be as follows:

the server may extract target data information corresponding to the model from the standardized data extraction blockchain detailed data, where the extracted target data information may specifically include a key ID, a block hash, a block height, a block exit time, a current block transaction amount, a record insertion/update time, and a block time. Further, the server may combine the extracted target data information based on a model specification of the block chain detailed data derivation model to obtain combined information.

As an example, in another embodiment, the data derivation model for the on-chain data is a block transaction data derivation model, wherein the model specification for the block transaction data derivation model may be as follows:

the server may extract target data information corresponding to the block transaction data derivation model from the standardized data, where the extracted target data information may specifically include a key ID, a block hash, a block height, a block exit time, a contract name of the transaction, a function name called by the transaction, a transaction hash, a transaction initiator address, a transaction receiver address, and a record insertion/update time. Further, the server may combine the extracted target data information based on a model specification of the block transaction data derivation model to obtain combined information.

As an example, in another embodiment, the data-derived model of the on-chain data is a contract information-derived model, wherein the model specification of the contract information-derived model may be as follows:

the server may extract target data information corresponding to the contract information derivation model from the standardized data, where the extracted target data information may specifically include a primary key ID, an ABI hash value, a contract ABI, contract Bin information, a contract name, a version number, and record insertion/update time. Further, the server may combine the extracted target data information based on a model specification of the contract information derivation model to obtain combined information.

After the combined information is obtained, the combined data may be stored in a downlink database of the target block chain, where the downlink database is a database that can provide storage in addition to the target block chain, and for example, the downlink database may include a relational database and a non-relational database, etc.

In practical applications, form data corresponding to each data derivation model may also be derived from the down-link database based on the data derivation model, so that data analysis and management can be performed on the blockchain application based on the derived data.

As can be seen from the above, in this embodiment, a bottom chain type set of a blockchain may be obtained, where the bottom chain type set includes a bottom chain type of at least one blockchain bottom chain; determining a target bottom chain type required for creating a block chain from the bottom chain type set; creating a target block chain of the target service based on the block chain bottom chain corresponding to the target bottom chain type; deploying a target application of the target service on the target blockchain, and generating an intelligent contract of the target application; and performing data analysis on the link data of the target application in the target block chain through the intelligent contract of the target application so as to manage the target application based on the analysis result.

The scheme can provide a bottom chain type set comprising at least one bottom chain type, and based on the block chain bottom chain of each bottom chain type, the block chains of different bottom chains are created, so that the applications are deployed on the created block chains, and the data analysis and the application management are carried out on the deployed applications through intelligent contracts. That is to say, the present application not only can support the creation of the blockchains belonging to different bottom chains, but also can support the deployment of applications on different blockchains and perform data analysis and management on the deployed applications, and therefore, the present application can manage multi-chain multi-applications, and compared with a management method of only supporting the blockchain application of a single bottom chain, the present application can effectively improve the management efficiency of the blockchain application, and can avoid invariance and inefficiency brought by only supporting the management of the applications on the single bottom chain.

Secondly, the scheme supports mainstream alliance chains such as FISCO BCOS and Hyperridge Fabric, provides multiple choices for users, and can provide standards to access to the bottom-layer platforms of other manufacturers. The scheme provides development tools such as contract Integrated Development Environment (IDE) and the like, and realizes one-stop development kits such as online editing, compiling, debugging and deploying of contracts. And the complex block chain technology can be packaged into a simple and easy-to-use API, so that the system can be applied to any language development, and the convenience of system chain modification is improved. In addition, a general block chain application component is built in the scheme, an intelligent contract which is verified for a long time is built in the scheme, a service layer does not need to be developed, and the intelligent contract can be used after being opened.

In addition, the scheme may deploy a blockchain backbone management and control platform for the user, and support a developer platform and a data operation and maintenance and analysis platform, as shown in fig. 10. And basic components provided by the hub, such as private key escrow, message queues, CA (certificate authority) certificate services, contract security detection services. The operation and maintenance management module supports services such as application management, statistical log management, contract management and node management.

In addition, the scheme also provides a powerful data analysis and management module aiming at the block chain application, can analyze the transaction, export the transaction to an out-of-chain storage system, realize the structured processing of the data, and access a data analysis and visualization system. The method can provide a data supervision platform for a supervision mechanism, and can conveniently search and monitor illegal contents on the chain.

The method described in the above examples is further described in detail below by way of example.

In this embodiment, a management device for a blockchain application is integrated in a server and a terminal, and the server may be a single server or a server cluster composed of a plurality of servers; the terminal can be a mobile phone, a tablet computer, a notebook computer and other equipment.

As shown in fig. 11, a method for managing blockchain applications includes the following specific processes:

201. the server acquires a bottom chain type set of the block chains, wherein the bottom chain type set comprises at least one bottom chain type of the block chain bottom chain.

In an embodiment, a server may determine a bottom block chain capable of supporting creation of a block chain, and further determine a bottom chain type set of the block chain, where the bottom chain type set includes a bottom chain type of at least one bottom block chain, and the server may create the block chain based on the bottom block chain corresponding to each bottom chain type.

In addition, as a specific application of the present application, the terminal may be configured with a blockchain center management and control platform as shown in fig. 12, wherein for the management method of blockchain applications described in the present application, the blockchain center management and control platform may be correspondingly provided with functions of data overview, organization management, host management, blockchain management, application management, contract management, private key management, certificate management, notification center, and user management.

Referring to fig. 12, as the data overview function provided by the blockchain backbone management platform is shown, the user can learn the overview of the blockchains and the applications through the data overview page, such as the number of blockchains, the number of applications, the number of organizations, the number of hosts, and so on. Further, the data overview page may also be provided with operation guidelines as shown in fig. 12.

Wherein, the organization management can be used for the user to add new organizations and to learn the relevant information of all organizations. For example, an organization information list may be presented on an organization management page, where the organization information list includes at least one organization information item, and each organization information item corresponds to attribute information of an organization, such as an organization number, an organization name, an organization creation time, and the like.

The host management is also called node management, and the node management can provide functions of pre-lists, node lists and node consensus state modification. The user can add the new node to the prepositive list by adding the new node prepositive. The system will default to pull the group where the prefix is located and the node information of each group. In the node list, the user may modify the consensus status of the nodes.

The block chain management is used for the user to add a block chain and to obtain the relevant information of all the created block chains. For example, the blockchain information list may be presented in the blockchain management page, where the blockchain information list includes at least one blockchain information item, and each blockchain information item corresponds to attribute information of one blockchain, such as a blockchain ID, a blockchain name, a blockchain type, a blockchain status, a blockchain creation time, and the like.

The application management can be used for a user to add new applications and learn relevant information of all the applications. For example, an application information list may be presented in the application management page, where the application information list includes at least one application information item, and each application information item corresponds to attribute information of one application, such as an application ID, an application name, an application version, a block chain to which the application belongs, an application state, an application creation time, and the like.

Among other things, contract management may provide a CRUD functionality for a contract development IDE environment, a list of deployed contracts, contract queries, and precompiled contracts.

Similarly, private key management, certificate management, and user management, may provide management functions for private keys, certificates, and users in the blockchain, respectively. As an example, private key management may be used for newly creating a private key user and a public key user, and specifically, private key management may be used for newly creating a private key user, where the private key is to be hosted in a signature service, and then signing contract deployment and contract invocation through the signature service. It is noted that the external account can be imported through the newly created public key account, and is mainly used for associating the transaction with the user.

202. And the server sends the bottom chain type set to the terminal, and the terminal determines a target bottom chain type required by block chain creation from the bottom chain type set.

In an embodiment, the server may determine the target bottom chain type through the terminal, for example, the user may select the target bottom chain type from the bottom chain type set through a blockchain hub management and control platform of the terminal, and further, the terminal may send the target bottom chain type information to the server, so that the server may determine the target bottom chain type required for creating the blockchain from the bottom chain type set.

203. And the terminal sends the target bottom chain type to the server.

204. And the server creates a target block chain of the target service based on the block chain bottom chain corresponding to the target bottom chain type.

In an embodiment, the present application may be applied to a federation chain, where a server may determine attribute information of a target blockchain to be created, further create an initial blockchain of a target service based on a blockchain bottom chain and the attribute information, and add a member authority to the initial blockchain to obtain an added target blockchain, where the member authority has a data processing right for the target blockchain. If no member mechanism needs to be added to the initial block chain, the initial block chain can be used as a target block chain to obtain a target block chain of the target service.

In another embodiment, the server may give a preset account the right to create the target blockchain, for example, in an application scenario of the federation chain, an account for creating the target blockchain needs to be checked to determine whether the account meets a criterion of the federation chain. Therefore, the server may determine a target account for creating a target block chain, and perform an authority check on the target account to determine a block chain creation authority of the target account. And when the permission check is detected to pass, establishing a target block chain of the target service through the target account based on the block chain bottom chain.

In this embodiment, the blockchain hub management and control platform on the terminal may set a developer management page accordingly, and referring to fig. 13, the developer management may be used for the operation and maintenance manager to add new developers and learn about information of all developers. For example, a developer information list may be presented in a developer management page, where the developer information list includes at least one developer information item, and each developer information item corresponds to attribute information of a developer, such as a developer name, a belonging business, a mailbox, a telephone, a status, an account creation time, and the like.

205. The server deploys a target application of the target service on the target blockchain and generates an intelligent contract of the target application.

In an embodiment, a server may obtain an application to be deployed of a target service, where the application to be deployed has corresponding application attribute information. Further, the server may determine a member organization of the application to be deployed, where the member organization has a data processing permission for the application after deployment, and in this case, the server may deploy the application to be deployed to the target block chain based on the application attribute information and the member organization, so as to deploy the target application of the target service on the target block chain.

In an embodiment, the server may obtain program information of the intelligent contract, and perform compiling processing on the program information to obtain a compiled intelligent contract, and further, the server may establish a connection relationship between the compiled intelligent contract and the target application to generate the intelligent contract of the target application.

206. And the server performs data analysis on the link data of the target application in the target block chain through the intelligent contract of the target application so as to manage the target application based on the analysis result.

In an embodiment, the server may determine a target intelligent contract required for data analysis on the target application, and obtain the on-chain data of the target application in the target block chain by calling an interface of the target intelligent contract, and further, the server may perform data analysis on the on-chain data to manage the target application based on an analysis result.

As can be seen from the above, the embodiment of the present application may provide a bottom chain type set including at least one bottom chain type, create block chains belonging to different bottom chains based on the bottom chain of the block chain of each bottom chain type, further deploy an application on the created block chain, and perform data analysis and application management on the deployed application through an intelligent contract. That is to say, the embodiment of the present application may support not only creation of block chains belonging to different bottom chains, but also deployment of applications on different block chains and data analysis and management of the deployed applications, so that the embodiment of the present application may manage multi-chain and multi-application, and compared with a management manner that only supports a single bottom chain block chain application, the embodiment of the present application may effectively improve management efficiency of block chain applications, and may avoid invariance and inefficiency caused by only supporting management of applications on a single bottom chain.

Moreover, the method and the device can quickly construct a block chain technology platform, have visual deployment nodes, quickly construct the chain and centrally manage multiple chains. The method provides convenient operation and maintenance management tools for contract management, node management, certificate management, private key management, configuration management and the like. And multiple block chain applications can be managed on the same management platform, so that centralized management of multiple chains and multiple applications is realized.

In order to better implement the method, correspondingly, the embodiment of the present application further provides a management device for the blockchain application, wherein the management device for the blockchain application may be integrated in a server or a terminal. The server can be a single server or a server cluster consisting of a plurality of servers; the terminal can be a mobile phone, a tablet computer, a notebook computer and other equipment.
