Fig. 2 is a schematic flow chart of a DApp development method applied to a blockchain network according to an embodiment of the present disclosure, where the DApp development method includes the following steps:
s201: and the node equipment receives application attribute information aiming at the target DApp, which is sent by the client, wherein the application attribute information comprises the application function attribute of the target DApp and the identification information of the block chain to be deployed.
The application attribute information may be a requirement document or specification of the target DApp, and in this case, the application function attribute may be an application function that the target DApp indicated by the requirement document or specification needs to have, for example, a voting function, a flow rate statistics function, and the like. The block chain to be deployed can be an independent block chain local area network; or may be a certain blockchain in a plurality of relatively independent blockchain local area networks, in this case, the identification information of the blockchain to be deployed may include two parts: network identification information of the block chain network to be deployed and block chain identification information of the block chain to be deployed. The network identification information may be a character string uniquely identifying the corresponding blockchain network in the blockchain local area network, and the blockchain identification information may be a character string uniquely identifying the corresponding blockchain in the blockchain network corresponding to the network identification information. For example, if the identification information of the block chain to be deployed is 001-. Optionally, when the node device is deployed (or communicated) in a certain blockchain network and the blockchain to be deployed is a blockchain in the blockchain network, in this case, the identification information of the blockchain to be deployed may be blockchain identification information corresponding to the blockchain in the blockchain network, for example, a blockchain number 001. Optionally, when the blockchain network only includes one blockchain, the identification information of the blockchain to be deployed may be network identification information of the blockchain network or blockchain identification information corresponding to the blockchain. Further optionally, the blockchain to be deployed may be any one of a public chain, a private chain, or a federation chain. The client may be a client configured on the application development terminal, or may be a client in communication connection with the application development terminal, which is not limited in this application.
Illustratively, in one application scenario, a user (or DApp developer) sends a demand document for DApp1 (i.e., a target DApp) through a client, which indicates that DApp1 may have traffic statistics functionality and specifies that DApp1 needs to be deployed in a blockchain numbered 001 in a blockchain local area network.
In an embodiment, the application attribute information further carries a private key signature of a user (developer) corresponding to the client, after receiving the application attribute information, the node device obtains a public key corresponding to the private key signature from the blockchain network, performs a dispack on the application attribute information by using the public key, and if the dispack is successful, successfully verifies the identity of the user. In this way, the traceability of DApp during the development process is increased.
Optionally, after receiving registration information submitted by a user through a client, the blockchain network node generates a pair of asymmetrically encrypted keys (a public key and a private key) corresponding to the user after verifying the registration information, so that when the client performs data interaction with the node device, the reliability of data can be improved according to an asymmetric encryption technology (private key signature encryption, public key decryption or decryption) and the data can be prevented from being tampered. And stores the public key broadcast in the blockchain network. The registration information may include information that can uniquely identify the user, such as mailbox information, a mobile phone number, or identity information of the user corresponding to the client.
S202: the node device determines at least one target component from at least one DApp component included in the component library according to the application function attribute.
And the number of DApp components and the number of target components in the component library are one or more, wherein the number of the target components is less than or equal to the number of the DApp components in the component library. The component library is a pre-established DApp component library, and the DApp components contained in the component library may be pre-established by a user (developer) according to functions commonly used in DApp or high in reusability, or may be stored in the component library after being established according to the application attribute information, which is not limited in this embodiment.
In a possible embodiment, the DApp components have function attribute information, and the node device may obtain function attribute information corresponding to each DApp component in at least one DApp component included in the component library, and compare the function attribute information corresponding to each DApp component with an application function attribute of the target DApp. And if the function attribute information is matched (corresponding) with the application function attribute of the target DApp, determining the DApp component corresponding to the function attribute information as the target component. And the function attribute information of the DApp component indicates the specific application function correspondingly realized by the DApp component.
Illustratively, the application function attributes of the target DApp are a traffic monitoring function and an advertisement plug-in function, the component library includes a function that the function attribute information of the DApp component 1 is a random drawing function, the function attribute information of the DApp component 2 is a function of counting the number of drawing times, the function attribute information of the DApp component 3 is a traffic monitoring function, and the function attribute information of the DApp component 4 is an advertisement plug-in function. And the node equipment determines the DApp component 3 corresponding to the matched flow monitoring function and the DApp component 4 corresponding to the advertisement plug-in function as target components by comparing the function attribute information of the DApp components 1, 2, 3 and 4 in the component library with the application function attribute of the target DApp.
In one embodiment, the application function attribute includes at least one (one or more) application function, and before the node device determines the target component from the component library, the node device may generate an intelligent contract corresponding to each of the at least one application function, and further may respectively create a DApp component corresponding to each application function based on the intelligent contract corresponding to each application function, and store the DApp component in the component library.
Illustratively, the application function attributes of DApp2 include two application functions: the node equipment can generate an intelligent contract 1 corresponding to the random drawing function and an intelligent contract 2 corresponding to the statistical drawing function, create a DApp component 1 to bind the intelligent contract 1 to realize the random drawing function, create a DApp component 2 to bind the intelligent contract 2 to realize the statistical drawing function, and store the DApp component 1 and the DApp component 2 in a component library.
Optionally, the plurality of application functions may also correspond to an intelligent contract, integrated in a DApp component. For example, if the application function attribute of the DApp2 includes a random drawing function and a statistical drawing number function, an intelligent contract may be generated according to the random drawing function and the statistical drawing number function, and the DApp component 3 corresponding to the intelligent contract may be created.
Alternatively, a combination of a plurality of components may be stored in a component library as one functional component. For example, if the DApp component 1 corresponds to a random drawing function and the DApp component 2 corresponds to a random drawing number counting function, the DApp component 1 and the DApp component 2 may be combined into a DApp component 3, and the DApp component 3 is used to realize the random drawing number counting function.
S203: and the node equipment obtains a target DApp based on the application attribute information and the at least one target component, and deploys the target DApp in the block chain to be deployed corresponding to the identification information.

In the embodiment of the application, the node device receives application attribute information which is sent by a client and carries a target distributed application, wherein the application attribute information comprises an application function attribute and identification information of a block chain to be deployed. The target distributed application is integrated and developed by calling the component method, so that the reusability of the component function is improved, and the development convenience is improved. And the node equipment deploys the target distributed application in the block chain to be deployed corresponding to the identification information, so that the process from development to deployment of the distributed application is completed, and the development cost such as labor cost, time cost and the like in the development process is saved.

S303: the node device detects whether the functional attribute of the target component is consistent with the application functional attribute.
The node device may compare the application function included in the function attribute of the target component with the application function attribute, and determine whether the function attribute of the target component is consistent with the application function attribute according to a comparison result, that is, check whether all the application functions in the application attribute of the target DApp are implemented, and if it is detected that all the application functions in the application attribute of the target DApp are implemented by the function attribute of the target DApp component, it indicates that the function attribute of the target component is consistent with the application function attribute.

If not, the node device may determine, according to a detection result of whether the functional attribute of the target component is consistent with the application functional attribute, an application function to be added. The application function to be added refers to an application function realized by calling an existing DApp component in the component library due to the fact that the DApp component with the corresponding function attribute information of the application function in the target DApp does not exist in the component library. Illustratively, since the traffic monitoring function DApp component does not currently exist in the component library, and thus the traffic monitoring function of DApp1 cannot be implemented by calling the existing DApp component in the component library, the traffic monitoring function is determined as the application function to be added.
In one embodiment, the application function attribute of the target DApp includes at least one (one or more) application function, the node device compares each application function of the at least one application function with the function attribute information of all target components that have been determined in the previous step, and if the application function does not match with the function attribute information of the target components, the application function that does not match with the function attribute information of the target components is determined as the application function to be added.

Illustratively, the target DApp is an outdoor game competition application, and the target components include a DApp component 1 corresponding to a map function, a DApp component 2 corresponding to a multi-player competition function, a DApp component 3 corresponding to a single-player competition function, and a DApp component 4 corresponding to a score award function. The application function join order of the target DApp is the target component that is formulated by the user (developer) according to the data flow direction between the target components. As shown in fig. 4, the exemplary target components are linked in a linking order, wherein the linking order is that the DApp component 1 is used as a base support for preferential loading, data links with the DApp component 2 and the DApp component 3 respectively, and finally the DApp component 2 and the DApp component 3 are respectively data linked with the DApp component 4 for score reward.
In an embodiment, the application attribute information further includes data attribute information of at least one application function, and further, the node device may add the data attribute information corresponding to the application function to a target component corresponding to each application function according to the data attribute information of each application function, and further, the node device may integrate the target component based on the data attribute information of the target component to obtain the target DApp. The data attribute information includes data sources, data flow directions, statistical rules for generating data, and the like for implementing each application function.
Optionally, the data attribute information further includes data that needs to be stored in the blockchain network and is formulated by a user (developer) according to an actual application scenario of the target DApp, for example, a value of a highest score of the sports game application, advertisement click frequency statistics, and the like.
