Meanwhile, the intermediate code data can be generated according to the operation data, namely, an operation interface used by a new DApp can be generated through a preset interface template and operation on the preset interface template. Wherein the intermediate code data is the basic data of the Dapp interface, and step 203 may be executed to better adapt to the usage of each platform.
Optionally, the intermediate code data of the distributed application program may be stored in a blockchain, so as to prevent loss and tampering, and may be subsequently obtained for use.
In an embodiment, before generating the intermediate code data of the distributed application according to the operation data of the user terminal, the method further includes:
receiving an input item setting request for the operation interface from the user side;
determining the number of the input items of the input item setting request and the data types corresponding to the input items, generating input item setting data, and sending the input item setting data to the user side, wherein the input item setting data comprises the number of the input items and the data types corresponding to the input items.
The user side may set an entry on the DApp page, specifically, an input window on the page, for inputting data during the DApp operation. Different data needs to conform to the corresponding data type. Specifically, the user side may submit an entry content, such as an entry form, including at least one entry (name or identifier) to the backend management side in the form of an entry setting request, and the backend management side may determine, after receiving the entry setting request, the number of entries and the data type corresponding to each entry to generate corresponding entry setting data, and send the entry setting data to the user side.

The data types may include, but are not limited to, integer types and character types. For example, the input item setting request of the user side includes an age and a name, and the background management side can determine, through a preset intelligent contract, that the data types corresponding to the two items are integer and character types, and set the limitation condition of the input item. The user can show the input boxes of age and name, and only the integer data and the character data can be input or only the integer data and the character data can be input and then can be correctly stored or submitted. The method described above can quickly determine and set the entry data type of a DApp page based on intelligent contracts in the blockchain.
Optionally, after receiving the operation request of the user terminal to the operation interface and before generating the operation data, the method further includes:
determining whether the operation request accords with the operation logic of the target interface template;
if yes, an operation permission instruction is sent to the user side, so that the user side executes the operation corresponding to the operation request.
Because the DApp is decentralized, in order to further prevent the user from using the DApp maliciously or by mistake, in this embodiment, an operation logic of a preset interface template may be stored in the background management end or the block chain, so that after receiving the operation request, the background management end may further determine whether the operation request conforms to the operation logic of the target user interface template, if so, the operation permission information is sent to the user end, and after receiving the operation permission information sent by the background management end, the user end executes an operation corresponding to the operation request. The user can operate the DApp according to the operation logic of the target user interface template, the operation behavior of the user on the DApp can be limited, and the stability and controllability of the DApp are improved.

And determining the template platform identification at the user side according to the selection of the user, and generating the conversion instruction. One or more processing modules (or nodes) may be pre-deployed in the blockchain, and are used to support processing of DApp-related data, which may be understood as a conversion service provided by a third party in the blockchain in the embodiment of the present application. The blockchain network identifier may be manually selected by a user side, or may be automatically matched according to a target platform identifier, that is, a module or a node supporting code conversion of the target platform identifier may be randomly selected. After receiving the conversion instruction from the user side, the background management side may obtain the intermediate code data, and execute step 204.

Specifically, a corresponding blockchain processing module may be determined according to the blockchain network identifier, and the intermediate code data and the user key information may be sent to the blockchain processing module for performing a conversion processing operation. The block chain may store a corresponding relationship between a preset platform identifier and an application format frame, so that the block chain processing module may determine the application format frame corresponding to the target platform identifier according to the corresponding relationship. Furthermore, a plurality of identifiers are pre-stored in the block chain processing module, so that the identifiers in the intermediate code data can be identified, fixed parameters in the intermediate code data are extracted, an application program format frame corresponding to the target platform identifier is brought in to form a code to be compiled in a new format, and then a compiling tool is called to compile the code to obtain target application program code data. The target application program code data is the data of the native DApp, that is, the DApp suitable for the target platform can be generated according to the selection of the user.
The public key of each node can be acquired in the block chain, the public key of the user side can be used for signing the acquired target application program code data, and then the signed target application program code data is sent to the user side, so that the safety of data verification is improved. The user terminal can use the private key of the user terminal to verify the signature so as to determine the authenticity of the data source.
In an alternative embodiment, after the step 203, the method further includes:

In one embodiment, some application-related operational data or information may be encrypted and decrypted in a blockchain based on a form of Public Key and private Key (PrivateKey). The public key and the private key are a key pair (i.e. a public key and a private key) obtained through an algorithm, the public key is a public part of the key pair, and the private key is a non-public part. The public key is typically used to encrypt session keys, verify digital signatures, or encrypt data that can be decrypted with a corresponding private key. The key pair derived by such an algorithm is guaranteed to be unique worldwide. When using this key pair, if one of the keys is used to encrypt a piece of data, the other key must be used to decrypt the piece of data. For example, encrypting data with a public key necessitates decryption with the private key, and if encrypting with the private key, also must decrypt with the public key, otherwise decryption will not succeed.
