Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
Referring to the data processing system shown in fig. 1A, the data processing system may include a blockchain network 100, and a user terminal 102. Wherein:
the blockchain network 100 refers to a network for performing data sharing between nodes. The blockchain network may include a plurality of nodes 101, and the plurality of nodes 101 may refer to respective clients in the blockchain network. Each node 101 may receive input information and maintain shared data within the blockchain network based on the received input information while operating normally. In order to ensure information intercommunication in the blockchain network, information connection can exist between each node in the blockchain network, and information transmission can be carried out between the nodes through the information connection. For example, when any node in the blockchain network receives input information, other nodes in the blockchain network acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes in the blockchain network are consistent.
The user terminal 102 may access the blockchain network and communicate with nodes in the blockchain network, such as to send transaction data in a target format to the nodes in the blockchain network. Among them, the user terminal 102 runs a Decentralized Application (DApp). Decentralized applications may also be referred to as distributed applications. For example, the decentralized application may be a game application or a mining application, and embodiments of the present invention are not limited thereto. The user terminal 102 includes, but is not limited to, a smart phone, a tablet computer, a desktop computer, and the like.
It should be noted that the number of nodes shown in fig. 1A is merely illustrative, and any number of nodes may be deployed according to actual needs.
Each node in the blockchain network has a corresponding node identifier, and each node in the blockchain network can store node identifiers of other nodes in the blockchain network, so that the generated block can be broadcast to other nodes in the blockchain network according to the node identifiers of other nodes. Each node may maintain a node identifier list as shown in the following table, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an IP (Internet Protocol) address and any other information that can be used to identify the node, and table 1 only illustrates the IP address as an example.
Each node in the blockchain network stores one identical blockchain. The block chain is composed of a plurality of blocks, referring to fig. 1B, the block chain is composed of a plurality of blocks, the starting block includes a block header and a block main body, the block header stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.
When each block in the block chain is generated, referring to fig. 1C, when the node where the block chain is located receives the input information, the input information is verified, after the verification is completed, the input information is stored in the memory pool, and the hash tree for recording the input information is updated; and then, updating the updating time stamp to the time when the input information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can meet the following formula:
SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET
wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.
Therefore, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and the block head and the block main body are generated to obtain the current block. And then, the node where the block chain is located respectively sends the newly generated blocks to other nodes in the block chain network where the newly generated blocks are located according to the node identifications of the other nodes in the block chain network, the newly generated blocks are verified by the other nodes, and the newly generated blocks are added to the block chain stored in the newly generated blocks after the verification is completed.
The intelligent contract can be operated on the nodes of the block chain network, the intelligent contract is realized by codes executed when a certain condition is met, developers can define contract logic through a programming language, issue the contract logic to the block chain (intelligent contract registration), and call keys or other events to trigger execution according to the logic of contract terms to complete the contract logic and simultaneously provide the functions of upgrading and cancelling the intelligent contract.
Based on the data processing system shown in fig. 1A, an embodiment of the present invention provides a data processing scheme. In this data processing scheme, the user terminal 102 may obtain transaction data submitted by the decentralized application, the transaction data having a data format of a first format. The first format may be a data format supported by a programming language used by the decentralized application. The user terminal 102 converts the data format of the transaction data to obtain the transaction data in a target format, where the target format includes a binary format. For example, the target format may be a protobuf format. The protobuf format may also be abbreviated as pb format. The ProtoBuf herein can also be written as ProtoBuf, and its corresponding english full name can be Protocol Buffer, and its corresponding abbreviation can be PB. That is, the PB format may refer to a PB format. The user terminal 102 sends the transaction data in the target format to the node 101 of the blockchain network. When receiving the data in the target format sent by the user terminal 102, the node 101 may convert the data format of the transaction data in the target format to obtain the transaction data in a second format, where the second format is a data format supported by the intelligent contract of the node 101, that is, the second format is a data format supported by a programming language used by the intelligent contract. Node 101 may invoke the smart contract to process the transaction data in the second format. In the process, the cross-language communication process between the decentralized application and the intelligent contract is realized through the conversion of the target format, the data volume transmitted in the cross-language communication process is reduced, and compared with a json-based method in the prior art, the accuracy of data conversion can be improved due to the fact that the target format comprises a binary format.
The data processing scheme provided by the embodiment of the invention is explained below by taking a scene that a user purchases a game item as an example.
In one application scenario, user a installs DApp1 on a smartphone, DApp1 is a gaming application using JAVA as the programming language, and C + + as the programming language used by the smart contract for node 101. User a may enter the play item purchase page of DApp1, shown in fig. 1D, and may select a play item included in the play item purchase page and click a purchase button corresponding to the play item. After the user clicks the buy button, the smartphone may detect a purchase request submitted by DApp1 for a game item, the purchase request having a data format that is in a first format, that is, a JAVA-supported data format. The smartphone can convert the data format of the purchase request to obtain a purchase request in a PB format, and send the purchase request in the PB format to the node 101. After receiving the purchase request in the PB format, the node 101 may convert the data format of the purchase request in the PB format to obtain the purchase request in the second format, where the second format is a data format supported by the intelligent contract of the node 101, that is, the second format is a data format supported by C + +. Node 101 may invoke a smart contract to execute game item purchase logic according to the purchase request.
It should be noted that the embodiment of the present invention may be applied to other application scenarios besides the above application scenario, and the embodiment of the present invention is not listed here.
It should be further noted that, in addition to being executed by the user terminal, the data processing scheme according to the embodiment of the present invention may also be executed by a service device capable of communicating with the blockchain network, for example, the service device may be a centralized service device. The decentralized application may be run on the service device.

In an embodiment, the data to be sent to the node of the blockchain network may specifically refer to data that needs to be stored or processed by the node of the blockchain network.

In one embodiment, the user terminal may obtain the transaction data submitted by the decentralized application upon detecting the transaction data submitted by the decentralized application.
S202, converting the data format of the transaction data to obtain the transaction data in a target format, wherein the target format comprises a binary format.
In step S201 to step S202, the user terminal may obtain the transaction data submitted by the decentralized application, and convert the data format of the transaction data to obtain the transaction data in the target format. Because the target format comprises a binary format, compared with a json format mode adopted in the prior art, the data volume transmitted in the cross-language communication process of decentralized application and intelligent contracts can be reduced by adopting the target format mode in the embodiment of the invention.
In an embodiment, the process of converting the data format of the transaction data by the user terminal to obtain the transaction data in the target format may be that the user terminal converts the data format of the transaction data according to a preset first format conversion rule to obtain the transaction data in the target format.

Wherein the serialization tool library of the decentralized application may include conversion rules between the data in the first format and the data in the target format. Specifically, the user terminal may invoke a conversion rule between data in the first format and data in the target format included in the serialization tool library of the decentralized application, and perform serialization processing on the transaction data to obtain serialized data corresponding to the transaction data. In one embodiment, when the target format is a PB format, the serialization tool library may be a PB library. That is, when the target format is pb format, the sequencing tool library may be a protbufb library, i.e., a pb library.

The user terminal may send the transaction data in the target format to a node of the blockchain network. The node may receive the transaction data in the target format and convert the data format of the transaction data in the target format to obtain transaction data in a second format.
In one embodiment, it is contemplated that the user terminal may run multiple decentralized applications that may correspond to different blockchain networks. To accurately transmit data, the user terminal may determine the blockchain network to which the decentralized application corresponds, and then transmit the transaction data in the target format to the nodes of the blockchain network.
In one embodiment, the user terminal may include a profile corresponding to the decentralized application. The user terminal may determine the blockchain network corresponding to the decentralized application according to the information of the blockchain network included in the configuration file of the decentralized application, and then send the transaction data in the target format to the node of the blockchain network.
In one embodiment, in addition to converting the data format of the transaction data submitted by the distributed application through steps S201 to S203, the user terminal may further perform the following operations: the user terminal receives target data in a target format sent by a node, wherein the target data in the target format is obtained by converting the data format of the target data in the second format by the node; the user terminal converts the data format of the target data in the target format to obtain the target data in the first format. The target data refers to any one or more data to be sent to the user terminal. For example, the target data may be a query result obtained by the node in response to a data query request sent by the user terminal.
In one embodiment, the user terminal may send a data query request to the node, and receive a query result in a target format sent by the node in response to the data query request, where the query result in the target format is obtained by converting the data format of the query result in the second format by the node; and the user terminal converts the data format of the query result in the target format to obtain the query result in a first format, wherein the first format is a data format supported by the decentralized application. The process is further described below in connection with operations performed by the nodes.
In one embodiment, the user terminal may send a data query request to the node, and the node may obtain a query result in response to the data query request, where the query result is in the second format. In one embodiment, a node may obtain query results from a blockchain in response to the data query request. The node can convert the data format of the query result to obtain the query result in the target format. That is, the query result in the target format is obtained by converting the data format of the query result in the second format by the node. The node may send the query result in the target format to the user terminal. The user terminal can receive the query result in the target format sent by the node responding to the data query request, and convert the data format of the query result in the target format to obtain the query result in the first format.
In an embodiment, the process of converting the data format of the target data in the target format by the user terminal to obtain the target data in the first format may call the serialization tool library of the decentralized application to perform deserialization processing on the target data in the target format for the user terminal to obtain deserialization data corresponding to the target data in the target format; and the user terminal takes the deserialized data corresponding to the target data in the target format as the target data in the first format obtained after the data format conversion of the target data in the target format.

In one embodiment, the second format conversion rule may include a rule set according to a serialization toollibrary. When the second format conversion rule includes a rule set according to the serialization tool library, the user terminal converts the data format of the transaction data in the target format according to a preset second format conversion rule, and a process of obtaining the transaction data in the second format may be as follows: and the node calls a serialization tool library of the node to perform deserialization processing on the transaction data in the target format to obtain deserialized data, and the deserialized data is used as the transaction data in the second format obtained after the data format of the transaction data in the target format is converted. Wherein the serialization tool library of the node may include conversion rules between the data in the second format and the data in the target format. Specifically, the user terminal may invoke a conversion rule between data in the second format and data in the target format included in the serialization tool library of the node, and perform deserialization processing on the transaction data in the target format to obtain deserialized data. In one embodiment, when the target format is a PB format, the serialization tool library may be a PB library. That is, when the target format is pb format, the sequencing tool library may be a protbufb library, i.e., a pb library.
In one embodiment, in addition to the node being able to convert the data format of the transaction data in the target format through steps S301 to S303, the node may perform the following operations: and the node acquires the target data in the second format, converts the data format of the target data to obtain the target data in the target format, and sends the target data in the target format to the user terminal. The target data may refer to any one or more data to be transmitted to the user terminal. For example, the target data may be a query result obtained by the node in response to a data query request.
In one embodiment, a node may receive a data query request sent by a user terminal; the node responds to the data query request to acquire a query result in a second format from the block chain; converting the data format of the query result by the node to obtain a query result in a target format; and the node sends the query result in the target format to the user terminal so that the user terminal converts the data format of the query result in the target format to obtain the query result in the first format, wherein the first format is the data format supported by the decentralized application. This process will be further explained below in connection with operations performed by the user terminal.
In one embodiment, the user terminal may send a data query request to the node, and the node may obtain a query result in response to the data query request, where the query result is in the second format. For example, a node may obtain query results from a blockchain in response to the data query request. The node can convert the data format of the query result to obtain the query result in the target format. That is, the query result in the target format is obtained by converting the data format of the query result in the second format by the node.
