Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying 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 data sharing from node to node. The blockchain network may include a plurality of nodes 101, and the plurality of nodes 101 may refer to individual clients in the blockchain network. Each node 101 may receive input information while operating normally and maintain shared data within the blockchain network based on the received input information. In order to ensure information intercommunication in the blockchain network, information connection can exist between every two nodes 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 sending transaction data in a target format to nodes in the blockchain network. Wherein the user terminal 102 has a decentralised application (Decentralized Application, DApp) running thereon. The decentralised application may also be referred to as a distributed application. For example, the decentralizing application may be a game application, and embodiments of the present invention are not limited. The user terminals 102 include, but are not limited to, smart terminals such as smartphones, tablets, desktops, 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.
For each node in the blockchain network, the node identification corresponding to the node identification is provided, and each node in the blockchain network can store the node identifications of other nodes in the blockchain network so as to broadcast the generated blocks to other nodes in the blockchain network according to the node identifications of the other nodes. Each node can maintain a node identification list shown in the following table, and the node names and the node identifications are correspondingly stored in the node identification list. The node identifier may be an IP (Internet Protocol, protocol of interconnection between networks) address, and any other information that can be used to identify the node, and the IP address is only illustrated in table 1.
| Node name | Node identification |
| Node 1 | 117.114.151.174 |
| Node 2 | 117.116.189.145 |
| … | … |
| Node N | 119.123.789.258 |
Each node in the blockchain network stores one and the same blockchain. The blockchain is composed of a plurality of blocks, referring to fig. 1B, the blockchain is composed of a plurality of blocks, the starting block comprises a block head and a block main body, the block head stores an input information characteristic value, a version number, a time stamp 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 father 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 father 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 are associated with the block data stored in the father block, and the safety of the input information in the block is ensured.
When each block in the blockchain is generated, referring to fig. 1C, when the node where the blockchain is located receives input information, checking the input information, after the checking is completed, storing the input information into a memory pool, and updating a hash tree used for recording the input information; then, updating the update time stamp to the time of receiving the input information, trying different random numbers, and calculating the characteristic value for a plurality of 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 eigenvalue algorithm used to calculate eigenvalues; version (version number) is version information of the related block protocol in the block chain; the prev_hash is the block header characteristic value of the parent block of the current block; the merkle_root is a characteristic value of input information; ntime is the update time of the update timestamp; the nbits is the current difficulty, is a fixed value in a period of time, and is determined again after exceeding a fixed period of time; x is a random number; TARGET is a eigenvalue threshold that can be determined from nbits.
Thus, when the random number meeting the formula is calculated, the information can be correspondingly stored to generate the block head and the block main body, and the current block is obtained. And then, the node where the blockchain is located sends the newly generated blocks to other nodes in the blockchain network where the newly generated blocks are located according to the node identifications of other nodes in the blockchain network, the other nodes verify the newly generated blocks, and the newly generated blocks are added into the blockchain stored in the newly generated blocks after the verification is completed.
The intelligent contract is a code implementation for executing when a certain condition is met, a developer can define contract logic through a programming language, issue the contract logic to a blockchain (intelligent contract registration), call a key or trigger execution according to the logic of contract clauses to complete the contract logic, and simultaneously provide functions of upgrading and logging off 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 de-centralized application, the transaction data having a data format that is the first format. The first format may be a data format supported by a programming language used by the de-centralized application. The user terminal 102 converts the data format of the transaction data to obtain transaction data in a target format, the target format comprising a binary format. For example, the target format may be a protobuf format. Wherein, the protobuf format can be abbreviated as pb format. The ProtoBuf may be written as ProtoBuf, the corresponding english full name may be Protocol Buffer, and the corresponding shorthand may be PB. That is, PB format may refer to PB format. The user terminal 102 sends 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 transaction data in a second format, where the second format is a data format supported by the smart contract of the node 101, that is, the second format is a data format supported by a programming language used by the smart contract. Node 101 may invoke the smart contract to process the transaction data in the second format. The process realizes the process of cross-language communication between the decentralised application and the intelligent contract through the conversion of the target format, reduces the data quantity transmitted in the cross-language communication process, and can improve the accuracy of data conversion compared with a json-based method in the prior art because the target format comprises a binary format.
The data processing scheme provided by the embodiment of the invention is described below by taking a scene that a user purchases game props as an example.
In one application scenario, user a installs DApp1 on a smart phone, DApp1 is a game application that uses the programming language JAVA and node 101's smart contract uses the programming language c++. User A may enter the game prop purchase page of DApp1 as shown in FIG. 1D, and may select a game prop included in the game prop purchase page, and click a purchase button corresponding to the game prop. After the user clicks the purchase button, the smart phone may detect a purchase request submitted by DApp1 for the game prop, where the data format of the purchase request is in the first format, that is, the first format is a JAVA-supported data format. The smart phone may convert the data format of the purchase request to obtain a purchase request in PB format, and send the purchase request in PB format to the node 101. After receiving the PB format purchase request, the node 101 may convert the data format of the PB format purchase request to obtain a purchase request in a second format, where the second format is a data format supported by the smart 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 in accordance with the purchase request.
It should be noted that, the embodiments of the present invention may be applied to other application scenarios besides the application scenarios described above, and the embodiments of the present invention are not limited to this.
It should be further noted that, in addition to being executed by the ue, the data processing scheme according to the embodiments 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 service device may have the decentralized application running thereon.

In step S201-step S202, the user terminal may obtain transaction data submitted by the decentralized application, and convert the data format of the transaction data to obtain transaction data in a target format. Because the target format comprises a binary format, compared with the json format adopted in the prior art, the embodiment of the invention adopts the target format mode, so that the data volume transmitted in the cross-language communication process of the decentralizing application and the intelligent contract can be reduced.
In one 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 de-centralization application may include conversion rules between data in the first format and data in the target format. Specifically, the user terminal may invoke a conversion rule between the data in the first format and the data in the target format included in the serialization tool library of the decentralization 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 serialization tool library may be a protbufb library, i.e., pb library.

In one embodiment, it is contemplated that a user terminal may run multiple decentralised applications that may correspond to different blockchain networks. To accurately transmit data, the user terminal may determine a blockchain network to which the de-centralized application corresponds and then transmit transaction data in the target format to nodes of the blockchain network.
In one embodiment, the user terminal may include a profile corresponding to the de-centralized application. The user terminal may determine a blockchain network corresponding to the decentralised application according to the blockchain network information included in the configuration file of the decentralised application, and then send the transaction data in the target format to a node of the blockchain network.

Wherein 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 a data format of the query result in the second format by the node; 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 decentralizing application. This process will be further described in connection with the 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, the query result being 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 may receive a query result in a target format sent by the node in response to the data query request, and convert a data format of the query result in the target format to obtain a query result in a first format.
In one 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 deserialization application for the user terminal to perform deserialization processing on the target data in the target format to obtain the deserialized data corresponding to the target data in the target format; the user terminal takes the reverse-sequence 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.

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 the preset second format conversion rule, and the process of obtaining the transaction data in the second format may be as follows: 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 the second format data and the target format data included in the serialization tool library of the node, and perform deserialization processing on the target format transaction data to obtain deserialized data. In one embodiment, when the target format is a PB format, the serialization tool library may be a PB library.

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 the 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 blockchain; the node converts the data format of the query result to obtain a query result in a target format; 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, and the first format is the data format supported by the decentralizing application. This process will be further described in connection with the 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, the query result being 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.
