And is not particularly limited herein.
With continued reference to FIG. 2, a flow 200 of one embodiment of a blockchain-based data interaction method in accordance with the present disclosure is shown. The data interaction method based on the block chain comprises the following steps:
In this embodiment, after a user establishes a target intelligent contract with other users as participants, the target intelligent contract may be written into a target block chain. In order to enable the user to determine the target intelligent contract in the target blockchain network, the user needs to acquire identification information of the target blockchain. Therefore, an execution subject (for example, the terminal device shown in fig. 1) of the data interaction method based on the blockchain may obtain the identification information of the target blockchain where the target intelligent contract is located from the blockchain network or the like through a wired connection manner or a wireless connection manner.
It should be noted that the wireless connection means may include, but is not limited to, a 3G/4G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a uwb (ultra wideband) connection, and other wireless connection means now known or developed in the future.
In this embodiment, the execution main body (for example, the terminal device shown in fig. 1) may install a general blockchain application in advance, and the execution main body may access the blockchain network in response to a user operating the general blockchain application. Therefore, based on the identification information of the target blockchain acquired in step 201, the execution subject may access the target blockchain in the blockchain network in response to the operation of the user on the general blockchain application, so that the interaction rule information of the target intelligent contract may be acquired from the target intelligent contract deployed on the target blockchain. It should be noted that the interaction rule information may be used to characterize rules for data interaction between the user and the target intelligent contract through the universal blockchain application. The interaction rule information can determine the display form of the target intelligent contract on the execution main body to a certain extent. By way of example, the data interaction rules may include a rule that a user should query relevant data of a target intelligent contract through a general block link (e.g., a rule that queries data by clicking a preset button or inputting a preset rule query keyword, etc.), and a rule that an intelligent contract returns query data (e.g., a rule that returns query data in the form of a table, etc.).
It will be appreciated that the blockchain may typically be written with one or more intelligent contracts, and thus the target blockchain may be written with a plurality of intelligent contracts, and a user may determine the target intelligent contract in which the user participates from the intelligent contracts on the target blockchain when accessing the target blockchain through a general blockchain application installed on the execution subject. If only the target intelligent contract is written in the target block chain, the execution main body can directly access the intelligent contract through the identification information of the target block chain.
In some optional implementation manners of this embodiment, the execution main body may further obtain identification information of a target intelligent contract that a user needs to access while obtaining identification information of the target block chain. Thus, even if multiple intelligent contracts are written on the target blockchain, the user can directly access the target intelligent contract deployed on the target blockchain through the identification information of the target intelligent contract and the general blockchain application. The implementation mode can improve the access speed of the intelligent contract and improve the efficiency of data interaction.
In some optional implementation manners of this embodiment, the execution main body may obtain a generic software installation package of a pre-generated blockchain application, then decompress the generic software installation package, and may install the generic blockchain application on the execution main body. The universal blockchain application can provide functions required by business processing such as state data browsing query of the intelligent contract and intelligent contract transaction execution for the user. Further, the target blockchain may be any blockchain in a blockchain network, the target contract may be any contract on the target blockchain, and it is seen that the universal blockchain application may provide an operating platform of a universal intelligent contract for a user.
In some optional implementations of the embodiment, the interaction rule information of the intelligent contract may be generated before the target intelligent contract is deployed on the target blockchain. The target intelligent contract and the interaction rule information of the target intelligent contract can be deployed on the target block chain at the same time. Therefore, the execution subject can acquire the rule information of the target intelligent contract from the target blockchain through the general blockchain application. The implementation mode binds the interaction rule information of the target intelligent contract and writes the interaction rule information into the block chain, so that the target intelligent contract and the interaction rule information can be simultaneously stored, the storage efficiency is improved, and a user can conveniently and quickly acquire the interaction rule information of the target intelligent contract when interacting with the target intelligent contract.
And 203, performing data interaction with the target block chain based on the interaction rule information and the universal block chain application.
In this embodiment, based on the interaction rule information of the target intelligent contract obtained in step 202, the user may perform data interaction, such as data query, intelligent contract transaction, and the like, with the target blockchain through the general blockchain application installed on the execution subject. Specifically, the executing agent may perform data interaction with a target intelligent contract on a target blockchain according to a rule definition in the acquired interaction rule information.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the data interaction method based on the blockchain according to the present embodiment. In the application scenario of fig. 3, for a target intelligent contract in which a user participates as a participant, after the user installs a general blockchain application on a terminal device, step 301 may be executed to obtain identification information of a target blockchain; then, the terminal device may execute step 302 to obtain interaction rule information of the target intelligent contract from the target blockchain through the installed general blockchain application based on the identification information of the target blockchain; finally, the terminal device may perform step 303 to perform data interaction with the target blockchain based on the acquired interaction rule information and the universal blockchain application installed thereon, as shown in fig. 3.
According to the data interaction method based on the block chain, provided by the embodiment of the disclosure, the interaction rule information of the target intelligent contract is acquired from the target block chain through the pre-installed universal block chain application by acquiring the identification information of the target block chain, and then the data interaction with the target block chain is performed based on the acquired interaction rule information and the universal block chain application, so that a user can perform the data interaction with the target intelligent contract deployed on the target block chain through the installed universal block chain application according to the interaction rule information of the target intelligent contract, the operations of browsing, trading and the like of the user on the intelligent contract can be realized without developing an interaction system of the client and the intelligent contract, and the use cost of the block chain is reduced.
With further reference to FIG. 4, a flow 400 of yet another embodiment of a blockchain-based data interaction method is shown. The flow 400 of the data interaction method based on the blockchain includes the following steps:
step 401, obtaining identification information of a target block chain.
In this embodiment, after a user establishes a target intelligent contract with other users as participants, the target intelligent contract may be written into a target block chain. In order to enable the user to determine the target intelligent contract in the target blockchain network, the user needs to acquire identification information of the target blockchain. Therefore, an execution subject (for example, the terminal device shown in fig. 1) of the data interaction method based on the blockchain may obtain the identification information of the target blockchain where the target intelligent contract is located from the blockchain network or the like through a wired connection manner or a wireless connection manner.
And 402, acquiring interaction rule information of the target intelligent contract from the target block chain through a pre-installed universal block chain application based on the identification information of the target block chain.
In this embodiment, the execution main body (for example, the terminal device shown in fig. 1) may install a general blockchain application in advance, and the execution main body may access the blockchain network in response to a user operating the general blockchain application. Therefore, based on the identification information of the target blockchain acquired in step 401, the execution subject may access the target blockchain in the blockchain network in response to the operation of the user on the general blockchain application, so that the interaction rule information of the target intelligent contract may be acquired from the target intelligent contract deployed on the target blockchain. It should be noted that the interaction rule information may be used to characterize rules for data interaction between the user and the target intelligent contract through the universal blockchain application. The interaction rule information can determine the display form of the target intelligent contract on the execution main body to a certain extent.
Step 403, in response to the operation of the user on the universal blockchain application, generating operation information.
In this embodiment, when the user performs operations such as clicking, browsing, text input, and the like on the universal blockchain application, the execution main body may generate corresponding operation information. Here, the operation information may include transaction information, data acquisition information, and data inquiry information of the target smart contract. The transaction information of the target intelligent contract can be information input by a user to enable the target intelligent contract to execute transaction, and the data acquisition information and the data query information can be information input by the user to enable the target intelligent contract to return acquired data or query data.
Step 404, an access interface of the target block chain provided by the middleware of the universal block chain application is called, the target intelligent contract is accessed through the access interface based on the operation information and the interaction rule information, and operation result data aiming at the target intelligent contract is obtained from the target block chain.
In this embodiment, the universal blockchain application may provide an interface for data acquisition and service data query, such as intelligent contract transaction and data interaction rule information, so that a user may interact with the blockchain network through the universal blockchain application. Based on the operation information generated in step 403, the execution agent may call an access interface of the target blockchain provided by the middleware of the universal blockchain application. Then, the executing body can access the target intelligent contract through the called access interface based on the operation information and the interaction rule information, so that operations such as transaction, data query, data acquisition and the like can be executed on the target intelligent contract according to the operation information. Finally, the execution subject may obtain operation result data for the target intelligent contract from the target blockchain. The operation result data may include a transaction result after transaction is performed according to the transaction information of the target intelligent contract, a data acquisition result obtained by performing data acquisition according to the data acquisition information, and a data query result obtained by performing data query according to the data query information.
Step 405, locally caching the acquired operation result data to display the operation result data to the user.
In this embodiment, based on the operation result data acquired in step 404, the execution main body may locally cache the acquired operation result data, so that the operation result data may be displayed to the user.
In some optional implementations of this embodiment, the execution main body may further listen to the target blockchain through a general blockchain application installed thereon. If the execution main body monitors the target intelligent contract execution transaction event, whether the transaction event is related to the user can be determined based on the user information of the user. If the transaction event is determined to be related to the user, the execution body can locally cache the monitored monitoring information. It will be appreciated that the universal blockchain application may also monitor other events than transaction events, and upon determining that the monitored event is an event associated with a user operating the universal blockchain application, may return the monitored information to the user. According to the implementation mode, the target intelligent contract is monitored through the universal block chain application, so that a user can check the transaction event related to the user in real time, and the user can know the transaction dynamic of the intelligent contract in real time.
In some optional implementation manners of this embodiment, the user may initiate a transaction request to the target intelligent contract through the universal blockchain application, at this time, the execution main body may obtain the transaction parameters in the transaction request, and then the execution main body may send the transaction data to the target blockchain. After receiving the transaction data, the target block chain may execute a transaction event corresponding to the transaction request in the target intelligent contract according to the transaction data and generate a transaction result. The execution agent may obtain a transaction result of the user request transaction from the target blockchain, and store the obtained transaction result locally. Further, the execution main body can also display the transaction result to the user through the universal block chain application. The universal block chain application in the implementation mode is convenient for a user to request a transaction from a target intelligent contract, and a transaction result can be quickly acquired and displayed through the universal block chain application.
In some optional implementations of this embodiment, the execution subject may obtain the transaction result by: obtaining verification and consensus results of the target intelligent contract from the target block chain; in response to determining that the target intelligent contract is validated and agrees, a trading result for the target intelligent contract may be obtained. The realization mode can send the transaction result of the intelligent contract after determining that the target intelligent contract passes the verification and achieves the consensus, thereby improving the safety of the intelligent contract.
In some optional implementations of this embodiment, the operation performed by the user on the universal blockchain application may be a data query operation. At this time, the execution main body may receive a data query request of a target intelligent contract sent by the user, and the target block chain may select data corresponding to the data query request according to interaction rule information of the target intelligent contract after acquiring the data query request. The execution agent may obtain the selected data from the target blockchain and present the selected data to the user through the universal blockchain application according to the interaction rule information. The implementation mode provides a general method for querying data through the general block chain application, intelligent contract participants do not need to separately develop related systems, and the use cost of the block chain is reduced.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the data interaction method based on blockchain in this embodiment highlights the step of performing data interaction with the target blockchain based on the interaction rule information and the common blockchain application. Therefore, the embodiment provides the operation method of the user on the target intelligent contract through the universal block chain application, and the operation result data is displayed through the universal block chain application after the operation result data is acquired.
