Fig. 1 is a block chain system scene diagram according to an exemplary embodiment.
In the scenario illustrated in fig. 1, the blockchain system may include a plurality of blockchains, an intermediary, and a management platform. The intermediate device may be a device with a routing function, such as a gateway, and the management platform may be a device with computing and processing capabilities, a platform, a server, or a device cluster. The user's device may communicate with an intermediate device that may communicate with the management platform and each blockchain, respectively.
In particular, the user's device may send a transaction request to the intermediary device, the transaction request being used to initiate the target transaction. The target transaction may be a normal non-contract transaction, a transaction that deploys a smart contract, or a transaction that processes a target smart contract. The processing target intelligent contract may be an upgrading target intelligent contract, a freezing or unfreezing target intelligent contract, a destroying target intelligent contract, a calling target intelligent contract, and the like.
The intermediate device responds to the transaction request and sends indication information to the management platform to indicate the management platform to determine a target block chain for executing the target transaction in the plurality of block chains. After determining the target block chain, the management platform acquires first information of the target block chain and returns the first information to the intermediate device. The first information of the target block chain may be information such as an address of the target block chain or an identification of the target block chain. After receiving the first information, the intermediate device may initiate a target transaction to the target blockchain according to the first information. The nodes of the target blockchain process the target intelligent contract by executing the target transaction.
The embodiments provided in the present specification will be described in detail with reference to specific examples.
As shown in fig. 2, fig. 2 is an interactive flow diagram illustrating a method of initiating a transaction in a blockchain system in accordance with an exemplary embodiment. The block chain system comprises a plurality of block chains, intermediate equipment and a management platform, and the method comprises the following steps:
in step 201, the intermediary device receives a transaction request from a device of a user to initiate a target transaction.
In this embodiment, the intermediary device may receive a transaction request from the user's device for initiating the target transaction. The device of the user may be a terminal device held by the user, and as will be understood by those skilled in the art, the terminal device may be a mobile terminal device such as a smart phone, a smart wearable device, a tablet computer, a notebook computer, a desktop computer, an electronic payment device, and the like. The target transaction may be a common non-contract transaction, a transaction for deploying an intelligent contract, or a transaction for processing an intelligent contract. It is to be understood that the present embodiment is not limited to a particular type of targeted transaction.
In step 203, the intermediate device sends indication information to the management platform based on the transaction request to instruct the management platform to determine a target block chain of the plurality of block chains to execute the target transaction.
In step 205, the management platform determines a target block chain for executing the target transaction under the indication of the indication information.
In this embodiment, the transaction request may carry information for initiating the target transaction, and specifically may include related information related to a target block chain for executing the target transaction. For example, the related information may be information of the user, or may also be information of a target intelligent contract to be processed, and the like. The intermediate device may obtain the relevant information from the transaction request and send indication information to the management platform based on the relevant information to instruct the management platform to determine a target blockchain of the plurality of blockchains to execute the target transaction.
For example, in one implementation, the target transaction is a normal, non-contract transaction, or a transaction that deploys smart contracts. The intermediate device may obtain information of the user from the transaction request and send indication information to the management platform to instruct the management platform to determine a target block chain for performing the target transaction based on the information of the user. The management platform may search the block chain associated with the user information from the pre-stored data as the target block chain under the instruction of the instruction information.
In another implementation, the target transaction is a transaction that processes a smart contract. The intermediate device may obtain information of a target intelligent contract to be processed from the transaction request and send indication information to the management platform to instruct the management platform to determine a target block chain for executing the target transaction based on the information of the target intelligent contract. The management platform can search the block chain associated with the information of the target intelligent contract from the pre-stored data under the indication of the indication information to serve as the target block chain.
In step 207, the management platform returns the first information of the target blockchain.
In this embodiment, after determining the target block chain, the management platform returns the first information of the target block chain to the intermediate device. The first information of the target block chain may be identification information of the target block chain, or address information of the target block chain, and it can be understood that the specific type of the first information is not limited in this embodiment.
In step 209, the intermediary initiates a target transaction to the target blockchain according to the first information.
In this embodiment, the intermediate device may initiate a target transaction to the target blockchain according to the first information of the target blockchain. Specifically, in an implementation manner, a private key of the device of the user may be managed by the intermediate device, and in this scenario, a transaction request sent by the device of the user to the intermediate device may carry information used for generating a target transaction, and the like. The intermediate device may generate a target transaction based on the transaction request, perform a signature using a private key of the device of the user, and initiate the target transaction to the target block chain according to first information after receiving the first information of the target block chain.
In another implementation manner, the private key of the device of the user is managed by the device itself, and in this scenario, the device of the user may generate and sign the target transaction in advance, and then send a transaction request carrying the signed target transaction to the intermediate device. After receiving the first information of the target blockchain, the intermediate device may directly forward the target transaction in the transaction request to the target blockchain according to the first information.
In the method for initiating a transaction in a blockchain system provided in the above embodiments of the present specification, a transaction request for initiating a target transaction is received from a device of a user through an intermediate device, a management platform is instructed to determine a target blockchain for executing the target transaction in a plurality of blockchains, the management platform returns first information of the target blockchain to the intermediate device, and the intermediate device initiates the target transaction to the target blockchain according to the first information. Therefore, on the premise of improving the service throughput of the block chains through the block chains, the block chains in the block chain system are abstracted into one chain, the complexity of the bottom multi-chain is shielded for a user, and the user does not need to pay attention to a specific block chain corresponding to the service in the process of using the block chain service.
As shown in FIG. 3, FIG. 3 illustrates an interactive flow diagram of a method for initiating a transaction in another blockchain system according to an exemplary embodiment describing the process of initiating a transaction to deploy a smart contract, which may include the steps of:
in step 301, an intermediary device receives a transaction request from a device of a user to initiate a target transaction to deploy a smart contract.
In step 303, the intermediary device obtains the user's information from the transaction request.
In step 305, the intermediate device sends indication information to the management platform based on the information of the user to instruct the management platform to determine a target block chain for executing the target transaction in the plurality of block chains according to the information of the user.
In this embodiment, the intermediate device may receive a transaction request from a device of a user, where the transaction request is used to initiate a target transaction for deploying the smart contract, and the transaction request may carry information of the user. The information of the user may include, but is not limited to, an identification of the user, a characteristic of the user, an attribute of the user, an area to which the user belongs, and the like. The intermediate device may obtain information of the user from the transaction request, and send instruction information to the management platform based on the information of the user to instruct the management platform to determine a target block chain for executing a target transaction among the plurality of block chains according to the information of the user.
In step 307, under the instruction of the instruction information, the management platform determines the block chain corresponding to the user as the target block chain according to the information of the user.
In this embodiment, each user may be previously assigned to a different block chain according to the feature, attribute, belonging area, or the like of each user, and the association relationship between the information of each user and each corresponding block chain may be stored in the database of the management platform. After receiving the indication information sent by the intermediate device, the management platform may search, under the indication of the indication information, a block chain having an association relationship with the user from the database according to the information of the user, and use the block chain corresponding to the determined user as a target block chain.
For example, each user may be assigned to a different block chain according to the user belonging area, specifically, a user belonging to area a is assigned to block chain 1, a user belonging to area B is assigned to block chain 2, and a user belonging to area C is assigned to block chain 3. Then, the following relationships are stored in the database of the management platform: the association relationship between the belonging area a and the block chain 1, the association relationship between the belonging area B and the block chain 2, and the association relationship between the belonging area C and the block chain 3.
And the intermediate equipment responds to the received transaction request, acquires the information of which the area to which the user belongs is A from the transaction request and sends indication information to the management platform. Under the indication of the indication information, the management platform searches the block chain 1 having an association relationship with the area A from the database based on the information that the area A to which the user belongs, thereby determining that the block chain corresponding to the user is the block chain 1, and taking the block chain 1 as a target block chain.
In step 309, the management platform returns the first information of the target blockchain.
In step 311, the intermediary initiates a target transaction to the target blockchain according to the first information.
In step 313, after the target transaction is successfully executed, the intermediary instructs the management platform to associate the deployed smart contract with the target blockchain.
In this embodiment, the blockchain node of the target blockchain receives and executes the target transaction initiated by the intermediate device, and when it is determined that the target transaction is successfully executed, returns a receipt of the target transaction to the intermediate device. The intermediate device, in response to the receipt, instructs the management platform to associate the deployed intelligent contract with the target blockchain. In particular, the management platform may store an identification of the deployed intelligent contract and an identification of the target blockchain in association in a database.
It should be noted that, for the same steps as in the embodiment of fig. 2, details are not repeated in the embodiment of fig. 3, and related contents may refer to the embodiment of fig. 2.
In the method for initiating a transaction in a blockchain system provided by the above embodiment of the present specification, in a process of initiating a transaction for deploying an intelligent contract, an intermediate device receives, from a device of a user, a transaction request for initiating a target transaction for deploying the intelligent contract, acquires information of the user from the transaction request, and sends, based on the information of the user, indication information to a management platform to indicate the management platform to determine, according to the information of the user, a blockchain corresponding to the user as a target blockchain, and returns first information of the target blockchain. And the intermediate equipment initiates a target transaction to the target block chain according to the first information. After the target transaction is successfully executed, the intermediate device instructs the management platform to associate the deployed intelligent contract with the target blockchain. In this embodiment, the intermediate device may obtain the information of the user and instruct the management platform to determine the blockchain corresponding to the user as the target blockchain for executing the target transaction according to the information of the user, so that the user does not need to pay attention to a specific blockchain corresponding to a service in the process of using the blockchain service, thereby improving the service efficiency and the service quality of the blockchain system.
It should be noted that, in some cases of deploying intelligent contracts, if other related intelligent contracts are also involved in the deployed intelligent contracts, the intelligent contracts to be deployed may also be deployed on the block chain of the related intelligent contracts. The blockchain of the associated smart contract is not necessarily the blockchain to which the information of the user corresponds. The management platform may provide an interface through which a user may view an address of a blockchain associated with the intelligent contract and deploy the intelligent contract to be deployed onto the blockchain associated with the intelligent contract.
FIG. 4, as shown in FIG. 4, illustrates a flow diagram of a method for initiating a transaction in another blockchain system according to an exemplary embodiment detailing the process of initiating a transaction for processing a target smart contract, which may include the steps of:
in step 401, the intermediary receives a transaction request from a device of a user to initiate a target transaction to process a target smart contract.
In step 403, the intermediary obtains second information of the target smart contract from the transaction request.
In step 405, the intermediary device sends indication information to the management platform based on the second information to instruct the management platform to determine a target blockchain for performing the target transaction among the plurality of blockchains according to the second information.
In this embodiment, the processing target intelligent contract may be an upgrading target intelligent contract, a freezing or unfreezing target intelligent contract, a destroying target intelligent contract, a calling target intelligent contract, or the like. The second information of the target intelligent contract may be carried in the transaction request sent by the device of the user to the intermediate device, and the second information may be identification information of the target intelligent contract, and the like.
In this embodiment, the intermediate device may obtain second information of the target intelligent contract from the transaction request, and send indication information to the management platform based on the second information to instruct the management platform to determine, according to the second information, a target block chain of the plurality of block chains for executing the target transaction.
It should be noted that, if other associated intelligent contracts are also involved in the target intelligent contract to be called, the user may search, in advance, addresses of the associated intelligent contracts, contract parameters of the associated intelligent contracts, and the like through an interface provided by the management platform. And recording the address of the associated intelligent contract and the contract parameters of the associated intelligent contract in the target intelligent contract (which can be recorded when the target intelligent contract is deployed, or recorded when the target intelligent contract is upgraded, etc.), so that the associated intelligent contract is used when the target intelligent contract is called.
In step 407, under the instruction of the instruction information, the management platform determines, according to the second information, a block chain corresponding to the target intelligent contract as a target block chain.
In this embodiment, the block chain corresponding to the target intelligent contract is a block chain for deploying the target intelligent contract, and after the target intelligent contract is deployed, the target intelligent contract is associated with the block chain for deploying the target intelligent contract, and the association relationship is stored in the database, so that the management platform can find the block chain corresponding to the target intelligent contract from the database according to the second information, and use the block chain as the target block chain.
In step 409, the management platform returns the first information of the target blockchain.
In step 411, the intermediary determines whether a preset condition is satisfied.
In step 413, the intermediate device initiates a target transaction to the target blockchain according to the first information if it is determined that the preset condition is satisfied.
In this embodiment, each user may be previously assigned to a different block chain according to the feature, attribute, belonging area, or the like of each user, and the association relationship between the information of each user and each corresponding block chain may be stored in the database of the management platform.
Specifically, after receiving a transaction request sent by a device of a user, the intermediate device may obtain information of the user from the transaction request, and instruct the management platform to query the blockchain corresponding to the user based on the information of the user. And the management platform inquires the block chain corresponding to the user from the database based on the information of the user and returns the third information of the block chain corresponding to the user to the intermediate equipment. The third information may be identification information of a block chain corresponding to the user, or address information of the block chain corresponding to the user, and it can be understood that the specific type of the third information is not limited in this embodiment.
The intermediary may determine whether the user corresponds to the target blockchain based on the third information and the first information. Specifically, if the first information and the third information are the same, it is described that the user corresponds to the target block chain. And if the first information is different from the third information, the user does not correspond to the target block chain. And in the case that the user is determined to correspond to the target block chain, determining that a preset condition is met, and initiating a target transaction to the target block chain according to the first information.
In the event that it is determined that the user does not correspond to the target blockchain, it may be further verified whether the user has a target permission to send the target transaction to the target blockchain. Generally, a user has the default authority to send transactions to the user's corresponding blockchain, while for other blockchains, the user may have the pre-empted authority to send transactions to the specified blockchain. After the authority is opened, the account on the designated block chain is established in a transaction form through the gateway, or the account on the designated block chain can be established directly through an interface provided by the management platform.
In particular, it may be verified by looking at the authority table whether the user has a target authority to send a target transaction to the target blockchain. And under the condition that the user is determined to have the target authority, the preset condition can be determined to be met, and the target transaction is sent to the target block chain according to the first information. And under the condition that the user is determined not to have the target authority, refusing to execute the operation of sending the target transaction to the target block chain according to the first information, and simultaneously returning a notification message of refusing to send the target transaction to the equipment of the user.
