Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, the method for inter-blockchain communication of the present invention is described below with reference to fig. 1 to 4, and includes:
Wherein the source chain is a blockchain of a different architecture than the target chain. For example, the source chain and the target chain may be a block chain of Fabric architecture, a block chain of ethernet architecture, a block chain of EOS network architecture, a block chain of fsco BCOS architecture, and the like, respectively. So long as the source chain is a blockchain of a different architecture than the target chain.
Various transactions are conducted on the source chain, including transactions between homogeneous blockchains and heterogeneous blockchains. The target chain obtains a plurality of transaction data by listening to transactions of the source chain. Specifically, the embodiment of the invention can obtain a plurality of transaction data based on the transaction of the monitoring source chain of the monitoring service. The transaction of the snoop source chain is implemented by a snoop service of, for example, servletContextListener, httpSessionListener and servletrequestListener, to obtain a plurality of transaction data. Specifically, the transaction data includes a transaction hash value, a block ID, a block age, a source chain ID, a destination chain ID, a transaction fee, and the like.
In one embodiment, listening to transactions of a source chain for a plurality of transaction data specifically includes: and obtaining a plurality of transaction data based on the transactions of the WebSocket monitoring source chain. The message sent by the server monitoring the source chain can be realized by monitoring the transaction of the source chain through the WebSocket and only opening a WebSocket service on the target chain. The embodiment of the invention can realize the monitoring of a plurality of transaction data of the source chain more simply and efficiently through the WebSocket.
In addition, when the node of the source chain changes, the original monitoring is stopped, the address is updated, and the monitoring is restarted.
The target chain screens the transaction data based on the cross-chain piece to obtain target transaction data representing the transaction needing to be performed with the cross-chain, and shields the transaction which does not need to be performed with the cross-chain transaction.
The target transaction data at least comprises a transaction hash value, a source chain ID, a target chain ID and transaction information.
The transaction hash value is a transaction number on the blockchain that can be queried over the blockchain network if the transaction is successful. The source chain ID represents the identity of the source chain. The target chain ID represents an identification of the target chain ID. Wherein the source chain ID and the destination chain ID may be represented by a combination of letters and numbers, respectively. For example, the source strand ID is 0gd9fgdh052 and the target strand ID is 0rh9tjn063. The transaction information includes transaction value, transaction status (success or failure), transaction work fee, and transaction remarks. The transaction remarks may record information about the transaction via text information, such as the sender, receiver, and value of the transaction, etc. of the transaction remarks.
Specifically, screening the plurality of transaction data based on the cross-link condition to obtain target transaction data representing the cross-link transaction, including: and determining that the transaction data comprises the target chain ID or the target chain association information, and determining that the transaction data is the target transaction data which needs to carry out the cross-chain transaction.
When the monitored transaction data includes the target link ID, which indicates that the transaction is to be performed to the target link, the monitored transaction data is the target transaction data for which the cross-link transaction is required. Alternatively, when the transaction remark description included in the monitored transaction data is a transaction to be transacted to the target chain, for example, the transaction remark includes "transaction to target chain ID is 0rh9tjn 063" in the transaction remark, then the monitored transaction data is target transaction data for which a cross-chain transaction is required. And identifying target transaction data requiring transaction to the target chain for cross-chain transaction in the source chain by identifying the target chain ID or target chain association information in the transaction data.
After the transaction screening, the obtained target transaction data needing to be subjected to cross-chain transaction is subjected to target chain call relay service interface and is submitted to relay service for processing. The parameter format of the source chain is converted into the parameter format of the target chain. For example, the source chain is a block chain based on Fabric architecture and the target chain is a block chain based on ethernet architecture. At this time, the format of the parameters of the blockchain of the Fabric architecture needs to be converted into the format of the parameters of the blockchain of the ethernet architecture, so that the cross-chain transaction can be performed.
And 500, calling a relay service to send the target transaction data to an adapter tool matched with the target chain for transaction processing.
After the step of converting the parameter format of the source chain of transaction information into the parameter format of the target chain, the target chain invokes the relay service to send the target transaction data to the target chain-matched adapter tool for transaction processing.
It should be noted that, the adapter tool corresponding to the target chain is preconfigured. The blockchains of different architectures have matched developer Tools, such as Fabric has corresponding Fabric-sdk Tools, ethernet has corresponding web3.js Tools, EOS network has corresponding EOS Tools, fsco BCOS has corresponding BCOS-sdk, etc. For example, when the target chain is an ethernet type blockchain, the corresponding adapter tool is a web3.js tool. And the target chain calls the relay service to send the target transaction data to the adapter tool matched with the target chain for transaction processing.
Screening a plurality of transaction data based on the cross-chain piece to obtain target transaction data representing the cross-chain transaction; calling a relay service to convert the parameter format of a source chain of transaction information into the parameter format of a target chain; and then, the relay service is called to send the target transaction data to the adapter tool matched with the target chain for transaction processing. Therefore, the embodiment of the invention provides the unified relay service of the cross-region block chain based on the screening and conversion of the target transaction data and the transaction processing of the adapter tool sent to the target chain, and realizes the communication and the interoperation between isomorphic or heterogeneous chains. The blockchains participating in the cross-chain communication in the embodiment of the invention do not need to be modified or upgraded, can be quickly accessed into a cross-chain network with low cost, and improves the communication efficiency and compatibility between different bottom blockchains.
In other aspects of the embodiments of the present invention, referring to fig. 2, before step 400, calling the relay service to convert the parameter format of the source chain of the transaction information into the parameter format of the target chain, the method further includes:
Under the condition that the verification function is started, the target chain calls a relay service to determine the source chain type of the target transaction data; invoking a relay service to determine the source chain type of the target transaction data; and then controlling the relay service to verify the target transaction data based on the verification rule.
Specifically, the target chain stores verification rules corresponding to blockchains of different architectures. For example, the target chain stores verification rules corresponding to the blockchain of Fabric architecture, the blockchain of ethernet architecture, the blockchain of EOS network architecture, the blockchain of fsco BCOS architecture, and the like. The verification rule specifically comprises verification of transaction signature, block information, consensus information and the like by the block chain infrastructure.
For example, verifying the transaction signature of the cross-chain transaction based on the pre-stored corresponding certificate of the source chain, and also verifying whether the state information and the consensus information in the block are correct; an intelligent contract for authentication may also be invoked for authentication.
Specifically, the source chain ID in the target transaction data represents a blockchain of which the type is Fabric, and is based on a verification rule corresponding to the blockchain of which the Fabric is stored in the target chain. The target chain verifies the transaction signature, verifies whether the state information in the block is correct or not and verifies whether the consensus information is correct or not based on a block chain corresponding certificate of a pre-stored Fabric architecture; or by a special validation contract corresponding to the blockchain of the Fabric architecture.
In the embodiment of the invention, the subsequent parameter conversion operation is executed through the verification rule. The verification rule is determined based on the source chain type to verify the transaction information in the target transaction data, so that the data accuracy and the safety in the target transaction data are improved, and the success rate of cross-chain communication is improved.
It should be noted that when verification fails, the cross-chain transaction is stopped.

The embodiment of the invention provides an interface for the relay service, a user sends out a query instruction through electronic equipment (keyboard, mouse or touch operation), and the target chain responds to the query instruction and calls the relay service to query the transaction hash value and the transaction execution result of the transaction processing by the adapter tool. For example, in the embodiment of the present invention, the source chain a will read the state and information of the target chain B, and the state and information of the B chain is used as the trigger condition for execution. And carrying out private key signature by using the address of the source chain A to obtain a signature, combining the signature with the transaction, carrying out hash value operation to obtain a transaction hash value, then spreading the transaction hash value to the target chain, and inquiring the transaction hash value through an inquiry instruction if the transaction is successful. In addition, the transaction hash value and the transaction execution result of the transaction processing can be queried by calling the relay service. The transaction execution results include success and failure.
It should be noted that, the transaction hash value and the transaction execution result of the transaction processing performed by the adapter tool may be displayed in a visual manner, for example, by an electronic device display.
