Description
Technical Field
The present application relates to the field of blockchain technologies, and in particular, to a method and an apparatus for blockchain cross-chain transaction, a computer device, and a storage medium.
Background
With the development of the blockchain, on one hand, a plurality of blockchains with different architectures emerge; on the other hand, the application of other block chains in commerce is continuously enriched, such as financial products in public chain and company business in alliance chain. The cross-chain scenes derived on the basis of the block chains have different cross-chain requirements, and all scenes are difficult to apply in a single cross-chain mode.
In the existing chain-crossing technology, a relay chain or notary mechanism is often adopted. In the notary mechanism, a trusted third party is needed between two block chains needing to be linked, and the trusted third party is an entity or a union formed by a plurality of entities. The third party verifies the cross-chain transaction sent by one blockchain and submits the cross-chain transaction to another blockchain. The problems of different block chain transaction formats, different transaction verification modes, atomicity of cross-chain transaction and the like are all responsible for the notary. Another common is a relay chain mechanism, which does not require a trusted third party, but rather employs an entire blockchain exclusively for authentication and forwarding of cross-chain transactions.
In the two schemes, the two schemes are only suitable for specific scenes, for example, the notary mode can improve the efficiency of cross-chain transaction under the condition of high credibility, and the scheme is simple. The relay chain mechanism can deal with chain-crossing two parties or even multiple parties with insufficient mutual trust for chain-crossing, but the chain-crossing technology is complex for a scene with high trust degree, and the relay chain mechanism cannot be well adapted to a scene with an authoritative center.
Aiming at the problem that the adaptability of a cross-chain transaction scheme in the related technology is poor, an effective solution is not provided at present.

Fig. 1 is an application scenario diagram of a method for a blockchain cross-chain transaction according to an embodiment of the present invention, and the method embodiment provided in this embodiment may be applied to the scenario shown in fig. 1. As shown in fig. 1, an application scenario of blockchain cross-chain transaction includes a cross-chain transaction architecture 102, a first application chain 104, and a second application chain 106, where the first application chain 104 and the second application chain 106 are blockchains that need cross-chain transaction, that is, cross-chain transaction nodes, only two application chains are shown in the figure, and more application chains may be included in an actual application scenario. According to different application scenarios, the requirements of the cross-chain transaction architecture 102 between the first application chain 104 and the second application chain 106 are different, and a plurality of nodes may be included in each of the cross-chain transaction architecture 102, the first application chain 104, and the second application chain 106.
In some application scenarios, for example, each department in a company has different block chains, and after each data is linked up, how to perform data exchange and service cooperation through the block chains needs to use a cross-chain technique; in this scenario, each application chain inside the company is secure and can trust each other, and only the format of the cross-chain transaction needs to be converted and whether the basic information of the cross-chain transaction is correct or not needs to be verified when the cross-chain transaction is performed.
In other application scenarios, in a federation formed by multiple companies, the companies are required to collaborate business on the blockchains they each maintain. In this case, the blockchain between companies is relatively closed, and the data on the chain of other people is not completely credible, and in this scenario, a relay chain composed of companies is required to endorse the cross-chain transaction of each family together.
In still other application scenarios, in scenarios where there is a unique authority center, the authority center requires management and supervision of the blockchain used by the company of the subordinate organization. In this case, it is not suitable for the subordinate block chains to constitute the relay chain, because there is a logical dependency relationship in this case, and the status is not equal. A unique backbone is required and can be supervised through a blockchain across chains to subordinate agencies. Therefore, a method for providing more flexible cross-chain transaction for cross-chain transaction of application chain is needed.
In an embodiment, fig. 2 is a flowchart of a method for block chain cross-chain transaction according to an embodiment of the present invention, and as shown in fig. 2, a method for cross-chain transaction is provided, which is described by taking an application scenario in fig. 1 as an example, and includes the following steps:
step S210, obtaining an architecture type between the cross-chain transaction nodes participating in the cross-chain transaction, and selecting a cross-chain transaction component corresponding to the architecture type according to the architecture type. The architecture type is an architecture classification for cross-chain transaction according to a common application scenario, and the cross-chain transaction component is a component included in various architecture types, such as a relay chain, a cross-chain gateway, a cross-chain verification engine, and the like. The relay chain can carry out uniform endorsement and verification on cross-chain transactions initiated by each block chain; the cross-chain gateway is used for monitoring cross-chain transactions on a certain block chain and executing forwarding and routing functions; the cross-chain verification engine is a component for verifying on-chain verification information carried by cross-chain transactions out of the block chain. Optionally, the management and maintenance of the architecture type and the corresponding cross-chain trading component are performed through a cross-chain management platform, the cross-chain management platform acquires the architecture type from the client or the platform of the cross-chain management platform, and the cross-chain trading component is configured in advance for each architecture type on the cross-chain management platform. For example, for a high-trust scenario, that is, for a cross-chain transaction between blockchains of different departments in the same company, the cross-chain management platform provides a high-trust architecture, and a preset cross-chain transaction component corresponding to the architecture is a cross-chain gateway, so that the cross-chain management platform selects the cross-chain gateway as a component for constructing the cross-chain transaction architecture.
Step S220, constructing a cross-chain transaction architecture between cross-chain transaction nodes according to the cross-chain transaction component. In step S210, the cross-chain transaction components are determined only according to the architecture type, but specifically in the application scenario, the number of the cross-chain transaction components is selected according to the specific application scenario, parameters are set for the cross-chain transaction components, and finally, a cross-chain transaction architecture is constructed and started. For example, in the high-confidence scenario, in step S210, the cross-chain management platform selects a cross-chain gateway as a component for constructing the cross-chain transaction architecture, and in this step, the cross-chain transaction management platform further needs to select a corresponding number of cross-chain gateways according to the number of application chains in the current scenario, and indicate each application chain to connect to one cross-chain gateway, and connect the cross-chain gateways to each other, and finally construct and start the cross-chain transaction architecture.
In steps S210 to S220, by acquiring the architecture type between transaction nodes participating in the cross-chain transaction, selecting a cross-chain transaction component corresponding to the architecture type according to the architecture type, and constructing and starting a cross-chain transaction architecture according to the cross-chain transaction component, the processing flow of the cross-chain transaction is modularized, the architecture type can be determined according to different scenes, the cross-chain components can be flexibly combined, the complexity of deploying and maintaining a cross-chain system is simplified, and the architecture flexibility and applicability of the cross-chain transaction are improved.
The cross-chain management platform supports a user-defined mode to start the cross-chain system, and the system can automatically judge how to select the cross-chain architecture and start the cross-chain architecture by inputting the description of the scene by the user. In some embodiments, in the automatic recommendation mode, the user is required to provide scenario information through the client, optionally, the cross-chain management slip provides some scenario questions, and the user is required to answer the corresponding scenario questions, for example, performance requirements of the cross-chain transaction, whether an authority center is required in the cross-chain transaction, whether each node performing the cross-chain transaction mutually believes, and the like. The cross-chain management platform can analyze the results of the problems and recommend the corresponding architecture type through an artificial intelligence algorithm. Optionally, a default configuration corresponding to the architecture type and the cross-chain transaction component can be provided while determining the architecture type, and the user can also make configuration modification if the recommended default configuration is not satisfied. The cross-chain architecture automatic selection function provided by the cross-chain management platform can adapt to the cross-chain architecture according to the scene information, and the building efficiency of the cross-chain transaction architecture is further improved.
In some embodiments, in a user-defined mode, a user can specify one of several architectures provided by the cross-chain management platform to launch the cross-chain architecture, and the user also needs to specify configuration information for the corresponding cross-chain trading component. For example, the number of inter-link gateways that need to be started in the current inter-link architecture, the plug-in adapted to which blockchain system each inter-link gateway uses, the number of nodes for starting relay links, and the like. As another example, multiple cross-chain gateways may be selected for an application chain for high availability considerations. The user-defined mode provides a cross-chain architecture mode with higher selectivity for the user, the customization degree of the cross-chain transaction architecture is increased while the construction efficiency of the cross-chain transaction architecture is improved, and the compatibility and the adaptability of the cross-chain transaction architecture are higher.
In one embodiment, where the architecture type is a chain-to-chain mode, a cross-chain gateway is selected as the cross-chain transaction component. The chain-to-chain mode is suitable for a scenario in which the trust between cross-chain transaction nodes is high, fig. 3 is a schematic diagram of the chain-to-chain mode in blockchain cross-chain transaction implemented according to the present invention, as shown in fig. 3, in this scenario, an application chain a and an application chain B are in a relatively trusted and secure environment, and only data that needs to be shared by a part of the application chain a needs to be transmitted to the application chain B, and the data is provided to a service of the application chain B for use. Therefore, the cross-chain trading platform selects a cross-chain gateway as a cross-chain trading component, and constructs a cross-chain trading architecture to use the cross-chain gateway A for the application chain A and the cross-chain gateway B for the application chain B, and the cross-chain gateway converts the format of the trading on each application chain, directly interfaces with the cross-chain gateway of the other chain and interacts according to the uniform cross-chain trading format. Only two application chains are shown in fig. 3, and more application chains and more cross-chain gateways corresponding to the application chains may be included in an actual application scenario. The combined mode is simple enough for both cross-chain parties, the operation and maintenance cost can be reduced, and the routing and transmission efficiency of cross-chain transactions is high.
In one embodiment, where the architecture type is relay chain mode, a relay chain, a cross-chain gateway, and a cross-chain validation engine are selected as cross-chain transaction components. The relay chain mode is suitable for a multi-union scenario with weak trust, fig. 4 is a schematic diagram of the relay chain mode in block chain cross-chain transaction implemented according to the present invention, as shown in fig. 4, in this scenario, a cross-chain transaction platform selects a relay chain, a cross-chain gateway, and a cross-chain verification engine as cross-chain transaction components, and constructs a cross-chain transaction architecture as an application chain a connected to a cross-chain gateway a, an application chain B connected to a cross-chain gateway B, and the cross-chain gateway a and the cross-chain gateway B are indirectly connected through the relay chain components. Due to the weak trust, application chain B cannot fully trust its transactions if just the transactions obtained from the cross-chain gateway of application chain a in chain-to-chain mode. In the relay chain mode, the validity of the cross-chain transaction is guaranteed by the relay chain itself, because each node of the relay chain is responsible for each alliance participating in the cross-chain transaction, and the cross-chain transaction needs to be signed by each node of the relay chain and can be executed through the verification of a cross-chain transaction verification engine (the cross-chain transaction verification engine is not shown in the figure). Fig. 4 shows only two application chains, and in an actual application scenario, more application chains may be included, and the application chains may interact with each other through the same relay chain or through multiple relay chains. In some embodiments, for better expansion, the cross-link trading component further includes a relay link gateway, and the cross-link trading platform further selects the relay link gateway, so that the relay link can further interconnect through the relay link gateway, and the relay link gateway undertakes routing of the cross-relay link.
In one embodiment, where the architecture type is master-slave mode, relay chains and cross-chain gateways are selected as cross-chain transaction components. The master-slave chain mode is suitable for a single authority center scenario, fig. 5 is a schematic diagram of the master-slave chain mode in block chain cross-chain transaction implemented according to the present invention, as shown in fig. 5, in this scenario, a business party represented by an application chain has a logical up-down management relationship. The cross-chain trading platform selects a relay chain and a cross-chain gateway as cross-chain trading components, the relay chain represents a party in an authority center at the moment and is called a main chain, and other application chains are called slave chains. The cross-chain trading platform constructs a cross-chain trading architecture as shown in fig. 5, a main chain in fig. 5 is a relay chain, a slave chain a, a slave chain B and a slave chain C are all application chains, the slave chain a is connected with the cross-chain gateway a, the cross-chain gateway a is connected with the relay chain, the slave chain B is connected with the cross-chain gateway B, the cross-chain gateway B is connected with the relay chain, the slave chain C is connected with the cross-chain gateway C, and the cross-chain gateway C is connected with the relay chain. Only three application chains and one main chain are shown in fig. 5, and more application chains or more main chains may be included in an actual application scenario. The relay chain has corresponding management authority for cross-chain transaction between the slave chains, and even can manage and supervise data and contracts inside the slave chains.
It should be understood that the steps in the above-described flowcharts are shown in order as indicated by the arrows, but the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a portion of the steps in the flowchart may include multiple sub-steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the sub-steps or stages is not necessarily sequential, but may be performed alternately or alternately with other steps or at least a portion of the sub-steps or stages of other steps.
