In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the embodiment of the present invention, each blockchain network may include one or more nodes, for example, the blockchain network 101 includes a node 1011, a node 1012, a node 1013, and a node 1014, and any two nodes of the nodes 1011 to the node 1014 may be communicatively connected, so as to jointly maintain the blockchain system. The nodes in the blockchain network may have multiple functions, such as a routing function, a transaction function, a blockchain function, a consensus function, and the like, for example, the nodes in the blockchain network may transmit information, such as transaction data transmitted from other nodes, to more nodes to implement communication between the nodes; alternatively, nodes in the blockchain network may be used to support a user in conducting transactions; alternatively, nodes in the blockchain network may be used to record all transactions historically; alternatively, a node in the blockchain network may generate a new block in the blockchain network by verifying and recording the transaction. In practical applications, the routing function is a function that each node in the blockchain network must have, and other functions can be set by those skilled in the art according to practical needs.
It should be noted that, a node in the blockchain network may be on a physical machine (server), and a node may specifically refer to a process or a series of processes running in the server. For example, the node 1011 may be a process running on a server, or may refer to a server, which is not limited in particular.
In the embodiment of the present invention, any blockchain network may be deployed with a dedicated chain resource and a cross-chain resource, where the dedicated chain resource is a resource required by the blockchain network to execute internal transactions, and the cross-chain resource is a resource required by the blockchain network to execute external transactions with other blockchain networks. For example, when the blockchain network 101 is a transaction chain network, the blockchain network 102 is a settlement chain network, and the blockchain network 103 is an integration chain network, the interlink network 10 may form an interlink payment network, transaction interlink resources are deployed on the transaction chain network, settlement interlink resources are deployed on the settlement chain network, and integration interlink resources are deployed on the integration chain network, and the transaction chain network may call the settlement interlink resources of the settlement chain network to perform asset settlement when executing a transaction using the transaction interlink resources, and may call the integration chain network to update the integration according to an asset settlement result of the settlement chain network and a transaction type of the transaction chain network.
It should be noted that the above is only an exemplary and simple description, and the number of the block networks and the number of the nodes in the block networks are only for convenience of description and do not constitute a limitation to the scheme, in a specific implementation, the number of the block networks included in the inter-chain network may be greater than 3, for example, 4 or more than 4, and correspondingly, the number of the nodes included in each block network may be greater than 4, for example, 5 or more than 5, and is not limited.
Fig. 2 is a schematic diagram of a possible system architecture provided by an embodiment of the present invention, as shown in fig. 2, the system architecture is provided with a proxy node 130 and at least one inter-link network, such as an inter-link network 10, an inter-link network 11, and an inter-link network 12; the inter-link network 10 includes a blockchain network 101, a blockchain network 102, and a blockchain network 103, the inter-link network 11 includes a blockchain network 111 and a blockchain network 112, and the inter-link network 12 includes a blockchain network 121 and a blockchain network 122, and each blockchain network in each inter-link network may be set according to the method illustrated in fig. 1.
As shown in fig. 2, the system architecture is provided with a user end 140, the user end 140 may be any terminal device arranged at a developer side, such as a laptop, an Ipad, a mobile phone, and the like, and the developer may participate in a development process of a cross-link network through the user end 140.
In the embodiment of the present invention, the proxy node 130 may be connected to the user end 140 and each of the blockchain networks, for example, the connection may be in a limited manner, or may be connected in a wireless manner, which is not limited in particular.
Based on the system architectures illustrated in fig. 1 and fig. 2, fig. 3 is a schematic flowchart of a resource processing method provided in an embodiment of the present invention, where the method is applied to the proxy node 130, and the method includes:
step 301, receiving a resource calling request sent by a user side, where the resource calling request includes an identifier of a resource to be called.
In the embodiment of the present invention, a cross-chain resource is deployed in each blockchain network of a cross-chain network by a developer in a development phase, where the cross-chain resource may refer to any type of resource, for example, may be an intelligent contract deployed on the blockchain network, or may also be data or assets stored in a database of the blockchain network, or may also be data stored in the intelligent contract; the storage form of the data may be a data table, or may also be other types, such as a stack, a graph, and the like, without limitation.
In one example, the identifier of the resource to be called may be composed of an address of the resource to be called, an identifier of a blockchain network deployed by the resource to be called, and an identifier of a cross-chain network in which the blockchain network deployed by the resource to be called is located. For example, if the resource to be invoked is a smart contract of 0X1 deployed on the blockchain network 112, the identity of the resource to be invoked may be "Cross-chain network 11. blockchain network 112.0X 1".
In the embodiment of the present invention, when a developer needs to call a cross-link resource in any cross-link network, an identifier of the resource to be called may be input on a call interface of the user terminal 140, and accordingly, after the user terminal 140 receives the identifier of the resource to be called input by the developer, an Internet Protocol (IP) address of the proxy node 130 and a port number used for a cross-link service in the proxy node 130 may be obtained, and then a resource call request is generated based on the identifier of the resource to be called, the IP address of the proxy node 130, and the port number used for the cross-link service. The IP address of the proxy node 130 and the port number for the cross-link service are obtained by the user end 140 and the proxy node 130 in advance through interaction, and the user end 140 and the proxy node 130 can update in real time through interaction.
In one example, the resource invocation request may be a URL address constructed based on the identification of the resource to be invoked, the IP address of the proxy node 130, and the port number for the cross-chain service, such as if the IP address of the proxy node 130 is IP:127.0.0.1, the port number for the cross-chain service in the proxy node 130 is 8080, and the identification of the resource to be invoked is "cross-chain network 11. blockchain network 112.0X 1", the resource invocation request may be "http:// 127.0.0.1/8080. cross-chain network 11/blockchain network 112/0X 1".
Step 302, determining the block chain network corresponding to the identifier of the resource to be called according to the corresponding relationship between the resource identifier and the block chain network.
In a possible implementation manner, the proxy node 130 may encapsulate management units corresponding to the respective blockchain networks, and the proxy node may be indirectly connected to the respective blockchain networks through the respective management units. For example, as shown in fig. 2, the management unit 1 corresponding to the blockchain network 101, the management unit 2 corresponding to the blockchain network 102, the management unit 3 corresponding to the blockchain network 103, the management unit 4 corresponding to the blockchain network 111, the management unit 5 corresponding to the blockchain network 112, the management unit 6 corresponding to the blockchain network 121, and the management unit 7 corresponding to the blockchain network 122 may be respectively packaged in the proxy node 130, and the proxy node 130 may respectively realize connections with the blockchain network 101 to the blockchain network 103, the blockchain network 111 and the blockchain network 112, the blockchain network 121 and the blockchain network 122 through the management units 1 to 7.
The encapsulation has various meanings, for example, the management unit may be a Software Development Kit (SDK) component deployed inside the proxy node 130, or may be a device independent of the proxy node 130, and the communication with the proxy node 130 is realized through a Remote Procedure Call (RPC) protocol; and, although the management unit is encapsulated in the proxy node 130, the application running on the management unit is independent of the application running on the proxy node 130, the application running on the management unit is used to manage the nodes and resources in the connected blockchain network, and the application running on the proxy node 130 is used to manage the management unit.
In this embodiment of the present invention, the management unit may be communicatively connected to each node in the corresponding blockchain network, for example, by wired connection or wireless connection with each node, or may also deploy an SDK component on each node, and implement communicative connection with each node through the SDK component on each node, which is not limited.
In one example, based on this implementation, a developer may deploy cross-chain resources by:
in step a, the developer sends the configuration information of each cross-chain resource to be deployed to the agent node 130 through the user terminal 140.
The configuration information of each cross-chain resource may include an identifier of a blockchain network that the cross-chain resource needs to be deployed, an identifier of a cross-chain network where the blockchain network that needs to be deployed is located, and a cross-chain resource, where types of the cross-chain resource are different, and the cross-chain resource is also different, for example, if the cross-chain resource is an intelligent contract, the cross-chain resource may include implementation logic (or implementation logic and initial data) of the intelligent contract, and if the cross-chain resource is an asset, data of the cross-chain resource may include an asset type of each account and a value corresponding to the asset type.
In a specific implementation, the proxy node 130 may open a registration interface to each user side in advance, and if the user side 140 has a registration authority, the user side 140 may input configuration information of the cross-link resource in the registration interface of the proxy node 130, so as to send the configuration information of the cross-link resource to the proxy node 130.
Step b, the agent node 130 determines the management unit corresponding to each cross-chain resource to be deployed according to the configuration information of each cross-chain resource to be deployed, and distributes each cross-chain resource to be deployed to the corresponding management unit.
In a specific implementation, for any cross-chain resource to be deployed, the agent node 130 may determine the management unit corresponding to the cross-chain resource according to the identifier of the block chain network to be deployed of the cross-chain resource and the cross-chain network in which the block chain network to be deployed is located, and then distribute the data of the cross-chain resource to the corresponding management unit. For example, as shown in fig. 2, if a certain cross-link resource is an intelligent contract, and the blockchain network to be deployed by the intelligent contract is the blockchain network 112 in the cross-link system 11, since the management unit 5 is used to manage each node in the blockchain network 112, the blockchain network corresponding to the intelligent contract is the management unit 5, and the agent node 130 may send the intelligent contract to the management unit 5.
And c, after receiving the cross-chain resources to be deployed, the management unit deploys the cross-chain resources in the block chain network managed by the management unit.
For example, if the management unit 5 receives the smart contract sent by the proxy node 130, the management unit 5 may send the smart contract to any node (or all nodes) in the blockchain network 112 through the SDK component deployed on the node, so that each node in the blockchain network 112 deploys the execution contract into the blockchain network 112; if the deployment is successful, any node may send the address of the intelligent contract deployed in the blockchain network 112 to the management unit 5, if the deployment fails, each node may retry for multiple times, and if the deployment still fails after retrying for a preset number of times, a response message of the failure in deployment may be sent to the management unit 5.
In step d, the management unit sends the deployment result of each cross-chain resource to be deployed to the agent node 130.
When the deployment is successful, if the cross-link resource is an intelligent contract, the deployment result of the cross-link resource may be an address of the intelligent contract in the blockchain network, if the cross-link resource is data in the data table, the deployment result of the cross-link resource may be a table name of the data table, and if the cross-link resource is an asset, the deployment result of the cross-link resource may be an asset account name.
Step e, the agent node 130 sends the deployment result of each management unit to the user terminal 140.
In an example, the agent node 130 may further generate a correspondence between the cross-chain resource and the blockchain network according to a deployment result of each management unit, where the correspondence between the cross-chain resource and the blockchain network is used to indicate a correspondence between each deployed cross-chain resource and the belonged blockchain network, and the correspondence may be stored in a form of a table, or may also be stored in a form of a graph, which is not limited.
For example, taking the system architecture illustrated in fig. 2 as an example, table 1 is a schematic table of a correspondence relationship between cross-chain resources and a blockchain network according to an embodiment of the present invention.

As shown in table 1, the correspondence relationship between the cross-link resource and the blockchain network may include a resource deployment situation on each cross-link network managed by the agent node 130, and the resource deployment situation on each cross-link network may include a cross-link resource deployed on each blockchain network in the cross-link network and a management unit corresponding to each blockchain network, for example, the cross-link network 11 includes a blockchain network 111 and a blockchain network 112, the blockchain network 111 corresponds to the management unit 4, the blockchain network 111 has an intelligent contract 0X3 and a data table 2, the blockchain network 112 corresponds to the management unit 5, and the blockchain network 112 has a data table 3.
In the embodiment of the invention, the corresponding relation between the cross-chain resources and the block chain network is set according to the hierarchical form of the cross-chain resources deployed in each cross-chain network, the block chain network in each cross-chain network and the block chain network managed by the proxy node, so that the proxy node can flexibly manage the cross-chain resources in each cross-chain network, and the proxy node can quickly determine the block chain network corresponding to the cross-chain resources based on the corresponding relation, thereby improving the efficiency of cross-chain resource calling.
In a specific implementation, after receiving the resource calling request, the proxy node 130 may first obtain the identifier of the resource to be called by parsing from the resource calling request, and then query the correspondence between the resource identifier and the blockchain network according to the identifier of the resource to be called, to determine the blockchain network corresponding to the identifier of the resource to be called.
Step 303, calling the resource to be called from the block chain system corresponding to the resource to be called to obtain a calling result.
In the embodiment of the present invention, the proxy node 130 may also be directly connected to each node in each managed inter-link network, so that, after determining the blockchain network corresponding to the identifier of the resource to be called, the proxy node 130 may directly send the call request corresponding to the resource to be called to any node of the blockchain network, so that each node in the blockchain network calls the resource to be called to perform a call operation. However, in this way, the proxy node 130 not only needs to manage the cross-link resources of each cross-link network, but also needs to perform a call operation of the cross-link resources, so that the pressure of the proxy node 130 is large, and the performance loss is severe.
To solve the above problem, in one possible implementation, the proxy node 130 is indirectly connected to nodes in each of the inter-chain networks through each management unit, each managing one of the blockchain networks, and thus, after the identifier of the resource to be called is obtained by parsing from the call request, the proxy node 130 may first obtain each blockchain network in the cross-chain network and the management unit corresponding to each blockchain network according to the identifier lookup table 1 of the cross-chain network in the identifier of the resource to be called, further, according to the identifier of the blockchain network in the identifier of the resource to be called, the management unit corresponding to the blockchain network in the identifier of the resource to be called is determined and is used as the management unit corresponding to the resource to be called, and then sending the calling request of the resource to be called to a management unit corresponding to the resource to be called.
For example, if the resource invocation request is "http:// 127.0.0.1/8080. inter-link network 11/blockchain network 111/0X 3", the proxy node 130 may restore the identifier of the resource to be invoked "inter-link network 11. blockchain network 111.0X 3" from "http:// 127.0.1/8080. inter-link network 11/blockchain network 111/0X 3", and then pull all the management units under the inter-link network 11, i.e., the management unit 4 and the management unit 5, from table 1 according to the identifier of the inter-link network in the identifier of the resource to be invoked "inter-link network 11", where the management unit 4 is used for managing the blockchain network 111 and the management unit 5 is used for managing the blockchain network 112; further, the agent node 130 may determine the management unit of the management blockchain network 111, that is, the management unit 4, from all the management units under the cross-chain network 11 according to the identifier "blockchain network 111" of the blockchain network in the identifier of the resource to be called, and thus, the agent node 130 may generate a call instruction according to the identifier of the cross-chain resource intelligent contract 0X3 to be called, and send the call instruction to the management unit 4.
In the implementation manner, management work of the cross-chain resources is placed at the proxy node for execution, and call work of the cross-chain resources in each blockchain network is placed at the management unit corresponding to each blockchain network for execution, so that on one hand, management and call of the cross-chain resources can be decoupled, flexibility of resource processing is improved, and on the other hand, pressure and performance loss of the proxy node can be reduced.
In an example, the resource invocation request may further include an invocation interface, the invocation interface may be one or more of various common interfaces of the cross-chain resource, and after determining the management unit corresponding to the cross-chain resource to be invoked, the proxy node 130 may further generate an invocation instruction according to the identifier of the cross-chain resource to be invoked and the invocation interface, and send the invocation instruction to the corresponding management unit.
The common interfaces of the various cross-chain resources are set based on resource access requirements of the various cross-chain resources, and may be set by a person skilled in the art according to experience, which is not limited specifically.
In the embodiment of the present invention, the cross-chain resource may have the following general interfaces:
a getData () interface for obtaining data or assets in a data table or database deployed in the blockchain network;
a setData () interface for updating data or assets in a data table or database deployed in the blockchain network, the updating operation being addition, deletion or modification;
a call () interface for calling logic of an intelligent contract deployed in a blockchain network to obtain data in the intelligent contract;
a sendtransmission () interface for invoking logic of an intelligent contract deployed in a blockchain network to operate on data in the intelligent contract;
the system comprises a register EventHandler () interface, a block chain network and a block chain network, wherein the register EventHandler () interface is used for registering a buried point event on the block chain network, and when the buried point event on the block chain network is triggered, the register EventHandler () interface can actively push the triggered information of the buried point event to a set address.
The call () interface is only used for acquiring data in the intelligent contract and not executing transaction, so that the data in the intelligent contract can not be updated, and correspondingly, the data in the block chain network can not be updated; while the sendtransmission () interface is used to perform operations using the data in the intelligent contract, it will update the data in the intelligent contract and correspondingly also in the blockchain network.
In the embodiment of the present invention, the getData () interface and setData () interface are generally used for operating on a data table, and the call () interface and sendtransmission () interface are generally used for operating on an intelligent contract.
For ease of understanding, for example, if the cross-link resource is smart contract 0X3 (i.e., the address of the cross-link resource identified as a smart contract 0X03), then after the smart contract 0X3 is deployed to the blockchain network 111, the blockchain network 111 will store the above-mentioned 5 call interfaces of the smart contract 0X3 and the contract data of the smart contract 0X3 at the address of the smart contract 0X 3; thus, if the management unit 4 receives a call instruction of "smart contract 0X3, call () interface", the management unit 4 may first create a contract object of the smart contract 0X3 based on the address of the smart contract 0X3, and then call the call () interface of the contract object of the smart contract 0X3 to obtain contract data in the smart contract 0X3, that is, contract data stored at the address of the smart contract 0X3, and obtain a call result.
For another example, if the inter-link resource is a data Table (that is, the identifier of the inter-link resource is a Table name Table of the data Table), after the data Table is deployed to the blockchain network, the blockchain network stores the 5 call interfaces of the data Table and data of the data Table at the address of the data Table; thus, if the management unit receives a call instruction of the "data Table, setData () interface", the management unit may open the data Table according to the Table name of the data Table, create a contract object of the first contract in the opening process, then call the setData () interface of the contract object of the first contract to update the data in the data Table, and obtain a call result. The first contract is a contract which is pre-deployed in the blockchain network, and the first contract is used for operating data in the data table.
It should be noted that the above is only an exemplary description, and does not constitute a limitation on the present solution; it can be understood that the call operation in the embodiment of the present invention may be a call operation in a single blockchain network, or may also be an interactive call operation in multiple blockchain networks, which is not limited.
In the embodiment of the invention, the same calling interface is set for various calling resources, so that a user can call the calling resources based on the same input mode without adapting to each calling resource, thereby reducing the development complexity and improving the development efficiency.
In one example, the management unit may also be provided with the following interfaces:
getResource () interface for acquiring all resources managed by the management unit;
and the getBlockHeader () interface is used for acquiring the block header information of the block chain network managed by the management unit.
In a specific implementation, after receiving the call instruction, the management unit may first use a getResource () interface to pull all resources managed by the management unit, and determine whether all managed resources include a resource to be called in the call instruction, if not, may send a response message indicating that the call is failed to the proxy node 130, and if so, may execute the call operation.
In the above example, by determining whether the resource to be called belongs to the cross-chain resource managed by the management unit before the call operation is executed, the management unit can accurately call the cross-chain resource managed by the management unit, avoid unnecessary call operation, and improve the call efficiency.
In the embodiment of the present invention, after receiving the call result sent by the blockchain network, the management unit may also send the call result of the resource to be called back to the user terminal 140 via the proxy node 130, so that after obtaining the call result through the user terminal 140, a developer may execute subsequent operations according to the call result, such as determining whether each cross-chain resource deployed on the cross-chain network is accurate, whether a service is performed on the cross-chain network, and the like.
In the above embodiment of the present invention, after receiving a resource calling request sent by a user, a proxy node determines, according to a correspondence between an identifier of a cross-link resource and a block chain network, a block chain network corresponding to the identifier of a resource to be called, and calls the resource to be called from the block chain network corresponding to the resource to be called, to obtain a calling result; and the resource calling request comprises the identifier of the resource to be called. In the embodiment of the invention, the proxy node is arranged to manage the cross-chain resources in the cross-chain network, so that the client can call the cross-chain resources in the cross-chain network by directly sending the resource calling request to the proxy node, and the method can call different resources of different block chain networks by adopting the same calling mode without one-to-one adaptation of each block chain network, thereby having better flexibility and higher user experience.
