Detailed Description

The core of the invention is to provide a cross-link data access device and a system supporting supervision, under the establishment of a first cross-link gateway, even if each alliance link is based on different bottom layer technical platforms, the data access between the alliance links can be realized; and under the establishment of the second cross-link gateway, the cooperation with the first cross-link gateway can realize that each monitoring system accesses and monitors the data of each alliance chain, and finds the risks existing in the alliance chain in time, thereby being beneficial to the healthy development of the alliance chain.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a monitoring-supported cross-link data access apparatus according to an embodiment of the present invention.

The supervision-supporting cross-chain data access device comprises:

a first inter-link gateway 100 connected to each of the federation links one by one; each first inter-link gateway 100 is accessed to the same inter-link gateway bus, and is configured to convert an interface protocol of a connected alliance link and a universal inter-link communication protocol corresponding to the inter-link gateway bus to each other, so as to implement data access between the alliance links;

a second cross-link gateway 200 connected to each monitoring system one by one; each second inter-link gateway 200 is connected to the inter-link gateway bus, and is configured to convert an interface protocol of a connected monitoring system and a universal inter-link communication protocol to each other, so as to enable each monitoring system to access and monitor data of each alliance link by means of the first inter-link gateway 100.

Specifically, the cross-link data access device of the present application includes a first cross-link gateway 100 and a second cross-link gateway 200, and the working principle thereof is as follows:

the first cross-link gateway 100 is connected to federation chains (specifically, service federation chains, which are instantiations of block chains in different application scenarios) in the system one by one (as shown in fig. 1, the first cross-link gateway a is connected to the federation chain a, the first cross-link gateway B is connected to the federation chain B … …, and the first cross-link gateway N is connected to the federation chain N), that is, the first cross-link gateway 100 is the same as the number of federation chains in the system; the second inter-link gateways 200 are connected to the monitoring systems one by one (as shown in fig. 1, the second inter-link gateway 1 is connected to the monitoring system 1, the second inter-link gateway 2 is connected … … to the monitoring system 2, and the second inter-link gateway M is connected to the monitoring system M), that is, the number of the second inter-link gateways 200 is the same as that of the monitoring systems. Each of the first inter-link gateway 100 and the second inter-link gateway 200 is connected to the same inter-link gateway bus, that is, a general inter-link communication protocol is adopted between the inter-link gateways, so that the expansibility is good and the networking is convenient.

Take data transmission between federation chain a and federation chain B as an example: federation chain A sends a first cross-chain access request to a first cross-chain gateway A. The first cross-link gateway A is used for receiving a first cross-link access request which is transmitted by the alliance link A and is pre-sent to the alliance link B, converting the first cross-link access request into a first general cross-link access request supporting a general inter-link communication protocol corresponding to a cross-link gateway bus, and transmitting the first general cross-link access request to the first cross-link gateway B through the cross-link gateway bus. The first cross-link gateway B is configured to receive a first generic cross-link access request transmitted through a cross-link gateway bus, convert the first generic cross-link access request into a second cross-link access request supporting an interface protocol of the federation chain B (the second generic cross-link access request is the same as the first cross-link access request in terms of the actual request content, but different from the supported protocol), and transmit the second cross-link access request to the federation chain B. And the federation chain B returns the first data to the first cross-chain gateway B according to the second cross-chain access request. The first cross-link gateway B is used for receiving first data which are transmitted by the alliance link B and are pre-sent to the alliance link A, converting the first data into first general data supporting a general inter-link communication protocol, and transmitting the first general data to the first cross-link gateway A through a cross-link gateway bus. The first inter-link gateway a is configured to receive first general data transmitted through an inter-link gateway bus, convert the first general data into second data (the same as the actual data content corresponding to the first data, but different from the supported protocol) supporting an interface protocol of the federation link a, and transmit the second data to the federation link a, so as to enable the federation link a to access data from the federation link B (the same applies to federation link B to access data from the federation link a, and details of the application are not described herein). As can be seen, under the establishment of the first cross-link gateway 100, even if the federation chain a and the federation chain B are based on different underlying technology platforms, data access between the federation chain a and the federation chain B can be realized, and the problems of difficult intercommunication, difficult mutual recognition, difficult mutual trust and difficult mutual access of cross-link data access are solved.

Take the example that the supervisory system 1 accesses and supervises the data of the federation chain a: the second inter-link gateway 1 is configured to receive a first data access request which is transmitted by the monitoring system 1 and is pre-sent to the alliance link a, convert the first data access request into a first general data access request supporting a general inter-link communication protocol, and transmit the first general data access request to the first inter-link gateway a via the inter-link gateway bus. The first cross-link gateway A is used for receiving a first general data access request transmitted from a cross-link gateway bus, converting the first general data access request into a second data access request supporting an interface protocol of the federation link A (the content of a substantial request corresponding to the first data access request is the same, and only the supported protocol is different), and transmitting the second data access request to the federation link A. And the federation chain A returns the third data to the first cross-chain gateway A according to the second data access request. The first cross-link gateway a is configured to receive third data that is transmitted by the alliance link a and is pre-sent to the monitoring system 1, convert the third data into third general data that supports a universal inter-link communication protocol, and transmit the third general data to the second cross-link gateway 1 through the cross-link gateway bus. The second inter-link gateway 1 is configured to receive third general data transmitted by the inter-link gateway bus, convert the third general data into fourth data (the same as the actual data content corresponding to the third data, and only different protocols are supported) supporting an interface protocol of the monitoring system 1, and transmit the fourth data to the monitoring system 1, so that the monitoring system 1 can access and monitor the data of the federation chain a, thereby timely discovering risks (e.g., illegal risks) existing in the federation chain, and facilitating the healthy development of the federation chain.

The invention provides a cross-link data access device supporting supervision, which comprises first cross-link gateways and second cross-link gateways, wherein the first cross-link gateways are connected with all alliance links one by one, and the second cross-link gateways are connected with all supervision systems one by one. And each first cross-link gateway and each second cross-link gateway are connected to the same cross-link gateway bus. The first inter-link gateway is used for converting an interface protocol of the connected alliance link and a universal inter-link communication protocol corresponding to a cross-link gateway bus to each other so as to realize data access among all the alliance links; the second cross-link gateway is used for converting the interface protocol of the connected monitoring systems and the communication protocol between the universal links into each other so as to realize that each monitoring system accesses and monitors the data of each alliance link by means of the first cross-link gateway. Therefore, under the establishment of the first cross-link gateway, even if all the alliance links are based on different bottom-layer technical platforms, data access among all the alliance links can be achieved; and under the establishment of the second cross-link gateway, the cooperation with the first cross-link gateway can realize that each monitoring system accesses and monitors the data of each alliance chain, and finds the risks existing in the alliance chain in time, thereby being beneficial to the healthy development of the alliance chain.

Specifically, for the first cross-link gateway 100, the federation link resource routing synchronization module 1033, via the first communication module 101 and the second communication module 102, synchronizes resource routing address information of all federation links in the system into three cases: 1) in the process of power-on initialization of the first cross-link gateway 100, the alliance-link resource routing synchronization module 1033 traverses all resources of the connected alliance link by using the first communication module 101, so as to store all resource routing address information corresponding to the connected alliance link in the cross-link resource database, and notifies other cross-link gateways in the network by using the second communication module 102 to read the resource routing address information, so that the resource routing address information of all alliance links is stored in the cross-link resource database of all cross-link gateways in the network, that is, the resource routing address information of all alliance links in the synchronization system is realized. 2) In the working process of the first inter-link gateway 100, the federation link resource routing synchronization module 1033 periodically notifies other inter-link gateways in the network to read the resource routing address information by means of the second communication module 102, that is, the resource routing address information of all federation links in the periodic synchronization system is realized. 3) When a new resource is deployed in a federation chain, the federation chain notifies a first cross-link gateway 100 connected to the federation chain, the first cross-link gateway 100 updates and stores resource routing address information of the newly deployed resource into a cross-link resource database, and notifies other cross-link gateways in the network to read the resource routing address information and synchronize resource routing address information of all federation chains in the system by means of the second communication module 102.

The protocol conversion module 1034 is connected to the first communication module 101, the second communication module 102, and the federation chain resource database management module 1032, respectively. For the first cross-link gateway 100: the protocol conversion module 1034 is configured to receive a protocol selection instruction, determine, based on the received protocol selection instruction, an interface protocol (referred to as a third interface protocol) of a federation chain connected to the inter-chain gateway where the protocol conversion module is located, perform mutual conversion between the third interface protocol and a universal chain communication protocol, query resource routing address information of any federation chain by using the federation chain resource database management module 1032, and implement data access between federation chains by using the first communication module 101 and the second communication module 102 based on the queried resource routing address information. For the second cross-link gateway 200: the protocol conversion module 1034 is configured to receive the protocol selection instruction, determine, based on the received protocol selection instruction, an interface protocol (referred to as a fourth interface protocol) of the monitoring system connected to the inter-link gateway where the monitoring system is located, perform mutual conversion between the fourth interface protocol and the universal link communication protocol, query resource routing address information of any one of the federation links by using the federation link resource database management module 1032, and implement, based on the queried resource routing address information, access and monitoring of data of each federation link by each monitoring system by using the first communication module 101 and the second communication module 102.

It should be noted that the principle of setting the resource routing address information is as follows: resources on different alliance chains are various and comprise intelligent contracts, assets, channels, data tables and the like, the resources on a single alliance chain can be located and accessed through contract addresses or names, and a higher-level resource locating protocol is needed among different alliance chains and between the alliance chains and a supervision system. In order to enable a user to access resources of the alliance chain without being concerned about which region, mechanism or machine room the resources are located in and the specific implementation of the alliance chain, the resource location and access can be realized only by providing resource routing address information (resource addresses and related parameters). The application adopts a uniform resource addressing protocol to intelligently locate the required resources.

More specifically, the storage module 1031 of the present application may include a memory and a hard disk, where the memory may temporarily store the cross-chain resource database, and the hard disk may permanently store the cross-chain resource database.

the alliance chain protocol adaptation modules 1042 are in one-to-one correspondence with the interface protocols of the alliance chains supported by the cross-chain gateway, that is, the number of the alliance chain protocol adaptation modules 1042 is equal to the number of the alliance chains supported by the cross-chain gateway. Taking the first interface protocol as an example, the alliance link protocol adapting module 1042 corresponding to the first interface protocol is configured to convert the first interface protocol and the universal inter-link communication protocol into each other.

The monitoring system protocol adaptation modules 1043 correspond to the interface protocols of the monitoring systems supported by the inter-link gateway one to one, that is, the number of the monitoring system protocol adaptation modules 1043 is equal to the number of the monitoring systems supported by the inter-link gateway. Taking the second interface protocol as an example, the monitoring system protocol adaptation module 1043 corresponding to the second interface protocol is configured to convert the second interface protocol and the universal inter-link communication protocol into each other.

Based on this, for the first cross-link gateway 100: the protocol selection module 1041 determines, based on the received protocol selection instruction, an interface protocol of the alliance chain connected to the inter-chain gateway where the protocol selection module is located. The protocol conversion initiating module 1044 is configured to initiate the corresponding alliance link protocol adapting module 1042 to enter a protocol conversion task according to the interface protocol determined by the protocol selecting module 1041, and if the protocol selecting module 1041 determines that the interface protocol of the alliance link connected to the inter-link gateway where the protocol selecting module itself is located is the first interface protocol, the protocol conversion initiating module 1044 initiates the alliance link protocol adapting module 1042 for mutually converting the first interface protocol and the universal inter-link communication protocol, so that the alliance link protocol adapting module 1042 enters a protocol conversion task, and adapts to the connected alliance link. For the second cross-link gateway 200: the protocol selection module 1041 determines, based on the received protocol selection instruction, an interface protocol of the monitoring system connected to the inter-link gateway where the protocol selection module is located. The protocol conversion starting module 1044 is configured to start the corresponding monitoring system protocol adaptation module 1043 to enter a protocol conversion operation according to the interface protocol determined by the protocol selection module 1041, and if the protocol selection module 1041 determines that the interface protocol of the monitoring system connected to the inter-link gateway where the protocol selection module is located is the second interface protocol, the protocol conversion starting module 1044 starts the monitoring system protocol adaptation module 1043 which is configured to convert the second interface protocol and the universal inter-link communication protocol to each other, so that the monitoring system protocol adaptation module 1043 enters a protocol conversion operation, thereby adapting to the connected monitoring system.

As can be seen, the first cross-link gateway 100 can be adapted to different alliance links, and the second cross-link gateway 200 can be adapted to different supervisory systems, so that the communication performance is better.

Referring to fig. 4, fig. 4 is a flowchart illustrating a data access procedure between federation chains according to an embodiment of the present invention.

Different service alliance chains need to access each other and get through the intercommunication between service scenes. Thus, business federation chains rely on cross-chain solutions to connect trust islands. The data access process between the alliance chains designed by the application is shown in fig. 4, and a user invokes a cross-chain access intelligent contract of the alliance chain A through a client to initiate a transaction; the first cross-link gateway A inquires the resource routing address information of the alliance link B so as to convert the request data into a universal inter-link communication protocol and send the universal inter-link communication protocol to the first cross-link gateway B; after the first cross-link gateway B verifies the user identity and the authority information, initiating transaction uplink, receiving a transaction receipt, acquiring the Mercker certification of the transaction and the receipt, and finally sending the transaction receipt, the Mercker certification of the transaction and the receipt to the first cross-link gateway A through a universal inter-link communication protocol; the first cross-link gateway A verifies the Merck proof of the transaction and receipt, then returns the transaction receipt to the alliance link A, and finally returns the transaction receipt to the user through the client.

Referring to fig. 5, fig. 5 is a flowchart illustrating a data access between a monitoring system and a federation chain according to an embodiment of the present invention.

In order to ensure the healthy development of the alliance chain industry, organizations such as government departments, industry associations and the like need to supervise the business alliance chain. The data access process between the monitoring system and the alliance chain designed by the application is shown in fig. 5, a user calls a data access interface of the monitoring system 1 through a client to initiate a transaction, and the monitoring system 1 initiates a transaction request to the second inter-chain gateway 1; the second cross-link gateway 1 inquires the resource routing address information of the alliance link A so as to convert the data into a general inter-link communication protocol and send the general inter-link communication protocol to the first cross-link gateway A; after the first cross-link gateway A checks the user identity and the authority information, the first cross-link gateway A initiates a transaction uplink, receives a transaction receipt, acquires the Mercker certification of the transaction and the receipt, and finally sends the transaction receipt, the Mercker certification of the transaction and the receipt to the second cross-link gateway 1 through a universal inter-link communication protocol; the second cross-link gateway 1 verifies the merck proof of the transaction and receipt, then returns the transaction receipt to the supervisory system 1, and finally returns to the user through the client.
