Detailed Description
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.
Fig. 2 exemplarily shows a system architecture to which the method for providing inter-chain communication based on a blockchain according to the embodiment of the present invention is applicable, where the system architecture may be a service chain including a committee chain, a plurality of service systems, and each service system. The committee link is a block link system consisting of nodes, and comprises nodes corresponding to all the service systems; the subject of each service system is recorded in the intelligent contract of the committee chain, wherein the subject can be understood as a message channel in a block chain node and is used for receiving a message corresponding to the subject; each business system is used for subscribing the theme of the business system, namely each business system monitors the information in the theme of each business system in the intelligent contract of the committee chain; and the service chain corresponding to the service system is used for processing the order information sent by the service system.
When each business system performs cross-link communication, a first order can be generated according to the business chain of the business system and written into the corresponding business system theme through the proxy service of the business system, a second order of the business system can be obtained by monitoring the business system theme through the proxy service of the business system, and the business system can send the second order to the corresponding business chain so that the business chain processes the second order.
As shown in fig. 2, the service system includes a service system a, a service system B, and a service system C, and the corresponding service chains are respectively: the service chain a, the service chain b and the service chain c correspond to committee chain nodes which are respectively as follows: the node 1, the node 2 and the node 3 respectively have the following corresponding themes: theme 1, theme 2, theme 3. Further, the committee chain comprises a node 1, a node 2 and a node 3, and each node in the committee chain is deployed with an intelligent contract which comprises a theme 1, a theme 2 and a theme 3. If the business system A needs to send a message to the business system B, the business system C can write the message into the topic 2 of the node 1 through the proxy service of the business system A, and each node in the committee chain executes broadcast consensus, namely the message exists in the topic 2 of the node 2, so that the business system B can subscribe the message in the topic 2 through the proxy service of the business system B. In addition, the service system may subscribe to the theme corresponding to itself, and may also correspond to the theme corresponding to another service system, for example, the service system B may subscribe to the theme 2 and the theme 3 at the same time.
In the embodiment of the invention, the publishing and subscribing of each business system can be realized by adopting the message middleware, and the business system can start an agent service to create a theme in a committee chain through the message middleware and is used for receiving the message corresponding to the theme. Further, the business system can also publish messages to corresponding topics through the proxy service.
Through the system architecture, cross-link communication among the service systems does not need to carry out a large amount of code configuration, and only the message needs to be sent to the theme of the service system to be communicated.
Based on the above description, fig. 3 exemplarily illustrates a flow of a method for block chain based inter-link communication according to an embodiment of the present invention, where the flow may be performed by an apparatus for block chain based inter-link communication.
As shown in fig. 3, the process specifically includes:
step 301, the first service system generates a first order according to the information acquired from the first service chain.
The first business chain is a business chain corresponding to the first business system, and an intelligent contract is deployed in the first business chain and used for storing commodity information in the first business system, wherein the commodity information can be card and coupon information. The first service system may determine information of goods to be purchased from an intelligent contract of the first service chain through an SDK (Software Development Kit), and generate a first order according to the information of the goods to be purchased.
Step 302, the first business system determines a theme of a second business system corresponding to the first order through the committee chain.
The committee chain can store the contrast relationship between each commodity and the subject of each business system in the block chain account book, if each business system sends the respective commodity information to the committee chain, the committee chain is stored in the form of the account book, and when a first business system needs to send a first order, the whole account book can be traversed to check the subject of a second business system corresponding to the first order.
Committee chains can also be used for deploying commodity contracts, and contrast relations between commodities and themes of business systems are recorded in the commodity contracts. For example, the commodity contract records an identifier of a certain commodity, the commodity is a commodity in the business system a, and the subject of the business system a in the committee chain is the subject 1, and then the commodity contract records the corresponding relationship between the identifier of the commodity and the subject 1. In the embodiment of the present invention, a first order generated by a first business system includes commodity information and order information, the commodity information may include commodity category, commodity quoted price, card and ticket denomination, the order information may include order placement price, purchase quantity, supplier, purchaser, and the like, the first business system may record the commodity information in an inquiry request and send the inquiry request to a committee chain, and after receiving the inquiry request, the committee chain determines a corresponding theme of a second business system from a commodity contract according to the commodity information in the inquiry request, and returns the theme of the second business system to the first business system.
Step 303, the first business system writes the first order into the theme of the second business system through the first proxy service of the first business system.
The first business system can package the first order according to a preset format and write the first order into a theme of a second business system of the committee chain through a first agency service of the first business system. Here, the first proxy service may return the first response, that is, the first proxy service writes the first order in the subject of the second business system of the committee chain, and then returns the first response to the first business system. In the embodiment of the invention, the publisher published message and the subscriber subscribed message are decoupled in an asynchronous mode, namely, the first business system sends the first order and the second business system obtains the first order, the first business system does not need to wait until the second business system obtains the response information of the first order, the efficiency of publishing the order by the first business system is improved, and each business system only needs to maintain the theme in the corresponding business chain and the committee chain, so that the maintenance workload of the business systems is reduced.
Specifically, a node corresponding to a first service system in the committee chain is denoted as a first node, and a node corresponding to a second service system in the committee chain is denoted as a second node. The first business system may write the first order into an intelligent contract of the first node through a first proxy service corresponding to the first business system, specifically, into a topic of a second business system of the intelligent contract of the first node, the first node synchronizes the first order written into the intelligent contract to each node of the committee chain, the intelligent contract of the second node is synchronized to the first order, specifically, the first order is synchronized into a topic of the second business system of the intelligent contract of the second node.
The second service system monitors the theme of the second service system through the second proxy service of the second service system, and equivalently, when the theme of the second service system in the intelligent contract of the second node is synchronized to the first order, the second service system can monitor the first order through the second proxy service, so that the first order can be executed through the service chain of the second service system.
In addition, the first business system can write the first order into the theme of the second business system through the first proxy service, and can also monitor the second order written into the theme of the first business system through the first proxy service, wherein the second order is a message which is generated by the third business system and written into the theme of the first business system through the third proxy service of the third business system. The first business system sends the monitored second order to the first business chain, the second order can be executed through the first business chain, after the first business chain finishes executing the second order, the execution result of the second order can be returned to the first business system, and the first business system writes the execution result of the second order into the theme of the third business system through the first agent service. And the third service system monitors the theme and acquires the third order.
For better explaining the embodiment of the present invention, the following describes the process of inter-link communication based on block chains in a specific implementation scenario, as shown in fig. 4, the service system includes a service system a and a service system B, and the corresponding service chains are respectively: the service chain a and the service chain b correspond to committee link nodes which are respectively as follows: the corresponding topics of the node 1 and the node 2 are respectively as follows: theme 1, theme 2. Further, the committee chain comprises a node 1 and a node 2, and each node in the committee chain deploys an intelligent contract which comprises a theme 1 and a theme 2. The message middleware starts a first proxy service for publishing the messages of the business system A and subscribing the messages in the topic 1; the message middleware initiates a second proxy service for publishing messages for business system B and subscribing to messages in topic 2. The business system A needs to send a first order to the business system B for the rights and interests exchange business.
The execution steps are as follows:
step 401, the service system a searches for product and order data that need to be sent to the service system B from the intelligent contract of the service chain a through the SDK, and generates a first order according to the obtained product and order data, for example, the first order has a commodity identifier and a purchase price of a first commodity to be purchased in advance.
Step 402, the service system a determines the subject 2 of the service system B corresponding to the commodity identification of the first commodity from the commodity contract of the node 1 of the committee link through the SDK.
Step 403, the service system a packages the first order according to a preset message format, and sends the first order to the subject 2 of the intelligent contract of the node 1 through the first agent service, and the first agent service returns a response of successful issuing to the service system a.
In step 404, the first order in the subject 2 of the intelligent contract of the node 1 in the committee chain is synchronized to the subject 2 of the intelligent contract of the node 2, namely, the first order is recorded in the subject 2 of the intelligent contract of the node 2.
Step 405, the business system B monitors a first order in the subject 2 of the intelligent contract of the node 2 through the second agent service, analyzes the first order, and determines whether the purchase price in the first order passes a preset exchange rule of the business system B, if it is determined that the purchase price of the first commodity is greater than the cost price, or sends information in the first order to a worker of the business system B, and the worker performs manual determination.
Step 406, if the business system B determines that the first order passes through the preset exchange rule, executing the exchange business in the business chain B, and writing the exchange business completion result into the theme 1 of the intelligent contract of the node 2 through the second proxy service; if the business system B determines that the first order fails the preset exchange rule, a corresponding response, such as the pre-sold price of the first commodity, may be generated and written into the subject 1 of the intelligent contract of the node 2 through the second agent service.
In the technical scheme, the first service system generates the first order, determines the theme of the second service system corresponding to the first order from the committee chain, and writes the first order into the theme of the second service system through the first proxy service, the first service system does not need to store the theme of each service system or configure related information communicated with a third-party service chain in the first service system, the first service system only needs to maintain the service chain of the first service system and the relation between the first service system and the committee chain, and operation and maintenance work of the first service system is reduced. Furthermore, the coupling between each service system and a third-party service chain is removed, the threshold for accessing a new service system is reduced, when a service system and a service chain are added, the newly added service system configures the relevant information between the service chain and the committee chain, the information between the newly added service system and other existing service chains is not required to be configured, and the relationship between the other existing service systems and the newly added service chain is not required to be configured, so that the configuration work of the newly added service system and the service chain is reduced. The expandability of each service system is enhanced, the cross-link access to the third-party service link data can be realized at low cost, and the expandability of the system is enhanced. Through the message middleware, a topic-based publish-subscribe mode is used, and because the implementation is based on a block chain, messages are never lost and cannot be tampered, a transmission channel is encrypted, and connection needs certificate authentication, and communication among all business systems is realized by selecting the cross-organization message middleware and establishing a committee chain to safely open all the business systems.
