Description

A business processing method and device based on alliance chain system

The invention belongs to the field of network technology, and in particular relates to a business processing method and device based on an alliance chain system.

Blockchain technology has the natural characteristics of decentralization, and the mutual communication and mutual trust between network nodes can be realized through the consensus algorithm. The consortium chain in the blockchain is a blockchain maintained by several nodes. External nodes who want to join the consortium need to obtain the permission of the nodes in the consortium chain. In a network with a large number of nodes, where there is no trust between nodes and network connections become unpredictable, consensus protocols become increasingly important. The fault-tolerant protocol can provide strong security for the network and ensure the liveliness of the network.

At present, each functional module in the business system running in the consortium chain of the existing technology communicates with each other to complete the business processing, and finally uses the consensus algorithm to consensus the business processing results to ensure the consistency and accuracy of the business processing results. However, this method requires communication and cooperation between functional modules to complete business processing, which increases the working pressure of functional modules and reduces business processing efficiency.

Therefore, there is an urgent need for a business processing method and device based on an alliance chain system to reduce the working pressure of functional modules and improve business processing efficiency.

Embodiments of the present invention provide a business processing method and device based on an alliance chain system, which are used to reduce the working pressure of functional modules and improve business processing efficiency.

In the first aspect, the embodiment of the present invention provides a business processing method based on the consortium chain system. The consortium chain system includes multiple nodes, and any node is equipped with a business system that provides multiple business functions. Each Business functions are provided by a set number of nodes, and each node communicates based on a consensus mechanism. The method includes: For any transaction, when the first node in the consortium chain system determines that the business function to be executed by the transaction is the first business function it can provide, it processes the transaction based on the first business function and obtains the first processing result, And based on the consensus mechanism, the first processing result is consensused to each node in the alliance chain system; When the second node in the consortium chain system determines that the business function to be executed by the transaction is the second business function it can provide based on the first processing result, it processes the transaction based on the second business function and obtains the second processing result , and consensus the second processing result to each node in the consortium chain system based on the consensus mechanism, until the processing result of the last business function in the transaction is consensus to each node in the consortium chain system.

In the above method, a business system is set up in each node of the consortium chain, and a preset number of nodes corresponding to each business function in the business system are set to provide the business function. After each node receives the transaction, each node passes the consensus mechanism In instant messaging, the transaction is processed according to the transaction function in the business function, and the processing result is agreed, so that the node providing the next transaction function can process the next business function based on the processing result. Compared with the prior art of communicating with each other through the business function modules, the communication time consumption and the resource occupation of the business function modules can be greatly reduced.

Optionally, the business functions that can be provided by each node in the consortium chain system are determined by the following methods, including: For the business function with the highest priority among the business functions to be allocated, the alliance chain system determines the third node with the most free resources in the node resource information of each node based on the consensus mechanism, and sets the third node to provide the to-be-allocated The business function with the highest priority among the business functions, until the business functions to be allocated are all allocated.

In the above method, after the business system of the consortium chain is installed in each node, each node competes for business functions and/or transaction functions according to its own node resource information, and provides the highest priority business function and/or transaction function according to the node with the most idle resources in the node resource information. /or transaction functions. In this way, it can be ensured that business functions with high priority (high importance or resource demand) can have sufficient resources, and the normal operation of the business processing system of the alliance chain can be guaranteed as much as possible.

Optionally, the alliance chain system determines the third node with the most idle resources in the node resource information of each node based on the consensus mechanism, including: For any node, the alliance chain system determines the resource idle status of the node according to the weight of each resource in the node, the resource usage of each resource and the performance information of each resource; The alliance chain system determines the node with the most idle resources in the resource idle state as the third node based on the consensus mechanism.

In the above method, the resource idleness of each node in the consensus mechanism includes: the weight corresponding to each resource in the node, the resource usage of each resource, the performance information of each resource, and the resource occupation of the node providing business functions and other relevant information on resource items. It is convenient to determine the available resources of the node according to the resource idleness of the node, and then obtain the node with the most idle resources, and balance the node resources of the business function.

Optionally, the multiple business functions include a monitoring function, and the method also includes: The fourth node in the consortium chain system monitors each node based on the monitoring function it can provide; if it is determined that there is an abnormal node, an alarm is generated.

In the above method, the nodes are monitored, and if the node is abnormal, an alarm is generated. Improve operation and maintenance efficiency and ensure normal business processing.

Optionally, after determining the abnormal node, it also includes: The fourth node in the consortium chain system isolates abnormal nodes; The fourth node in the consortium chain system determines whether the number of nodes in the consortium chain that have the business functions provided by the abnormal node meets the set requirements; If the fourth node in the consortium chain system determines that the set requirements are not met, a resource replacement request is triggered in the consortium chain system; The consortium chain system determines a fifth node to replace the fourth node from the nodes based on a consensus mechanism.

In the above method, based on the consensus mechanism of each node, the alliance chain sets the business function corresponding to the set number of nodes, based on the set number of nodes to provide business functions, so that after the node failure of the set number of business function nodes, other nodes will dynamically compete Replacing the service function provided by the failed node can ensure that the service function is always provided based on the set number of nodes. Compared with the existing technology, in order to ensure the normal operation of the business system in the alliance chain, the staff set up corresponding nodes for each functional module in the business system in advance, so that each functional module has enough nodes to provide. If a node fails, the functions provided by the failed node are likely to be affected, and in severe cases, the operation of the business system will be affected. The present invention can make the node with the most abundant resources immediately take over the business function of the faulty node according to the node resource information when a fault occurs, so as to ensure that the business function of the faulty node has sufficient resources when the faulty node is repaired, further ensuring business System stability. Therefore, compared to the prior art where faulty nodes are manually determined and repaired, the repaired nodes or new nodes are configured to provide the function for a long period, which affects the operation of the business system, the present invention dynamically adjusts the business function node resources This method makes the business system insensitive to faulty nodes and improves the accuracy of business processing.

Optionally, the priority order of the first instruction sent by the node with the monitoring function in the consortium chain system is different from that of the second instruction sent by the node with the transaction function in the consortium chain system, and the priority order of the first instruction is high on the priority order of the second instruction.

In the above method, the priority of the first instruction sent by the node with the monitoring function in the consortium chain system is higher than the priority of the second instruction sent by the node with the transaction function in the consortium chain system. In this way, if the node with the monitoring function determines that the node with the transaction function has failed, it can make the node with the transaction function preferentially execute the first instruction when receiving the first instruction, preventing the faulty node from still executing the second instruction to perform transaction processing The resulting abnormal transaction processing ensures the accuracy of transaction processing.

In the second aspect, the embodiment of the present invention provides a consortium chain-based system. The consortium chain system includes multiple nodes, and any node is equipped with a business system. The business system provides multiple business functions, and each business function is passed through Provided by a set number of nodes, each node communicates based on a consensus mechanism; among them, nodes with transaction functions in the consortium chain system are used to process the transaction when it is determined that the business function to be executed by itself is a transaction function that can be provided by itself, and get Process the result, and consensus the processing result to each node in the alliance chain based on the consensus mechanism; until the processing result of the last transaction function in the transaction is consensus to each node in the alliance chain.

The above system is set as a node with a transaction function in the alliance chain system. When it is determined that the business function to be executed by the transaction is the transaction function that it can provide, it processes the transaction, obtains the processing result, and consensuses the processing result to the Each node in the alliance chain. In this way, compared with the direct communication between the functional modules in the alliance chain system in the prior art, the present invention can consensus the information between the functional modules and nodes through the consensus mechanism, improve the information transmission rate, and save Function module communication resources.

Optionally, it also includes: a node with a monitoring function in the consortium chain system, which is used to monitor each node in the consortium chain system, and generate an alarm when an abnormal node is determined.

In the above system, a node with monitoring function is set to monitor each node in the alliance chain system, and an alarm is generated when the node is abnormal. In this way, the efficiency of operation and maintenance is improved, and the normal processing of transaction business is guaranteed.

Optionally, the node with monitoring function is used to isolate abnormal nodes; A resource substitution request is triggered in the chain; the resource substitution request is used to determine a node to replace the abnormal node from among the nodes of the consortium chain system.

In the above system, the nodes with the monitoring function isolate the abnormal nodes when there are abnormal nodes. In this way, the accuracy of transaction business processing is guaranteed. When it is determined that the number of nodes with the business functions provided by the abnormal node in the consortium chain system does not meet the set requirements, a resource replacement request is triggered in the consortium chain, and the node used to replace the exception is determined from each node in the consortium chain system. node's node. In this way, ensuring a sufficient number of nodes to provide this business function will ensure the reliability and efficiency of transaction business processing.

Optionally, the priority order of the first instruction sent by the node with the monitoring function in the consortium chain is different from that of the second instruction sent by the node with the transaction function in the consortium chain, and the priority order of the first instruction is higher than that of the consortium chain. The priority order of the second directive.

In the above system, the priority order of instructions of nodes with a monitoring function is set higher than that of nodes with a transaction function. Effectively prevent the phenomenon of business processing errors caused by abnormal nodes still processing transaction business, and improve the reliability of business processing.

In the third aspect, the embodiment of the present invention provides a business processing device based on the consortium chain system. The consortium chain system includes multiple nodes, and any node is equipped with a business system. The business system provides multiple business functions. Each Business functions are provided by a set number of nodes, and each node communicates based on a consensus mechanism. The device includes: The determination module is used to process the transaction based on the first transaction function through the processing module to obtain the first processing result when it is determined that the business function to be executed by the transaction is the first transaction function that can be provided by itself for any transaction , and based on the consensus mechanism, the first processing result is consensused to each node in the alliance chain system; The determination module is used to determine that the business function to be executed in the transaction is the second transaction function that it can provide based on the first processing result, and process the transaction based on the second transaction function through the processing module to obtain the second transaction function. 2. Process the result, and consensus the second processing result to each node in the alliance chain system based on the consensus mechanism, until the processing result of the last transaction function in the transaction is consensus to each node in the alliance chain system.

These implementation manners or other implementation manners of the present invention will be more concise and understandable in the description of the following embodiments.

In order for Ligui examiners to understand the technical characteristics, content and advantages of the present invention and the effects it can achieve, the present invention is hereby combined with the accompanying drawings and appendices, and is described in detail in the form of embodiments as follows, and the drawings used therein , the purpose of which is only for illustration and auxiliary instructions, and not necessarily the true proportion and precise configuration of the present invention after implementation, so it should not be interpreted based on the proportion and configuration relationship of the attached drawings, and limit the application of the present invention in actual implementation The scope is described first.

In describing the present invention, it is to be understood that the terms "center", "lateral", "upper", "lower", "left", "right", "top", "bottom", "inner", " The orientations or positional relationships indicated in the drawings are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, Specific orientation configurations and operations, therefore, are not to be construed as limitations on the invention.

Fig. 1 is a schematic diagram of an architecture based on a consortium chain system provided by an embodiment of the present invention, wherein, a node 101 and its database 1, a node 102 and its database 2, a node 103 and its database 3, may participate in the consortium chain Corresponding service nodes of the same or different institutions, organizations, etc. of the system. Here, node 101 and its database 1, node 102 and its database 2, node 103 and its database 3 are just examples, and there is no limit to the number of nodes in the consortium chain system. There can be more than one service node for each institution and organization in the alliance chain system, and there is no limit to the number of institutions and organizations participating in the alliance chain system. The client 104 can be the client 104 of the node 101, and the client 104 can be used to obtain information in the business system based on the consortium chain system, or initiate a business processing request to the business system based on the consortium chain system. The management client 105 can be a management client 105 that performs corresponding management operations on the business system of the consortium chain system through the node 101, such as data configuration changes, system release changes, etc. Here, the service node of each institution may have a client terminal 104 and/or a management client terminal 105, which are set according to needs, and are not specifically limited here.

Each node in the alliance chain system is equipped with a business system, and different nodes in each node can provide the same or different business functions of the business system, and each business function is provided by a set number of nodes. For example, there are 20 nodes in the current consortium chain system, the business system is set to provide the identification function through 10 nodes, and the data configuration function is provided through 3 nodes, and the priority of the identification function is higher than that of the data configuration function. After the 20 nodes are installed and running in the business system, they first compete for the identification function according to the node's own resource information (the node with the most idle resources will first compete for the identification function, that is, among the current 20 nodes, the nodes with the top 10 idle resources provide identification. Function). When the number of nodes successfully competing for the identification function reaches 10, 20 nodes continue to compete for the data configuration function (preferably, for each business function or transaction function here, the full amount of nodes competes based on node resource information, and the basis for the competition is node Resource idle situation. In this way, the running speed of business functions/transaction functions can be guaranteed. The basis for contention can also be based on node resource information and the node’s business functions or transaction functions. For example, to compete for business functions or transaction functions provided by nodes Different business functions or transaction functions can be set according to the specific needs of business functions and transaction functions, and there is no limit here), so that the data configuration function is provided through 3 nodes. Store the last remaining nodes that do not provide business functions in the resource backup pool. When a node providing a service function is abnormal, other nodes outside the node compete for the service function provided by the abnormal node. In this way, in the normal business processing process, the identification function is always provided by 10 nodes, and the data configuration function is always provided by 3 nodes, which guarantees the resources required for the operation of business functions and further ensures the business system The speed of operation and the accuracy of business processing.

In an example, each organization can provide all business functions in the business system through multiple service nodes of the organization. For example, if the business system contains two business functions, and the organization runs the business system by node 101 and node 102, then node 101 can be provided with one business function, and node 102 can be provided with another business function. That is, the service node of an organization in the consortium chain system can also fully provide all the functions of the business system. Or, in yet another example, all business functions in the business system can also be provided for service nodes passing through all participants (institutions, organizations, etc.) in the alliance chain system. For example, if the business system includes two business functions, and the node 101 of organization 1 and the node 102 of organization 2 run the business system, node 101 can provide one kind of business function, and node 102 can provide another kind of business function. That is, the service nodes of all or some organizations in the consortium chain system can fully provide all the functions of the business system. Here, there is no restriction on the source of the node that provides business functions (the source of the node, which can be the organization to which the node belongs).

Each node in the alliance chain system is equipped with a business system, and each node communicates through a consensus mechanism. For example, the node 101 and the node 102 agree to process the processing result acquired by the transaction through a consensus mechanism. That is, in one example, if the transaction generation function provided by node 101 has a higher priority than the effective transaction function provided by node 102, after nodes 101 and 102 obtain the transaction, node 101 determines that the business function to be executed by the transaction is itself When the generated transaction function is provided, the transaction is processed, the processing result is obtained, and the processing result is consensused to the node 102 based on the consensus mechanism; when the node 102 determines that the business function to be executed by the transaction is an effective transaction function that it can provide, The processing result of the 101 consensus processes the transaction and obtains the processing result. If there is still a node 103 that provides a publishing transaction function with a lower priority than the effective transaction function, when it is determined that the business function to be executed by the transaction is a publishing transaction function that can be provided by itself, the transaction can be processed based on the processing results of the consensus of the node 102, and the obtained process result.

In addition, the consortium chain system can also include nodes with monitoring functions, monitor each node in the consortium chain system, and generate an alarm when an abnormal node is determined. It is also possible to isolate the abnormal nodes when there are abnormal nodes; Among the 10 nodes of the identification function, one node is abnormal, so that only 9 nodes provide the identification function, which does not meet the setting requirements provided by 10 nodes for the identification function), a resource replacement request is triggered in the alliance chain; from the alliance Among the nodes in the chain system, the node used to replace the abnormal node is determined (in the previous example, it is determined from the remaining 10 nodes (including the nodes in the resource backup pool and the 3 nodes that provide data configuration functions) node to replace the exception's node). Among them, in the alliance chain system, nodes with monitoring functions provide monitoring functions and are not used to compete for business functions other than monitoring functions. The first instruction sent by nodes with monitoring functions has a higher priority than the second instruction sent by nodes with transaction functions. Order of precedence for directives. In this way, it is ensured that the monitoring nodes can isolate abnormal nodes in time to ensure the reliability and accuracy of the operation of the business system.

Based on the above alliance chain system architecture, the embodiment of the present invention provides a schematic diagram of the architecture of a business system based on the alliance chain system, as shown in Figure 2, the business system based on the alliance chain system can realize identification functions, data configuration functions, and business processing functions 1. Monitoring function. Correspondingly, the business system may include an identification function module, a data configuration function module, a business processing function module, and a monitoring function module. Among them, the identification function is used to identify the business functions required to process transactions and the business functions provided by nodes, the data configuration function is used to provide business processing related parameters, the business processing function is used to process transactions, and the monitoring function is used to monitor transaction processing in the alliance chain Process and running status of each processing node. The business system here is just an example, and does not limit the business functions provided by the business system. For example, the business system can also provide node authorization functions (for example, authorize new nodes in the alliance chain system or abnormal nodes after repair to join the alliance chain system and business system, etc.). Business processing functions can also be divided into data collection functions, data generation functions, data validation functions, and data release functions. In one example, the institutions and organizations in the above alliance chain system may be in the same region or in different regions, for example, they may be in the same country or in different countries.

Based on the above alliance chain system architecture and the architecture of the business system based on the alliance chain system, the embodiment of the present invention provides a schematic flow diagram of a business processing method based on the alliance chain system. The alliance chain system includes multiple nodes. Both are equipped with a business system, the business system provides multiple business functions, each business function is provided by a set number of nodes, each node communicates based on a consensus mechanism, as shown in Figure 3, the method includes: Step 301. For any transaction, when the first node in the consortium chain system determines that the business function to be executed by the transaction is the first transaction function it can provide, it processes the transaction based on the first transaction function and obtains the first Processing results, and consensus on the first processing results to each node in the alliance chain system based on the consensus mechanism; Here, it should be noted that one or more transaction functions may be contained in a business function. Each transaction function can also be processed by a set number of nodes.

Step 302, when the second node in the consortium chain system determines that the business function to be executed by the transaction is the second transaction function that it can provide based on the first processing result, it processes the transaction based on the second transaction function, and obtains the second transaction function. 2. Process the result, and consensus the second processing result to each node in the alliance chain system based on the consensus mechanism, until the processing result of the last transaction function in the transaction is consensus to each node in the alliance chain system.

In the above method, a business system is set up in each node of the consortium chain, and a preset number of nodes corresponding to each business function in the business system are set to provide the business function. After each node receives the transaction, each node passes the consensus mechanism In instant messaging, the transaction is processed according to the transaction function in the business function, and the processing result is agreed, so that the node providing the next transaction function can process the next business function based on the processing result. Compared with the prior art of communicating with each other through the business function modules, the communication time consumption and the resource occupation of the business function modules can be greatly reduced.

An embodiment of the present invention provides a business processing method based on a consortium chain system. The business functions that can be provided by each node in the consortium chain system are determined in the following manner, including: for the business function with the highest priority among the business functions to be allocated, the The alliance chain system determines the third node with the most free resources in the node resource information of each node based on the consensus mechanism, and sets the third node to provide the business function with the highest priority among the business functions to be allocated until the Business functions are all assigned.

In one example, the identification function, data configuration function, business processing function, and monitoring function can be implemented in the business system, and the priority order of the business functions is: the priority of the identification function > the priority of the data configuration function > the priority of the business processing function Sequence>Priority of monitoring function, the business system is configured with 3 nodes corresponding to the identification function, 2 nodes corresponding to the data configuration function, 10 nodes corresponding to the business processing function, and 5 nodes corresponding to the monitoring function indivual.

Now install and run the business system in the 25 nodes in the consortium chain system, and the 25 nodes first compete for the identification function according to the node resource information of the node itself. First, the node with the most free resources among the 25 nodes competes for the recognition function, and then, the node with the most free resources among the 24 nodes currently providing the recognition function competes for the recognition function until the recognition function reaches the set number of nodes Requirement - 3 nodes to provide this recognition function.

Afterwards, the 25 nodes compete for the data configuration function based on their own node resource information, and the node with the most free resources among the 25 nodes competes for the data configuration function. Then, among the 24 nodes currently providing the data configuration function, the node with the most idle resources competes for the data configuration function until the data configuration function reaches the set number of nodes—2 nodes provide the identification function.

Afterwards, the 25 nodes first compete for the service processing function according to the node resource information of the node itself, and the node with the most idle resources among the 25 nodes competes for the service processing function. Then, among the 24 nodes currently providing the data configuration function, the node with the most idle resources competes for the business processing function until the business processing function reaches the set number of nodes—10 nodes provide the business processing function.

Afterwards, the 25 nodes compete for the monitoring function based on their own node resource information, and the node with the most idle resources among the 25 nodes competes for the monitoring function. Then, among the 24 nodes currently providing the monitoring function, the node with the most idle resources competes for the monitoring function until the monitoring function reaches the set number of nodes—5 nodes provide the monitoring function. It should be noted here that the fixed node can be determined to provide the monitoring function through manual setting or through other programs. That is, nodes with monitoring functions do not participate in the process of competing for business functions. In this way, the stability and traceability of monitoring functions provided by these fixed nodes are guaranteed, which is convenient for staff to operate and maintain. In addition, from the above example, it can be known that a node can provide one or more business functions at the same time, which is determined according to the node resource information of the node, and whether the node can compete for another business can also be determined according to the sufficiency of the business function resources currently provided by the node function, that is, the basis for competing for the service function to be provided currently is that the resource of the node is the most idle and the resource of the service function provided by the node is the most sufficient.

Here, there may be two factors for competing for the service function to be provided currently: idleness of node resources, and whether the resource of the service function provided by the node is sufficient. The method of competing for service functions based on these two factors of nodes can be specifically set as required. For example, a node has the most free resources, but the resource of the service function provided by the node (which may be the total idle resources of each node providing the service function) is lower than the sufficient resource threshold, then the node cannot compete for another service function. The node has the most idle resources, and the resource of the service function provided by the node (which can be the total idle resources of each node providing the service function) is higher than the resource adequacy threshold, then the node can compete for another service function.

An embodiment of the present invention provides a business processing method based on a consortium chain system. The consortium chain system determines the third node with the most free resources in the node resource information of each node based on a consensus mechanism, including: For any node, the alliance chain system determines the resource idle status of the node according to the weight of each resource in the node, the resource usage of each resource and the performance information of each resource; The alliance chain system determines the node with the most idle resources in the resource idle state as the third node based on the consensus mechanism.

In one example, the resource usage in the node resource information includes remaining memory, remaining numbers of various processes, etc., and the resource performance information includes: total server memory, server model, server production year, and so on. A larger weight will be set for the resource items that have a greater impact on the business functions provided by the node and/or have more applications, so that the weight of each resource in the node, the resource idleness calculated according to the resource usage of each resource and the performance information of each resource The situation is most consistent with the ability to characterize a node's ability to provide business functions.

In the business processing method based on the consortium chain system provided by the embodiment of the present invention, the multiple business functions include a monitoring function, and the method further includes: the fourth node in the consortium chain system monitors the Each node; if it is determined that there is an abnormal node, an alarm will be generated. That is to say, the fourth node is a monitoring node with monitoring function. The monitoring node is used to monitor the business processing status of each node in the consortium chain system and its own operation status. If the node has a specific business processing exception (such as transaction Processing waiting time exceeds the set threshold, etc.) or operation failure (for example, the cloud gateway recognizes that the node cannot communicate with other nodes through the consensus mechanism, etc.), and generates an alarm for the abnormal node, and can also isolate the abnormal node (you can The abnormal node can be isolated by closing the corresponding port of the abnormal node, etc.), and after the abnormal node is repaired, the node can be put into the resource backup pool.

A business processing method based on the consortium chain system provided by the embodiment of the present invention, after determining the abnormal node, further includes: The fourth node in the consortium chain system isolates abnormal nodes; The fourth node in the consortium chain system determines whether the number of nodes in the consortium chain that have the business functions provided by the abnormal node meets the set requirements; If the fourth node in the consortium chain system determines that the set requirements are not met, a resource replacement request is triggered in the consortium chain system; The consortium chain system determines a fifth node to replace the fourth node from the nodes based on a consensus mechanism. That is to say, after the monitoring node in the alliance chain system isolates the abnormal node, it needs to determine whether the business function provided by the abnormal node meets the set requirements of the number of nodes. If not, it needs to initiate a resource replacement request, from the alliance chain The fifth node is determined in the system to provide the service function, so that the number of nodes of the service function meets the set requirements. What needs to be explained here is that after the monitoring node isolates the abnormal node, it can determine whether to compete for the business function of the abnormal node through the consensus mechanism, and determine the fifth node through the consensus mechanism. Here, the resource replacement request is reached by the node consensus mechanism. a statement of.

In the business processing method based on the alliance chain system provided by the embodiment of the present invention, the difference between the first instruction sent by the node with the monitoring function in the alliance chain system and the second instruction sent by the node with the transaction function in the alliance chain system The priorities are different, and the priority of the first instruction is higher than that of the second instruction. That is to say, the communication of each node on the consortium chain system uses at least two sets of instructions. Instruction set A—the second instruction set is an instruction set for information interaction between nodes, and the header of the message may start with "000A". Instruction set B—the first instruction set is the intervention instruction issued by the monitoring function module, and the header of the message may start with "000B". When the monitoring node finds that there is an abnormality on the alliance chain system or any scene that requires manual intervention, it will issue an intervention instruction to the alliance chain system through a dedicated intervention instruction set - the first instruction. Messages of instruction set A will be queued and processed at each node. When receiving an instruction belonging to instruction set B, the node will give priority to processing without queuing. Each node sets up a dedicated execution thread pool for concurrent processing of information processing of instruction set B to ensure that the consensus intervention mechanism and business processing do not interfere with each other. In addition, in order to prevent instruction set B from being tampered with or forged, the sender of the intervening instruction set embeds his own signature information into the message header of instruction set B, and puts the time information of the initiation into the message body. After the node receives the instructions of the instruction set B, it first checks the validity of the identity of the sender of the message, and the instructions of the instruction set B that pass the verification will be truly followed and executed.

Based on the above method flow, the embodiment of the present invention provides a business processing method flow based on the alliance chain system, as shown in Figure 4, including: Step 401, setting relevant configuration data in the business system.

Here, the relevant configuration data can be the number of nodes of each business function in the business system, exchange rate data of different countries, the highest transaction volume within a set time, the maximum transaction amount of a transaction, and so on.

Here, the number of nodes that provide the transaction function corresponding to the transaction function can also be set for multiple transaction functions in some business functions.

Step 402, install the service system in the node and run it.

Here, the nodes are the nodes in the consortium chain system.

Step 403, each node running the business system competes for the business function provided by the node.

Here, the monitoring function may be provided by a set fixed node.

Step 404, each node obtains the transaction request.

Here, each node can obtain the transaction request through the consensus mechanism. In an example, the business system obtains a deposit transaction request submitted by a user terminal (for example, the information in the deposit transaction request includes storing a certain value of the first currency as the second currency). Then the data configuration function in the node obtains the exchange rate between the first currency and the second currency, which can be converted according to the exchange rate of the first currency and the second currency in the deposit transaction request according to the data generation function to obtain the second currency value. And the transaction data corresponding to the value of the second currency will be validated by the data validation function. The transaction data within the set time period will be released by the data release function. Here, compared with the collection, generation, validation and release of data through communication between functional modules in the prior art, the present invention completes the collection, generation, validation and release of data through a consensus mechanism to speed up business processing.

Step 405, among the nodes, the node that provides the identification function identifies the business function/transaction function among the business functions needed to process the transaction request. Through the consensus mechanism, the business functions required to process the transaction request/the transaction functions in the business functions are sent to each node.

For example, in the above example, the business functions required to process the transaction request include: data configuration function and business processing function, and the business processing function includes transaction functions such as data generation function, data validation function and data release function.

Step 406: Among the nodes, the node that provides the first business function determines that it provides the first business function, and among the nodes that provides the first transaction function in the first business function, it determines that it provides the first transaction function. A transaction function processes the transaction request, or processes the transaction request according to the processing result to obtain the processing result. The processing result obtained by the first transaction function is consensused to each node through a consensus mechanism.

Here, the first business function is: among the multiple business functions required to process the transaction request, the business function that is ranked first among the business functions that have not been provided for the transaction request.

The first transaction function is: among the plurality of transaction functions required by the first business function for processing the transaction request, the transaction function that has not been provided for the transaction request is the transaction function that ranks first.

Wherein, the first transaction function processes the transaction request according to the processing result and obtains the processing result. Process transaction requests.

Step 407, among the nodes, the node that provides the second transaction function in the first business function determines that it provides the second transaction function, and processes the transaction request according to the processing result to obtain the processing result through the second transaction function. The processing results obtained by the second transaction function are consensused to each node through a consensus mechanism.

Here, the second transaction function is a transaction function processed after the first transaction function.

Step 408: Among the nodes, the node that provides the second business function determines that it provides the second business function, and among the nodes that provide the first transaction function in the second business function, it determines that it provides the first transaction function. A transaction function processes the transaction request, or processes the transaction request according to the processing result to obtain the processing result. The processing result obtained by the first transaction function is consensused to each node through a consensus mechanism.

Here, the second business function is a business function that is processed after the first business function.

The first transaction function is: among the plurality of transaction functions required by the second business function for processing the transaction request, the transaction function that has not been provided for the transaction request is the transaction function that ranks the highest.

Wherein, the first transaction function processes the transaction request according to the processing result and obtains the processing result. Process transaction requests.

Step 409 , among the nodes, the node that provides the second transaction function in the second business function determines that it provides the second transaction function, and processes the transaction request according to the processing result to obtain the processing result through the second transaction function. The processing results obtained by the second transaction function are consensused to each node through a consensus mechanism.

Here, the second transaction function is a transaction function processed after the first transaction function.

Step 410, until the multiple business functions required to process the transaction request are all processed, and the final processing result is obtained.

Here, in the above example, the final processing result may be that the deposit is completed in the account corresponding to the second currency.

Step 411, the monitoring node determines that a node providing a certain service function is abnormal, and generates an alarm.

Step 412, the monitoring node isolates the abnormal node.

Step 413, each node competes for the service function based on the node resource information based on the consensus mechanism, and determines the node that provides the service function.

Step 414, the monitoring node determines the newly added node or the abnormal node after repair, and puts the node into the resource backup pool.

What needs to be explained here is. The above-mentioned method flow is not unique, for example, any step or multiple steps from step 411 to step 414 may be performed before and after any step from step 404 to step 409 . In addition, the transaction may also be generated by the operation of the business system itself, so step 404 does not need to be performed. Step 401 may be performed before or after any step in the process steps. Step 402 and step 403 may only be performed in processes requiring reinstallation such as business system update. Wherein, the method flow from step 406 to step 409 is just an example, which is specifically determined according to the number of business functions required to process the transaction request and the number of transaction functions in the business functions. Therefore, the above method flow does not limit the business processing method based on the consortium chain system, and can be adjusted according to specific needs.
