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 application.
For a better understanding of the present application, the terms of art to which the present application relates are explained as follows:

Block chain node: the process for providing the blockchain service runs in a server or cloud environment. In general, a server may run one or more blockchain nodes.

The service agent: a service, a request may be communicated to a real service through a service agent. Service agents may mask compatibility and complexity between services, provide load balancing capabilities, and the like.
Load balancing: for distributing load among multiple computers (computer clusters), network connections, CPUs, disk drives, or other resources for the purposes of optimizing resource usage, maximizing throughput, minimizing response time, while avoiding overload.
The existing blockchain application system includes a blockchain application service and a blockchain network, and the blockchain application service is connected with a plurality of blockchain link points in the blockchain network. The block chain application service records node information corresponding to all block chain link points connected with the block chain application service in a block chain network.
After the blockchain application service generates a transaction request, the blockchain application service determines to send the transaction request to a blockchain node connected with the blockchain application service in a blockchain network, and then the blockchain node broadcasts the transaction request to the whole blockchain network.
Fig. 1 schematically shows a deployment of a blockchain application system. The block chain application service is connected with 2 block chain nodes (block chain node 1, block chain link point 2) in the block chain network, and the block chain application service records node information of the block chain link point 1 and node information of the block chain link point 2.
Illustratively, after generating the transaction request, the blockchain application service sends the transaction request to the blockchain node 1, and the blockchain node 1 broadcasts the transaction request to the whole blockchain network.
Therefore, the blockchain application service needs to record node information corresponding to all blockchain link points connected with the blockchain application service in the blockchain network, and needs to determine a certain blockchain node from the blockchain nodes according to the node information corresponding to the blockchain link points and send a transaction request to the blockchain link point.
Thus, the requirement of the blockchain application system for the blockchain application service is high.
To solve the above technical problem, fig. 2 schematically illustrates a deployment diagram of another blockchain application system provided by the present application. The block chain application system comprises a block chain application service, a proxy application service and a block chain network, wherein the block chain application service is connected with the proxy application service, and the proxy application service is connected with a plurality of block chain link points in the block chain network.
The proxy application service records node information corresponding to all block chain link points connected with the proxy application service in a block chain network. After generating a transaction request, the blockchain application service sends the transaction request to an agent application service, the agent application service determines to send the transaction request to a blockchain node connected with the agent application service in a blockchain network, and the blockchain node broadcasts the transaction request to the whole blockchain network.
For example, as shown in fig. 2, the proxy application service is connected to 2 blockchain nodes (blockchain node 1, blockchain node 2) in the blockchain network, and node information of blockchain node 1 and node information of blockchain node 2 are recorded in the proxy application service. After generating the transaction request, the blockchain application service sends the transaction request to the proxy application service, and the proxy application service determines to send the transaction request to the blockchain node 1, so that the blockchain node 1 broadcasts the transaction request to the whole blockchain network.
In an alternative implementation, the proxy application service and the blockchain application service may be in a one-to-one correspondence, that is, one proxy application service corresponds to one blockchain application service. When the proxy application service is connected to the blockchain network, specifically, the proxy application service may be connected to a blockchain link point in the blockchain network, which is previously connected to the blockchain application service. Referring to fig. 1, the blockchain application service is connected to a blockchain node 1 and a blockchain node 2 in the blockchain network, and when the proxy application service is connected to the blockchain network, the proxy application service may be connected to the blockchain node 1 and the blockchain node 2 in the blockchain network.
In conjunction with the blockchain application system shown in fig. 2, the present application provides a transaction processing method that helps reduce the requirement of the blockchain application system for blockchain application services. The transaction processing method may be performed by a proxy application service, a blockchain application service, and a blockchain network.
The proxy application service may also be referred to as a general service, a blockchain general service, etc., and the blockchain application service may also be referred to as an application service, a business service, a blockchain application service, etc.
The proxy application service and the blockchain application service may be two services deployed on the same server or two services deployed on different servers.
Referring to fig. 3, a flow of the transaction processing method provided in the present application is described as follows.
In step 301, the blockchain application service generates a transaction request.
Wherein the transaction request is a transaction request to be sent to a blockchain network.
The blockchain application service may be software or application deployed in a business system, and when business personnel need to send a transaction request to a blockchain network, the blockchain application service may issue an instruction to the blockchain application service deployed in the business system, and the blockchain application service generates the transaction request according to the received instruction.
In step 302, the blockchain application service sends a transaction request to the proxy application service.
Accordingly, the proxy application service receives a transaction request from the blockchain application service.
In an alternative, the proxy application service is respectively connected to N block link nodes in the block link network, where N is a positive integer. Node information corresponding to each block chain link point in the N block chain nodes is recorded in the proxy application service. Illustratively, the node information corresponding to each block link node includes the operation state of the block link node and the number of processed transactions.
When the running state of the blockchain node is normal, the blockchain link point can receive a transaction request from the proxy application service, namely the blockchain node is in an available state, and the blockchain link point can be called as an available blockchain node; when the operation state of the blockchain node is abnormal, the blockchain link point cannot receive the transaction request from the proxy application service, that is, the blockchain node is in an unavailable state, and the blockchain link point can be called as an unavailable blockchain node.
In addition, the node information corresponding to each block link point may further include connection information of the block link node and the latest change time. Specifically, the connection information of the blockchain node may be an IP address and a port (computer port) of the blockchain node; the latest change time of the block chain node may be the latest change time of the node information corresponding to the block chain node.
In an optional manner, the proxy application service includes a node registration record, and node information corresponding to each block link point in the N block link nodes is recorded in the node registration record.
For example, the proxy application service is connected to the blockchain nodes 1 to 5 in the blockchain network, and the proxy application service includes a node registration record, where the node registration record records node information corresponding to each blockchain node in the blockchain nodes 1 to 5.
Illustratively, the node registration record may be a list of nodes. As shown in table 1, a node list provided in the embodiment of the present application is recorded with node information corresponding to a block link point, where the node information includes an operating state of the block link node, a processed transaction number, connection information, and a latest change time.
TABLE 1
| Operating state | Number of transactions processed | Connection information | Latest change time | |
| Block chain node 1 | Is normal | 10 | IP1+port1 | T1 |
| Block chain node 2 | Is normal | 12 | IP2+port2 | T2 |
| Block chain node 3 | Abnormality (S) | 14 | IP3+port3 | T3 |
| Block chain node 4 | Is normal | 5 | IP4+port4 | T4 |
| Block chain node 5 | Abnormality (S) | 9 | IP5+port5 | T5 |
In step 303, the proxy application service determines a first blockchain node from the N blockchain nodes.
The agent application service acquires a node registration record; and the agent application service determines the first block chain node according to the node information corresponding to the N block chain nodes.
In one implementation, the first blockchain link is in a normal operating state, and the processed transaction number of the first blockchain link meets the processed transaction number condition. For example, the processed transaction number condition is that the processed transaction number is smaller than the processed transaction number threshold, or the processed transaction number condition is that the processed transaction number in the node information corresponding to the block link point is the minimum.
In one implementation, the proxy application service may determine M blockchain nodes in a normal operating state according to an operating state of each of the N blockchain nodes; and then determining the block chain link point with the minimum processed transaction number as a first block chain node according to the processed transaction number of each block chain node in the M block chain nodes. Wherein M is less than or equal to N, and M is a positive integer.
Taking table 1 as an example, the proxy application service may determine block link point 1, block link point 2, and block link point 4 in a normal operation state according to the operation state of each of block link nodes from block link node 1 to block link point 5; the agent application service determines the number of processed transactions of each of the blockchain nodes 1, blockchain link points 2, and blockchain link points 4, determines that the blockchain link point in which the number of processed transactions is the smallest is the blockchain link point 4, and thereby determines the blockchain node 4 as the first blockchain node.
When determining the first blockchain node from the M blockchain nodes in the normal operation state, the agent application service may determine, as the first blockchain node, a blockchain node having the smallest number of processed transactions among the M blockchain nodes based on a load balancing algorithm, which is helpful for balancing the number of processed transactions processed by the M blockchain nodes.
For example, the embodiment of the present application provides a flow chart of processing a transaction request based on load balancing by a blockchain application system as shown in fig. 4.
at step 404, the first blockchain node processes the transaction request.
Step 304, the agent application service sends a transaction request to the first block link node.
After receiving the transaction request, the first blockchain node broadcasts the transaction request to the blockchain network, so that the agent application service sends the transaction request to the blockchain network through the first blockchain node.
In addition, the proxy application service may increase the number of processed transactions of the first blockchain node in the node information corresponding to the first blockchain node. Taking table 1 as an example, if the proxy application service determines the block link node 4 as the first block link node, the proxy application service adds 1 to the processed transaction number of the block link node 4 in the node information corresponding to the block link node 4, that is, the processed transaction number of the block link node 4 is 6.
In the technical scheme, the blockchain application service generates a transaction request, sends the transaction request to the proxy application service, determines a first blockchain node by the proxy application service, and sends the transaction request to the first blockchain node. The block chain application service does not need to record node information corresponding to the block chain link points and determine the first block chain node, and the requirement of a block chain application system on the block chain application service is favorably reduced.
In a specific implementation, the blockchain application service may be deployed in a business system, such as a banking business system, and this helps to reduce the complexity of the blockchain application service in the business system, and further helps to reduce the complexity of the business system.
In addition, the block link points to which the proxy application services are connected may be dynamically changed. Illustratively, the dynamic change may include any one of adding a node, deleting a node, recovering a service from a node, and disconnecting a service from a node. Accordingly, the node registration record in the proxy application service may be dynamically changed.
With the architecture shown in fig. 2, the dynamic change of the blockchain node connected to the proxy application service and the dynamic change of the node registration record may correspond to the following four cases:
in case 1, if a block link is newly added to connect with the proxy application service, the node information corresponding to the block link is newly added to the node registration record. For example, if a blockchain node 5 is newly added to the blockchain network and the blockchain node 5 is connected to the proxy application service, the node information corresponding to the blockchain node 5 may be newly added to the node registration record. For another example, if the blockchain node 4 in the blockchain network is connected to the proxy application service, the node information corresponding to the blockchain node 4 may be newly added in the node registration record.
In case 2, if a certain blockchain node connected to the proxy application service is deleted, the node information corresponding to the blockchain node is deleted from the node registration record. For example, if the blockchain node 2 in the blockchain network is deleted, that is, the blockchain node 2 is deleted from the blockchain link point connected to the proxy application service, the node information corresponding to the blockchain node 2 may be deleted in the node registration record. For another example, the node information corresponding to the blockchain node 2 may be deleted in the node registration record, while the blockchain node 2 is not deleted from the blockchain network, but the blockchain node 2 may be deleted from the blockchain node connected to the proxy application service.
In case 3, if there is a certain block link node connected to the proxy application service but the operation is abnormal in the plurality of block link nodes connected to the proxy application service, the proxy application service sets the operation state of the block link node in the node registration record to be abnormal. For example, when the proxy application service detects that the blockchain node 2 runs abnormally, the running state in the node information corresponding to the blockchain node 2 in the node registration record is set to be abnormal.
And 4, in a plurality of block chain nodes connected with the proxy application service, if a certain block chain link point is connected with the proxy application service and the operation is recovered to be normal from abnormal operation, the proxy application service sets the operation state of the block chain link point in the node registration record to be normal. For example, when the agent application service detects that the blockchain node 2 is restored from abnormal operation to normal operation, the operation state in the node information corresponding to the blockchain node 2 in the node registration record is set to normal.
It should be noted that, in the above case 3, it should be understood that the block link point is not disconnected from the proxy application service, or the node information corresponding to the block link point is not deleted from the node registration record of the proxy application service, and the block link point simply cannot receive the transaction request from the proxy application service. Further, in case 4, it should be understood that, when the blockchain node resumes normal operation, the blockchain node may receive a transaction request from the proxy application service, so that the proxy application service may set the operation state in the node information corresponding to the blockchain node to be normal.
In the embodiment of the application, the proxy application service may be set to detect respective heartbeat information of the N block link points, so as to determine the running states of the block link nodes in the node information respectively corresponding to the N block link points according to the respective heartbeat information of the N block link points.
Taking any one of the N block chain nodes as an example for illustration, the proxy application service determines heartbeat information of the block chain node in a preset time period; and updating the running state of the block chain nodes in the node information corresponding to the block chain node points according to the heartbeat information.
In the embodiment of the present application, if node information is newly added to the node registration record, the proxy application service may also detect heartbeat information of the newly added blockchain node. Specifically, the agent application service determines a second block link node to be added to the block link nodes according to the node record information; and establishing connection between the proxy application service and the second block link point, and updating the node information corresponding to the second block link point in the node record information.
The agent application service may determine an operating state of the second blockchain node according to the heartbeat information of the second blockchain node, and set the processed transaction number of the second blockchain node as an initial value. Illustratively, the number of processed transactions for the second blockchain node is set to an initial value of 0.
Illustratively, fig. 5 is a schematic flow chart provided by an embodiment of the present application, where the flow is executed by the proxy application service as follows:
in step 509, the running status of the block link point that has not received the heartbeat information in the node registration record is set as abnormal.
According to the technical scheme, the heartbeat connection with the N blockchain nodes is established in the proxy application service, and the heartbeat information of each blockchain node in the N blockchain nodes is obtained, so that the running states of the N blockchain nodes are determined and updated to the node registration record, the running states of the N blockchain nodes in the node registration record are maintained to be the latest running states, and the proxy application service is favorably prevented from sending the transaction request to the blockchain node in the abnormal running state.
Further, when detecting that the node registration record contains the newly added node information, the proxy application service may perform heartbeat detection on the newly added blockchain node corresponding to the newly added node information, and update the running state of the newly added blockchain node to the node registration record in time.
Based on the same inventive concept, fig. 6 exemplarily shows a schematic structural diagram of a proxy application service provided by an embodiment of the present application. The proxy application service may include node registration records 601, load balancing 602, node listening 603, and transaction request proxy 604.
Illustratively, the node registration record 601 is used to store N pieces of node information corresponding to N block link points, respectively.
The node monitor 603 is configured to obtain N pieces of node information corresponding to the N block link points of the node registration record 601. The node monitor 603 is further configured to communicate with the N block link points, detect heartbeat information of the N block link points, and further determine whether the block link points are in a normal operating state. When a node of a blockchain is abnormal, which causes a heartbeat timeout of the blockchain, the node monitor 603 updates the running status of the blockchain node in the node registration record 601 to be abnormal. And when the heartbeat of the newly added block chain node or the block chain link point in the abnormal operation state is recovered, updating the operation state of the block chain node to be normal.
The load balancing 602 is configured to obtain an available node record of the node registration record 601, and determine a block chain node (i.e., a first block chain node) whose processed transaction number meets the condition of the processed transaction number according to the processed transaction number in the node information corresponding to each block chain node in the available node record.
The transaction request agent 604 is configured to receive a transaction request from a blockchain application service and send the transaction request to the first blockchain node. The transaction request agent 604 is also used to update the number of transactions processed for the first blockchain node.
In the embodiment of the application, the decoupling between the blockchain application service and the blockchain network is realized through the proxy application service, so that the blockchain application service does not directly interact with the blockchain network, and because the access address of the proxy application service is fixed and unchangeable, the blockchain application service cannot be influenced no matter how the blockchain nodes in the blockchain network change, and the normal operation of the blockchain application service is ensured.
