[0002] In a blockchain network, transactions need to go through three stages before they are finally recorded in the ledger: endorsement (execution), sorting, and verification. The endorsement stage is mainly used to ensure the validity of transactions, achieve consistency in business logic, provide data privacy and confidentiality, and enhance network security.

[0003] At present, the performance bottleneck of the endorsement system, especially the chain code execution time, limits the performance of the blockchain network when processing high-load and computationally intensive tasks. In order to solve the above problems, the endorsement system provided by the prior art pre-installs multiple chain code containers and implements parallel endorsement operations through multiple chain code containers. However, the chain code containers are pre-set, which may cause the problem of waste or insufficient endorsement resources under different load conditions. Summary of the invention

[0026] All actions to obtain signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located, and with the authorization given by the owner of the corresponding device.

[0027] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Please refer to Figure 1 , which shows a process 100 of an embodiment of a method for setting an endorsement system according to the present application. The method for setting an endorsement system can be applied to various electronic devices with data processing functions. For example, the above electronic devices may include but are not limited to cloud servers, physical servers, etc. The execution subject of the automatic discovery method of the topological relationship may be a processor in the above electronic device.

[0030] In this embodiment, the setting method of the endorsement system is applied to the elastic endorsement node of the blockchain network, and the elastic endorsement node can be connected to multiple chain code containers.

[0031] In this embodiment, the blockchain network may include: peer nodes, sorting nodes and clients. Among them, the peer node can play the role of an elastic endorsement node, and the chain code container is a container on the peer node, which is used for the chain code (smart contract) to run and is responsible for executing specific transaction logic.

[0032] like Figure 1 As shown, the method for setting up the endorsement system includes the following steps:

[0033] Step 101: Periodically obtain the resource usage of the chain code container.

[0034] In this embodiment, the resource usage rate of the chain code container may specifically be the CPU usage rate of the chain code container. Of course, in actual use, the resource usage rate of the chain code container may also be other performance data, and each case will not be described one by one this time.

[0035] It should be noted that this embodiment does not specifically limit the period for obtaining the resource usage rate of the chain code container described in step 101. In actual use, it can be set according to the load situation, which is not elaborated here.

[0036] Step 102: When the resource usage rate of the chain code container is greater than the first threshold, a first capacity expansion operation is performed on the number of chain code containers.

[0037] This embodiment does not limit the specific value of the first threshold, and it can be set according to needs during actual use.

[0038] And / or, step 103: when the resource usage rate of the chain code container is less than the second threshold, the number of chain code containers is reduced.

[0039] This embodiment does not limit the specific value of the second threshold, and it can be set according to needs during actual use.

[0040] In this embodiment, in order to more accurately adjust the number of chain code containers and ensure the rational use of resources. After step 102, it may also include: obtaining the transaction processing rate (Transactions Per Second, TPS) of the blockchain network; when the transaction processing rate is less than the third threshold, performing a second expansion operation on the number of chain code containers. Of course, the above steps are only specific examples of this embodiment. In actual use, the second expansion operation can also be determined based on the improvement effect of the transaction processing rate on the basis of the first expansion operation. For example: after the first expansion operation, if the TPS improvement effect is significantly improved, there is no need to perform the second expansion operation. Otherwise, continue to perform the second expansion operation. Among them, the significant improvement can be achieved by setting a fourth threshold. For example: if the TPS improvement effect is greater than the fourth threshold, it means that the improvement effect is significantly improved.

[0041] In this embodiment, the elastic endorsement node can set a container resource monitoring scaling component, and the above steps provided in this embodiment ( Figure 1 Steps 101-103 shown in the figure, as well as the additional steps after step 102) can all be completed by the container resource monitoring scaling component.

[0042] In this embodiment, the input data of the container resource monitoring scaling component may include: the CPU usage of the chain code container and the transaction processing rate of the blockchain network, and the output data may include: the result of dynamically adjusting the number of chain code containers, such as: expansion, reduction, and unchanged.

[0043] In this embodiment, the process of container resource monitoring scaling components may include:

[0044] 1. Orchestrator Adapter

[0045] function StartContainerAutoscaling

[0046] 2. Start automatic adjustment of chain code container

[0047] while true do

[0048] 3. Get the list of chaincode container services being monitored.

[0049] Monitor service list = Orchestrator adapter: ListMonitorContainer()

[0050] 4. Traverse the services and determine whether adjustments are needed.

[0051] foreach service in monitoring service list do

[0052] Current CPU usage = OrchestratorAdapter.ContainerCPUtilization(service)

[0053] Current number of chaincode containers = orchestratorAdapter.ContainerReplicaCount(service)

[0054] CurrentTPS=GetCurrentTPS()

[0055] 5. According to the current overall usage rate, the number of chain code containers, the number limit of chain code containers, and other information, check whether the TPS has increased to a certain extent since the first expansion operation to decide whether to perform the second expansion operation.

[0056] Expected number of chaincode containers = Calculate the expected number of chaincode containers (current CPU usage, current number of chaincode containers, current TPS)

[0057] 6. If the expected number of chaincode containers is different from the current number of chaincode containers, adjust the service scale.

[0058] If the expected number of chaincode containers! = the current number of chaincode containers then

[0059] OrchestratorAdapter.ScaleContainerService(service, expected number of chaincode containers)

[0060] end if end foreach

[0061] 7. Sleep for a while until the next monitoring cycle arrives

[0062] Sleep(MONITORING_INTERVAL_SEC)

[0063] end while end function

[0064] In this embodiment, if Figure 2 As shown, the first capacity expansion operation and / or the second capacity expansion operation may include the following steps:

[0065] Step 201: Determine the number of newly added chain code containers, and instruct the external builder to use the external elastic chain code construction mechanism to create newly added chain code containers according to the number of newly added chain code containers.

[0066] Step 202: Use the elastic chain code mechanism to perform a self-registration operation on the newly added chain code container and establish a connection with the newly added chain code container.

[0068] Step 301: Determine the chain code container to be reduced.

[0069] Step 302: Use the elastic chain code mechanism to perform a self-cancellation operation on the chain code container to be reduced.

[0070] In this embodiment, the elastic chain code mechanism includes a self-registration mechanism and a self-cancellation mechanism of the chain code container. Figure 2 and Figure 3 The input data for self-registration and self-cancellation through the elastic chain code mechanism shown in the steps are: peer address list, chain code ccid, chain code address ipaddress and heartbeat monitoring interval lease; the output data is: chain code service instance (chain code container).

[0071] In this embodiment, the process of self-registering and self-cancelling the chaincode container using the elastic chaincode mechanism may include:

[0072] 1. Register the service to the node and send heartbeats at a certain interval

[0073] RegisterService(PeerAddrList,ccid,ipaddress,lease)

[0074] 2. Self-cancellation

[0075] Parallel execution

[0076] Monitor system signals

[0077] If it is a termination signal

[0078] RevokeService()

[0079] }

[0080] 3. Self-registration

[0082] In this embodiment, if Figure 4 As shown, the method for setting the multiple system also includes the following steps:

[0083] Step 104: Monitor the activity of the chain code container through the service monitoring maintenance component to obtain the activity monitoring result.

[0084] Step 105: Dynamically manage the chain code container based on the activity monitoring results.

[0085] In this embodiment, the service monitoring maintenance component can not only be used to execute steps 104 and 105, but also to execute the above Figure 2 and Figure 3 The self-registration and self-cancellation steps shown in the figure. At this time, the input data of the service monitoring maintenance component is: registration request, cancellation request or heartbeat request; the output data is: registration confirmation response, cancellation confirmation response or heartbeat receipt.

[0086] In this embodiment, the specific process of the service monitoring maintenance component may include:

[0087] 1. Start the service monitoring and waiting for requests

[0088] Start service listener()

[0089] 2. Start monitoring loop

[0090] Loop

[0091] 3. Receive registration requests, deregistration requests or heartbeat requests.

[0092] Accept registration,unregistration,or heartbeat requests

[0093] 4. If it is a registration request: process registration, check connection information, check TLS certificate, and join the connection pool, where the connection pool consists of multiple chain code containers.

[0094] if registration:Handle registration,check registration,add toconnection pool

[0095] 5. If it is a logout request: close the connection and remove it from the connection pool

[0096] Else if unregistration:Close connection,remove from pool

[0105] In order to improve the processing capability of the endorsement stage, in this embodiment, the method for setting up the endorsement system may further include the following steps:

[0106] When the client initiates a transaction proposal, a load balancing component is used to evenly distribute endorsement requests among multiple chaincode containers, and connections of multiple chaincode containers are managed through lock-free queues and atomic operation strategies.

[0107] In this embodiment, the step of managing the connection of multiple chaincode containers through lock-free queues and atomic operation strategies can be specifically implemented by a service connection pool component. By managing the connection of multiple chaincode containers through lock-free queues and atomic operation strategies, the communication connection between the elastic endorsement node and the chaincode container can be efficiently reused in a multi-threaded environment, thereby reducing resource overhead and connection latency.

[0108] In this embodiment, the implementation steps of the service connection pool component and the load balancing component may include:

[0109] 1. Try to get the processor queue of the corresponding chain code from the connection pool

[0110] Procedure distributeRequest(chaincodeName,request)

[0119] handler.Execute(request)

[0120] 4.3. Put the processor back into the queue for next use

[0121] queue.Enqueue(handler

[0122] 4.4. End the processing flow

[0123] EndIf EndProcedure
