Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with one or more embodiments of this specification. Rather, they are merely examples of apparatus and methods consistent with some aspects of one or more embodiments of this specification, as recited in the appended claims.

It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described in this specification. In some other embodiments, the method may include more or fewer steps than described in this specification. In addition, a single step described in this specification may be decomposed into multiple steps for description in other embodiments; and multiple steps described in this specification may also be combined into a single step in other embodiments. describe.

FIG. 1 is a schematic diagram of a network architecture provided by an exemplary embodiment. As shown in FIG. 1 , after the service terminal 11 generates a processing request, it sends the processing request to the blockchain gateway 12, and the blockchain gateway 12 creates a blockchain transaction for the processing request, and submits the blockchain transaction to The blockchain network 13 enables the blockchain nodes on the blockchain network 13 to execute the blockchain transaction. When there is a need for stress testing (referred to as “stress testing”) for the blockchain network 13, the service end 11 can generate a processing request of the stress testing request type (including data for stress testing), and the blockchain gateway 12 can These stress testing requests create corresponding blockchain transactions, and these blockchain transactions are executed by the blockchain network 13 to stress test the blockchain network 13; and, the blockchain gateway 12 executes the blockchain network 13 The transaction receipt generated by the blockchain transaction is fed back to the business end 11, so that after the business end 11 analyzes the transaction receipt, the pressure test result of the blockchain network 13 is determined. In the production environment, the interaction process between the business end 11, the blockchain gateway 12 and the blockchain network 13 is similar to the above-mentioned stress measurement process: the business end 11 generates a processing request of the business request type, and the blockchain gateway 12 creates corresponding blockchain transactions for these business requests, and executes these blockchain transactions by the blockchain network 13; and, the blockchain gateway 12 sends the transaction receipts generated by the blockchain network 13 to execute the blockchain transactions Feedback to the service end 11 .

In the full-link stress testing scenario, it involves stress testing in the production environment. In order to avoid mutual interference between the above-mentioned stress test request and service request, the service terminal 11 can add a stress test label to the service request to distinguish it from the service request; of course, it can also add a service label to the service request to distinguish it from the stress test ask. However, when the blockchain gateway 12 creates a blockchain transaction, since it needs to abide by the relevant regulations such as the existing transaction format, it cannot distinguish the blockchain transactions corresponding to different processing requests, that is, the above pressure measurement label cannot be used. or business tags and other characteristic tags are brought into the blockchain network 13, so that the transaction receipts generated by the blockchain network 13 cannot carry the above-mentioned characteristic tags, so that the business end 11 cannot effectively distinguish the source of the transaction receipts, and cannot be accurate accordingly. Obtain the pressure test results of the blockchain network 13.

The stress testing scheme of this specification will be described below with reference to the embodiments.

The stress testing system of the blockchain network in this specification includes the business end, the business blockchain network and the stress testing blockchain network. Among them, the business end initiates a blockchain transaction to the business blockchain network in the production state; when the business blockchain node in the business blockchain network is a stress test transaction, it sends a transaction to the business area. The peer-to-peer stress testing blockchain network forwards the stress testing transaction, and executes the business transaction if the blockchain transaction is a business transaction; the stress testing blockchain node in the stress testing blockchain network executes The stress test transaction forwarded by the business blockchain node.

The operations performed by all parties in the stress testing system of the blockchain network are described in detail below.

Please refer to FIG. 2, which is a flowchart of a method for stress testing a blockchain network provided by an exemplary embodiment. As shown in Figure 2, the method is applied to a business blockchain node in a business blockchain network in a production state, and may include the following steps:

Step 202, identifying the transaction type of the blockchain transaction initiated by the service end.

In this embodiment, the blockchain client is used to create a blockchain transaction and submit the created blockchain transaction to the business blockchain network. Therefore, the business end can initiate blockchain transactions to the business blockchain network through the blockchain client.

In one case, the blockchain client can be deployed on the business end, and the business end directly interacts with the business blockchain network through the blockchain client to create corresponding blockchain transactions and submit them to the business blockchain network to meet actual needs. When there is a stress test requirement for the business blockchain network, the business side can create a stress test type blockchain transaction (ie, stress test transaction, including data used for stress test) through the blockchain client. When the blockchain network has business requirements, the business end can create business-type blockchain transactions (that is, business transactions, including data used to implement the business) through the blockchain client.

As an exemplary embodiment, a stress test transaction and a business transaction can be distinguished by adding a type identifier to the blockchain transaction. For example, the first type identifier can be added to the stress test transaction, and the second type identifier can be added to the business transaction. Then, after receiving the blockchain transaction submitted by the business end, the business blockchain node in the business blockchain network can read the type identifier contained in the received blockchain transaction. In the case where the type identifier is the first type identifier, the received blockchain transaction is determined as a stress test transaction, and in the case where the type identifier is the second type identifier, the received blockchain transaction is determined as business transaction.

Correspondingly, when the stress test transaction is executed to generate the first transaction receipt, a first type identifier may be added to the first transaction receipt to indicate that the first transaction receipt corresponds to the stress test transaction. Similarly, when the second transaction receipt is generated by executing the business transaction, a second type identifier may be added to the second transaction receipt to indicate that the second transaction receipt corresponds to the business transaction. That is, the first transaction receipt corresponding to the stress test transaction contains the first type identifier, and the second transaction receipt corresponding to the business transaction contains the second type identifier. Then, after obtaining the returned transaction receipt, the business end can identify the type of the transaction receipt according to the type identifier in the transaction receipt, and then store the first transaction receipt in the stress test database, and store the second transaction receipt in the business database. facilitate subsequent analysis. It can be seen that through the above improvements in the way of creating blockchain transactions, feature tags such as pressure measurement labels and business labels can be brought into the blockchain network, thereby realizing the transmission of pressure measurement attributes in the blockchain network.

As for the method of adding type identification, in one case, a type field (or any other field) can be added to the blockchain transaction to mark the blockchain transaction as a business transaction or a stress measurement transaction. For example, when the value of the type field of any blockchain transaction is the first value, it indicates that the blockchain transaction is a business transaction, and when the value of the type field of any blockchain transaction is the second value (the difference is When the value is the first value), it indicates that the blockchain transaction is a stress test transaction. Correspondingly, the type field can also be added to the transaction receipt to mark whether the transaction receipt is generated by executing a business transaction or by executing a stress test transaction, then the business end can identify the type field according to the above after obtaining the transaction receipt. The method of taking the value to identify the type of transaction receipt, and then carry out differentiated processing. In another case, existing fields in blockchain transactions and transaction receipts can also be reused, and type identifiers can be added to the existing fields. For example, the "reserved field" in the blockchain transaction is reused to indicate the transaction type of the blockchain transaction; for example, a business tag can be added to the "reserved field", so that the blockchain nodes on the blockchain network can A blockchain transaction that includes a business tag is identified as a business transaction, while a blockchain transaction that does not include a business tag is identified as a stress test transaction. Alternatively, a stress test tag can be added to the "reserved field", so that the blockchain node can identify the blockchain transaction that contains the stress test tag as a stress test transaction, and the blockchain transaction that does not contain the stress test tag is recognized as business transaction. Alternatively, a business tag and a stress measurement tag can be added to the "reserved field" at the same time, so that the blockchain node can identify the blockchain transaction containing the business tag as a business transaction, and identify the blockchain transaction containing the stress measurement tag. For the stress test transaction. It should be noted that, the method of adding the type identifier to the transaction receipt is similar to the above, and will not be repeated here.

In another case, the blockchain client is deployed on a business blockchain node in a business blockchain network. For example, two sets of logic codes are deployed on node devices in a business blockchain network. The first set of logic codes corresponds to the blockchain client, and the node device runs the first set of logic codes so that the off-chain business end can exchange data with the business blockchain network through the blockchain client. The second set of logic codes corresponds to the business blockchain network (that is, the chain code of the business blockchain network), and the node devices act as business blockchain nodes in the business blockchain network by running the second set of logic codes.

For example, the service end can send a processing request to the node device in the service blockchain network to realize interaction with the service blockchain network. The processing request may include a stress test request for invoking a stress test blockchain network to perform a stress test, a business request for invoking a business blockchain network to perform a production business, and the like. After receiving the processing request from the business end, the node device identifies the request type of the processing request through the blockchain client, creates a blockchain transaction corresponding to the request type, and submits the blockchain to the business blockchain network. trade. At the same time, the node device, as the business blockchain node in the business blockchain network, obtains the blockchain transaction submitted by the blockchain client, and identifies the transaction type of the blockchain transaction.

Among them, the processing request of the business end may contain a type identifier, and the blockchain client can identify the request type of the processing request accordingly. Further, when creating a blockchain transaction corresponding to the processing request, the blockchain client can also add a type identifier to the blockchain transaction to mark the transaction type of the blockchain transaction. Therefore, the transaction type of the blockchain transaction can be determined according to the type identifier contained in the obtained blockchain transaction. Taking the processing request divided into stress test request and service request as an example, the stress test request contains the first type identifier, and the service request contains the second type identifier. After the processing request is a stress test request, a corresponding stress test transaction can be created, and the first type identifier can be added to the stress test transaction. Similarly, after identifying the received processing request as a business request according to the second type identifier, the blockchain client can create a corresponding business transaction, and add the second type identifier to the business transaction.

Step 204, in the case that the blockchain transaction is a stress testing transaction, forward the stress testing transaction to a stress testing blockchain network equivalent to the business blockchain network.

In this embodiment, in order to avoid mutual interference between stress testing and production services, a stress testing blockchain network for responding to stress testing transactions and a business blockchain network for responding to business transactions can be deployed separately. Among them, the pressure measurement blockchain network is a blockchain network equivalent to the business blockchain network.

Further, the blockchain nodes in the business blockchain network cooperate with the business end and the blockchain network to realize data interaction between the business end and the business blockchain network and the pressure measurement blockchain network. Specifically, when the business blockchain node in the business blockchain network in the production state receives a blockchain transaction that is a stress testing transaction, it forwards the stress testing transaction to the stress testing blockchain network, so that the The stress testing blockchain node in the stress testing blockchain network responds to the stress testing transaction. When the business blockchain node receives the blockchain transaction as a business transaction, it directly executes the business transaction to realize the corresponding business. It can be seen that in the stress measurement scheme in this specification, the business blockchain node in the business blockchain network directly obtains the blockchain transaction initiated by the business end and identifies the transaction type of the blockchain transaction. It should be understood by those skilled in the art that: in the case where the business end needs to interact with the business blockchain network (that is, the business end needs to call the business blockchain network to realize the production business), if the business end is independent of the business end and the district The blockchain gateway of the blockchain network (including the business blockchain network and the stress test blockchain network) receives the blockchain transactions created by the business side, and identifies the transaction type and distributes the blockchain to the corresponding blockchain network. transaction, or the blockchain gateway creates the corresponding blockchain transaction in response to the processing request sent by the business end, and then distributes the created blockchain transaction to the corresponding blockchain network, then the business end and the business blockchain One more hop between the networks will cause a certain delay due to the distribution of the blockchain gateway, and the business blockchain network cannot obtain business transactions in time to respond, thus reducing the efficiency of business implementation.

However, the pressure measurement solution in this specification cancels the above-mentioned blockchain gateway used for data interaction between the business end and the blockchain network, and the business blockchain node in the business blockchain network performs the above distribution operation on its behalf. When the business end needs to interact with the business blockchain network, there is one less hop between the business blockchain node in the business blockchain network and the business end, and the business transaction initiated by the business end can be directly obtained. As a result, the delay can be reduced, the speed of responding to business transactions can be improved, and the efficiency of business realization can be improved. At the same time, the business end can initiate a stress test transaction within a specified time period. For example, the specified time period can be a time period when business data traffic is at a trough, such as late night, to avoid business peak periods. Then, even if the business blockchain node in the business blockchain network performs the operation of distributing blockchain transactions, it will not impose a processing burden on the business blockchain network.

Step 206, in the case that the blockchain transaction is a business transaction, execute the business transaction.

For ease of understanding, in the following, in conjunction with Figure 3, the blockchain client is deployed on the business end (that is, the business end creates blockchain transactions) as an example, and the blockchain client is deployed on the business blockchain node. The scheme above is similar.

As shown in FIG. 3 , a peer-to-peer stress-testing blockchain network 33 can be deployed for the business blockchain network 32 in the production state, so that the business blockchain network 32 is used to implement production services, and the stress-testing blockchain network 33 Used to implement stress testing. Among them, the stress test blockchain network 33 is completely equivalent to the business blockchain network 32, and has the same network structure and network configuration (including hardware and software configuration), so that the stress test implemented for the stress test blockchain network 33 It can reflect the real status of the business blockchain network 32 . For example, the machine resources, network resources, computing resources, and storage resources of the pressure measurement blockchain network 33 and the business blockchain network 32 are the same. At the same time, since the pressure measurement blockchain network 33 is completely equivalent to the business blockchain network 32, there is no need to modify the existing blockchain network when configuring the pressure measurement blockchain network 33, such as directly deploying the business area. The pressure measurement blockchain network 33 can be deployed in the way of the blockchain network 32, which is relatively simple in technical implementation and avoids the problem of increasing deployment costs due to complex technical implementation.

When there is a stress test requirement for the business blockchain network 32, the business end 31 may create a stress test transaction, and the stress test transaction includes a first type identifier (eg, a stress test label) and data for performing a stress test. When there is a business requirement for the business blockchain network 32, the business end 31 can create a business transaction, and the business transaction includes a second type identifier (such as a business tag) and data for implementing the production business. Then, the business end 31 can submit the created blockchain transaction to the business blockchain network 32 . In fact, regardless of whether the business end 31 creates a business transaction or a stress test transaction, the business end 31 directly interacts with the business blockchain network 32, that is, the business end 31 only perceives the business blockchain network 32 and does not need to perceive pressure. Testing blockchain networks33. For example, the service terminal 31 only needs to perceive the IP addresses of the service blockchain nodes in the service blockchain network 32 to communicate with them, without sensing the IP addresses of the stress testing blockchain nodes in the stress testing blockchain network.

After receiving the blockchain transaction, the business blockchain node in the business blockchain network 32 needs to read the type identifier contained in the blockchain transaction to identify its transaction type, so as to identify the different transaction types. Blockchain transactions are differentiated. When the received blockchain transaction is a business transaction, the business blockchain nodes in the business blockchain network 32 perform operations such as consensus, execution, and uploading of the business transaction, and generate a corresponding transaction receipt. For example, the business end 31 can send the created blockchain transaction to a certain business blockchain node 32n in the business blockchain network 32, and the business blockchain node 32n needs to understand the received blockchain transaction. The transaction type is identified to determine whether the blockchain transaction is a business transaction or a stress test transaction. When it is determined that the blockchain transaction is a business transaction, the blockchain node 32n can further transmit the business transaction to other blockchain nodes in the business blockchain network 32, so that all the blockchain nodes in the business blockchain network 32 The business blockchain node can perform operations such as consensus, execution, and uploading of the business transaction, and generate a corresponding transaction receipt (including the second type of identification, that is, the above-mentioned business label).

When the business blockchain node in the business blockchain network 32 identifies that the received blockchain transaction is a stress test transaction, the business blockchain node in the business blockchain network 32 forwards the stress test transaction to The stress-testing blockchain network 33, so that the stress-testing blockchain nodes in the stress-testing blockchain network 33 perform operations such as consensus, execution, and uploading of the stress-testing transaction, and generate a corresponding transaction receipt (including the first Type identification, i.e. the pressure test label above).

For the real data generated in the physical world, it can be constructed into a standard transaction format supported by the blockchain network, and then published to the blockchain network. Consensus processing is performed, and after reaching a consensus, the node device (that is, the blockchain node) as the accounting node in the blockchain network will package the transaction into the block and store it persistently in the blockchain network. certificate. Specifically, the business blockchain network 32 performs consensus processing on the received business transaction by all business blockchain nodes in the business blockchain network 32, so as to execute the business transaction and transfer the business transaction after the consensus is passed. The business transaction is packaged into the block. Similarly, the stress testing blockchain network 33 performs consensus processing on the received stress testing transaction by all stress testing blockchain nodes in the stress testing blockchain network 33, so that the stress test is executed after the consensus is passed. test transaction and package the stress test transaction into the block.

Among them, the consensus algorithms supported in the blockchain network can include:

The first type of consensus algorithm is the consensus algorithm in which node devices need to compete for the accounting rights of each round of accounting cycles; for example, Proof of Work (POW), Proof of Stake (POS), delegation Consensus algorithms such as Delegated Proof of Stake (DPOS);

The second type of consensus algorithm is a consensus algorithm that pre-selects billing nodes for each round of billing cycle (without competing for billing rights); for example, consensus algorithms such as Practical Byzantine Fault Tolerance (PBFT).

In a blockchain network using the first type of consensus algorithm, all node devices competing for the right to bookkeeping can execute the transaction after receiving the transaction. One of the node devices competing for the accounting right may win in the process of competing for the accounting right in this round and become an accounting node. The accounting node can package the received transaction with other transactions to generate the latest block, and send the generated latest block or the block header of the latest block to other node devices for consensus.

In the blockchain network using the second type of consensus algorithm, the node equipment with accounting rights has been negotiated before this round of accounting. Therefore, after the node device receives the transaction, if it is not the accounting node of the current round, it can send the transaction to the accounting node. For the accounting node of this round, the transaction may be executed during or before the process of packaging the transaction with other transactions to generate the latest block. After the accounting node generates the latest block, it can send the latest block or the block header of the latest block to other node devices for consensus.

As mentioned above, no matter which consensus algorithm shown above is adopted by the blockchain network, the accounting node of this round can package the received transactions to generate the latest block, and use the generated latest block or the latest block to generate the latest block. The block header of the block is sent to other node devices for consensus verification. If other node devices receive the latest block or the block header of the latest block and verify that there is no problem, the latest block can be appended to the end of the original blockchain network, thereby completing the accounting of the blockchain network process. In the process of verifying the new block or block header sent by the accounting node, other nodes can also execute the transactions contained in the block.

However, there are certain differences in the way that the business blockchain nodes in the business blockchain network 32 forward the stress testing transactions to the stress testing blockchain network 33, depending on how the business blockchain nodes and the stress testing blockchain nodes are configured. .

On the one hand, there are two situations in the way of forwarding stress testing transactions to the stress testing blockchain network. In one case, since the stress testing blockchain network 33 is a blockchain network equivalent to the business blockchain network 32, the number of stress testing blockchain nodes in the stress testing blockchain network 33 and the business blocks The number of business blockchain nodes in the chain network 32 is the same, that is, the pressure measurement blockchain node and the business blockchain node have a one-to-one correspondence. Therefore, the business blockchain nodes in the business blockchain network 32 can send pressure measurement transactions to the corresponding pressure measurement blockchain nodes in the pressure measurement blockchain network 33, so that each business blockchain node can send the corresponding The stress testing blockchain nodes forward the stress testing transactions peer-to-peer.

For example, it is assumed that the corresponding relationship between the business blockchain nodes in the business blockchain network 32 and the stress testing blockchain nodes in the stress testing blockchain network 33 is shown in Table 1.

Then, the business blockchain node A forwards the stress testing transaction to the stress testing blockchain node a, the business blockchain node B forwards the stress testing transaction to the stress testing blockchain node b, and the business blockchain node C forwards the stress testing transaction to the stress testing blockchain node b. The stress testing blockchain node c forwards the stress testing transaction, and the business blockchain node D forwards the stress testing transaction to the stress testing blockchain node d.

In another case, different from the above-mentioned peer-to-peer forwarding method, the business blockchain node in the business blockchain network 32 sends pressure to all the stress testing blockchain nodes in the stress testing blockchain network 33 respectively. Test transactions. For example, following the example in Table 1 above, the business blockchain node A forwards the stress testing transaction to the stress testing blockchain nodes a~d respectively, and the business blockchain node B sends the stress testing blockchain node a to the stress testing blockchain node a respectively. ~d forwards the pressure measurement transaction, the business blockchain node C forwards the pressure measurement transaction to the pressure measurement blockchain nodes a~d respectively, and the business blockchain node D forwards the pressure measurement transaction to the pressure measurement blockchain nodes a~d respectively. Test transactions.

On the other hand, the business end 31 submits a stress test transaction to the business blockchain node in the business blockchain network 32, while the business end 31 (there may be multiple ones) can submit multiple stress test transactions to different The business blockchain node submits the stress test transaction. Therefore, for the forwarded stress test transaction, there are two situations. In one case, any service blockchain node in the service blockchain network 32 can forward the stress measurement transaction received by the service blockchain node from the service terminal 31 to the stress measurement blockchain network 33 . Taking the above-mentioned situation of "one-to-one correspondence" between the pressure measurement blockchain node and the business blockchain node as an example, the business blockchain node A can forward the business blockchain node A to the pressure measurement blockchain node A from the business end 31. For the 50 pressure measurement transactions received at 31, the business blockchain node B can forward the 40 pressure measurement transactions received by the business blockchain node B from the business terminal 31 to the pressure measurement blockchain node b. The business blockchain Node C can forward the 30 pressure measurement transactions received by the business blockchain node C from the service terminal 31 to the pressure measurement blockchain node c, and the business blockchain node D can forward the business area to the pressure measurement blockchain node d The 20 pressure measurement transactions received by the blockchain node D from the service terminal 31. After each stress testing blockchain node receives the stress testing transaction, it can broadcast the stress testing transaction it has received in the stress testing blockchain network, so that all stress testing blockchain nodes can obtain the same stress testing transaction. , and then all stress testing blockchain nodes can perform consensus, execution, and chaining operations for these same stress testing transactions. For example, the stress testing blockchain node a can broadcast the 50 stress testing transactions it has received in the stress testing blockchain network, that is, the stress testing blockchain nodes b, c, and d can obtain these 50 stress testing transactions . Similarly, the stress testing blockchain node b can broadcast the 40 stress testing transactions it has received in the stress testing blockchain network, that is, the stress testing blockchain nodes a, c, and d can obtain these 40 stress testing transactions. trade. The stress testing blockchain node c can broadcast the 30 stress testing transactions it has received in the stress testing blockchain network, that is, the stress testing blockchain nodes a, b, and d can obtain these 30 stress testing transactions. The stress testing blockchain node d can broadcast the 20 stress testing transactions it has received in the stress testing blockchain network, that is, the stress testing blockchain nodes a, b, and c can obtain these 20 stress testing transactions. Through the above broadcast process, the stress testing blockchain nodes a~d can obtain 140 identical stress testing transactions, and then perform consensus, execution, and chain operations for these 140 stress testing transactions.

In another case, any business blockchain node in the business blockchain network 32 can forward all business blockchain nodes in the business blockchain network 32 to the stress testing blockchain network 33 from the business end 31 Received stress test transaction. Among them, after each business blockchain node in the business blockchain network 32 receives the pressure measurement transaction from the service terminal 31, it can broadcast the received pressure measurement transaction in the business blockchain network 32, so that the business The stress test transactions received by all the business blockchain nodes in the blockchain network 32 can be synchronously received, that is, each business blockchain node can obtain all the business blockchain nodes received from the business end. Stress test transactions, and then forward these stress test transactions to the business blockchain network.

Alternatively, a forwarding node for forwarding pressure measurement transactions can be configured in the business blockchain network 32, then when a certain business blockchain node in the business blockchain network 32 is a forwarding node, the business area The blockchain node forwards the stress testing transaction to the stress testing blockchain network 33 . Each business blockchain node in the business blockchain network 32 can send the stress test transaction received from the business end to the forwarding node, and the forwarding node uniformly transmits the stress test transaction received by all business blockchain nodes from the business end. The transaction is forwarded to the stress testing blockchain network 33 . For example, the forwarding node can establish a connection with a certain stress testing blockchain node in the stress testing blockchain network 33, so as to forward all stress testing transactions to the stress testing blockchain node, so that the stress testing blockchain The node broadcasts the stress testing transaction from the forwarding node in the stress testing blockchain network 33, so that all stress testing blockchain nodes in the stress testing blockchain network 33 can obtain the stress testing transaction from the forwarding node, and then conduct consensus, Execute, upload, etc. operations. For another example, the forwarding node can establish a connection with each stress testing blockchain node in the stress testing blockchain network 33, thereby forwarding all stress testing transactions to each stress testing blockchain node, so that the stress testing blockchain All stress testing blockchain nodes in the network 33 can obtain stress testing transactions from forwarding nodes, and then perform operations such as consensus, execution, and on-chain operations.

The forwarding node can be selected through negotiation among the business blockchain nodes in the business blockchain network 32 . Alternatively, a forwarding node is selected in the stage of deploying the business blockchain network 32, so that the node information of the forwarding node is written into the chain code, so that each business blockchain node can store the business area corresponding to the node information recorded in the chain code. Blockchain nodes are confirmed as forwarding nodes.

The business terminal 31 can submit the created blockchain transaction to the business blockchain node by establishing a connection with a business blockchain node in the business blockchain network 32, and the business blockchain node can be The business blockchain node 32n shown in FIG. 3 . Taking the business blockchain node 32n as an example, the connection established between the business end 31 and the business blockchain node 32n can be a long connection, so that the business blockchain node 32n executes the business transaction to generate a second transaction receipt, and from the pressure measurement After the blockchain network 33 obtains the first transaction receipt, it can generate a corresponding transaction receipt generation event, and the business end 31 can learn that the transaction receipt has been generated by monitoring the transaction receipt generation event (ie, the event monitoring mechanism), and based on the above-mentioned long-term Connect to obtain the corresponding transaction receipt (first transaction receipt or second transaction receipt). Of course, the business blockchain node 32n can also monitor the transaction receipt generation event through the above-mentioned event monitoring mechanism, and feed back the corresponding transaction receipt to the business end 31 through the above-mentioned long connection, so that the business end 31 obtains the transaction receipt. Alternatively, if the connection established between the business end 31 and the business blockchain node 32n is not a long connection or the established long connection is disconnected, the business end 31 needs to initiate an additional query transaction to query the submitted blockchain The transaction receipt corresponding to the transaction. The query transaction may be a conventional blockchain transaction, so that all blockchain nodes in the business blockchain network 32 need to acquire, agree, execute, and upload the query transaction, while the business end 31 A long-term connection can be established with a business blockchain node in the above manner, and a corresponding transaction receipt can be obtained from the business blockchain node based on the above event monitoring mechanism; or, the query transaction can be a special transaction, such as a business end 31 can only establish a long connection with the business blockchain node 32n and send the query transaction, then the query transaction will only be acquired and executed by the business blockchain node 32n, the query transaction does not need to participate in the consensus and does not need to be on the chain, or even It is acquired by other blockchain nodes, and then the service terminal 31 can acquire the corresponding transaction receipt based on the event monitoring mechanism described above.

For the first transaction receipt generated after the stress testing blockchain node in the stress testing blockchain network 33 executes the stress testing transaction, the business blockchain node in the business blockchain network 32 can also be based on the aforementioned The event monitoring mechanism obtains the second transaction receipt, which will not be repeated here. For example, a connection can be established between the business blockchain node 32n and the stress testing blockchain node 33n, so as to obtain the second transaction receipt based on the aforementioned event monitoring mechanism.

Correspondingly, after acquiring the transaction receipt, the business end 31 can identify whether the acquired transaction receipt corresponds to a stress test transaction or a business transaction according to the type identifier included in the transaction receipt. When the acquired transaction receipt contains the first type identifier, it is determined that the transaction receipt is the first transaction receipt (that is, corresponding to the stress test transaction); when the acquired transaction receipt contains the second type identifier, it is determined that the transaction receipt Receipt for the second transaction (ie, corresponding to a business transaction). further. The business end 31 can store the first transaction receipt in the stress testing database, store the second transaction receipt in the business database, and can subsequently obtain the first transaction receipt from the stress testing database to analyze and determine the stress testing for the business blockchain network 32 result.
