[0032] In order to make the purpose, technical solutions and advantages of one or more embodiments of this specification clearer, the technical solutions of one or more embodiments of this specification will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of one or more embodiments of this specification.

[0033] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.

[0034] In the prior art, blockchain can be understood as a data chain consisting of multiple blocks stored sequentially. The block header of each block contains the timestamp of the current block, the hash value of the previous block information and the hash value of the current block information, thereby realizing mutual verification between blocks and blocks, forming an unalterable blockchain. Each block can be understood as a data block (a unit for storing data). As a decentralized database, blockchain is a string of data blocks generated by using cryptographic methods to correlate with each other. Each data block contains information about a network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block. The chain formed by connecting blocks end to end is the blockchain. If the data in the block needs to be modified, the content of all blocks after this block needs to be modified, and the data backed up by all nodes in the blockchain network needs to be modified. Therefore, blockchain has the characteristics of being difficult to tamper with and delete. After the data has been saved to the blockchain, it is reliable as a method to maintain the integrity of the content.

[0035] Since the blockchain network has the characteristic that data is difficult to tamper with, various institutions have gradually begun to use the blockchain network to process related businesses. In order to ensure the smooth and controllable operation of the business, various institutions usually need to stress test the blockchain network. However, if the test data is directly used for on-chain testing, it will often interfere with the process of the blockchain network processing real business requests. Therefore, how to stress test the blockchain network and obtain more accurate stress test results without interfering with the normal business processing process of the blockchain network has become a technical problem that needs to be solved urgently.

[0036] In order to solve the defects in the prior art, this solution provides the following embodiments:

[0037] Figure 1 A schematic diagram of an application scenario of a blockchain network stress testing method provided in an embodiment of this specification.

[0038] like Figure 1As shown, the first blockchain network 102 can be a blockchain network for processing real user business data, and is also a blockchain network that needs to be stress tested in this solution; the second blockchain network 103 can be used to simulate the first blockchain network 102. When the second blockchain network 103 is used for stress testing, its configuration information and stored blockchain transaction information should be consistent with the first blockchain network 102. The business server 101 can interact with the first blockchain network 102 to process the user's business request.

[0039] Specifically, when performing a stress test, the business system at the business server 101 can be used to receive or automatically generate a stress test request carrying stress test data for simulating user business data, and the stress test request can be transmitted to the on-chain client in the business server 101, so that the on-chain client generates first blockchain transaction information according to the stress test data, and sends the first blockchain transaction information to the second blockchain network 103 used to simulate the first blockchain network 102, so that the nodes in the second blockchain network reach a consensus on the first blockchain transaction information, thereby performing a stress test on the second blockchain network 103, and then determining the stress test result of the first blockchain network 102 according to the stress test result of the second blockchain network 103. Since there is no need to send the stress test data to the first blockchain network for storage, the interference of the stress test data used in the stress test process on the data in the first blockchain network can be avoided, so as to ensure the correct processing of the real user business request by the first blockchain network.

[0040] Next, a stress testing method for a blockchain network provided in an embodiment of the specification is specifically described with reference to the accompanying drawings:

[0041] Figure 2 A flowchart of a method for stress testing a blockchain network provided in an embodiment of this specification. From a program perspective, the execution subject of the process can be a business server, or an application installed on the business server.

[0042] like Figure 2 As shown, the process may include the following steps:

[0043] Step 202: Obtain a stress test request for a first blockchain network, wherein the stress test request carries stress test data for simulating user business data; the first blockchain network is a blockchain network for processing the user business data.

[0044] In the embodiments of this specification, the first blockchain network is the blockchain network to be stress-tested in this solution, which can be used to process user business data generated by users in the process of actually handling business. Specifically, the first blockchain network can store blockchain transaction information generated based on real user business data to store business processing process and business processing results. Alternatively, the first blockchain network can also use its smart contract to process blockchain transaction information generated based on the real user business data to generate business processing results, which is not specifically limited.

[0045] In the embodiments of this specification, the type of user business data processed by the first blockchain network depends on the type of business handled by the user, and no specific limitation is made to this. For example, when the business handled by the user is the purchase or sale of digital collections, the user business data may include the identity information of the buyer or seller, the identification information of the digital collections traded, etc. Among them, digital collections may refer to the unique digital certificates generated for specific works and artworks using blockchain technology, which can realize authentic and reliable digital issuance, purchase, collection and use on the basis of protecting their digital copyrights; digital collections are a type of non-fungible token (NFT). Alternatively, when the business handled by the user is to apply for a loan product or repay a loan product, the user business data may include the user's identity information, relevant information of the loan product, etc.

[0046] In the embodiments of this specification, the stress test may include a test on the performance indicators of the first blockchain network, and the performance indicators may include: transactions per second (TPS), and / or business processing time, etc.; the transactions per second (TPS) may be the number of blockchain transaction information that can be processed by the blockchain network per second, or the number of user business requests that can be processed by the blockchain network per second; the business processing time may include: the time it takes for the blockchain network to process a blockchain transaction information, and / or the total time it takes to process all blockchain transaction information corresponding to a user business request. Among them, a user business request may correspond to one blockchain transaction information or to multiple blockchain transaction information, which is not specifically limited.

[0047] In the embodiments of this specification, the stress test request for the first blockchain network can be manually initiated by a staff member by triggering a business system in a business server (for example, a user clicks on a stress test control in the business system), or can be automatically initiated by the business system in the business server according to pre-set stress test rules, and there is no specific limitation on this.

[0048] In the embodiment of this specification, the stress test data may be virtual user business data generated by the business system in the business server to simulate real user business data, so as to achieve stress testing of the first blockchain network at any time. The information types and information formats contained in the stress test data and the user business data should generally be consistent to ensure the accuracy of the stress test results.

[0049] Step 204: In response to the stress test request, generate first blockchain transaction information according to the stress test data.

[0050] In the embodiment of the present specification, after obtaining a stress test request for the first blockchain network, first blockchain transaction information must be generated based on the stress test data. This is because the stress test for the blockchain network is a test of the blockchain network's operational capability to process blockchain transaction information.

[0051] In actual applications, the first blockchain transaction information generated based on stress test data and the blockchain transaction information generated based on real user business data contain the same information type and format to ensure the accuracy of the stress test results.

[0052] Step 206: Send the first blockchain transaction information to the second blockchain network; the configuration information and stored blockchain transaction information of the second blockchain network are consistent with those of the first blockchain network.

[0053] In the embodiments of the present specification, a second blockchain network can be deployed for the first blockchain network to be stress tested, and the second blockchain network is used to simulate the first blockchain network. Since the configuration information and transaction information of the second blockchain network are closer to the first blockchain network, the stress test results of the second blockchain network can more accurately reflect the stress test results of the first blockchain network. Therefore, this solution uses the configuration information of the first blockchain network and the stored blockchain transaction information to configure the second blockchain network, so that the configuration information and the stored blockchain transaction information of the second blockchain network are consistent with the configuration information and the stored blockchain transaction information of the first blockchain network.

[0054] In the embodiments of this specification, the configuration information consistency may include: the number of nodes in the second blockchain network is consistent with the number of nodes in the first blockchain network, the software and hardware resources of the corresponding nodes, and the blockchain configuration. For example, if the first blockchain network includes ten nodes, then the second blockchain network must be configured with ten nodes accordingly. Assuming that a node in the first blockchain network is configured with 10G of traffic and 10G of memory, the node in the second blockchain network corresponding to this node in the first blockchain network must also be configured with 10G of traffic and 10G of memory accordingly. In addition, the block size, queue length, consensus algorithm, consensus frequency, etc. of the first blockchain network and the second blockchain network must be consistent.

[0055] In actual applications, the nodes in the first blockchain network and the nodes in the second blockchain network may be prohibited from communicating with each other to ensure the isolation of data in the first blockchain network from data in the second blockchain network, which is conducive to improving the security of data in the first blockchain network.

[0056] In the embodiments of this specification, it is necessary to synchronize the data of the first blockchain network and the second blockchain network in advance so that the data in the second blockchain network is consistent with the data in the first blockchain network. Specifically, the data in the first blockchain network can be copied to the off-chain device, and then the data in the first blockchain network copied to the off-chain device is written to the second blockchain to achieve data synchronization between the first blockchain network and the second blockchain network; or, instructions can be sent to the platform for building the blockchain network to use the platform and / or the underlying blockchain capabilities to copy the data of the first blockchain network and write it to the second blockchain network to achieve data synchronization between the first blockchain network and the second blockchain network, and there is no specific limitation on this.

[0057] Step 208: Determine the stress test result for the first blockchain network based on the stress test result of the second blockchain network on the first blockchain transaction information.

[0058] In the embodiments of this specification, the stress test result of the second blockchain network can be directly used as the stress test result of the first blockchain network, or the result obtained by processing multiple stress test results of the second blockchain network (for example, calculating the average) can be used as the stress test result of the first blockchain network, without specific limitation.

[0059] Figure 2The method in the embodiment of the present invention is to build a second blockchain network that is consistent with the configuration information and stored blockchain transaction information of the first blockchain network. When it is necessary to perform stress testing on the first blockchain network used to process real user business data, the first blockchain transaction information generated by the stress test data used to simulate the real user business data can be sent to the second blockchain network for processing, so as to generate a stress test result with good accuracy for the first blockchain network based on the stress test result of the second blockchain network for the first blockchain transaction information. At the same time, since the scheme does not upload the stress test data to the first blockchain network, it is also conducive to ensuring the authenticity and accuracy of the data at the first blockchain network, so as to avoid interference with the normal business processing process of the first blockchain network.

[0060] based on Figure 2 The method in this specification also provides some specific implementation plans of the method, which are described below.

[0061] In the embodiments of the present specification, since the first blockchain network usually needs to store blockchain transaction information generated based on real user business data on the chain in real time, and the first blockchain network is only occasionally stress tested, after a period of time after a stress test on the first blockchain network, there will be certain differences between the blockchain transaction information in the first blockchain network and the blockchain transaction information in the second blockchain network.

[0062] Based on this, before sending the first blockchain transaction information to the second blockchain network, it also includes:

[0063] Determine target blockchain transaction information that the second blockchain network lacks compared to the first blockchain network, where the target blockchain transaction information is blockchain transaction information generated based on the user business data processed by the first blockchain network.

[0064] The target blockchain transaction information is stored in the second blockchain network.

[0065] In an embodiment of the present specification, the target blockchain transaction information may include blockchain transaction information generated based on user business data processed by the first blockchain network during the last and current stress tests on the first blockchain network.

[0066] In practical applications, the data stored in the blockchain network is usually linked in order from far to near by blocks containing blockchain transaction information. In addition to blockchain transaction information, the block may also include other data, such as: block birth time, block hash value, block height (number of blocks), etc.; among them, since the hash value of each block is generated according to the hash value of its previous block, the block hash value can uniquely and clearly identify a block, and any blockchain network node can independently obtain the block hash value by simply performing a hash calculation on the block header; in addition, the block height (blockheight), that is, the position of the block in the blockchain, can also be used to identify the block.

[0067] Based on this, when it is necessary to determine the target blockchain transaction information that the second blockchain network lacks compared to the first blockchain network, the corresponding block can be found in the first blockchain network by identifying the hash value or block height of the last block generated in the second blockchain network, and the blockchain transaction information of all blocks after this block in the first blockchain network can be stored in the second blockchain network.

[0068] In the embodiments of the present specification, the target blockchain transaction information that is missing from the second blockchain network compared to the first blockchain network is determined, and the target blockchain transaction information is stored in the second blockchain network; only the target blockchain transaction information that is missing from the second blockchain network compared to the first blockchain network is synchronized, which effectively reduces the amount of data processing and improves the efficiency of stress testing the first blockchain network; it is worth noting that when data synchronization processing is missing between the second blockchain network and the first blockchain network, the second blockchain network can also be rebuilt and configured before stress testing the first blockchain network to ensure that the first blockchain network and the second blockchain network are completely synchronized in terms of data, and there is no specific limitation on this.

[0069] In the embodiments of this specification, there are multiple ways to keep the blockchain transaction information stored in the second blockchain network consistent with that stored in the first blockchain network.

[0070] Implementation method 1

[0071] Considering the privacy of user data stored in the first blockchain network, it may not be convenient to directly copy the blockchain transaction information in the first blockchain network to the second blockchain network. Therefore, it is necessary to convert the blockchain transaction information generated based on real user business data stored in the first blockchain network into blockchain transaction information generated based on virtual user business data (for example, data in the form of stress test data), and then write the converted blockchain transaction information into the second blockchain network.

[0072] Based on this, before step 202: obtaining a stress test request for the first blockchain network, the following may also be included:

[0073] A first user service processing request is obtained; the first user service processing request carries the user service data.

[0074] Determine virtual user unique identification information corresponding to the real user unique identification information in the user service data.

[0075] Generate second blockchain transaction information carrying the real user's unique identification information.

[0076] The second blockchain transaction information is stored in the first blockchain network.

[0077] Generate third blockchain transaction information carrying the unique identification information of the virtual user.

[0078] The third blockchain transaction information is stored in a third blockchain network; the blockchain transaction information stored in the third blockchain network is consistent with that stored in the first blockchain network.

[0079] The determining of the target blockchain transaction information that the second blockchain network lacks compared to the first blockchain network may specifically include:

[0080] According to the block information of the third blockchain network and the block information of the second blockchain network, determine the target blockchain transaction information that the second blockchain network lacks compared to the first blockchain network from the third blockchain transaction information at the third blockchain network.

[0081] In an embodiment of the present specification, the user business data carried in the first user business processing request is the user business data generated by the real user in the actual business processing process, and the user business data may include a unique identifier of the real user, which is usually information at the business server used to uniquely identify any real user, for example, the account information that the real user needs to use in the business processing process, or the user identity UID (User Identification) that the real user needs to use in the business processing process.

[0082] In the embodiments of this specification, the unique identification information of a virtual user can be used to uniquely identify a virtual user for stress testing. A unique identification information of a virtual user can be obtained by transforming a unique identification information of a real user according to a preset rule, that is, the unique identification information of the real user and the unique identification information of the virtual user can correspond one to one. In actual application, the user will not use the unique identification information of the virtual user in the actual business process, and the unique identification information of the virtual user is only used in the stress testing process.

[0083] In the embodiment of the present specification, in the process of processing real user business requests, the second blockchain transaction information and the third blockchain transaction information can be generated based on the real user business data. The difference is that the user unique identification information in the second blockchain transaction information is the real user unique identification, while the user unique identification information in the third blockchain transaction information is the virtual user unique identification information.

[0084] In the embodiments of this specification, the block information may include: block birth time, block hash value, block height (number of blocks), etc. Since the principle of realizing data synchronization between blockchain networks based on block information has been explained in the previous embodiments, and the target blockchain transaction information that the second blockchain network lacks compared to the first blockchain network can be determined from the third blockchain transaction information at the third blockchain network based on block information based on relevant principles, and thus it will not be described in detail.

[0085] In the embodiments of this specification, the third blockchain network can communicate directly with the nodes in the second blockchain network to achieve cross-chain transmission, so that the data of each node in the second blockchain network can be directly copied from each node in the third blockchain network, which is convenient and fast. It is worth noting that, since the blockchain transaction information stored in the second blockchain network is obtained from the third blockchain network, there is no need for the nodes in the first blockchain network and the nodes in the second blockchain network to communicate with each other to ensure that the data in the first blockchain network is isolated from the data in the second blockchain network, thereby ensuring the security of the data in the first blockchain network.

[0086] In the embodiment of this specification, the blockchain transaction information carrying the unique identification information of the virtual user corresponding to the unique identification information of the real user is stored by using the third blockchain network, and then the third blockchain network is used to synchronize data with the second blockchain network to achieve stress testing. In this embodiment, since the data at the third blockchain network and the second blockchain network are both virtual user business data, rather than real user business data, the real user business data is only stored in the first blockchain network, which is conducive to avoiding the leakage of the real user business data, so as to ensure the privacy and security of the real user business data during the stress test.

[0087] In practical applications, since blockchain transaction information usually needs to include blockchain account information to indicate the initiator and recipient of the blockchain transaction information, based on this, before generating the third blockchain transaction information carrying the unique identification information of the virtual user, it may also include:

[0088] Determine blockchain account information corresponding to the virtual user unique identification information at the second blockchain network.

[0089] The generating of the third blockchain transaction information carrying the unique identification information of the virtual user specifically includes:

[0090] Generate third blockchain transaction information that carries the unique identification information of the virtual user and the blockchain account information.

[0091] Data synchronization is performed on the third blockchain network and the second blockchain network, and the target blockchain transaction information is stored in the second blockchain network.

[0092] In the embodiments of the present specification, corresponding blockchain account data can be generated according to the unique identification information of the virtual user, so that the generated blockchain account data can be used as the blockchain account in the second blockchain network, so that the generated blockchain account data can be added to the third blockchain transaction information carrying the unique identification information of the virtual user, so as to serve as the blockchain account information of the initiator or recipient of the third blockchain transaction information.

[0093] In practical applications, since the second blockchain network is a real blockchain network, the user public key information corresponding to the virtual user unique identification information can also be used to generate transaction information for registering a blockchain account at the second blockchain network, so as to obtain the blockchain account at the second blockchain network corresponding to the virtual user unique identification information through the real account registration process. It is worth noting that the blockchain account at the second blockchain network corresponding to the virtual user unique identification information can be the same as or different from the blockchain account at the first blockchain network corresponding to the real user unique identification information of the virtual user unique identification information, and there is no specific limitation on this.

[0094] In the embodiments of this specification, since the second blockchain network needs to synchronize data with the third blockchain network, the form of blockchain transaction information stored in the second blockchain network and the third blockchain network should be consistent. Therefore, when the second blockchain network needs to be used to process the first blockchain network information for stress testing, the form of the first blockchain network information and the third blockchain transaction information stored in the third blockchain network should also be consistent.

[0095] Based on this, generating the first blockchain transaction information according to the stress test data may specifically include:

[0096] Determine the target virtual user unique identification information in the stress test data.

[0097] Determine the target blockchain account information corresponding to the target virtual user unique identification information at the second blockchain network.

[0098] Generate first blockchain transaction information carrying the target virtual user unique identification information and the target blockchain account information.

[0099] In the embodiments of this specification, the target virtual user unique identification information can be used to uniquely identify the test user to which the stress test data belongs, and the target virtual user unique identification information can be the virtual user unique identification information mentioned in the previous embodiments. And the target blockchain account information can be used to represent the address of the blockchain account of the test user at the second blockchain network. Based on this, a first blockchain transaction information carrying the target virtual user unique identification information and the target blockchain account information can be generated to ensure that the first blockchain network information is consistent with the third blockchain transaction information stored at the third blockchain network, and then the first blockchain network information is also consistent with the blockchain transaction information stored at the second blockchain network, so as to ensure that the second blockchain network can be used to process the first blockchain network information to obtain the stress test process.

[0100] Implementation method 2

[0101] Generally speaking, the higher the degree of simulation of the second blockchain network on the first blockchain network, the more accurately the stress test results on the second blockchain network can reflect the actual operating performance of the first blockchain network. Therefore, considering the cost and accuracy of the stress test, the blockchain transaction information in the first blockchain network can also be directly copied to the second blockchain network for stress testing.

[0102] Based on this, before obtaining the stress test request for the first blockchain network, the following may also be included:

[0103] A second user service processing request is obtained; the second user service processing request carries the user service data.

[0104] Generate fourth blockchain transaction information that carries the real user unique identification information in the user business data.

[0105] The fourth blockchain transaction information is stored in the first blockchain network.

[0106] The determining of the target blockchain transaction information that the second blockchain network lacks compared to the first blockchain network may specifically include:

[0107] According to the block information of the first blockchain network and the block information of the second blockchain network, determine the target blockchain transaction information that the second blockchain network lacks compared to the first blockchain network from the fourth blockchain transaction information at the first blockchain network.

[0108] Data synchronization is performed on the first blockchain network and the second blockchain network, and the target blockchain transaction information is stored in the second blockchain network.

[0109] In the embodiment of this specification, the first blockchain network may be a blockchain network for processing real user business data. The second user business request may be a user business request generated by a real user in the process of actually processing a business. The real user unique identification information may be used to represent the identity information of the real user in the business server. Thus, the fourth blockchain transaction information may be generated based on the real user business data and stored in the first blockchain network, so that the fourth blockchain transaction information may be processed using the first blockchain network, thereby realizing the processing of the real business.

[0110] In the embodiments of this specification, the blockchain transaction information stored in the first blockchain network can be directly copied to the second blockchain network to achieve data synchronization. Since there is no need to deploy a third blockchain network, it is beneficial to reduce the cost of stress testing. In addition, since the blockchain account and user unique identification information carried by the blockchain transaction information stored in the second blockchain network are the blockchain account and real user unique identification information of the real user in the first blockchain network, respectively, the blockchain transaction information of the second blockchain network is highly consistent with that of the first blockchain network, which is beneficial to ensure the accuracy of the stress test on the first blockchain network.

[0111] In the embodiments of the present specification, since the data stored in the second blockchain network is obtained by copying the data in the first blockchain network, the user unique identifier in the blockchain transaction information in the second blockchain network is the real user unique identifier. However, since the user unique identifier contained in the stress test data is the target virtual user unique identifier information, if the stress test is performed directly using the target virtual user unique identifier information, there will be no blockchain transaction information generated based on historical user business data associated with it in the second blockchain network, thereby affecting the accuracy of the stress test results.

[0112] Based on this, generating the first blockchain transaction information according to the stress test data may specifically include:

[0113] Determine the target real user unique identification information corresponding to the target virtual user unique identification information in the stress test data.

[0114] Generate first blockchain transaction information carrying the unique identification information of the target real user.

[0115] In the embodiments of the present specification, since the blockchain transaction information stored in the second blockchain network carries the unique identification information of the real user, but the stress test data carries the unique identification information of the target virtual user, it is necessary to carry the real user unique identification information corresponding to the unique identification information of the target virtual user in the first blockchain transaction information to ensure the consistency of the blockchain transaction information in the first blockchain network and the blockchain transaction information in the second blockchain network, thereby facilitating the use of the second blockchain network to perform stress testing based on the first blockchain transaction information, which is beneficial to improving the accuracy of the stress test results.

[0116] In actual applications, when the user to whom the real user unique identification information corresponding to the target virtual user unique identification information belongs has performed business before, the first blockchain network and the second blockchain network usually store the user's historical business data, so that stress testing can be performed using old users who have performed business, which is conducive to improving the accuracy of stress test results. When the user to whom the real user unique identification information corresponding to the target virtual user unique identification information belongs has not performed business, it is equivalent to performing stress testing using new users who have not performed business, which is conducive to improving the flexibility of stress testing.

[0117] In the embodiment of the present specification, since the first blockchain network is consistent with the second blockchain network, the stress test result for the first blockchain network can be determined according to the stress test result of the second blockchain network.

[0118] Specifically, step 208: determining the stress test result for the first blockchain network according to the stress test result of the second blockchain network on the first blockchain transaction information may include:

[0119] Obtain performance indicator data of the second blockchain network during the process of processing the first blockchain transaction information.

[0120] Determine a stress test result for the first blockchain network based on the performance indicator data.

[0121] In the embodiments of this specification, the performance indicators may include: transactions per second (TPS) and / or business processing time, where the transactions per second refers to the number of blockchain transaction information processed by the blockchain network per second; the business processing time may include: the time it takes for the blockchain to complete processing of one blockchain transaction information, and / or the total time it takes to complete processing of all blockchain transaction information corresponding to a business.

[0122] In actual applications, if the performance indicators of the first blockchain network and the second blockchain network are the same indicator data, the performance indicator data of the second blockchain network can be directly used as the stress test result of the first blockchain network, or the performance indicator data of the second blockchain network can be calculated (for example, the performance indicator data of multiple time periods of the second blockchain network is averaged) to obtain the data as the stress test result of the first blockchain network, without specific limitation.

[0123] If the performance indicators of the first blockchain network and the second blockchain network are different indicator data, it is necessary to perform calculations on the performance indicator data of the second blockchain network. For example, the performance indicator of the first blockchain network is the number of transactions per second (TPS), and the performance indicator data of the second blockchain network is the time it takes for the blockchain to complete a blockchain transaction information. Then the stress test result of the first blockchain network is the inverse of the time consumption.

[0124] In the embodiments of this specification, the business server can usually obtain real business processing requests and stress test requests, so it is necessary to parse the obtained user business requests to determine whether the currently obtained user business processing requests belong to stress test requests.

[0125] Based on this, obtaining a stress test request for the first blockchain network specifically includes:

[0126] Obtain a third-party user service processing request.

[0127] It is determined whether the third user service processing request carries stress test identification information, and a determination result is obtained.

[0128] If the judgment result indicates that the third user service processing request carries stress test identification information, the third user service processing request is determined to be a stress test request.

[0129] In the embodiments of this specification, the stress test identification information can be implemented by user unique identification information and / or data type identification information. The user unique identification information can be virtual user unique identification information or user unique identification information. The data type identification information can be used to identify the type of data carried by the third user service processing request as stress test data or real user service data.

[0130] Specifically, if the third user service processing request carries virtual user unique identification information, it can be indicated that it carries stress test identification information, so that the third user service processing request can be determined as a stress test request. If the third user service processing request carries real user unique identification information, it can be prohibited to determine the third user service processing request as a stress test request.

[0131] Alternatively, if the third user service processing request carries data type identification information for identifying that the data type is stress test data, it can be indicated that it carries stress test identification information, so that the third user service processing request can be determined as a stress test request. Otherwise, it should be prohibited to determine the third user service processing request as a stress test request, which is convenient and quick.

[0132] Figure 3 The embodiments of this specification provide corresponding to Figure 2 A swimlane flow diagram of the stress testing method for blockchain networks in . Figure 3 As shown, the stress testing process of the blockchain network may involve execution entities such as the business server, the first blockchain network, the second blockchain network, and the third blockchain network.

[0133] During the real user business data processing stage, the business server first obtains a user business processing request carrying real user business data, then generates a second blockchain transaction information carrying the real user unique identification information in the real user business data, and sends the second blockchain transaction information to the first blockchain network. The first blockchain network can store the obtained second blockchain transaction information.

[0134] At the same time, considering the privacy of user data stored in the first blockchain network, it may not be convenient to directly copy the blockchain transaction information in the first blockchain network to the second blockchain network. Based on this, it is also necessary to determine the virtual user unique identification information corresponding to the real user unique identification information in the real user business data after the business server obtains the user business processing request carrying the real user business data, and then generate the third blockchain transaction information carrying the virtual user unique identification information, and send the third blockchain transaction information to the third blockchain network, and the third blockchain network stores the obtained third blockchain transaction information. It can be seen that the blockchain transaction information stored in the third blockchain network is consistent with that in the first blockchain network.

[0135] During the stress test phase, the business server can obtain a stress test request carrying stress test data. Subsequently, data synchronization can be performed directly on the first blockchain network and the second blockchain network, by sending the target blockchain transaction information that the first blockchain network has more than the second blockchain network to the second blockchain network to ensure the consistency of the blockchain transaction information stored in the first blockchain network and the second blockchain network. Then, the target real user unique identification information corresponding to the target virtual user unique identification information carried in the stress test data can be determined to generate the first blockchain transaction information carrying the target real user unique identification information, and send the first blockchain transaction information to the second blockchain network. The second blockchain network can then obtain the first blockchain transaction information and process the first blockchain transaction information so that the business server can determine the stress test results for the first blockchain network based on the stress test results of the second blockchain network for the first blockchain transaction information.

[0136] During the stress test phase, when data synchronization cannot be performed directly on the first blockchain network and the second blockchain network, since the blockchain transaction information stored in the third blockchain network is consistent with that in the first blockchain network, the target blockchain transaction information that the third blockchain network has more than the second blockchain network can be sent to the second blockchain network to ensure the consistency of the blockchain transaction information stored in the first blockchain network and the second blockchain network. Then, the business server can also determine the target virtual user unique identification information carried in the stress test data to generate the first blockchain transaction information carrying the target virtual user unique identification information, and send the first blockchain transaction information to the second blockchain network. The second blockchain network obtains the first blockchain transaction information and processes the first blockchain transaction information so that the business server can determine the stress test results for the first blockchain network based on the stress test results of the second blockchain network for the first blockchain transaction information.

[0192] Each embodiment in this specification is described in a progressive manner. The same or similar parts between the embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments. Figure 5 As for the device shown, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0193] In the 1990s, improvements to a technology could be clearly distinguished as hardware improvements (for example, improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the method flow). However, with the development of technology, many improvements to the method flow today can be regarded as direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. Designers can "integrate" a digital system on a PLD by programming it themselves, without having to ask a chip manufacturer to design and produce a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented with "logic compiler" software, which is similar to the software compiler used when developing and writing programs. The original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL). There is not only one kind of HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also be aware that it is easy to obtain a hardware circuit that implements the logical method flow by simply performing some logic programming on the method flow using the above-mentioned hardware description languages ​​and programming it into an integrated circuit.

[0194] The controller can be implemented in any appropriate manner. For example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing a computer-readable program code (such as software or firmware) that can be executed by the (micro)processor, a logic gate, a switch, an application-specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of controllers include, but are not limited to, the following microcontrollers: ARC625D, AtmelAT91SAM, MicrochipPIC18F26K20, and SiliconeLabsC8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that in addition to implementing the controller in a purely computer-readable program code manner, the controller can be implemented in the form of a logic gate, a switch, an application-specific integrated circuit, a programmable logic controller, and an embedded microcontroller by logically programming the method steps. Therefore, this controller can be considered as a hardware component, and the devices included therein for implementing various functions can also be considered as structures within the hardware component. Or even, the devices for implementing various functions can be considered as both software modules for implementing the method and structures within the hardware component.
