[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0055] With the development of blockchain technology, the performance of blockchain systems continues to improve. However, single-node pressure generation faces a single-point pressure bottleneck, and its efficiency cannot be further improved.

[0056] In view of this, the present invention provides a performance testing method suitable for multi-node blockchain systems, which can achieve horizontal scaling of stress testing capacity, simultaneously applying stress to multiple blockchain nodes, thereby improving performance testing efficiency. See also Figure 1 The diagram illustrates a specific embodiment of the performance testing method for multi-node blockchain systems provided by the present invention. The method is applied to a blockchain system with a blockchain network comprising N sequentially connected blockchain nodes, where N is a natural number greater than 2. In this embodiment, the method includes steps S01, S02, S03, S04, and S05.

[0057] Step S01: Generate transaction data based on the data to be tested;

[0058] Step S02: Send the transaction data to the first blockchain node;

[0059] Step S03: Receive transaction feedback returned by the Nth blockchain node;

[0060] Step S04: Obtain test data during the process from "sending the transaction data to the first blockchain node" to "receiving the transaction feedback returned by the Nth blockchain node";

[0061] Step S05: Obtain the test results based on the test data.

[0062] The test data refers to the test data required to verify compliance with usage standards before the blockchain system is officially used, or data that can be obtained from the test data to confirm compliance with usage standards. This test data or data will affect the use of the blockchain system. For example, the test data includes the first time point t. send Second time point t recv Number of transaction data per node n recv Total transaction time t for a single node all Total number of transactions nconf and total transaction time T ALL Transaction storage volume n send .

[0063] Since the N blockchain nodes in the blockchain network have an ordered arrangement, and the first blockchain node is the first in that order, the transaction data is transmitted sequentially to each of the blockchain nodes in the blockchain network according to the ordered arrangement. Therefore, transaction data sent at different times can be executed simultaneously on multiple blockchain nodes, thereby improving the efficiency of blockchain system performance testing. For example, after the transaction data is sent to the first blockchain node, the same transaction data will be executed sequentially on the second blockchain node, the third blockchain node, and so on up to the Nth blockchain node. If the transaction data is continuously sent to the blockchain network, then multiple blockchain nodes will be processing the transaction data simultaneously. For example, the first transaction data sent is called the first transaction data, the second transaction data sent is called the second transaction data, and so on up to the Nth transaction data. Then, the first transaction data, the second transaction data, and so on up to the Nth transaction data are sent to the blockchain network sequentially. After the third transaction data is sent to the blockchain network, the first blockchain node executes and / or processes the third transaction data, the second blockchain node executes and / or processes the second transaction data, and the third blockchain node executes and / or processes the first transaction data. The first, second, and third blockchain nodes can simultaneously execute or process transaction data, thus achieving horizontal scaling of the stress-generating capacity. Simultaneously applying stress to multiple blockchain nodes can improve performance testing efficiency.

[0064] In one embodiment, step S02, which involves sending the transaction data to the first blockchain node, includes steps S021 and S022.

[0065] Step S021: Determine the target transaction data from the transaction data according to the voltage setting parameters;

[0066] Step S022: Continuously send the target transaction data to the first blockchain node until the target transaction data is sent completely or the preset transmission duration is exceeded.

[0067] The pressure setting parameters include pressure duration and transaction data volume. Within the transaction data, target transaction data is determined based on the pressure setting parameters. The target transaction data's data volume and sustained pressure duration are identical to the pressure setting parameters. Determining the target transaction data based on the pressure setting parameters ensures a sufficient volume of transaction data and sufficient pressure duration, resulting in more test data and more accurate test results.

[0068] In one embodiment, as shown in the appendix Figure 2 As shown, step S01, before generating transaction data based on the test data, includes:

[0069] Step S1: Determine test cases based on test setting parameters and test process; wherein, the test setting parameters include pressure release time point, simulated concurrency, transaction data quantity, transaction data sending speed, transaction execution logic, transaction data storage volume, and nodes receiving pressure;

[0070] Step S2: Determine the testing tools based on the test cases and the multi-node blockchain system;

[0071] Step S3: Connect the testing tool to the multi-node blockchain system.

[0072] Test cases are the transaction data, parameter settings, and execution flow required during a performance test of a blockchain system. Key data in test cases includes the pressure release time, simulated concurrency, number of transaction data, transaction data transmission speed, transaction execution logic, transaction data storage volume, and the node receiving the pressure. The testing tool is a device used to test a blockchain system using test cases. For example, the testing tool is a performance testing device suitable for multi-node blockchain systems, including a pressure release unit, a receiving unit, an acquisition unit, an analysis unit, and a control unit. The pressure release unit sends the transaction data to the first blockchain node; the receiving unit receives transaction feedback returned by the Nth blockchain node; the acquisition unit acquires test data during the process from "sending the transaction data to the first blockchain node" to "receiving transaction feedback returned by the Nth blockchain node"; the analysis unit obtains test results based on the test data; and the control unit, connected to the sending unit, the receiving unit, and the analysis unit, controls the operation of these units.

[0073] The testing tool is connected to the multi-node blockchain system, and can send transaction data to the multi-node blockchain system, receive information fed back from the blockchain system, and obtain the test data required in the process of sending transaction data to the multi-node blockchain system. It can also analyze the test data to obtain test results, and evaluate the performance, functionality, and transaction efficiency of the multi-node blockchain system based on the test results.

[0074] In one embodiment, step S3, connecting the testing tool to the multi-node blockchain system, includes steps S31 and S32.

[0075] Step S31: Build multiple blockchain networks in the blockchain system. The number of blockchain nodes in the multiple blockchain networks is different, and the number of blockchain nodes in the multiple blockchain networks decreases or increases in a gradient.

[0076] Blockchain systems require building blockchain networks with varying numbers of nodes to meet specific needs. This gradient in the number of nodes allows for the assessment of how the system's performance changes as the number of nodes increases. Examples include networks with 4, 8, or 16 nodes. Alternatively, a blockchain network with a fixed number of nodes can be built, allowing for testing of the overall system performance using different test cases.

[0077] Step S32: Connect the testing tool to the blockchain network.

[0078] The testing tool is connected to the blockchain network through methods such as RPC (Remote Procedure Call), HTTP (Hypertext Transfer Protocol), and SDK (software development kit).

[0079] In one embodiment, the test data includes a first time point t send Second time point t recv Number of transaction data per node n recv Total transaction time t for a single node all Total number of transactions n conf and total transaction time T ALL Transaction storage volume n send ;

[0080] Among them, the first time point t send This refers to the time point at which the transaction data is sent to the first blockchain node each time.

[0081] Second time point t recv This refers to the time point at which the transaction feedback is received from the Nth blockchain node.

[0082] Total transaction time t for a single node all The time taken for a single blockchain node to send the first transaction data to the last transaction data and receive the response;

[0083] Total number of transactions n conf The total number of transactions across all blockchain networks;

[0084] Transaction storage volume n send This refers to the amount of transaction data that can be stored across all blockchain networks after a transaction occurs.

[0085] The aforementioned test data can be recorded by the testing tool during the transaction process and directly obtained from the testing tool's storage medium.

[0086] In one embodiment, test results can be obtained by calculating, analyzing, and creating visualizations from the test data obtained from the test tool's storage medium. Step S05, obtaining test results based on the test data, includes:

[0087] Step S051: Based on the first time point t send Second time point t recv Determine the response time TD (Transaction Delay), TD1, TD2...TD n The response time for sending the transaction data to the blockchain network n times is identified by TD1, TD2...TD. n Determine the average transaction delay (ATD) and maximum transaction delay (MTD) for n transactions;

[0088] The formulas for calculating the average time taken (ATD) and the maximum time taken (MTD) are as follows:

[0089] Average time ATD = avg(TD1, TD2, ... TD) n );

[0090] Maximum execution time MTD = max(TD1, TD2, ... TD) n ).

[0091] Step S0512: Based on the number of transaction data n for a single node recv The total transaction time t of the single node all Determine the number of transactions received per second (RTPS) by the blockchain nodes;

[0092] The formula for calculating the RTPS (Transactions Per Second) of a blockchain node is as follows:

[0093] Number of transactions received by a blockchain node per second

[0094] Step S0513: Based on the total number of transactions n conf and the total transaction time T ALL Determine the number of confirmed transactions per second (CTPS) of the blockchain system;

[0095] The formula for calculating the number of transactions confirmed per second (CTPS) is as follows:

[0096] Number of transactions confirmed per second

[0097] Step S0514: Based on the total number of transactions n conf and transaction storage volume n send Determine the Transaction Success Rate (TSR);

[0098] The formula for calculating the transaction success rate (TSR) is as follows:

[0099] Transaction success rate

[0100] Step S052: Determine the test results based on the average time consumption, the maximum time consumption, the number of transactions received by the blockchain node per second, the number of transactions confirmed per second, and the transaction success rate.

[0101] The order of steps S0511 to S0514 above can be reversed. The performance of the blockchain system is evaluated using data such as the average time consumption, the maximum time consumption, the number of transactions received by the blockchain node per second, the number of transactions confirmed per second, and the transaction success rate, as test results. For example, a comparison value for average time consumption, a comparison value for maximum time consumption, a comparison value for the number of transactions received by the blockchain node per second, a comparison value for the number of transactions confirmed per second, and a comparison value for the transaction success rate can be preset. The average time consumption is compared with the average time consumption comparison value, the maximum time consumption is compared with the maximum time consumption comparison value, the number of transactions received by the blockchain node per second is compared with the number of transactions received by the blockchain node per second, the number of transactions confirmed per second is compared with the number of transactions confirmed per second, and the transaction success rate is compared with the transaction success rate comparison value to obtain comparison results, which are then used as test results.

[0102] The average processing time, the maximum processing time, the number of transactions received by the blockchain node per second, the number of transactions confirmed per second, and the transaction success rate can be visualized into graphs to display the test results. These visualizations can be line charts, bar charts, pie charts, etc.
