[0065] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0066] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0067] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0068] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0069] In the embodiments provided by this invention, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean that B is determined solely based on A; B can also be determined based on A and / or other information.

[0070] For ease of understanding, the following describes some aspects of the embodiments of the present invention:

[0071] like Figure 1 As shown, an embodiment of the present invention provides a method for matching computing power nodes, wherein the method is executed by a first network device in a blockchain network, and the method includes:

[0072] Step S10: Obtain the computing requirements sent by the first device; wherein, the computing requirements include data resource requirements and first computing node requirements;

[0073] It should be noted that, as Figure 2 As shown, a matching system for computing power nodes corresponding to a matching method for computing power nodes is now provided. In step 201, the first device sends a data request registration to the blockchain network. For example... Figure 3 As shown, in step 301, the first device publishes its computing needs on the blockchain network. Figure 4 As shown, in step 401, the first device publishes its computing request on the blockchain network. The computing management smart contract is the first network device. The first device, as the computing requester, can view data resources on the blockchain network and include information about selected data resources in its data resource request. It then sends its computing request, including the data resource request, to the first network device. Furthermore, the first device also sends its specific requirements for computing power nodes (i.e., the first computing power requirement) to the blockchain network.

[0074] Step S20: Based on the data resource requirement, present the data resource request to the second device; wherein, the second device is a device capable of providing the data resource requested by the data resource requirement.

[0075] It should be noted that the second device, which is the data provider to which the data resource requested by the first device belongs, is matched according to the data resource requirements. It has abundant data resources and publishes the metadata of its data resources on the blockchain network, which not only enables the first device to view, select and use the data, but also ensures the security of the data.

[0076] Step S30: Obtain the approval confirmation information sent by the second device according to the data resource application; wherein, the approval confirmation information includes the second computing node requirement corresponding to the data resource requirement;

[0077] It should be noted that, as Figure 2 As shown, in step 202, the second device sends a data approval request registration to the blockchain network. Figure 3 As shown, in step 302, the second device sends a data usage approval request to the blockchain network. Figure 5As shown, in step 501, the second device sends a data request for approval to the blockchain network. The second device views the data resource request on the first network device. If it agrees to use it, the approval is granted, and the approval confirmation information is sent to the first network device. The approval confirmation information includes the specific requirements for the computing power node (i.e., the requirements for the second computing power node).

[0078] Step S40: Based on the computing power information of multiple computing power nodes registered on the blockchain network, determine a target computing power node among the multiple computing power nodes to provide computing for the first device; wherein, the computing power information of the target computing power node matches the requirements of the first computing power node and the requirements of the second computing power node.

[0079] It should be noted that, as Figure 2 As shown, in step 203, the node is registered. Figure 3 In step 303, the computing power node sends a node registration message to the blockchain network. When a computing power node is idle, it can register on the blockchain network, thereby registering itself with the blockchain network. Figure 3 In step 304, the blockchain network performs computing node matching. After receiving the first computing power node requirement sent by the first device and the second computing power node requirement sent by the second device, the blockchain network performs node matching among multiple registered computing power nodes to determine the target computing power node whose computing power information matches the first and second computing power node requirements. These multiple computing power nodes possess abundant idle trusted computing resources and can provide trusted computing services. The blockchain network supports decentralized governance of these multiple computing power nodes, enabling computing node registration, querying, and intelligent matching functions. Furthermore, the computing management smart contract on the blockchain network (i.e., the first network device) automatically matches the most suitable trusted computing node (i.e., the target computing power node) based on the needs of both the supply and demand parties (i.e., the first and second devices). In this embodiment of the invention, during the data resource registration stage, the second device only registers the metadata of the data, while the original data remains stored locally on the second device, thus ensuring the privacy of the original data. During the computing power node matching stage, a computing power node selection mechanism that meets the needs of both the supply and demand sides is proposed to avoid the risk of node unavailability caused by simple matching strategies and ensure the high availability of trusted computing.

[0080] In this embodiment, after obtaining the computing requirements of the first device, a data resource application is presented to a second device capable of providing the data resources requested in the computing requirements. After the second device approves and confirms the application, the approval confirmation information sent by the second device is obtained. Based on the computing requirements and the approval confirmation information, and considering the specific needs of both the supply and demand sides, a target computing power node is matched for the first device from among multiple registered computing power nodes. By utilizing a node matching strategy and employing a reliable method, a computing power node that meets the requirements is matched, ensuring data security and high availability of computing.

[0081] Optionally, the method, wherein step S20 includes:

[0082] Obtain the first data resource identity identifier requested by the first device based on the data resource requirements;

[0083] The data resource identity is matched against a second data resource identity in at least one stored data resource; wherein the second data resource identity is a unique identity of the at least one data resource among a plurality of third devices registered on the blockchain network.

[0084] If the first data resource identity identifier matches the second data resource identity identifier of the target data resource among the at least one data resource, the data resource application is displayed to the second device among the plurality of third devices corresponding to the target data resource.

[0085] In this embodiment, Figure 4 In step 401, the computational requirements include data requirements, i.e., the data resource requirements, where ID is the identity identifier of the first data resource. Figure 2 In step 204, the second device registers its data with the blockchain network. Figure 3 In step 305, the second device registers data on the blockchain network. For example... Figure 6 As shown, in step 601, the second device sends a data registration to the blockchain network. The data registration includes an ID; that is, when the third device registers with the blockchain network, it sends the second data resource identity identifier as the unique identifier of the data resource. The third device to which the data resource belongs, corresponding to the second data resource identity identifier that matches the first data resource identity identifier, is designated as the second device. For ease of demonstration, Figure 2 , Figure 3 and Figure 6 The diagram only shows the data registration (i.e., registration) process of the second device that matches the first device. In the actual steps, the third device, which includes the second device, also performs the data registration (i.e. registration) process on the blockchain network.

[0086] Optionally, the method, wherein step S40 includes:

[0087] Based on the first computing power node requirements, the second computing power node requirements, and the computing power information, at least one first computing power node among the plurality of computing power nodes whose computing power information meets both the first computing power node requirements and the second computing power node requirements is obtained;

[0088] Based on the first computing power node requirements, the second computing power node requirements, and the computing power information, each first computing power node is scored to obtain the computing power node score corresponding to each first computing power node.

[0089] The first computing power node with the highest computing power node score is selected as the target computing power node.

[0090] In this embodiment, such as Figure 6 As shown, in step 602, the computing power node registers (i.e., registers) with the node management smart contract in the blockchain network and sends the computing power information. The node management smart contract is a third-party network device. The computing power information includes the node's unique identifier (ID), security level (Sec), trusted architecture (Arc), supported algorithm set (Algo), CPU utilization, memory utilization (Mem), service address (Host), and data encryption public key (Pubkey). Furthermore, the computing power node periodically reports heartbeats and resource utilization to the blockchain network. On the blockchain network, the computing power information also includes two metrics: online rate (Online) and trusted computing success rate (Success). The security level is divided into three levels: level 1 if the information system where the computing node is located fails the Information Security Protection Standard 2.0 test, level 2 if it passes the test, and level 3 if it passes the standard 3.0 or above. If the computing node supports the security technology Intel SGX (SoftwareGuard Extensions), it is set to SGX; if it supports the security technology Arm Trustzone, it is set to Trustzone; if it supports Hygon CSV (China Secure Virtualization), it is set to CSV. The supported algorithm set is specified, for example, if the computing node supports both Logistic Regression and eXtreme Gradient Boosting (XGBoost), it is set to {LogisticRegression, Xgboost}. The online rate is the proportion of heartbeats reported by the computing node within a week, i.e., Online = Actual Heartbeats / Theoretical Maximum Heartbeats. The CPU utilization and memory utilization (Mem) are updated within a preset period.

[0091] The computing power node score is calculated based on the first computing power node requirement sent by the first device, the second computing power node requirement sent by the second device, and the computing power information registered during the registration of the computing power node. The computing power node with the highest score among the plurality of computing power nodes is selected as the target computing power node.

[0092] Optionally, the method, wherein obtaining at least one first computing power node whose computing power information meets both the first computing power node requirements and the second computing power node requirements based on the first computing power node requirements, the second computing power node requirements, and the computing power information, includes:

[0093] Based on the comparison between the requirements of the first computing power node and the computing power information of the plurality of computing power nodes, at least one second computing power node that meets the requirements of the first computing power node is obtained.

[0094] Based on the comparison between the requirements of the second computing power node and the computing power information of the at least one second computing power node, at least one first computing power node that meets the requirements of the second computing power node is obtained.

[0095] In this embodiment, such as Figure 4 As shown, in step 401, the computational requirements also include computational node requirements (i.e., the first computational power requirement). The first computational power requirement includes: Sec_r, security level, i.e., the second computational node's Sec >= Sec_r; Arc_r, trusted architecture, i.e., the second computational node's Arc = Arc_r; Algo_r, the algorithm used in this computation, i.e., the second computational node's Algo algorithm set must include Algo_r; CPU_r, CPU utilization, i.e., the second computational node's CPU <= CPU_r; Mem_r, memory utilization, i.e., the second computational node's Mem <= Mem_r; Online_r, online rate, i.e., the second computational node's Online >= Online_r; Success_r, computation success rate, i.e., the second computational node's Success >= Success_r. Among these, Sec_r, Arc_r, and Algo_r are static indicators, while CPU_r, Mem_r, Online_r, and Success_r are dynamic indicators. The second computing node is selected from the plurality of computing nodes based on the requirements of the first computing node. For example... Figure 5As shown, in step 501, the data application approval (i.e., the approval confirmation information) also includes computing node requirements (i.e., the second computing power node requirements). The second computing power node requirements include: CPU_p, CPU utilization rate (i.e., the first computing power node's CPU <= CPU_p); Mem_p, memory utilization rate (i.e., the first computing power node's Mem <= Mem_p); Online_p, online rate (i.e., the first computing power node's Online >= Online_p); and Success_p, computation success rate (i.e., the first computing power node's Success >= Success_p). The first computing power node is selected from the second computing power nodes based on the second computing power node requirements. If no first computing power node meets both the first and second computing power node requirements, the matching fails.

[0096] Optionally, the method, wherein scoring each first computing power node based on the first computing power node demand, the second computing power node demand, and the computing power information, and obtaining a computing power node score corresponding to each first computing power node, includes:

[0097] The absolute value of the difference between the multiple node computing power indicators of each first computing power node and the corresponding first computing power indicator value among the multiple first computing power indicator values ​​is multiplied by the corresponding first computing power indicator weight and then summed to obtain the first computing power node score; wherein, the first computing power node requirement includes multiple first computing power indicator values ​​and the first computing power indicator weights corresponding to the multiple first computing power indicator values ​​respectively; the computing power information includes multiple node computing power indicators.

[0098] The absolute value of the difference between the multiple node computing power indicators of each first computing power node and the corresponding second computing power indicator value among the multiple second computing power indicator values ​​is multiplied by the corresponding second computing power indicator weight and then summed to obtain the second computing power node score; wherein, the second computing power node requirement includes multiple second computing power indicator values ​​and the second computing power indicator weights corresponding to the multiple second computing power indicator values ​​respectively;

[0099] Based on the first computing power node score and the second computing power node score of each first computing power node, obtain the computing power node score corresponding to each first computing power node.

[0100] In this embodiment, Figure 4In step 401, the first computing power node requirement includes static and dynamic indicators. The dynamic indicators are the first computing power indicator values, including: CPU_r, Mem_r, Online_r, and Success_r. The first computing power node requirement also includes the weights of each first computing power indicator value. The first computing power indicator weights include: CPU_r_ratio, Mem_r_ratio, Online_r_ratio, and Success_r_ratio, where all four weights are non-negative and their sum is 1. The node computing power indicators include CPU, Mem, Online, and Success. The first computing power node score is calculated based on the node computing power indicators, the first computing power indicator values, and the first computing power indicator weights, using the following formula:

[0101] r1=CPU_r_ratio*(CPU_r-CPU)+Mem_r_ratio*(Mem_r-Mem)+Online_r_ratio*(Online-Online_r)+Success_r_ratio*(Success-Success_r).

[0102] exist Figure 5 In step 501, the second computing power node requirement includes the second computing power index value and the weight of the second computing power index corresponding to each second computing power index value. The second computing power index value includes: CPU_p, Mem_p, Online_p, and Success_p. The second computing power index weight includes: CPU_p_ratio, Mem_p_ratio, Online_p_ratio, and Success_p_ratio, where the four weights are non-negative numbers and the sum of the weights is 1. The node computing power index includes CPU, Mem, Online, and Success. The first computing power node score is calculated based on the node computing power index, the second computing power index value, and the second computing power index weight, using the following formula:

[0103] r2=CPU_p_ratio*(CPU_p-CPU)+Mem_p_ratio*(Mem_p-Mem)+Online_p_ratio*(Online-Online_p)+Success_p_ratio*(Success-Success_p).

[0104] The formula for the computing power node score is as follows:

[0105] r = (r1+r2) / 2.

[0106] The first computing power node with the highest computing power node score is selected as the target computing power node. If there is more than one target computing power node with the highest computing power node score, one can be randomly selected from the target computing power nodes.

[0107] like Figure 6 As shown, to achieve the above objectives, embodiments of the present invention provide a method for matching computing power nodes, wherein the method is executed by a first device and includes:

[0108] Step A10: Send a computing request to a first network device in the blockchain network; wherein, the computing request includes a data resource request and a first computing power node request; the data resource request is used by the first network device to present a data resource application to a second device that can provide the data resources requested by the data resource request; the first computing power node request is used by the first network device to determine a target computing power node that can provide computing.
