[0029] The inventors have found that in the current blockchain related technologies, computing efficiency is mostly improved from the software level or the hardware level, and there is a problem of not fully utilizing the computing power resources in the blockchain network.

[0030] In view of this, in order to at least partially solve the above-mentioned problem, this embodiment provides a transaction verification method, which is applied to a target node in a blockchain network; wherein the target node is communicatively connected with at least one client.

[0031] In order to facilitate those skilled in the art to implement this solution, Figure 1 The blockchain network in this embodiment is introduced. The blockchain network provided in this embodiment can be regarded as a blockchain node as a whole, and the network includes multiple device nodes, and the multiple device nodes can be further divided according to the functions they undertake.

[0032] For example, multiple device nodes may include packaging nodes, test nodes, and verification nodes, where packaging nodes are used to generate blocks, test nodes are used to test network latency, and verification nodes are used to verify the legitimacy of transactions. Of course, in some embodiments, the same node can assume multiple functions. For example, the same node can serve as both a test node and a verification node.

[0033] The target node provided in this embodiment is any one of the multiple verification nodes. In different implementation scenarios, the target node can be different types of devices as long as they can provide corresponding computing power.

[0034] For example, in some embodiments, the target node may be a server. For example, it may be a Web server, an FTP server, a data processing server, etc. In addition, the server may be a single server or a server group. The server group may be centralized or distributed (for example, the server may be a distributed system). In some embodiments, the server may be local or remote relative to the client. In some embodiments, the server may be implemented on a cloud platform; as an example only, the cloud platform may include a private cloud, a public cloud, a hybrid cloud, a community cloud, a distributed cloud, an inter-cloud, a multi-cloud, etc., or any combination thereof. In some embodiments, the server may be implemented on an electronic device having one or more components.

[0035] Of course, the client provided in this embodiment can also be different devices in different implementation scenarios, as long as the corresponding computing power can be provided. For example, the client can be, but not limited to, a mobile terminal, a tablet computer, a laptop computer, or a built-in device in a motor vehicle, or any combination thereof. In some embodiments, the mobile terminal may include a smart home device, a wearable device, a smart mobile device, a virtual reality device, or an augmented reality device, or any combination thereof.

In some embodiments, the smart mobile device may include a smart phone, a personal digital assistant (PDA), a gaming device, a navigation device, or a point of sale (POS) device, or any combination thereof.

[0036] As an example to facilitate understanding of this embodiment, a schematic diagram of the structure of the target node is also provided. Figure 2 As shown, the target node includes a memory 120, a processor 130, and a communication unit 140. The memory 120, the processor 130, and the communication unit 140 are electrically connected to each other directly or indirectly to achieve data transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines.

[0037] The memory 120 may be, but is not limited to, a random access memory (RAM), a read only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable read-only memory (EEPROM), etc. The memory 120 is used to store a program, and the processor 130 executes the program after receiving an execution instruction.

[0038] The communication unit 140 is used to send and receive data through a network. The network may include a wired network, a wireless network, a fiber optic network, a telecommunication network, an intranet, the Internet, a local area network (LAN), a wide area network (WAN), a wireless local area network (WLAN), a metropolitan area network (MAN), a wide area network (WAN), a public switched telephone network (PSTN), a Bluetooth network, a ZigBee network, or a near field communication (NFC) network, or any combination thereof. In some embodiments, the network may include one or more network access points. For example, the network may include a wired or wireless network access point, such as a base station and / or a network switching node, through which one or more components of the service request processing system may be connected to the network to exchange data and / or information.

[0039] The processor 130 may be an integrated circuit chip having a signal processing capability, and the processor may include one or more processing cores (e.g., a single-core processor or a multi-core processor). By way of example only, the processor may include a central processing unit (CPU), an application-specific integrated circuit (ASIC), an application-specific instruction set processor (ASIP), a graphics processing unit (GPU), a physical processing unit (PPU), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic device (PLD), a controller, a microcontroller unit, a reduced instruction set computer (RISC), or a microprocessor, or any combination thereof.

[0040] Combine the following Figure 3The transaction verification method provided is elaborated in detail, such as Figure 3 As shown, the method includes:

[0041] S101, obtaining transaction records to be allocated.

[0042] In some implementations, considering that the target node is a dedicated node in the blockchain, its computing power is much higher than that of the client. Therefore, after the target node obtains the records to be verified, it will be verified by the target node first; when the records to be verified exceed its own computing power, the remaining records to be verified will be used as transaction records to be allocated and allocated to each client for verification.

[0043] For example, assuming that the target node can process a maximum of 1,000 records to be verified, and the number of records to be verified obtained is 1,500, the excess 500 records will be allocated to the client as transaction records to be allocated, so that the client can help verify the legitimacy of these 500 records.

[0044] Among them, a transaction record can be considered illegal in many cases. For example, suppose a transaction record pays 100 virtual currencies, but the payer's wallet only has 50 virtual currencies. Therefore, before packaging the transaction records into blocks, illegal transaction records need to be removed.

[0045] S102, allocating the transaction record to at least one client.

[0046] In some embodiments, the target node is allocated based on the computing power of each client. That is, the target node can obtain the computing power of at least one client; then, based on the computing power of at least one client, the transaction record is allocated to at least one client, wherein the transaction record allocated to each client is positively correlated with the computing power of the client.

[0047] For example, the allocation can be made according to the following formula:

[0048]

[0049] In the formula, Num i Indicates the number of transaction records allocated to the i-th client, cap i It represents the computing power of the i-th client, and txs represents the total amount of transaction records to be allocated.

[0050] In some implementations, for each client, the target node obtains the computing resources of the client and determines the computing power of the client based on a preset metric.

[0051] The computing resources may include the client's memory information, CPU information, and network quality information. For example, the memory information may include information such as the capacity and frequency of the memory; the CPU information may include information such as the CPU model, frequency, and number of cores; and the network quality information may include information such as communication delay and packet loss rate.

[0052] As a computing power measurement standard, this embodiment pre-configures corresponding weights for various types of computing resources, and uses the weighted results of various types of computer resources as computing power.

[0053] For example, the calculation can be performed according to the following formula:

[0054] cap source =M*0.2+C*0.5+Q net *0.3;

[0055] In the formula, cap source Indicates the computing power of the client, M indicates memory information, C indicates CPU information, Q net Indicates network quality information.

[0056] S103, receiving a legal transaction sent by at least one client.

[0057] Among them, legal transactions include verified transaction records.

[0058] Based on the above design, after the target node obtains the transaction records to be allocated, it allocates them to the clients that are connected to it so that each client can verify whether the allocated transaction records are legal records; then, each client will feedback the legal records that have passed the verification to the target node. In this way, the target node can make full use of the computing power resources in the blockchain network to improve the data processing efficiency in the blockchain network.

[0059] In this embodiment, when acquiring the communication quality information of the client, in order to make the communication quality information obtained by the test more objective, a test node is periodically selected from a plurality of verification nodes.

[0060] For example, serial numbers may be configured for multiple verification nodes in advance, and then the test node may be determined from them according to the following formula:

[0061]

[0062] Where t represents the time when the test node is selected, T * represents the reference time, Δt is the time interval, N represents the number of test nodes, index represents the sequence number corresponding to the selected test node, and ceil represents rounding up. For example, ceil(0.3)=1.

[0063] In some implementations, for the test node selected in the above manner, each client in this embodiment sends a test message to the test node and then receives a response message to the test message; then, the time difference between the two is used as network quality information.

[0064] In this embodiment, in order to encourage clients to participate in verifying transaction records, the target node also counts the verification workload of each client; the verification workload is used as a free transaction certificate in the blockchain network.

[0065] It should be understood that when a blockchain wallet is configured in the client, when the client initiates a transaction, in addition to the virtual currency required for the transaction, a certain handling fee must also be paid. In this embodiment, a conversion relationship between the verification workload and the free transaction voucher is configured; when the client has a free transaction voucher, the transaction can be initiated without paying a handling fee.

[0066] In some embodiments, the target node is used to package the right of the block, generate a block including legal transactions, and send the block to the blockchain network.

[0067] In some other embodiments, the blockchain network includes a packaging node, and the target node sends the received legal transactions to the packaging node. The packaging node receives legal transactions from all verification nodes, packages them into blocks, and sends them to the network.

[0068] Based on the same inventive concept as the transaction verification method, this embodiment also provides a device related to the method, including:

[0069] This embodiment provides a transaction verification device, which is applied to a target node in a blockchain network, and the target node is connected to at least one client.

Figure 4 As shown, from a functional perspective, the transaction verification device may include:

[0072] The transaction allocation module 202 is used to allocate the transaction record to at least one client, wherein the at least one client is used to verify the transaction record.

[0076] It should be noted that the transaction verification device may also include other software modules for implementing other steps or sub-steps of the transaction verification method; of course, the transaction acquisition module 201, the transaction allocation module 202, and the transaction processing module 203 may also be used to implement other steps or sub-steps of the transaction verification method. This embodiment does not make specific limitations on this, and those skilled in the art may make appropriate adjustments according to their respective classification standards, and this embodiment does not make specific limitations on this.
