[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0042] In order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and order of execution.

[0043] In addition, the terms "including" and "having" in the embodiments, claims and drawings of the present application are not exclusive. For example, a process, method, system, product or device including a series of steps or modules is not limited to the listed steps or modules, and may also include steps or modules that are not listed.

[0044] In order to facilitate the understanding of the present application, the relevant elements involved in the present application are now described.

[0045] Blockchain Technology

[0046] Blockchain technology, also known as distributed ledger technology, is an emerging technology in which several computing devices jointly participate in "bookkeeping" (i.e. recording transaction data) and jointly maintain a complete distributed database. Blockchain technology has been widely used in many fields because of its decentralization (i.e. no central node), openness and transparency, each computing device can participate in database records, and data can be quickly synchronized between computing devices.

[0047] A blockchain system may include multiple blockchain nodes. A blockchain node is a device with communication and storage functions, such as a device storing a blockchain. For ease of description, this application uses nodes to represent blockchain nodes. In other words, all nodes involved in this application can be used to represent blockchain nodes, such as task release nodes, computing power nodes, etc.

[0048] Each node can both receive and generate information. Different nodes maintain communication by maintaining a common blockchain. Specifically, in a blockchain system, any node can generate a new block based on transaction-related data generated by each node in the blockchain system, and notify other nodes in the form of broadcast, and other nodes can verify the block. When all nodes in the blockchain system reach a consensus, the new block can be added to the blockchain.

[0049] The node in this application can be understood as a processing unit. In one implementation, the node can be a physical device, such as a server or a terminal device. In another implementation, the node can be a virtual computer; a virtual computer is a general term for the operating environment virtualized by software in all types of virtualized devices, and this concept includes virtual machines and containers. In other implementations, a node can be a process or a thread; a thread is the smallest unit that the operating system can perform computational scheduling. A thread is contained in a process and is the actual operating unit in the process; a process is a running activity of a program in a computer on a certain data set, and is the basic unit for resource allocation and scheduling in the system.

[0050] Block

[0051] In blockchain technology, transaction data is permanently stored in the form of electronic records, and the files that store these electronic records are called "blocks."

[0052] Blocks are generated one by one in chronological order. Each block records all transactions that occurred during its creation. All blocks are aggregated to form a chain of records. Since the throughput of nodes in different blockchain systems is different, the size of blocks may also be different in different blockchain systems.

[0053] It can be seen that the block records the transaction data within the time period of the block generation, so the main body of the block is actually a collection of transaction data. The structural design of each blockchain may not be exactly the same, but the block usually consists of two parts: the block header and the block body.

[0054] Among them, the block header is mainly used to record the characteristic value of the current block, which may include at least one of the following information: the identifier of the current block (such as the block number), the hash value of the block body in the current block, a timestamp (used to indicate the generation time of the block), the number of transactions (transaction count) and a random number (nonce). In addition, the block header may also include the hash value of the previous block (specifically the hash value of the block header in the previous block).

[0055] The block header includes multiple feature values. When determining the hash value of the block, it is necessary to connect the feature values ​​in the block header in order to form a string, and then calculate the hash value of the string. Since the values ​​of the feature values ​​included in the block headers of different blocks are usually different, each block uniquely corresponds to a hash value.

[0056] Since each block uniquely corresponds to a hash value and the block header of each block includes the hash value of the previous block, multiple blocks can form a blockchain.

[0057] A block can contain multiple transaction data.

[0058] As described in the background technology, when processing time-sensitive computing tasks, there is no relevant solution defined in the computing network to ensure that such computing tasks are completed within the specified time.

[0059] In response to the above problems, an embodiment of the present application provides a task processing method, which can split a task to be processed into multiple sub-tasks to be processed, and when the first computing power node determines that the processing end time of the processing result of a sub-task to be processed is after a preset time, the first computing power node is replaced with a second computing power node whose available computing power resources are greater than the preset computing power resources, thereby ensuring that other sub-tasks to be processed can be processed in a timely manner by computing power nodes with more available computing power resources, ensuring the processing time of the tasks to be processed, and improving the processing efficiency of the tasks to be processed.

[0060] The architecture of the blockchain system provided in the embodiments of the present application may include a network layer, a computing power layer, a consensus layer, and an application layer. Figure 1A A schematic diagram of a protocol architecture of a blockchain system provided by an embodiment of the present application is shown. Figure 1A Describe the protocol architecture of the blockchain system.

[0061] The network layer is used to realize information exchange between nodes in the blockchain network. The blockchain system is essentially a peer-to-peer (P2P) network system. Each node not only receives information but also generates information. Nodes maintain communication by maintaining a common blockchain. In the blockchain system, nodes can create new blocks. After the new blocks are created, they will notify other nodes in the form of broadcast. Other nodes will verify the blocks. When all nodes in the blockchain system reach a consensus, the new blocks can be added to the blockchain.

[0062] The computing power layer provides computing power resources in the blockchain system, processes pending tasks in the blockchain system, and generally provides an application programming interface (API) for calling. Technically speaking, the computing power layer mainly includes network programming, distributed algorithms, and encryption signatures.

[0063] Furthermore, the computing power layer also describes the storage form of blockchain data. Specifically, the computing power layer can include chain storage technology for block data, including timestamp technology, hash verification technology, etc.; it can also include the implementation method of the database and the interface implementation of the node calling the database.

[0064] Above the computing power layer is the consensus layer, which provides the functional implementation of the blockchain system based on the computing power layer. Through the basic capabilities provided by the computing power layer, the consensus layer can realize the recording of transaction data in the blockchain system and the control of the blockchain system. For example, smart contracts are a typical application of the consensus layer. Nodes can automatically execute contracts after certain conditions are met through the deployed smart contracts. For another example, the virtual currency trading market specifies the transaction method of virtual currency and the implementation details of the process through script encapsulation, which is also implemented in the consensus layer.

[0065] Above the consensus layer is the application layer, which encapsulates various application scenarios and cases of blockchain. The application layer is used to implement blockchain functions that interact directly with users, mostly in the form of clients.

[0066] In different blockchain systems, the specific implementation methods of each layer of the blockchain system architecture may vary. Figure 1A It is a schematic diagram of the protocol architecture of the blockchain system, not a limitation of the protocol architecture of the blockchain system.

[0067] Figure 1B A schematic diagram of the structure of the blockchain system 100 is shown. Figure 1B As shown, the blockchain system 100 includes: a task publishing node 101, multiple computing nodes 102 and an identity authentication server 103. Figure 1B The blockchain system shown has Figure 1A The protocol architecture is shown.

[0068] like Figure 1B As shown, based on the communication characteristics of the blockchain, each node device in the blockchain system 100 can be communicated with each other.

[0069] Optionally, the blockchain system 100 may include multiple task issuing nodes.

[0070] Figure 1B The nodes in the blockchain system 100 shown may include two types of nodes, namely: task publishing node 101 and computing power node 102.

[0071] Figure 1B The task publishing node 101 shown is also called a user node. In addition to being a medium for users to publish pending tasks in the blockchain system, the task publishing node 101 can also record transaction data, add blocks, delete blocks, and allocate computing nodes for processing pending tasks based on the consensus mechanism in the blockchain system 100 (such as the proof of stake (POS) consensus mechanism), that is, participate in the consensus.

[0072] Figure 1B The multiple computing nodes 102 in the blockchain system 100 shown have the same functions as the task issuing node 101, and can also provide input / output (IO) processing capabilities in the blockchain system, that is, provide computing resources to process pending tasks in the blockchain system.

[0073] It is understandable that all nodes in the blockchain system 100 are task issuing nodes (ie user nodes). When task issuing nodes provide computing resources in the blockchain system, these task issuing nodes providing computing resources are also called computing nodes.

[0074] Exemplarily, Table 1 shows the functions of a computing power node and a task publishing node.

[0075] Table 1

[0076] Node Type Providing computing resources Publish pending tasks Participate in consensus Computing Node √ √ √ Task release node √ √

[0077] Optional, Figure 1B The task publishing node 101 and the multiple computing nodes 102 shown may be terminals, servers, or other electronic devices for publishing tasks to be processed.

[0078] When the task issuing node 101 and the multiple computing nodes 102 are terminals, the terminal refers to a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core networks via a radio access network (RAN). The wireless terminal can be a mobile terminal, such as a computer with a mobile terminal, or a portable, pocket-sized, handheld, or computer-built-in mobile device that exchanges language and / or data with a radio access network, such as a mobile phone, tablet computer, laptop computer, netbook, or personal digital assistant (PDA). The embodiments of the present application do not impose any restrictions on this.

[0079] When the task issuing node 101 and the multiple computing nodes 102 are servers, they can be a single server, or a server cluster composed of multiple servers. In some implementations, the server cluster can also be a distributed cluster. This application embodiment does not impose any restrictions on this.

[0080] Figure 1B The identity authentication server 103 shown can be used to store the node identities of the task issuing node 101 and multiple computing nodes 102.

[0081] Optional, Figure 1BThe illustrated identity authentication server 103 may also provide identity registration services for nodes applying to join the blockchain system 100. For example, after obtaining the public key, private key, and identity information of the node applying to join the blockchain system 100, the identity authentication server 103 may provide the node with a public key certificate so that the node can communicate with other nodes in the blockchain system 100 based on the public key certificate.

[0082] Optional, Figure 1B The identity authentication server 103 shown can also be used to reveal the identity information of the node that publishes false information in the blockchain system 100.

[0083] The basic hardware structures of the task issuing node 101, the multiple computing nodes 102 and the identity authentication server 103 in the blockchain system 100 are similar, and all include Figure 2 or Figure 3 The components included in the communication device shown are described below. Figure 2 and Figure 3 Taking the communication device shown as an example, the hardware structure of the task publishing node 101, multiple computing nodes 102 and the identity authentication server 103 is introduced.

[0084] like Figure 2 , which is a schematic diagram of a hardware structure of a communication device provided in an embodiment of the present application. The communication device includes a processor 21, a memory 22, a communication interface 23, and a bus 24. The processor 21, the memory 22, and the communication interface 23 can be connected via a bus 24.

[0085] The processor 21 is the control center of the communication device, which can be a processor or a general term for multiple processing elements. For example, the processor 21 can be a general-purpose central processing unit (CPU) or other general-purpose processors. Among them, the general-purpose processor can be a microprocessor or any conventional processor.

[0086] As an embodiment, the processor 21 may include one or more CPUs, such as Figure 2 CPU0 and CPU1 are shown in the figure.

[0087] The memory 22 may be a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (RAM) or other type of dynamic storage device that can store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto.

[0088] In a possible implementation, the memory 22 may exist independently of the processor 21, and the memory 22 may be connected to the processor 21 via a bus 24 to store instructions or program codes. When the processor 21 calls and executes the instructions or program codes stored in the memory 22, the task processing method provided in the following embodiments of the present application can be implemented.

[0089] In the embodiment of the present application, for the task issuing node 101, the multiple computing nodes 102 and the identity authentication server 103, the software programs stored in the memory 22 are different, so the tasks issuing node 101, the multiple computing nodes 102 and the identity authentication server 103 implement different functions. The functions performed by each device will be described in conjunction with the following flowchart.

[0090] In another possible implementation, the memory 22 may also be integrated with the processor 21 .

[0091] The communication interface 23 is used for the communication device to connect with other devices through a communication network, and the communication network may be Ethernet, wireless access network, wireless local area network (WLAN), etc. The communication interface 23 may include a receiving unit for receiving data and a sending unit for sending data.

[0092] The bus 24 may be an industry standard architecture (ISA) bus, a peripheral component interconnect (PCI) bus, or an extended industry standard architecture (EISA) bus. The bus may be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 2Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.

[0093] It should be pointed out that Figure 2 The structure shown in the figure does not constitute a limitation on the communication device. Figure 2 In addition to the components shown, the communication device may include more or fewer components than shown, or combine certain components, or arrange the components differently.

[0094] Figure 3 FIG. 2 shows another hardware structure of the communication device in the embodiment of the present application. Figure 3 As shown, the communication device may include a processor 31 and a communication interface 32. The processor 31 is coupled to the communication interface 32.

[0095] The functions of the processor 31 may refer to the description of the processor 21. In addition, the processor 31 also has a storage function and can function as the memory 22 described above.

[0096] The communication interface 32 is used to provide data to the processor 31. The communication interface 32 may be an internal interface of the communication device, or an external interface of the communication device (equivalent to the communication interface 23).

[0097] It should be pointed out that Figure 2 (or Figure 3 ) does not constitute a limitation on the communication device, except Figure 2 (or Figure 3 ) In addition to the components shown in the figure, the communication device may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0098] like Figure 4 The figure is a flowchart of a task processing method provided in an embodiment of the present application. The task processing method is applied to the first computing power node. The first computing power node belongs to Figure 1B The blockchain system shown. The task processing method includes: S401-S403.

[0099] S401. The first computing power node obtains task information of a task to be processed.

[0100] The task information includes a plurality of subtask information corresponding to the plurality of to-be-processed subtasks one by one. The plurality of to-be-processed subtasks are obtained by splitting the to-be-processed task.

[0101] Since the pending task can be split into multiple pending subtasks, the first computing power node can process them in sequence according to the logical processing order of all the pending subtasks in the pending task.

[0102] Optionally, the first computing power node may be the first computing power node to process the pending task. In this case, the plurality of pending subtasks are all pending subtasks obtained by splitting the pending task. In this way, the first computing power node may receive the task information of the pending task sent by the task issuing node.

[0103] Correspondingly, the first computing power node may also be the Nth (N is an integer greater than 1) computing power node that processes the pending task. In this case, the multiple pending subtasks are parts of the pending subtasks obtained by splitting the pending task. In this way, the first computing power node can receive the multiple subtask information sent by the third computing power node and the processing result of the first subtask.

[0104] The third computing power node is a computing power node for processing the first subtask. The first subtask is: after all the subtasks to be processed are sorted according to the preset processing logic, the subtask that is located before the first subtask to be processed among the multiple subtasks to be processed.

[0105] S402. The first computing power node determines a processing result of a subtask to be processed among multiple subtasks to be processed, and publishes a processing end time of determining the processing result of the subtask to be processed.

[0106] A pending subtask is any pending subtask among the multiple pending subtasks.

[0107] Optionally, one of the multiple subtask information may include: a task program of a pending subtask corresponding to the subtask information and a startup script corresponding to the task program. In this way, after receiving the task information sent by the task publishing node, the first computing power node can parse the task information to determine the multiple subtask information, and run the task programs of the multiple pending subtasks in accordance with the startup scripts of the multiple pending subtasks in the multiple subtask information, thereby determining the processing results of the multiple pending subtasks.

[0108] It can be understood that if multiple subtasks to be processed are obtained by splitting the task publishing node according to the processing logic of the tasks to be processed, the first computing power node can run the task program of the first subtask to be processed according to the startup script of the first subtask to be processed, so as to determine the processing result of the first subtask.

[0109] Subsequently, the first computing power node may run the task program of the subtask to be processed adjacent to the first subtask to be processed based on the processing result of the first subtask to be processed and the startup script of the subtask to be processed adjacent to the first subtask to be processed, thereby determining the processing result of the subtask to be processed adjacent to the first subtask to be processed, until the processing results of multiple subtasks to be processed are determined.

[0110] Specifically, after determining the processing result of a pending subtask, the first computing power node can read the summary information of the pending task recorded in the temporary account book to determine the preset time corresponding to the pending subtask in the summary information.

[0111] Next, the first computing node can determine whether the processing end time corresponding to a pending subtask is after the preset time corresponding to the pending subtask. If so, the first computing node stops processing the unprocessed pending subtasks among the multiple pending subtasks, and adds the timeout information corresponding to the pending subtask in the temporary account book. If not, the first computing node continues to process the unprocessed pending subtasks among the multiple pending subtasks.

[0112] It is understandable that after determining the processing result of a pending subtask, the first computing power node may also publish the processing end time of determining the processing result of a pending subtask. Accordingly, other nodes in the blockchain system may receive the processing end time of determining the processing result of a pending subtask, and read the summary information of the pending task recorded in the temporary account book to determine the preset time corresponding to a pending subtask in the summary information.

[0113] Then, other nodes in the blockchain system can determine whether the processing end time corresponding to a pending subtask is after the preset time corresponding to a pending subtask. If so, other nodes in the blockchain system can add a timeout completion mark corresponding to a pending subtask in the temporary account book. If not, no processing is performed.

[0114] Optionally, when a block recording information generated in the current time period is created, all nodes in the blockchain system may store a timeout completion identifier corresponding to a pending subtask recorded in a temporary ledger in the current block.

[0115] Subsequently, the node that generates the next block after the current block can obtain the timeout completion flag corresponding to a pending subtask from the current block, and determine the summary information of the pending task to which a pending subtask belongs, thereby allocating a new computing power node to the pending task to ensure that the pending task is completed on time.

[0116] In this way, in the embodiment of the present application, all nodes in the blockchain system can jointly record multiple processing end times corresponding to multiple subtasks to be processed, thereby reliably supervising the processing process of the tasks to be processed.

[0117] Exemplarily, the processing logic of the preset pending task A is to process task program 1, task program 2 and task program 3 in sequence, then the task release node can split the pending task A into pending subtask 1, pending subtask 2 and pending subtask 3. Among them, the subtask information of the pending subtask 1 is task program 1 and the startup script corresponding to task program 1, the subtask information of the pending subtask 2 is task program 2 and the startup script corresponding to task program 2, and the subtask information of the pending subtask 3 is task program 3 and the startup script corresponding to task program 3.

[0118] Then, after obtaining the subtask information of the subtask 1 to be processed, the subtask information of the subtask 2 to be processed, and the subtask information of the subtask 3 to be processed sent by the task publishing node, the first computing power node can run the task program 1 of the subtask 1 to be processed according to the startup script of the subtask 1 to be processed, thereby determining the processing result of the subtask 1 to be processed, and broadcast the processing end time of the processing result of the subtask 1 to be processed.

[0119] Next, the first computing power node may run task program 2 of subtask 2 to be processed according to the processing result of subtask 1 to be processed and the startup script of subtask 2 to be processed, thereby determining the processing result of subtask 2 to be processed, and broadcasting the processing end time of the processing result of subtask 2 to be processed. Then, the first computing power node may run task program 3 of subtask 3 to be processed according to the processing result of subtask 2 to be processed and the startup script of subtask 3 to be processed, thereby determining the processing result of subtask 3 to be processed, and broadcasting the processing end time of the processing result of subtask 1 to be processed.

[0120] Optionally, the first computing power node may publish a message summary of the processing result of a pending subtask while publishing the processing end time of the processing result of the pending subtask, so as to enable the node that receives the processing result of the pending subtask to determine the correctness and completeness of the processing result of the pending subtask.

[0121] Optionally, the message digest of the processing result may be generated based on an existing message digest algorithm (eg, algorithms such as MD5 and SHA1).

[0122] S403. If the processing end time is after the preset time, the first computing power node determines a second computing power node whose available computing power resources are greater than the preset computing power resources, and sends to the second computing power node the processing results of the subtasks processed by the first computing power node and the subtask information of other subtasks to be processed among multiple subtasks to be processed, except for the subtasks processed by the first computing power node.

[0123] Specifically, if the processing end time is after the preset time, the first computing power node can stop processing the unprocessed pending subtasks among the multiple pending subtasks, and add a timeout completion mark corresponding to a pending subtask in the temporary account book.

[0124] Next, the first computing power node can determine a second computing power node whose available computing power resources are greater than the preset computing power resources, and send to the second computing power node the processing results of the subtasks processed by the first computing power node and the subtask information of other subtasks to be processed among multiple subtasks to be processed, except for the subtasks processed by the first computing power node, so as to transfer the other subtasks to be processed to the second computing power node with more computing power resources for processing, thereby ensuring the processing efficiency of the tasks to be processed.

[0125] In one achievable approach, combining Figure 4 ,like Figure 5 In the above S401, the method for the first computing power node to obtain the task information of the task to be processed specifically includes: S501-S502.

[0126] S501. When the plurality of to-be-processed subtasks are all to-be-processed subtasks obtained by splitting a to-be-processed task, the first computing power node receives task information sent by a task issuing node.

[0127] Specifically, when the task issuing node needs to issue a pending task in the blockchain system and determines that the first computing node is the computing node that undertakes the pending task, the task issuing node can split the pending task into multiple pending subtasks according to the processing logic of the pending task and issue the task information of the pending task to send the task information of the pending task to the first computing node.

[0128] Correspondingly, the first computing power node can obtain the task information of the pending tasks sent by the task publishing node.

[0129] S502: When the plurality of to-be-processed subtasks are partial to-be-processed subtasks obtained by splitting the to-be-processed task, the first computing power node receives the plurality of subtask information and the processing result of the first subtask sent by the third computing power node.

[0130] Specifically, when the plurality of to-be-processed subtasks are partial to-be-processed subtasks obtained by splitting the to-be-processed task, it means that the first subtask of all to-be-processed subtasks obtained by splitting the to-be-processed task has been processed by the third computing power node.

[0131] After the third computing power node determines the processing result of the last subtask in the first subtask that is sorted according to the preset processing logic, the third computing power node can publish the processing end time corresponding to the last subtask.

[0132] If the processing end time corresponding to the last subtask is after the preset time corresponding to the last subtask, the third computing power node can determine the first computing power node whose available computing power resources are greater than the preset computing power resources, and send the processing result of the first subtask to the first computing power node, as well as the subtask information of other subtasks to be processed among multiple subtasks to be processed except the first subtask.

[0133] Correspondingly, the first computing power node can receive the processing result of the first subtask sent by the third computing power node, as well as the subtask information of other subtasks to be processed except the first subtask among the multiple subtasks to be processed.

[0134] It should be noted that S501 and S502 are two different situations in which the first computing power node obtains task information of multiple to-be-processed subtasks. When S501 is executed, S502 is not executed; when S502 is executed, S501 is not executed.

[0135] In one achievable approach, combining Figure 5 ,like Figure 6 Described, before the first computing power node receives the task information sent by the task issuing node, the task processing method further includes: S601-S603.

[0136] S601. The first computing power node obtains summary information of the pending tasks issued by the task issuing node.

[0137] It should be understood that the method for the first computing power node to obtain the summary information of the pending tasks issued by the task issuing node can refer to the description in S401 and will not be repeated here.

[0138] Specifically, when a task issuing node needs to issue pending tasks to the blockchain system, it can generate and issue summary information of pending tasks to determine the computing nodes that can undertake the pending tasks. Correspondingly, other nodes in the blockchain system can receive the summary information of pending tasks issued by the task issuing node and record the summary information of pending tasks in a pre-configured temporary account book.

[0139] It should be noted that the task release node and multiple computing nodes are configured with temporary ledgers for real-time storage of information generated in the blockchain system. Later, when a new block is generated, the task release node and multiple computing nodes can store the information generated during the creation of the block in the temporary ledger. The task release node and multiple computing nodes store blockchains, and all nodes in the blockchain system store the same blockchain, which can be a consortium chain.

[0140] The summary information may include computing resource requirement information of the task to be processed, operating environment requirement information, and multiple preset times corresponding to multiple subtasks to be processed.

[0141] The computing power resource requirement information can be used to indicate the total computing power resources required to process the tasks to be processed.

[0142] The operating environment requirement information may include information such as the file size, software environment, and hardware environment of the task information of the task to be processed. The file size can be used to determine whether the computing power node meets the memory requirements of the task information of the task to be processed. The software environment and hardware environment can be used to determine whether the computing power node meets the software and hardware requirements of the task to be processed.

[0143] A preset time may be used to indicate a processing time threshold of a to-be-processed subtask corresponding to the preset time.

[0144] Optionally, the summary information of the task to be processed may also include multiple message summaries corresponding to multiple subtask information one by one, which are used for the node that obtains the multiple subtask information to determine the correctness and completeness of the multiple subtask information.

[0145] Optionally, the multiple message digests may be generated based on an existing message digest algorithm (eg, an MD5 message-digest algorithm (MD5) and a secure hash algorithm (SHA1) and other algorithms).

[0146] S602: If the available computing resources of the first computing power node meet the computing resource demand information, and the operating environment of the first computing power node meets the operating environment demand information, the first computing power node publishes a task acceptance message for indicating that it has accepted the task to be processed.

[0147] Specifically, after receiving the summary information of the pending tasks published by the task publishing node, the multiple computing nodes in the blockchain system can parse the summary information of the pending tasks to determine the computing resource requirement information, operating environment requirement information and multiple preset times corresponding to the multiple pending subtasks.

[0148] Then, when the available computing resources of at least one computing node (including the first computing node) among the multiple computing nodes meet the computing resource requirement information of the task to be processed, and the operating environment of at least one computing node meets the operating environment requirement information of the task to be processed, at least one computing node can publish a task acceptance message to indicate the acceptance of the task to be processed.

[0149] S603. When the first computing power node is determined by the task issuing node as the computing power node that undertakes the task to be processed, the first computing power node receives a node confirmation message issued by the task issuing node.

[0150] Among them, the node determination message is used to indicate that the first computing power node is determined as the computing power node that undertakes the processing task.

[0151] Optionally, after receiving the task acceptance message issued by at least one computing power node, the task issuing node can read the node information corresponding to at least one computing power node from the blockchain, and determine the computing power node that undertakes the task to be processed based on the node information.

[0152] When the first computing node among the at least one computing node is determined by the task issuing node as the computing node to undertake the task to be processed, the task issuing node may send the task information of the task to be processed to the first computing node. Correspondingly, the first computing node may obtain the task information of the task to be processed sent by the task issuing node.

[0153] The node information of a computing power node may include information such as available computing power resource information and operating environment information of a computing power node. For example, the task issuing node may determine the computing power node with the most available computing power resources as the computing power node that undertakes the task to be processed.

[0154] It should be noted that each of the multiple computing nodes in the blockchain system can publish information indicating the available computing resources corresponding to the computing node when joining the blockchain system, so as to facilitate the allocation of tasks to be processed by other nodes in the blockchain system. Subsequently, when the available computing resources of each of the multiple computing nodes increase or decrease, resource update information indicating the increase or decrease of available computing resources can also be published.

[0155] Exemplarily, the preset task publishing node A publishes the summary information of the pending task 1 in the blockchain system. In addition, the available computing resources of the first computing node B, computing node C, and computing node D meet the computing resource requirement information of the pending task 1, and the operating environment meets the operating environment requirement information of the pending task 1. Then the first computing node B, computing node C, and computing node D can publish the task acceptance message in the blockchain system.

[0156] Next, after the task issuing node A receives the task acceptance message issued by the first computing node B, computing node C and computing node D, it can read from the blockchain that the available computing power resources of the first computing node B are 8 gigahertz (GHz), the available computing power resources of computing node C are 7 GHz and the available computing power resources of computing node D are 4 GHz.

[0157] Next, task issuing node A may determine the first computing node B with the most available computing resources as the computing node to undertake the to-be-processed task 1, and send the task information of the to-be-processed task 1 to the first computing node B. Correspondingly, the first computing node B may obtain the task information of the to-be-processed task 1 sent by task issuing node A.

[0158] In one possible implementation, Figure 7 As shown, the method for a first computing power node to determine a second computing power node whose available computing power resources are greater than preset computing power resources specifically includes: S701-S702.

[0159] S701. The first computing power node obtains at least one block to be created, generated by at least one node in the blockchain system, for determining the second computing power node.

[0160] Among them, at least one node corresponds to at least one block to be created. A block to be created includes: a computing power node to be confirmed and pre-recorded summary information. The computing power node to be confirmed is a computing power node used to process other subtasks to be processed.

[0161] Specifically, if the processing end time of a pending subtask published by the first computing power node is after the preset time corresponding to the pending subtask, the first computing power node adds a timeout completion mark corresponding to the pending subtask in the temporary account book. Subsequently, the first computing power node can add the timeout completion mark to the current block.

[0162] Next, when the current block is generated, at least one node in the blockchain system that is ready to compete for the right to generate the next block after the current block can determine whether a timeout completion flag is recorded in the current block.

[0163] If yes, at least one node in the blockchain system can read the summary information of the pending task corresponding to a pending subtask recorded in advance from the temporary account book, and determine the computing power node whose available computing power resource information in the blockchain system is greater than the preset computing power resource from the temporary account book as the computing power node to be confirmed. The preset computing power resource can be a preset multiple (for example, 1.2 times or 1.5 times, etc.) of the available computing power resource of the first computing power node.

[0164] Then, each of the at least one node may publish a block to be created corresponding to it. Correspondingly, the first computing power node may receive at least one block to be created published by the at least one node.

[0165] S702. The first computing power node determines a node that meets a first preset condition from at least one node, and determines a computing power node to be confirmed in a block to be created generated by the node that meets the first preset condition as a second computing power node.

[0166] Among them, the first preset condition includes: the available computing power resources of the computing power node to be confirmed are greater than the preset computing power resources, and the pre-recorded summary information is the summary information of the task to be processed, and the transaction trust value of the computing power node is greater than the preset threshold.

[0167] Specifically, after receiving at least one block to be created, the first computing power node can read the behavior history record of at least one node corresponding to the at least one block to be created (such as transaction trust value and time of joining the blockchain system, etc.), and select a node that meets the behavior requirements (such as the highest transaction trust value) from at least one node as a candidate node.

[0168] Among them, the transaction trust value can be used as a reference value of the node's reputation in the blockchain system. When a new block is generated in the blockchain system, the node responsible for generating the block needs to consume a fourth preset amount of transaction trust value. At the same time, other nodes in the blockchain system that generate the block with parameters can obtain a fifth preset amount of transaction trust value. The fourth preset amount and the fifth preset amount can be preset manually based on experience.

[0169] Next, the first computing power node can determine whether the summary information of the pending tasks recorded in the block to be created corresponding to the candidate node is correct based on the summary information of the pending tasks recorded in the temporary account book, and can read the node information of the second computing power node from the blockchain to determine whether the available computing power resources of the second computing power node are greater than the preset computing power resources and whether the operating environment of the second computing power node meets the operating environment requirement information of the pending tasks.

[0170] Then, when the summary information of the task to be processed recorded in the block to be created corresponding to the candidate node is correct, and the available computing resources of the second computing power node are greater than the preset computing resources, and the operating environment of the second computing power node meets the operating environment requirement information of the task to be processed, the first computing power node can add the block to be created corresponding to the candidate node after the current block, to indicate the election of the candidate node as the node for generating the next block.

[0171] It can be understood that after other nodes in the blockchain system receive at least one block to be created issued by at least one node, the way in which the node that generates the next block is elected from at least one node can refer to the way in which the first computing power node elects a candidate node as the node that generates the next block, which will not be repeated here.

[0172] Optionally, any node in the blockchain system may issue a node confirmation message when determining that the candidate node is the node for generating the next block. Correspondingly, the first computing power node may receive node confirmation messages issued by other nodes in the blockchain system.

[0173] When the number of times a candidate node is elected is the largest among at least one node, it means that the candidate node is determined as the node to generate the next block in the blockchain system. Subsequently, the first computing power node may send the processing results of the subtasks processed by the first computing power node and the subtask information of other unprocessed subtasks among the multiple unprocessed subtasks, excluding the subtasks processed by the first computing power node, to the second computing power node.

[0174] In an implementable manner, the method for the first computing power node to send the processing results of the subtasks processed by the first computing power node and the subtask information of other unprocessed subtasks among the multiple unprocessed subtasks, excluding the subtasks processed by the first computing power node, to the second computing power node specifically includes: S801.

[0175] S801. When the number of blocks connected to the to-be-created block generated by the node that meets the first preset condition is greater than the first preset number, the first computing power node sends the processing results of the subtasks processed by the first computing power node and the subtask information of other unprocessed subtasks among the multiple unprocessed subtasks, excluding the subtasks processed by the first computing power node, to the second computing power node.

[0176] Optionally, the first preset number may be determined according to the number of nodes in the blockchain system.

[0177] Exemplarily, when the number of nodes in the blockchain system is less than or equal to 100, the first preset number may be 6.

[0178] When the number of nodes in the blockchain system is greater than 100, the block security threshold may be set manually according to experience to indicate that when the number of blocks connected to a block in the blockchain system is greater than the first preset number, the probability that the block is tampered with is less than the block security threshold. The number of nodes in the blockchain system, the system security threshold, and the first preset number satisfy the first formula. The first formula is:

[0179]

[0180] where h is the first preset number, S (0 < S < 1) is the system security threshold, and n is the number of nodes in the blockchain system. In an implementable manner, as Figure 8 shown, the task processing method further includes: S901 - S904.

[0181] S901. When the number of error messages published by the fourth computing power node is greater than the second preset number, the first computing power node publishes an identity disclosure request for revealing the node identity of the fourth computing power node.

[0182] Specifically, when the first computing power node receives error information published by the fourth computing power node in the blockchain system, the log record of the information published by the fourth computing power node can be read from the blockchain.

[0183] When it is determined that the amount of error information published by the fourth computing power node is greater than the second preset amount, the first computing power node may publish an identity disclosure request for disclosing the node identity of the fourth computing power node.

[0184] The error information includes: at least one of: junk information, task delegation failure information, or task forwarding error information. The identity disclosure request includes: the node identifier of the fourth computing power node and a log record corresponding to the error information.

[0185] S902. The first computing power node receives response messages issued by other nodes in the blockchain system.

[0186] The response message includes a response message agreeing to reveal the node identity of the fourth computing power node, or a response message disagreeing to reveal the node identity of the fourth computing power node.

[0187] It is understandable that the identity authentication server can receive response messages issued by any node in the blockchain system, and count the number of response messages that agree to reveal the node identity of the fourth computing power node, and the number of response messages that disagree to reveal the node identity of the fourth computing power node.

[0188] When the number of response messages agreeing to reveal the node identity of the fourth computing power node is greater than or equal to the third preset number, the identity authentication server may issue an identity disclosure message, wherein the identity disclosure message includes the node identity of the fourth computing power node.

[0189] Alternatively, when the number of response messages that disagree to reveal the node identity of the fourth computing power node is greater than or equal to a third preset number, the identity authentication server may issue a rejection message for refusing to reveal the node identity of the fourth computing power node.

[0190] S903. When the number of response messages agreeing to reveal the node identity of the fourth computing power node is greater than or equal to the third preset number, the first computing power node receives the identity disclosure message issued by the identity authentication server.

[0191] S904. When the number of response messages disagreeing to reveal the node identity of the fourth computing power node is greater than or equal to the third preset number, the first computing power node receives a rejection message issued by the identity authentication server for refusing to reveal the node identity of the fourth computing power node.

[0192] It should be noted that S903 and S904 are two different situations in which the first computing power node receives an identity disclosure message or a rejection message issued by the identity authentication server. When S903 is executed, S904 is not executed; when S904 is executed, S903 is not executed.

[0193] In one possible implementation, Fig. 9 As shown, the task processing method also includes: S1001-S1002.

[0194] S1001. When receiving an update message issued by any node in the blockchain system, the first computing power node records the update message.

[0195] Among them, the update message is any one of a task end message, a task release message, a block creation message, a task acceptance message, a node confirmation message, an identity disclosure message, a response message, an identity disclosure message and a rejection message.

[0196] The task end message includes the processing end time of the determined task processing result issued by any node. The task release message includes the summary information of the task issued by any node. The block creation message is used to indicate that any node has generated a block to be created.

[0197] Optionally, the update message can also be any other message released by a node in the blockchain system to the blockchain system. For example, the operator can build a consortium chain based on actual business needs, and deploy some online services (such as rental business, vehicle dispatch business, insurance claims business, credit service, medical service, etc.) based on the consortium chain. In this type of consortium chain, the update message can be a business message or business request with business intentions released by the user in the consortium chain; for example, the update message can also be a message sent by the user to the blockchain to change the information of the node (such as transaction trust value, etc.).

[0198] S1002. The first computing power node stores the update message in the corresponding block.

[0199] It is understandable that when any node in the blockchain system publishes an update message, other nodes record the update message in the temporary ledger. Later, when a new block is generated, the node in the blockchain system responsible for generating the new block can store multiple update messages generated during the creation of the new block in the block and publish the new block.

[0200] Accordingly, when a node in the blockchain system receives the new block, it can verify whether the multiple update information stored in the new block is consistent with the multiple update information recorded in its temporary account book. If they are consistent, the node in the blockchain system can add the new block to the blockchain.

[0201] In one possible implementation, Fig.10 As shown, the task processing method also includes: S1101-S1115.

[0202] S1101. The first computing power node sends an access request message to the identity authentication server.

[0203] Specifically, when the first computing power node needs to join the blockchain system, the first computing power node can send an access request message to the identity authentication server.

[0204] S1102. In response to the access request message, the identity authentication server sends an access response message to the first computing power node.

[0205] Among them, the access response message can be used to indicate that the identity authentication server agrees to the first computing power node to access the blockchain system, and requires the first computing power node to provide public key information, private key information, identity information and other information.

[0206] Optionally, the access response message may also include first confirmation information requiring the first computing power node to confirm whether to provide computing power resources to other nodes in the blockchain system.

[0207] S1103. The first computing power node sends a registration request message to the identity authentication server.

[0208] Among them, the registration message may include information such as the public key information, private key information and identity information of the first computing power node.

[0209] Optionally, the registration message may also include the communication address of the first computing power node, and second confirmation information indicating that the first computing power node confirms that it will provide computing power resources to other nodes in the blockchain system.

[0210] It can be understood that when the first computing power node confirms not to provide computing power resources to other nodes in the blockchain system, the first computing power node can be a task publishing node in the blockchain system.

[0211] S1104. The identity authentication server sends a registration response message to the first computing power node.

[0212] Specifically, after receiving the registration request message sent by the first computing power node, the identity authentication server can parse the registration request message to determine information such as the public key information, private key information, and identity information of the first computing power node.

[0213] Next, the identity authentication server can generate a public key certificate of the first computing power based on the public key information of the first computing power node, and securely store the private key information and identity information of the first computing power node.

[0214] Next, the identity authentication server may send a registration response message to the first computing power node, including the public key certificate of the first computing power node, as well as the public key certificates and communication addresses of other nodes in the blockchain system.

[0215] Correspondingly, the first computing power node can receive the registration response message sent by the identity authentication server and establish a communication connection with other nodes in the blockchain system to obtain blockchain data.

[0216] The registration response message may include the public key certificate of the first computing node, the public key certificates and communication addresses of other nodes in the blockchain system. The communication information of the first computing node may include the public key certificate and communication address of the first computing node.

[0217] Optionally, the identity authentication server may publish the communication information of the first computing power node in the blockchain system so that other nodes in the blockchain system know that the first computing power node has joined the blockchain system.

[0218] The public key certificate can be used to indicate the legal identity of the first computing power node that can communicate with other nodes in the blockchain system.

[0219] Optionally, the public key certificate may include a digital signature of the identity authentication server, which is used to indicate that the first computing power node has completed registration.

[0220] S1105. The task publishing node publishes a task publishing message.

[0221] The task release message includes summary information of the task to be processed.

[0222] S1106. The first computing power node publishes a task acceptance message to indicate that it has accepted the task for processing.

[0223] Specifically, if the available computing resources of the first computing power node meet the computing power resource demand information, and the operating environment of the first computing power node meets the operating environment demand information, the first computing power node can publish a task acceptance message to indicate that it has accepted the task for processing.

[0224] S1107. The task issuing node issues a node confirmation message.

[0225] S1108. The first computing power node sends a key negotiation message to the task issuing node.

[0226] Specifically, after receiving the node confirmation message issued by the task issuing node, the first computing power node can generate a transmission key that facilitates the secure transmission of task information, and read the public key certificate of the task issuing node from the blockchain to determine the public key information of the task issuing node.

[0227] Next, the first computing power node may encrypt the transmission key according to the public key information of the task issuing node to generate a key negotiation message, and send the key negotiation message to the task issuing node.

[0228] S1109. The task publishing node sends a task processing message to the first computing power node.

[0229] The task processing message includes task information of the task to be processed.

[0230] Specifically, after receiving the key negotiation message sent by the first computing power node, the task issuing node can parse the key negotiation message according to the private key information corresponding to its public key information to determine the transmission key.

[0231] Next, the task issuing node may encrypt the task information of the task to be processed according to the transmission key, and send a task processing message including the task information of the task to be processed to the first computing power node.

[0232] S1110. The first computing power node determines a processing result of a subtask to be processed among multiple subtasks to be processed, and publishes a processing end time of determining the processing result of the subtask to be processed.

[0233] S1111. If the processing end time is after the preset time, the first computing power node obtains at least one block to be created generated by at least one node in the blockchain system for determining the second computing power node.

[0234] S1112. The first computing power node determines a node that meets the first preset condition from at least one node, and determines the computing power node to be confirmed in the block to be created generated by the node that meets the first preset condition as the second computing power node.

[0235] S1113. The first computing power node sends a task confirmation message to the second computing power node.

[0236] Specifically, when the number of blocks connected to the block to be created generated by the node that meets the first preset condition is greater than the first preset number, the first computing power node can send a task confirmation message to the second computing power node.

[0237] The task confirmation message includes the processing result of the subtask processed by the first computing power node and the subtask information of other subtasks to be processed among the multiple subtasks to be processed except the subtask processed by the first computing power node.

[0238] S1114. The second computing power node processes the other subtasks to be processed among the multiple subtasks to be processed, except the subtasks that have been processed by the first computing power node.

[0239] Specifically, after receiving the task confirmation message, the second computing power node can parse the task confirmation message to determine the processing results of the subtasks processed by the first computing power node and the subtask information of other subtasks to be processed among multiple subtasks to be processed, except for the subtasks processed by the first computing power node.

[0240] Next, the second computing node can read the summary information of the pending task from the blockchain and determine whether the information in the task confirmation message is correct. If correct, the second computing node can process the other pending subtasks among the multiple pending subtasks except the subtasks that have been processed by the first computing node.

[0241] S1115. The second computing power node sends a processing completion message to the task issuing node.

[0242] The processing completion message includes processing results corresponding to all pending subtasks in the pending task.

[0243] Optionally, after determining the processing results of other subtasks to be processed except for the subtasks already processed by the first computing power node among multiple subtasks to be processed, the second computing power node may also publish in the blockchain system the processing end time of the processing results corresponding to all subtasks to be processed, so as to facilitate other nodes in the blockchain system to monitor the processing progress of the tasks to be processed.

[0244] Optionally, after the task issuing node may receive the processing completion message, the task issuing node may parse the processing completion message to determine the processing results corresponding to all pending subtasks, and verify whether the processing results corresponding to all pending subtasks are correct.

[0245] When errors occur in the processing results corresponding to one or more subtasks, the task issuing node can issue a reveal request message to apply for corresponding penalties on the second computing power node, etc.

[0246] The present application can split a pending task into multiple pending subtasks, and when the first computing power node determines that the processing end time of the processing result of a pending subtask is after a preset time, the first computing power node is replaced with a second computing power node whose available computing power resources are greater than the preset computing power resources, thereby ensuring that other pending subtasks can be processed in a timely manner through computing power nodes with more available computing power resources, ensuring the processing time of the pending tasks, and improving the processing efficiency of the pending tasks.
