Description

Technical Field

[0001] This application relates to the field of blockchain, and more specifically, to a transaction processing method, apparatus, and storage medium. Background Technology

[0002] There are multiple blockchain nodes on a blockchain network. In order to ensure that the transaction execution results of each node are consistent, the nodes determine the order of transaction execution through a consensus protocol and execute transactions sequentially in a serial manner. After the previous transaction is completed and the block state is stable, the node will execute the next transaction.

[0003] However, with the increasing prevalence of blockchain applications and the growth in transaction volume, the traditional serial execution method has become a bottleneck restricting blockchain performance. Currently, mainstream CPUs have a multi-core architecture, supporting multi-threaded program execution. However, blockchain transactions are executed serially, meaning that at any given moment, only one CPU core is utilized. Smart contract execution is confined to a single core, and the computing resources of the remaining cores are not effectively utilized, resulting in a significant waste of computing power. This leads to low concurrent execution efficiency on the blockchain, easily causing excessively long transaction queuing times, reducing user experience and overall system throughput.

[0004] There is currently no effective solution to the problem of low execution efficiency of transactions on the blockchain in related technologies. Summary of the Invention

[0038] The display may be, for example, a touchscreen liquid crystal display (LCD) that allows the user to interact with the user interface of the computer terminal 10 (or mobile device).

[0039] Under the aforementioned operating environment, this application provides the following: Figure 2 The transaction processing method shown. Figure 2 This is a flowchart of a transaction processing method according to Embodiment 1 of this application.

[0040] In step S201, the target node in the blockchain network receives multiple transaction instructions to be processed.

[0041] Optionally, the target node can listen to communications on the blockchain network to receive the consensus-reached block (i.e., the target block) and obtain multiple transaction instructions within it. Transaction instructions are data commands used to instruct smart contracts on how to execute operations; they include information about the transacting parties and the transfer amount. A multi-core processor integrates multiple independent processor cores on a single physical chip, each capable of executing independent threads, thus achieving substantial parallel computing.

[0042] Step S202: Utilize multiple cores of the target node's central processing unit to process multiple transaction instructions and obtain multiple transaction results.

[0043] It should be noted that the number of cores is equal to the number of trading orders, so as to enable multiple trading orders to be processed in parallel using multiple cores.

[0044] Optionally, a thread pool can be constructed based on multiple cores, pre-creating a preset number of threads (the preset number equals the number of CPU cores). Each thread in the thread pool is used to process one transaction instruction, and the thread pool is used to process multiple transaction instructions in parallel. This embodiment assumes that there is no mutual dependency between the multiple transaction instructions. Instead, parallel transactions are performed first, and then transaction conflict detection is performed based on multiple local transaction records. If the conflict detection result is that there is no conflict, it means that there is no mutual dependency between the transaction instructions, and the multiple local transaction records are determined as multiple transaction results. If the conflict detection result is that there is a conflict, it means that there is a mutual dependency between the transaction instructions. At this time, the multiple cores of the target node's CPU can be used to process the multiple transaction instructions serially to obtain multiple serial processing results; the multiple serial processing results are determined as multiple transaction results.

[0045] For example, 16 trading instructions are executed in parallel by 16 threads. During execution, each thread is responsible for one trading instruction, using its own core resources to complete operations such as calling the smart contract and calculating the account balance, and storing the results in its own local transaction record.

[0046] Step S203: Update the blockchain based on the results of multiple transactions to obtain the updated blockchain.

[0047] Optionally, if the transaction result is a partial transaction record, the transaction account and balance information in each partial transaction record are obtained, and all transaction account and balance information is written into the world state of the blockchain; if the transaction result is a serial processing result, the latest generated serial processing result is obtained, and multiple transaction accounts and their corresponding balance information (i.e., covering all records of multiple transactions in the serial processing) in the latest generated serial processing result are written into the world state of the blockchain. It should be noted that the blockchain network includes multiple nodes, the target node is one of the nodes where the transaction is to be executed, and the multiple nodes are used to maintain the blockchain.

[0048] In summary, by receiving multiple transaction instructions from the target node and processing them using the multiple cores of the target node's central processing unit to obtain multiple transaction results, the system achieves the processing of multiple transaction instructions using the node's multiple cores without compromising the atomicity of each transaction instruction, thus improving the execution efficiency of transactions on the blockchain.

[0049] To improve the execution efficiency of transactions on the blockchain, optionally, receiving multiple transaction instructions to be processed by a target node in the blockchain network includes: receiving a target block of the blockchain according to the target node, wherein the target block is a block confirmed as valid by the consensus algorithm; writing the target block into the blockchain storage corresponding to the target node according to the target node; and retrieving multiple transaction instructions from the blockchain storage according to the target node.

[0050] Optionally, the consensus algorithm is an algorithm used to reach a consensus on the validity of blockchain transactions. The target node first listens to the network to receive blocks confirmed as valid by the consensus algorithm, i.e., the target block, and then writes the target block into the target node's blockchain storage as the basis for subsequent transaction execution. Blockchain storage refers to multiple transaction instructions on the blockchain system stored on non-volatile memory, organized into blocks. World state storage refers to the business data on the blockchain system stored on non-volatile memory, organized into key-value pairs, including transaction accounts, balance information, and other business data.

[0051] In summary, by receiving the target block of the blockchain based on the target node, writing the target block into the blockchain storage corresponding to the target node, and retrieving multiple transaction instructions from the blockchain storage based on the target node, the execution efficiency of transactions on the blockchain is improved.

[0052] To improve the execution efficiency of transactions on the blockchain, optionally, multiple transaction instructions can be processed using multiple cores of the target node's central processing unit to obtain multiple transaction results. This includes: processing multiple transaction instructions in parallel using multiple cores of the target node's central processing unit to obtain multiple local transaction records, wherein there is a one-to-one correspondence between local transaction records and cores, and each local transaction record includes transaction account and balance information; performing transaction conflict detection on the multiple local transaction records to obtain conflict detection results, wherein the conflict detection results are used to characterize whether there are identical transaction accounts in different local transaction records; and if the conflict detection results indicate that there is no conflict, the multiple local transaction records are identified as multiple transaction results.

[0053] Optionally, the transaction instructions in this embodiment can refer to transaction instructions for blockchain smart contracts. The access operations of the blockchain smart contract to the world state include write operations (i.e., writing key-value pairs into the world state storage) and read operations (i.e., reading the key-value pair corresponding to the specified key name from the world state storage). The world state storage is the business data on the blockchain system stored on non-volatile memory, organized in key-value pairs, containing transaction accounts, balance information, and other business data. The transaction instructions provide the purpose of the transaction, while the world state provides the corresponding transaction account and balance information. Multiple empty lists can be created locally on the target node, and the world state can be accessed in parallel by multiple cores to process multiple transaction instructions. The processing results (i.e., parallel processing results) corresponding to all transaction instructions are stored in the corresponding empty lists, resulting in multiple local transaction lists. Each local transaction list contains a local transaction record, which contains the transaction account and updated balance information, with a one-to-one correspondence with the core that executed it. These local transaction records are isolated and not integrated into the overall blockchain state. After all core transactions have been executed, the local transaction records from all local transaction lists can be written to the global transaction result list. For example, the global transaction result list might include [(Account 1, Balance 1), (Account 2, Balance 2), (Account 3, Balance 3), (Account 4, Balance 4)]. When processing transaction instructions in parallel, multiple instructions may attempt to modify the same transaction account simultaneously. This can lead to data inconsistency or violate the atomicity of transactions. Therefore, transaction conflict detection is necessary before determining local transaction records as the final transaction results. Transaction conflict detection checks whether different local transaction records modify the same transaction account. If the conflict detection result indicates no conflict, meaning all local transaction records modify different transaction accounts, then these local transaction records can be directly determined as the final transaction results.

[0054] In summary, by utilizing multiple cores, parallel processing of multiple transaction instructions is achieved, and transaction conflict detection avoids violating the atomicity of transactions. If a contract (i.e., the transaction corresponding to a certain transaction instruction) takes too long to execute or has an infinite loop, it prevents other transaction instructions from being affected, thereby improving the execution efficiency of transactions on the blockchain.

[0055] To improve the execution efficiency of transactions on the blockchain, optionally, transaction conflict detection is performed on multiple local transaction records. The conflict detection results include: when the transaction account data format is a sequence number format, determining a global transaction account list based on the transaction accounts of multiple local transaction records; determining the root node of the binary search tree based on the transaction account with index zero in the global transaction account list; generating subtrees of the binary search tree layer by layer according to the order of index increment based on the transaction accounts in the global transaction account list; during the generation of subtrees of the binary search tree, if any newly generated subtree has a duplicate node with the previous subtree, the conflict detection result is determined to be a conflict; if none of the newly generated subtrees have duplicate nodes with the corresponding previous subtree, the conflict detection result is determined to be a non-conflict.

[0056] For example, when the data format of a trading account is a serial number (e.g., the serial number of trading account 1001), different trading accounts correspond to different serial number values. A global trading account list can be determined based on the trading accounts of multiple local trading records, for example, [1001, 1002, 1003, 1004, 1005, 1006]. Trading account 1001 is selected as the root node of a binary search tree. Starting from the trading account with index 1, subtrees of the binary search tree are generated layer by layer. Each subtree can include a left child node and a right child node. During the creation of a newly generated subtree, the trading account in the newly generated subtree is compared with the trading account in the previous subtree layer (in this embodiment, the root node is the initial subtree layer) (i.e., the current trading account). If the value of the account to be added is less than the value of the current account, and the left child node of the newly generated subtree is empty, then the left child node of the newly generated subtree is constructed based on the value of the account to be added. If the left child node is not empty, it is used as the new current account, and the size relationship between the account to be added and the current account is re-compared. If the value of the account to be added is greater than the value of the current account, and the right child node of the newly generated subtree is empty, then the right child node of the newly generated subtree is constructed based on the value of the account to be added. If the right child node is not empty, it is used as the new current account, and the size relationship between the account to be added and the current account is re-compared. If, during the size comparison, there are cases where the values ​​are equal, that is, there are duplicate nodes, then the conflict detection result is determined to be a conflict. If a binary search tree is constructed for all accounts in turn without duplicate nodes, then the conflict detection result is that there is no conflict.

[0057] In summary, when the transaction account data format is serial number format, a binary search tree is used to achieve efficient transaction conflict detection by using transaction accounts with multiple local transaction records, thereby improving the execution efficiency of transactions on the blockchain.

[0058] To improve the execution efficiency of transactions on the blockchain, optionally, transaction conflict detection is performed on multiple local transaction records. The conflict detection results include: obtaining all transaction accounts when the data format of the transaction accounts is not a sequence number format; constructing a list based on all transaction accounts and obtaining the length of the list to obtain a first length; constructing a set based on all transaction accounts and obtaining the length of the set to obtain a second length; if the first length and the second length are equal, the conflict detection result is determined to be that there is no conflict; if the first length and the second length are not equal, the conflict detection result is determined to be that there is a conflict.

[0059] For example, if the trading account data format is not a serial number format, extract all trading accounts and construct a Python list [abc, cbd, abd, bce, gdj, abc] based on these trading accounts, where each element in the list represents a trading account. The length of the list is obtained using the `len` function, resulting in a first length of 6. This allows the list to be converted into a set to quickly construct a set based on all trading accounts. The length of the set is then obtained using the `len` function, resulting in a second length of 5. Since the two lengths are not equal, a conflict is detected; otherwise, no conflict is detected.

[0060] In summary, when the transaction account data format is not serial number format, by constructing a list based on all transaction accounts, efficient transaction conflict detection is achieved, thereby improving the execution efficiency of transactions on the blockchain.

[0061] To improve the accuracy of transactions on the blockchain, optionally, after performing transaction conflict detection on multiple local transaction records and obtaining conflict detection results, the method further includes: if the conflict detection result indicates the existence of a conflict, using multiple cores of the target node's central processing unit to serially process multiple transaction instructions to obtain multiple serial processing results; and determining the multiple serial processing results as multiple transaction results.

[0062] Optionally, if the conflict detection result indicates a conflict, a fallback to serial processing can be implemented to avoid data inconsistencies caused by the same trading account being processed by more than two core processes simultaneously. Serial processing continues until all trading instructions are processed, with each serial processing step yielding a result. For example, before serial processing, initial information on six trading accounts and their balances is obtained (e.g., transactions from trading account A to trading account B, trading account C to trading account D, and trading account E to trading account F). This requires three processing steps. After the first processing... The process involves updating the balance information of transaction accounts a and b to obtain the first serial processing result. After the second processing, the balance information of transaction accounts c and d is updated to obtain the second serial processing result. After the third processing, the balance information of transaction accounts e and f is updated to obtain the third serial processing result. These multiple serial processing results are then identified as multiple transaction results. The world state of the blockchain can be written using the multiple transaction accounts and their corresponding balance information (which covers all records of multiple transactions in the serial processing) in the latest generated serial processing result (i.e., the third serial processing result), thereby updating the blockchain.

[0063] In summary, when the conflict detection result indicates the existence of a conflict, multiple transaction instructions are processed serially using multiple cores of the target node's central processing unit, resulting in multiple serial processing results. These multiple serial processing results are then identified as multiple transaction results, thereby improving the accuracy of transactions on the blockchain.

[0064] To improve the execution efficiency of transactions on the blockchain, optionally, updating the blockchain based on multiple transaction results includes: converting the transaction account and balance information in each local transaction record into key-value pair data to obtain multiple key-value pair data, wherein each key-value pair data includes a key name and a key value; and writing the multiple key-value pair data into the world state of the blockchain to update the blockchain.

[0065] For example, the transaction account can be used as the key, and the corresponding balance information of the transaction account can be used as the key value to generate key-value pair data corresponding to local transaction records, resulting in multiple key-value pair data. These multiple key-value pair data are then written into the world state store of the blockchain to update the blockchain's business data.

[0066] In summary, by converting the transaction account and balance information in each local transaction record into key-value pairs, multiple key-value pairs are obtained. These multiple key-value pairs are then written into the world state of the blockchain, thereby improving the execution efficiency of transactions on the blockchain.

[0067] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0074] The transaction processing apparatus provided in this application embodiment receives multiple transaction instructions to be processed from a target node in the blockchain network through a transaction receiving unit 301.
