[0045] In order to solve the problem of low business processing efficiency of blockchain systems in related technologies, the embodiments of the present application provide a transaction processing method, device, electronic device and storage medium.

[0046] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application may be combined with each other if there is no conflict.

[0047] In order to facilitate the understanding of this application, the technical terms involved in this application are:

[0048] User refers to the initiator of the transaction. The user can initiate a transaction through the client and enter the transaction processing flow;

[0049] Mempool is a temporary storage area for transactions, used to store transactions initiated by users. It is mainly responsible for temporarily storing unconfirmed transactions, waiting for further processing by the scheduler;

[0050] Scheduler is used to extract transactions from the memory pool and assign a unique incrementing nonce value to each transaction to ensure the order and uniqueness of the transaction. Then, the transaction with the assigned nonce and the signature of the scheduler is written into the ledger of the blockchain system. It plays a key role in coordinating and scheduling transactions in the processing process;

[0051] The Executor is used to obtain transactions with order from the ledger and execute the transactions of the smart contract in order. It uses a deterministic and isolated virtual machine sandbox environment to ensure the correctness and consistency of transaction execution;

[0052] Ledger is where transaction sets are stored. All sorted transactions will be written into the ledger, forming an unalterable record of the blockchain system.

[0053] Generally, a blockchain system includes multiple nodes, such as nodes 1-100. Assuming that node 1 generates a block, this block includes multiple sorted transactions, each transaction has a unique nonce value. After the block is generated, nodes 2-100 need to reach a consensus on this block. Among them, the process of node 1 generating a block is the process of transaction execution, and the process of nodes 2-100 reaching a consensus is the process of transaction verification. These processes are all carried out on the chain, which will inevitably affect the transaction efficiency on the chain.

[0054] To this end, in an embodiment of the present application, the execution of transactions is migrated to off-chain processing, and transaction sorting and data storage are performed on the chain. In this way, fewer transaction links need to be processed by the blockchain system, thereby improving the transaction processing efficiency of the blockchain system.

[0055] See also Figure 1 , Figure 1 A flowchart of a transaction processing method provided for an embodiment of the present application includes the following steps.

[0056] In step 101, transaction information of multiple transactions is obtained from a memory pool.

[0057] In actual applications, transaction information of multiple transactions can be obtained from the memory pool regularly.

[0058] In step 102, a plurality of transactions are sorted.

[0059] For example, a transaction identifier such as a nonce value is assigned to each transaction. Since the nonce value is unique and incremented, the purpose of sorting multiple transactions can be achieved.

[0060] In step 103, the transaction information and sorting information of the multiple transactions are written into the ledger of the blockchain system and stored by the blockchain system.

[0061] Among them, the sorting information of each transaction is such as the nonce value of this transaction. The blockchain system can be a public chain system or a consortium chain system.

[0062] In some embodiments, before the transaction information and sorting information of multiple transactions are written into the ledger of the blockchain system, the multiple transactions may also be signed to ensure the traceability of the business processing process on the blockchain system.

[0063] In this way, transactions are sorted and data is stored on the chain instead of being executed. Since there are fewer business links that need to be processed by the blockchain system, the transaction processing efficiency of the blockchain system can be improved.

[0064] In some embodiments, the verification phase of the transaction can also be moved off-chain, so the above process can also include the following steps:

[0065] In step 104, as required, the transaction information and sorting information of at least part of the transactions are obtained from the consensus ledger in the blockchain system.

[0066] Among them, requirements include what type of transactions to verify, which users initiate transactions to verify, etc. In short, requirements are used to describe the characteristics of transactions that need to be verified.

[0067] In step 105, based on the acquired transaction information of at least part of the transaction, the transaction is executed in the virtual machine sandbox environment according to the sorting information to obtain the execution result of each transaction.

[0068] That is, according to the transaction execution order indicated by the sorting information and based on the transaction information of each transaction, the transaction is executed in the virtual machine sandbox environment to obtain the execution result of the transaction.

[0069] Since the virtual machine sandbox environment is deterministic and isolated, the correctness and consistency of transaction execution can be ensured.

[0070] In addition, it is also possible to receive a transaction result query request from the user end, determine the target transaction, which is any transaction among multiple transactions, and then obtain the transaction information of the target transaction from the consensus ledger in the blockchain system. Then, based on the transaction information of the target transaction, the transaction is executed in the virtual machine sandbox environment to obtain the execution result of the target transaction, and the execution result of the target transaction is sent to the user end.

[0071] That is, off-chain verification can be performed in batches or individually when a user needs to view the execution results of a transaction. In either case, there is no need for on-chain verification, thus reducing the computational burden on the chain.

[0072] In this way, by separating the execution and verification of transactions from the chain and transferring them to the off-chain, the chain is only responsible for transaction sorting and data storage, which can effectively reduce the computing burden on the chain and improve the transaction processing concurrency and throughput capacity of the blockchain system.

[0073] The embodiment of the present application provides a public chain or alliance chain consensus acceleration solution based on data availability (DA), which migrates the execution and verification of transactions to off-chain processing, and only performs transaction sorting and data storage on the chain. The original three necessary processes of execution, sorting and verification are split into a two-layer structure of on-chain and off-chain, thereby improving the processing efficiency of on-chain transactions while ensuring the order and consistency of transactions.

[0074] See also Figure 2 , Figure 2 A schematic diagram of a transaction processing process provided for an embodiment of the present application, wherein the Scheduler can be deployed in a server cluster, the Executor can also be deployed in a server cluster, and the server clusters where the Scheduler and the Executor are deployed can be the same or different, including the following steps.

[0075] 1. The user sends a transaction to the memory pool.

[0076] The user initiates a transaction request through the client and sends the transaction to the memory pool, which acts as a buffer for transactions and is responsible for managing the collection of pending transactions. This is the starting point of the entire process.

[0077] 2. The scheduler periodically obtains transaction sets from the memory pool.

[0078] The scheduler can periodically obtain a batch of transaction sets (including multiple transactions) from the memory pool according to the scheduling strategy.

[0079] 3. The scheduler assigns a nonce value.

[0080] The scheduler assigns a unique and increasing nonce value to each transaction in the transaction set. The nonce value is a key field to ensure the order of transactions, which can ensure that the same transaction will not be processed repeatedly in the blockchain system and is executed in the correct order.

[0081] Here, the scheduler assigns a unique incrementing nonce to each transaction, which ensures that transactions are executed in sequence and avoids duplicate processing. This mechanism effectively guarantees the consistency and order of transactions and is the core design for achieving the stability and reliability of the blockchain system.

[0082] 4. The scheduler writes the signed transaction with the nonce value into the ledger.

[0083] After assigning the nonce value, the scheduler can broadcast the signed transaction to reach consensus and finally write it to the ledger.

[0084] The above 1 to 4 are equivalent to the transaction sorting and data storage stage, that is, the transaction sorting and data storage are carried out on the chain.

[0085] 5. The executor gets the transaction.

[0086] The executor obtains transactions from the consensus ledger and can obtain all or part of the related transactions with order according to demand, where the order refers to the nonce value.

[0087] 6. The executor executes the transaction.

[0088] The executor executes the relevant smart contract logic in the order of nonce values ​​from small to large. It can calculate the state based on the content of the transaction and dynamically maintain the state in the executor's memory.

[0089] The above 5 to 6 are equivalent to the execution and verification stage of the transaction. This process is carried out off-chain, which can reduce the computational burden on the chain.

[0090] 7. Return the transaction execution result.

[0091] Finally, the executor will feed back the execution result to the user. The user can understand the final status of the transaction through the execution result. This marks the end of the entire transaction processing process.

[0092] Here, the executor processes transactions in parallel off-chain, which can greatly improve business processing capabilities. Off-chain execution and verification can not only reduce the computing burden on the chain, but also process more transactions in parallel, improving transaction processing efficiency in high-concurrency scenarios.

[0093] The beneficial effects of the embodiments of the present application are as follows:

[0094] Improve transaction processing efficiency: By migrating execution and verification operations to the off-chain and using the on-chain as a data availability layer, the computational pressure on the chain can be significantly reduced, and the transaction processing speed and the overall throughput of the blockchain system can be improved;

[0095] Enhanced system scalability: Off-chain execution and verification can be flexibly expanded to support larger-scale concurrent transaction processing, which is very suitable for enterprise alliance chain scenarios;

[0096] Ensure data integrity and consistency: Only transactions are sorted and stored on the chain, ensuring the persistence and availability of transaction data.

[0097] Based on the same technical concept, an embodiment of the present application also provides a transaction processing device. The principle of solving the problem by the transaction processing device is similar to that of the above-mentioned transaction processing method. Therefore, the implementation of the transaction processing device can refer to the implementation of the transaction processing method, and the repeated parts will not be repeated.
