Description

Method, device and electronic device for transaction processing in blockchain

technical field

This document relates to the field of blockchain technology, in particular to a method, device and electronic device for transaction processing in the blockchain.

Background technique

In some blockchain systems, the process of transaction processing can be shown in Figure 1, including the following four stages: collecting transactions → consensus → transaction execution → writing blocks. After the above process, a block can be generated. After a block (the Nth block in Figure 1) is generated, the transaction processing flow of the next block (the N+1th block in Figure 1) is entered.

As mentioned earlier, the transaction processing flow of a block in a blockchain system consists of four stages. After the Nth block is generated, the transaction processing flow of the N+1th block is entered. With this transaction processing method, at any point in time, the consensus node can only process one stage corresponding to one block. This method cannot make good use of the processing resources of nodes. For example, it cannot make good use of the parallel computing characteristics of multiple cores, and it is difficult to improve the performance of the blockchain system.

Figure 1 shows the general process of transaction processing by consensus nodes in a blockchain system. In some blockchain systems, not all consensus nodes perform the transaction collection operations in the above four phases. For example, in some blockchain systems that use master consensus algorithms (such as Practical Byzantine Fault Tolerance, PBFT, Practical Byzantine Fault Tolerance Algorithm), the consensus master node can perform the above four-stage operations, and the consensus non-master nodes can perform consensus → transaction execution →The operations of these three stages of writing blocks; it can also be that each consensus node performs all the operations of the above four stages. In other blockchain systems that use masterless consensus algorithms (such as Honey Badger Byzantine Fault Tolerant, HBBFT, Honey Badger Byzantine Fault Tolerant Algorithm), the consensus nodes do not distinguish between master nodes or non-master nodes, and each consensus node can perform the above four all operations in this stage.

The Chinese patent application publication number CN111522648A discloses a transaction processing method. The block chain node executes the block writing operation of the Nth round of transactions and the consensus execution operation of the N+1th round of transactions in parallel. A representative embodiment may be shown in Figure 2 (also Figure 2 of Patent Application Publication No. CN111522648A). As shown in Figure 2, the first thread and the second thread can be executed in parallel. During the N rounds of consensus and transaction execution by the first thread, the second thread can execute the block writing operation of the N-1 round of transactions in parallel; During the process of N+1 rounds of consensus and transaction execution, the second thread can perform the block writing operation of the Nth round of transactions in parallel; while the first thread performs N+2 rounds of consensus and transaction execution, the second thread can The block write operation of the N+1 round of transactions is performed in parallel. The above examples are mainly aimed at the situation that the consensus stage and the transaction execution stage take a relatively short time in the transaction processing process of the blockchain system, and the block writing stage takes a relatively long time. Therefore, the coupling relationship between the consensus operation and the transaction execution operation in the same round is maintained, and it is decoupled from the block writing operation in this round, so that two different threads can be used to execute (consensus + transaction execution) and write blocks respectively. In this way, in the process of executing the block writing operation of the previous block, the (consensus + transaction execution) operation of the next block can be executed in parallel, which is especially suitable for processing by computers with multi-core CPUs, thereby improving transaction processing efficiency. Make the blockchain system suitable for application scenarios with high business concurrency.

In fact, transactions collected in a certain round may include ordinary transfer transactions or transactions involving smart contracts. For ordinary transfer transactions, the processing time is generally relatively short, while for transactions involving smart contracts, the contract logic may be more complicated, or there may be many transactions involving contracts, so the processing time is relatively long. In this way, for transactions involving a large number of smart contracts, or for smart contracts containing complex logic, the processing time of the transaction execution link may be longer than that of the consensus link, and is closer to the processing time of the block writing operation. Even longer processing time than write block operations. In this way, only (consensus + transaction execution) and block writing are decoupled in this example, and there is still room for further optimization.

Detailed ways

In order to make the purpose, technical solutions and advantages of this document more clear, the technical solutions of this specification will be described clearly and completely below with reference to the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this document, but not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of this document.

The technical solutions provided by the embodiments of the present specification will be described in detail below with reference to the accompanying drawings.

One or more embodiments of this specification provide a transaction processing method in a blockchain. The schematic diagram of the implementation process is shown in FIG. 3 , including: Step 310 , the blockchain node executes the transaction execution operation corresponding to the Nth block.

The transaction corresponding to the Nth block may be a transaction that has reached a consensus in the blockchain system. Furthermore, in step 310, the blockchain node may execute the transaction corresponding to the Nth block that has reached a consensus.

The above transaction execution operation can be processed by the transaction execution thread in the blockchain node. The above consensus operations can be handled by consensus threads in blockchain nodes.

As described in the background art, the transaction processing process in a blockchain system generally includes four different operations: transaction collection, transaction consensus, transaction execution, and block writing. As mentioned above, each consensus node may perform all the operations in the above four stages, or some consensus nodes may perform the operations in the last three stages above without performing the operation of collecting transactions. In this way, for a consensus node that performs collection transactions, this operation can also be performed by a separate thread in the consensus node, eg, called a transaction collection thread. Specifically, as shown in FIG. 4 , before executing the transaction execution operation corresponding to the Nth block, the consensus node can query whether the transactions collected in the transaction memory pool meet the preset transaction collection conditions through the transaction collection thread. If the preset transaction collection conditions are met, the consensus node packages the transactions collected by the transaction memory pool through the transaction collection thread. In this way, the consensus node can get the proposal to be consensus. Further, the consensus node can perform operations in the consensus stage through the consensus thread.

Specifically, when the consensus node is the consensus master node in the blockchain system using the master consensus algorithm, or when the consensus node is the consensus node in the blockchain system using the master consensus algorithm, the consensus thread can collect transactions from Get the transaction corresponding to the Nth block in the thread. Further, a consensus proposal can be initiated based on the transaction, so as to perform the operation in the consensus stage, for example, the consensus operation can be performed by the consensus thread in the blockchain node.

In addition, when the consensus node is the consensus non-master node in the blockchain system using the master consensus algorithm, the blockchain node responds to the consensus proposal sent by other consensus nodes for the transaction corresponding to the Nth block, and based on the consensus proposal of the Nth block This consensus proposes a consensus operation. For example, consensus operations can be performed by consensus threads in blockchain nodes. In this case, since the consensus node responds to the sent consensus proposal, and the sent consensus proposal may include transactions to be agreed upon, the consensus node may not perform the operation of collecting transactions.

Since the consensus thread needs to obtain the transaction corresponding to the Nth block from the transaction collection thread, the order of transaction collection→consensus can still be maintained for the processing flow of transactions corresponding to the same block.

After the blockchain node completes the consensus operation on the transaction corresponding to the Nth block, it may perform the operation on the transaction corresponding to the Nth block in step 310 . For example, the transaction execution operation can be performed by the transaction execution thread in the blockchain node.

Similarly, after the consensus thread executes the consensus operation of the transaction corresponding to the Nth block, it transmits the consensus result to the transaction execution thread of the blockchain node. Therefore, the processing flow of the transaction corresponding to the same block is still the same. The order of consensus → transaction execution can be maintained.

Step 320, in the process of executing the transaction execution operation corresponding to the Nth block, the blockchain node executes the consensus operation on the transaction corresponding to the N+1th block in parallel.

Similarly, before starting the consensus operation on the transaction corresponding to the N+1th block, the consensus node can query whether the transactions collected in the transaction memory pool meet the preset transaction collection conditions through the transaction collection thread. If the preset transaction collection conditions are met, the consensus node packages the transactions collected in the transaction memory pool through the transaction collection thread, thereby forming a transaction corresponding to the N+1th block. In this way, the node can get proposals to be consensus. Further, the consensus node can perform the operation in the consensus stage through the consensus thread, that is, the consensus operation on the transaction corresponding to the N+1th block is performed in step 320.

Specifically, when the consensus node is the consensus master node in the blockchain system using the master consensus algorithm, or when the consensus node is the consensus node in the blockchain system using the master consensus algorithm, the consensus thread can collect transactions from Get the transaction corresponding to the N+1th block in the thread. Further, a consensus proposal can be initiated based on the transaction, so as to enter the operation of the consensus stage, for example, the consensus operation can be performed by the consensus thread in the blockchain node.

In addition, when the consensus node is the consensus non-master node in the blockchain system using the master consensus algorithm, the blockchain node responds to the consensus proposal sent by other consensus nodes for the transaction corresponding to the N+1th block, The consensus operation is performed based on the consensus proposal, for example, the consensus operation can be performed by the consensus thread in the blockchain node. In this case, since the consensus node responds to the sent consensus proposal, and the sent consensus proposal may include transactions to be agreed upon, the consensus node may not perform the operation of collecting transactions.

Since the consensus thread needs to obtain the transaction corresponding to the N+1th block from the transaction collection thread, the order of transaction collection → consensus can still be maintained for the processing flow of transactions corresponding to the same block.

If the blockchain node performs the process of collecting the transaction corresponding to the Nth block, and performs the process of collecting the transaction corresponding to the N+1th block, the blockchain node collects the transaction corresponding to the N+1th block. Then collect the transactions corresponding to the N+1th block. This is especially true when the blockchain node is assigned only one thread to collect transactions. Moreover, in the process of consensus on the transaction corresponding to the Nth block, the blockchain node performs the operation of collecting the transaction corresponding to the N+1th block in parallel.

The consensus operation of the blockchain node on the transaction corresponding to the N+1th block may be performed after a consensus is reached on the transaction corresponding to the Nth block. This is especially true when blockchain nodes are assigned only one consensus thread.

It should be noted that the consensus proposal for the Nth block and the consensus proposal for the N+1th block may be initiated by the same consensus node, or may be initiated by different consensus nodes. For example, the consensus operation of the block chain node on the Nth block may be initiated by the block chain node as the consensus master node, and the consensus operation on the N+1th block may be another block. Blockchain nodes are initiated as consensus master nodes and vice versa.

After the blockchain node completes the consensus operation on the transaction corresponding to the N+1th block, it can perform the operation on the transaction corresponding to the N+1th block. For example, the transaction execution operation can be performed by the transaction execution thread in the blockchain node.

Similarly, after the consensus thread executes the consensus operation of the transaction corresponding to the N+1th block, it transmits the consensus result to the transaction execution thread of the blockchain node. Therefore, for the processing flow of the transaction corresponding to the same block, It is still possible to maintain the order of consensus → transaction execution.

As shown in Figure 4, after the blockchain node completes the operation on the transaction corresponding to the Nth block, the blockchain node can also write the result of the transaction execution into the Nth block of the blockchain ledger. That is, write block operations. Similarly, in the process of executing the block writing operation corresponding to the Nth block, the block chain node executes the transaction execution operation corresponding to the N+1th block in parallel.

The blockchain node performs the operation on the transaction corresponding to the N+1th block, which may be performed after performing the operation on the transaction corresponding to the Nth block. This is especially true when a blockchain node is assigned only one transaction execution thread.

As shown in Figure 4, after the blockchain node completes the operation on the transaction corresponding to the N+1th block, the blockchain node can also write the result of the transaction execution into the N+1th area of the blockchain ledger. in the block. Similarly, the block-writing operation corresponding to the N+1th block by the blockchain node may be performed after the block-writing operation corresponding to the Nth block. This is especially true when a blockchain node is assigned only one block writer thread.

When the blockchain node performs the collection transaction operation corresponding to the N+1th block, the consensus operation of the Nth block may not be completed, so the consensus operation for the N+1th block cannot be started. At this time, the blockchain node can store the collected transaction corresponding to the N+1th block in the memory, and extract the N+th block from the memory after the corresponding consensus operation of the Nth block is completed. The transaction corresponding to 1 block, and start the consensus operation on the transaction corresponding to the N+1th block.

Similarly, when the consensus operation corresponding to the N+1th block is completed by the blockchain node, the transaction execution operation of the Nth block may not be completed, so the transaction execution of the N+1th block cannot be started. operate. At this time, the blockchain node can store the consensus result corresponding to the N+1th block in the memory, and extract the N+th block from the memory after the corresponding transaction execution operation of the Nth block is completed. The consensus result corresponding to 1 block, and the transaction execution operation corresponding to the N+1th block is started.

Similarly, when the block chain node executes the transaction execution operation corresponding to the N+1th block, the block writing operation of the Nth block may not be completed, so the N+1th block cannot be started yet. write block operations. At this time, the blockchain node can store the transaction execution result corresponding to the N+1th block in the memory, and extract the transaction execution result from the memory after the corresponding block write operation of the Nth block is completed. The transaction execution result corresponding to the N+1th block, and the block write operation corresponding to the N+1th block is started.
