Description

Transaction processing method and device in block chain and electronic equipment

Technical Field

The present disclosure relates to the field of blockchain technologies, and in particular, to a method and an apparatus for processing transactions in a blockchain, and an electronic device.

Background

In some blockchain systems, the flow of transaction processing may be as shown in fig. 1, including the following four stages: collect transaction → consensus → transaction execution → write block. Through the above process, a tile can be generated. After a block (e.g., the nth block in fig. 1) is generated, the transaction processing flow of the next block (e.g., the (N + 1) th block in fig. 1) is entered.

As mentioned above, the transaction processing flow of a tile in the blockchain system includes four stages. After the nth block is generated, the transaction processing flow of the (N + 1) th block is entered. In such a transaction processing manner, at any time point, the consensus node can only process one stage corresponding to one block. This approach does not make good use of the processing resources of the nodes, for example, the parallel computing characteristics of multiple cores are not made good use of, and the performance of the blockchain system is difficult to be improved.

Fig. 1 shows a general process for processing a transaction by a consensus node in a blockchain system. In some blockchain systems, not all of the common nodes perform the transaction collection operations in the four phases described above. For example, in some block chain systems using a main consensus algorithm (e.g., Practical Byzantine Fault Tolerance, PBFT), the consensus master node may perform the four phases of operations, and the consensus non-master node may perform the three phases of operations of consensus → transaction execution → block writing; or each common node may perform all the operations of the four phases. In some other blockchain systems that use an algorithm without main consensus (e.g., honeyy Badger Byzantine Fault Tolerant, HBBFT, Badger bazaltion Fault-Tolerant algorithm), the nodes with consensus do not distinguish between main nodes or non-main nodes, and each node with consensus can perform all the above four phases of operations.

Chinese patent application publication No. CN111522648A discloses a transaction processing method, in which block chain nodes execute block writing operation of the nth round of transaction and consensus execution operation of the N +1 th round of transaction in parallel. A representative embodiment may be as shown in fig. 2 (which is also fig. 2 of the patent application publication No. CN 111522648A). As shown in fig. 2, a first thread and a second thread may be executed in parallel, and during the execution of N rounds of consensus and transaction by the first thread, the second thread may perform a block writing operation for the N-1 st round of transaction in parallel; in the process that the first thread carries out N +1 rounds of consensus and transaction execution, the second thread can carry out block writing operation of Nth round of transaction in parallel; during the process of carrying out N +2 rounds of consensus and transaction execution by the first thread, the second thread can carry out block writing operation of N +1 round of transaction in parallel. The above example mainly aims at the situation that the occupation time of the consensus phase and the transaction execution phase is short and the occupation time of the block writing phase is long in the transaction processing process of the blockchain system. Thus, the coupling of the consensus operation and the transaction execution operation in the same round is maintained, while being decoupled from the write block operation of the round, so that two different threads can be used to execute (consensus + transaction execution) and write block, respectively. In this way, in the process of executing the block writing operation of the previous block, the operation of (consensus + transaction execution) of the next block can be executed in parallel, and the method is particularly suitable for processing by a computer adopting a multi-core CPU (central processing unit), so that the transaction processing efficiency can be improved, and the blockchain system can be suitable for application scenes with high business concurrence.

In fact, transactions collected in a certain round may include ordinary transfer transactions and transactions involving smart contracts. For ordinary transfer transactions, the processing time is generally relatively short, whereas for transactions involving smart contracts, the contract logic may be more complex, or transactions involving contracts may be more numerous, such that the processing time may be relatively long. Thus, for transactions involving a large number of transactions involving smart contracts, or for smart contracts involving complex logic, the transaction execution link may have a processing time that is longer than the processing time of the consensus link, closer to the processing time of the write block operation, or even longer than the processing time of the write block operation. Thus, only the (consensus + trade execution) and write blocks are decoupled in this example, and there is still further room for optimization.

Detailed Description

In order to make the purpose, technical solutions and advantages of this document more clear, the technical solutions of this specification will be clearly and completely described below with reference to specific embodiments of this specification and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of this document, and not all embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step based on the embodiments in this description belong to the protection scope of this document.

The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.

One or more embodiments of the present specification provide a method for processing a transaction in a blockchain, where an implementation flow diagram is shown in fig. 3, and the method includes:

instep 310, the block node performs a transaction execution operation corresponding to the nth block.

The transaction corresponding to the nth block may be a transaction that has agreed in the blockchain system. Further, instep 310, the block link point may execute the transaction corresponding to the nth block that has been agreed upon.

The transaction execution operation may be processed by a transaction execution thread in a blockchain node. The above consensus operation may be handled by a consensus thread in a blockchain node.

As described in the background, the transaction processing in blockchain systems typically includes four distinct operations, collecting transactions, transaction consensus, transaction execution, and writing blocks. As mentioned above, each consensus node may perform all the operations of the four phases, or some consensus nodes may perform the operations of the last three phases without performing the operation of collecting transactions. Thus, for a consensus node performing a collect transaction, this operation may also be performed by a separate thread in the consensus node, e.g., referred to as a transaction collect thread. Specifically, as shown in fig. 4, before the execution of the transaction execution operation corresponding to the nth block begins, the consensus node may query, through the transaction collection thread, whether the transactions collected in the transaction memory pool have satisfied the preset transaction collection condition. And if the preset transaction collection condition is met, the consensus node packs the transactions collected by the transaction memory pool through a transaction collection thread. In this way, the consensus node can get a proposal to be consensus. Further, the consensus node may perform the operation of the consensus phase through a consensus thread.

Specifically, when the consensus node is a consensus master node in the blockchain system adopting the master consensus algorithm, or the consensus node is a consensus node in the blockchain system adopting the masterless consensus algorithm, the consensus thread may obtain the transaction corresponding to the nth block from the collected transaction thread. Further, a consensus proposal may be initiated based on the transaction to perform a consensus phase operation, e.g., a consensus thread in a blockchain node may perform the consensus operation.

In addition, when the consensus node is a consensus non-master node in the blockchain system adopting the master consensus algorithm, the blockchain node responds to consensus proposals of transactions corresponding to the Nth block sent by other consensus nodes, and performs consensus operation based on the consensus proposals. The consensus operation may be performed, for example, by a consensus thread in a blockchain node. In this case, since the consensus node is in response to the sent consensus offer, and the sent consensus offer may include the transaction to be agreed upon, the consensus node may not perform the operation of collecting the transaction.

Since the consensus thread needs to acquire the transaction corresponding to the nth block from the collection transaction thread, the sequence of collection transaction → consensus can still be maintained for the processing flow of the transaction corresponding to the same block.

After the block link point completes the consensus operation on the transaction corresponding to the nth block, the transaction execution operation corresponding to the nth block instep 310 may be performed. The transaction execution operation may be performed, for example, by a transaction execution thread in a blockchain node.

Similarly, after the consensus operation of the nth block-corresponding transaction is completed, the consensus result is transmitted to the transaction execution thread of the block-linked node, so that the sequence of consensus → transaction execution can still be maintained for the processing flow of the same block-corresponding transaction.

Instep 320, during the process of executing the transaction execution operation corresponding to the nth block, the block nodes execute the consensus operation corresponding to the (N + 1) th block in parallel.

Similarly, before the consensus operation is performed on the transaction corresponding to the (N + 1) th block, the consensus node may query, through the transaction collection thread, whether the transaction collected in the transaction memory pool has satisfied the preset transaction collection condition. And if the preset transaction collection condition is met, the consensus node packs the transactions collected by the transaction memory pool through a transaction collection thread, so that the transaction corresponding to the (N + 1) th block is formed. In this way, the node can get a proposal to be agreed upon. Further, the consensus node may perform the operation of the consensus phase through the consensus thread, i.e., perform the consensus operation on the (N + 1) th block corresponding transaction instep 320.

Specifically, when the consensus node is a consensus master node in the blockchain system adopting the master consensus algorithm, or the consensus node is a consensus node in the blockchain system adopting the masterless consensus algorithm, the consensus thread may obtain the transaction corresponding to the (N + 1) th block from the collected transaction thread. Further, a consensus proposal may be initiated based on the transaction to enter into a consensus phase, e.g., a consensus thread in a blockchain node may perform the consensus operation.

When the consensus node is a consensus non-master node in the blockchain system using the master consensus algorithm, the blockchain node responds to consensus suggestions for the transaction corresponding to the (N + 1) th block from other consensus nodes, and performs consensus operations based on the consensus suggestions, for example, the consensus operations may be performed by a consensus thread in the blockchain node. In this case, since the consensus node is in response to the sent consensus offer, and the sent consensus offer may include the transaction to be agreed upon, the consensus node may not perform the operation of collecting the transaction.

Since the consensus thread needs to acquire the transaction corresponding to the (N + 1) th block from the collection transaction thread, the sequence of collection transaction → consensus can still be maintained for the processing flow of the transaction 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 + 1) th block, the blockchain node collects the transaction corresponding to the (N + 1) th block and then collects the transaction corresponding to the (N + 1) th block. This is particularly true where only one gather transaction thread is assigned to a blockchain node. And the blockchain node performs the operation of collecting the transaction corresponding to the (N + 1) th block in parallel in the process of identifying the transaction corresponding to the Nth block.

The consensus operation of the block link point on the transaction corresponding to the (N + 1) th block may be performed after the consensus on the transaction corresponding to the nth block is achieved. This is particularly true where only one consensus thread is assigned to a blockchain node.

It should be noted that the consensus proposal for the nth block and the consensus proposal for the (N + 1) th block may be initiated by the same consensus node or by different consensus nodes. For example, the consensus operation for the block-linked point for the nth block may be initiated by the block-linked point as the consensus master, while the consensus operation for the (N + 1) th block may be initiated by another block-linked point as the consensus master, or vice versa.

After the block link point completes the consensus operation on the transaction corresponding to the (N + 1) th block, the transaction corresponding to the (N + 1) th block may be executed. The transaction execution operation may be performed, for example, by a transaction execution thread in a blockchain node.

Similarly, after the consensus operation of the (N + 1) th block-corresponding transaction is performed by the consensus thread, the consensus result is transmitted to the transaction execution thread of the block link point, so that the sequence of consensus → transaction execution can still be maintained for the processing flow of the same block-corresponding transaction.

As shown in fig. 4, after the block link point completes the operation of executing the transaction corresponding to the nth block, the block link point may also write the result of executing the transaction into the nth block of the block chain book, i.e., a block writing operation. Similarly, during the block link point executing the block writing operation corresponding to the nth block, the transaction executing operation corresponding to the (N + 1) th block is executed in parallel.

The block link point may perform the operation on the transaction corresponding to the (N + 1) th block after performing the operation on the transaction corresponding to the nth block. This is particularly true where only one transaction execution thread is assigned to a blockchain node.

As shown in fig. 4, after the block link point completes the operation of executing the transaction corresponding to the (N + 1) th block, the block link point may also write the result of executing the transaction into the (N + 1) th block of the block chain ledger. Similarly, the block link point may perform a write block operation on the N +1 th block after the write block operation on the nth block. This is particularly true where the blockchain node has only one write block thread assigned.

When the block chain node completes the collection transaction operation corresponding to the (N + 1) th block, the consensus operation for the nth block may not be completed yet, and thus the consensus operation for the (N + 1) th block cannot be started yet. At this time, the block link point may store the collected transaction corresponding to the (N + 1) th block in the memory, extract the transaction corresponding to the (N + 1) th block from the memory after the corresponding consensus operation of the nth block is completed, and start the consensus operation on the transaction corresponding to the (N + 1) th block.

Similarly, when the block node completes the consensus operation corresponding to the (N + 1) th block, the transaction execution operation of the nth block may not be completed, and thus the transaction execution operation of the (N + 1) th block may not be started. At this time, the block link point may store the consensus result corresponding to the (N + 1) th block in the memory, and after the transaction execution operation corresponding to the nth block is completed, extract the consensus result corresponding to the (N + 1) th block from the memory, and start to execute the transaction execution operation corresponding to the (N + 1) th block.

Similarly, when the transaction execution operation corresponding to the (N + 1) th block is completed, the block writing operation for the nth block may not be completed, and thus the block writing operation for the (N + 1) th block may not be started. At this time, the block chain node may store the transaction execution result corresponding to the (N + 1) th block in the memory, and after the block writing operation corresponding to the nth block is completed, extract the transaction execution result corresponding to the (N + 1) th block from the memory, and start to execute the block writing operation corresponding to the (N + 1) th block.

By adopting the transaction processing method provided by the embodiment of the specification, when the transaction in the blockchain system is processed, the blockchain link points can process different stages of the corresponding transaction of different blocks in parallel, the computing power of the multi-core CPU is utilized, the operation efficiency of the blockchain system is greatly improved, and the performance is improved.
