Abstract
The embodiment of the specification discloses a transaction processing method, a transaction processing device and electronic equipment in a blockchain. The method comprises the following steps: executing a transaction execution operation corresponding to an Nth block by the block chain node, wherein the transaction corresponding to the Nth block has reached consensus in a block chain system; and in the process of executing the transaction execution operation corresponding to the Nth block by the block chain node, executing the consensus operation of the transaction corresponding to the (n+1) th block in parallel.
Description
The application relates to a patent application with the application number of 202110146211.6, the application date of 2021, 02 month and 03 days and the name of transaction processing method, device and electronic equipment in a blockchain.
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 phases: collecting transactions, consensus, executing transactions, writing blocks. Through the above process, one block can be generated. After one block (e.g., block N in fig. 1) is generated, the transaction process proceeds to the next block (e.g., block n+1 in fig. 1).
As previously described, the transaction processing flow for a block in a blockchain includes four phases. After the nth block is generated, a transaction processing flow of the n+1th block is entered. In such a transaction processing manner, at any point in time, the consensus node can process only one phase corresponding to one block. This approach does not make good use of the processing resources of the nodes, such as the parallel computing characteristics of the cores, nor is the performance of the blockchain system improved.
FIG. 1 illustrates a general process by which a consensus node in a blockchain system processes transactions. In some blockchain systems, not all consensus nodes perform the transaction collection operations in the four phases described above. For example, in some blockchain systems employing a primary consensus algorithm (e.g., PRACTICAL BYZANTINE FAULT TOLERANCE, PBFT, a practical bayer fault-tolerant algorithm), a consensus primary node may perform the four-phase operation described above, and a consensus non-primary node may perform the three-phase operation of consensus- > transaction execution- > block writing; or each consensus node performs all the operations of the four phases. In other blockchain systems employing non-master consensus algorithms (e.g., honey Badger Byzantine Fault Tolerant, HBBFT, meles bezels fault tolerance algorithm), the consensus nodes do not distinguish between master nodes or non-master nodes, and each can perform all of the four phases of operations described above.
The Chinese patent with the application publication number of CN111522648A discloses a transaction processing method, wherein a block chain point executes a writing block operation of an Nth round of transaction and a consensus execution operation of an (n+1) th round of transaction in parallel. A representative embodiment may be as shown in fig. 2 (also fig. 2 of the patent application publication No. CN111522648 a). As shown in fig. 2, the first thread and the second thread may execute in parallel, and in the process of N rounds of consensus and transaction execution by the first thread, the second thread may perform N-1 th round of writing block operation in parallel; in the process of carrying out N+1 rounds of consensus and transaction execution by the first thread, the second thread can carry out the writing block operation of the Nth round of transaction in parallel; in the process of carrying out N+2 rounds of consensus and transaction execution by the first thread, the second thread can carry out the writing block operation of the N+1 round of transaction in parallel. The above examples are mainly directed to the situation that in the blockchain transaction processing process, the occupation time of the consensus stage and the transaction execution stage is relatively short, and the occupation time of the block writing stage is relatively long. Thus, the coupling relationship of the consensus operation and the transaction execution operation in the same round is maintained, and the write block operation of the round is decoupled, so that two different threads can be adopted to respectively execute (consensus+transaction execution) and write block. In this way, in the process of executing the writing block operation of the previous block, the (consensus+transaction execution) operation of the next block can be executed in parallel, and the method is particularly suitable for processing by adopting a computer with a multi-core CPU, so that the transaction processing efficiency can be improved, and the blockchain system can be suitable for application scenes with high concurrency of business.
In fact, the transactions collected in a certain round may include ordinary transfer transactions, and may also include transactions involving smart contracts. For ordinary transfer transactions, the processing time is generally relatively short, while for transactions involving smart contracts, contract logic may be complex or transactions involving contracts may be more, so there may be cases where the processing time is relatively long. Thus, for a transaction involving a large number of smart contracts, or for a smart contract involving complex logic, the transaction execution link may be processed more often than the consensus link, more closely to the processing time of the write block operation, or even more often than the processing time of the write block operation. Thus, there is still room for further optimization in this example where only (consensus + transaction execution) and write blocks are decoupled.

Detailed Description
For the purposes, technical solutions and advantages of this document, the technical solutions of this specification will be clearly and completely described below with reference to specific embodiments of this specification and corresponding drawings. It will be apparent that the embodiments described are only some, but not all, of the embodiments of this document. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.
The following describes in detail the technical solutions provided by the embodiments of the present specification with reference to the accompanying drawings.
One or more embodiments of the present disclosure provide a transaction processing method in a blockchain, where an implementation flow chart is shown in fig. 3, including:
In step 310, the blockchain node performs a transaction execution operation corresponding to the nth block.
The transaction corresponding to the nth block may be a transaction that has been agreed upon in the blockchain system. Further, in step 310, the blockchain node may execute the transaction corresponding to the nth block that has reached the consensus.
The transaction execution operations described above may be handled by a transaction execution thread in a blockchain node. The consensus operations described above may be handled by consensus threads in blockchain nodes.
As described in the background, transaction processing in a blockchain typically includes four distinct operations, collecting transactions, transaction consensus, transaction execution, and writing blocks. It is mentioned that 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, but not the operations of collecting transactions. Thus, for a consensus node executing a collection transaction, this operation may also be performed by a separate thread in the consensus node, e.g., referred to as a transaction collection thread. Specifically, as shown in fig. 4, before executing the transaction execution operation corresponding to the nth block, the consensus node may query, through the transaction collection thread, whether the transaction collected in the transaction memory pool meets the preset transaction collection condition. And if the preset transaction collection condition is met, the consensus node packages the transaction collected by the transaction memory pool through the 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 with the master consensus algorithm or when the consensus node is a consensus node in the blockchain system without the master consensus algorithm, the consensus thread can acquire the transaction corresponding to the nth block from the transaction collecting thread. Further, a consensus proposal may be initiated based on the transaction to perform a consensus phase operation, such as by a consensus thread in the blockchain node.
In addition, when the consensus node is a consensus non-master node in the block chain system adopting the master consensus algorithm, the block link point responds to the consensus proposal of the transaction corresponding to the Nth block sent by other consensus nodes, and performs the consensus operation based on the consensus proposal. The consensus operation may be performed, for example, by a consensus thread in the blockchain node. In this case, since the consensus node is responsive to the transmitted consensus proposal, the transmitted consensus proposal may include a transaction to be consensus, and thus 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 collecting transaction thread, the sequence of collecting transaction- & gt consensus can be maintained for the processing flow of the transaction corresponding to the same block.
After the blockchain node completes the consensus operation for the transaction corresponding to the nth block, the executing operation for the transaction corresponding to the nth block in step 310 may be performed. The transaction execution operations may be performed, for example, by a transaction execution thread in the blockchain node.
Similarly, after the consensus thread performs the consensus operation of the transaction corresponding to the nth block, the consensus result is transferred to the transaction execution thread of the block chain node, so that the sequence of consensus-transaction execution can be maintained for the processing flow of the transaction corresponding to the same block.
In step 320, the blockchain node performs the consensus operation for the transaction corresponding to the n+1th block in parallel during the transaction performing operation corresponding to the nth block.
Similarly, the consensus node may query, via the transaction collection thread, whether the transaction collected in the transaction memory pool has met a predetermined transaction collection condition before performing a consensus operation on the n+1st block corresponding transaction. If the preset transaction collection condition is met, the consensus node packages the transaction collected by the transaction memory pool through the 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 consensus. Further, the consensus node may perform the consensus phase operation through the consensus thread, that is, the performing in step 320 performs the consensus operation on the n+1st block corresponding transaction.
Specifically, when the consensus node is a consensus master node in the blockchain system with the master consensus algorithm or when the consensus node is a consensus node in the blockchain system without the master consensus algorithm, the consensus thread can acquire the transaction corresponding to the n+1st block from the transaction collecting thread. Further, a consensus proposal may be initiated based on the transaction, thereby entering into operation of a consensus phase, such as may be performed by a consensus thread in a blockchain node.
In addition, when the consensus node is a consensus non-master node in the blockchain system adopting the master consensus algorithm, the blockchain link point responds to the consensus proposal of the transaction corresponding to the (n+1) th block sent by other consensus nodes, and performs the consensus operation based on the consensus proposal, for example, the consensus thread in the blockchain node can perform the consensus operation. In this case, since the consensus node is responsive to the transmitted consensus proposal, the transmitted consensus proposal may include a transaction to be consensus, and thus 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+1st block from the collection transaction thread, the order of collection transaction→consensus can be maintained for the processing flow of the transaction corresponding to the same block.
If the blockchain node performs a process of collecting transactions corresponding to the nth block and performs a process of collecting transactions corresponding to the n+1th block, the blockchain node collects transactions corresponding to the n+1th block followed by collecting transactions corresponding to the n+1th block. This is particularly true where the blockchain node has only one collection transaction thread assigned. Moreover, the blockchain node performs the operation of collecting the n+1th blockcorresponding transaction in parallel in the course of consensus on the nth proposal.
The block chain node may perform the consensus operation for the transaction corresponding to the n+1th block after the consensus operation for the transaction corresponding to the N-th block is achieved. This is particularly true where the blockchain node has only one consensus thread assigned.
It should be noted that, the consensus proposal of the nth block and the consensus proposal of the n+1th block may be initiated by the same consensus node or may be initiated by different consensus nodes. For example, the blockchain node may have a consensus operation for the nth block initiated by the blockchain node as a consensus master node, and a consensus operation for the n+1th block may have another blockchain node initiated by the consensus master node, and vice versa.
After the block chain node completes the consensus operation on the transaction corresponding to the n+1th block, the transaction execution operation on the transaction corresponding to the n+1th block can be performed. The transaction execution operations may be performed, for example, by a transaction execution thread in the blockchain node.
Similarly, after the consensus thread performs the consensus operation of the n+1th block corresponding transaction, the consensus result is transferred to the transaction execution thread of the block chain node, so that the sequence of consensus-transaction execution can be maintained for the processing flow of the same block corresponding transaction.
As shown in fig. 4, after the block link point completes the transaction execution operation corresponding to the nth block, the block chain node may also write the result of the transaction execution into the nth block of the block chain ledger, i.e. write the block operation. Similarly, in the process of executing the write block operation corresponding to the nth block, the block chain node executes the transaction execution operation corresponding to the (n+1) th block in parallel.
The blockchain node performs operations on transactions corresponding to the n+1th block, which may be performed after performing operations on transactions corresponding to the N-th block. This is particularly true where the blockchain node has only one transaction execution thread assigned.
As shown in fig. 4, after the block link point completes the execution operation on the transaction corresponding to the n+1th block, the blockchain node may also write the result of the transaction execution into the n+1th block of the blockchain ledger. Similarly, a write block operation for the n+1th block by a blockchain node may be performed after a write block operation for the N-th block. This is particularly true where the blockchain node has only one write block thread assigned.
When the block chain node performs the collection transaction operation corresponding to the n+1th block, the consensus operation of the N-th block may not be completed yet, and thus the consensus operation of the n+1th block cannot be started yet. At this time, the blockchain node may store the collected transaction corresponding to the n+1th block in the memory, and after the corresponding consensus operation of the N-th block is completed, extract the transaction corresponding to the n+1th block from the memory, and start the consensus operation for the transaction corresponding to the n+1th block.
Similarly, when the block chain node performs the consensus operation corresponding to the n+1th block, the transaction performing operation of the N-th block may not be completed yet, and thus the transaction performing operation of the n+1th block cannot be started yet. At this time, the blockchain node may store the consensus result corresponding to the n+1th block in the memory, and after the transaction execution operation corresponding to the n+1th block is completed, extract the consensus result corresponding to the n+1th block from the memory, and start executing the transaction execution operation corresponding to the n+1th block.
Similarly, when the transaction execution operation corresponding to the n+1th block is completed by the blockchain node, the writing block operation of the N-th block may not be completed yet, and thus the writing block operation of the n+1th block cannot be started yet. At this time, the blockchain node may store the transaction execution result corresponding to the n+1th block in the memory, and after the corresponding write block operation of the N-th block is completed, extract the transaction execution result corresponding to the n+1th block from the memory, and start executing the write block operation corresponding to the n+1th block.
By adopting the transaction processing method provided by the embodiment of the specification, when the transaction in the blockchain is processed, the blockchain node can process different stages of the corresponding transaction of different blocks in parallel, so that the computing capacity of the multi-core CPU is utilized, the operation efficiency of the blockchain system is greatly improved, and the performance is improved.
