Description
Technical Field
The present disclosure relates to the field of computer software technologies, and in particular, to a method and an apparatus for concurrent processing of consensus and transaction synchronization, and an electronic device.
Background
In the blockchain system, after a transaction is sent out, the consensus node receiving the transaction broadcasts the transaction to other consensus nodes through the network. However, when the transaction amount is large, the problem that the transaction pools of the respective consensus nodes are not synchronized easily occurs, mainly because: there may be transactions that receive only the transaction hash and not the transaction body. In the process of consensus, the transaction body needs to be pulled, and if the transaction body is not received during verification, the verification cannot pass, so that the consensus efficiency and the consensus processing performance are influenced.
Disclosure of Invention
An object of the embodiments of the present disclosure is to provide a method, an apparatus and an electronic device for concurrent processing of consensus and transaction synchronization, so as to effectively improve consensus efficiency and consensus processing performance.

upon initiating a proposal packaging transaction, adding transactions in a transaction cache pool to a synchronization portion of the proposal and adding transactions in a transaction proposal pool to a sequencing portion of the proposal; wherein the transactions in the transaction cache pool comprise uncompleted synchronized transactions, and the transactions in the transaction offer pool are synchronized transactions;
Consensus is made on the transactions of the sequencing part while the transactions of the synchronization part are synchronized;
after consensus is reached, the current transaction in the transaction offer pool is moved out, and the transactions in the transaction cache pool are moved into the transaction offer pool.

a transaction packaging module for adding transactions in a transaction buffer pool to a synchronization portion of the proposal and adding transactions in a transaction proposal pool to a sequencing portion of the proposal when a proposal packaging transaction is initiated; wherein the transactions in the transaction cache pool comprise uncompleted synchronized transactions, and the transactions in the transaction offer pool are synchronized transactions;
a consensus module for consensus of the transactions of the sequencing part and, at the same time, synchronizing the transactions of the synchronization part;
and the execution module is used for moving out the current transaction in the transaction proposal pool and moving the transaction in the transaction cache pool into the transaction proposal pool after consensus is achieved.
In a third aspect, an electronic device is provided, including:
a processor; and
A memory arranged to store computer executable instructions that, when executed, cause the processor to:
upon initiating a proposal packaged transaction, adding transactions in a transaction cache pool to a synchronization portion of the proposal and adding transactions in a transaction proposal pool to a sequencing portion of the proposal; wherein the transactions in the transaction cache pool comprise uncompleted synchronized transactions, and the transactions in the transaction offer pool are synchronized transactions;
consensus is made on the transactions of the sequencing part while the transactions of the synchronization part are synchronized;
after consensus is reached, the current transaction in the transaction offer pool is moved out, and the transactions in the transaction cache pool are moved into the transaction offer pool.
In a fourth aspect, a computer-readable storage medium is presented, the computer-readable storage medium storing one or more programs that, when executed by an electronic device that includes a plurality of application programs, cause the electronic device to:

Therefore, the transaction can be synchronously carried in the consensus processing process and executed in parallel, which is equivalent to the time of contending for one block to synchronize the transaction without a transaction body, thereby avoiding the situation that the consensus cannot be normally executed when the transaction lacks the transaction body, and improving the consensus efficiency and the consensus processing performance.

Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.
In consideration of the conventional consensus process, when the number of transactions is large, the transactions in the transaction pool are not synchronized due to network transmission delay. In order to avoid the influence of asynchronous transactions on consensus, the following configuration improvements are made in the embodiment of the specification:
1. The transaction pool is divided into two parts: a transaction cache pool and a transaction proposal pool; the transaction cache pool is used for storing newly received transactions which are possible to receive only transaction hashes but not transaction bodies, so that the transactions can be distinguished from synchronized transactions and cached in the transaction cache pool; the transaction proposal pool is used for storing synchronized transactions which comprise both transaction hashes and transaction bodies.
2. The consensus proposal is divided into two parts: a synchronization portion and a sequencing portion; wherein the synchronization part is used for adding the transaction in the transaction cache pool; the sequencing portion is for adding a transaction in the transaction offer pool.
It should be understood that it is the improvement of the above configuration that the consensus and the transaction synchronization can be performed in a parallel processing manner, so that the time for pulling the transaction during consensus is saved, and the consensus processing performance is improved.
The following describes a parallel processing scheme resulting from the above configuration improvement with reference to a specific consensus process.
Referring to fig. 1, a schematic diagram of steps of a parallel processing method for consensus and transaction synchronization provided in an embodiment of the present disclosure, the parallel processing method being applicable to a blockchain system, and the parallel processing method may include the following steps:
Step 102: upon initiating a proposal packaging transaction, adding transactions in a transaction cache pool to a synchronization portion of the proposal and adding transactions in a transaction proposal pool to a sequencing portion of the proposal; wherein the transactions in the transaction cache pool comprise uncompleted synchronized transactions, and the transactions in the transaction offer pool are synchronized transactions.
As the above configuration is improved, the transaction in the transaction buffer pool is a new transaction received by the block, and there may be an out-of-synchronization condition in this part of the transaction, so that this part of the transaction may be stored in the transaction buffer pool first, and when a proposal packaging transaction is initiated, the transaction in the transaction buffer pool is added to the synchronization part of the proposal, and the synchronized transaction in the transaction proposal pool is added to the sequencing part of the proposal.
Step 104: the transactions of the sequencing portion are agreed upon, while the transactions of the synchronization portion are synchronized.
In the process of identifying the proposal, the embodiment of the specification is different from the prior art in that only the transaction added by the sequencing part in the proposal is identified, and simultaneously, the transaction added by the synchronization part in the proposal is synchronized.
Optionally, in this embodiment of the present specification, when synchronizing the transaction added by the synchronization part in the proposal, the method may specifically perform: pulling a transaction body of the transaction of the synchronization portion, and/or pulling a transaction hash of the transaction of the synchronization portion. In other words, a transaction that does not have a transaction request transaction body for the unsynchronized transactions of the synchronization section requests a transaction hash for the unsynchronized transactions of the synchronization section.
Step 106: after consensus is reached, the current transaction in the transaction offer pool is moved out, and the transactions in the transaction cache pool are moved into the transaction offer pool.
Optionally, after step 106, the method may further include: the transaction of the sequencing portion is performed.
Through the technical scheme, when the transaction is packaged, the transaction in the transaction cache pool is added to the synchronous part of the proposal, and the transaction in the transaction proposal pool is added to the sequencing part of the proposal; in this way, when the proposal is identified, only the transaction of the sequence part is identified, and the transaction of the synchronization part is synchronized; after consensus is achieved, the current transaction in the transaction offer pool is moved out, and the transactions in the transaction cache pool are moved into the transaction offer pool. Therefore, the transaction can be synchronously carried in the consensus processing process and executed in parallel, which is equivalent to the time of contending for one block to synchronize the transaction without a transaction body, thereby avoiding the situation that the consensus cannot be normally executed when the transaction lacks the transaction body and improving the performance of the consensus processing.
