Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described The embodiments are only some of the embodiments in this specification, not all of them. 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 specification.

As mentioned earlier, the current block chain completes the four operations of transaction collection, consensus, execution and block writing in a serial manner, which leads to relatively low processing efficiency of block chain transactions and limits the use of block chains. throughput. As the blockchain becomes more and more popular in all walks of life, the business volume will also show explosive growth. Obviously, the current transaction processing method is difficult to apply to scenarios with high business concurrency in the future. In response to this problem, this document aims to provide a technical solution that can improve the efficiency of blockchain transaction processing.

Fig. 1 is a flow chart of a processing method of a blockchain transaction according to an embodiment of this specification. The method shown in Figure 1 can be executed by the corresponding blockchain nodes below, including the following steps:

S102. Collect the first batch of transactions in the Nth round consensus proposal of the blockchain, where the Nth round consensus proposal includes multiple batches of transactions, and N is a positive integer.

It should be noted that this article does not specifically limit the transaction batch division logic proposed by the N-th round of consensus. However, any scheme that divides the transactions in the N-th round of consensus proposals into multiple batches shall fall within the scope of protection of the embodiments of this specification.

As an exemplary introduction: In the embodiment of this specification, each blockchain node of the blockchain can uniformly batch all transactions proposed by the N-th round of consensus according to the corresponding transaction initiation time based on the smart contract set in advance. subdivided. Alternatively, according to the order of transactions in the N-th round of consensus proposals, all transactions proposed by the N-th round of consensus are divided into batches.

S104, execute the consensus operation on the first batch of transactions, and if there is a second batch of transactions, execute the collection operation of the second batch of transactions in parallel in batch order, the second batch of transactions is the Nth round of consensus proposals that have not been completed Collected batches of transactions.

It should be understood that the batch transactions that have not been collected in this step may include batch transactions that have not yet started collection, or batch transactions that have started collection but have not yet completed collection. The batch order is the batch division order described in S102 above.

In the embodiment of this specification, the blockchain nodes collect the transactions proposed by the N round of consensus in batches. After the target batch of transactions is collected, it can be executed at the same time: the consensus execution operation of the target batch of transactions and the collection operation of the next batch of transactions corresponding to the target batch of transactions. That is to say, the second batch of transactions mentioned in this step refers to the next batch of transactions of the first batch of transactions.

S106, perform transaction execution operations on the first batch of transactions, and if there is a third batch of transactions in parallel, perform consensus operations on the third batch of transactions in batch order, the third batch of transactions has been collected for the Nth round of consensus proposals Batch transactions that have completed and have not yet completed consensus.

It should be understood that the batches of transactions whose consensus has not been completed in this step may include batches of transactions that have not yet started consensus, or batches of transactions that have started consensus but have not yet completed consensus.

Similarly, in the embodiment of this specification, the blockchain nodes perform consensus operations on the transactions proposed by the N-th round of consensus in batches. After the consensus operation of the target batch of transactions is completed, it can be executed simultaneously: the execution operation of the target batch of transactions and the consensus operation of the next batch of transactions corresponding to the target batch of transactions. That is to say, the third batch of transactions mentioned in this step refers to the next batch of transactions of the second batch of transactions.

S108, sending the transaction execution results of the first batch of transactions in the blockchain to perform transaction confirmation on the first batch of transactions.

Specifically, the block chain node as the execution subject of this step can send the transaction confirmation request of the transaction execution result of the first batch of transactions to other block chain nodes in the block chain; if 2f other block chain nodes are received later If the transaction confirmation feedback is sent, the transaction confirmation of the first batch of transactions is confirmed. Among them, f is the maximum number of abnormal consensus nodes allowed by the blockchain.

S110. After obtaining the transaction confirmations of all the batches of transactions proposed by the N-th round of consensus, perform a block writing operation on all the batches of transactions proposed by the N-th round of consensus.

It should be understood that in the embodiment of this specification, the blockchain nodes perform consensus operations on the transactions proposed by the N-th round of consensus in batches, but in the end, only one block writing operation may be performed. That is to say, in the embodiment of this specification, all batches of transactions proposed by the Nth round of consensus can be recorded in one block.

Based on the method in the embodiment of this specification, the blockchain nodes can execute collection, transaction consensus, transaction execution, and transaction confirmation in batches for each round of consensus proposals. In particular, while performing consensus operations on the intermediate batch of transactions proposed by each round of consensus, the execution operations of the previous batch of transactions and the collection operations of the next batch of transactions are also performed, thereby shortening the blockchain transaction time in parallel. Processing time, thereby improving the throughput of the blockchain to meet the needs of high-concurrency business scenarios.

In addition, after the transaction confirmation of the first batch of transactions is obtained, the transaction execution results of the first batch of transactions can also be fed back to the corresponding blockchain client. That is to say, in the method of the embodiment of this specification, the block chain node can immediately feed back the transaction execution to the block chain client after each batch of transactions completes the transaction execution and gets the transaction confirmation, thereby significantly reducing the transaction time. The transaction confirmation delay on the client side of the block chain improves the user experience.

Or, in order to reduce the resource overhead of interacting with the blockchain client side, it is also possible to execute all batches of transactions proposed by the N-round consensus after the transaction confirmation of all batches of transactions proposed by the N-round consensus The results are uniformly fed back to the corresponding blockchain client.

In practical applications, the feedback strategy for transaction execution results can be determined based on the number of transactions in the N-th round of consensus proposals. For example, when the number of transactions in the N-th round of consensus proposals exceeds the preset threshold, you can choose to immediately feed back the transaction execution results to the blockchain client after each batch of transactions is executed and confirmed. Similarly, when the number of transactions in the N-round consensus proposal does not exceed the preset threshold, you can choose to complete the transaction execution and get transaction confirmation for all batches of transactions proposed by the N-round consensus proposal, and then send the N-round consensus proposal The transaction execution results of all batches of transactions are uniformly fed back to the corresponding blockchain client.

In addition, it should also be understood that the method in this embodiment of the specification can continuously process multiple rounds of consensus-proposed transactions.

In the following, the working principle will be described in detail by taking the continuous processing of the transaction in the consensus proposal of the Nth round and the N+1 round as an example of the embodiment method of this specification.

Referring to Figure 2, the method of the embodiment of this specification can set the first thread, the second thread, the third thread, the fourth thread and the fifth thread to be executed in parallel, so as to respectively execute the collection, consensus, and transaction of blockchain transactions. These five operations are execution, transaction confirmation, and block writing.

Among them, the first thread is used to collect transactions in batches, that is, the first thread does not collect other batches of transactions before collecting a batch of transactions; the second thread is used to perform consensus operations on transactions in batches, that is, the first thread The second thread does not execute the consensus operations of other batches of transactions before executing the consensus operation of a batch of transactions; the third thread is used to execute the execution operations of transactions in batches, that is, before executing the execution operations of a batch of transactions The execution operations of other batches of transactions are not executed. The fourth thread performs transaction confirmation in batches, that is, the transaction confirmation of other batches of transactions is not performed before the transaction confirmation of one batch of transactions is completed. The fifth thread executes block writing operations uniformly after all batches of transactions proposed by each round of consensus are confirmed.

Take the first batch of transactions described above as an example. After the first thread has collected the first batch of transactions, notify the second thread to perform consensus operations on the first batch of transactions; after the second thread has completed the consensus operations of the first batch of transactions, notify the third thread to The first batch of transactions is executed; after the third thread executes the execution operations of the first batch of transactions, the fourth thread is notified to confirm the first batch of transactions.

Here, the consensus proposals of round N and round N+1 are divided into three batches of transactions as an example. Using the working principle of the above thread, the consensus proposals of round N and round N+1 can be presented as shown in Figure 2. time slot relationship.

It can be seen from Figure 2:

If all batches of transactions in the Nth round of consensus proposals are collected when the consensus operation is performed on the first batch of transactions, then the collection operation of the batches of transactions in the N+1th round of consensus proposals is performed in batch order .

If there is a second batch of transactions when the transaction execution operation is performed on the first batch of transactions, the operation of collecting the second batch of transactions in batch order is executed in parallel.

If all batches of transactions in the Nth round of consensus proposals are collected when the transaction execution operation is performed on the first batch of transactions, the collection operation of the batches of transactions in the N+1th round of consensus proposals is performed in batch order .

If all batches of transactions in the Nth round of consensus proposals have completed the consensus when executing the transaction execution operation on the first batch of transactions, then execute the collected but not yet completed consensus in the order of batches in the N+1th round of consensus proposals Consensus operation of batch transactions.

If all batches of transactions in the Nth round of consensus proposals have been collected when the first batch of transactions is written to the block, then the batch transactions in the N+1th round of consensus proposals are executed in batch order. Collect operations.

If all batches of transactions in the Nth round of consensus proposals have completed the consensus when writing blocks for the first batch of transactions, then perform consensus on the collected but not yet completed consensus transactions in the N+1th round of consensus proposals in batch order. Consensus operation of batch transactions.

It should also be understood that orderly execution of transactions is also important. Assume that in a transaction scenario, user A needs to remit 10,000 yuan to user B, and then user B remits 5,000 yuan to user C. Assuming that the initial balance of user B is 3,000 yuan, if the transactions are not executed in sequence, that is, user B first remits 5,000 yuan to user C, and user A remits 10,000 yuan to user B, then user B will fail to remit money to user C The problem.

Therefore, in order to avoid such transaction logic problems, each round of consensus proposes that the subsequent batch of transactions cannot be executed earlier than the previous batch of transactions. In the process of actually uploading transaction data to the chain, the execution phase takes more time than the collection and consensus phases. This causes each intermediate batch of transactions to wait for the execution of the previous batch of transactions after the consensus is completed. This waiting time (T in Figure 2 represents the waiting time) will determine the efficiency of transaction data on-chain.

Based on the method of the embodiment of this specification, the transactions proposed by each round of consensus are divided into multiple small batches, which can reduce the time-consuming execution of each batch of transactions, that is, reduce the length of T in Figure 2, thereby improving the area Processing efficiency of blockchain transactions.

It should be understood that the above-mentioned first thread, second thread, third thread, fourth thread and fifth thread may belong to different cores of the processor. That is to say, the embodiment of this description can perform the transaction collection operation, consensus operation, and execution operation on the same round of consensus proposals in a multi-core and multi-thread parallel manner.

The above is the introduction to the method in the embodiment of this specification. It should be understood that appropriate changes can also be made without departing from the above-mentioned principles herein, and these changes should also be regarded as the protection scope of the embodiments of this specification.

For example, in the embodiment of this description, since the operation of feeding back the transaction execution result to the client can be executed immediately after the transaction is executed, one thread can be used to execute the transaction execution operation and the feedback operation of the transaction execution result. That is, the fourth thread mentioned above is the third thread mentioned above, and the consensus proposals of round N and round N+1 can present the time slot relationship shown in Figure 3.

For another example, the method in the embodiment of this specification can also perform the execution operation and block writing operation for all batches of transactions proposed in the N-round consensus proposal after all batches of transactions in the N-round consensus proposal have completed consensus . That is, the processing method of the blockchain transaction in the embodiment of this specification can also be shown in Figure 4, including the following steps:

S402. Collect the first batch of transactions in the Nth round consensus proposal of the blockchain, where the Nth round consensus proposal includes multiple batches of transactions.

S404, execute the consensus operation on the first batch of transactions, and if there is a second batch of transactions, execute the collection operation of the second batch of transactions in parallel in batch order, the second batch of transactions is the Nth round of consensus proposals that have not been completed Collected batches of transactions.

S406. If all batches of transactions proposed by the Nth round of consensus have completed the consensus, execute a transaction execution operation on all batches of transactions proposed by the Nth round of consensus.

S408, sending the transaction execution results of all batches of transactions proposed by the Nth round of consensus in the blockchain to perform transaction confirmation on all the batches of transactions proposed by the Nth round of consensus.

S410. After obtaining the transaction confirmations of all the batches of transactions proposed by the Nth round of consensus, perform a block writing operation on all the batches of transactions proposed by the Nth round of consensus.

Fig. 5 is a time slot relationship diagram for the N-th round and the N+1-th round of consensus proposals based on the method shown in Fig. 4 . It should be understood that the execution operations of all batches of transactions proposed by the N-th round of consensus can be performed at least after the execution of all batches of transactions proposed by the N-1 consensus round is completed.

Similarly, the method shown in Figure 4 uses the first thread to collect transactions in batch order for each round of consensus proposals, that is, the first thread does not collect other batches of transactions before collecting one batch of transactions; The round of consensus proposals executes the consensus operations of transactions in batch order, that is, the second thread does not execute the consensus operations of other batches of transactions before executing the consensus operations of one batch of transactions; All batches of transactions are executed uniformly; through the fourth thread, all batches of transactions in each round of consensus proposals are uniformly confirmed; through the fifth thread, all batches of transactions in each round of consensus proposals are uniformly written block operation. Here, the first thread, the second thread, the third thread, the fourth thread, and the fifth thread are threads executed in parallel.

As can be seen from Figure 5, for the method shown in Figure 4:

If there is a second batch of transactions when the transaction execution operation is performed on the first batch of transactions, the collection operation of the second batch of transactions in batch order is executed in parallel.

If all batches of transactions in the Nth round of consensus proposals have been collected when the first batch of transactions is written, then the collection of batches of transactions in the N+1st round of consensus proposals will be performed in batch order .

It can be seen that the method shown in Figure 4 can also execute transaction collection and transaction consensus for each round of consensus proposals in batches. In particular, while the consensus operation is performed on the intermediate batch of transactions proposed by each round of consensus, the collection operation of the next batch of transactions is also performed, so that the processing time of the blockchain transaction can also be shortened in parallel, thereby improving the area. The throughput of the block chain can meet the needs of high-concurrency business scenarios.
