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. In addition, every time a round of views is completed, a block write operation needs to be performed, and excessive block write operations will also have a negative impact on the processing efficiency of blockchain transactions. 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 target transaction set of the blockchain, where the target transaction set includes multiple batches of transactions, and the number of transactions exceeds the upper limit of the number of transactions in one consensus of the blockchain.

It should be noted that this article does not specifically limit the transaction batch division logic of the target transaction set. However, any scheme that divides the transactions in the target transaction set 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 divide all transactions of the target transaction set into batches in an orderly manner according to the corresponding transaction initiation time based on the smart contract set in advance . Or, according to the order of transactions in the consensus proposal, all transactions of the target transaction set are divided into batches.

S104, perform a consensus operation on the first batch of transactions, and if there is a second batch of transactions, perform a collection operation on the second batch of transactions in parallel in batch order, the second batch of transactions is the target transaction set that has not yet been collected Batch 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 of the target transaction set 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 consensus operation on the third batch of transactions in parallel execution of the third batch of transactions, the third batch of transactions is that the target transaction set has been collected and Batch transactions that 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 of the target transaction set 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.

In addition, 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 can also be executed in parallel.

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 batches of transactions in the target transaction set, perform a block write operation on all batches of transactions in the target transaction set.

It should be understood that, in the embodiment of this specification, the blockchain nodes perform consensus operations on the transactions of the target transaction set 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 in the target transaction set can be recorded in one block.

Based on the method in the embodiment of this specification, the block chain node executes transaction collection, transaction consensus, transaction execution and transaction confirmation in batches for the target transaction set with a large amount of data. In particular, while the intermediate batch of transactions executes the consensus operation, it also executes the execution operation of the previous batch of transactions and the collection operation of the next batch of transactions, thereby shortening the processing time of blockchain transactions in a parallel manner. In addition, after all batches of transactions in the target transaction set are confirmed, a block write operation is performed uniformly, thereby improving the processing efficiency of blockchain transactions by reducing the number of block writes. The whole solution can significantly improve the throughput of the blockchain, which can 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, after obtaining the transaction confirmation of all batches of transactions in the target transaction set, the transaction execution results of all batches of transactions in the target transaction set can be uniformly fed back to The corresponding blockchain client.

In practical applications, the feedback strategy for transaction execution results can be determined according to the transaction quantity in the target transaction set. For example, when the number of transactions in the target transaction set 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 target transaction set does not exceed the preset threshold, you can choose to transfer all batches of transactions in the target transaction set to The transaction execution results are uniformly fed back to the corresponding blockchain client.

The processing method in the embodiment of this specification is exemplarily introduced below in combination with actual application scenarios.

As one of the feasible solutions, the method in the embodiment of this specification can process blockchain transactions in batches at the granularity of each round of blockchain views.

Here, it is assumed that the target transaction set in the embodiment of this specification is all transactions in the Nth round view of the blockchain.

The following is a detailed introduction to the principle of continuous processing of transactions in the N-1 round and the N-th round of the method of the embodiment of this specification (the N-th round of view and the N+1-th round of view require at least two blockchain consensuses to complete) Uplink of transaction data).

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 in each round of views 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 views 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 views of round N and round N+1 can present the time slots shown in Figure 2 relation.

It can be seen from Figure 2:

If all batches of transactions in the target transaction set are collected when the consensus operation is performed on the first batch of transactions, the collection operation of batches of transactions in the N+1-th round view is performed in batch order.

If all batches of transactions in the target transaction set are collected when the transaction execution operation is performed on the first batch of transactions, the collection operation of batches of transactions in the N+1-th round view is performed in batch order.

If all batches of transactions in the target transaction set have reached consensus when executing the transaction on the first batch of transactions, execute batches that have been collected but have not yet completed consensus in the N+1 round view in batch order Consensus operation of transactions.

If all batches of transactions in the target transaction set are collected when the first batch of transactions is written, the collection operation of the batches of transactions in the N+1-th round view is performed in batch order.

If all batches of transactions in the target transaction set have reached consensus when writing blocks for the first batch of transactions, execute the batches that have been collected but have not yet completed consensus in the N+1 round of views in batch order Consensus operation of 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, the subsequent batch of transactions in each round of view 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 of each round of views 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 block The processing efficiency of chain 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 views 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 views of round N and round N+1 of the blockchain 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 on all batches of transactions in the N-th round of views in a unified manner after all batches of transactions in the N-th round of views 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 target transaction set of the blockchain, where the target transaction set includes multiple batches of transactions, and the number of transactions exceeds the upper limit of the number of transactions in one consensus of the blockchain.

S404, perform a consensus operation on the first batch of transactions, and perform a collection operation on the second batch of transactions in parallel if there is a second batch of transactions, the second batch of transactions is the target transaction set that has not yet been collected Batch transactions.

S406, if all batches of transactions in the target transaction set have completed the consensus, perform a transaction execution operation on all batches of transactions in the target transaction set.

S408, sending transaction execution results of all batches of transactions in the target transaction set in the blockchain to perform transaction confirmation on all batches of transactions in the target transaction set.

S410. After obtaining the transaction confirmations of all batches of transactions in the target transaction set, perform a block write operation on all batches of transactions in the target transaction set.

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

Similarly, the method shown in Figure 4 uses the first thread to collect transactions in batch order for each round of views, that is, the first thread does not collect other batches of transactions before collecting a batch of transactions; The view 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; through the third thread, all batches in each round of view The transactions are executed in a unified manner; through the fourth thread, all batches of transactions in each round of views are uniformly confirmed; through the fifth thread, all batches of transactions in each round of views are uniformly written into blocks. 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 all batches of transactions in the view of the Nth round are collected when the consensus operation is performed on the first batch of transactions, the collection operation of the batches of transactions in the view of the N+1th round 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 collection operation of the second batch of transactions in batch order is executed in parallel.

If all batches of transactions in the view of the Nth round 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 view of the N+1th round is performed in batch order.

If all batches of transactions in the Nth round of views have reached consensus when the transaction execution operation is performed on the first batch of transactions, the batches that have been collected but have not yet completed consensus in the N+1th round of views are executed in batch order. Consensus operation of the transaction.

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

If all batches of transactions in the Nth round of views have reached a consensus when writing blocks for the first batch of transactions, execute the batches that have been collected but have not yet completed consensus in the N+1th round of views in batch order. Consensus operation of the transaction.

It can be seen that the method shown in FIG. 4 can also perform transaction collection and transaction consensus on the target transaction set in batches. In particular, while the consensus operation is performed on the intermediate batch of transactions, the collection operation of the next batch of transactions is also performed, so that the processing time of blockchain transactions can also be shortened in parallel. In addition, after all batches of transactions in the target transaction set are confirmed, a block write operation is performed uniformly, thereby improving the processing efficiency of blockchain transactions by reducing the number of block writes. The whole solution can significantly improve the throughput of the blockchain, which can meet the needs of high-concurrency business scenarios.

It should be understood that the methods in the embodiments of this specification are not limited to taking each round view of the blockchain as the execution granularity. However, when the block chain accumulates to a transaction set that cannot be completed on the chain through a consensus, the method of the embodiment of this specification can be used to realize the data on-chain that only initiates a block writing operation once.

In addition, corresponding to the processing method shown in FIG. 1 above, the embodiment of this specification also provides a blockchain node. Fig. 6 is a schematic structural diagram of a blockchain node 600 according to an embodiment of this specification, including:

The first transaction collection module 610 collects the first batch of transactions in the target transaction set of the block chain, the target transaction set includes multiple batches of transactions, and the number of transactions exceeds the upper limit of the number of transactions agreed upon by the block chain at one time .

The first transaction consensus module 620 performs a consensus operation on the first batch of transactions, and if there is a second batch of transactions, executes the collection operation of the second batch of transactions in batch order in parallel, wherein the The second batch of transactions is a batch of transactions for which the target transaction set has not yet been collected.

The first transaction execution module 630 performs transaction execution operations on the first batch of transactions, and if there is a third batch of transactions in parallel, executes a consensus operation on the third batch of transactions in batch order, wherein the The third batch of transactions is a batch of transactions for which the target transaction set has been collected and consensus has not yet been completed.

The first transaction confirmation module 640 sends the transaction execution result of the first batch of transactions in the block chain to perform transaction confirmation on the first batch of transactions.

The first transaction block writing module 650 executes a block writing operation on all batches of transactions in the target transaction set after obtaining the transaction confirmations of all batches of transactions in the target transaction set.

The block chain node in the embodiment of this specification executes transaction collection, transaction consensus, transaction execution, and transaction confirmation in batches for a target transaction set with a large amount of data. In particular, while the intermediate batch of transactions executes the consensus operation, it also executes the execution operation of the previous batch of transactions and the collection operation of the next batch of transactions, thereby shortening the processing time of blockchain transactions in a parallel manner. In addition, after all batches of transactions in the target transaction set are confirmed, a block write operation is performed uniformly, thereby improving the processing efficiency of blockchain transactions by reducing the number of block writes. The whole solution can significantly improve the throughput of the blockchain, which can meet the needs of high-concurrency business scenarios.

Optionally, if the second batch of transactions exists when the transaction execution operation is performed on the first batch of transactions, the first transaction execution module 630 simultaneously executes the second batch of transactions in batch order The collection operation for the transaction.

Optionally, the target transaction set is all transactions in the Nth round view of the blockchain, where N is a positive integer.
