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.

As previously mentioned, the blockchain currently accomplishes the four operations of transaction collection, consensus, execution and block writing in a serial manner, which results in relatively inefficient processing of blockchain transactions and limits the throughput of blockchain transactions. As block chains become more popular with various industries, traffic volume may also increase explosively. Obviously, the current transaction processing mode is difficult to be applied to the scene with high subsequent business. To address this issue, this document aims to provide a technical solution capable of improving the efficiency of processing blockchain transactions.

Fig. 1 is a flowchart illustrating a processing method of blockchain transactions according to an embodiment of the present disclosure. The method shown in fig. 1 may be performed by the following corresponding block link points, comprising the steps of:

s102, collecting the first batch transaction in the N-th round of consensus suggestions of the block chain, wherein the N-th round of consensus suggestions comprises a plurality of batch transactions, and N is a positive integer.

It should be noted that the transaction lot dividing logic of the nth consensus proposal is not specifically limited herein. However, any scheme that divides the transaction in the N-th consensus proposal into a plurality of batches shall fall within the scope of the embodiments of the present disclosure.

By way of exemplary presentation: in this embodiment, each block chain link point of the block chain may uniformly perform ordered batch division on all transactions proposed by the N-th round of consensus according to the corresponding transaction initiation time based on an intelligent contract set in advance. Or, according to the transaction sequence in the N round of consensus suggestions, carrying out batch division on all transactions in the N round of consensus suggestions.

S104, executing the consensus operation on the first batch of transactions, and if a second batch of transactions exists, executing the collection operation on the second batch of transactions in batch sequence in parallel, wherein the second batch of transactions propose the batch transactions which are not completed for the Nth round of consensus.

It should be understood that the batch transactions for which collection has not been completed in this step may include batch transactions for which collection has not been initiated, or batch transactions for which collection has been initiated but not completed. The batch order is the batch division order described above in S102.

In the embodiment of the present specification, the block chain node collects the N-th round of the transaction of the consensus proposal in batch. After the collection of the target batch transaction is completed, the following steps can be executed simultaneously: the consensus execution operation of the target batch transaction and the collection operation of the next batch transaction corresponding to the target batch transaction. That is, the second batch transaction in this step is the next batch transaction of the first batch transaction.

S106, carrying out transaction execution operation on the first batch of transactions, and if a third batch of transactions exists, executing consensus operation on the third batch of transactions according to the batch sequence, wherein the third batch of transactions is batch transactions of which the Nth round consensus offers are collected and not completed.

It should be understood that the batch transaction of not completed consensus in this step may include batch transactions that have not initiated consensus, or batch transactions that have initiated consensus but have not completed consensus.

Similarly, in the embodiment of the present specification, the block link point batch performs the consensus operation on the N-th round of the transaction proposed by the consensus. After the consensus operation of the target batch transaction is completed, the following steps can be executed simultaneously: the execution operation of the target batch transaction and the consensus operation of the next batch transaction corresponding to the target batch transaction. That is, the third batch transaction in this step is the next batch transaction of the second batch transaction.

And S108, sending the transaction execution result of the first batch of transactions in the block chain so as to carry out transaction confirmation on the first batch of transactions.

Specifically, the blockchain link node as the execution subject of this step may send a transaction confirmation request of the transaction execution result of the first batch of transactions to other blockchain nodes of the blockchain; and then if transaction confirmation feedback sent by 2f other block chain nodes is received, confirming that the transaction confirmation of the first batch of transactions is obtained. Wherein f is the maximum number of abnormal common identification nodes allowed by the block chain.

S110, after the transaction confirmation of all the batch transactions of the Nth round of consensus suggestion is obtained, the block writing operation is executed on all the batch transactions of the Nth round of consensus suggestion.

It should be understood that in the embodiment of the present specification, the block link point performs the consensus operation on the transaction of the nth consensus proposal in batches, but may eventually perform the block writing operation only once. That is, in the embodiment of the present specification, all batch transactions of the nth consensus proposal can be recorded through one block.

Based on the methods of embodiments herein, block link points may perform tractions, trade consensus, trade execution, and trade validation on each round of consensus offers in batches. Particularly, when the consensus operation is executed on each round of the intermediate batch transaction proposed by the consensus, the execution operation of the previous batch transaction and the collection operation of the next batch transaction are also executed, so that the processing time of the block chain transaction is shortened in a parallel mode, the throughput of the block chain is further improved, and the requirement of a high-service concurrency scene is met.

In addition, after the transaction confirmation of the first batch of transactions is obtained, the transaction execution result of the first batch of transactions can be fed back to the corresponding block chain client. That is to say, in the method according to the embodiment of the present disclosure, after the transaction execution is completed and the transaction is confirmed in each batch of transactions, the blockchain link point may immediately feed back the transaction execution to the blockchain client, so that the transaction confirmation delay at the blockchain client side is significantly reduced, and the user experience is further improved.

Alternatively, in order to reduce the resource overhead of interaction with the blockchain client side, after the transaction confirmation of all batch transactions of the nth round of consensus offers is obtained, the transaction execution results of all batch transactions of the nth round of consensus offers may be uniformly fed back to the corresponding blockchain client sides.

In practical application, a feedback strategy of the transaction execution result can be decided according to the transaction number in the N-th round consensus suggestion. For example, when the transaction amount in the nth round of consensus offers exceeds a preset threshold, the blockchain client may be selected to immediately feed back the transaction execution result after the transaction execution is completed and the transaction is confirmed in each batch of transactions. Similarly, when the transaction amount in the nth round of consensus offers does not exceed the preset threshold, the transaction execution results of all the batch transactions in the nth round of consensus offers can be uniformly fed back to the corresponding blockchain client after the transaction execution of all the batch transactions in the nth round of consensus offers is completed and the transaction confirmation is obtained.

Further, it should also be understood that the method of embodiments of the present specification can continuously process multiple rounds of consensus-proposed transactions.

The working principle is described in detail below by taking as an example the case that the method of the embodiment of the present specification continuously processes the transactions in the consensus proposals of the nth round and the (N + 1) th round.

Referring to fig. 2, the method of the embodiment of the present specification may set a first thread, a second thread, a third thread, a fourth thread, and a fifth thread that are executed in parallel with each other to respectively correspond to five operations of performing collection, consensus, transaction execution, transaction confirmation, and block writing of a blockchain transaction.

The first thread is used for collecting transactions according to batches, namely the first thread does not collect other batches of transactions before one batch of transactions is collected; the second thread is used for executing the consensus operation of the transactions in batches, namely the second thread does not execute the consensus operation of other batches of transactions before executing the consensus operation of one batch of transactions; the third thread is used for executing the execution operation of the transaction in batches, namely executing the execution operation of other batch transactions before the execution operation of one batch transaction is executed. The fourth thread performs transaction confirmation by batch, namely, transaction confirmation of other batch transactions is not performed before transaction confirmation of one batch transaction is performed. And the fifth thread executes the block writing operation uniformly after all batch transactions of each round of consensus proposal are confirmed.

The first batch transaction described above is taken as an example. After the first thread collects the first batch of transactions, the second thread is informed to carry out consensus operation on the first batch of transactions; after the second thread finishes executing the consensus operation of the first batch of transactions, informing the third thread to execute the execution operation on the first batch of transactions; and after the third thread finishes the execution operation of the first batch of transaction, the fourth thread is informed to carry out transaction confirmation on the first batch of transaction.

Taking the example that the consensus proposals of the Nth round and the (N + 1) th round are divided into three batch transactions, the consensus proposals of the Nth round and the (N + 1) th round can present the time slot relationship shown in FIG. 2 by using the working principle of the thread.

As can be seen from fig. 2:

if all the batch transactions in the N round of consensus propositions are collected when the consensus operation is performed on the first batch transactions, the collection operation of the batch transactions in the (N + 1) round of consensus propositions in the sequence of batches is performed.

And if a second batch of transactions exists when the transaction execution operation is carried out on the first batch of transactions, executing the collection operation of the second batch of transactions in parallel according to the batch sequence.

If all the batch transactions in the N round of consensus suggestions are collected when the transaction execution operation is performed on the first batch transactions, the collection operation of the batch transactions in the (N + 1) th round of consensus suggestions according to the sequence of batches is performed.

If all the batch transactions in the N round of consensus propositions are known to be completed when the transaction execution operation is performed on the first batch transactions, the consensus operation of the collected but not yet known batch transactions in the (N + 1) round of consensus propositions according to the sequence of batches is performed.

And if all the batch transactions in the N round of consensus suggestions are collected when the first batch transactions are subjected to block writing operation, performing collection operation on the batch transactions in the (N + 1) th round of consensus suggestions according to the sequence of batches.

If all the batch transactions in the N round of consensus propositions are known to be completed when the block writing operation is performed on the first batch transactions, the consensus operation of the collected but not yet known batch transactions in the (N + 1) round of consensus propositions is performed according to the sequence of batches.

It will also be appreciated that it is also important to ensure the order in which transactions are executed. Assume that in a transaction scenario, user A needs to send 10000 dollars to user B, and then user B sends 5000 dollars to user C. Assuming that the initial balance of user B is 3000, if the transaction is not performed in sequence, i.e. user B remits 5000 yuan to user C and user a remits 10000 yuan to user B, then the problem of failure of remittance from user B to user C occurs.

Thus, to avoid such transaction logic problems, each round of consensus offers that a subsequent transaction cannot be executed earlier than a previous transaction. In the actual uplink process of transaction data, the time consumption of the execution phase is greater than that of the collection phase and the consensus phase. This results in that after the consensus is completed, each intermediate transaction needs to wait for the previous transaction to complete, and the waiting time (T in fig. 2 indicates the waiting time) determines the uplink efficiency of the transaction data.

The method based on the embodiment of the present specification divides each round of the transaction of the consensus proposition into a plurality of small batches, which can reduce the time consumption of each batch of transaction in execution, that is, reduce the length of T in fig. 2, thereby improving the processing efficiency of the blockchain transaction.

It should be understood that the first, second, third, fourth, and fifth threads described above may belong to different cores of a processor. That is, the illustrative embodiments may perform the collect, consensus, and execute operations of a transaction for the same round of consensus offers in a multi-core, multi-threaded parallel manner.

The above is a description of the method of the embodiments of the present specification. It will be appreciated that appropriate modifications may be made without departing from the principles outlined herein, and such modifications are intended to be included within the scope of the embodiments herein.

For example, in this embodiment, since the operation of the transaction execution result feedback client may be executed immediately after the transaction is executed, one thread may be used to execute the transaction execution operation and the transaction execution result feedback operation. That is, the fourth thread described above is the third thread described above, and the consensus proposals of the nth and N +1 th rounds can exhibit the time slot relationship shown in fig. 3.

For another example, the method of the embodiment of the present specification may further perform the execution operation and the block writing operation on all the batch transactions of the nth round consensus suggestion after all the batch transactions of the nth round consensus suggestion have completed consensus. That is, the processing method for blockchain transaction in the embodiment of the present specification may further include, as shown in fig. 4, the following steps:

s402, collecting the first batch transactions in the N round of consensus suggestions of the block chain, wherein the N round of consensus suggestions comprises a plurality of batch transactions.

S404, executing the consensus operation on the first batch of transactions, and if a second batch of transactions exists, executing the collection operation on the second batch of transactions in batch sequence in parallel, wherein the second batch of transactions propose the batch transactions which are not completed for the Nth round of consensus.

S406, if all the batch transactions of the Nth round of consensus proposition are completed, the transaction execution operation is performed on all the batch transactions of the Nth round of consensus proposition.

And S408, sending the transaction execution results of all the batch transactions of the N-th round of consensus and offer in the blockchain to perform transaction confirmation on all the batch transactions of the N-th round of consensus and offer.

S410, after the transaction confirmation of all the batch transactions of the Nth round consensus proposal is obtained, the block writing operation is executed on all the batch transactions of the Nth round consensus proposal.

Fig. 5 is a time slot relationship diagram for the N-th and N + 1-th rounds of consensus proposals based on the method shown in fig. 4. It should be understood that the execution of all batch transactions of the N-th consensus proposal is performed at least after the execution of all batch transactions of the N-1 th consensus proposal is completed.

Similarly, the method shown in FIG. 4 collects transactions in batch order for each round of consensus offers through the first thread, i.e., the first thread does not collect other batch transactions until one batch transaction is collected; the consensus operation of the transactions is executed according to the batch sequence by the two threads for each round of consensus proposal, namely the second thread does not execute the consensus operation of other batches of transactions before executing the consensus operation of one batch of transactions; uniformly performing transaction execution operation on all batch transactions in each round of consensus proposition through a third thread; executing transaction confirmation on all batch transactions in each round of consensus suggestions in a unified way through a fourth thread; and uniformly writing the blocks of all batch transactions in each round of consensus proposition through the fifth thread. Here, the first thread, the second thread, the third thread, and the fourth and fifth threads are threads that are executed in parallel.

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

if all batch transactions in the N round of consensus propositions are collected when the consensus operation is performed on the first batch transactions, the collection operation of the batch transactions in the (N + 1) th round of consensus proposition in the order of batches is performed.

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

And if all the batch transactions in the N round of consensus suggestions are collected when the block writing operation is carried out on the first batch transactions, executing the collection operation of the batch transactions in the (N + 1) th round of consensus suggestions according to the sequence of batches.

It can be seen that the method shown in fig. 4 can also perform transaction collection and transaction consensus for each round of consensus suggestions in batches. Particularly, when the consensus operation is executed on the intermediate batch transaction of each round of consensus proposal, the collection operation of the next batch transaction is also executed, so that the processing time of the block chain transaction can be shortened in a parallel mode, the throughput of the block chain is further improved, and the requirement of a high-service concurrency scene is met.

In addition, corresponding to the processing method shown in fig. 1, an embodiment of the present specification further provides a blockchain node. Fig. 6 is a schematic structural diagram of a block chain node 600 according to an embodiment of the present specification, including:

Specifically, while executing the consensus operation on the intermediate batch transaction, the execution operation of the previous batch transaction and the collection operation of the next batch transaction are also executed, so that the processing time of the block chain transaction is shortened in a parallel manner, the throughput of the block chain is further improved, and the requirement of a high-business concurrency scene is met.

The first transaction block writing module 650 performs block writing operations on all batch transactions in the nth round consensus proposition through a fifth thread.
