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 mentioned above, the processing flow of the blockchain transaction mainly includes: transaction consensus, transaction execution confirmation and transaction writing. In the prior art, the four phases are executed serially in sequence, that is, after a client of the block chain initiates a transaction, the transaction is executed after the client completes consensus. As such, the client cannot immediately know the execution result of the transaction, and this delay problem is perceived by the client user, and if the delay is serious, the user experience is affected. In view of this problem, this document aims to provide a technical solution for improving the efficiency of confirming the execution result of the blockchain transaction.
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, the consensus node of the block chain executes the consensus operation of the first transaction set in the Nth round of consensus proposition, wherein N is a positive integer.
The first transaction set may include all the transactions requiring consensus in the nth round of consensus proposition, or may include some of the transactions requiring consensus in the nth round of consensus proposition, which is not specifically limited herein.
In this step, if the consensus node is used as the consensus master node of the block chain, the nth consensus proposal needs to be created and sent to the consensus backup node of the block chain. After the consensus backup node obtains the Nth round of consensus proposal, the consensus nodes (including the consensus main node and the consensus backup node) of the blockchain start to perform consensus operation on the first transaction set. Similarly, if the consensus node is a consensus backup node of the blockchain, after receiving the nth round of consensus offer sent by the consensus master node of the blockchain, performing consensus operation on the first transaction set.
And S104, the consensus node executes the transaction execution operation of the first transaction set.
It should be understood that in the embodiments of the present specification, the consensus node does not need the first transaction set to achieve consensus, and can perform the transaction execution operation on the first transaction set.
Specifically, the consensus node may perform the transaction execution operation of the first transaction set in parallel when performing the consensus operation of the first transaction set after the initiation of the nth round of consensus offer. It should be understood that the consensus node performs the consensus operation mainly including: and (4) consensus checking and receiving and sending consensus messages. That is, in parallel, the consensus node can perform the transaction execution operation at least by using the time waiting for receiving the consensus message sent by other consensus nodes, thereby improving the processing efficiency of the blockchain transaction.
And S106, after the execution of the transaction execution operation is finished, the consensus node initiates a transaction execution determination operation on the first transaction set.
It should be understood that the transaction execution determination operation refers to an operation of confirming the transaction execution result. In the process, after the transaction execution operation of the first transaction set is completed, the consensus node sends a transaction execution confirmation message of the first transaction set to other consensus nodes of the block chain, wherein the transaction execution confirmation message carries the hash information of the first transaction set; similarly, when the other consensus nodes complete the transaction execution operation of the first transaction set, the other consensus nodes send a transaction execution confirmation message of the first transaction set to the consensus node in this step.
When the consensus node in this step receives a transaction execution confirmation message carrying the hash information of the same first transaction set sent by 2f other consensus nodes, the transaction execution of the first transaction set can be confirmed (f is the Byzantine fault-tolerant number set for the block chain). It should be understood that after the transaction execution of the first transaction set is confirmed, the transaction execution result in the first transaction set can be fed back to the corresponding client and perceived by the client user in advance.
And S108, after the consensus node agrees on all transaction sets of the N-th consensus proposal and completes the transaction execution confirmation operation, executing block writing operation on all transaction sets of the N-th consensus proposal.
It should be understood that the block writing operation in the conventional serial manner needs to be executed after the confirmation of the transaction execution results of all transaction sets of the nth consensus proposal, and the above steps according to the embodiments of the present invention can complete the transaction execution operation and the transaction execution confirmation operation in advance, so that the block writing operation is executed in advance, thereby reducing the time consumption for chaining the blockchain transaction and improving the transaction processing efficiency of the blockchain.
In addition, in order to further improve the processing efficiency of the blockchain transaction, the consensus node can generate a temporary block of the N-th consensus proposal after the confirmation operation is performed on all transaction sets of the N-th consensus proposal; at this time, if the consensus is not achieved on all transaction sets of the Nth round of consensus proposition, the consensus node waits; if all transaction sets of the N round consensus proposition are agreed upon, the consensus node directly writes the temporary blocks of the N round consensus proposition into the block chain, thereby saving time consumption of the block writing operation.
Therefore, based on the method of the embodiment of the present specification, the consensus node of the block chain can execute the transaction execution operation on the transaction in advance before the consensus operation of the transaction is completed, and initiate the transaction execution determination operation after the transaction execution operation is completed, so that the validation efficiency of transaction finalization is improved, the client user can know the transaction execution result as soon as possible, and the user experience is improved to a certain extent. In addition, the write block operation can be executed earlier in advance of transaction execution confirmation, so that the transaction uplink efficiency of the block chain is improved, the service throughput of the block chain is further improved, and the block chain transaction processing method and the block chain transaction processing system meet the high-concurrency development trend of block chain services in the future.
The method of the embodiments of the present disclosure is described in detail below with reference to practical application scenarios.
In the application scenario, the consensus node of the block chain executes the consensus operation based on a Practical Byzantine Fault Tolerance (PBFT) protocol.
The consensus process of the traditional PBFT protocol mainly comprises the following steps:
pre-preparation stage:
the main consensus node receives a request from a Client and assigns a number to the request, and the consensus main node broadcasts a pre-prepare message to the consensus backup node, wherein the pre-prepare message mainly comprises a view (view) of the current consensus, an abstract (digest) of the consensus main node, block-hash information and the like.
And each consensus backup node checks the information in the pre-preamble message after receiving the pre-preamble message. If the check is successful, the prepare phase is entered directly. If the check fails, the consensus process ends.
The prepare stage:
each of all the consensus backup nodes participating in the consensus checks whether the pre-preamble message is legal or not after receiving the pre-preamble message. If the pre-preparation message is legal, the consensus proposal is determined to be prepared in the replica, the consensus backup node adds the pre-preparation message to the local Log, and sends the preparation message to other consensus backup nodes participating in the consensus.
And a commit stage:
after entering a prepared state, each of all the consensus nodes sends a commit message to other consensus nodes, and adds the commit message sent by the consensus node to a local Log (representing the approval of the consensus node). When a consensus node discovers that there is a quorum (quorum is a set of a certain number of replicas needed to ensure the consistency and fault tolerance requirements of all replica data) grant number assignment, it broadcasts a commit message to all other nodes. And meanwhile, the commit messages from other nodes are received successively, if each node receives 2f commit messages which do not contain the commit messages sent by the node (f is the number of the nodes doing the bad in the alliance chain, and the 2f commit messages do not contain the commit messages sent by the node), the node is named to have a certificate named committed certificate, and the committed state is requested to be reached on the node. Now, only by this one consensus node, it can be concluded that the request has reached the prepended state in one quorum, i.e. all consensus nodes of the same quotum have agreed on the assignment of the number n. When the request initiated by the Client reaches the committed state, the situation that the whole network consensus is achieved is shown.
The above is a flow introduction of the conventional PBFT protocol. In the application scenario, in a consensus stage of executing the PBFT protocol on a certain transaction set, transaction execution operation and transaction execution determination operation on the transaction set are introduced.
Taking the N-th round consensus proposal as an example, on the basis, the consensus master node of the application scenario needs to select the first transaction set from the own transaction pool to initiate the N-th round consensus proposal, and sends the transaction data of the first transaction set to the consensus backup node of the block chain through a Pre-preparation message in a Pre-preparation stage.
It should be noted that, after determining the transaction data of the first transaction set, the consensus node may perform a transaction execution operation on the first transaction set. That is, in the application scenario, the consensus master node may perform the transaction execution operation on the first transaction set at the earliest stage in the Pre-Prepare stage, and the consensus backup node needs to perform the transaction execution operation on the first transaction set at the Prepare stage after obtaining the transaction data of the first transaction set through the Pre-Prepare message.
By the design, each consensus node of the block chain can generate a temporary block of the first transaction set before the Commit stage. In this way, the Commit message may be multiplexed to complete the transaction execution confirmation operation. That is, each consensus node of the block chain sends the hash information of the temporary blocks of the first transaction set to other block chain nodes of the block chain through a Commit message in the Commit phase. And then, if receiving a Commit message which is sent by 2f other consensus nodes and carries the hash information of the temporary block of the same first transaction set, the arbitrary consensus node confirms the transaction execution of the first transaction set.
Here, for convenience of understanding, it is assumed that there are 4 consensus nodes of the blockchain: p1, P2, P3 and P4, wherein P1 is a consensus main node of the N-th consensus proposal, P2, P3 and P4 are consensus backup nodes of the N-th consensus proposal, and only the first transaction set is included in the N-th consensus proposal initiated by P1. As shown in fig. 2, the conventional PBFT-based transaction uplink process may sequentially perform a pre-prepare stage consensus operation, a Commit stage consensus operation, a transaction execution operation/transaction execution confirmation operation (indicated by shaded blocks), and a block write operation (indicated by unfilled blocks) on a first transaction set in a serial manner.
An application scenario of the embodiment of the present disclosure is shown in fig. 3, which is a PBFT protocol-based uplink transaction process. That is, the P1 directly generates a temporary area of the N-th round consensus proposal before performing the consensus operation in the Commit stage of the PBFT protocol, and sends a hash information Commit message carrying the temporary blocks of the N-th round consensus proposal to other consensus nodes in the Commit stage. It should be understood that, since the N-th consensus proposal only includes the first transaction set, the hash information of the temporary block of the N-th consensus proposal is the hash information of the first transaction set, and if the consensus node receives a Commit message carrying the hash information of the temporary block of the same N-th consensus proposal sent by 2f other consensus nodes in the Commit stage, it can confirm the final execution of all transactions in the N-th consensus proposal and directly write the temporary block of the N-th consensus proposal into the block chain.
As can be seen from comparing fig. 2 and fig. 3, the application scenario of the embodiment of the present disclosure can complete the transaction execution operation and the subsequent transaction execution confirmation operation in the consensus phase without introducing additional message overhead.
Of course, the above is an example of how the consensus node performs the transaction execution operation and the transaction execution confirmation operation when only one transaction set is included in the consensus proposition. In addition to fig. 2, the method according to the embodiment of the present invention may also be as shown in fig. 4, where the consensus primary node performs a transaction execution operation with the consensus backup node in the Prepare phase; or as shown in fig. 5, the consensus primary node and the consensus backup node execute the transaction execution operation after the Prepare phase and enter the Commit phase after the transaction execution operation is completed. It should be understood that, regardless of the variations, it is within the scope of the present document to perform transaction execution operations and transaction execution confirmations in parallel on a transaction set, all within the consensus phase of the transaction set.
When the above principle is extended to the nth round of consensus proposing a plurality of transaction sets including the first transaction set, the consensus node may complete the consensus operation, the transaction execution operation and the transaction execution confirmation operation on a plurality of intersections of the nth round of consensus proposing in batches as shown in fig. 6.
Fig. 6 exemplifies that the nth round consensus proposal includes a first intersection, a second transaction set, and a third transaction set. The common identification node is provided with a first CPU thread (which may also be a CPU core, which is not described herein by way of example again) responsible for executing the common identification operation, a second CPU thread responsible for executing the transaction execution operation and the transaction execution confirmation operation, and a third CPU thread responsible for executing the block writing operation, where the first CPU thread, the second CPU thread, and the third CPU thread are parallel to each other.
First, the consensus node executes the consensus operation of the first transaction set through the first CPU thread, and simultaneously executes the transaction execution operation and the transaction execution confirmation operation of the first transaction set through the second CPU thread. After the first transaction set completes consensus and the transaction execution result is confirmed, the consensus node starts to execute the consensus operation of the second transaction set through the first CPU thread, and simultaneously execute the transaction execution operation and the transaction execution confirmation operation of the second transaction set through the second CPU thread. After the second transaction set completes consensus and the transaction execution result is confirmed, the consensus node starts to execute the consensus operation of the third transaction set through the first CPU thread, and simultaneously executes the transaction execution operation and the transaction execution confirmation operation of the third transaction set through the second CPU thread. After the third transaction set completes consensus and the transaction execution result is confirmed, the consensus node starts to execute block writing operation on the first transaction set, the second transaction set and the third transaction set through the third CPU thread regeneration.
Furthermore, if the N-th round consensus proposition includes multiple transaction sets including the first transaction set (still taking the N-th round consensus proposition including the first intersection, the second transaction set and the third transaction set as an example), the consensus node may further set more CPU threads to implement, on the basis that the consensus operation, the transaction execution operation and the transaction execution confirmation operation are completed on multiple intersections of the N-th round consensus proposition in batches, as shown in fig. 7: when the transaction execution operation is executed on the first transaction set, if a second transaction set which is not completed with consensus exists in the Nth round of consensus proposition, the consensus operation is executed on the second transaction set in parallel. Similarly, when executing the transaction execution operation on the second transaction set, if a third transaction set which does not complete consensus exists in the Nth round of consensus proposition, executing the consensus operation on the third transaction set in parallel. It can be seen that, compared with the transaction processing method shown in fig. 6, the transaction processing method shown in fig. 7 further utilizes the advantages of multi-core and multi-thread of the CPU to improve the uplink efficiency of the blockchain transaction in a parallel manner. Here, if the order of execution of the blockchain transactions needs to be ensured, the transaction execution operations of the second transaction set should be executed after the transaction execution operations of the first transaction set are completed, and similarly, the transaction execution operations of the third transaction set should be executed after the transaction execution operations of the second transaction set are completed.
In summary, when the method of the application scenario performs the consensus operation on the first transaction set of the nth consensus proposal, the method also performs the transaction execution operation on the first transaction set in parallel, thereby improving the efficiency of transaction execution confirmation of the first transaction set, enabling the client user to know the transaction execution result as early as possible, and improving the user experience to a certain extent. On the other hand, the concurrence of the consensus operation and the transaction execution operation also shortens the uplink time consumption of the blockchain transaction, which means that the traffic throughput of the blockchain is improved.
In addition, even if the consensus proposal is timed out to trigger the view switching of the block chain (replacing the consensus master node), the consensus node does not waste time to execute the transaction execution operation. This is because the consensus proposed timeout period set by the existing blockchain is typically several seconds to several tens of seconds, and the consensus node has enough time to complete the transaction execution operation during the timeout period.
Of course, if the consensus suggestion timeout ends, the consensus node may also cache the generated temporary block for use in subsequent rounds of consensus suggestions. Here, taking the N-th consensus suggestion timeout as an example, after the N-th consensus suggestion timeout is generated, if the N-th consensus suggestion timeout ends, the consensus node may buffer the temporary block of the first transaction set, and when performing the consensus operation on the transaction set of the N + 1-th consensus suggestion, if the N + 1-th consensus suggestion is consistent with the transaction set of the N-th consensus suggestion (i.e., the consensus node of the N + 1-th consensus suggestion initiates the consensus suggestion of the same transaction set), skip performing the transaction execution operation on the second transaction set, and use the buffered temporary block of the first transaction set as the temporary block of the second transaction set. That is, if the (N + 1) th round of consensus offers to agree, the temporary blocks previously cached in the first transaction set are written into the block chain. Of course, if the N +1 th consensus proposal does not match the transaction set of the nth consensus proposal, the consensus node may choose to delete the temporary block of the cached first transaction set to clear the cache space. The process is suitable for a scene that the consensus proposal is recovered and restarted after the failure occurs in the consensus period by the consensus proposal main node, or the consensus proposal overtime triggers the view switching of the block chain, and the new consensus proposal main node restarts the scene of the consensus proposal for the transaction set of the original consensus proposal.
Corresponding to the transaction processing method shown in fig. 1, an embodiment of the present invention further provides a blockchain node. Fig. 8 is a schematic structural diagram of a block link point 800 according to an embodiment of the present invention, including:
a transaction consensus module 810, which performs consensus operations of the first transaction set in the nth round of consensus offers, where N is a positive integer;
a transaction execution module 820 that executes transaction execution operations of the first set of transactions;
the transaction execution confirmation module 830, after the transaction execution operation is completed, initiates a transaction execution determination operation on the first transaction set;
and a block writing module 840 for performing a block writing operation on all transaction sets of the N-th consensus proposal after all transaction sets of the N-th consensus proposal have been agreed and the transaction execution confirmation operation is completed.
Based on the device of the embodiment of the description, the common identification node of the block chain can execute transaction execution operation on the transaction in advance before the common identification operation of the transaction is completed, and initiates the transaction execution determination operation after the transaction execution operation is completed, so that the transaction finalization confirmation efficiency is improved, a client user can know the transaction execution result as soon as possible, and the user experience is improved to a certain extent. In addition, the write block operation can be executed earlier in advance of transaction execution confirmation, so that the transaction uplink efficiency of the block chain is improved, the service throughput of the block chain is further improved, and the block chain transaction processing method and the block chain transaction processing system meet the high-concurrency development trend of block chain services in the future.
Optionally, the transaction execution confirmation module 830 is specifically configured to: sending a transaction execution confirmation message of the first transaction set to other common identification nodes of the block chain, wherein the transaction execution confirmation message carries hash information of the first transaction set; and receiving transaction execution confirmation messages which are sent by other consensus nodes and carry the hash information of the first transaction set, and confirming the transaction execution of the first transaction set after receiving the transaction execution confirmation messages which are sent by 2f other consensus nodes and carry the same hash information of the first transaction set, wherein f is the Byzantine fault-tolerant quantity set by the block chain.
Optionally, the write block module 840 is specifically configured to: generating a temporary block of the N round consensus proposition after the confirmation operation is performed on all transaction sets of the N round consensus proposition; if no consensus has been reached for all transaction sets of the Nth consensus proposal, the consensus node waits; if consensus has been reached for all transaction sets of the N-th consensus proposal, the consensus node writes the temporary blocks of the N-th consensus proposal into the block chain.
Optionally, the transaction consensus module 810 performs the transaction execution operations of the first transaction set in parallel by the transaction execution module 820 at the same colleague performing the consensus operations of the first transaction set in the N-th round of consensus offers.
By way of exemplary presentation:
the consensus node executes consensus operation based on a practical Byzantine fault-tolerant PBFT protocol; if the consensus node is the consensus master node of the block chain, the transaction execution module 820 executes the transaction execution operation of the first transaction set in parallel when the transaction consensus module 810 executes the consensus operation of the Pre-preparation stage of the PBFT protocol on the first transaction set; if the consensus node is the consensus backup node of the block chain, the transaction executing module 820 executes the transaction executing operation of the first transaction set in parallel when the transaction consensus module 810 executes the consensus operation of the preparation Prepare stage of the PBFT protocol on the first transaction set.
Optionally, the transaction executing module 820 completes the transaction executing operation executed on the first transaction set before the transaction consensus module 810 executes the consensus operation of the guaranteed Commit stage of the PBFT protocol on the first transaction set; the transaction execution confirming module 830, when executing the Commit operation of the Commit stage of the PBFT on the first transaction set, uses a Commit message as a transaction execution confirming message of the first transaction set to send to other consensus nodes of the block chain, where the Commit message sent by the consensus nodes carries hash information of the first transaction set generated by the consensus nodes.
Optionally, if the N-th round consensus suggestion only includes the first transaction set, the consensus node generates a temporary block of the N-th round consensus suggestion before performing a consensus operation in a Commit phase of the PBFT protocol on the first transaction set, where a Commit message sent by the consensus node carries hash information of the temporary block of the N-th round consensus suggestion generated by the consensus node, and the hash information of the temporary block of the N-th round consensus suggestion serves as hash information of the first transaction set.
Optionally, if the N-th round consensus is proposing a plurality of transaction sets including the first transaction set, the consensus node performs consensus operations on the second transaction set in parallel if a second transaction set exists while performing transaction execution operations on the first transaction set, wherein the second transaction set is a transaction set of the N-th round consensus proposition for which consensus has not been completed.
In addition, the block chain node according to the embodiment of the present invention further includes:
a buffer module, configured to buffer the temporary block of the N-th consensus suggestion if the N-th consensus suggestion is over time after the transaction execution module 820 generates the temporary block of the N-th consensus suggestion; correspondingly, when the N +1 th consensus offer is performed, if the N +1 th consensus offer matches the transaction set of the N th consensus offer, the transaction execution module 820 skips the process of performing the transaction execution on the transaction set of the N +1 th consensus offer and uses the temporary block of the N +1 th consensus offer as the temporary block of the N +1 th consensus offer. Of course, if the N +1 th consensus suggestion is inconsistent with the transaction set of the nth consensus suggestion, the buffer module deletes the temporary block that can be removed from the temporary block of the nth consensus suggestion.
