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 total transaction in the transaction pool of the current node is synchronized to other common nodes by broadcasting between the common nodes of the block chain. The broadcast synchronization method can cause the traffic to be sent redundantly, thereby causing the waste of bandwidth resources.
For example, the transaction pool of the consensus node a has transactions 1, 2, the transaction pool of the consensus node B has transactions 2, 3, and the transaction pool of the consensus node C has transaction 4. Regardless of the addition of new transactions and the removal of old transactions, after the first round of transaction synchronization, consensus node a broadcasts transactions 1, 2 to consensus node B, C, consensus node B broadcasts transactions 2, 3 to consensus node A, C, and consensus node C broadcasts transaction 4 to consensus node A, B. It can be seen therein that the first round of synchronization results in a redundant transmission of transaction 2.
After the first round of synchronization, the respective transaction pools of the consensus node A, B, C store transactions 1, 2, 3, and 4. Thus, in performing the second round of synchronization, the consensus node A, B, C will send all transactions 1, 2, 3, 4 in the respective transaction pools redundantly.
It can be seen that, in the conventional transaction synchronization mode, the larger the scale of the consensus node is, the larger the transaction data is, the more serious the phenomenon of bandwidth resource waste is, so that the consensus computing power of the block chain is greatly reduced, and the execution efficiency of the block chain service is finally affected.
Therefore, the technical scheme capable of improving the waste of bandwidth resources caused by synchronous transaction between the consensus nodes is provided.
Fig. 1 is a flowchart illustrating a block chain consensus method according to an embodiment of the present disclosure. The method shown in fig. 1 may be performed by corresponding hardware below, comprising the steps of:
and S102, executing view switching operation by a target consensus node of the block chain, wherein the target consensus node is a consensus backup node after executing the view switching operation.
It should be understood that each common node of the blockchain corresponds to a view number. The blockchain typically switches views periodically based on certain rules (e.g., polling), and performs view switching operations corresponding to the common nodes. And for the target consensus node, if the block chain is switched to the view corresponding to the view number of the node, the target consensus node is used as a consensus main node, otherwise, the target consensus node is used as a consensus backup node. Based on the view switching mechanism, all the consensus nodes of the block chain have certain chance to become consensus master nodes to initiate consensus suggestions (consensus backup nodes cannot initiate consensus suggestions), so that decentralization is achieved to a certain degree.
And S104, the target consensus node directionally sends the transaction in the transaction pool of the target consensus node to the consensus main node of the block chain.
It should be understood that, in the embodiment of the present specification, the target consensus node sends the transaction direction in the transaction pool of the target consensus node to the consensus master node of the block chain may represent that: the consensus backup node only synchronously transacts to the consensus main node, namely any consensus backup node does not add new transaction to the transaction pool of the node through other consensus backup nodes.
Here, when the target consensus node is used as the consensus backup node, a new transaction initiated by the blockchain client may be acquired and added to the transaction pool of the target consensus node. On this basis, to achieve smaller bandwidth overhead, as a possible but unnecessary scheme, when the target consensus node is used as a consensus backup node, only the transaction initiated by the blockchain client is added to the transaction pool of the target consensus node, that is, only the bandwidth resource is occupied to receive the transaction directly sent from the blockchain client. Of course, the target consensus node may not reject transactions received by other means, but does not process them.
And S106, the consensus main node of the block chain carries out validity verification on the received transaction and stores the transaction passing the verification into a transaction pool of the node.
The validity verification in this step may refer to verification that an existing blockchain consensus node needs to perform before adding a transaction to the transaction pool. Since the embodiments of the present specification do not relate to the improvement in this respect, detailed description is omitted.
And S108, the consensus master node initiates a consensus proposal based on the transaction in the transaction pool of the node.
In this step, the consensus master node selects at least a portion of the transaction initiation consensus offer from the transaction pool of the node, where the selected transaction initiation consensus offer may include a transaction provided by the target node. The transaction achieving the consensus is generated into a block by each consensus node for storage, so as to realize the uplink of transaction data.
It should be appreciated that in the consensus mechanism for the active-standby distinction of consensus nodes, only the consensus master node of the blockchain can initiate a consensus proposal for the transaction. Based on the method of the embodiment of the specification, the consensus backup node of the block chain only orients synchronous transaction to the consensus main node, and bandwidth overhead can be effectively saved. And if the block chain is replaced with the consensus main node subsequently, the consensus backup node carries out synchronous transaction again to a new consensus main node. In addition, the directional synchronization mode can effectively reduce the redundant transmission of transactions, thereby improving the problem of bandwidth resource waste and avoiding the problem of reduced common identification power caused by overhigh bandwidth occupation of a block chain system.
Specifically, in this embodiment, when the target consensus node is a consensus backup node, the transaction sent to the consensus master node of the blockchain in the transaction pool of the target consensus node may be marked. Correspondingly, in the above S104, the target consensus node sends the unmarked transaction direction in the transaction pool of the node to the consensus master node of the block chain. That is, if the blockchain does not switch views to replace the consensus master node, the target consensus node (consensus backup node) does not synchronize repeated transactions to the consensus master node.
In addition, on the basis, after the view switching operation is performed by the target consensus node, the mark of the transaction in the transaction pool of the target consensus node can be cleared. It should be appreciated that the new consensus master node is replaced after the view is switched in the blockchain, and when the target consensus master node clears the mark and then performs the above step S104, the transaction that was originally sent to the old consensus master node but not sent to the new consensus master node may be sent to the new consensus master node.
The following describes in detail the consensus method of the examples of the present specification.
In the consensus method of the embodiments of the present specification, transactions in the target consensus node transaction pool are mainly classified into two types. One is the transaction of the target consensus node, and the transaction is directly initiated to the target consensus node after the block chain client enters the target consensus node; the other type is the transaction of other consensus nodes, which is initiated by other blockchain clients accessing other consensus nodes and needs to be synchronized by other consensus nodes (consensus backup nodes) after the target node is used as a consensus master node.
The process of executing the consensus method with the target consensus node as the initial consensus backup node as an example is shown in fig. 2, and includes:
and the target consensus node sends the own transaction in the transaction pool of the node to the current consensus main node of the block chain. Here, the target consensus node ignores transactions belonging to other consensus nodes in the transaction pool of the node.
Meanwhile, the target consensus node also receives a new transaction initiated by the blockchain client, verifies the validity of the new transaction initiated by the blockchain client, and if the verification is passed, adds the new transaction into a transaction pool of the target consensus node. Here, the new transaction initiated by the target consensus node adding blockchain client belongs to a completely independent flow, and is not limited by other steps and main and standby.
And then, initiating a master change by the block chain switching view, and executing view switching operation by the target consensus node.
If the target consensus node is still the consensus backup node after executing the view switching operation, all transactions belonging to the target consensus node in the transaction pool of the target consensus node are sent to a new consensus master node of the block chain, and the sending of the transactions comprises the following steps: the transaction is sent to the previous round of consensus master node and, in addition, a new transaction is added to the node's transaction pool by the blockchain client.
And if the target consensus node is the consensus main node after executing the view switching operation, receiving the transactions sent by the consensus backup node and the blockchain client, carrying out validity verification on the received transactions, and storing the verified transactions into a transaction pool of the target consensus node.
Thereafter, if a consensus execution condition is triggered, the target consensus node initiates a consensus proposal based on the transactions in the transaction pool of the node. Here, the transaction in which the consensus proposition is initiated is not limited to the source, and may be a transaction of the target consensus node and other consensus nodes.
Obviously, based on the directional synchronization mode in the embodiment of the present specification, the consensus backup node selects whether to send the stock transactions to the new consensus master node according to whether the consensus master node is switched, which not only reduces the use of network bandwidth, but also ensures the success rate of the packaged transactions. The throughput of the block chain is improved linearly.
The foregoing is an exemplary description of the method of embodiments of the present invention. Suitable variations may be made without departing from the principles described herein, and such variations are to be considered within the scope of the embodiments of the invention.
Further, it should be understood that, in the method of the embodiment of the present specification, if the target consensus node is a consensus backup node after performing the view switching operation, the following steps are performed: and sending the transaction in the transaction pool of the node to the consensus main node of the block chain, so that the consensus main node of the block chain carries out validity verification on the received transaction, and stores the transaction passing the verification into the transaction pool of the node, thereby initiating a consensus proposal based on the transaction in the transaction pool of the node.
Correspondingly, if the target consensus node is the consensus master node after the view switching operation is performed, the following steps are performed: receiving a transaction sent by a consensus backup node of the block chain and a block chain client; carrying out validity verification on the received transaction, and storing the transaction passing the verification into a transaction pool of the node; and initiating a consensus proposal based on the transaction in the transaction pool of the node.
In addition, corresponding to the consensus method shown in fig. 1, an embodiment of the present invention further provides a consensus node of a block chain. Fig. 3 is a schematic structural diagram of a consensus node 300 according to an embodiment of the present invention, including:
and the view switching module 310 performs a view switching operation of the consensus node.
A sending module 320, configured to send the transaction orientation in the transaction pool of the consensus node to the consensus master node of the block chain if the view switching operation makes the consensus node serve as a consensus backup node.
The receiving module 330 is configured to receive a transaction sent by the consensus backup node of the blockchain and the blockchain client if the view switching operation makes the consensus node serve as a consensus master node.
And a synchronization module 340, configured to, if the view switching operation makes the consensus node serve as a consensus master node, perform validity verification on the transaction received by the receiving module, and store the transaction passing the verification in a transaction pool of the consensus node.
A consensus module 350, if the view switching operation makes the consensus node a consensus master node, initiating a consensus proposal based on transactions in a transaction pool of the consensus node.
In the consensus mechanism for the main-standby distinction of the consensus node, only the consensus master node of the block chain can initiate a consensus proposal for a transaction. After the view switching operation is performed, if the consensus node is a consensus backup node, only the synchronous transaction is directed to the consensus master node, so that bandwidth overhead is effectively saved. And if the block chain changes the consensus main node, the transaction is synchronized again to a new consensus main node. In addition, the directional synchronization mode can effectively reduce the redundant transmission of transactions, thereby improving the problem of bandwidth resource waste and avoiding the problem of reduced common identification power caused by overhigh bandwidth occupation of a block chain system.
Optionally, the sending module 320 sends only the transaction orientation directly obtained from the blockchain client in the transaction pool of the consensus node to the consensus master node of the blockchain.
Optionally, when the consensus node serves as a consensus backup node, the sending module 320 marks the transaction that has been sent to the consensus main node of the block chain in the transaction pool of the consensus node, and directionally sends the unmarked transaction in the transaction pool of the node to the consensus main node of the block chain.
On the basis of the above, the sending module 320 may also clear the mark of the transaction in the transaction pool of the consensus node after the view switching module 310 completes the view switching operation.
Optionally, when the consensus node serves as a consensus backup node, the synchronization module 340 only adds the transaction initiated by the blockchain client to the transaction pool of the node.
Obviously, the consensus node of the embodiment of the present specification may be an execution subject of the consensus method shown in fig. 1, and thus can implement the functions of the consensus method implemented in fig. 1 and fig. 2. Since the principle is the same, the detailed description is omitted here.
