Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a block processing method according to an embodiment of the present invention. The embodiment of the present invention provides a block processing method for solving the above technical problems in the prior art, and the method specifically includes the following steps:
As shown in fig. 3, the master node 1, the master node 2, the master node 3, and the master node 4 are blockchain nodes in a blockchain network, and the master node 1, the master node 2, the master node 3, and the master node 4 may specifically be mining nodes in the blockchain network, where the mining nodes may be used to store transaction information generated by transaction nodes in the blockchain network. It is to be understood that the blockchain network is not limited to include mining nodes, trading nodes, and may include other participating nodes. In this embodiment, not all participating nodes record transaction information, but transaction information is recorded mainly by the mining node in the blockchain network, and the transaction node in the blockchain network can directly send the transaction information to the mining node without broadcasting into the blockchain network.
Optionally, the master node 1, the master node 2, the master node 3, and the master node 4 may broadcast respective identification information and an IP address to the blockchain network at an initial stage of registering in the blockchain network, for example, the master node 1 broadcasts the identification information and the IP address of the master node 1 to the blockchain network at the initial stage of registering in the blockchain network, and after receiving the identification information and the IP address of the master node 1, the master node 2, the master node 3, and the master node 4 may establish a connection with the master node 1 according to the identification information and the IP address of the master node 1, specifically, after receiving the identification information and the IP address of the master node 1, the master node 2, the master node 3, and the master node 4 send a connection request to the master node 1.
Optionally, the broadcasting, by the master node, the identification information and the IP address of the master node to the blockchain network includes: and the main node broadcasts the identification information, the IP address and the identity information of the main node to the block chain network, wherein the identity information is used for identifying the main node as a mining node.
Specifically, when the master node 1, the master node 2, the master node 3, and the master node 4 are in an initial stage of registering in the blockchain network, the respective identification information and the IP address are broadcast to the blockchain network, and at the same time, the respective identity information is also broadcast to the blockchain network, for example, the identity information of the master node 1 is used to indicate that the master node 1 is a mining node, and the transaction nodes in the blockchain network can send the respective transaction information to the mining node. Similarly, the identity information of the host node 2 is used to indicate that the host node 2 is a mining node, and the transaction nodes in the blockchain network can send respective transaction information to the mining node; the identity information of the main node 3 is used for indicating that the main node 3 is a mining node, and the transaction nodes in the blockchain network can send respective transaction information to the mining node; the identity information of the master node 4 is used to indicate that the master node 4 is a mining node, and the transaction nodes in the blockchain network can send respective transaction information to the mining node.
Optionally, the identification information, the IP address broadcast and/or the identity information respectively sent by the master node 1, the master node 2, the master node 3 and the master node 4 may be stored in the same block or different blocks in the blockchain network. In addition, if at least one of the master node 1, the master node 2, the master node 3, and the master node 4 changes the IP address, the master node may also broadcast its identification information and the updated IP address to the blockchain network, so as to update its own IP address.
For example, the master node 1 may receive connection requests transmitted by the master nodes 2, 3, and 4, respectively. The master node 2 may receive connection requests respectively sent by the master node 1, the master node 3, and the master node 4. The master node 3 may receive connection requests respectively sent by the master node 1, the master node 2, and the master node 4. The master node 4 may receive connection requests respectively sent by the master node 1, the master node 2, and the master node 3.
And 203, the main node establishes connection with other main nodes according to the connection request.
Optionally, the host node 1 may establish connections with the host node 2, the host node 3, and the host node 4 respectively according to connection requests sent by the host node 2, the host node 3, and the host node 4 respectively.
Similarly, the master node 2 may establish connection with the master node 1, the master node 3, and the master node 4 respectively according to the connection requests sent by the master node 1, the master node 3, and the master node 4 respectively.
Similarly, the master node 3 may establish connection with the master node 1, the master node 2, and the master node 4 respectively according to the connection requests sent by the master node 1, the master node 2, and the master node 4 respectively.
Similarly, the master node 4 may establish connection with the master node 1, the master node 2, and the master node 3 respectively according to the connection requests sent by the master node 1, the master node 2, and the master node 3 respectively.
Optionally, the establishing, by the master node, a connection with the other master nodes according to the connection request includes: and the main node establishes Transmission Control Protocol (TCP) connection or User Datagram Protocol (UDP) connection with other main nodes according to the connection request. For example, the master node 1 may establish a Transmission Control Protocol (TCP) connection or a User Datagram Protocol (UDP) connection with the master node 2, the master node 3, and the master node 4 according to connection requests respectively sent by the master node 2, the master node 3, and the master node 4.
Similarly, the master node 2 may establish a TCP connection or a UDP connection with the master node 1, the master node 3, and the master node 4 according to the connection requests respectively sent by the master node 1, the master node 3, and the master node 4.
Similarly, the master node 3 may establish a TCP connection or a UDP connection with the master node 1, the master node 2, and the master node 4 according to the connection requests respectively sent by the master node 1, the master node 2, and the master node 4.
Similarly, the master node 4 may establish a TCP connection or a UDP connection with the master node 1, the master node 2, and the master node 3 according to the connection requests respectively sent by the master node 1, the master node 2, and the master node 3.
Optionally, the master node and the other master nodes form a peer-to-peer network. As shown in fig. 3, the master node 1 may form a Peer-to-Peer network, i.e., a fully connected network of (Peer to Peer, P2P) with the master node 2, the master node 3, and the master node 4.
That is, a fully-connected network of P2P is established between the mining nodes, and the master nodes 1-4 are connected to each other two by two as shown in fig. 3. That is, after one mining node declares its own identity, other mining nodes establish a TCP or UDP connection with it according to its IP address and node identifier, that is, open a connection channel above an IP layer, so as to perform subsequent message transmission between each other.
And step 204, the main node receives the transaction information sent by the transaction node in the block chain network.
Optionally, the master node 1, the master node 2, the master node 3, and the master node 4 may respectively receive transaction information sent by a transaction node in the blockchain network.
And step 205, the main node generates a block according to the transaction information, and sends the block to the other main nodes through the connection.
The main node 1, the main node 2, the main node 3 and the main node 4 contend for the accounting right of the current block in the block chain network, for example, the main node 1 contends for the accounting right, the main node 1 which contends for the accounting right can generate a block according to the received transaction information, and the block is sent to the main node 2, the main node 3 and the main node 4 through TCP connection or UDP connection respectively established between the main node 1 and the main node 2, the main node 3 and the main node 4. So that the master nodes 2, 3, 4 in the blockchain network can determine that the master node 1 has taken over the accounting right of the current block, so that the master nodes 2, 3, 4 take over the accounting right of the next block in the blockchain network.
In this embodiment, the IP address of the master node is specifically a public network IP address, and the master node may communicate with not only other master nodes but also other participating nodes other than the master node.
It should be noted that the block processing method described in this embodiment is applicable to the private chain network, because each node is not required to participate in accounting, only 3-5 mining nodes are reserved, and there are fewer mining nodes in the private chain network. In the public link network, the number of mining nodes is large, and the establishment and maintenance of the full-connection network of P2P are too complicated, so that the public link network is not recommended to use the method of the embodiment.
The method comprises the steps that identification information and an IP address of a main node are broadcasted to a block chain network through the main node, and the main node receives connection requests of other main nodes in the block chain network; establishing connection with the other main nodes according to the connection request; after a transaction information generation block sent by a transaction node is received, the block is sent to other main nodes, so that the other main nodes can contend for the accounting right of the next block, the transaction information in the block chain network can be directly sent to the main nodes without being broadcasted to the block chain network, and the network storm and network congestion are avoided.
Fig. 4 is a flowchart of a block processing method according to another embodiment of the invention. On the basis of the foregoing embodiments, the block processing method provided in this embodiment specifically includes the following steps:
The implementation manner and the specific process of step 401 are the same as those of step 201, and are not described herein again.

And step 403, the master node establishes connection with the other master nodes according to the connection request.
The step 403 is consistent with the step 203 in implementation and specific process, and is not described herein again.
The step 404 is consistent with the step 204 in implementation and specific process, and is not described here again.
And 405, the main node sends the transaction information to at least one secondary node so that the at least one secondary node performs mining calculation, wherein the mining calculation is used for robing the accounting right of the block in the block chain network.
In the blockchain network, if some nodes do not determine that the nodes are mine excavation nodes and want to undertake mine excavation work by sending broadcast messages to the blockchain network, the nodes can be used as secondary nodes, and as shown in fig. 3, the primary node 3 corresponds to a secondary node 3A, a secondary node 3B, a secondary node 3C and a secondary node 3D.
As shown in fig. 3, when the master node 3 receives the transaction information sent by the transaction node in the blockchain network, the master node 3 may send the transaction information to at least one of the secondary node 3A, the secondary node 3B, the secondary node 3C, and the secondary node 3D, so that at least one of the secondary node 3A, the secondary node 3B, the secondary node 3C, and the secondary node 3D performs calculation for preempting the current block accounting right to find an appropriate random number so as to make accounting successful.
And 406, the main node receives the accounting right robbing success message sent by the at least one secondary node.
When at least one of the auxiliary node 3A, the auxiliary node 3B, the auxiliary node 3C and the auxiliary node 3D robs the accounting right of the current block in the block chain network, the accounting right robbing success message is sent to the corresponding main node, namely the main node 3.
And step 407, the main node generates a block according to the transaction information, and sends the block to the other main nodes through the connection.
The master node 3 may generate a block according to the accounting right preemption success message and the received transaction information, and transmit the block to the master node 1, the master node 2, and the master node 4 through TCP connection or UDP connection between the master node 3 and the master nodes 1, 2, and 4, respectively.
According to the embodiment of the invention, at least one auxiliary node corresponding to the main node robs the accounting right of the current block in the block chain network, so that the success probability of the main node rob the accounting right is improved.
