The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

FIG. 1 is a flowchart of a node communication method according to an embodiment of the present invention. As shown in FIG. 1, in this embodiment, the present invention provides a node communication method suitable for blockchain nodes. The above method includes:

S12: Save the IP addresses of each network card of the current node into the first address set; wherein, the IP addresses of the network cards include a public network IP address and a local area network IP address;

S14: Broadcast the first address set to several blockchain nodes for each blockchain node:

Specifically, to broadcast the first address set to several blockchain nodes includes "broadcasting the first address set to seed nodes for broadcasting the first address set to other blockchain nodes", the current node does not have a local area network IP address Take the LAN IP address as null as an example, assuming that there are blockchain nodes N1 to N25 in the blockchain network, where N1 and N2 are nodes in the A LAN, and N3 to N25 do not have LAN IP addresses;

Take N1 as an example:

N1 performs step S12, and saves the public network IP address (pubIP_N1:port) and local area network IP address (localIP_N1:port) of N1 in the address set [pubIP_N1:port,localIP_N1:port];

N1 broadcasts [pubIP_N1:port,localIP_N1:port] to the seed node seed1;

seed1 broadcasts [pubIP_N1:port,localIP_N1:port] to N2~N25;

According to [pubIP_N1:port,localIP_N1:port], N2~N25 judge whether they are in the same LAN as N1:

N2 and N1 are in the same local area network, and N2 establishes a connection with N1 according to localIP_N1:port;

N3-N25 and N1 are not in the same local area network, and N3-N5 establishes a connection with N1 according to pubIP_N1:port.

The principles of N2 and N1 are similar, and will not be repeated here.

Take N3 as an example:

N3 performs step S12, and saves the public network IP address (pubIP_N3:port) and local area network IP address (null) of N3 in the address set [pubIP_N3:port,null];

N3 broadcasts [pubIP_N3:port,null] to the seed node seed1;

seed1 broadcasts [pubIP_N3:port,null] to N1, N2, N4~N25;

N1, N2, N4~N25 judge whether they are in the same LAN as N3 according to [pubIP_N3:port,null]:

Since the LAN IP address of N3 is null, N1, N2, N4-N25 and N3 are not in the same LAN. N1, N2, N4-N25 establish connections with N3 according to pubIP_N3:port.

The principles of N4 to N25 are similar to those of N3, and are not repeated here.

For example, the first number of blockchain nodes should be the blockchain nodes with the closest physical distance to the current node. A number of blockchain nodes should be the blockchain nodes with the closest logical distance to the current node.

In more embodiments, when the current node does not have a local area network IP address, the local area network IP address in the address set can also be configured according to actual requirements, for example, the configuration is empty, or other identifiers used to indicate that the current node does not have a local area network IP address , can achieve the same technical effect.

Those skilled in the art should understand that the format of the IP address of the public network and the local area network can be configured according to actual requirements, for example, it can also be configured as: pubIP_N1:port:PID, localIP_N1:port:PID, or, pubIP_N1:port:PID: pubkey_N1, localIP_N1:port:PID:pubkey_N1, can achieve the same technical effect.
