Node request becomes from memory node, and the solicited message includes the identification information of the destination node.
As shown in figure 3,31 indicate the primary storage node in block chain network, 32 indicate the target section in block chain network
Point, the request of destination node 32 become from memory node, and destination node 32 has the public network IP address of oneself.33 indicate another target
Node, the request of destination node 33 become from memory node, and destination node 33 does not have public network IP address, destination node 33 to pass through network
Address conversion (Network Address Translation, NAT) is communicated with block chain network, and 34 indicate NAT, and 35 indicate to be somebody's turn to do
Query node in block chain network.In the present embodiment, by being that the query node 35 provides inquiry service from memory node.This
Place only schematically illustrates, and does not limit the specific network architecture of block chain network.In addition, query node 35 can be under NAT
Node, may not be the node under NAT.
When block chain network is added for the first time in destination node 32 or destination node 33, need from the destination node 32 or
The adjacent node of destination node 33 obtains wound generation block, and optionally, the node in block chain network stores invasive generation block.For
Ensure that the destination node 32 or destination node 33 get true wound generation block, the destination node 32 or destination node 33 can
To send wound generation block inquiry request to multiple adjacent nodes, for example, destination node 32 or destination node 33 to adjacent node B and
Adjacent node C sends wound generation block inquiry request respectively, and adjacent node B and adjacent node C receive wound generation block inquiry and ask
After asking, the wound generation block being respectively locally stored is sent to destination node 32 or destination node 33, destination node 32 or target section
Whether point 33 compares adjacent node B consistent with the wound generation block that adjacent node C is fed back, if adjacent node B and adjacent node C are anti-
The wound generation block of feedback is consistent, then the wound generation block is stored in local by destination node 32 or destination node 33；If adjacent node B
Inconsistent with the wound generation block of adjacent node C feedbacks, then destination node 32 or destination node 33 can also continue to adjacent node D
Wound generation block inquiry request is sent with adjacent node E, and receives the wound generation block that adjacent node D and adjacent node E are fed back respectively,
If the wound generation fed back more than the adjacent node of preset ratio in adjacent node B, adjacent node C, adjacent node D and adjacent node E
