Build a blockchain network
When we have completed the configuration file, we can start building the blockchain network by ourselves.
In this chapter, we choose to compile example to start the blockchain node, in this example
Loaded with pow consensus and asset module.
Of course, we can also customize tripod to replace pow and asset or add more tripod.
First we use the configuration file to start the first blockchain node locally:

Note: In the information output above, the string of addresses after I am is the p2p address generated by node1 itself, and node 2 and node 3 need to connect to this address to build a blockchain network.
Then we write the configuration file in another path to deploy the second node and start it:

In the output of the above figure, fetch history blocks from (1) to (3) means that when node 2 starts, the history blocks from height 1 to 3 are obtained from node 1
Finally, we write the configuration file in the third path to deploy the second node and start it:
