建立区块链网络
当我们完成配置文件之后，便可以开始自己动手构建区块链网络了。
本章节中，我们选择编译 example 来启动区块链节点，该example当中
装载了 pow共识 和 asset模块.
当然，我们也可以自定义tripod来替换掉pow和asset 或者增加更多的 tripod。
首先我们利用该配置文件在本地启动第一个区块链节点:
INFO[0000] register Execution(Transfer) into Tripod(asset)
INFO[0000] register Execution(CreateAccount) into Tripod(asset)
INFO[0000] register Query(QueryBalance) into Tripod(asset)

注：上面输出的信息中， I am后面的一串地址为node1自己生成的p2p地址， 节点2 和 节点3 需要连接这个地址来构建区块链网络。
然后我们在另一个路径下写好配置文件部署第二个节点并启动:

上图输出中 fetch history blocks from (1) to (3) 表示节点2启动时从节点1处获取到从高度1到3的历史区块
最后我们在第三个路径下写好配置文件部署第二个节点并启动:
