確保本地以安裝好go-ethernum環境
genesis配置檔案

初始化兩個節點
初始化Node1
build/bin/geth --datadir ../ethereumdata/data/00 init ./genesis.json
初始化Node2
build/bin/geth --datadir ../ethereumdata/data/01 init ./genesis.json
啟動節點Node1
build/bin/geth --datadir ../ethereumdata/data/00 --networkid 314590 --ipcdisable --port 61910 --rpcport 8200 console
查詢當前節點資訊
新視窗開啟節點Node2
build/bin/geth --datadir ../ethereumdata/data/01 --networkid 314590 --ipcdisable --port 61911 --rpcport 8101 --bootnodes "enode://5a55ee4e0daaac7431cb7446a2c9fc554130768dfb1a14e726871c0e29d29ab84[email protected][::]:61910" console
修改ip地址 127.0.0.1
啟動成功
當啟動Node1時，peers為0
啟動Node2並將Node1新增到bootnodes中去
Node1執行 admin.peers()
Node2執行admin.peers
再加一個節點Node3
build/bin/geth --datadir ../ethereumdata/data/02 init ./genesis.json啟動Node3
build/bin/geth --datadir ../ethereumdata/data/02 --networkid 314590 --ipcdisable --port 61912 --rpcport 8102 --bootnodes "enode://5a55ee4e0daaac7431cb7446a2c9fc554130768dfb1a14e726871c0e29d29ab84[email protected]127.0.0.1:61910" console再查詢Node1的 admin.peers
Node2 admin.peers

原因是當前環境沒有賬戶，需要建立一個賬戶
解決：personal.newAccount("xxx"), 這裡建立一個新賬戶， 注意有的同學會疑問以前都有賬戶啊，怎麼現在沒啦，可能你啟動geth的路徑有問題
Node1 建立賬號
personal.newAccount("111111")Node2 建立賬號
personal.newAccount("123")開始轉賬交易

當前賬戶餘額不足
轉賬操作只有在啟動挖礦後才能生效，切記！！！！
轉賬15個
歡迎大家一起加入討論！！！
