2.查看当前账户信息

>eth.accounts>["0xa0aee14352a0f3f5dcde30a45be6b06003c88073", "0xfd6f9c291fb6137f7809d13f6717baf691dc6bf1"]

3.创建新的账户

//引号内是账户密码>personal.newAccount('1')>INFO [08-16|08:58:27] New wallet appeared                      url=keystore:///Users/xue/Library/E… status=Locked"0x9b23d981e7d7655c9483202c2404e8d8e638e19c"

4.查看当前链上区块数

>eth.blockNumber117

5.查询当前账户余额

//账户1> eth.getBalance(eth.accounts[0])579531250000000000000

//账户2> eth.getBalance(eth.accounts[1])10000000000000000000
