### 智能合约开发（2）基本操作 ###

创建用户  
geth account new

我们多创建几个账号，如下：  
![在这里插入图片描述][20200131182830591.png]  
我们打开一个账户文件看看里边的内容：  
![在这里插入图片描述][20200131183002126.png]  
包括内容如下：  
address 公钥地址  
crypto 密码 aes-128 密码  
私钥密码并没有，私钥为之前输入过口令衍生  
cipherparams 密文格式等  
其他内容这里不详细描述

#### 编写初始块文件 ####

编写初始块与区块链配置文件，然后生成区块

{ 
    	"nonce":"0x0000000000000042",
    	"difficulty":"0x1",
    	"alloc":{ 
    		"cd3e93c51b9f748ebca8e62790fc2704bdbe3f5d":{ 
    		"balance":"20000009800000000000000000000"
    		},
    		"980950f6e27a3d06e19be62be06bfe88e88cc0a7":{ 
                    "balance":"20000009800000000000000000000"
                    },
    		"929a86cf912859737f1d507beb08873139c0c10e":{
