最近，一直在研究以太坊，今天发现了一个很有意思的工具，分享给大家。
puppeth 是创建新以太坊网络的向导工具。我们可以用这个工具来生成创世区块配置文件。
话不多说，直接看执行生成过程 ：
➜ geth_net puppeth
+------------------------------------------------------------------------------------+
| Welcome to puppeth, your Ethereum private network manager |
| |
| This tool lets you create a new Ethereum network down to |
| the genesis block, bootnodes, miners and ethstats servers |
| without the hassle that it would normally entail. |
| |
| Puppeth uses SSH to dial in to remote servers, and builds |
| its network components out of Docker containers using the |
| docker-compose toolset. |
+-------------------------------------------------------------------------------------+
Please specify a network name to administer (no spaces or hyphens, please)
> gethtest
Sweet, you can set this via --network=gethtest next time!

// 设置出块时间，以秒为单位
How many seconds should blocks take? (default = 15)
> 5
// 设置有签名权限的用户

INFO [03-23|17:13:51] Configured new genesis block
What would you like to do? (default = stats)
1. Show network stats

生成genesis.json文件内容太长，就不展示了，大家自己生成吧。
