以太坊生成创世区块配置文件导向工具

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!

Which consensus engine to use? (default = clique)

 1. Ethash - proof-of-work

 2. Clique - proof-of-authority

> 2

// 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

Which accounts are allowed to seal? (mandatory at least one)

INFO [03-23|17:13:51] Configured new genesis block

What would you like to do? (default = stats)

 1. Show network stats

 2. Manage existing genesis

 3. Track new remote server

 4. Deploy network components

> 2

 1. Modify existing fork rules

 2. Export genesis configuration

 3. Remove genesis configuration

> 2

Which file to save the genesis into? (default = gethtest.json)

> genesis.json

INFO [03-23|17:15:57] Exported existing genesis block

生成genesis.json文件内容太长，就不展示了，大家自己生成吧。
