搭建自己的以太坊网络发布erc20代币

1.搭建自己的以太坊网络

目前以太坊官方提供了两种网络：线上生产网络、测试网络。

以太坊生产网络就是真正有价值的的以太币运行的网络。我们使用的以太币进行转账、支付都是在生产网络上进行，每一个操作都需要消耗实实在在的ETH。智能合约也是部署在生产网络上，智能合约代码的执行调用都清晰可查，并且可供所有开发者调用。

以太坊的测试网络也是官方提供专供用户来开发、调试和测试的。但是测试网络的节点也是全球化的，现在测试网络的区块数量也很大，执行速度较慢，不便于开发、调试。

开始

下面我们使用Geth安装自己的以太坊私有网络 PrivateNetwork。

下载对应 go-ethereum 使用go语言开发

Geth安装可以直接到官网下载对应的版本，进行安装：https://ethereum.github.io/go-ethereum/downloads/

版本1.8.1

配置创世币

配置创世块来创建私有链。同一个网络中，创世块必须是一样的，否则无法联通。创建eth目录，在该目录下新建创世块文件 gen.json

{

"config":{

 "chainId":9999,

 "homesteadBlock":0,

 "eip155Black":0,

 "eip158Black":0

},

"nonce":"0x0000000000000042",

"mixhash":"0x0000000000000000000000000000000000000000000000000000000000000000",

"difficulty": "0x4000",

"alloc": {},

"coinbase":"0x0000000000000000000000000000000000000000",

"timestamp": "0x00",

"parentHash":"0x0000000000000000000000000000000000000000000000000000000000000000",

"extraData": "",

"gasLimit":"0xffffffff"

}

字段名	类型
mixhash	与nonce配合用于挖矿，由上一个区块的一部分生成的hash。注意他和nonce的设置需要满足以太坊的Yellow paper, 4.3.4. Block Header Validity, (44)章节所描述的条件。.
nonce	nonce就是一个64位随机数，用于挖矿，注意他和mixhash的设置需要满足以太坊的Yellow paper, 4.3.4. Block Header Validity, (44)章节所描述的条件。
difficulty	设置当前区块的难度，如果难度过大，cpu挖矿就很难，这里设置较小难度
alloc	用来预置账号以及账号的以太币数量，因为私有链挖矿比较容易，所以我们不需要预置有币的账号，需要的时候自己创建即可以。
coinbase	矿工的账号，随便填
timestamp	设置创世块的时间戳
parentHash	上一个区块的hash值，因为是创世块，所以这个值是0
extraData	附加信息，随便填，可以填你的个性信息
gasLimit	该值设置对GAS的消耗总量限制，用来限制区块能包含的交易信息总和，因为我们是私有链，所以填最大。

init 执行然后执行命令初始化节点

geth --datadir "./" init gen.json

可以看到将节点数据写入了对应的文件夹中，此时当前目录下面会新增出两个文件夹geth和keystore

geth中用以保存区块链的相关数据

keystore中保存的是用户数据

创建私有联

输入命令：

geth --datadir "./" --nodiscover console

当看到Welcome to the Geth JavaScript console!的提示，说明已经启动成功

在私有链上创建账户

输入命令：personal.newAccount("123456")

"123456"表示此账号的密码.

0x71e71645f6f999a5b723f862fd2d8a590ca961c3

输入命令eth.accounts可以查看新账户

这样，通过这两个命令可以创建出多个用户出来

若输入命令：personal.newAccount()

则系统会提示你输入账号密码，并确认，最后会显示一个新生成的账号

挖矿

输入命令：miner.start() 或者miner.start(1)

后者表示只使用一个线程工作，这样系统不会太卡

查看主账户中以太币的数量

输入命令： eth.getBalance(eth.accounts[0]) 结果不为0，说明挖矿成功
