前言

最近看到区块链行业有一个新的公链挺有意思的，官方目前貌似还没有开始宣传，只给提供了一个点对点的加密聊天工具，试了下聊天工具，没有目前还没有微信那么全，但是基本能用了，但其主打是隐私，这块因为客户端还没有开源，不好评价~但是看官网，后面自己搭建聊天服务器，但是服务器的代码和聊天的代码目前还没有开源，不知道啥时候能开源，但是公链的代码已经开源了，我尝试的搭建了一下测试服务器，貌似可以成功！关注其下一步发展

准备工作

我从他们的官网https://www.netcloth.org找到了github的相关地址，也就是在https://github.com/NetCloth/netcloth-chain这里。然后找到了他们的环境搭建文档,https://docs.netcloth.org，本文主要参照该文档。

搭建相关环境

GIT的安装

sudo apt-get update
sudo apt-get install git

GO环境的安装

检查当前go环境

查看golang版本
go version

在ubuntu上执行结果如下:
[20:09:04] root:~ # go version
go version go1.12.2 linux/amd64

在mac os上执行结果如下:
➜  ~ go version
go version go1.13 darwin/amd64

如果版本号低于1.12.2请彻底卸载golang，并将GO相关的path从PATH环境变量中删除

安装go环境

# macOS系统执行如下命令
wget https://dl.google.com/go/go1.12.2.darwin-amd64.tar.gz
tar -xvf go1.12.2.darwin-amd64.tar.gz
mv go /usr/local

# ubuntu系统执行如下命令
wget https://dl.google.com/go/go1.12.2.linux-amd64.tar.gz
tar -xvf go1.12.2.linux-amd64.tar.gz
sudo mv go /usr/local

设置环境变量

# 修改~/.bashrc，添加如下：
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH
export GO111MODULE=on

使环境变量生效

source ~/.bashrc

源码编译nch节点程序

# 获取nch 源码
git clone https://github.com/NetCloth/netcloth-chain.git
cd netcloth-chain && git checkout v1.0.2

# 设置goproxy(make install过程会下载依赖的go模块,设置适合自己的代理,大陆用户可以设置以下代理来加快下载速度)
export GOPROXY=https://mirrors.aliyun.com/goproxy/

# 安装statik
sudo apt-get update
sudo apt-get install golang-statik

# 编译安装
make install

# 编译完成后，检查版本号
nchd version
nchcli version

配置节点

nchd init local-nch-1 --chain-id nch-alphanet

# 拷贝主节点genesis文件,此处从github下载
wget https://raw.githubusercontent.com/NetCloth/docs/master/alphanet/genesis.json -O  ~/.nchd/config/genesis.json
如果wget很慢或失败请尝试手动下载文件,地址:https://github.com/NetCloth/docs/blob/master/alphanet/genesis.json

修改配置文件：~/.nchd/config/config.toml， 添加主节点seed， 如下：
# Comma separated list of seed nodes to connect to
seeds = "[email protected]:26656"

# Comma separated list of nodes to keep persistent connections to
persistent_peers = "[email protected]:26656"

启动节点同步区块

# 执行下面的命令后，控制台会打印日志，同步区块
nchd start --log_level "*:debug" --trace

查看节点同步状态

# 打开一个新的终端
curl http://127.0.0.1:26657/status

# 输出如下：
{
  "jsonrpc": "2.0",
  "id": "",
  "result": {
    "node_info": {
      "protocol_version": {
        "p2p": "7",

      "other": {
        "tx_index": "on",
        "rpc_address": "tcp://127.0.0.1:26657"
      }
    },
    "sync_info": {  //当前节点信息
      "latest_block_hash": "A4E5D60DE7CFB6598846A4131302C8FD28F2697DF2291B33B0892A9EACB562D8", // 最新的区块 hash

      "latest_block_height": "1489",     // 当前节点同步到的最新区块高度                                                      //最新区块高度
      "latest_block_time": "2019-09-10T05:33:13.428333584Z",                                  //最新区块时间 
      "catching_up": false
    },
    "validator_info": { // 验证人信息
      "address": "92E0F0A50779E67A2AC25AAF6BCD1E5CF0841DFE",
      "pub_key": {
        "type": "tendermint/PubKeyEd25519",
        "value": "cGvHGxHXzOk/L5yVtxeyS9U1mGBNFszvAdYlQoQVGCw="
      },
      "voting_power": "0"
    }
  }

当节点同步到的区块高度和区块浏览器上一致时，表示节点已经同步完成，此时一个全节点就部署完成了。
至于在哪里查看呢:explorer.netcloth.org

成为验证人

创建账号

# usage: nchcli keys add 

# 示例：
nchcli keys add dan
# 按照提示输入加密账号用的密码(后续执行各种交易都需要用该密码)，将命令返回的信息谨慎保存

可以得到类似

- name: dan
  type: local
  address: nch1p3fuppcxud5rjsaywuyuguh6achmj5p0r6z6ve  // 地址
  pubkey: nchpub1addwnpepqg8mfc6t9eaw9lal0c4tzma5vgmqzkgszwcgljcz3sy8rd2rukgxz9dtmph  // 公钥
  mnemonic: "" 
  threshold: 0
  pubkeys: []

**Important** write this mnemonic phrase in a safe place.
It is the only way to recover your account if you ever forget your password.
# 下面的即助记词
connect plug cigar purchase inflict enroll ten limb quantum never supply grid home case process claw truly grape federal liberty tree remove side quantum

的输出，其中nch1p3fuppcxud5rjsaywuyuguh6achmj5p0r6z6ve就是我们的地址了
然后去测试网申请币

https://docs.netcloth.org/nch/get_token?

把尖括号和里面的address替换成我们生成的钱包地址即可，这样就可以领到币了，然后可以用这些币去抵押做验证人

设置nchcli环境变量

nchcli config chain-id nch-alphanet 
nchcli config output json 
nchcli config indent true 
nchcli config trust-node true

创建验证人

# usage: nchcli tx staking create-validator --from= --amount=1000000unch --moniker=  --commission-rate=0.1 --identity=

# 示例：
nchcli tx staking create-validator \
  --amount=10000unch \
  --pubkey=$(nchd tendermint show-validator -o text) \
  --moniker="dan" \
  --commission-rate="0.10" \
  --commission-max-rate="0.20" \
  --commission-max-change-rate="0.01" \
  --min-self-delegation="100" \
  --from=$(nchcli keys show dan -a)
  
# 重点关注命令中最后一行--from=$(nchcli keys show dan -a)，dan对应的账号作为抵押者将成为要创建的验证人

查询验证人列表

nchcli query staking validators

可以发现多了一个moniker为dan的验证人

    "min_self_delegation": "1",
    "self_delegation": "1000000.000000000000000000"
  }
]

此时其状态为0，0表示还没有绑定，因为没有抵押足够的unch;

1000000unch为1个voting power，voting power的最小单位为1，只有它>=1时候才能够变成绑定状态2，才能成为活跃验证者出块，因此至少还需要抵押990000unch

给自己抵押500000unch

nchcli tx staking delegate nchvaloper18q4pv9qvmqx7dcd2jq3dl3d0755urk8300709e 500000unch --from $(nchcli keys show dan -a)

再次确认验证人状态为活跃验证人

nchcli query staking validators

# 可以看到dan对应的status变成2，此时节点成为活跃验证人，可通过区块浏览器查看出块情况

然后查看
explorer.netcloth.org
我们就已经成为验证人，可以正常出块了！！！
