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 = "1d71d8f60a20a5a0f379226b092aa56b64348347@18.191.12.61:26656"# Comma separated list of nodes to keep persistent connections to persistent_peers = "1d71d8f60a20a5a0f379226b092aa56b64348347@18.191.12.61:26656"

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", "block": "10", "app": "0" }, "id": "204d94d5a6dbf73a89101a0d084c2fb56462963a", //节点id "listen_addr": "tcp://0.0.0.0:26656", // 节点p2p连接监听地址 "network": "nch-alphanet", //chain-id "version": "0.32.2", "channels": "4020212223303800", "moniker": "local-nch-1", // 节点名称 "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_app_hash": "32F0B29280EDF3BEAE98424D9AA256EDBEFC973D1C33431A8D74FCA3BC3B6582", "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[ { "operator_address": "nchvaloper18q4pv9qvmqx7dcd2jq3dl3d0755urk8300709e", "consensus_pubkey": "nchvalconspub1zcjduepqua3tt6kl7v7sd558m24fj3s039fhmsxcv9fc49rqn0uwcuelvrmsdp3hwt", "jailed": false, "status": 0, "tokens": "10000", "delegator_shares": "10000.000000000000000000", "description": { "moniker": "dan", "identity": "", "website": "", "details": "" }, "unbonding_height": "0", "unbonding_time": "1970-01-01T00:00:00Z", "commission": { "commission_rates": { "rate": "0.100000000000000000", "max_rate": "0.200000000000000000", "max_change_rate": "0.010000000000000000" }, "update_time": "2019-10-30T11:21:01.013731989Z" }, "min_self_delegation": "100", "self_delegation": "10000.000000000000000000" }, { "operator_address": "nchvaloper133vmttt6n49jac5zn3z0klcpe7m8qluglfu58z", "consensus_pubkey": "nchvalconspub1zcjduepq3zr5cyenfyz8qprts7344nl8gclm3st669hyrhgy9gae7l8ajuus5uttte", "jailed": false, "status": 2, "tokens": "1000000", "delegator_shares": "1000000.000000000000000000", "description": { "moniker": "local-nch", "identity": "", "website": "", "details": "" }, "unbonding_height": "0", "unbonding_time": "1970-01-01T00:00:00Z", "commission": { "commission_rates": { "rate": "0.100000000000000000", "max_rate": "0.200000000000000000", "max_change_rate": "0.100000000000000000" }, "update_time": "2019-10-30T08:10:34.407927185Z" }, "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[ { "operator_address": "nchvaloper18q4pv9qvmqx7dcd2jq3dl3d0755urk8300709e", "consensus_pubkey": "nchvalconspub1zcjduepqua3tt6kl7v7sd558m24fj3s039fhmsxcv9fc49rqn0uwcuelvrmsdp3hwt", "jailed": false, "status": 2, "tokens": "1000000", "delegator_shares": "1000000.000000000000000000", "description": { "moniker": "dan", "identity": "", "website": "", "details": "" }, "unbonding_height": "0", "unbonding_time": "1970-01-01T00:00:00Z", "commission": { "commission_rates": { "rate": "0.100000000000000000", "max_rate": "0.200000000000000000", "max_change_rate": "0.010000000000000000" }, "update_time": "2019-10-30T11:21:01.013731989Z" }, "min_self_delegation": "100", "self_delegation": "510000.000000000000000000" }, { "operator_address": "nchvaloper133vmttt6n49jac5zn3z0klcpe7m8qluglfu58z", "consensus_pubkey": "nchvalconspub1zcjduepq3zr5cyenfyz8qprts7344nl8gclm3st669hyrhgy9gae7l8ajuus5uttte", "jailed": false, "status": 2, "tokens": "1000000", "delegator_shares": "1000000.000000000000000000", "description": { "moniker": "local-nch", "identity": "", "website": "", "details": "" }, "unbonding_height": "0", "unbonding_time": "1970-01-01T00:00:00Z", "commission": { "commission_rates": { "rate": "0.100000000000000000", "max_rate": "0.200000000000000000", "max_change_rate": "0.100000000000000000" }, "update_time": "2019-10-30T08:10:34.407927185Z" }, "min_self_delegation": "1", "self_delegation": "1000000.000000000000000000" } ]# 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！！！
