融资3500万美金的AI项目，0G Labs验证者节点图文教程

1.安装需要的包

sudo apt update && \
sudo apt install curl git jq build-essential gcc unzip wget lz4 -y

2.安装Go

cd $HOME && \
ver="1.21.3" && \
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz" && \
sudo rm -rf /usr/local/go && \
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz" && \
rm "go$ver.linux-amd64.tar.gz" && \
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile && \
source $HOME/.bash_profile && \
go version

3. 构建evmosd二进制文件

git clone https://github.com/0glabs/0g-evmos.git
cd 0g-evmos
git checkout v1.0.0-testnet
make install
evmosd version

4. 设置变量

echo 'export MONIKER="My_Node"' >> ~/.bash_profile
echo 'export CHAIN_ID="zgtendermint_9000-1"' >> ~/.bash_profile
echo 'export WALLET_NAME="wallet"' >> ~/.bash_profile
echo 'export RPC_PORT="26657"' >> ~/.bash_profile
source $HOME/.bash_profile

5. 初始化节点

cd $HOME
evmosd init $MONIKER --chain-id $CHAIN_ID
evmosd config chain-id $CHAIN_ID
evmosd config node tcp://localhost:$RPC_PORT
evmosd config keyring-backend os # You can set it to "test" so you will not be asked for a password

6.下载genesis.json

wget https://github.com/0glabs/0g-evmos/releases/download/v1.0.0-testnet/genesis.json -O $HOME/.evmosd/config/genesis.json

7. 将种子和对等点添加到 config.toml

PEERS="1248487ea585730cdf5d3c32e0c2a43ad0cda973@peer-zero-gravity-testnet.trusted-point.com:26326" && \
SEEDS="8c01665f88896bca44e8902a30e4278bed08033f@54.241.167.190:26656,b288e8b37f4b0dbd9a03e8ce926cd9c801aacf27@54.176.175.48:26656,8e20e8e88d504e67c7a3a58c2ea31d965aa2a890@54.193.250.204:26656,e50ac888b35175bfd4f999697bdeb5b7b52bfc06@54.215.187.94:26656" && \
sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.evmosd/config/config.toml

8. 设置最低 Gas 价格

sed -i "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.00252aevmos\"/" $HOME/.evmosd/config/app.toml

9.创建服务文件

sudo tee /etc/systemd/system/ogd.service > /dev/null <<EOF
[Unit]
Description=OG Node
After=network.target

[Service]
User=$USER
Type=simple
ExecStart=$(which evmosd) start --home $HOME/.evmosd
Restart=on-failure
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

10.启动节点

sudo systemctl daemon-reload && \
sudo systemctl enable ogd && \
sudo systemctl restart ogd && \
sudo journalctl -u ogd -f -o cat

出现此界面，代表成功启动节点

CTRL+C 退出即可

11. 为您的验证器创建一个钱包

evmosd keys add $WALLET_NAME

12. 提取十六进制地址以向水龙头请求一些代币

输入下面命令

echo "0x$(evmosd debug addr $(evmosd keys show $WALLET_NAME -a) | grep hex | awk '{print $3}')"

13. 领取测试币，每次只能0.1

用上面复制的16进制地址领取测试币

https://faucet.0g.ai/

14.查看钱包余额（需要区块同步完成才可以查看）

evmosd q bank balances $(evmosd keys show $WALLET_NAME -a) 

15. 创建验证器，需要等待区块同步完成

检查同步状态，同步区块之后可以创建验证者

evmosd status | jq .SyncInfo

evmosd tx staking create-validator \
  --amount=10000000000000000aevmos \
  --pubkey=$(evmosd tendermint show-validator) \
  --moniker=$MONIKER \
  --chain-id=$CHAIN_ID \
  --commission-rate=0.05 \
  --commission-max-rate=0.10 \
  --commission-max-change-rate=0.01 \
  --min-self-delegation=1 \
  --from=$WALLET_NAME \
  --identity="" \
  --website="" \
  --details="0G to the moon!" \
  --gas=500000 --gas-prices=99999aevmos \
  -y
