Requirements

To run the 0G Validator from source,you need to meet the following conditions:

• - Memory: 8 GB RAM
• - CPU: 4 cores
• - Disk: 500 GB NVME SSD
• - Bandwidth: 100mbps Gbps for Download / Upload - Linux amd64 arm64 (The guide was tested on Ubuntu 20.04 LTS)

Guide to running 0G Validator from source

1. Install required packages

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

2. Install 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" >> ~/.bash_profile && \
source ~/.bash_profile && \
go version

3.Build evmosd binary

wget https://rpc-zero-gravity-testnet.trusted-point.com/evmosd
chmod +x ./evmosd
mv ./evmosd /usr/local/bin/
evmosd version

4. Set up variables

Customize if you need

echo 'export MONIKER="Name_you_choice"' >> ~/.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

note: MONIKER="Name_you_choice"' is a name you choice

5. Initialize the node

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

6. Download genesis.json

wget https://rpc-zero-gravity-testnet.trusted-point.com/genesis.json -O $HOME/.evmosd/config/genesis.json

7. Add seeds and peers to the 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. Change ports (Optional)

EXTERNAL_IP=$(wget -qO- eth0.me) \
PROXY_APP_PORT=26658 \
P2P_PORT=26656 \
PPROF_PORT=6060 \
API_PORT=1317 \
GRPC_PORT=9090 \
GRPC_WEB_PORT=9091

sed -i \
    -e "s/\(proxy_app = \"tcp:\/\/\)\([^:]*\):\([0-9]*\).*/\1\2:$PROXY_APP_PORT\"/" \
    -e "s/\(laddr = \"tcp:\/\/\)\([^:]*\):\([0-9]*\).*/\1\2:$RPC_PORT\"/" \
    -e "s/\(pprof_laddr = \"\)\([^:]*\):\([0-9]*\).*/\1localhost:$PPROF_PORT\"/" \
    -e "/\[p2p\]/,/^\[/{s/\(laddr = \"tcp:\/\/\)\([^:]*\):\([0-9]*\).*/\1\2:$P2P_PORT\"/}" \
    -e "/\[p2p\]/,/^\[/{s/\(external_address = \"\)\([^:]*\):\([0-9]*\).*/\1${EXTERNAL_IP}:$P2P_PORT\"/; t; s/\(external_address = \"\).*/\1${EXTERNAL_IP}:$P2P_PORT\"/}" \
    $HOME/.evmosd/config/config.toml

sed -i \
    -e "/\[api\]/,/^\[/{s/\(address = \"tcp:\/\/\)\([^:]*\):\([0-9]*\)\(\".*\)/\1\2:$API_PORT\4/}" \
    -e "/\[grpc\]/,/^\[/{s/\(address = \"\)\([^:]*\):\([0-9]*\)\(\".*\)/\1\2:$GRPC_PORT\4/}" \
    -e "/\[grpc-web\]/,/^\[/{s/\(address = \"\)\([^:]*\):\([0-9]*\)\(\".*\)/\1\2:$GRPC_WEB_PORT\4/}" $HOME/.evmosd/config/app.toml

9. Configure prunning to save storage (Optional)

sed -i.bak -e "s/^pruning *=.*/pruning = \"custom\"/" $HOME/.evmosd/config/app.toml
sed -i.bak -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"100\"/" $HOME/.evmosd/config/app.toml
sed -i.bak -e "s/^pruning-interval *=.*/pruning-interval = \"10\"/" $HOME/.evmosd/config/app.toml

10. Set min gas price

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

11. Enable indexer (Optional)

sed -i "s/^indexer *=.*/indexer = \"kv\"/" $HOME/.evmosd/config/config.toml

12. Create a service file

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

13. Start the node

sudo systemctl daemon-reload && 

sudo systemctl enable ogd && 

sudo systemctl restart ogd && 

sudo journalctl -u ogd -f -o cat

Ctrl C => Exit the logs viewing process and do the next steps

14. Download snapshot 

wget https://rpc-zero-gravity-testnet.trusted-point.com/latest_snapshot.tar.lz4

stop the node

sudo systemctl stop ogd

Backup priv_validator_state.json

cp $HOME/.evmosd/data/priv_validator_state.json $HOME/.evmosd/priv_validator_state.json.backup

Reset DB

evmosd tendermint unsafe-reset-all --home $HOME/.evmosd --keep-addr-book

Extract files fromt the arvhive

lz4 -d -c ./latest_snapshot.tar.lz4 | tar -xf - -C $HOME/.evmosd

Move priv_validator_state.json back

mv $HOME/.evmosd/priv_validator_state.json.backup $HOME/.evmosd/data/priv_validator_state.json

Restart the node

sudo systemctl restart ogd && sudo journalctl -u ogd -f -o cat

then Ctrl C => next steps

15. Create a wallet for your validator

evmosd keys add $WALLET_NAME

!Note: save seed pharse. If you don't save the seed pharse you can't get it back

if you want to recover wallet use command:

evmosd keys add $WALLET_NAME --recover

16.Extract the HEX address to request some tokens from the faucet

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

example: 0x93849.... This command will appear an address to use for faucet tokens

can extract the private keys in address above, use command: 

evmosd keys unsafe-export-eth-key $WALLET_NAME

you can add account with private keys in metamask, account use faucet token if you want

!note: save private keys add to metamask to faucet token
17.faucet token

https://faucet.0g.ai/

Note: The faucet gives you 100000000000000000aevmos. To make the validator join the active set you need at least 1000000000000000000aevmos (10 times more)

18.Check wallet balances

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

if your node synced, pls check here

evmosd status | jq .SyncInfo.catching_up

if "catching_up"=False you can create validator

19. Create a validator

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 \
--website="https://twitter...." \
--details="Stevendo handsome very" \
--gas=500000 --gas-prices=99999aevmos \
-y

please change variable your replace 

--website="your config"

--details="your config"

You can check your Validator status here. Please allow some time for your validator to be added to the 0G Validator list: Here

backup validator keys

cp $HOME/.evmosd/data/priv_validator_state.json $HOME/.evmosd/priv_validator_state.json.backup

check after create validator

evmosd q staking validator $(evmosd keys show $WALLET_NAME --bech val -a)

Command useful

delegate your node

evmosd tx staking delegate $(evmosd keys show $WALLET_NAME --bech val -a)  80999950000500000aevmos --from $WALLET_NAME --gas=500000 --gas-prices=99999aevmos -y

edit 80999950000500000aevmos in your balance 

remove node

sudo systemctl stop ogd
sudo systemctl disable ogd
sudo rm /etc/systemd/system/ogd.service
rm -rf $HOME/.evmosd $HOME/0g-evmos
