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

Install Go

cd $HOME && \
ver="1.22.0" && \
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz" && \
sudo rm -rf /usr/local/go && \
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz" && \

echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile && \
source $HOME/.bash_profile && \
go version

Install initia binary

git clone https://github.com/initia-labs/initia.git
cd initia
git checkout v0.2.15
make install
initiad version

Set up variables

# Customize if you need
echo 'export MONIKER="My_Node"' >> ~/.bash_profile
echo 'export CHAIN_ID="initiation-1"' >> ~/.bash_profile
echo 'export WALLET_NAME="wallet"' >> ~/.bash_profile
echo 'export RPC_PORT="26657"' >> ~/.bash_profile
source $HOME/.bash_profile

Initialize the node

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

Download genesis.json

wget https://initia.s3.ap-southeast-1.amazonaws.com/initiation-1/genesis.json -O $HOME/.initia/config/genesis.json

Add seeds and peers to the config.toml

PEERS="[email protected]:30656,[email protected]:26656,[email protected]:53456,[email protected]:26313,[email protected]:25756,[email protected]:26656,[email protected]:26656,[email protected]:53456,[email protected]:26656,[email protected]:26656,[email protected]:19656,[email protected]:26656,[email protected]:53456,[email protected]:26656,[email protected]:53456,[email protected]:26656,[email protected]:36656,[email protected]:53456,[email protected]:53456,[email protected]:26656,[email protected]:26656" && \
SEEDS="[email protected]:26656,c28827cb96c14c905b127b92065a3fb4cd77d7f6@testnet-seeds.whispernode.com:25756" && \
sed -i \
    -e "s/^seeds *=.*/seeds = \"$SEEDS\"/" \
    -e "s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" \
    "$HOME/.initia/config/config.toml"

Set min gas price

sed -i -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.15uinit,0.01uusdc\"/" $HOME/.initia/config/app.toml

Create a service file

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

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

[Install]
WantedBy=multi-user.target
EOF

Start the node

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

State sync

1. Stop the node

sudo systemctl stop initiad

Backup priv_validator_state.json

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

Reset DB

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

Setup required variables (One command)

PEERS="a63a6f6eae66b5dce57f5c568cdb0a79923a4e18@peer-initia-testnet.trusted-point.com:26628" && \
RPC="https://rpc-initia-testnet.trusted-point.com:443" && \
LATEST_HEIGHT=$(curl -s --max-time 3 --retry 2 --retry-connrefused $RPC/block | jq -r .result.block.header.height) && \
TRUST_HEIGHT=$((LATEST_HEIGHT - 1500)) && \
TRUST_HASH=$(curl -s --max-time 3 --retry 2 --retry-connrefused "$RPC/block?height=$TRUST_HEIGHT" | jq -r .result.block_id.hash) && \

if [ -n "$PEERS" ] && [ -n "$RPC" ] && [ -n "$LATEST_HEIGHT" ] && [ -n "$TRUST_HEIGHT" ] && [ -n "$TRUST_HASH" ]; then
    sed -i.bak \
        -e "/\[statesync\]/,/^\[/{s/\(enable = \).*$/\1true/}" \
        -e "/^rpc_servers =/ s|=.*|= \"$RPC,$RPC\"|;" \
        -e "/^trust_height =/ s/=.*/= $TRUST_HEIGHT/;" \
        -e "/^trust_hash =/ s/=.*/= \"$TRUST_HASH\"/" \
        -e "s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" \
        $HOME/.initia/config/config.toml
    echo -e "\nLATEST_HEIGHT: $LATEST_HEIGHT\nTRUST_HEIGHT: $TRUST_HEIGHT\nTRUST_HASH: $TRUST_HASH\nPEERS: $PEERS\n\nALL IS FINE"
else
    echo -e "\nError: One or more variables are empty. Please try again or change RPC\nExiting...\n"
fi

Move priv_validator_state.json back

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

Start the node

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

if node doesn't display like this

2:39PM INF sync any module=statesync msg="Discovering snapshots for 15s" server=node
2:39PM INF Discovered new snapshot format=3 hash="?^��I��\r�=�O�E�?�CQD�6�\x18�F:��\x006�" height=602000 module=statesync server=node
2:39PM INF Discovered new snapshot format=3 hash="%���\x16\x03�T0�v�f�C��5�<TlLb�5��l!�M" height=600000 module=statesync server=node
2:42PM INF VerifyHeader hash=CFC07DAB03CEB02F53273F5BDB6A7C16E6E02535B8A88614800ABA9C705D4AF7 height=602001 module=light server=node

you should use snapshots before you use snapshots, please stop your node

snapshots

before use snapshots. you need stop your node

Stop the service and reset the data

sudo systemctl stop initiad.service
cp $HOME/.initia/data/priv_validator_state.json $HOME/.initia/priv_validator_state.json.backup
rm -rf $HOME/.initia/data

Download latest snapshot

curl -L https://snapshots.kzvn.xyz/initia/initiation-1_latest.tar.lz4 | tar -Ilz4 -xf - -C $HOME/.initia
mv $HOME/.initia/priv_validator_state.json.backup $HOME/.initia/data/priv_validator_state.json

wait to finish

Restart the service and check the log

sudo systemctl restart initiad.service && sudo journalctl -u initiad.service -f --no-hostname -o cat

after all create your wallet

 initiad keys add wallet

Request tokens from the faucet on Discord

-> FAUCET <-

Check wallet balance

initiad status | jq -r .sync_info

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

Create a validator

initiad tx mstaking create-validator \
--amount 1000000uinit \
--pubkey $(initiad tendermint show-validator) \
--moniker "YOUR_MONIKER_NAME" \
--identity "YOUR_KEYBASE_ID" \
--details "YOUR_DETAILS" \
--website "YOUR_WEBSITE_URL" \
--chain-id initiation-1 \
--commission-rate 0.05 \
--commission-max-rate 0.20 \
--commission-max-change-rate 0.05 \
--from wallet \
 --gas=2000000 --fees=300000uinit \
--node https://rpc.dinhcongtac221.fun/ \
-y

conglatulation. now your validator finished

P.S. if you don't have keybase you can create with following this guide keybaseguide
