    cd $HOME
git clone https://github.com/ojo-network/ojo.git
cd ojo
git checkout v0.1.2
make install

    Verify that you’ve installed ojod successfully

    ojod version

    Initialize Node

    Please change <MONIKER> To your own Moniker.

    ojod init $MONIKER --chain-id ojo-devnet
ojod config chain-id ojo-devnet
ojod config keyring-backend test

    Download Genesis file and addrbook

    • Genesis
    curl -s https://rpc.devnet-n0.ojo-devnet.node.ojo.network/genesis | jq -r .result.genesis > $HOME/.ojo/config/genesis.json
    • Addrbook
    wget -O $HOME/.ojo/config/addrbook.json "https://raw.githubusercontent.com/vinjan23/Testnet.Guide/main/Ojo/addrbook.json"

    create service file and start node

    Create service file Create a ojod.service file in the /etc/systemd/system folder with the following code. You can change USER with your Linux user name. You need sudo previlege to do this step.

    sudo tee /etc/systemd/system/ojod.service > /dev/null <<EOF
[Unit]
Description=ojod
After=network-online.target

[Service]
User=$USER
ExecStart=$(which ojod) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF
    • Enable Service and Start Node
    sudo systemctl daemon-reload
sudo systemctl enable ojod
sudo systemctl restart ojod
sudo journalctl -fu ojod -o cat
