    Install go

    We are gonna use GO Version 1.21.7 If you already have GO installed you can skip this

    ver="1.22.5"
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

    Install binary

    wget https://github.com/airchains-network/junction/releases/download/v0.3.1/junctiond-linux-amd64  
chmod +x junctiond-linux-amd64  
mv junctiond-linux-amd64 /usr/local/bin/junctiond

    Verify that you’ve installed Warden successfully

    junctiond version --long | grep -e commit -e version

    Initialize Node

    Please change <MONIKER> To your own Moniker.

    junctiond init <MONIKER> --chain-id varanasi-1

    Download Genesis file and addrbook

    • Genesis
    curl -L https://snap-t.vinjan.xyz/junction/genesis.json  > $HOME/.junctiond/config/genesis.json
    • Addrbook
    curl -L https://snap-t.vinjan.xyz/junction/addrbook.json > $HOME/.junctiond/config/addrbook.json

    Configure Peers and Gas

    peers="$(curl -sS https://rpc-airchain.vinjan.xyz:443/net_info | jq -r '.result.peers[] | "\(.node_info.id)@\(.remote_ip):\(.node_info.listen_addr)"' | awk -F ':' '{print $1":"$(NF)}' | sed -z 's|\n|,|g;s|.$||')"
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" $HOME/.junctiond/config/config.toml
sed -i -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0uamf\"/" $HOME/.junctiond/config/app.toml

    config pruning

    sed -i \
-e 's|^pruning *=.*|pruning = "custom"|' \
-e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \
-e 's|^pruning-keep-every *=.*|pruning-keep-every = ""|' \
-e 's|^pruning-interval *=.*|pruning-interval = "50"|' \
$HOME/.junctiond/config/app.toml

    create service file and start node

    Create service file Create a wardend.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/junctiond.service > /dev/null <<EOF
[Unit]
Description=junction
After=network-online.target

[Service]
User=$USER
ExecStart=$(which junctiond) start
