```bash
sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.1untiv\"/;" ~/.gonative/config/app.toml
external_address=$(wget -qO- eth0.me) 
sed -i.bak -e "s/^external_address *=.*/external_address = \"$external_address:26656\"/" $HOME/.gonative/config/config.toml
peers=""
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" $HOME/.gonative/config/config.toml
seeds=""
sed -i.bak -e "s/^seeds =.*/seeds = \"$seeds\"/" $HOME/.gonative/config/config.toml
