We initialize the node to create the necessary configuration files
junctiond init UTSA_guide --chain-id junction
wget -O $HOME/.junction/config/genesis.json "https://raw.githubusercontent.com/111STAVR111/props/main/Airchains/genesis.json"

At this stage, we can download the address book
wget -O $HOME/.junction/config/addrbook.json "https://share102.utsa.tech/airchains/addrbook.json"
