Node installation
git clone https://github.com/chain4energy/c4e-chain && cd c4e-chain
git checkout v1.4.2
make install
c4ed version --long | grep -e version -e commit
# 1.4.2
# commit: b842f471290e5e4b5a1f3bf67e4afd6574f54f61
We initialize the node to create the necessary configuration files
c4ed init UTSA_guide --chain-id perun-1
Download Genesis
wget -O $HOME/.c4e-chain/config/genesis.json "https://raw.githubusercontent.com/chain4energy/c4e-chains/main/perun-1/genesis.json"
# check genesis
sha256sum ~/.c4e-chain/config/genesis.json

At this stage, we can download the address book
wget -O $HOME/.c4e-chain/config/addrbook.json "https://share.utsa.tech/c4e/addrbook.json"
