Question

I'm trying to start a new node : https://github.com/cosmos/mainnet

It looks like I'm having some issue with gaiad start

after I Fetch the mainnet's genesis.json file into gaiad's config directory.

mkdir -p $HOME/.gaia/config
wget https://github.com/cosmos/mainnet/raw/master/genesis.cosmoshub-4.json.gz
gzip -d genesis.cosmoshub-4.json.gz
mv genesis.cosmoshub-4.json $HOME/.gaia/config

and start gaiad start

error.log:
