Step 4: Init your keys and download genesis file

liked init <moniker>
liked keys add <keyname>
curl https://raw.githubusercontent.com/likecoin/mainnet/master/genesis.json > ~/.liked/config/genesis.json

Step 5: Set up minimum gas price

sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"10000nanolike\"/;" ~/.liked/config/app.toml

Step 6: Set up pruning (optional)

pruning="custom"
pruning_keep_recent="100"
pruning_keep_every="0"
pruning_interval="10"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.liked/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.liked/config/app.toml
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" $HOME/.liked/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.liked/config/app.toml
