🚨 Maintenance

Get validator info

c4ed status 2>&1 | jq .ValidatorInfo

Get sync info

c4ed status 2>&1 | jq .SyncInfo

Get node peer

echo $(c4ed tendermint show-node-id)'@'$(curl -s ifconfig.me)':'$(cat $HOME/.c4e/config/config.toml | sed -n '/Address to listen for incoming connection/{n;p;}' | sed 's/.*://; s/".*//')

Check if validator key is correct

[[ $(c4ed q staking validator $(c4ed keys show wallet --bech val -a) -oj | jq -r .consensus_pubkey.key) = $(c4ed status | jq -r .ValidatorInfo.PubKey.value) ]] && echo -e "\n\e[1m\e[32mTrue\e[0m\n" || echo -e "\n\e[1m\e[31mFalse\e[0m\n"

Get live peers

curl -sS http://localhost:26657/net_info | jq -r '.result.peers[] | "\(.node_info.id)@\(.remote_ip):\(.node_info.listen_addr)"' | awk -F ':' '{print $1":"$(NF)}'

Set minimum gas price

sed -i -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0uc4e\"/" $HOME/.c4e/config/app.toml

Enable prometheus

sed -i -e "s/prometheus = false/prometheus = true/" $HOME/.c4e/config/config.toml

Reset chain data

c4ed tendermint unsafe-reset-all --home $HOME/.c4e --keep-addr-book

Remove node

Please, before proceeding with the next step! All chain data will be lost! Make sure you have backed up your priv_validator_key.json!
