Cheat Sheet

A Tendermint cheat sheet is a quick reference for essential commands to control Tendermint blockchains.

Managing keys

Managing keys on a Tendermint-based chain involves securing and controlling access to cryptographic keys used for chain operations.

Generate new key

bcnad keys add wallet

Recover key

bcnad keys add wallet --recover

List all key

bcnad keys list

Delete key

bcnad keys delete wallet

Export key

bcnad keys export wallet

Import key

bcnad keys import wallet wallet.backup

Query wallet balances

bcnad q bank balances $(bcnad keys show wallet -a)

Managing validators

Ensure you've updated moniker, identity, details, and website to match your values.

Create validator

bcnad tx staking create-validator \
--amount 1000000ubcna \
--pubkey $(bcnad tendermint show-validator) \
--moniker "your-moniker-name" \
--identity "your-keybase-id" \
--details "your-details" \
--website "your-website" \
--security-contact "your-email" \
--chain-id bitcanna-1 \
--commission-rate 0.05 \
--commission-max-rate 0.20 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--from wallet \
--gas-adjustment 1.4 \
--gas auto \
--fees 0ubcna \
-y

Edit validator

bcnad tx staking edit-validator \
--new-moniker "your-moniker-name" \
--identity "your-keybase-id" \
--details "your-details" \
--website "your-website" \
--security-contact "your-email" \
--chain-id bitcanna-1 \
--commission-rate 0.05 \
--from wallet \
--gas-adjustment 1.4 \
--gas auto \
--fees 0ubcna \
-y

Unjail validator

bcnad tx slashing unjail --from wallet --chain-id bitcanna-1 --gas-adjustment 1.4 --gas auto --fees 0ubcna -y

Validator jail reason

bcnad query slashing signing-info $(bcnad tendermint show-validator)

List active validator

bcnad q staking validators -oj --limit=3000 | jq '.validators[] | select(.status=="BOND_STATUS_BONDED")' | jq -r '(.tokens|tonumber/pow(10; 6)|floor|tostring) + " \t " + .description.moniker' | sort -gr | nl

List incative validator

bcnad q staking validators -oj --limit=3000 | jq '.validators[] | select(.status=="BOND_STATUS_UNBONDED")' | jq -r '(.tokens|tonumber/pow(10; 6)|floor|tostring) + " \t " + .description.moniker' | sort -gr | nl

View validator details

bcnad q staking validator $(bcnad keys show wallet --bech val -a)

Managing Tokens

Withdraw reward from all validator

bcnad tx distribution withdraw-all-rewards --from wallet --chain-id bitcanna-1 --gas-adjustment 1.4 --gas auto --fees 0ubcna -y

Withdraw reward and commission

bcnad tx distribution withdraw-rewards $(bcnad keys show wallet --bech val -a) --commission --from wallet --chain-id bitcanna-1 --gas-adjustment 1.4 --gas auto --fees 0ubcna -y

Delegate tokens to your validator

bcnad tx staking delegate $(bcnad keys show wallet --bech val -a) 1000000ubcna --from wallet --chain-id bitcanna-1 --gas-adjustment 1.4 --gas auto --fees 0ubcna -y

Delegate token to other validator, change <to-valoper-address> as you like

bcnad tx staking delegate <to-valoper-address> 1000000ubcna --from wallet --chain-id bitcanna-1 --gas-adjustment 1.4 --gas auto --fees 0ubcna -y

Redelegate to another validator

bcnad tx staking redelegate $(bcnad keys show wallet --bech val -a) <to-valoper-address> 1000000ubcna --from wallet --chain-id bitcanna-1 --gas-adjustment 1.4 --gas auto --fees 0ubcna -y

Unbond token from your own validator

bcnad tx staking unbond $(bcnad keys show wallet --bech val -a) 1000000ubcna --from wallet --chain-id bitcanna-1 --gas-adjustment 1.4 --gas auto --fees 0ubcna -y

Send token to the wallet

bcnad tx bank send wallet <to-wallet-address> 1000000ubcna --from wallet --chain-id bitcanna-1 --gas-adjustment 1.4 --gas auto --fees 0ubcna -y

Governance

Usefulness

Please note that updating the custom port is optional!

Update custom port

CUSTOM_PORT=117
sed -i -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:${CUSTOM_PORT}58\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:${CUSTOM_PORT}57\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:${CUSTOM_PORT}60\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:${CUSTOM_PORT}56\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":${CUSTOM_PORT}66\"%" $HOME/.bcna/config/config.toml

Disable indexer

sed -i -e 's|^indexer *=.*|indexer = "null"|' $HOME/.bcna/config/config.toml

Enable indexer

sed -i -e 's|^indexer *=.*|indexer = "kv"|' $HOME/.bcna/config/config.toml

Pruning update

sed -i \
  -e 's|^pruning *=.*|pruning = "custom"|' \
  -e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \
  -e 's|^pruning-keep-every *=.*|pruning-keep-every = "0"|' \
  -e 's|^pruning-interval *=.*|pruning-interval = "19"|' \
  $HOME/.bcna/config/app.toml

Maintenance

Get validator information

bcnad status 2>&1 | jq .ValidatorInfo

Get sync information

bcnad status 2>&1 | jq .SyncInfo

Get node peer

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

Check validator keys

[[ $(bcnad q staking validator $(bcnad keys show wallet --bech val -a) -oj | jq -r .consensus_pubkey.key) = $(bcnad 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:11757/net_info | jq -r '.result.peers[] | "\(.node_info.id)@\(.remote_ip):\(.node_info.listen_addr)"' | awk -F ':' '{print $1":"$(NF)}'

Configure minimum gas prices

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

Enable prometheus

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

Reset chain data

bcnad tendermint unsafe-reset-all --keep-addr-book --home $HOME/.bcna --keep-addr-book

🚨

Before moving on to the next step, be aware that all chain data will be erased. Ensure you've created a backup of your priv_validator_key.json!

Remove node

cd $HOME
sudo systemctl stop bitcanna
sudo systemctl disable bitcanna
sudo rm /etc/systemd/system/bitcanna.service
sudo systemctl daemon-reload
sudo rm -f $(which bcnad)
sudo rm -rf $HOME/.bcna
sudo rm -rf $HOME/bcna
sudo rm -rf $HOME/go
