Become a Validator

This guide will show you how to register the running node as a validator. So that the program can fulfill the data on BandChain.

Step 1: Fund the Validator Account​

bandd keys show $WALLET_NAME

Then fund tokens into this account ready for staking.

Step 2: Stake Tokens with the Validator Account​

bandd tx staking create-validator \
    --amount 1000000uband \
    --commission-max-change-rate 0.01 \
    --commission-max-rate 0.2 \
    --commission-rate 0.1 \
    --from $WALLET_NAME \
    --min-self-delegation 1 \
    --moniker "$MONIKER" \
    --pubkey $(bandd tendermint show-validator) \
    --chain-id $CHAIN_ID

Registered validators can be found on CosmoScan.

Step 3: Register Reporters & Feeders and Become Data Provider​

You will need to register Reporters and Feeders to help the validator submit transactions of reporting data.

Firstly, reporter and feeder accounts must be created on BandChain by supplying a small amount of BAND tokens.

# Send 1uband from a wallet to each reporter.
bandd tx bank multi-send $WALLET_NAME $(yoda keys list -a) 1uband \
  --chain-id $CHAIN_ID \
  --gas 400000
# Send 1uband from a wallet to each feeder.
bandd tx bank multi-send $WALLET_NAME $(grogu keys list -a) 1uband \
  --chain-id $CHAIN_ID \
  --gas 400000

Secondly, register reporters and feeders to the validator, so that they can send transactions for the validator.

bandd tx oracle add-reporters $(yoda keys list -a) \
  --from $WALLET_NAME \
  --chain-id $CHAIN_ID \
  --gas 400000
bandd tx feeds add-feeders $(grogu keys list -a) \
  --from $WALLET_NAME \
  --chain-id $CHAIN_ID \
  --gas 400000

Finally, activate the validator to become a data provider

bandd tx oracle activate \
  --from $WALLET_NAME \
  --chain-id $CHAIN_ID

If all procedures are successful, then the data provider status for the validator should be active.

bandd query oracle validator $(bandd keys show -a $WALLET_NAME --bech val)

# {
#   "is_active": true,
#   "since": ...
# }

And now you have become a validator on BandChain Laozi mainnet.
