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 and Become Oracle Provider​

Yoda contains multiple reporters. You will need to register the reporters to help the validator submit transactions of reporting data.

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

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

Secondly, register reporters to the validator, so that oracle requests for validator can be assigned to the reporters.

bandd tx oracle add-reporters $(yoda keys list -a) \
  --from $WALLET_NAME \
  --chain-id $CHAIN_ID

Finally, activate the validator to become an oracle provider

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

If all procedures are successful, then the oracle 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.
