- false minting (spending non-existant output)
-- This requires UTXO commitments

- Invalid UTXO commitments

UTXO commitments are not required for proving one of those kinds of fraud, apparently:

"You do them without a UTXO commitment by instead committing to the input block and offset that the input came from. Then fraud can be proven by simply showing whatever is at that location, if its not the thing its supposed to be."
