Both sides elect a commitment fee, and the lowest is chosen. That means you can't game the other side (but if you offer too low, then can error out of course). Fees are split 50-50 if possible: originally the whole fee has to be paid by the (single) funder. Neither side can withdraw funds which would make them unable to pay fees.
