What happens if someone asks for a refund after a transaction?

The app will operate much like e-transfer where once both members, the buyer and the seller, agree to the refund amount, the BITS™ can be sent back to the original buyer. So in this case, the seller, who originally received the BITS™, simply sends the BITS™ back to the original buyer. This is a matter that will be resolved by the two parties involved in the original transaction.
