I know there's transaction fees etc, but I read about 'Change' as well, is this something different? See below for what it was defined as:
Here's a better example:
Lets say you are paying for a $21 meal at a restaurant. You pull a $20 bill out of your wallet. You search your wallet further and find a $10 bill. You give both bills to your waiter. The waiter rings $21 into the till, pockets $4 as a tip, and gives you $5 as change. The $20 and $10 were inputs. The $21 was an output to your payee. The $5 is a change output returned to you for use in a future transaction. And $4 was consumed as a service charge.
Thanks
