| How many times has this been used in practice? Like really - did your friend owe you $200 and you wanted to make sure he couldn't pay you something over square and then call his credit company and say his card was lost? Like are you a shop online and you wanted to make sure ALL of your customers are paying in Bitcoin so they can't claim someone stole their card? Are you a party to a lawsuit and the judge decided to oversee the other party pay you (the fictitious plaintiff in this scenario) $50000 with a check and you're worried he's calling his bank afterward and cancel the check? None of these scenarios would be made better with Bitcoin: Transaction costs Some online stores ARE scams and it's better to have a real money trail - especially the ones involving bitcoin The last scenario is easily solved because the judge would be able to provide much harsher realities for the check canceller. From a practicality standpoint every time someone talks about irreversible transactions I just eyeroll at the actual logistics of that working in our world of 7B people. |
The first line of the whitepaper[0] is "A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another"
In practice some "third" party (bank, paypal, square, venmo, etc) will still be involved in most transactions because of the scenarios you have described. But this would be because they are helpful and add value not because they are necessary.
