The strategy described has completely nothing to do with Bitcoin or blockchain exploits. It seems to be exploiting a badly designed fee system, which permits a person to unilaterally cancel a fee by altering the timezone.

This leads the fee processor to assume an excessive amount of time has elapsed (many fee processors impose a time restrict by which a deposit should be made to keep away from value fluctuations and different points). Per regular process for an expired bill, any fee is refunded to the person.

The location talked about within the hyperlink seems to credit score the person no matter whether or not an bill is expired or not. That is completely the fault of a poor system design/integration between the fee processor and the integrating web site, and exploits completely nothing within the Bitcoin protocol, node software program, or pockets implementations.

It is mainly the equal of you promoting me one thing for $100 on the situation that I pay you inside 10 minutes, and cancelling our transaction as a result of I confirmed you the time on my cellphone (which I can change as I wish to) which signifies greater than 10 minutes has handed. Then, you refund me $100 if I pay you (because you assume the transaction is cancelled), however your accountant considers it full and ships out the products anyhow.
