    Guys, review this - https://bt.irlbtc.com/view/316104.0 - plz. I don't want to implement it and then see that the idea is flawed. Would be great if u did it ASAP.

    I'm trying to wrap my mind on the following:

    Quote from: BCNext
    Someone still can attempt a double-spending by paying for something with low fee and then sending all their coins to other account with higher fee, making it impossible to confirm the first payment.

    Since the second transaction has a higher fee, it will get on the next block with higher priority, right? Since the first payment won't be confirmed, how can the double-spend succeed?

    If the merchant has already given you the requested item and after that the first transaction get lost/reverted/etc. (because you spend the money somewhere else) we talk about a double-spend.
