Re: Bitcoin XT - Officially #REKT (also goes for BIP101 fraud)

It [Opt-in RBF] reduces the functionality of zero confirmation transactions.

Good! zero-conf was the definition of stupid when I got interested in Bitcoin, and with good reason.

I would like to preserve and strengthen zero confirmation transactions, like XT and Bitcoin unlimited have stated. There is a fundamental disagreement of believe here.

If I am a merchant should I reject RBF? Since if I did do this could cause other problems as well. Since it is the person that sends the transactions that chooses to opt in not the receiver.

Transfer your Bitcoin (in the unlikely event that you have any) to a wallet service which guarantees not to do RBF then and let them interact with vendors. Or just use ACH/PayPal if you like it so much. Many of the rest of use have use for something different.

I operate a brick and mortar store which accepts zero confirmation transactions directly, I would not like it if I would have to stop accepting Bitcoin or use a third party, which would mean I would then need to take down the Bitcoin sign I have in my store, I would still accept other cryptocurrencies of course. The blocksize would also be a factor in this, I do not agree with the path Core is taking Bitcoin into, fortunately we now do have alternative implementations to choose from and more are also now starting to appear.

You will not have to take down your Bitcoin sign, you can operate as before

Not when the blocks fill up rendering transactions unreliable and to expensive for the purchases made at that store, RBF certainly also does not help the situation.

There seems to be mixed responses about how damaging RBF will be to zero confirmation transactions, I suppose this will also depend on the extend of adoption of RBF. As far as I understand it however it will make double spends easier and therefore zero confirmation less secure and also therefore less reliable. While at the same time making Bitcoin less user friendly and more complex.
