Re: [ANN][XRB]Cryptocurrency's killer app: RaiBlocks micropayments
5. The Man in the Middle attack.
If an attacker succeeds to put himself between a merchant and the RaiBlocks network he can just filter the double spending payment packets, and the merchant will never know that he is receiving a double spending. The Raiblocks network will discard that payment while the merchant will accept it.

Couldn't the same MitM attack be used in a bitcoin transaction? Connect to all the peers of a merchant and mine 6 blocks containing the double spend while filtering out all longer blocks so the merchant accepts the transaction as valid.
No, because if you MITM a bitcoin merchant, you still have to mine 6 blocks with the difficulty bit set by the real network. And the difficulty only decrease by 1/4 every 2015 blocks. It will be impossible for an attacker to have such power.
These asshole fudders are using the fact that they have a little bit more technical knowledge then most of the non technical people to spread their FUD.
It isn't even their own knowledge - they scour these forums and the internet for comments that other people have already posted and have been dismissed ages ago.
In most cases they are direct copy and pastes. I know because I have been following Raiblocks for over a year so I recognize a lot of this FUD as word for word copies of old posts.
