Is DGW susceptible to this exploit? I thought that it was made in response to this exploit being found.
EDIT - I misread the above quote. I was not talking about DGW - Dark Gravity Wave... but was discussing KGW - Kimoto Gravity WaveThere is substantial evidence that
DGW KGW is susceptible to this exploit, but that does not mean that KDC is necessarily in danger. In fact, it would take significantly more effort to attack KDC with the
DGW KGW exploit than to mount a good, old fashioned 51% attack.
The
DGW exploit is only attractive when targeting a high difficulty, high hash-rate network where a 51% attack would be impossible or nearly so, because the
DGW KGW exploit only requires about 20% of the network hash-rate to be effective. So yes, someone could attack KDC using 9Mh/s(20% of 48Mh/s), but extremely unlikely as it would be simpler and more effective to just mount a 51% attack.
The whole
DGW KGW exploit is a false 'panic button' being pushed at the moment.
Does a
DGW KGW fix need to be deployed... yes... but there is no real rush. It was critical for AUR and POT as those coins are becoming active trading pairs for many coins, especially in the wake of the Cryptorush debacle where POT was one of the primary coins used to liquidate frozen BTC and LTC wallets.
