Also, like I pointed out earlier, this means that Masternodes now have no direct involvement in the actual person to person transaction, so if someone decides to use Darkcoin to so something illegal, there is no reasonable grounds for Masternode owners to be held liable.
Plausible deniability ftw!
As someone pointed out above, of course, aways consult your attorney.
That said, I'm not sure it's just plausible deniability. Once this is implemented, Masternodes will simply be denominating funds. They will no longer be facilitating the actual transfer of funds for purchases between a buyer and a seller. They are completely bypassed in that regard.
If the United States government gets a hint that a one cent of funds was transferred to any terrorist organization using the Darkcoin network it's lights out. Plausible deniability doesn't mean a thing when Amazon and every other provider in the United States complies with a court order and shuts down the masternodes.
I'm not promoting cryptonote coins as they have plenty of their own problems. But they offer true P2P anonymity that isn't subject to having a masternode network shut down.
