No.

I've been wondering about this too.
How do you prevent rouges setting up hundreds of nodes that collect data about transactions, without a financial barrier to disrupt the network and create many men in the middle sniffing transactions as they pass around ?
Yea, that's why DRK's masternodes are not an ideal solution... because it is a centralized solution.
around 750 masternodes right now, after rc4 and open source this number will double. That should happen by end of august.
if drk proves it is 100% anon and governments continue to pressure exchanges for id of users aswell as charge traders with a bitlicense.
more masternodes = more de-centralization
