Isn't that effectively the GHash situation? Small number of nodes feeding large number of miners. Controls hash but not network. Or were you thinking a p2pool setup? Anyway I wanted to investigate owning network and what effect that could have.
Yes, it is. Ghas situation. Do you job, do it great, and you get ability to attack network basicly for free, or even get payed for it (GHash is making crazy amount of money). When i see how people are dreaming of other kind of attacks, it's just funny. Like anyone needs to invest into hash power....how silly is that
