From what I have read, an attack to the network does not need to be 51%. The likely hood to be succesfull with above 51% is higher. So it really depends on how you want to look at a secure network.
Ok then to make this truly secure, the 51% or higher, nethash would have to be controlled by asics owned and operated by Noblecoin... correct?
You don't have to answer.
The point I'm getting at is the asics mining equipment WOULD have to be owned and operated by Noblecoin.
If Noblecoin is mining >51% of all the coins, then they would have to sell the coins to support a continual upgrade cycle to insure they maintain >51%.
Just seems like a lot of time, money, headache invested just to stay ahead of the asics game, not to mention the community would demand accountability for the mined coins just like the pre-mine coins.
