You say that you want to make patented optimiz= ation useless, but you point to a link that doesn't say anything about = ASIC improvements or patents, which means that you have been planning to ch= ange the protocol rules with some miners (but not all the community).=C2=A0=

All c= hanges to the protocol should be discussed in public here. If you want to m= ake "further similar optimizations useless as well" then maybe yo= u should propose a switch to EquiHash.
