THIS!What about the possibility that the alleged botnet you mentioned was in fact secret ASIC mining?
this has got me thinking, and someone said ASIC is like cancer to miners, i am starting to agree that maybe we should talk about changing something to at least resist large hash centralization somehow if its not changing the algorithm. as a miner i paid attention to global hash and i would watch the hash rates rise and drop sometimes 50% and blocks would take much longer to confirm. i changed my view when i realized i would be allowing dash creation centralization. I felt it should be against my naturally decentralized view to want to allow this to be out of the reach of more people. This is the problem how do we keep mining decentralized while allowing the technology to grow...
