If you haven't read, Bitmain has introduced an ASIC Miner that will dwarf current GPU miners. Their initial product is kind of pathetic at 180Mh/s for 800W, but rumors are they have a 1,500GH/s miner with not much more power usage already completed and being used internally until they decide to sell them.
ASIC stands for Application-specific integrated circuit and refers to hardware that is designed with one specific purpose and does that purpose very well compared to current technology. In the mining industry, this means hardware that can perform extremely efficiently on one hashing algorithm gaining a huge advantage on hash rate per kwh of power used.
Ethereum has always declared itself as ASIC resistant and will likely create a hard fork to prevent the launch of ASIC devices. Vitalik Buterin claims the second line of defense for Ethereum is to "poison the well" to prevent the release of ASIC devices.
Currently 57% have responded to a recent poll in favor of a hard fork to prevent ASIC mining. Unfortunately, it is highly likely Bitmain is currently mining with these devices and considerably more powerful devices in secret. They have been accused of this many times and in fact is so lucrative it is hard to imagine they are not already.
Would you support a hard fork to prevent ASIC devices from having an unfair advantage or should any resource available be used if you have the power to create it?
