We will not implement GPU miner, if third-party developers wish to implement it, then they can do this. But, if there'll be GPU-miner, that is more than twice as effective on todays GPUs, as CPU-miners on todays CPUs, and especially if there'll be ASIC developed for Binarium, then we'll implement new hashing algorithm, that 'll be more hard for GPUs and ASICs, while keeping current consensus of network.
