@hilarski for mining it uses the same equihash algorithm as zcash which is somewhat memory intensive.
That makes it much less cost effective to design an ASIC for it especially since the GPU guys will be designing 10 nm and 7nm GPUs in the next few years.
Designing and producing ASICs at those small feature sizes is very expensive. So I expect there will probably not be an ASIC miner for ZenCash for a long time, if ever.
