A9 ZMaster ASIC Available to Help Zcash Decentralization

Innosilicon is the industry leader in designing and manufacturing specialized cryptography ASICs that are required for Proof-of-Work blockchains such as Bitcoin, ZCash, Litecoin, Decred and other leading digital currencies.

The new A9 Zmaster ASIC (also referred to as A9 Zmaster) is a simple to use, highly optimized GPU like ASIC hardware designed specifically for the purpose of the equihash with the highest power efficiency to-date. It is developed in the most advanced process nodes with very innovative architecture and low power consumption. A9 Zmaster is highly integrated GPU like solution using very few external components. It is extremely easy to use and easy to deploy in large scale with low cost.

With sophisticated on chip ADC and dynamic temperature and frequency scaling for highly reliable performance under all conditions, the A9 Zmaster has operation modes from low power to over clock high performance through adjustment of PLL output clock frequency and/or in combination with voltage adjustment. It is up to the miner manufacturers to decide what speed and power efficiency they design the miners for and/or whether it is configurable.
