In the past, one of the slogans of the currency using the Ethash algorithm represented by ETH and the currency using the Equihash algorithm represented by Zcash is ANTI-ASIC, which has the ability to resist the appearance of ASIC chips.
Essentially, the principle of the two algorithms involved in the ANTI-ASIC capability is to use a memory demand type algorithm, that is, the need for a certain amount of RAM storage when computing.
In 2014 and 2015, the logic of “adopting memory requirement algorithm == ANTI-ASIC” was established, which was closely related to the cost of hardware manufacturing at that time. Over time, however, the price of RAM has fallen, resulting in a reduction in the cost of specialized mining machine with large amounts of RAM. Thus, there is today’s situation – all kinds of algorithms have been conquered by mining chip manufacturers, and the corresponding algorithm specialized mining machines are available.
Today we will do some popular science through the hardware disassembly of Antminer E3 and Z9: how are the ASIC chips of these algorithms different from the ASIC chips of old algorithms such as Bitcoin and Litecoin?
