These are some of the key features of Equihash algorithm-

• This algorithm is designed to keep mining from becoming overly centralized. Equihash mining is complex due to the relatively low efficiency of ASICs.
• It provides a small resolution, yet difficult cryptographic test to construct. It helps to increase the overall scalability of the network by preventing massive cryptographic test traffic from overwhelming the system.
• The test requires a large amount of memory, which means that even after optimization, mining with ASIC, GPU and CPU is expensive.
• It is very versatile and can support future structural and algorithmic advances.
