WTEMA

WTEMA (Weighted-target Exponential Moving Average) is the DAA (Difficulty Adjustment Algorithm) used by STILL.

Why WTEMA?

WTEMA is a close approximation of the ASERT difficulty algorithm, without floating-point math emulation requirements. After multiple researches and simulations on several DAA algorithms, ASERT/WTEMA have resulted to be the best under several scenarios. The simplicity and effectiveness of the WTEMA algorithm made it the ideal choice as a STILL blockchain DAA.
