Why is people still mining this with 35% profitability compared to LTC?
Obviously you haven't seen this or you wouldn't even be asking that:
Darkcoin mining profitability model.
The algorithm begins with the n+1 bit state
. That is, the first n bits are each in the state
and the final bit is
. A Hadamard transformation is applied to each bit to obtain the state
We have the function f implemented as quantum oracle. The oracle maps the state
, where
is addition modulo 2 (see below for details of implementation). Applying the quantum oracle gives
For each x, f(x) is either 0 or 1. A quick check of these two possibilities yields
At this point the last qubit may be ignored. We apply a Hadamard transformation to each qubit to obtain
where
is the sum of the bitwise product.
Finally we examine the probability of measuring
which evaluates to 1 if f(x) is constant (constructive interference) and 0 if f(x) is balanced (destructive interference).
