Hi all,
i see that there are some estimations on difficulty value in chart posted on
http://bitcoin.sipa.be/. And also many APIs they all provide estimated difficulty values. i want to know their formula, is there an unanimous formula or they use their own private methods? I know how to calculate next difficulty based on previous 2016 blocks, however, it seems that
http://bitcoin.sipa.be/ has some tricky estimation which take 3-day/7-day window. I really want to know the details.
Any explanation is appreciated! BTW, im a newbie here, if i post this thread in a incorrect manner, please kindly let me either.
