Title: cgminer "networking diff" vs official difficulty Post by: fxj on July 06, 2013, 11:36:45 AM Hi,
when firing up cgminer I get "networking diff" so and so, but this figure is so much larger than the listed difficulty. For instance, cgminer shows "network diff" of 9.02M when mining for Feathercoins @ coinotron. Whereas the listed current difficulty for Feathercoin is 137.632 according to coinchoose.com. I have looked around for information on this, but have not came across anything yet. Can someone here enlighten me, or point me in the right direction?

Without going into too much detail the official difficulty is relative to the entire hash rate of the network so that a block will be found every x minutes. Smaller pools use a lower difficulty because the rounds are much longer.

your reply helped me find this: https://bitcointalk.org/index.php?topic=220341.0 (see initial post of that thread) What happens is that cgminer multiplies official difficulty by 65536 [or 2^16]. Testing on my own numbers: 137.632 * 65 536 = 9.02M Title: Re: cgminer "networking diff" vs official difficulty Post by: YOLOSWAG420HASHTAG on July 06, 2013, 04:50:30 PM Thanks Yoloswag, NP, I'm not 100% sure that FTC works exactly like ltc but it should be similar in that they both use the salsa208 your reply helped me find this: https://bitcointalk.org/index.php?topic=220341.0 (see initial post of that thread) What happens is that cgminer multiplies official difficulty by 65536 [or 2^16].
