Title: Mining solo with Network difficulty set to 16.6 M (but I am using doge)
Post by: zerodrama on December 20, 2013, 05:46:57 AM
Doge difficulty is 317. Why is cgminer setting net diff to 16.6 M when mining solo? Also getting lots of rejects. But not at pools.

It can't be 16.6M at diff 317.. it should be 317*65536 = 20.7M

Oh I see. Ok now that makes sense. So Net difficulty is expressed in shares, but coin difficulty is expressed in block difficulty?

for historical reasons Scrypt-based coins use different difficulty units. Where a block of Diff 1 requires 65536*65536 hashes in average to be solved.
And cgminer doesn't auto-convert that difficulty.
