Title: Miner device that maxes out at 100 difficulty?
Post by: bitpop on June 16, 2013, 01:32:20 AM
Is it possible and cheaper to make a device that only finds <100 difficulty shares? If it's cheaper or easier, you could mine at pools all you want and get full payout. But I'm sure I'm missing something.

No, see:

At best you shave a couple percent off at the end.

I don't understand that, I'm still stuck getting php to accept my iv. But let me put it this way. If current difficulty is 15.6m, is my miner always making hashes that long but the diff 1 or whatever is when it made one with only 1 0?

Or is it making tiny hashes somehow. How does it even get to 15.6m digits with sha256 which is much shorter.

Can you show me exactly a diff 10 and a 15.6 from start to finish? In pseudo code like sha256(coinz)..

I'm sorry, but this has been discussed millions of times. Please search the forums.
