Title: what is the screen telling me Post by: sid8ball on September 27, 2014, 03:56:59 PM This is the screen shot of my current cgminer which is solo mining. I was originally in a pool which made sense. going alone not so much. Can Someone explain the best share and difficulty on the screen and the block accepted. http://i61.photobucket.com/albums/h71/sid8ball/mining.png Title: Re: what is the screen telling me Post by: Wusolini on September 27, 2014, 04:45:06 PM best share:
Mining works by hashing a bunch of transaction information over and over (millions of hashes per second), slightly changing a few pre-determined variables each time to get a brand new hash, and then comparing all of the resulting hashes to see if one of them fits a certain set of criteria, called the difficulty. When a hash succeeds in this, the resulting hash will have a difficulty of 1 (or higher), and is now considered a "share", as we can submit this share to a pool. Shares can vary in their difficulty. It's sort of like drawing straws (http://en.wikipedia.org/wiki/Drawing_straws) with a bunch of different length straws: you never know how short the straw you're going to draw next is. The shorter the straw, the higher the difficulty, in our analogy. A share can have a difficulty of 1, 2 (twice has hard to find), 10 (10x harder), or 8,385,298 (8,385,298x harder to find). I don't know of any limit to how high the difficulty can go, but it gets incredibly harder to find higher difficulty shares. A block is found when a share's difficulty is higher than the network difficulty. At the time of this writing, that's about 19.3million. All of those diff=1 shares you submit to your pool don't actually count for anything, except to prove to the pool that you're actually working on finding a block (share with diff>19.3M) for the pool. Your "Best Share" is just a number to see how close you've come to finding a block. It's all completely random, so you could come back and find your GPU solved a block, or you could come back in a month and see you've never found anything higher. It's more of a fun, interesting number that doesn't really mean anything. My 7970 in my desktop has a best share of 19.5K. If that were back in Jan of 2011 (https://docs.google.com/spreadsheet/ccc?key=0AmcTCtjBoRWUdHVRMHpqWUJValI1RlZiaEtCT1RrQmc#gid=0), that would have been higher than the Network Difficulty, and it would have been a block solver. Now, it's nowhere close. Hope this helped answer your question. Difficulty: - https://en.bitcoin.it/wiki/Difficulty or try some search in OFFICIAL CGMINER mining software thread...

Zero rewards in solo mining unless you find a block. They're purely an estimate of how hard you're trying. |
