I still don't fully understand mining, so pardon my ignorance if this has been answered or addressed already, or if this is in the wrong thread. Thanks for any insight into the issue. I use Slush pool as my primary BTC mining pool, and I currently run 2 underclocked Antminer S1's on the pool at 130 GH/s. As far as I know, Slush pool DOES NOT merge mine any alt coin of sorts, so this is where my problem arises... I know that the Bitcoin network difficulty is at 47427554950 and I would need a "BestShare" greater than that number to find a block. One of my Antminer S1's report a "FoundBlock" and this isn't the first time this has happened at Slush pool for me, however my "BestShare" is only 66,379,851... My main questions are: Why does this happen? Does Slush actually merge mine and just not tell the users? Is my Antminer S1 just being glitchy? Does the "1" under "Stale" explain this? I did a little bit of research and the only altcoin that I found that can be merge mined with BTC AND has a difficulty below 66,379,851 is i0coin... Did my miner find an i0coin block, because it is possible to "merge mine" with Bitcoin? Here is an image for reference:



Thanks again for any help!
