Okay makes sense. So to obtain a block my difficulty must surpass the base difficulty of the block and for that to happen is entirely by chance/luck. When a share is expected, that doesn't mean a block is mined but means that the minimum mining diff was surpassed and a share was accepted by the pool in an attempt to mine the block. Sorry if I'm being an inconvenience, I'm trying to learn about it. I'm curious, how can you tell if you mined a block, Eth or BTC or any to be frank.

i was mining with the SHA256 on ck pool. And my diff showed as 11.7k over 10k meaning that there was a block mined or I'm missing some crucial piece of information.

I need help understanding what happened on my BFGminer. I'm experimenting with crypto and getting into ETH mining. But I have a usb block erupter i was toying with and trying to see if I can get it to script mine. But I left the bfg miner for ck pool running just for the hell of it and I ended up getting an accepted share which I have no idea what it is. My Efficiency reads at 12.66 and my Accepted share is at 1.
