Besides this, more importantly, each hash (ie difficulty of 1) has the same probability of solving the block as 1/1024 of a miner hashing at difficulty of 1024 (accepted share with difficulty 1024)?
Only a difficulty share 39.5 Billion or higher will solve the block at this difficulty level. A diff 1 has no chance of solving a block as it doesn't meet or exceed the current difficulty, neither will a diff 1024.

but I don't exactly see it that way because each mining node is competing against all the others.
There is no competition. Every hash found has an equal chance of matching or exceeding current difficulty, which is around 39.5 Billion. If there's no competition, then why am I not solving ALL of the blocks? Besides this, more importantly, each hash (ie difficulty of 1) has the same probability of solving the block as 1/1024 of a miner hashing at difficulty of 1024 (accepted share with difficulty 1024)? And when my miner has difficulty set, there are no accepted shares below that difficulty. So I'm assuming that 934/1024 doesn't show up, because it's not accepted. My understanding is that 1024 is a larger fraction of 39.5B to be solved. None of your shares count for anything unless they are a block. Flooding the server with hundreds of shares per second that count for nothing would be a bad design. Using a difficulty is - as already stated - simply to show your hash rate in cgminer. A person with 1PHs (1,000 THs) would expect to find on average "about" one block every 2 days. It may be 1 minute, it may be 20 days. 2 days is just an average expected value for 1,000THs Also note that 1PHs would be ~14 million 1diff shares a minute. Yeah that would be a really bad idea to send that to any computer ... instead you'd send ~20 ~700,000 diff shares a minute. Same result, either one finding a block would still submit the block, but if it was 14,000,000/minute there's also the fact that the pool would die for various reasons (network, CPU) and you'd probably lose the block if you ever found one.

My understanding is that 1024 is a larger fraction of 39.5B to be solved. Competition is not against the other miners, but against... Well... Probability. There's no competition actually, only probability. A hash of difficulty 1 has no chance of solving a block of difficulty 39B. A hash of diff 39B or more can "solve" it. Your miner submits hashes to a pool just to prove to the pool that your miner is working. Otherwise, you shouldn't have to submit shares below the current network difficulty. When you solo mine (not in a pool), you don't need to submit hashes below the difficulty. Pool diff and network diff are two different things about the same concept of the "target". It actually took me some time to understand this! :-)

I think ck is a female. Ck stands for Cynthia King (no relation to Martin Luther King)
1. No. 2. How is that relevant? he quoted my post in which I refer to his server runs this pool. Frankly I don't know if he is just kidding.

would use same money to longer mining time slower hash I would hold onto the 2 BTC. The approximate odds of finding a block in 5 hours would calculate to: ~320,000 Th/s bitcoin network 700 Th/s your hashrate 30 blocks (1 block per 10 min, 30 blocks in 5 hrs) 320,000 / 700: 1 in ~457 per block 457 / 30: 1 in ~15 for 5 hours timeframe. Do you feel lucky? Can you afford to lose those coins?

Take Care, Sam The only competition in mining is an orphan race. Otherwise it doesn't matter when anyone finds a block coz you simply switch your work item to a new one and continue searching. This switch also happens every 30 seconds and every time anyone on the planet finds a block. Every block found is "randomly unaffected" by every other block found, other than a work switch. So for example, if someone finds a block here, the next person who finds a block here could find it 1 second later, or 100 days later - they are "randomly independent" of each other. There is no competition, there is no spoon ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

So, Kano is absolutely right in the sense that finding one of these 2016 blocks is independent of what else has been found. The first 2016 finishers all win. And in about 2 weeks, the race ends and a new 2016 block race starts, which might be a little harder or easier than the last. This all happens transparent to the miner who is happily working on a new math problem provided by the server every so often
