Welp, my plan took a dive. I'm gonna tweak my rules a bit and give it one last shot before I call it off because it's going to get lost in the pages anyway. I think the changes will open it up to a lot more miners who may have a good answer (including NEW miners).

BTC 50 TH/s giveaway !!!! BTC
I want to see how well the small miners understand this and can explain it on a level where YOU(and others, including myself) fully understand it. I want that light bulb to go off and have ZERO doubt about how we are getting paid for our shares and I will donate 50 TH/s for a period of 5 days to a lucky winner.
My rules:
1- You have to have been mining on Kano's Pool with a hash rate between 1 and 20 TH/s
2- The rewarded hash has to be pointed at Kano's pool. (to be confirmed by Kano)
3- You have to submit your answer in response to this quote and give 2 working examples including the payouts calculated.
4- padrinogtr will have to be able to explain his new understanding with his own example in response to the submitted answer and have the answer's accuracy verified by Kano.
5- New miners to the pool are welcome, though you will have had to have been here for at least the last block (this will help ramp your 5Nd up much sooner!!)
The 5 day 50 TH/s award will start as soon as I am able to see confirmation and have access to my controllers. I will of course need a worker name.
I understand this is dependent on some cooperation from others, but hey it's 50 TH/s on the line and I'm currently only running about 70 TH/s, so it's a big deal to me.
5 days - 50 TH/s .... don't let us down padrinogtr!!!!!! There was talk of others donating some hash too. If their offer is still good, that hash will be separate and in addition to the 50 TH/s I am donating.
*Of course, this is for fun and in the event of a hash rate failure, I will not be obligated to make it up as noted in prior promotions. I hope I'm not leaving out any details. I will stay active with the announcements as well as open to hearing some feedback or details that should be edited.
Thanks everyone and MINE ON!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You set rules and mentioned an answer but didn't mention a question, so im gonna assume the answer is 42.
Oops! I copied and edited the original which was following a quote. I can't fix it at this point in time, I'll have to come back to that.
The competition is basically to explain the 5Nd in the simplest form. There have been many explanations, but it is still somewhat of a mystery to many. It was in response to a certain member (padrinogtr) not being able to get it no matter what. He has to understand the answer in a way that he can explain it to others. I'm assuming he's a he...
Well the simplest explanation of 5Nd is that its 5*Nd where Nd currently = 3,007,383,866,429.7 and so 5Nd = 15,036,919,332,148.5
But if you mean the whole of PPLNS, its basically a moving average window.
The foundations you have to get first are:
- mining is done in shares.
- shares have difficulty
- a single, 100-difficulty share is (for PoW purposes) roughly equal to 100, 1-difficulty shares.
- Nd is the expected amount of work to be done in order to find a block (but this is an expected statistical average, meaning IN GENERAL and AT THIS POINT IN TIME, if you do 3,007,383,866,429.7 shares of work, you will solve block). When we talk about these % that get higher, Nd (or 1Nd, same thing) = 100%
So on kano.is when a block is solved, it looks at work done by all members in a window the size of 5Nd numbers of shares backwards in time, and splits the rewards of the newly solved block proportionally among the work done in that window (after skimming the pool fee of 0.9% off the top).
Here are some pictures
Scenario A:
In this scenario, 1Nd = 700 shares. When block AA is solved, the pool looks back 5Nd worth of shares, calculates the total shares, then divides the block rewards accordingly.
Total shares = 3500 ... Miner 1 = 500 ... Miner 2 = 1000 ... Miner 3 = 2000
Miner 1 = 14.28% ... Miner 2 = 28.57% ... Miner 3 = 57.14%
So if block reward is, say, 13 BTC, then
Miner 1 gets 1.83 BTC ... Miner 2 gets 3.68 BTC ... Miner 3 gets 7.36 BTC ... pool gets 0.117 BTC
-----
Scenario B
In this scenario, when block Z is solved, the pool looks back 5Nd worth of shares (as above), calculates the total shares, then divides the block rewards accordingly.
Total shares = 3500 ... Miner 1 = 1775 ... Miner 2 = 900 ... Miner 3 = 825
So if block reward is 13 BTC again
Miner 1 gets 6.53 BTC ... Miner 2 gets 3.31 BTC ... Miner 3 gets 3.03 BTC ... pool gets 0.117 BTC
-----
Note that these scenarios are simplified and the 5Nd window doesn't always end on the same time a block is found. I just did that to make things simple. I believe Kano does the 5Nd calculation by the shifts, which is explained on the help page
https://www.kano.is/index.php?k=payout. Roughly, though, shifts are every 50 min or less and are defined by work changes, block solves, or pool restarts. Specifically though, shifts are NOT defined by amount of work done.
So realistically, there should be even smaller verticals inside each block-solve worth of work that are the shifts. It's just that in my examples, the 5Nd worth of work done in shifts would fit nicely into the block-solves worth of work.
Ninja edit2: someone please correct me if any of the above is wrong, but I'm 99% sure I've explained accurately. Whether it was simple enough... well... who knows.
