Kano-

On one of my pools or miners i used to track highest difficulty share mined per second or something and chart it on a graph.

I know itd be pointless, but maybe a fun way to "pass the time" to show a graph like that. Plus then we could all get angry about how close we get to solving a block.

Just an idea I had anyway.

If the data was available thru an api I could throw something together.
I don't track or store the 'current' 'best share' on purpose Smiley
If you submit 1000 valid shares, and your work difficulty is X, every one o"f those shares is worth X, no matter how high the difficulty is.
As long as they are X or more, they are worth X.
This is how all reasonable and fair payout systems work.

Any other valuation of shares adds yet more variance to your rewards and allows people to take advantage of that.

Many people look at the "best share" value and assume it means something, when in fact it means nothing at all ... unless it's a block.

You miner knows it's "best share" if you are curious to see what it is.

However, I do store every share above a limit for my regular statistical analysis, but no I wont be showing graphs of that.

to simplify "close only counts in horseshoes and hand grenades " Cheesy

This I know. But its still fun to watch. I like to think my miners are trying really hard and give an A for effort.

Is anyone running with the new 821's yet? Any issues? They seem a little pricey but thinking about growing a little.

They work flawlessly.  Just getting used to them being combined as one miner, since I'm not buying another Raspberry Pi just for this.  But really stable and run about 11.5 T/H or so.   

Mine has been rock solid.

what is the recommended power off procedure for the AvalonMiners? I had to recently move some and I just pulled the Ethernet, wait until it spooled down and unplugged them.

Also Canaan released new firmware and controller software today for the 821.

Anyone tested it yet?. I don't want to be the first canary in the coal mine, so to speak.

Have you given any thought to stratum with SSL to prevent MitM attacks? I noticed some altcoin pools enabling it... I guess this question would also apply to cgminer.

Noticed some altcoin pools doing stratum with SSL in an attempt to prevent man in the middle attacks, etc. Has any thought been given to doing the same for kano.is? Presumably, cgminer and forks would need to be updated as well...

Back to 60PH! Let's hope it sticks this time.

EDIT: ...Aaaaannndd, it's gone.

You can't count on the Canaan numbers being reliable for long periods of time, those are testers for the most part and they drop off within a few days.   It's when people like cryptostar and sidewinder show up, that we need to be cheering!

HUZZAH FOR THE BARKEEP!

MINE ON WITH KANO-SAN!

Yes Canaan numbers go up and down.

However, I've certainly no complaint to make about that - they consistently point a lot of hash rate at the pool!

You CAN count on them reliably pointing a lot of hash rate at the pool for a long period of time!
Just not exactly how much Smiley

I think their miners come default to this pool too, so if someone just plugs in to test without checking the config they'll hit here.

I would hate to be using a miner that was ripped off of claymore's. Competition is good, but not at this cost.
It's not the competion if we steal something and sell it for less.

I'm following this whole saga with great curiosity but, to be fair this is exactly how a lot of China has operated for decades...

- All else being equal, on a long enough time scale, the ONLY thing that makes one pool pay more than others is a lower pool fee.
...
Yes, but the "All else being equal" also includes pool hash rate to some extent.
If the pool gets too small - as I've been trying to avoid over the last couple of months and will hopefully have some more hash rate here soon again - the diff changes also can affect your reward dramatically.

This is why I mention on occasion "as long as we are expected to find a number of blocks each diff change"
The issue is that if you're mining for multiple diff changes per block, then your reward loses around half the diff change from start to finish.

A simple example is that since 13-Jan difficulty has increased by 55.73% (yeah that's a scary number)
So if you were mining from say 10-Jan to now and then found a block, you'd actually lose over 25% of your expected reward!
All your shares from then to now have different PPS values, but your reward is based on 'now', the much worse PPS value.

This also affects us here to a lesser extent due to the fact we don't expect to find many blocks per diff change.
Thus why I'm trying to get that hash rate back up again.

Small pools like to pretend this doesn't happen Smiley

So basically this is a bad side effect of the N in PPLNS stretching over difficulty changes?

If yer looking to win the contest he has said he learns best with a visual representation.

I don't really care much about the contest. But I did make some rudimentary drawings a page or two back.

I just cant imagine making it any easier than what I have previously written/drawn. Mining isn't a hobby for children. Nor for idiots trying to get rich quick without taking more than 10 seconds to understand what they're doing.

...anyway

Come on green blocks!

Well something is going on at my house. All of my miners quit showing up at the pool at the same time. Im stuck here at work so I cant even check to see whats going on. Now im going to lose a day of mining.  Angry. I must have either lost internet or power. This sucks.
you should look into "ausome miner" properly configured u can manage your miners from anywhere. wont help if yer house burned down or the wife ran off with your miners.

Lol if my wife runs off with anything it won’t be my miners. In fact those would probably the only thing left. I found out our internet is out. There is a line down and the service provider is trying to get it back up. Guess I have to wait.

East Coast? we're getting crazy winds today...

k lets give this padrinogtr  thing another try Cheesy. let start by taking all the luck and unnecessary stuff out of the equation.  so lets start by saying there are 5 pools in the world mining the blockchain. it spits out 1 block per day.
day 1 pool 1 gets block day 2 pool 2 on down the line till pool 5 we will call that our pool Cheesy. most (the other 4 pool) using the similar pay system payout WHEN they get a block with the blocks reward they do this buy looking at how much each member worked during the day and turning that into a % that compares with the rest of the workers in the pool. they are payed a % of the block = to their %. in the kano pool its the same accept we look back 5 days instead of 1 to find each workers % again u get the % according to your %. after 5 days u will get the same block payout as all the other pools (accept they have higher fees generally which makes the block smaller). the difference is it takes a whole 5 days instead of 1 to get your full % the up side if u quit or are down for 5 days u are still getting though a diminishing return as the days go by.
  so bottom line kano pool pays bests over the long term due to lower fees. this system is good because if u have break downs or gaps they wont be noticed as much but the real purpose is to stop those who pool hop (try to only work for the pool that is paying on a specific day)  there goal being to get payed everyday instead of once per five days. now there is no point in pool hoppers showing up here because they wont be able to take there money and run to the next pool cause we dont pay them jst for punching in on payday.
  howd i do padrinogtr Cheesy i dont think i qualify for the contest anyway but id like to know if i helped though i haven't seen yer name here in awhile:D.

No offense, but I think you're actually adding unnecessary stuff to the equation.

Also, your premises are flawed

- # of pools mining and number of miners mining has no impact on anything. Only global hashrate and network difficulty (which is adjusted approximately every 2 weeks based on global hashrate) make any difference.

- in your example, those are still PPLNS payout methods if all blocks take 1 day. If that's not what you had in mind, then what you're describing is maybe "PPLND" or  proportional method with rounds equal to 1 day time frame.

- All else being equal, on a long enough time scale, the ONLY thing that makes one pool pay more than others is a lower pool fee.

- re: pool hopping, you need to read organofcorti's write up here: https://bitcointalk.org/index.php?topic=104664.msg1146110#msg1146110 and here: https://bitcoil.co.il/pool_analysis.pdf

I'm not even sure what sort of questions you're asking anymore. Or what sort of explanation you're looking for.

Been away for a bit, happy to see we have some more blocks!  Thanks canaan x 2 and biffa!

I was crunching some numbers, and I joined this pool after we found block 504409 (our block # 2202).   

Looking at the 44 days I have been mining in the pool, I have been a party to 7 blocks, with a cumulative difficulty of 1,453.543%, or roughly 207.649% per block.

If I am correct, statistically speaking, we were expecting to find about 14 blocks in that same time frame, but due to bad luck we found half of that.

So my question is, is that correct?  Am I reading and understanding the numbers properly?   

Thanks in advance!




Back of envelope says that's probably correct. Looking at the blocks, 2202 was mid January. Overall January had over 100% luck, but mostly due to very good luck in early January. Late January had less than 100% luck average and all of February was pretty bad... 44% luck. So yeah I could buy your numbers.

Hi,
I am new to the pool.  Smiley
I have joined few days back. I am cranking around 37Th/s

So just wanted to check how exactly are shifts and rewards calculated.

Here are my shifts on the last block.
https://www.dropbox.com/s/p1eb92ekp0xha2v/shifts.JPG?dl=0

And here is the reward.
https://www.dropbox.com/s/sf8e3wv1nnez7bl/reward.JPG?dl=0

Of course I dindt work all shifts for the block but reward looks so tiny for 3 days of cranking with approx 37Th/s.  Smiley

Thanks.

My take on a post from Kano a long while back:

The 5Nd "ramp" means it takes that long to reward your shares.  It's not a punishment and The ramp isn't missing rewards, it's delaying them to reduce variance.  Each share is rewarded in all the blocks found in the 5Nd after the share.  That's simply how it reduces variance. Each share's reward is averaged out over the 5Nd after it.

How do the PPLNS payments work?

The 5Nd means the pool rewards 5 times the expected number of shares each time a block is found.  So each share will be paid approximately 1/5 of it's expected value in each block it gets a reward, but each share is also expected, on average, to be rewarded 5 times in blocks found after the share is submitted to the pool.

So, on the 1st block the pool hits when you start on Kano you get rewarded 1/5 of the value of the shares you submitted for that block.  On the 2nd block the pool hits you get 1/5 of the value of the shares you submitted for the 2nd block plus 1/5 of the value of the shares you submitted for the 1st block.  On the 3rd block the pool hits you get 1/5 of the value of the shares you submitted for the 3rd block plus 1/5 of the value of the shares you submitted for the 2nd block plus 1/5 of the value of the shares you submitted for the 1st block and on and on like that until all of the value of the shares are paid.  That's also how you would continue to get payouts for the 5Nd ramp down period after you leave this pool.

This is a simplistic view of 5Nd because it is also affected by luck.  If pool luck was always 100% then each share is expected to be rewarded 5 times.
If pool luck is better than 100%, then the average share reward will be better than 5 times. (Love it when it hits 10-12 times!)
If pool luck is worse than 100%, then the average share reward will be less than 5 times.

The 5Nd really helps you out if your miners go down for a couple of hours or are down for a day.  You would continue to be rewarded if the pool hit a block while you were down.  I've seen pools where you would get nothing out of a block if you were down for just an hour or so when the block was hit. Grin

The 5Nd windows isn't affected by luck. Whats affected by luck is how many solved blocks fall into that window.

@Vene if you look back a page or two I made some really simple pictures. But to be as simple as possible, when this block was found, it looked back at roughly 15 days worth of stats to determine payouts. Since you've only been mining for 3 days, your payout was smaller.

A really rough calculation would be (37/49091)*(3/15). This would be (your hash rate / pool hash rate) * (how long you've been mining here / current length of 5Nd "ramp")

But this calculation isn't exact because your hash rate and pool hash rate both fluctuate, how long you've been mining cannot be more than the length of the 5Nd "ramp" and the ramp itself changes length in terms of days when network difficulty changes.

Also important to note that the bitcoin you may be thinking of as "missing" are really just delayed. If you stop mining now, and we hit 3 blocks tomorrow, you'll still get paid for them since there is also a "ramp down".
