Kano, thoughts on this on block withholding?  http://organofcorti.blogspot.com/2016/02/detecting-unintentional-block.html

Heh he picked the same number I said on the slush thread - 10 blocks.
Yes the pool already has information about that ...

That is some interesting stuff.  Why would someone do that here?  Would it be to benefit from faster block change notifications? Harm the reputation of the pool?

I'm pretty sure I saw the word "unintentional" in there somewhere.

That's to do with possible detection of a specific "unintentional" problem.
However, if someone has $100k (or more) worth of "unintentional" miners, do you expect people would just throw them away if there was no real fix for them ... ... ...

In the post, "Intentional block withholding" just means the max sized share changes to match difficulty, which can only be done on purpose. Any other problems that causes valid blocks to not be returned to the pool -- even a network problem -- is "unintentional".

I meant "intentional" as an intentional attack against a pool (which could be extremely hard to detect) rather than someone with known faulty equipment that they can't repair wanting to mine and not caring who they affected.

So yes, Kano is right -- people can be intentionally acting like dicks and still be "unintentionally" block withholding. As soon as someone comes up with better terminology to describe the differences, I'll be the first to use it.

Not picking on you - it's something I've read lots of times.

But ... ok ... I do need to add something else also for the 32-bit miner failure ... ok that hits the top of the todo list ... ... once I finish this I'm working on.

I envisioned this as an automated screening test that would be applied to all user accounts, and wouldn't have to be tied to just the known modes of failure. Let me know if anything in the post is unclear and I'll lend a hand.

To my knowledge no one has automated a similar test yet but it's pretty simple. Keeping track of the difficulty, user account and pool difficulty of every submitted share might be a PITA though.

Yeah no trouble understanding what you did - as I mentioned in your thread, it's obvious ... but yeah the thought never even crossed my mind
That's why I posted in here twice about it.
First time was ... yeah I keep basic block/diff stats per user.
Second time was ... OH! That's what he means ... OK that's a good idea!

My solution is very simple, log all shares individually above a certain difficulty.
I already store a LARGE amount of data in the permanent database and in ram ... a few (10s 100s whatever) thousand more records is no big deal and ckpool already has the numbers in each share record it sends to ckdb.

I do already have simple full block/submit statistics for miners that even shows on the Acclaim web page ... if you're me, but for none else

Hi i've mined 4 or 5 days without btc adress set  how can i withdraw my BTC

-Login
-Account tab -> Settings

"To change your payout address, enter a new address and your password
BTC Address:"

-Input BTC address.

I've input the adress how can i withdraw them all rewards?

I have a lot of rewards that were not sent and i want to withdraw them because are my BTC

I think Kano does this manually whenever it happens, as long as it is over the dust threshold  ...send him a PM and he will take care of you...

Ok it is over

Check your PM txn sent

Sweet !

I can't wait to get my S5 and add it to my current miners on the pool ! (2xS3+, 6 compac Gekkoscience sticks, 5xU3)

Part of the internet lost contact with the pool again (myself included) - was an asia-pacific issue again since DE was ok.
Outage was around 2 minutes this time at 11:33 UTC
We dropped from 23PH down to 20PH so I guess that means about 3PH were connected through whatever part of the internet lost connection with the pool data centre.
All is OK again.

hello guys

one question, i'd like to set the stratum difficulty manually on my miners to 20 shares per minute as suggested in https://bitcointalk.org/index.php?topic=274023.0

i did this on my Avalon6 controller without problems using the "--suggest-diff" command on the cgminer "more options" field available in the Avalon6 controller interface.

however i got a few Antminer s7, s4 and s5 that do not offer any field to enter any extra cgminer commands, anybody know how do i set the stratum difficulty manually on Antminers?

thanks in advance for any information

You can set it directly on the pool for each worker, under "Worker-> Management"

Hello,
I do not think there is interest for you  to increase the pace, unless you have a very high hashrate.
If everyone does that, it will increase the traffic kano servers and it can have more disadvantages than advantages.

I think the best thing is to let kano team fix the steady rhythm. He must surely calculate the best compromise between the possibility of its servers, your hash rate and latency.

It is interesting to reduce the rate if your internet connection is slow or if you have to pay the amount of data.

Double whammy!!!!!

twin turbo block )))

[cavaliersrus]

wow we got 2 blocks within a min of each other what a way to start the day today

[stonebone]

New best with 0.225 Diff%

Old record was block 386503 with 0.226 Diff%

 

[kipper01]

I wonder how many other pools were still looking for the 1st block when we found the 2nd of the back to back blocks.

-ck (of course) wrote the code in ckpool that sets your diff
The target is 18 SPM

Yeah I meant it the other way around.
You, the stats pro , used 10x and I guessed right about (the same) appropriate value when I commented in that thread.

Sigh, lost DE there for less than a minute (13:48:38 UTC)
DE itself didn't lose connection with the main pool, just almost anyone connected to DE lost connection and may have failed over.
Linode again
All's ok again now.

why not create a different worker for each miner?

wouldn't that allow you to see which ones might be having an issue/offline. which would also let your use the auto-diff from the pool instead of using the manual diff.

i like having separate workers for each miner as it lets me see/track the changes in shares/hash rate of each as i fine tune/tweak each miners frequency. Slowly tweaking the frequency up/down to find the optimal hash/stability.
ie one of my s7s only likes stock frequency the other likes more power and still wanting more.

it's not possible....Avalon miners use a centralized controller and all the miners are connected to the same controller via proprietary cables, you can set only a single worker in each controller. I have 1 controller with 11 Avalon 6 Miners, so it's one 39 TH worker for all my Avalon 6 machines.

I have 5 avalon6's I would like to try the  command  could you show exactly how to write it?
