The Blocks Factory - Multicoin pool

[lucazane]

Now my payouts dropped to half of what they were reported as.  I may be back if you can fix your pool.  This loses a lot of trust though.

You can see on the transaction page that your unpaid share has been paid after, on the blocks mined after you left.

My payouts went from ~11 pxc per block to 4.5 without a drop in my hashrate or a rise in the pools hashrate or accepted shares.  I'm guessing this was around the time you changed the N shares, and it may have reset the total shares? Im back on, we'll see how the lower N value goes.  May I inquire on what you set the value as?

i set the value at 5000 it was 20000 before


In theory, you should see you Payout going from 0 to expected hashrate slowly when you join a pool who pay in pplns

No blocks in 30 minutes? Is the pool really having that much bad luck or is there something else going on?

[docjunior]

Close to one hour now, and no new blocks??

[weav]

This smells fishy.

Over those suspect 2 hours at the average hashrate of 50MH/s or 1 block every 5 minutes we should have gotten: 2 * (60/5) = 24 blocks.

Yet we only got 8 blocks. (see http://pxc.theblocksfactory.com/blocksAuth)

Block generation is a Poisson process and the probability of finding no more than 8 blocks when 24 blocks are expected is:



where F is the cumulative distribution function of the Poisson distribution.

Not exactly likely.

UPDATE: Seems like the blockrate has been suddenly back up to normal while I was editing this post, not sure what to make of it. I first deleted the post after seeing it's back but now decided to post still because of the statistical peculiarity, let's keep an eye on it.

[ronaldinho_07]

more miners come in your pool now so it's stable 

[weav]

Alright, this is getting very suspicious.

Again, consider the last 2 hours: http://pxc.theblocksfactory.com/blocksAuth

Within this timeframe we have been at an average hashrate of 70MH/s per second which (at 1 block every 3 minutes, as specified in the pool statistic itself) should have produced 2 * (60/3) = 40 blocks.

Yet the pool apparently found only 12 blocks, namely:  #42879; #42793; #42758; #42736; #42678; #42673; #42653; #42648; #42626; #42614; #42609; #42600

The probability of finding no more than 12 blocks when 40 blocks are expected is:



where F is the cumulative distribution function of the Poisson distribution.

No idea what exactly is causing this (scam, technical issue, or some kind of attack) but this is far far below all reasonable or common significance levels in statistical tests, meaning the chance of this happening simply by chance is so incredibly small that believing it would be exceptionally stupid.

Also rewards are completely missing for certain blocks.

Well that's it, I'm out for good.

EDIT: And another one which took 31 minutes while I was typing this out: #42966. Yeah right.

Big problems are on this pool

We missed a lot of block today.
Unfortunately I should out!

We actually missed 5 blocks in the last 24h ( 5 orphans) but it's normal when hashrate jump from 80 Mh/s to 700 Mh/s without diff ajustment

[lucazane]

extra block reward increased : 1 pxc

pplns is now fine !

[UniversalTrek]

Keep it up

[lucazane]

Keep it up

I will try

We need hashrate !

[lucazane]

come on miner we need to mine PXC to become RICH

[lucazane]

extra block reward is now 2 PXC come on !

[lucazane]

Come, we are in chance :



The 2 pxc extra reward is still effective
