Alright, this is getting very suspicious.
Again, consider the last 2 hours:
http://pxc.theblocksfactory.com/blocksAuthWithin 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.
