Could someone please prove my following maths wrong:
hash_rate = (blocks_found/expected_blocks*difficulty * 2^24 / 30)
I looked at the block window from block 456520 onwards (approx 2013-12-14 20:10:18 GMT)
Lets look at a 5 minute window, which should get us 10 blocks.
Depending if we start this window at 20:10:00 or 20:10:18 we get 10 or 11 blocks "solved" in that time, so lets take the middle and take a factor of 1.05
So we have:
hash_rate = 1.05 * 6411.26760900 * 16777216 / 30
hash_rate =~ 3764712752 =~ 3,76 GH/s
So we have approximatly a network hashrate of 3,67 GHashes per second.
http://qrk.coinmine.pl/ showed at that time an approximate pool hashrate of 3,8 GH/s.
So either my maths are totaly wrong, the pools hahsrate display is totaly wrong, or houston, we have a very big problem...
pools hashrates are notorious for being wrong.
So what du you think the real hashrate of that pool is?
3 GHash, 2,5 GHash?
EDIT:
Just looked at the generation TX of last 100 Blocks:
From 86 of them the destination address was the same, which i assume is the pools address.
This means, although this is only a very rough estimations:
86% of the networks hashing power lies by this pool, and here we are: housten, we have a very big problem...
EDIT2:
Looking at the stats prooves this:

EDIT3:
And just to be clear:
i personally have no reason to distrust the pool operator, but thats a thing that needs to be fixed ASAP or bter38 will never come, and maybe otehr trading platforms will suspend Quark wich would definatly be a pity.
talk to Feeleep he is a member here and runs the pools.
