Title: Is deepbit payouts fair? [Solved]
Post by: DavinciJ15 on July 22, 2011, 04:07:43 PM
[NOTE I figured it out it's a floating point error as I have the same problem in my pool]
So I decided to do some math to see if deepbit was paying us fairly and maybe my math is off.

Deepbit charges 3% right?

OK so I checked transaction...
http://blockexplorer.com/block/00000000000006a25eb47b2c28151bebab4c1ee1ac9a060df748075f0b14fe55

Payment for Block
50.02197243 BTC

Total shares are
3140439

My Shares where
156

Payout
0.00240922 BTC

Sounds good right well.

3% of 50.02197243 = 1.5006591729
Giving us a total of 48.5213132571 to share
Now divide that by the total shares of 3140439 =
1.5450487418192169948214246479553e-5
or
0.000015450487418192169948214246479553
Now multiply that by my work of 156 shares =
0.00241027 BTC

Now I know what your thinking that's like off by 0.00000095 Really dude!?
Keep in mind I don't care about that small of amount but if you do it to enough people it's not right.
Also my math may be off so I am not accusing him of anything because people can get paid per share of
0.00002661294865101 BTC
so on that block I could have been paid more on a per share basis.

So just help me figure this out.

Cheers

Davinci

The pool operators tend to keep the transaction fees - miners divide the 50BTC after fees. Use 50 as your starting point and your payout is exactly what it should be.

Deepbit pays transactions fees for distributing earnings.  Could that be the source of discrepancy, or is that price already factored into the 3% fee?

Edit: Probably factored into the 3%.  Talldude's answer accounts for the discrepancy.

Some people are also paying 10% fee for PPS.

Talldude's post -> 50 BTC
-> 0.00001592134093354 BTC / share
-> 0.00248372918563296 BTC for OP
-> 0.00240921731006398 BTC when 3% charges paid

We're saved

My experience with deepbit is probably slush paid a little bit more, if with the same luck (and yeah, I already took into account the difference in commissions). Could be related to the algorithm as I trust both pools are honest.
