Ethereum mining wiki lacks details. Best I could find was on github:

(U_n + 8 - B_n) * R / 8

Where:

R = 5 (ether)

But can someone explain what do U_n and B_n represent?

Why? Got a block reward from ethpool that was only ~3 eth I'm assuming because it contained 2 uncles.

## Comments

2,249✭✭✭✭21✭U_n is the uncle number.

B_n is the block number.

R is the reward of 5 ETH.

if B_n = 1337 and R = 5

then U_0 = (1336 + 8 - 1337) * 5 / 8 == 4.375

and U_1 = (1335 + 8 - 1337) * 5 / 8 == 3.750

and so on

21✭15✭`(1667 / (35703 + 1667)) * 100 = 4.46%`

Which means there's a decent amount of other miners on that pool being rewarded for uncle blocks and I'd like to verify the payouts are correct.

@5chdn thanks for the info! So let's try an example.

ethpool rewarded 3.09375 to 0xdeb5515fb01bf24d2f1dfb505c7e7f21798696cc for block 1071819. There were two uncles associated with the block: 1071816 and 1071817. So let's assume ethpool was really paying out a reward for the block's 2nd uncle, 1071817. So:

`(1071817 + 8 - 1071819) * 5 / 8 == 3.75`

So far so good. Now let's deduct ethpool's 1% fee:

`3.75 - (3.75 * .01) = 3.7125`

Still nowhere near the 3.09375 reward. So is ethpool skimming or did I miss something?

15✭`(1071816 + 8 - 1071819) * 5 / 8 == 3.125`

Then deduct the 1% fee: So looks like it's all good. Thanks again for the help

445✭✭✭71✭Whereas 1071817 was mined by coinmine.PL (given your links).

In that case :

`(1071816 + 8 - 1071819) * 5 / 8 == 3.125`

`3.125*0.99 == 3.09375`

So this seems correct to me

Edit : Already two answers, guess i'm a bit slow
