Not in the windows of the blocks? I'm mining now for around 30h, the pool found 15 Blocks in that time frame and I only got 4 payouts. (Mining LTC at ~100kH/s with two machines; scrypt.)

# Why is my p2pool share not payed out?

(Asked by: username_0 on 2013-08-20)

I'm mining Litecoins in the [q30.qhor.net](http://q30.qhor.net:9327/) P2Pool node at a current rate of around 75 kH/s.

I've been reading that decentralized p2pool mining differs a bit from centralized mining pools, e.g. that you only get paid out when a block is solved successfully.

Now, I'm mining for about 8h now in this p2pool and during that time 3 blocks were solved:

```
Block   Time                            Luck
409925  Tue, 20 Aug 2013 17:09:16 GMT   155.4%
409848  Tue, 20 Aug 2013 14:02:12 GMT   95.1%
409784  Tue, 20 Aug 2013 12:07:41 GMT   165.1%

```

That means, some payouts occured during that time. I checked some of the other addresses, they really got instant payouts. But I didn't.

```

But I did not get any payout, yet. Why?

The PPLNS payment system is not to be considered as the best for slow hash rate miners. To get payouts, you need to:

3. check if your p2pool server avoids dust payments, meaning that very small payments are hold back until a certain threshold is reached, e.g. > 0.01 ŁTC.

I'm mining at around 100kH/s (867.9 block difficulty) and only recieving payments once every four/five blocks. This is a bit discouraging but in total I'm getting higher payouts than mining in *normal* pools.

By the way, the minimum recommended hashrate for p2pool-miners is [590 kHash/s](http://ltc.noshit.pl/p2pool).

I do not know if there is any other problem that could prevent you from receiving payment.
