Thanks for the answers!
If i understand it correctly a real bitcoin block that was found by a p2pool miner cant be stolen by him because this block already includes all the reward transactions to those miners that mined on that block. So a miner has to decide upfront if he wants to mine p2pool or solo. Deciding to change this wont work after a block was found.
That means the reward 25
BTC + fees is created and in the same time these newly mined bitcoins are broken apart? I didnt think this can work because the actual block only brought this coins into existence but at the same time is splitting it. But it seems to work then.
What i meant regarding the reward. The split of the reward among all miners means that the newly mined block is not having the newest data. Up to the last 10 seconds of mining of others can be lost because not already included. 10 seconds are a good choice then to minimize this i think.
I tried to install the groupcoin wallet because at the moment i mine at bitparking.com and need an address. I dont get how its done. And there is no exchange for groupcoins to get an address from there. So maybe in the p2pool community there is a way to circumvent this by someone providing an address where i could send my rewards to and later sell it at Open Transaction? So that not everyone has to create his own wallet? Is there such thing already?
I have read its possible to mine litecoins too. Would it be possible to hire a coder that creates me a script so that i could mine any other 256 Coin with p2pool too? I have read i even could merge mine this way. Is this possible in p2pool?
The amount of lost shares in p2pool are normal. And every p2pool miner has the same. So its fair among the p2pool users.
Theory: But that means that a certain amount of hashpower is lost compared to solo mining. The shares maybe were good but they are lost and so is the amount of time invested in them.
Solution?: Am i right that this is no disadvantage to solo mining because the real bitcoin block that is found in p2pool is directly put into the network via solomining? So the lost shares does not affect in the end because for the real found block those lost shares dont exist. Correct? Then p2pool would be even better than normal pools because they have to receive the found share first and from there propagate it.
Sorry for the many questions...
