Who is the pool operator of Bitcoin P2Pool?! It have a pool operator?!

[ThiagoCMC]

Please, enlighten my doubt...

Another question, the P2Pool can have merged mining with Namecoin?

There is no operator.  There is a primary developer but the whole point of P2pool is that there is no operator.  The "pool" operates in a distributed fashion similar to how bitcoin itself works.

The "pool" generates a share chain based on protocol rules.  When a client finds a share it submits it to the chain.

Simplistic version:
Your p2pool detects other p2pool nodes similar how Bitcoin nodes detect the rest of the network.
You query the share chain for all shares completed in prior 24 hours.
Based on protocol rules hardcoded in the client and the list of shares in prior 24 hours your node generates a block header giving each miner their "fair share" (similar to how a traditional PPLNS pool distributes rewards).
When you find a share you submit it to the share chain.  As each client is updated they updated their block header shifting rewards to the most recent 24 hours.
When you find a block the rewards split is already hardcoded into the block header (coinbase transaction)


If you are asking if the "luke attack" could be done w/ p2pool the answer is no.  That is the entire point of it.  Each miner is "smart" it.  It computes its own block header and thus can't be "duped" by a pool operator having it do malicious work.

That is all I need to know.

I'll work to make P2Pool the most used pool but, what will happen if P2Pool have +51% of the power?!

Then rest easy.  IF p2pool had 51% power it would be no more of a danger then is a bunch of solo miners combined had 51% power.


The added bonus is that is p2pool had 51% power it would make Bitcoin even safer as it would ensure no other combination of pools could have 51% power.

So, the P2Pool is the pool of the future of Bitcoin.

I'll work to make it even more easier to use.

And about merged mining... I care too much about Namecoim.

It can be done with P2Pool (Bitcoin / Namecoin)?

Thank you!!

As it should be.

Namecoin merged mining with p2pool is solo right now. It works fine but its not pooled. So you get the benefit of pooled earnings for the bitcoin you generate but not the namecoin.

Great the project could use more dedicated developers/promoters.

One thing to keep in mind is that variance is higher w/ p2pool especially for small miners so it may no be ideal for everyone.  P2pool needs to ensure the network (as a whole) doesn't produce shares too quickly.  If two shares are produced based on prior sharechain share then there is a network split  (much like Bitcoin).

To avoid that the p2pool network raises share difficulty based on network hashing power to keep average share time at 10 seconds.  If p2pool got very large this would result in a very difficulty share.  Your avg time between shares in sec = (10 * p2pool hashrate)/(your hashrate)  So if you make up 1% of the p2pool shares will take about 1000 seconds or ~ 17 minutes.  If p2pool every got very large this could be partially mitigated by an improved protocol which grouped miners into smaller "sub pools".

And about merged mining... I care too much about Namecoim.  It can be done with P2Pool (Bitcoin / Namecoin)?

Currently p2pool doesn't support merged mining but there is no technical reason it can't.  Technically one could even make it option (user makes a choice to turn merged mining on or off).

Thats not true, --merged-url   and I've mined 3 blocks with it.

Please tell me how to merge mine nmc. solo or not..

WTF?

start your own thread and try to use google or search the forum...

Wtf WTF? He asked about merged mining and I have the same questions. That post doesn't help, I already tried it. Its for linux plus it makes no sense in some areas. It looks like it is mining LTC seperately.

Huge WTF!! 

That post/guide makes all sense and it is perfect.

I just need to update the donations section of the guide.

Plus, the context of this thread is about P2Pool "operators"... This is starting going to off-topic...

Cheers!

Welcome in P2Pool, the only safe and decentralized pool. All the advantages of solo mining with all the advantages of pool mining.

Thank you Gabi
