[1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool

[Polyatomic]

In a desperate attempt for answers, you could ask in #p2pool on Freenode.
Though the channel appears to be a remnant of a great era now.

Who knows what we are still verifying ?

Code:

2015-11-01 04:40:47.880774  Pool: 1311TH/s Stale rate: 20.0% Expected time to block: 2.4 days
17402 shares in chain (17406 verified/17406 total)

Khm..and this is decreasing

Code:

2015-11-01 04:58:25.163393 P2Pool: 17328 shares in chain (17332 verified/17332 total)

I'm not sure I fully understand you question but a maximum of the last 8,640 shares are paid (often less) when a block is found...

Thank you for reply.  Actually I am not expert and I thought that we should find block before (or when) all shares in chain will be verified and found.   For example 2 days ago there was this count in p2pool log file

Code:

2015-10-29 21:21:25.788644 P2Pool: 17367 shares in chain (10488 verified/17371 total)

But for present moment all shares in chain were verified according to log file, what does it mean?

It means your node is still verifying shares - it can take a while if you have recently downloaded the sharechain.

Regarding NMC merge mining - I have posted about my concerns in the NMC forum:

https://forum.namecoin.info/viewtopic.php?f=6&t=2371&p=15989#p15989

Hopefully domob or another dev will look into it. In the meantime, if anyone does actually find an NMC block - please report it, thanks.

I would think that whether or not anyone has actually FOUND a block is not really the question at hand.  The real question is "Do you have a best share higher than the current NMC difficulty AND that share did not mine a block?"

If the answer to that question is yes, there is a problem.

[p3yot33at3r]

Or even more accurately "Does anyone have a best share higher than the current NMC difficulty AND that share did not mine a block?"

I would say probably, yes. But without seeing everyones log it's hard to say. I'm pretty sure that in the months that p2pool users have been using the namecoin-core client for merge mining with p2pool - somebody would have found a valid share & been paid for it......I'd love to hear from that person 

[nicklello]

Has it really been over 5 days since the last block was found ?

[e46btc]

Looks like it was 8 and even 12 days before http://p2pool.info/

Do NOT use p2pool.info - it hasn't worked properly for at least 7 months.

Update on this - I just got the stats through from cassini on the NMC thread - the last NMC block mined by p2pool was exactly 3 months ago, which pretty much matches up with what I thought:

https://forum.namecoin.info/viewtopic.php?f=6&t=2371&p=15993#p15993

I think we need to look a little deeper into the namecoin-core code to try & find the cause - only I don't have a clue where to start

was exactly 3 months ago

Sorry for creating confusion with my slightly unclear post at forum.namecoin.info. Actually it was 3 months ago when the miners had the last chance to mine a NMC block using one of the old Namecoin clients. However, there was a p2pool-mined NMC block six weeks ago, and another one five weeks ago. Both using the new Namecoin Core client.

2015-08-02 23:21 UTC, NMC block 242312, mined by ghash.io. This was the last time an old NMC client was able to sucessfully mine a non-orphaned block.
2015-10-13 21:17 UTC, NMC block 253122, mined by p2pool miner 1GqdAgC1zmzLFMg3XyYctSECWUjkbT7Nv9 using the new Namecoin Core client
2015-10-19 05:10 UTC, NMC block 253874, mined by p2pool miner 14N4xNSDtNYatfCgHhyRaAhdZtaczUBnAa using the new Namecoin Core client

WOW! Really 9 days without a block !

Is this due to lack of hashpower in the pool vs others (ie: everyone else is beating us to it) or simply really really bad luck..

Ah! - that's more like it. Thanks for those stats & putting my concerns at rest cassini - phew!

I'd say it's a combination of all of those. Long blocks happen on all pools though, large & small, luck is luck

Simpler than that: Someone just pissed off one of the Elder Gods.

hi,

to promote the use of p2pool, it would be possible to make it also "shared" the merged mining?

and permit those who connect to a node add own address? For example add own address nmc instead of the password..

Thank you for reply and sorry for my english..

Personaly I do not think it is possible. It would be possible only under condition if each node was merge mining and they are not and they will not. I find it great to may merge mine but the principles of decentralised mining of bitcoin goes counter your idea. imho

so i am mining with high hashrate for 5 days now.. but obviously all my hashpower is being destroyed by "bad luck"..
we are at 16% luck now..
( luck has nothing to do with other pools by the way, just with the difficulty.. orphaned blocks would indicate too much pool-competition )

16% is really bad.. so i am always frightened that something is wrong and we are not noticing it..
and my biggest fear is that i made it broken..

i am merge mining some forgotten coins nobody else is mining ( obviously - i own 90% of the network hash power there, diff quite low. )
so everytime i find a share, i also find 2-4 blocks simultaneously ( each on a different network )

so please tell me that this is no problem for p2pool and i did not break the network.
( it might be confused that one share = 4 blocks on different networks? could that lead to a broken sharechain in p2pool? )

and no i will not tell in public you which networks i use..
( they bring me a 2% bonus on my income.. or with 0% luck... i only loose 98% instead of 100%..  )

concering the merge "bonus": every node operator should definitely set the fee to zero and use the merged coins as his income.. so everybody wins.. ( a negative fee would also be interesting.. but would be quite complicated, as you would have to integrate transactions ("old coins") in the new block )

That's been my paranoia for a few days...
