Mine at Jonny's Pool

To those thinking there might be a bug... it's called variance. Take off the tinfoil hats.  p3yot33at3r, I haven't merge mined any coins for a while. However, when I was, I only ever found 2 NMC blocks (maybe it was 3). Back then, a block of NMC was actually worth a little bit of coin on the exchanges. Not sure if jtoomin is merge mining, but it appears he's got the most hash, so he'd have a better chance of finding a block of NMC. Here's from jedimstr earlier: Regarding NMC - If you're using the Namecoin client version 3.80 or older, you won't be able to find a block. Only the newer Namecoin Core clients are supported after BIP66 was implemented. I stopped merge-mining NMC since they haven't had a working client for Mac (yet). I was helping them test new Mac versions a few months back, but the devs were arguing about whether or not to continue to support bitcoin derived QT GUI or another GUI and the test clients they made for me failed at merge-mining (including the namecoind daemon client). BIP66 started to be enforced in July. There are beta clients available for Windows and Linux, but only from the Namecoin forums and not the main Namecoin site which only hosts the now useless legacy Namecoin clients: Details here: https://forum.namecoin.info/viewtopic.php?f=7&t=2354 |

Yeah, I found a few NMC blocks myself prior to the code change to the newer core client, but nothing since then, and from what I can see, neither has anyone else. I'm not saying there is definitely a problem with the core client & p2pool - but think it's worth looking into, just in case.

Well, as long as the implementation of the auxpow code hasn't been touched in the new NMC codebase, then it should work as it previously did. I believe Eligius is still merge mining blocks of NMC successfully.
Maybe forrestv could take a look into it to see if there's an issue.
Of course, my next question: if you are merge mining, have you found a share high enough to solve a block of NMC, but the block didn't get submitted?

Namecoin merge mining works, but there is no sharechain so it basically solomining. There haven't been changes to auxpow. |

I'm not so sure, can you confirm you found a block merge mining with the core client & p2pool? there is no sharechain so it basically solomining
Yes, I'm aware of that. There haven't been changes to auxpow
There have been many changes to auxpow, see the github page: https://github.com/namecoin/namecoin-core/tree/auxpowAgain, I'm not saying that there is definitely a problem with merge mining NMC with p2pool, I just want to confirm that there isn't a problem with it, & until someone can report finding a block while merge mining NMC there simply isn't any proof. I find it strange that since the implementation of namecoin-core, nobody has found one. I think it's just too much of a coincidence & want to make sure. As I said earlier: ...yet everyone assumed it was working fine then also, only it wasn't. If we missed something before, we could quite easily have missed something else, either in the NMC code or p2pool (but I suspect NMC tbh, as all my other merge mined coins are working normally). |

I have not found a namecoin block and would have to look deeper to see if any of my shares met the target. I figure it is working since it says it is receiving work in the logs... Sorry I thought you meant changes to auxpow in p2pool. Perhaps something is wrong?.. |

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.

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 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#p15989Hopefully 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. |

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  |

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

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.. |
