NEW EFFICIENT CPU MINERI might be working a CPU only miner on the weekend, and will probably release it as open source.
For those of you who asked about the CPU miner, good news: The new version of the miner supports both GPU and CPU mining. As i'm not sure if the GPU version runs without a GPU driver installed, i produced 2 versions of the miner: minerd.exe which supports both CPU and GPU, and minerd-cpuonly.exe, which as its name says, supports only CPU mining. as always, downloads are here: http://girino.org/metisminerThere are no news in the GPU miner, so you only need to update if you intend to do CPU mining. Please enjoy all of you, and happy mining.

concateno os 2 string: ���=�P>o=����Z�I�*���(J���m���R[�1@-В"�u`�ux{Ҹ~V�Z{�0���
o hash disso é: 204ee246463fecd48b2071a6512204cf952a006f8fc08bb61d0cbd8f53b063e0
mas o esperado seria ccdafb73d8dcd0173d5d5c3c9a0770d0b3953db889dab99ef05b1907518cb815
Não sei como você fez, como eu disse, não entendo de PHP, mas fiz aqui em python rapidinho: a = '8c14f0db3df150123e6f3dbbf30f8b955a8249b62ac1d1ff16284aefa3d06d87'
b = 'fff2525b8931402dd09222c50775608f75787bd2b87e56995a7bdd30f79702c4'
#converte pra binario
a_bin = "".join([chr(int(a[i-2:i],16)) for i in xrange(len(a), 0, -2)])
b_bin = "".join([chr(int(b[i-2:i],16)) for i in xrange(len(b), 0, -2)])
result = sha256(sha256(a_bin+b_bin).digest()).hexdigest()
print result
o resultado deu "15b88c5107195bf09eb9da89b83d95b3d070079a3c5c5d3d17d0dcd873fbdacc", que é o que você esperava. Ah sim, acabei de conferir. Sua entrada está invertida... você tem "  =?P>o=????Z?I?* (J??m?" quando na verdade deveria ter "?mУ?J( *?I?Z???=o>P?=???". O mesmo deve acontecer com a segunda entrada (não conferi). |

estou tentando entender o mrkl_tree li varias paginas mas não ta dando certo aki estou tentando repodruzir o bloco 100000 que tem so 4 transações http://blockexplorer.com/rawblock/000000000003ba27aa200b1cecaad478d2b00432346c3f1f3986da1afd33e506estou tendo como resposta e0172299a5f4721b039a8a759f84fc7457dfe14296a6b39b32140feb32bda194 enquanto o esperado e ccdafb73d8dcd0173d5d5c3c9a0770d0b3953db889dab99ef05b1907518cb815 eis meu código php function inv($in){ $split = str_split(strrev($in)); $x = ""; for($i = 0; $i < count($split); $i += 2){ $x .= $split[$i + 1].$split[$i]; } return $x; } function h($value){ return hash("sha256", $value); } $a = inv("8c14f0db3df150123e6f3dbbf30f8b955a8249b62ac1d1ff16284aefa3d06d87"); $b = inv("fff2525b8931402dd09222c50775608f75787bd2b87e56995a7bdd30f79702c4"); echo h(h($a.$b)); As strings estão em hexadecimal, vc precisa de strings binárias pra gerar a hash. Não conheço PHP mas você provavelmente precisa de algo como: $x .= char(int($split[$i + 1].$split[$i], 16)) (i.e., converte o hex pra inteiro, depois converte pra "char".) |

Sorry everybody! the pool has been down for almost half an hour without me noticing it. (i was sleeping late). Mysql has crashed because of low memory. I upgraded the memory in the server and relaunched it. should be up by now.

@Girino. Will move all workers over to your pool later today/tomorrow morning! Am currently mining 1x 6850, 1 x 6870, 2 x 660ti, 1 x 7970. Have ordered 2 new 6870's i hope will arrive monday.
You have done an awesome job Girino!
Thanks, that will help the pool (and the coin) a huge lot! |

girino:
Can you increase to 5% and give 1% to the developer team for promotions?
Well i was planning on spliting the proffits (i.e. what is left after i pay the VPS) between the devel, gigawatt (who developed most of the opencl code) and myself. But i don't think we'll make proffit before we have 1GH/s on the pool. So i'll keep it at 4% for now and hope for proffit  |

The new miner can operate in an efficient way, even in CPU-only mode? Sources for Linux? TIA no cpu-only mode yet. As i cannot efficiently charge a developer fee on this miner, i'll release the sources only after the pool is stable and making some proffit. (or if a receive enough donations to keep the pool running for 2 or 3 months). I might be working a CPU only miner on the weekend, and will probably release it as open source. |

Hi all, I think every aspect of the pool has already been tested. We are steadily making i block every hour. The promised 10 blocks beta period will be over soon. So here comes the bad news. I'll need to pay for the VPS where the pool is running  So to cover those expenses, i will be seting up a 4% fee. As the rates are volatile these these days, i have a 50% chance that this will cover the expenses. If the number of users/miners in the pool increases, i'll be reducing the fee accordingly. This fee is significantly lower than on ypool since there are no "miner" fees included. On ypool, unless you build your own miner, there is a 3% extra developer fee charged by the miner, totaling 7.5% fee. On my pool, fees are ONLY 4%, no miner fees! Fees will start on saturday around noon BST (GMT-3), so you still have 24h+ to mine without fee. Please, do not leave the pool after the fee is set, but rather invite more people to it so i can lower the fee even more. Thanks in advance girino. |

New version of the miner for my poolSome of you requested changes, i made them! New build 3 of the miner available at the same place: http://girino.org/metisminer/New on this version: 1- option -d now supports more than one device (old syntax, -d 0,1,2,3 etc) 2- option -I for "gpu intensity" (same as -s on ypool miner, but -s was taken by some networking options). USE WITH CARE, values too high might freeze the program, values too low will be rejected by the GPU. Default is "-I 19". I don't recommend values above 25 or bellow 15. I still have to implement an efficient CPU miner. The default implementation (that comes wth the wallet) is even slower than using opencl on the CPU device. So for those looking for CPU mining, i'll work on it for next week. Thanks to all for the support, and happy mining. Tried to download but says forbidden. oops, i did it again! Problem solved! |

My antivirus blocked malware from one of these pools. Just disgusting, really.
could you please tell us which AV was it? i'll try to contact them and have them stop reporting it as virus... |

The miner is based on pooler's cpuminer, which is considered by some AV software to be a virus |

Maintenance and backup (should not take more than 5 minutes)
Hi all,
I'll be taking the pool down for at most 5 minutes in order to upgrade the server (a better VPS, more memory, more processing power) and make an image of the VM in the meantime.
This should not take more than 5 minutes, if it takes that long! Please be patient if your miners stop for some seconds!
Done! Everything went as expected. You can now resume your mining! |

Great news everyone! The pool just broke it's first block one hour ago! Now we'll be able to test the payout system! YAY!  |

how to use CPU rather than GPU to mine in girino pool?
I'm still strugling with the server (now the load is getting high, i'll try to set up a better VPS for it). I think after the beta (i intend to make it as long as it takes to break 10 blocks) i'll have all the improvements to the miner done. |

I can't download the new miner:
Forbidden You don't have permission to access /metisminer/metis-minerd-win64-cygwin-build2.zip on this server.
Sorry, i uploaded in a hurry and files got the wrong permissions. should be fixed by now. |
