libboost-all-dev is already the newest version. What boost version do you have? |

Mr. Spread what formula you use to calculate "Average spacing between blocks"?
2^256/(Target*Hashrate) where target comes from the last block and hashrate is the hashrate of the built-in miner. |

i have troubles with sgminer and spreadminer from this topic
maybe x64 is the reason ?
"I have troubles" doesn't really tell much and I don't know about the sgminer version but I'm happily running the CUDA miner on Win 7 x64 so that probably isn't the problem. sgminer crashes at start i tried on x32 & x64 win 7 7970, catalyst 13.12 & 14.4 the same result  me too,280x crashes on catalyst 13.12 & 14.4 This is error during OpenCL kernel compilation, seems like a bug in the gpu driver. Are you setting gpu-platform? Try to run "sgminer -ndevs", e.g. from bat file: for me it shows that I have two platforms - intel and amd, by default it tries to use intel integrated gpu and it doesn't work (but with different error). I specify "--gpu-platform 1" to use amd gpu. Even if you don't need to specify gpu-platform for other versions if sgminer this may still be necessary for this miner for some reason. I have driver version 14.301.1001.0 on Windows 7 x64, it works. Dev,plz use sgminer 5.1 which is most compatible with all kinds of AMD GPU.
But not with mine. |

AMD miner does not compiling under ubuntu 12.04 (32&64). I got this: driver-opencl.c:1219:5: warning: implicit declaration of function ‘max’ [-Wimplicit-function-declaration]
driver-opencl.c:1219:29: warning: initialization makes pointer from integer without a cast [enabled by default]

but at configure this: OpenCL...............: FOUND. GPU mining support enabled And the linux x64 build wallet does not opening rpcport 41677. Why? Update the source, should be fine now. |

My immediate plans are:
1. ...
2. ...
3. Make block explorer inside the client. I already have some working code but it is yet incomplete.
4. ...
Is this going to be implemented? Tools -> Blockchain Explorer. You may want to set txindex=1 and addrindex=1 in your spreadcoin.conf to get the full information in explorer. |

Quite a few people submitted logos for contest in recent days, we will have many variants to choose from.
|

few hours, i just need to make final fixes, builds and tests and gpu miner will be yours.
|

Mr Spread, how's the GPU miner going? Is it going to be released really soon?
Yes, I a little bit underestimated the complexity when I said that it will be ready in 2 days but I am working hard it is almost ready. What we are talking here are a few days at most. |

I still have only two submissions for logo contest. Voting for logo will start at 21 November; this date will not be moved again.
I will again contact everyone who posted logos in this thread and ask them to choose the final variant(s) that they want to submit for contest. If you posted 10 logos in this thread (which is great) then don't expect me to choose the logo(s) that you want to send to contest for you (to submit logo to contest just PM me).

can i make the greek translation?
Yes, we need translations, there is reward for that |

Looks like it would be possible to get around 500 kh/s out of amd r9 280x but I'm sure that by tuning some parameters you would be able to get more. Miner isn't ready yet, last missing piece is yet to be implemented, currently it generates invalid blocks. Will release it as soon as it is ready, probably 1-2 days. Does anyone know how long it is until we start voting for logos?
In fact voting was supposed to start today. But there are just two submissions even though I contacted everyone who was posting logos in this thread, maybe I didn't make it clear that voting should start today and people think that there is more time. I really need to sleep now, I was working on this miner for many hours today (and not only today), will decide tomorrow what to do with this situation, probably we should give people some more time to submit logos. |

well, a small change might be something that requires huge amounts of memory, or even to use diskspace in order to be calculated, which makes the use of GPU so slow that CPU are still usable for mining. (take a look at the momentum algorithm used on protoshares, miners are only 2 or 3 times faster on GPU).
Requiring to use disc space is surely not a small change. Their whitepaper seems to be outdated, when reading it the first thing I thought was that you can use bloom filter to significantly reduce memory requirements. Some googling revealed that someone else already pointed to this and other vulnerabilities in the proposed scheme were found. They seem to fixed them to some extent but its not fast to find any definite information. This all will require time, I can't just copypaste some code into SpreadCoin without understanding it. GPU miner is my priority now. |

I will send this message to everyone who posted logos in this thread. You need to submit logo (or several logos if you want) before the end of this week. You can PM me or post it in this thread with a clear statement that this is the final variant of your logo. Your logo must be 512x512 png with alpha channel. According to the rules it is also necessary to submit additional images. Almost no one makes these additional images so I will allow everyone to participate even without them but submitting them is a plus. You can also choose to use original images if your logo is using the same color scheme. |

We can make a smart change and a fork to stop this gpu miner. This will give us some time but eventually there will appear a new gpu miner. What we'll do next, another fork? And then again and again... This is the wrong solution.

Stopping mining now is a very bad idea. This miner seems to be kind and not using his power at full capacity, hashrate is about 8-9 MH/s, this is not something we never saw with CPU-only miners. It is the last chance to mine with your CPU, soon it will be impossible.
I started to work on an AMD miner, I haven't previously done anything like this, hard to say how long will it take.
And what about the hardfork witch slighly changed algo? Miner included in wallet will include this change and private gpu miners will need to redesign their software. Smart change in algo will sloooooooow down this redesign. Small change to the algo implies small change to the miner. This may give us a few hours or a day at most. |

out of curiosity can you post a diff between spreadx11 and standard x11
1. Each block is signed with the same key which is used in coinbase transaction and this signing must be performed in mining loop. 2. It is necessary to recompute whole block hash during mining. These two things proof miner's knowledge of the whole block and ability to spend coinbase transaction. This prevents trustless pools because upon finding a block miner can broadcast it directly to the network and spend its reward. |

Mr. Spread, since we need a bigger exchange, could you edit OP and post C-CEX on top with logo linked voting? Maybe it will attract more voters. And by the way, you should start thread in Altcoins/Mining section with bounty for miners. Later it could an official thread for SpreadCoin miners.
Done and done |
