Hi, I have been on this forum for a while, figured I would try to contribute what I can. I can create an altcoin for you within 48 hours if you want. We can use an escrow service if you choose, or you can pay in increments. PM me if you are interested.
PM me with:
Coin Name
Coin Symbol e.g. BTC
Algorithm: (I will do SHA256, Scrypt, X11, X13, or X15)
Total Coins
Coins per Block
Premine amount (if any)
Time per Block
RPC port number
P2P Port number
Icon (png format, make sure it is 256x256 or above, and height=width)
Splash Image
Package:
Windows QT wallet
Source code
1 Node hosted for 6 months
Premine coins if you choose. (you just send me your coin address)
Price:
0.4 BTC

NO MORE PREMINE GET OFF
How else can a coin offer anon bounties, offer giveaways, and have other kinds of bounties? I'm also a bit skeptical over this statement, but I don't believe that someone would use their own BTCtalk account scamcoin. They're practically asking for an infamous reputation if thats the case.
I agree, this seems legit. |

Awesome! Will be mining this  |

WTS 300 WHC. PM me with offers. Can do small increments.

I remember koolio bragging on btc-e about waiting until Litecoin hit $100 to buy a Lamborghini lol

Thanks. I am running the powershell qt script now from the qt website. Going to try and build a static version. If that doesn't work, I suppose I will have to just keep tinkering. Frustrating seeing as how the linux version runs perfectly. I hate Windows  |

What source is your coin based on? Likely needs static-Qt compilation if its a newer one...
Blackcoin. Maybe you are right. I have tried almost every qt version from 4.8.5 and 4.8.6, to 5.1.1 and 5.3.1 |

I successfully built my coin on my laptop using Qt4.8.6, but get this error when I try to solo mine it. I can solo mine, but the error pops up. If I click 'ok', it shuts the program down and I can't open the program anymore without seeing this error and it automatically shuts it down.
On my desktop, I built the coin using Qt 5.3.1, and it gives the same error immediately upon opening the client. I can't click on any of the program buttons at all.
Any ideas? I have tried building with different version of qt and mingw, to no avail.
I think it is a problem with the rpc part of the build. It crashes when mining, and also in the debug section if you type in 'help' or an unsupported method. All the other methods work fine.

Some more details on your build environment please. What version of GCC are you trying to compile with?
I am thinking that is the problem. From a Windows command line, if I call , it says 4.8.2. However, if I call the g++ executable in C:\QtSdk\mingw\bin, it is version 4.4.0. From what I have found online, this may have been fixed in a later version. I tried replacing the g++ executable with the one from my PATH (in C:\mingw32\bin), but it gave me a CreateProcess: no such file error. I downloaded an updated mingw folder from here: http://ic3man5.wordpress.com/2012/03/04/updating-mingw-gccg-for-qt-creator-windows/ and am going to replace the mingw folder in C:\QtSdk. Hopefully that will work. EDIT -- That fixed it! I updated g++ using the link above. Now I am getting other problems though, such as cannot find -lboost_filesystem-mt multiple definition of 'std::out_of_range::~out_of_range()' Will keep working on it |

I think I managed to get all my dependencies and libraries right (fingers crossed), but now when trying to build blackcoin-qt, the QTSdk compiler gives me this error while building qtipcserver.o: In function 'bool boost::interprocess::winapi::unlink_file(const char*)':
internal compiler error: in gimple_rhs_has_side_effects, at gimple.c:2343
[build/qtipcserver.o] Error1
The unlink_file function is on line 1638 of win32_api.hpp in the boost library. This seems like a GCC error, any ideas? |

Thanks for the guide! I know this is old, but hopefully someone will answer!
I successfully created the genesis block hash and the merkle root, and recompiled the code with the correct assertions. However, I now get an error when I open the program that says 'Error loading blkindex.dat'
What should I do about that? I deleted the blockchain files and still get the same error.
It is the blockchain telling you to not create another shitcoin. Jokes aside, this is the genesis block not accepted due mismatch error. You are using either wrong genesis creator code or did something else wrong. Google and figure it out. This is really more of a personal project really, but thanks for the answer. I found what I did wrong and successfully created a good genesis block and recompiled. Now, my wallet loads fine. However, I am still a bit confused. I forked this testcoin from the Blackcoin source code. When I load it up, it says it has xxx connections to the network, and says it is downloading block 0 of 193113 blocks in the chain. Does this mean that it is still somehow trying to load the Blackcoin blockchain? I'm guessing the nodes are built into the Blackcoin wallet somewhere? EDIT -- I figured it out. In case anyone else has this problem, the nodes are built into /src/net.cpp |

Sorry for my noobish question, but I have been perusing the bitcoin source code and I can not find where exactly the sha-256 pow is implemented. I can see where the hash is defined in src/hash.h, but I can't find where it's used. Thank you.
Is this what you're looking for? main.cpp bool CheckBlockHeader(const CBlockHeader& block, CValidationState& state, bool fCheckPOW)
{
// Check proof of work matches claimed amount
if (fCheckPOW && !CheckProofOfWork(block.GetHash(), block.nBits))
return state.DoS(50, error("CheckBlockHeader() : proof of work failed"),
REJECT_INVALID, "high-hash");
Thanks, I'll take a look at that. I'm also looking at source codes with other PoW algorithms, to see how exactly someone goes about implementing their own hash function. |

What is Mintpal's problem? I have never seen them take this long to add a coin doing this level of volume! This week they added Information coin from the voting, have you seen it's daily volume? Less than 5.5BTC today on Mintpal.... Unbelievable. They are shooting themselves in the foot. This is another reason I am really moving to Bittrex as my main exchange. They don't hesitate to add coins. None of this bs greedy voting scheme.

See title. This coin is not yet on any exchange. PoW is ended.
