A Psuedo Guide on how to Build an AltCoin (help fill in gaps)

[c4n10]

Best. Thread. Ever.

I think everyone should have instructions readily available on how to create a new crypto. Someone who has a great idea for a new crypto that may not be strong in programming can probably learn a lot with some basic instructions and a little practice on building a couple of basic forks on his way to learning how to perfect his dream coin.

I will be monitoring this thread for sure  

Everyone who wants to hide how to build an alt-coin should be ashamed of themselves. Satoshi gave us Bitcoin in the spirit of open-source, new coins should be encouraged, not hated on.

Bitching that all these new coins are ruining the profitability of your chosen favorite coin is not in the spirit of open-source, it is in the spirit of greed.

Bitcoin was created as an alternative currency solution to be adopted by societies so they could stop using money backed by gold that drives their countries further into debt with every dollar they print, it was not created to be your personal "get rich quick" scheme.

The sad part is most of you who bitch about people cloning OPEN-SOURCE software are the same people who bitch when a client comes out that doesn't want to share it's source code

Helpful & informative thread, thank you.

Advice on Compiling litecoin based code on windows:

(important since the small change code is based on litecoin)

Been playing and managed to successfully compile the daemon after making some of my own changes.

Not having too much luck compiling the wallet though. This is the error I get:

Anyone have any ideas?

My advice make a new thread in the development say forum but post a link to it in this thread, you'll get more responses and people will be able to find the info

I've gotten to the point of have a working coin on 3 computers, connected via addnode= in their coin.conf with ports forwarded and such:

adam@server ~/coin/src%./coin getinfo
{
    "version" : 60300,
    "protocolversion" : 60001,
    "walletversion" : 60000,
    "balance" : 0.00000000,
    "blocks" : 0,
    "connections" : 3,
    "proxy" : "",
    "difficulty" : 0.00024414,
    "testnet" : false,
    "keypoololdest" : 1368206160,
    "keypoolsize" : 101,
    "paytxfee" : 0.00000000,
    "mininput" : 0.00010000,
    "errors" : ""
}
adam@server~/coin/src%./coin getmininginfo
{
    "blocks" : 0,
    "currentblocksize" : 0,
    "currentblocktx" : 0,
    "difficulty" : 0.00024414,
    "errors" : "",
    "generate" : true,
    "genproclimit" : -1,
    "hashespersec" : 0,
    "networkhashps" : -9223372036854775808,
    "pooledtx" : 0,
    "testnet" : false
}
adam@server ~/coin/src%

Unfortunately, I can't get them to mine--how do I start? I have them all set to gen=1, yet I see no mining and I can't connect via RPC (minerd) I just get error 500 but I can see them listening via netstat -a on port 7850 (the one I changed the SMC code to). Anyone know how to get these to start mining?

How to up-vote?

Bumping this.
Great guide. I am following it almost to a 'T', and it's coming along smoothly.
I am about 90% into launching a new alt (just waiting on some libraries to install for compiling purposes, etc).
I have a novel concept and would like some collaboration.
Anyone interested? Message me on skype for more details.

I am also making a guide for creating an altcoin, will post it soon. Its a detailed guide for people, who haven't programmed before, but are interested in creating an altcoin.

Make sure it is more up-to-date than these:

This is a great guide. Right what I was looking for! It just leaves me to know if having and maintaining a Bitcoin Faucet is still profitable.
