Ok, should I just change some numbers and letters in this line?

Code:

32   uint256 hashGenesisBlock("0x12a765e31ffd4059bada1e25190f6e98c99d9714d334efa41a195a7e7e04bfe2");

No!!!. The genesis block process is not as simple as that. You ACTUALLY need to mine it as a regular block. It's also a process that I don't understand. This is probably the thing that will slow you down the most.

Well if i start mining this genesis block am i not just mining litecoins?

I did not know this. Looks like I'm goint to learn something today!

The problem with github, is it's really really hard to use. I am on Windows, and have absolutely no idea how to use it in terms of committing/merging and so on.

Scrypt 'could' make GPUs useless if tuned a certain way.
I remember reading about this in the forums here sometime last year when GPUs started to dominate Litecoin.

What that tuning was, I could not say.

Exactly. Some variable in Scrypt wasn't set high enough. I believe it's the function at line 263 in scypt.c. The "1024", if set higher should render the algorithm hard enough that even GPU couldn't get an advantage. I'm using my very limited knowledge and my memory of what I read though, so I believe I'm 10% correct Grin

Should I put the binaries and etc. up in this thread when im done?

You should create a github account (it's free I believe) and push your source (and binaries) to your account.
This will be important to keep the project open source and have everything available.

Otherwise you're just creating an RUCoin.

I shall

Lol... people will say all kinds of stuff... I like the thought of exploring the settings for a 'fun coin'.

My guess (and please don't shoot me).... is most of what is needed is in main.cpp as far as default settings go.
Someone with a bit more experience will need to chime in on this one:

32 uint256 hashGenesisBlock("0x12a765e31ffd4059bada1e25190f6e98c99d9714d334efa41a195a7e7e04bfe2");
33 static CBigNum bnProofOfWorkLimit(~uint256(0) >> 20); // Litecoin: starting difficulty is 1 / 2^12

59 int64 nTransactionFee = 0;
60 int64 nMinimumInputValue = CENT / 100;

Block Reward
831 int64 nSubsidy = 50 * COIN;

It seems that everything you need is in main.ccp and main.h. Every other files are "support" files, like to build the keys, define the algorithm and other support functionalities.

As for changing the algorithm, I don't think it's going to be that easy to remove Scrypt and put something else. That Scrypt.c file is scary as hell Cheesy

To be honest I was thinking of doing an alt-coin myself, but ultimately wanted to bring something new on the table in terms of proof-of-work algorithm, as even scrypt proved useless against GPUs.

You can always do a Donkey-Kong proof-of-work :-]]] https://bitcointalksearch.org/topic/m.1812149

You first need to create a genesis block. Even when I asked I couldn't fully understand the process.

I will create a windows binary and a mac if I can. Im just editing files on debian.

And we begin diving into the code, ive got my terminal window open and the git repository cloned Cheesy

Lets go!

Usually when you start making a coin, you have to realize that there are more people on Windows here than on Unix/Unix-like platforms, so a Windows binary is a must. Whereas Linux users can most of the time make;make install it very easily.
