Print Page - How to Clone An Altcoin- Scrypt Coin Edition-Includes Largest Windows Guide Ever

Cloning your own altcoin client can be tricky. This guide is the most up to date reference tool to clone Scrypt coins. The guide is written specifically to clone Litecoin from the current Github repository for Windows users. It includes setting up seed nodes, premines, checkpoints, Github for Windows and few extras not found in other guides.

If you have a Windows machine you can follow this guide to make your own altcoin. I will be adding in the near future clone guide for x11, x13, POW/POS etc. As a clean point of reference each guide will be written specifically for each algo. Linux, MAC and 64bit versions will come though it would be faster to find someone willing to take these originals and edit them over.

If someone is selling you an ICO, you can get all that here for free.

The first full guide is available now at https://howtocloneanaltcoin.com/index.php?topic=8.0. Question will be answered quicker over on these forums instead of this thread.

You need to add the following. (Source (https://howtocloneanaltcoin.com/index.php?topic=9.0))

Code:

if (IsCalculatingGenesisBlockHash && (block.GetHash() != hashGenesisBlock)) {
			block.nNonce = 0;

            // This will figure out a valid hash and Nonce if you're
            // creating a different genesis block:
            uint256 hashTarget = CBigNum().SetCompact(block.nBits).getuint256();
            while (block.GetHash() > hashTarget)
            {
                ++block.nNonce;
                if (block.nNonce == 0)
                {
                    printf("NONCE WRAPPED, incrementing time");
                    ++block.nTime;
                }
				if (block.nNonce % 10000 == 0)
				{
					printf("nonce %08u: hash = %s \n", block.nNonce, block.GetHash().ToString().c_str());
				}
            }
        }
