How do you create an altcoin?

[bitcool]

Make a noob_x_coin DIY guide, and sell it for btc/ltc. I am sure there are people who are interested.

I'll put it up here for free

It would be cool to get some altcoin devs in here, were are all of them? :3

Busy with their coins!

Ok, I belive im done editing the variables, I left some alone because I didn't know what they did but I edited the ones that I understood and wanted to. Onto the next step?

Update the code for the genesis block

How do we do this?

[wmikrut]

The genesis block is created from this piece of code

       const char* pszTimestamp = "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" //<- change this to something else;
        CTransaction txNew;
        txNew.vin.resize(1);
        txNew.vout.resize(1);
        txNew.vin[0].scriptSig = CScript() << 486604799 << CBigNum(4) << vector<unsigned char>((const unsigned char*)pszTimestamp, (const unsigned char*)pszTimestamp + strlen(pszTimestamp));
        txNew.vout[0].nValue = 50 * COIN //your premine basically;
        txNew.vout[0].scriptPubKey = CScript() << ParseHex("<public key from an ECDSA keypair>") << OP_CHECKSIG;
        CBlock block;
        block.vtx.push_back(txNew);
        block.hashPrevBlock = 0;
        block.hashMerkleRoot = block.BuildMerkleTree();

Now you mine that.

This is the code for the genesis block.
I am very unclear here... if this is a part of the code base, or a part of 5th's Genesis Block finder.

In addition 5th said you need a valid Merkle root... that the one in his code was for illustration.
Someone with experience will need to chime in on that one.

What is the Merkle root?

Truth be told I dig deep and deep in Bitcoin's source and it does some kind of serialization of objects and stuff and finally produces a merkle root hash..seriously ridiculously hard to even figure out what the hell happens.

I would like to create a coin :O, one that is not GPU dependent. I have been developing a FPS on and off the last year so perhaps I could create a video game and you mine coins in game? I actually also like the idea of creating a coin that some how rewards ethical work. Can anyone point me to a tutorial, preferably noob proof.

There are no tutorials, thats why this thread was created

OMG! I was just thinking this

[wmikrut]

Best I can find:

Merkle root
Every transaction has a hash associated with it. In a block, all of the transaction hashes in the block are themselves hashed (sometimes several times -- the exact process is complex), and the result is the Merkle root. In other words, the Merkle root is the hash of all the hashes of all the transactions in the block. The Merkle root is included in the block header. With this scheme, it is possible to securely verify that a transaction has been accepted by the network (and get the number of confirmations) by downloading just the tiny block headers and Merkle tree -- downloading the entire block chain is unnecessary. This feature is currently not used in Bitcoin, but it will be in the future.

However... it's still nebulous as to 'how' it's initially created.

Have we come to the consensus that no one in this thread (currently) knows how to start going about creating the genesis block?

[jackjack]

I know there's an old post in this forum that explains clearly how to make that genesis block
