How do you create an altcoin?

[wmikrut]

I read it and it makes sense... i am away from my dev environment atm.
I will try it though... 5th may be able to confirm as well...

5th got it working via his/her own method, told us in IRC

Nice!!

Currently we're working on an easy (easier) genesis block creation method, and rebranding of the client.

This is fun

freenode: /join #noobcoin

If at first you don't succeed: try, try again.

Progress report?

[wmikrut]

i am refreshing my dev environment and breaking until morning.... its late here in Chicago.  I watched irc for a while and i know theyre making progress there.   More tomorrow..

I'm on the prowl for a genesis block

And best of luck to you!

Very nice work, guys.  Thank you for the thread, and thank you for investing in yourselves.  Do you realize how many more altcoin/bitcoin developers were just born today on this thread?

Still working hard thanks for your interest!

Can someone post some sort of guide, please? Throughout the thread I have lost track of the process (what variables to edit mainly). We also don't really have a post explaining how to get the genesis block started. Sorry, but as the name of the coin suggests (noobcoin) I'm new to this, and don't have much coding experience.

Were you able to work through the instructions in that MultiCoin genesis block page?  I've been aware of it for some time and wishing I had time to try it out.

(Guess I'll live vicariously through you hardworking altcoin devs!)

I'm currently over a billion nonces in searching for a genesis block

When and if it comes out and works, I'll post how to make one.

Hi  

Read this thread about calculating the merkle root: https://bitcointalk.org/index.php?topic=12727.0
It is calculated from the hashes of all the transactions present in the block.

Then, look at this page: https://en.bitcoin.it/wiki/Genesis_block

There is 1 transaction in that genesis block; The first 50 bitcoins.

CBlock(hash=000000000019d6, ver=1, hashPrevBlock=00000000000000, hashMerkleRoot=4a5e1e, nTime=1231006505, nBits=1d00ffff, nNonce=2083236893, vtx=1)
  CTransaction(hash=4a5e1e, ver=1, vin.size=1, vout.size=1, nLockTime=0)
    CTxIn(COutPoint(000000, -1), coinbase 04ffff001d0104455468652054696d65732030332f4a616e2f32303039204368616e63656c6c6f7 2206f6e206272696e6b206f66207365636f6e64206261696c6f757420666f722062616e6b73)
    CTxOut(nValue=50.00000000, scriptPubKey=0x5F1DF16B2B704C8A578D0B)

Transaction hash is '4a5e1e'. (First 3 bytes ?)

The merkle root of the genesis block:

hashMerkleRoot = 0x4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b

and further down the page (read right to left)

3BA3EDFD7A7B12B27AC72C3E67768F617FC81BC3888A51323A9FB8AA4B1E5E4A - merkle root

Maybe the merkle root of the genesis block is the same as the hash of its only transaction?

[Franki23]

I'm very interested in this topic, I'll keep an eye on this, because is interesting how a hashGenesis works, great job!

[tacotime]

Yes, it is.  The merkle root is the root hash of the hash tree for the transactions.  In the case of a block with only a coinbase transaction (the only required one) it's simply the hash of the coinbase transaction.

If you're trying to get the merkle root hash for the genesis block, just hash the coinbase tx twice or SHA256(SHA256(coinbase transaction))

Still working on creating the actual genesis bock.  Marching on.....
