Ran on Ubuntu 13.10 64bit

/GenesisH0# python genesis.py  -z "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" -n 2083236893 -t 1231006505
Traceback (most recent call last):
  File "genesis.py", line 2, in
    import scrypt
ImportError: No module named scrypt

what package I need using APT-GET, thanks


UPDATE:-
Never mind, needed python-pip installed first.
sudo apt-get install python-pip
pip install scrypt construct
and then genesis.py scrypt runs.




but, using these values in X11 scrypt does not work. fine for litecoin scrypt.
Wondering is it possible maybe get scrypt updated to support X11, which is becoming standard now.

Thanks Guys.

here is main.cpp file.


Code:
http://pastebin.com/TSemSTkK

The generating code works fine for scrypt, but for some reason not n-scrypt (X11). I have included complete code of main.cpp.


It seems the GenesisH0 needs update to support X11 scrypt.

Using following code in main.cpp if using n-Scrypt (X11), it gives error when compiling. Any suggestion?

What value have you set for the scratchpad size?

lightenup gave me this advice for generating a genesis block:

Awww, that is cheating!

You really have no business creating your own block chain if you don't understand the code well enough to figure out how to mine a new genesis block without somebody else's help.

Did anyone reinvent the WHEEL lately?

i ran my coin daemon on 2 pcs. And used daemon=1 and addnode=xx.xx.xx.xx (other pc's ip with running daemon)

they never connect.

Thanks it works Smiley need 2 PCs

didnt work for me   Undecided but have fun  Smiley

iirc you can use a --connect=IP argument with the daemon. That should get your nodes to connect to each other.

And apple_talk, you need at least 2 peers in your coins network to mine.

I did use -connect and it says couldn't connect to host server.
Are you sure you have set the ports right?

yeah i cloned doge. which has port 22555 by default

OK, scratch that. Now I have mined a Genesis block, set up some .conf info--how do I mine my new coin? Everything I get from ./coinname getinfo looks right, but I get error 500 when trying to connect minerd...

Whats the next step?

I am also having same question, got everything but now how do I get new coin.

Iirc you now have the valid merkleroot from the debug:

Which you need to put in place of the previous merkleroot you deleted. After you recompile and run the code, it should start hashing a genesis block for you. (if you have the function in place and enabled)

What I did so far:

Change pszTimestamp to a sentence from newspaper
change block.nTime to current time

compile

run compiled source with -testnet -noirc

now u see some lines and a crash
Code:
b115383690ee67ebeef9a7e754342638cd7bbf488561998e6d1bc1ed367484f6 // Block derived from pszTimestamp
b8fa883689f099d3942ff73439d9f55d60a5e257b0d69a8f0f6ab4572ecff415 // Genesisblock (invalid cuz its already coded wrong)
bd58bf217abb76059de07dc519f6c3dcdf5b1a7bb9219a66d24205e08f3716f9 // MerkleRoot (Valid because its newly calculated

corresponding to code:
Code:
        //// debug print
        printf("%s\n", block.GetHash().ToString().c_str());
        printf("%s\n", hashGenesisBlock.ToString().c_str());
        printf("%s\n", block.hashMerkleRoot.ToString().c_str());
        assert(block.hashMerkleRoot == uint256("0xbd58bf217abb76059de07dc519f6c3dcdf5b1a7bb9219a66d24205e08f3716f9"));

update main.cpp with the mentioned merkleroot (it crashed because of the last assert) and run again

you should have already changed the false to true in
Code:
        // If genesis block hash does not match, then generate new genesis hash.
        if (true && block.GetHash() != hashGenesisBlock)

so it will find a genesis block for your string

after a long time you get:
Code:
nonce 003C1000: hash = e8525d8ae8a74a33dbc4b06a64c97ced84dfd29628b3e9e4197c7030cc4a09d3 (target = 00000ffff0000000000000000000000000000000000000000000000000000000)
block.nTime = 1367704866
block.nNonce = 3939341
block.GetHash = fafdbfc957ea6867a0743ff80c4ae126c7dd9fa82057255228a4d58f6ccfdf33
CBlock(hash=fafdbfc957ea6867a074, PoW=000000b1398554a520b5, ver=1, hashPrevBlock=00000000000000000000, hashMerkleRoot=bd58bf217a, nTime=1367704866, nBits=1e0ffff0, nNonce=3939341, vtx=1)
  CTransaction(hash=bd58bf217a, ver=1, vin.size=1, vout.size=1, nLockTime=0)
    CTxIn(COutPoint(0000000000, -1), coinbase 04ffff001d01043741442e6e6c20342f352042657672696a64696e6773646167207a6f6e6e69672c20646161726e61206f6f6b207a6f6d657273207761726d)

  vMerkleTree: bd58bf217a
xx: main.cpp:2070: bool LoadBlockIndex(bool): Assertion `block.GetHash() == hashGenesisBlock' failed.

Now you have the valid Genesisblock and nNonce:
block.nNonce = 3939341
block.GetHash = fafdbfc957ea6867a0743ff80c4ae126c7dd9fa82057255228a4d58f6ccfdf33

Update your code with these values and your ready to go!

this is quite an old thread, but I think it would be best place to post for help.

I changed the ntime to current epoch time, and changed nnonce to 0.

Now i compiled and run the qt. it says assertion failed src\main.cpp line 2870

expression: hash == hashgenesisblock.

Okay, so i went to appdata folder, and then there is qt folder. but there is an empty db.log file, and there is no debug.log file. I run the wallet even through testnet and noirc, still no debug.log file appears. can anyone help?

The key used in the source at
Code:
[s]txNew.vout[0].scriptPubKey [/s]
Is the public ECDSA key for that address right?
I generated an ecdsa key pair, placed the public key in there like litecoin:
Quote
txNew.vout[0].scriptPubKey = CScript() << ParseHex("04f93d54b7873cad866b9d9670717ce5c2d11715e27e35ae55d0b4ee2eb106c9e49d5e8e874b536 04f9c8ae6620b65f685ef9ca90af4686b7f5e0257ae26fd4ce0") << OP_CHECKSIG;
Private key from the pair I changed to WIF and imported to satoshi client with importprivkey call. No coins are showing up. This is the genesis block from debug.log:

EDIT: Nevermind! I just had to mine another block and it showed up.
