GenesisH0

A python script for creating the parameters required for a unique genesis block. SHA256/scrypt/X11/X13/X15.

Dependencies

sudo pip install scrypt construct==2.5.2

To create geneses based on X11 algorithm you will also need to install the xcoin-hash module. For X13 you will need the x13_hash module and for X15 the x15_hash module.

Examples

Create the original genesis hash found in Bitcoin

python genesis.py -z "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" -n 2083236893 -t 1231006505

Output:

algorithm: sha256
