#GenesisH0 A python script for creating the parameters required for a unique genesis block. SHA256/Scrypt.

###Dependencies sudo pip install scrypt construct

###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
merkle hash: 4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b
pszTimestamp: The Times 03/Jan/2009 Chancellor on brink of second bailout for banks

Create the original genesis hash found in Litecoin

python genesis.py --scrypt -z "NY Times 05/Oct/2011 Steve Jobs, Apple’s Visionary, Dies at 56" -p "040184710fa689ad5023690c80f3a49c8f13f8d45b8c857fbcbc8bc4a8e4d3eb4b10f4d4604fa08dce601aaf0f470216fe1b51850b4acf21b179c45070ac7b03a9" -t 1317972665 -n 2084524493

Create a unique genesis hash with custom pszTimestamp

python genesis.py --scrypt -z "Time flies like an arrow. Fruit flies like a banana."

###Options python genesis.py -h

Usage: genesis.py [options]

Options:
-h, --help            show this help message and exit
-t TIME, --time=TIME  the (unix) time when the genesisblock is created
-z TIMESTAMP, --timestamp=TIMESTAMP
                      the pszTimestamp found in the coinbase of the
                      genesisblock
-n NONCE, --nonce=NONCE
                      the first value of the nonce that will be incremented
                      when searching the genesis hash
-s, --scrypt          calculate genesis block using scrypt
-p PUBKEY, --pubkey=PUBKEY
                      The pubkey found in the output script
