How to create a Genesis Block for a new Blockchain with Node.js

To start creating a new coin with the Proof of Work consensus algorithm. You need to create a Genesis Block. This’s Lib support create Genesis Block for Bitcoin, Litcoin, Dash, X11, X13, X15, X17, Geek, Quark, Keccak, Qubit, NeoScrypt, Scrypt…

Options:

-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
-a ALGORITHM, --algorithm=ALGORITHM the PoW algorithm: [x11|neoscrypt|quark|qubit|keccak|lyra2re]
-p PUBKEY, --pubkey=PUBKEY the pubkey found in the output script
-v VALUE, --value=VALUE the value in coins for the output, full value (exp. in bitcoin 5000000000 - To get other coins value: Block Value * 100000000)
-b BITS, --bits=BITS the target in compact representation, associated to a difficulty of 1

git clone https://github.com/nasa8x/node-genesis-block.git genesis-block
cd genesis-block
npm install

node genesis -a x11 -z "Don't work for weekends, work for our goals - 18/Jan/2018." -p "04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f"

algorithm: x11
pzTimestamp: Don't work for weekends, work for our goals - 18/Jan/2018.

After creating the Genesis Block, change chainparams.cpp.
