## Create Genesis Block Proof with Node.js
## setup
```js
git clone https://github.com/nasa8x/node-genesis-block.git genesis-block
cd genesis-block
npm install
```
## help
```js
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
```
