Create Genesis Block Proof of Work with Node.js

Tested with Node.js version 12.x.x

setup

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

help

    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
