Basic example for finding a SHA256 hash and finding a hash with matching pattern
Use npm install to install the dependencies
Start the application with
node index.js
User will be asked to type a word.
Node will then calculate the SHA256 hash value of the work.
It will generate a json sample like a block and calculate the SHA256 hash value of the JSON block.
It will then try to generate a hash value of the JSON block matching the pattern based on the difficulty
