This was an excellent article Mohit, thanks so much for writing it. I’m going to direct anyone to this page anytime thay ask me what’s blockchain/bitcoin. I have a couple of followup questions:

  1. How and who decided the output (in your example, word starting with 000) in the first place?
  2. Does this output stay the same forever or does it change over a period of time?
