Two things:

  1. In the "Genesis block" section you have "Their must be", it should be "There must be".
  2. "check the validity of a hash => does our hash starts with 'OOOO'" weirdly this gets formatted like it has four letters "O" instead of zeros?

Aside from that, it is a good article and thank you for posting it :)
