45 minutes may not be accurate, but it was an informative article.
Hey OP here, I just found that the article ended here. The idea is that you skim through the article and understand the basic steps to code a bitcoin client.
The steps are:
  1. discover nodes
  2. connect to a node
  3. create a bitcoin address
  4. fund the address
  5. create a transaction
  6. broadcast the transaction
When you get the steps, you can run the nodejs scripts and the if something does not add up you can look into the code more closely.
I totally get that to really understand what is going on you'd need much more than 45 minutes. Just aimed to help people understand the building blocks before the spend more time into the protocol details.
