To properly understand technology like this, I need to sit down and crunch the numbers, program it up, and learn from that.

I can't find any technical, low-level documentation on the IOTA protocol.

One example is Dom's gitbook were some details are explained, but most is just references to functions of the API/Library - Not how a seed is used to create private keys and addresses, changing those trytes into numbers and then into the cryptographical world.

Does anyone have any links or PDFs, or do I have to take a deep dive into the source code?
