It truly is a wonderful paper. Lots of information in it. You don't need that much background knowledge to understand it, but it can take a few reads to wrap your mind around it.

I would suggest also taking a look at the annotated version of the whitepaper on Fermat's Library:

- https://fermatslibrary.com/s/bitcoin

I wrote some of the annotations and tried as much as possible to make it so that this annotated version would provide a motivated reader with all the resources needed to truly understand the bitcoin protocol.

Michael Nielsen's blogpost about Bitcoin (http://www.michaelnielsen.org/ddi/how-the-bitcoin-protocol-a...) is also a great read.

joaobatalha | 8 years ago | on: Ask HN: What are some interesting papers in CS for a beginner?

"Reflections on Trusting Trust" by Ken Thompson is one of my favorites, and fairly self contained.

Most papers by Jon Bentley (e.g. "A Sample of Brilliance") are also great reads and usually pretty short.

I'm a frequent contributor to Fermat's Library (https://fermatslibrary.com), which posts an annotated paper (CS, Math and Physics mainly) every week. In the annotations you will usually find a concise piece of knowledge that helps you understand some part of the paper without having to spend a long time in the "recursive rabbit hole". For instance, in the Bitcoin paper, there is an annotation with a succinct explanation of the essential cryptography concepts (Hash functions, Public Key Cryptography, Signatures) you need to know to understand the paper. And the nice thing is that if you feel so inclined, you can add your own annotations and make the paper easier to grasp for the next person who reads it :)

I am not the creator, I posted this because we spent way too much time looking for a designer on dribbble, behance, and elance. Users look at the applications and then vote on whether the designer should be admitted
