Overview

At the beginning of the paper, an overview of the Bitcoin paper is given, focusing on the following

  • If a digital currency that utilizes a Peer-to-Peer communication method is realized, it will be possible to make direct online payments between the parties involved in a transaction without having to go through a financial institution.
