Abstract

We live in an era where Internet is one of the daily needs of human life. People use Internet banking instead of going to banks, they use email rather than postal mail.This leads to a robust digital way of living, but this also means people are trusting middle companies and third parties for their online services. The need of having a digital form of money that is not being controlled by one entity is plain to see.
Bitcoin is the first and the most popular decentralized virtual currency. It is based on cryptographic functions to remove the need of a central bank and regulates the generation of new units.
In this thesis, we would like to look at available tools to facilitate users in holding and using Bitcoin by a perspective on usability and security, and then evaluate the possibilities for a small business to accept Bitcoin payments. Our focus is on the usability of these tools and developing a useful framework for comparing and eval- uating future tools. While many security tools have been studied from a usability perspective, our work is the first to look at Bitcoin.
