Abstract

This paper investigates the anonymity of bitcoin transactions and the significance of awareness of the technology by bitcoin users, alongside their experiences in tracing transactions. Bitcoin enables users to carry out transactions anonymously with the virtual currency they possess without unveiling where the real-world source of the income has come from. These transactions may occur without revealing the location or any personal identifiable information of the person who is sending or receiving bitcoin. While there are existing surveys which test bitcoin user’s awareness of the technology, they do not focus on bitcoin user’s own experience using the technology in terms of tracing transactions and use of anti-forensic tools to increase the level of anonymity. This paper reports significance of user opinions on tractability and anonymity of bitcoin transactions and compare the user viewpoints from the survey with experimental observations using network analysis.
