An Analysis of Anonymity in the Bitcoin System: Bitcoin is not Anonymous.

Bitcoin is not inherently anonymous. It may be possible to conduct transactions is such a way so as to obscure your identity, but, in many cases, users and their transactions can be identified. We have performed an analysis of anonymity in the Bitcoin system and published our results in a preprint on arXiv.

This blog is written by Fergal Reid and Martin Harrigan. We are researchers with the Clique Research Cluster at University College Dublin. The results in this blog are based on a paper we wrote that considers anonymity in the Bitcoin system. A preprint of the paper is available on arXiv.

To illustrate their case, they focus on the alleged thief who stole 25,000 Bitcoins. They make extensive use of flow visualizations.
