Anonymity is not a prominent design goal of Bitcoin. However, Bitcoin is often referred to as being anonymous. We have performed a passive analysis of anonymity in the Bitcoin system using publicly available data and tools from network analysis.

We note that several centralized services, e.g. exchanges, mixers and wallet services, have access to even more information should they wish to piece together users' activity.
