Imagine wiring money to a friend, only to learn their account balance and entire transaction history as a result. This is how Bitcoin works today. The Bitcoin blockchain makes publicly available the entire history of transactions and replicates it across all nodes in the network. For the benefits this architecture achieves, Bitcoin comes with fundamental costs to privacy.

In this talk, we will discuss recent research in de-anonymization, transaction linkability, coin fungibility, and blockchain forensics. With legislators and regulators scrutinizing this cryptocurrency, Bitcoin’s anonymity guarantees have far-reaching consequences and legal implications. We will dive into current techniques used to make Bitcoin untraceable, determine its level of anonymity, and discuss recent work to achieve Bitcoin’s privacy guarantees.
