This paper studies users’ privacy perceptions of UTXO-based
blockchains such as Bitcoin. In particular, it elaborates – based on interviews and questionnaires – on a mental model of employing privacypreserving techniques for blockchain transactions. Furthermore, it evaluates users’ awareness of blockchain privacy issues and examines their
preferences towards existing privacy-enhancing solutions, i.e., add-on
techniques to Bitcoin versus built-in techniques in privacy coins. Using
Bitcoin as an example, we shed light on existing discrepancies between
users’ privacy perceptions and preferences as well as current implementations.
