Title:
User-Perceived Privacy in Blockchain

Authors: Simin Ghesmati, Walid Fdhila, Edgar Weippl

Abstract:

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 privacy-preserving 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.
