Holistic Privacy and Usability of a Cryptocurrency Wallet

Harry Halpin

Abstract: In this study, we overview the problems associated with the usability of cryptocurrency wallets, such as those used by ZCash, for end-users. The concept of "holistic privacy," where information leaks in one part of a system can violate the privacy expectations of different parts of the system, is introduced as a requirement. To test this requirement with real-world software, we did a 60 person task-based evaluation of the usability of a ZCash cryptocurrency wallet by having users install and try to both send a… Show more

“…Ljunggren [20] defined criteria for evaluating the top five Ethereum mobile wallets which are inspired by Norman [28] and conducted a user study to evaluate the wallets and then provided an application structure to improve the wallets based on their findings. The usability of the Zcash wallet was studied in [14]. It found that most of the users failed to purchase a real item using the wallet due to the complexity of the installation and integration of the wallet with the network-level protection tools.…”

“…The goal of designing privacy-enhanced software should be easy-to-use software that preserves the holistic privacy of users. As our study showed, it is difficult for even highly motivated and technically adept users to use anonymous cryptocurrency wallets at the present moment in a way that preserves their holistic privacy due to the fundamental disconnection of network level and on-chain anonymity (Halpin, H. (2021) [47]). A centralized exchange where a trusted party receives tokens on the different ledgers and transfers the exchanged tokens accordingly based on some centrally decided exchange rate.…”
