Abstract

While blockchain technologies leverage compelling characteristics in terms of decentralization, immutability and transparency, user privacy in public blockchains remains a fundamental challenge that requires a particular attention. This is mainly due to the history of all transactions being accessible and available to anyone, thus making it possible for an attacker to infer data about users that is supposed to remain private. In this paper, we provide a threat model of possible privacy attacks to users utilizing the Bitcoin blockchain. To this endeavor, we followed LINDDUN GO methodology to identify threats, and suggest possible mitigations.
