Risk Analysis Methodology to Blockchain-based Solutions

Abstract

The success of blockchain-based solutions, not only on a large scale, but since the beginning of the pilot phase, depends on a set of key factors such as performance, efficiency, usability, scalability. In particular, security, privacy and trust are fundamental, as the use of personal data represents, ultimately, immeasurable impacts on people’s lives. This paper presents the results of risk analysis on a blockchain-based self-sovereign identity solution (SSI), focused on the aspects of privacy, security, protection, resilience and reliability. FINID is a blockchain-based SSI solution that aims to create a unique and portable identity that is enriched and used by Brazilians’ financial institutions.
