In our discussion paper "Mythbusting Self-Sovereign Identity (SSI)" (so far only available in German), we take current opinions about SSI in the public domain and critically examine them in the context of seven myths. An English version will most probably also be available in a couple of weeks.

Blockchain-based systems become increasingly attractive targets for cybercrime due to the rising amount of value transacted in respective systems. However, a comprehensive overview of existing attack vectors and a directive discussion of resulting research opportunities was missing up to now.

Thus, employing a structured literature review, we extracted and analyzed 87 relevant attacks on blockchain-based systems and assign them to common attack vectors. We subsequently derived a research framework and agenda for information systems research on the cybersecurity of blockchain-based systems.

We structured our framework along the users, developers, and attackers of both blockchain applications and blockchain infrastructure, highlighting the reciprocal relationships between these entities. Our results show that especially socio-technical aspects of blockchain cybersecurity are underrepresented in research and require further attention.
