Self-Sovereign Identity (SSI) is an identity model centered on the user. The user maintains and controls their data in this model. When a service provider requests data from the user, the user sends it directly to the service provider, bypassing third-party intermediaries. Thus, SSI reduces identity providers’ involvement in the identification, authentication, and authorization, thereby increasing user privacy. Additionally, users can share portions of their personal information with service providers, significantly improving user privacy. This identity model has drawn the attention of researchers and organizations worldwide, resulting in an increase in both scientific and non-scientific literature on the subject. This study conducts a comprehensive and rigorous systematic review of the literature and a systematic mapping of theoretical and practical advances in SSI. We identified and analyzed evidence from reviewed materials to address four research questions, resulting in a novel SSI taxonomy used to categorize and review publications. Additionally, open challenges are discussed along with recommendations for future work.

“…In one research, a blockchain-backed model of trust was proposed in the field of higher education, to enable training institutions to adapt curricula to match the specific needs as endorsed by employers (Lizcano, Lara, White, & Aljawarneh, 2020). In another research, a trust model was proposed for blockchain-backed identity management, it is based on a numerical trust metric as an independent basis to characterize assurance levels (Grüner, Mühle, Gayvoro, & Meinel, 2018). In the case of tourism crowdsourcing platforms, false data can distort realities hence the rising interest in trust and reputation modeling to assess the quality of the information outsourced from the crowds and its trustworthiness.…”

Since the adoption of the SDGs in 2015, it has been a 5-year journey of trial and error experimentations all over the world to come up with innovative solutions beyond business-as-usual and get the job done. In this paper, we assess blockchain-backed solutions beyond the hype. While the technology has a promising potential to trigger disruptive innovations to fulfill the SGDs, it is not mature yet with many gaps in terms of approaches and tools to develop blockchain use cases, monitor and evaluate blockchain experiments, mitigate associated risks and ethical considerations while managing changes within organizations leading blockchain-powered platforms. It is only by filing these gaps that blockchain can deliver its promises and may be effectively used as an SDG accelerator. Islamic finance can play a key role in shaping the transition towards a more circular economy. One promising way of doing so, is by scaling-up the use of blockchainenabled solutions in the practices of circular economy and Islamic finance. As the technology is still getting mature, more innovative and applied research is needed to capitalize on the lessons learned within various geographies and across a wide range of economic, social, and environmental spectrums.
