This chapter focuses on the intersection of self-sovereign identity and
blockchain technology. This review encompasses a number of issues: the role of SSI in
augmented identity management, the advantages and challenges of blockchain
integration, and real-world applications. It looks at how these technologies can make
identification processes more efficient, secure, and reliable. The current review
elaborates on the impact of SSI and blockchain on identity management with the use of
selected papers from previous years. It is here that the main benefits, as well as
practical challenges, are identified with the implementation of the technologies. The
provided study concludes that SSI and blockchain technology have enormous potential
to make identity management an order of magnitude more acceptable for various
application domains. This will help shed more light on further research with an
understanding of the benefits and challenges of these technologies.
