  The Fourth Industrial Revolution (4IR) is transforming the way we live and
work, and education is no exception. To cope with the challenges of 4IR, there
is a need for innovative and sustainable teaching and learning tools. AI and
block chain technologies hold great promise in this regard, with potential
benefits such as personalized learning, secure credentialing, and decentralized
learning networks. This paper presents a review of existing research on AI and
block chain in education, analyzing case studies and exploring the potential
benefits and challenges of these technologies. The paper also suggests a unique
model for integrating AI and block chain into sustainable teaching and learning
practices. Future research directions are discussed, including the need for
more empirical studies and the exploration of ethical and social implications.
The key summary of this discussion is that, by enhancing accessibility,
efficacy, and security in education, AI and blockchain have the potential to
revolutionise the field. In order to ensure that students can benefit from
these potentially game-changing technologies as technology develops, it will be
crucial to find ways to harness its power while minimising hazards. Overall,
this paper highlights the potential of AI and block chain as sustainable tools
for teaching and learning in the 4IR era and their respective advantages,
issues and future prospects have been discussed in this writing.
