that enables secure decentralized transaction processing while ensuring data
privacy and authenticity. It is now playing a significant role in several areas
such the Internet of Things, supply-chain management, manufacturing,
cyber-physical systems, healthcare systems, and much more. Unlike centralized
transaction processing solutions, blockchain uses a distributed ledger
mechanism to record data transactions on multiple devices, this will prevent
data breaches, identity theft, and a plethora of cyber-related attacks, in essence,
leading to sustainability in data privacy and security. This conference aims at
to attract the work of both researchers and practitioners in the area of
cyber-security to share and exchange their experiences and research studies in
both academia and industry in the field of blockchain.</span><span style="font-size:11pt;font-family:Calibri,sans-serif"></span></p>
