technology in decentralized systems that enables secure decentralized
transaction processing while ensuring data privacy and authenticity. It plays a
significant role in several areas, such as the Internet of Things, supply-chain
management, manufacturing, cyber-physical systems, healthcare systems, etc.
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, leading to sustainability in data privacy and security.
This conference aims 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></span></p>
