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>
