The 7th International Conference on Blockchain Computing and Applications (BCCA 2025)

14–17 October, 2025 – Dubrovnik, Croatia

CALL FOR PAPER



Blockchain is a revolutionary technology in decentralized systems 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 breach, identity theft, and a plethora of cyber-related attacks, in essence, leading to a sustainability in data privacy and security. This conference aims at to attract 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.
