Abstract

The Nigeria Data Protection Act (NDPA) sets a crucial precedent for data protection in Nigeria, and its provisions have far-reaching implications for blockchain technology. As blockchain technology continues to gain traction, it is essential to examine how its decentralized and transparent nature intersects with data protection and privacy. This article delves into the NDPA’s provisions
and best practices for implementing data protection by design in blockchain technology, ensuring the privacy and security of personal data. Our analysis highlights the importance of integrating data protection measures from the outset of blockchain project development to ensure compliance with the NDPA and protect the privacy and security of personal data. We also analyze case studies and examples of successful implementation of data protection by design in blockchain technology, highlighting the benefits and challenges of this approach. Finally, we discuss the importance of aligning blockchain technology with the NDPA’s provisions and best practices, and provide recommendations for blockchain developers, organizations, and policymakers to ensure the responsible development and use of blockchain technology in Nigeria.
