The rapid expansion of digital technologies and the emergence of blockchain as a novel platform for data exchange and storage have raised multiple challenges in the field of cyber law. Among the most significant of these challenges is the conflict between the “right to be forgotten,” recognized as a fundamental right for privacy protection, and “data permanence,” which constitutes an inherent characteristic of blockchain technology. The central research question of this study is how a balance can be struck between these two seemingly contradictory principles. The importance of addressing this issue lies in the fact that the right to be forgotten, especially after the adoption of the General Data Protection Regulation (GDPR) in the European Union, has become a global legal demand, while blockchain relies on the immutability of records, placing these principles in direct opposition. The objective of this article is to examine the legal and technical dimensions of this conflict and to propose approaches for achieving a relative alignment between legal norms and technological requirements. The research method is descriptive–analytical and document-based, relying on legal sources and technical reports to provide a comprehensive understanding of the issue. The findings indicate that although the enforcement of the right to be forgotten within blockchain systems faces considerable limitations, it can be partially realized through innovative approaches such as off-chain data management, encryption of access keys, and hybrid frameworks integrating technological and legal solutions. The novelty of this paper lies in its shift from a binary opposition between the right to be forgotten and blockchain permanence toward a conceptual framework that emphasizes coexistence and convergence of the two principles through combined legal and technical mechanisms.
