The development of ICTs (Information and Communication Technologies) and the usage of personal data for both research and commercial purposes over the last years have brought the question of the protection of personal data. The GDPR (General Data Protection Regulation) has defined the ways how personal data should be treated, but the application of these requirements still remains an open issue. This paper is dedicated to the research of the blockchain advantages when it comes to providing the transparency of the usage of personal data and provides proof of concept where it demonstrates the application of blockchain in working with users’ consents. Hyperledger Fabric was chosen as the development platform which proves as a suitable choice when it comes to achieving transparency, immutability, and modularity.
