Abstract
Over the last couple of years, we have seen much enthusiasm around blockchain and what it promises. While innovative applications are designed almost every day, blockchain comes with genuine concerns about its security and data protection. This paper discusses the security risks specific to blockchain to take into consideration and how to mitigate them, the limits of using blockchain to record personal information in a stringent regulatory context, and the solutions offered to blockchain developers.
Keywords: Blockchain; data protection; privacy; information security; GDPR; encryption; smart contracts; privacy by design
