The issue of Blockchain and GDPR compliance is one that will be discussed for some time still and until legislators decide to do something about it. GDPR legislation was passed in a pre-blockchain era and was fashioned with an implicit assumption that a database is a centralized mechanism for collecting, storing and processing of data. Which of course is no longer the case especially with public blockchains. In discussions we had with MEPs, they confirmed that GDPR legislation is meant primarily to protect against very large corporations exploiting their users’/clients’ personal data to make a profit. On the positive side, both GDPR and Blockchain at heart share the objective of data sovereignty, so blockchain could become a tool to achieve this objective. Blockchain could in theory make it easier for platforms and applications to become GDPR compliant by having this compliance inserted in the code, thus supporting data protection by design, one of the law’s primary objectives.
