The European Parliamentary Research Service has published a study asking if distributed ledgers be squared with European data protection law? It points out that GDPR is based on an underlying assumption that in relation to each personal data point there is at least one natural or legal person – the data controller – whom data subjects can address to enforce their rights under EU data protection law. GDPR is also based on the assumption that data can be modified or erased where necessary to comply with legal requirements. The study sets out to examine the European data protection framework and applies it to blockchain technologies so as to document these tensions. It also highlights the fact that blockchain may help further some of the GDPR objectives. Concrete policy options are developed on the basis of this analysis.
