The current legal analysis on the blockchain technology focuses on the financial regulation of the cryptocurrencies and little investigation is done in the area of privacy regulation of this technology. This research shows that the blockchains are much more nuanced than could be served by a one-size fits all approach from regulatory perspective. The GDPR implications for the types of blockchains differ. It is possible to achieve compliance with the GDPR if the authorities adopt a nuanced approach and make reliable advance assessments on specific features afforded by this technology. In that regard, innovators ought to be assisted by the European Data Protection Supervisor, Article 29 Working Party and local Data Protection Authorities, in particular, on the question of recognition of the data subject as her own controller by way of implementing specific, electronic identity management techniques on top of blockchains. The utility of the blockchains depend on the GDPR regulators to understand and accept that this technological architecture is best regulated by other technological tools which establish the data subject’s agency on her personal data.
