Session teaser

Huge centralized data collections are one of the main threats to privacy. They can be abused by large corporations, hackers who breach firewalls and secret services. Blockchain omits centrally controlled data collections and can provide better privacy protection in some cases. At the same time Blockchain means immutability and lack of central control. Data protection however, includes the right to be forgotten, requires regular deletion and assigns responsibilities to controllers of data processing. Is privacy regulation like GDPR an obstacle to the use of privacy, enhancing peer-to-peer technology like blockchains? Can blockchains be GDPR-compliant? What are the best practices?

Session description

The session discusses blockchain technology and its impact on privacy. Public blockchains offer transparency and immutability while the General Data Protection Regulation (GDPR) demands that the right to be forgotten is honored and imposes restrictions that are hard to be implemented on blockchains. The session will present technological approaches to ensure a high protection of privacy and will discuss remaining frictions between blockchain, privacy and GDPR.

The session will discuss technological approaches like the use of hashing or zero knowledge proofs. There will be presentations of systems for self-sovereign identities (SSI) and the verification of diplomas through smart contracts on public blockchains. Legal aspects such as how to attribute the GDPR-roles of controllers and processors to peer-to-peer technology or when hashes need to be considered as personal data will also be included in the session.

The session will conclude with a presentation of different initiatives that are trying to standardize privacy on blockchains at the DIN in Germany, the ITU, the ISO and JPEG organizations.


The session will start with a series of lightening talks about blockchain, GDPR, conflicts and privacy-friendly blockchain applications. Then the session will be split into working groups which will discuss how to find the right balance between immutability, privacy and the right to be forgotten. The working groups will present their results and discuss them with the audience. The session will conclude with a lightning talk on standardization initiatives.
