Privacy by Blockchain Design

Privacy by Blockchain Design develops and consults on data privacy solutions for the disruptive and fastly growing blockchain ecosystem thus reducing the risk of heavy fines of EU supervisory bodies and mislead investments into innovative but legally non-compliant products.

"Our goal is not merely providing GDPR-compliance for Blockchain, but rather using Blockchain to raise data protection levels in the digital world to new dimensions"

Christian Wirth & Michael Kolain


Privacy with blockchains: in our view, blockchains can not only be GDPR-compliant, they can also help raise data protection levels and truly give back data ownership to individuals. As such, we see the Blockchain as a great tool for privacy and want to encourage the industry to take the lead in this area.

Blockchain Study about Blockchain by the European Parliament

The Study about "Can distributed ledgers be squared with European data protection law?" done by the European Parliament acknowledges our contributions to classify Blockchain as a case of Joint Controllership (Art. 26 GDPR), demanding and drafting a Blockchain-based system to monitor the data controller's compliance.

Journal of Banking and Financial Technology (Springer Verlag)

The Journal of Banking and Financial Technology (Springer Verlag) writes about our latest Paper: "Chrisitan Wirth et al., also showed [66] how blockchain design can be compatible with General Data Protection Regulation (GDPR) act."

DIN SPEC 4997 Privacy by Blockchain Design

A standardised model for processing personal data using blockchain technology

In February 2019, we won the DIN CONNECT competition, receiving funding from the German Institute for Standardization (DIN) to develop the first worldwide standard of its kind on handling personal data using blockchain technology.

Scope of the DIN SPEC: This DIN SPEC establishes general principles for and methods of handling personal data in blockchain ecosystems. It specifies technical and organizational measures for data protection while taking into account the principle of "privacy by design" as well as specifications that are inspired by legal frameworks, such as GDPR. The document defines relevant terms for both technical as well as legal experts and establishes a methodological framework that helps to identify types of data (encrypted and not encrypted) as well as methods of data processing that lead to a positive or negative classification as "personal data" in blockchain scenarios. This DIN SPEC is aimed towards establishing a high level of privacy in blockchain ecosystems. This document is applicable to all IT systems using blockchain technology.
