2132 charsEuropean Data Protection Board Publishes Guidelines on Personal Data Processing Through Blockchain Technologies
On July 7, 2026, the European Data Protection Board (EDPB) published final guidelines on the processing of personal data through blockchain technologies. The guidelines provide clarity on how the General Data Protection Regulation (GDPR) applies to blockchain-based systems and distributed ledger technology (DLT) implementations.
The guidelines address key regulatory considerations for organisations deploying blockchain solutions that involve personal data processing. They establish principles and practical recommendations for controllers and processors using blockchain technology to ensure compliance with GDPR requirements. The guidance covers fundamental data protection obligations including lawful basis for processing, data subject rights, accountability measures, and technical safeguards specific to blockchain environments. The guidelines also address the unique challenges blockchain technology presents, such as immutability, decentralisation, and transparency, in relation to core GDPR principles including data minimisation, purpose limitation, and the right to erasure.
The EDPB developed these guidelines following a public consultation period, during which it received feedback from stakeholders across the technology, financial services, and regulatory sectors. The final version incorporates responses and clarifications from the consultation phase. Organisations implementing or planning blockchain solutions that process personal data should review the guidelines to ensure their systems and governance frameworks align with GDPR requirements. The guidelines are immediately applicable and provide interpretative guidance rather than introducing new legal obligations. Downloadable versions of the guidelines, including a tracked-changes document and the public consultation report, are available on the EDPB website.

On July 7, 2026, the European Data Protection Board (EDPB) published final guidelines on the processing of personal data through blockchain technologies.
The guidelines provide clarity on how the General Data Protection Regulation (GDPR) applies to blockchain-based systems and distributed ledger technology (DLT) implementations.
These guidelines provide a framework for organisations considering the use of blockchain technology, outlining key GDPR compliance considerations for planned processing activities. They provide an overview of the fundamental principles of blockchain technology, assessing the different possible architectures and their implications for the processing of personal data.
Furthermore, they clarify that the roles and responsibilities of different actors in a blockchain-related processing need to be assessed during the design of that processing and what elements need to be considered in this respect.
Depending on the purpose of processing for which blockchain technology is used, different categories of personal data may be processed. The guidelines highlight the need for data protection by design and by default, and adequate organisational and technical measures. They also provide examples of different techniques for data minimisation and for handling and storing personal data.
