EDPB Guidelines on GDPR-Compliant Blockchain Data Processing

The European Data Protection Board (EDPB) has released new draft guidelines to help organizations navigate GDPR compliance in blockchain projects. These guidelines focus on addressing challenges such as the immutability of blockchain records and data minimization principles. Key recommendations include using off-chain storage for personal data when possible, implementing data protection impact assessments (DPIAs), and ensuring proper legal bases for processing. The EDPB has opened these guidelines to public feedback until June 9, 2025. For companies working on blockchain or Web3 solutions, understanding these requirements will be crucial to avoid enforcement actions and build user trust.
