The European Data Protection Board (EDPB) draft guidelines pose a significant threat to Bitcoin’s legal status within the EU. Their interpretation of blockchain public keys as personal data necessitates their deletion, potentially undermining Bitcoin’s tamper-proof nature. This poses considerable risks for crypto projects and public blockchains reliant on immutability, including Ethereum. Alexandre Stachtchenko, Chief Strategy Officer at Paymium, warns that this approach is impractical, jeopardizing compliance with the General Data Protection Regulation (GDPR). He suggests the entire blockchain might need to be deleted if these guidelines are adopted. The potential for legal ramifications and market disruption is a cause for concern among industry stakeholders as they navigate this uncharted legal territory.
