PANews reported on June 5 that according to Bitcoin.com, Alexandre Stachtchenko, chief strategy officer of the French crypto exchange Paymium, warned that the latest draft guidelines of the European Data Protection Board (EDPB) may make Bitcoin illegal in the EU. The draft regards blockchain public keys as personal data and requires them to be deleted under certain conditions, but the characteristics of blockchain technology make the data tamper-proof.

The EDPB explicitly stated that "technical impracticability cannot be used as a reason for non-compliance with the GDPR" and pointed out that if fine-grained data deletion cannot be achieved, it may be necessary to "delete the entire blockchain." Stachtchenko criticized this position as being out of touch with technical reality, and the anonymization scheme is not recognized by existing regulations. The public consultation period ends on June 9. If the draft is passed, Bitcoin may be deemed illegal because it cannot meet data deletion requirements.
