Blockchain data is retained and stored without the ability to delete, which brings potential violation of the right to be forgotten under Article 17 of the GDPR. "This is a completely new area for regulators that raises a ton of issues," Jones Day Partner Jörg Hladjk said, noting how data protection authorities must address potential liability, legal bases for processing and how to exercise data subject rights.
