European privacy regulators are working to bring blockchain technology in line with existing data protection rules.

The European Data Protection Board (EDPB) has approved a set of draft guidelines that outline how personal information should be handled on blockchains. These rules are meant to support the General Data Protection Regulation (GDPR), which protects the privacy of individuals across the EU.

The guidelines are now open for public feedback until June 9. They aim to limit how personal data is stored and accessed on blockchain networks.

The EDPB suggests that organizations plan for privacy early in the development of blockchain systems. This includes using tools and methods that reduce how much personal data is stored directly on-chain.

The draft also stated that people should clearly understand how their data is being used, who has access to it, and how they can request changes or deletion. Since blockchain records are permanent, the guidelines suggest workarounds, such as deleting encryption keys or storing data off-chain, to help meet these privacy requests.

Additionally, businesses must be clear about who is responsible for each part of the data-handling process. Before launching any system that uses blockchain to manage personal data, they should complete a Data Protection Impact Assessment.

The EDPB also warns against making personal data openly available on a blockchain where anyone can access it. Instead, access should be limited and controlled to prevent misuse or accidental exposure.
