Blockchain, a cutting-edge technology, has brought significant innovations across various sectors. However, its interaction with data privacy raises complex issues, especially in light of the GDPR (General Data Protection Regulation).
Blockchain functions as an immutable and secure data ledger thanks to cryptography. Yet, this transparency is in tension with the GDPR, which sets limits on the retention of personal data. Unlike traditional conventions, the blockchain is designed to maintain data permanently. Nonetheless, the French Data Protection Authority has demonstrated that, through innovative technical solutions, it is possible to align blockchain with data protection regulations.
