How Does the Immutable Nature of Blockchain Conflict with Regulatory “Right to Erasure” (GDPR)?

The immutable nature of a public blockchain, where once data is recorded it cannot be altered or deleted, fundamentally conflicts with the European Union's GDPR "right to erasure" (Right to be Forgotten). GDPR grants individuals the right to have their personal data removed under certain circumstances.

Since transaction data on a public blockchain is permanently recorded, fully complying with a deletion request is technically impossible, creating a major legal challenge for decentralized applications that process personal data.
