How Crypto-Shredding Reconciles Immutable Logs with GDPR's Right to Erasure

Event sourcing architectures and GDPR Article 17's requirement to erase personal data on demand are fundamentally incompatible.

This approach transforms GDPR compliance from an operational nightmare into an architecturally sound design while providing added security benefits like tenant isolation.
