Guidelines on Processing of Personal Data Through Blockchain Tech (2025)

The European Data Protection Board's updated guidelines on blockchain-based personal data processing carry direct implications for practitioners developing decentralized local LLM systems or federated learning architectures. As the AI community explores distributed inference models where computation happens locally while maintaining shared model updates across networks, understanding GDPR and related regulations becomes essential.

These guidelines address critical questions relevant to local deployment: how personal data can be processed in decentralized systems, what privacy guarantees are required, and how to maintain compliance when data flows across jurisdictions through blockchain or distributed ledgers. For practitioners building privacy-preserving local AI systems—whether federated learning frameworks, distributed inference networks, or privacy-first deployment architectures—these guidelines provide the regulatory framework within which such systems must operate.

The EDPB guidelines are particularly important if your local LLM deployment involves any coordination across multiple nodes, user data processing, or European users. Practitioners should review the document to understand obligations around consent, data minimization, and right-to-erasure in distributed settings. This is especially relevant for those developing community-driven or cooperative local AI infrastructure.
