Eugenio Reggianini GDPR-driven proposal, under the PeerDAS architecture, restricts data availability nodes to storing only short-lived, anonymous data fragments

Quotes that support claims

The execution layer would operate as processors relaying only encrypted or blinded data, while the consensus layer would solely validate commitments and zero-knowledge proofs. Lastly, the data availability layer, under PeerDAS, would store only anonymous shards for limited timeframes, bringing them in line with GDPR’s data minimization principle.

What PET help to achieve in that context? Before: Every execution node saw full transaction payloads and could be a controller. After: Transactions are encrypted or blinded on submission; relays and builders never see plaintext.
