Ethereum’s GDPR-oriented proposal leverages zero-knowledge proofs to redefine consensus validation, ensuring that validators no longer handle raw personal data

Quotes that support claims

zk-SNARK Execution: Validators verify succinct proofs instead of raw transactions—“verify, don’t see”—dramatically reducing on-chain personal data exposure.

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.
