Eugenio Reggianini, as part of efforts to ensure GDPR compliance, through privacy-by-design protocol changes, enables zk-SNARKs to allow validators to verify transactions without viewing raw 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.

Zero-Knowledge Succinct Non-Interactive Argument of Knowledge (zk-SNARKs) can also help improve privacy as they involve validators confirming succinct cryptographic proofs rather than viewing transaction payloads, dramatically reducing onchain data visibility.
