Because the broader Ethereum ecosystem and its core rules evolve to handle information privateness issues, a brand new proposal recommends a modular compliance technique as a path to reconcile public blockchains with the European Union’s Normal Knowledge Safety Regulation (GDPR).
On June 9, a proposal drafted by Ethereum neighborhood member Eugenio Reggianini advised using modular structure for efficient information administration and privateness.
“By pushing private information to the perimeters (wallets and DApps), utilizing offchain storage with metadata-erasure, and splitting roles cryptographically, we are able to focus GDPR controller duties on a small set of entities, whereas the broader community turns into mere processors or falls out of scope,” Reggianini mentioned.
Ethereum’s transition to a modular structure may allow the combination of varied privacy-enhancing applied sciences (PETs), which, in response to Reggianini, can obtain GDPR compliance in permissionless blockchain environments.

Technical roadmap: PETs to the rescue
The proposal outlines a number of applied sciences already being built-in or proposed for Ethereum that assist cut back private information publicity, together with proto-danksharding (EIP-4844), which limits transaction blob lifespans to round 18 days, imposing storage minimization.
Zero-Data Succinct Non-Interactive Argument of Data (zk-SNARKs) may assist enhance privateness as they contain validators confirming succinct cryptographic proofs moderately than viewing transaction payloads, dramatically decreasing onchain information visibility.
Different PET integrations that would assist with GDPR compliance embrace Totally Homomorphic Encryption and Trusted Execution Environments (TEEs), multiparty computation (MPC), Proposer-Builder Separation (PBS) and Peer Knowledge Availability Sampling (PeerDAS).
Ethereum’s modular compliance technique
The proposal breaks down GDPR implications throughout the Ethereum community’s three layers: the execution layer, consensus layer and information availability layer.
The execution layer would function as processors relaying solely encrypted or blinded information, whereas the consensus layer would solely validate commitments and zero-knowledge proofs. Lastly, the information availability layer, beneath PeerDAS, would retailer solely nameless shards for restricted timeframes, bringing them consistent with GDPR’s information minimization precept.
By focusing information controllership on the applying layer and leveraging PETs, Ethereum can defend consumer privateness with out sacrificing its core rules, Reggianini claimed.
Nevertheless, the framework’s success will rely upon broad neighborhood adoption, developer buy-in, and potential alignment with EU regulators.
