Ethereum offered a new protocol design

The new proposal to ensure the confidentiality of Ethereum using modular architecture involves compliance with GDPR standards in the European Union and preserving the principles of decentralization.

“Public blockchains like Ethereum always face a problem: coordination of immutability and decentralization with the data protection rules. The transition to modular architecture, improved technologies for preserving confidentiality, offers a way to embed the principles of GDPR into the protocol itself, ”said the author of the proposal and member of the community Euchehenio Rezhenini.

In his opinion, moving personal data to the periphery (wallets and Dapps), using an offchain storage with the removal of metadata and sharing the roles of cryptographically, you can concentrate the duties of the GDPR controller on a small set of subjects, while a wider network becomes “just an executor or falls out of the sphere of influence”.

The main goal is to transfer the management of information to the relevant subjects of the applied level that decide to process personal data, Redzianini noted. At the same time, the infrastructure of a lower level (customers of execution and consensus) will process only anonymous or at least pseudonymous data.

“In fact, personal data should be transformed or abstracted before the level of blockchain is reached, and, of course, before they spread through the level of consensus,” the author of the initiative added.

He believes that the transition of Ethereum to the modular architecture can ensure the integration of various technologies for increasing confidentiality (Pet), which meet the GDPR standards.

Reginani also described a number of existing or planned decisions that will help in implementation. For example, proto-dankcharding (EIP-4844) limits the life expectancy of transaction blocks with data for up to 18 days, ensuring minimization of storage volume.

ZK-Snark technology will also help improve confidentiality, since it involves confirmation of brief cryptographic evidence by validators.

Among other Pet, the expert called completely homomorphic encryption and trusted executions, multilateral calculations, the separation of “offering” and “builders” and a sample of the availability of one -rat data.

Recall that in June, the non -profit organization Ethereum Foundation reduced part of the study and development team, focusing on key challenges and the main problems of the protocol.
