Ethereum researchers eye privacy-focused upgrades for 2027

Ethereum Foundation researcher Toni Wahrstätter has advocated for the inclusion of EIP-8141, known as Frame Transactions, alongside the already confirmed Fork-Choice Enforced Inclusion Lists (FOCIL). Frame Transactions would transition the network away from fixed fee structures toward a programmable format. This shift allows wallets to manage execution and gas payments directly, effectively removing the need for relayers—entities that currently create potential vulnerabilities by exposing wallet behavior to outside services.

FOCIL acts as a critical companion to this framework by ensuring that block builders cannot easily exclude specific privacy transactions. By allowing a committee of validators to enforce inclusion lists, the protocol provides a safeguard against selective censorship. While 66 proposals remain under consideration for the Hegotá upgrade, these two features represent a concerted effort to build protocol-level privacy protections that operate independently of external compliance intermediaries. Client teams are expected to finalize their preferences by September 10, following a scheduled technical review of competing account-abstraction designs.
