The Ethereum Foundation highlights two critical EIPs for the Hegota upgrade, focusing on resilience against quantum attacks by 2029.
The Ethereum Foundation's Protocol Cluster has identified two crucial Ethereum Improvement Proposals (EIPs) for the upcoming Hegota upgrade, which is part of its ongoing efforts to enhance the network's capabilities. Among 62 proposed EIPs, FOCIL (EIP-7805) and Frame Transactions (EIP-8141) have been classified as S-tier, indicating their essential nature.
In a recent announcement, the Protocol Cluster shared two significant posts highlighting the upgrade's priorities, including a comprehensive tier list for the proposed EIPs.

Developers are also focusing on making Ethereum resilient against potential quantum attacks, with a target date set for December 2029. The FOCIL mechanism will involve a committee of validators curating transaction lists, thus enhancing resistance to censorship by ensuring compliance with specific criteria for transaction inclusion.
The Frame Transactions proposal aims to streamline account verification, transaction execution, and gas payment by integrating account abstraction directly into the protocol. This innovation is designed to provide cryptographic flexibility, enabling accounts to adapt to new signature schemes without necessitating hard forks for each algorithm, thereby addressing vulnerabilities posed by quantum computing.
“Safely implementing both key proposals and testing their interactions is the main engineering commitment for Hegota,” stated the Protocol Cluster.
Should challenges arise with either S-tier proposal, developers would prefer to adjust the Hegota timeline rather than exclude them.
This prioritization process involved around 60 researchers and engineers from nine teams within the Protocol Cluster, marking the first unified ranking of proposals rather than individual assessments.
Further Proposals and Quantum Resistance
Several other proposals received A-tier ratings, indicating their potential inclusion in the upgrade, contingent on developers managing the workload effectively. EIP-8369, which outlines transaction profiles for FOCIL guarantees, remains non-mandatory and will require further extensions for binding rules.
Additionally, A-tier proposals EIP-8250 and EIP-8272 enhance Frame Transactions by introducing separate nonces for enhanced privacy and enabling private operations that reference recent blockchain states, respectively.
As part of its strategy for achieving full quantum resistance by December 2029, the Protocol Cluster has committed to a series of updates, including Hegota, followed by a sequence labeled I*, J*, K*, and L*. Phase I* will introduce a registry of post-quantum public keys, while J* aims to implement minimal viable post-quantum protection.
The current roadmap anticipates the need for multiple updates to maintain the network's functionality amid quantum threats, with developers recognizing that merely releasing hard forks will not suffice to meet the ambitious deadline.
“Simply releasing hard forks consecutively is insufficient to meet the December 2029 deadline,” the cluster noted.
To ensure timely progress, the development of upcoming updates will proceed in parallel, with specifications for I* advancing while research for subsequent phases continues. This initiative aligns with Ethereum co-founder Vitalik Buterin's emphasis on quantum resistance as a growing priority.
