Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request optimizes the handling of Payload Timeliness Committees (PTCs) for the Gloas fork by implementing a direct caching mechanism within the BeaconState. This change aims to enhance performance and simplify the access patterns for PTCs by storing currentPtc and previousPtc directly in the state, rather than relying solely on EpochCache. The state transition logic has been updated to manage the rotation of these cached committees, ensuring their availability and correctness throughout slot processing.

Highlights

• Payload Timeliness Committee (PTC) Caching: Introduced direct caching of currentPtc and previousPtc within the BeaconState for the Gloas fork, moving away from EpochCache for immediate access.
• Refactored PTC Logic: Moved PTC computation and retrieval functions from EpochCache into dedicated utility functions (packages/state-transition/src/util/gloas.ts and packages/state-transition/src/util/seed.ts) to centralize and streamline their usage.
• State Transition Integration: Updated the state transition and upgrade processes to correctly initialize and rotate the cached PTCs at each slot and epoch boundary for the Gloas fork.
• Specification Alignment: Modified specrefs to reflect the new caching mechanism, function locations, and updated specifications for get_ptc, compute_ptc, and get_indexed_payload_attestation.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

removed since PTC assignments are not stable for the next epoch, see ethereum/beacon-APIs#586

[nflaig]

we now longer need to cache this since we only need to access the last slot of previous epoch which is now cached in the state via state.previous_ptc

Code Review

This pull request introduces cached Payload Timeliness Committees (PTCs) to the state, enhancing the efficiency of payload attestation validation. It involves modifications across several files, including adding a new function for computing PTCs, initializing and rotating PTCs within the state, and updating relevant data structures and processes. The changes aim to optimize performance by caching PTC data for faster access during validation.
