# EIP-7732(ePBS) breakout #18

**Date:** Friday, February 28, 2025

#### **Key Decisions & Updates**
1. **Current Devnet Status**
- Devnet is stable without additional features
- Prysm still lacks inclusion proofs for blobs
- PTC attestation is working fine with the current design.

2. **Proposed Spec Updates**
- **Slot in Payload Envelope:** Already implemented in devnet.
- **Removing Payload Withheld from Payload Envelope:** Need to be updated in the spec.
- **Payload Attestation Format:** Convert to a Boolean value instead of `uint8`.
- **Random Mix Bug Fix:** Cache the last random mix before updating it.
- **Handling Empty Block Proposal & Withdrawals:** Should be managed at the client level via caching, but need to explicit this in the validator spec.
- **New Prefix for Staking Pool Transfers:** Builders must originate from a designated prefix.

4. **Forkchoice & Payment Mechanism**
- Francesco’s fork choice proposal introduces complexity in handling payments.
- Suggestion to defer payment mechanism changes until a comprehensive audit is completed.

5. **Action Items**
- **Review & Merge Justin’s PR** to align with older forks.
- **Open a PR for the small changes** (slot addition, payload attestation Boolean conversion, random mix caching).
- **Investigate the forkchoice model & payment mechanism**:
- If Francesco’s model is used, introduce an additional queue for payments.
- If current boosts are retained, further evaluation is needed.
- **Plan next devnet** between Prysm & Teku after PRs are merged.
