# EIP-7732 (ePBS) Breakout #14 Meeting Notes

- **Attendance**: Smaller group due to holidays. Representatives from:
- Prysm: Potuz & Terence
- Teku: Stefan
- Nimbus: Kira contributing to Nimbus for ePBS

- **Fork Choice Simplification**:
- Potuz will open a spec PR for the latest fork choice simplification based on Francesco's "all-in-one" design.

- Prysm: Finishing Devnet5 spec first, then rebasing ePBS.
