title: EPF Cohort 4 - Week 3 Updates
---

Hey there, I am Manav Darji and these are my updates for week 2 (31/07 - 06/08).

The goal of this week was to have an initial discussion with the Mentors (Terrence and Potuz) from the Prysm team and plan out the next steps.

Updates
- Had a call for discussing a rough path ahead for the EPF fellows choosing the ePBS project.
- Gathered rough idea of all the sub-topics involved in the project. Also, got to know about some design descisions which I was earlier unsure about.
- Few of the sub-topics to look at are
- Builder onboarding and exit
- Handling validator withdrawals
- Beacon chain state transition
- Fork choice updates
- Networking components (like the gossiping of votes among the PTC committee)
- As suggested by the mentors, choosing one (or more) sub-topics and helping them with the spec + PoC (if requited) is the way ahead.
- For the beacon chain and fork choice details, they'll be sharing a blueprint of the spec which will help us attempt to fill in relevant details based on our interest.
- Continued reading the [eth2book](https://eth2book.info/) for more consensus terms and process like the attestation process, fork choice, beacon state transition, withdrawals, etc. required for me to choose what to focus on in PBS.
- Another problem statement which requires more validation is whether 512 a good number for the PTC committee or not. Moreover, how difficult it is to have a moving committee which keeps moving in and out of the global gossiping topic (overhead from a networking perspective). I am looking more into these specific topics.

#### Next steps

- Choose a specific sub-topic to work on and start with reviewing and helping with the spec.
