# EPF - Week 5 ### Project proposal This week I continued to study ePBS specification notes. I wanted to create a project proposal on implementing ePBS in Lighthouse. I contacted with a mentor from Lighthouse who is also working on ePBS. He explained to me that ePBS requires a lot of refactoring and quite a few architectural changes that will permeate through the whole codebase of Lighthouse. Unfortunately, the mentor is going on a long holiday and won't be able to help, and the scope of the changes doesn't look like something I could be able to figure out on my own. So, It seems that right now is not a good time for ePBS in Lighthouse. I'm still thinking about which project to pick up. There are other people that are also working on Lighthouse (I'm only aware of 2 so far) - maybe I can join them. ### Study Continued studying ePBS. Also, to study about Ethereum broader, I looked into the data availability problem, DAS, cryptography used in DAS, zk and optimistic rollups' architecture and EIP-4844. ### Plans for the next week - Either decide on a new project or find a team with a project where I could make meaningful contributions.
