# EPF5: Week 3 After two rough weeks in which I could not properly focus on EPF for personal reasons, I can finally post my first update. Hi, I'm Daniel! This week, I mostly focussed on Distributed Validator Technology (DVT) and Maximum Effective Balance (MaxEB). ## Distributed Validator Technology I looked a bit into DVT, however the specification repos[^1][^2] I found have not been updated in a while, so I am unsure if they represent the current state. I also investigated the approaches SSV[^ssv] and Charon[^charon]. While this topic is very interesting, I am unsure if it is considered "Core Development", as they build on top of Ethereum (or more specifically, on top of CL APIs). However, it would be nice to have a common spec and multiple clients available for DVT. ## Maximum Effective Balance I studied the MaxEB EIP-7251[^3] (and the Electra CL specs[^5]), and it ended up being more complex than I anticipated. Being included into Pectra for a while, I expect client teams to have the implementation mostly ready. On the other hand, the spec tracking issue[^4] seems to indicate that there are quite a few open questions and spec tests to consider, so this might still be a good topic to get involved with. ## Miscellaneous I looked a bit into the project ideas proposed by the Lighthouse team, and caught up with the current state of affairs in Lighthouse. ## Next Week I want to look further into MaxEB, especially from a testing point of view. Furthermore I will look more into DVT to further understand the underlying BFT mechanism and to check out if some "EPF appropriate" project can be started relating to DVT. Ultimately, I think my project will involve one of the two, so hopefully I can decide on one and start to flesh out a proper project proposal next week.
