# EPF - Week 2

#### Progress report

This week I have read [eth2book](https://eth2book.info/) up to part 3 (Annotated Specification) and learned a ton of new things.

And I also ran Reth + Lighthouse pair on Holesky. Since I want to implement ePBS on Lighthouse, I looked into consensus-specs and tried to run them against Lighthouse. Apparently there's a [special folder for this in the Lighthouse's repo itself](https://github.com/sigp/lighthouse/tree/stable/testing/ef_tests). While doing so I watched videos on running a node and consensus and execution specs from epf.wiki.

#### Plans

From the next week I will start studying [ePBS specification](https://github.com/potuz/consensus-specs/pull/2) and [other](https://mirror.xyz/barnabe.eth/QJ6W0mmyOwjec-2zuH6lZb0iEI2aYFB9gE-LHWIMzjQ) [articles](https://barnabe.substack.com/p/pbs) [on PBS](https://www.youtube.com/watch?v=T5BWw_IvPZo) and [ePBS](https://ethresear.ch/t/why-enshrine-proposer-builder-separation-a-viable-path-to-epbs/15710), and I will also continue studying about consensus layer at epf.wiki
