# Week 3 EPF Update (Polishing Up Proposal)

## Reth FOCIL Proposal

I spent a good amount of time putting together my project proposal draft and working on slides during this week's proposal time during office hours. As a result, my technical progress has been somewhat muted.

## Reth Implementation Work

I've been continuing to make progress by rebasing Jacob’s work on the latest Reth commit. I was able to contribute some commits, implement ILs into the engine API, use Reth types to better specify ILs, and integrate ILs into the payload builder.

Currently, I’m stuck implementing `engine_newPayload` because the new Reth implementation no longer passes the execution sidecar, as it did in Jacob's implementation, making it impossible to validate that the ILs are being adhered to. I’m working on reworking the logic and trying to find the most idiomatic and Reth-aligned way to implement this change, so as not to introduce a regression.

## Next Steps

- Continue rebasing and get an updated Reth client with a basic implementation
- Polish the project proposal and prepare for the presentation
