# Week 1 Hello :) this is my Week 1 update for Ethereum Protocol Fellowship 6. This week I explored the relevent codebases along with **Pureth** and **Focil**. Along with that I went through the recent **ACDT** and **ACDE** calls. ## Checklist ### [Pureth EIP-7919](https://eips.ethereum.org/EIPS/eip-7919) Coverage : After going through the EIP, I saw that it's dependent on numerous other eips that explores various different ideas of **ssz serialization**. I tried to test the new proposed types like **StableContainer[N]**, **Profile[B]** as in [EIP-7495](https://eips.ethereum.org/EIPS/eip-7495) and **ProgressiveList** as in [EIP-7916](https://eips.ethereum.org/EIPS/eip-7916) with my friend [Soubhik](https://github.com/Soubhik-10). I also followed the discussion in associated with it in discord. ### [FOCIL EIP-7805](https://eips.ethereum.org/EIPS/eip-7805) Coverage: I decided to go through this eip and follow the discussion both in **ethereum-magicians** and discord. To better understand the changes thats needed in both EL and CL , I checked the specs and also explored the linked prs in **Prysm**, **Geth** , **Nethermind** etc. Finally decided to move with **FOCIL** as my choice of project to work on. ### Studied[ Reth](https://github.com/Rimeeeeee/reth) Closely: Along with all these,wrapped few of my prs for reth. Notably liked working on **send_raw_transaction_sync** which decodes and send transaction and waits for the receipt.Opened few more :) ## Next Week Plan: * Continue to learn FOCIL. * Try to draft a proposal and submit. :) ## Resources * [EIP-7805 Fork-Choice Inclusion Lists (FOCIL)](https://ethereum-magicians.org/t/eip-7805-fork-choice-inclusion-lists-focil-as-a-candidate-for-glamsterdam/24342) * [Focil](https://meet-focil.vercel.app/) * [Focil PR](https://github.com/ethereum/execution-specs/pull/1214) * [Beacon Change for Focil](https://github.com/ethereum/consensus-specs/blob/e678deb772fe83edd1ea54cb6d2c1e4b1e45cec6/specs/_features/eip7805/beacon-chain.md) * [Eip-7495 Own Implementation](https://github.com/Soubhik-10/r_ssz/tree/master/src/eip7495) * [Eip-7916 Own Implementation](https://github.com/Soubhik-10/r_ssz/tree/master/src/eip7916) * [ACDT and ACDE calls](https://www.youtube.com/@ethereumprotocol)
