# **EPF Update 5 Week 4**

## Introduction
In this week's update, I will be discussing the recent developments in the project focus, building upon the topic I addressed in my previous update.

## Project Focus Shift
As mentioned earlier, there has been a shift in the project focus, and I'm excited to share that this shift is already in progress. This update will provide insights into the direction the project is taking.

## Collaboration with Nimbus Team
I've made significant strides in moving forward with the change in project focus. Specifically, I have engaged in productive discussions with Zahary from the Nimbus team. Our collaboration aims to kick-start efforts in extending Nimbus_eth2, the Ethereum 2 Beacon Chain written in the Nim programming language.

## Nim Proficiency
Following my commitment to adapting to this new direction, I dedicated time to learning Nim, as highlighted in the previous update. This learning endeavor has equipped me with the necessary skills to contribute effectively to the Nimbus project.

## Learning Resources
To deepen my understanding and skillset, I am delving into a set of valuable resources to help me learn about contributing to Nimbus. These resources include:

* [Nim Style Guide](https://status-im.github.io/nim-style-guide/)
* [Nimbus Auditor's Book](https://nimbus.guide/auditors-book/)


## Contributions to Nimbus
My primary goal is to make substantial contributions to the Nimbus project. While I have ambitious plans for the features I intend to work on, I will commence by focusing on a significant initiative.

### Implementing a Novel Append-Only Database
To kickstart my involvement in the Nimbus beacon node development, I will begin by creating a novel append-only database. This initiative aligns with my intention to undertake impactful tasks while adapting to the new project direction.

Stay tuned for further updates as I delve deeper into the intricacies of the Nimbus project and continue to make meaningful contributions. Your support and interest are greatly appreciated!
