# EPF5 Dev Updates - Week 3


### Office Hour Highlights

This week, we had the privilege of listening to Advaita and Agnish from Nimbus, both past EPF participants. They shared their experiences participating in the Fellowship and the work they are doing at Nimbus.


### Learning Activities

**Core Protocol and Account Abstraction:**
I have been deeply engaged in learning about various subjects related to the core protocol and delving into Account Abstraction.

To better understand the Ethereum Protocol and the underlining architecture. I delve deeper by studying topics on Consensus layer, Execution layer, the ongoing protocol research and roadmaps. I learnt about the different Consensus and Execution clients powering the Ethereum protocol.

**Node Operation Workshop:**
I watched a video from a past workshop delivered by Mario Havel on how to run a node. He demonstrated how to run a node locally on your machine using GETH and Lighthouse. He also discussed the Euphemery testnet and its setup.

**Consensus Client:**
I viewed another past video on Consensus Clients delivered by Paul Harris from ConsenSys. He discussed Teku, a consensus client written in Java.

**Protocol Research:**
I watched a video on Protocol Research by Barnabé Monnot. He discussed the current state of the protocol, various research areas, and ongoing projects such as Blobs to enhance rollup transaction costs. He also covered block building, validators, Beacon, and validator proposals.

**Devnet and Testnet Testing:**
I watched a past workshop on testing on devnet and testnet by Paritosh. He explained the need for devnet testing and prototyping, available testing tools, and the DevOps environment for local testing. One of the tools he mentioned was Kurtosis, a DevOps tool for building, testing, and managing complex, distributed systems.


### Personal Development

**Go Programming Language:**
This week, I took a crash course on the Go programming language. I decided to learn Go now because most of the protocol repositories I have checked are written in Go, Rust, C, and other unfamiliar languages. Learning Go has been a great experience, and I now feel confident reading code written in Go.


### Exploration and Research

As part of my explorations, I reviewed several resources, both written and videos, related to ERC-4337 Account Abstraction. I aimed to understand the work done so far and the current state of Account Abstraction.
