# Dev Update #4

My progress in the week of Oct. 31 - Nov. 4
## What I Have Done Since Last Update
Currently I have been working on two research projects with Barnabé: 
- [Rollup economics framework](https://efdn.notion.site/ROPs-RIG-Open-Problems-c11382c213f949a4b89927ef4e962adf?p=561d6340ad174195a335af6cc4e66bb7&pm=s), and
- [Ethereum economic model review](https://efdn.notion.site/ROPs-RIG-Open-Problems-c11382c213f949a4b89927ef4e962adf?p=53d8410e3fb642c5853424b8f79707ea&pm=s).

### Rollup economics framework
On the rollup economics project, I mainly conducted preliminary research on Arbitrum rollup protocol. The main goal is to understand Arbitrum rollup mechanism, how it works on the fundamental level and its fee economics. The result of this preliminary research is the following (on-going) post [:point_right: here](https://hackmd.io/@EagleEdge/Byoja3aVj). 
My teammate has been working on Optimism rollup and we had a meeting this Friday morning to discuss the progress we have made so far and next step plans.

In the meantime, I setup my [GitHub repository](https://github.com/EagleEdge/mainnet-rollup-economy) for collecting data on L1/L2 transactions using Infura web3 API. I was able to extract data on detailed block-level and transaction-level characteristics from both L1 and L2.

### Ethereum economic model review
My progress on Ethereum economic review model has been on cadCAD class on Ethereum economic model. I have finished cadCAD Bootcamp (Beginner Level) and about to start masterclass. 


## Work Plans for Next Week

### Rollup economics framework
I will continue working on preliminary research on Arbitrum rollup. This includes reading articles/posts on the subject, exploring dashboards for rollups and reviewing my teammate's work on Optimism protocol. 

In addition, I will work on parsing the data extracted from L1/L2 using my repository. We want to have as detailed data as possible for rollup economics analysis.


### Ethereum economic model review
For the economic model review, I have two main goals for next week. 
1. Continue reading on the subject, and
2. Finish at least three sections (total five sections) of cadCAD masterclass on Ethereum economic model.

## Status Update on My Reading List
My reading list has been expanding exponentially, so I will not post the list here. I plan to create a new note, exclusively recording my reading list and my progress with this reading list over the course of the program.
