# Week3

## Summary

My main task this week is on based rollup and preconfirmations, and learning revmc and llvm stuffs while doing evm benchmarks

## Attend Meetings

* Attend Chinese EPF meeting.

## Weekly Updates

* Add evm_mlir and revmc to [evm-bench](https://github.com/Akagi201/evm-workshop/tree/master/bench), use same fibonacci contract bytecode, and refined code structure.

Look at the fastest result, it's as expected.
