Hey my name is joohhnnn. Here is my update on EPF4 Week 6. ## Week 6 Work Summary: In-depth Understanding of Taiko and Layer2, and Systematic Review of the Optimism Sequencer Support for ERC 4337 Bundlers Project ## Overview This week, I delved into the principles behind Taiko and had multiple discussions with the team about Layer2 technologies. Additionally, I completed a systematic review of the [Optimism Sequencer Support for ERC 4337 Bundlers project](https://github.com/joohhnnn/cohort-four/blob/master/projects/Optimism-Sequencer-Support-for-ERC-4337-Bundlers.md). ## ***Key Activities*** ### Code Review and Smart Contracts * Participated in the code review of Taiko's new alpha smart contract. * Gained a deep understanding of the role of Layer1 smart contracts in Layer2. * Conducted some code reviews here(https://github.com/taikoxyz/taiko-mono/pull/14541#pullrequestreview-1586423657). ### Issue Submission and Layer2 Protocols * Submitted several issues concerning Layer2 protocols. * Detailed issue submission can be found here(https://github.com/taikoxyz/taiko-mono/issues/14452#issuecomment-1694971139). ### Client Layer Code and Issues * Took a deep dive into the client layer code of Layer2. * Raised some issues here(https://github.com/taikoxyz/taiko-client/issues/365#event-10131753435). ### Optimism Sequencer Support for ERC 4337 Bundlers Project Review and Presentation * Completed a systematic review of the project, including overall structuring, documentation writing, and PPT editing. ### Next Steps * The architectural work on the Taiko project is essentially complete. Planning to expand research on the Optimism network next week.
