Week 9 Recap: In-Depth Understanding of Optimism's Opstack and Sequencer
Introduction
In the ninth week, I delved deeper into the concepts of Optimism's Opstack and Sequencer. This article aims to summarize these topics and provide practical code examples and explanations.
My Contribution
To gain a deeper understanding of these concepts, I organized some ideas and the current path into a series of manuscripts. I plan to compile the contents of these manuscripts into GitHub repositories later to help others understand the entire code flow more quickly. Currently, I have already created two GitHub repositories to host this content: Understanding Optimism Codebase and Understanding Optimism Codebase (CN).
Opstack Concept
Opstack is a core component of Optimism responsible for handling various operations on Layer 2. Specific specifications and details can be found in the Optimism official GitHub repository.
Key Features
- Efficiency: Opstack improves transaction processing speed through optimized algorithms and data structures.
- Security: It employs multiple encryption techniques to ensure data security.
- Scalability: Opstack can easily scale to handle more transactions and operations.
Sequencer's Working Principle
Sequencer is the component responsible for generating Layer 2 blocks.
How Layer 2 Blocks Are Generated
- Transaction Retrieval: The Sequencer first fetches pending transactions from the transaction pool.
- Transaction Verification: It performs necessary verifications on the transactions to ensure their validity.
- Transaction Sorting: Transactions are sorted based on a specific algorithm.
- Transaction Packaging: Sorted transactions are packaged into a new Layer 2 block.
- Block Submission: Finally, the Sequencer submits the newly generated block to Layer 1.
Conclusion
By gaining an in-depth understanding of Opstack and Sequencer and organizing my thoughts into manuscripts, I have contributed not only to a deeper understanding of Optimism's internal workings but also to the creation of GitHub repositories to facilitate a quicker understanding of the entire code flow for others. Currently, I have created two GitHub repositories, one for the English version Understanding Optimism Codebase and another for the version in my native language, Understanding Optimism Codebase (CN).
