| 1. 自我介绍 | ||
|
|
||
| 大家好，我是LGC，对OP比较感兴趣，希望通过这次共学，理解和认识 Optimism 的生态和相关信息知识，加深对 layer2 的理解 | ||
|
|
||
| 2. 你认为你会完成本次残酷学习吗？ | ||
|
|
||
| 会的！ | ||

||
| #### Layer2 | ||
|
|
||
| ##### layer2基础概念 | ||
| [What is layer 2?](https://ethereum.org/zh/layer-2/learn/) | ||
| 区块链有三个理想属性：decentralized、secure、scalable （三元悖论） | ||
|
|
||
| ==The main goal of scalability is to increase transaction speed (faster finality), and transaction throughput (high transactions per second), without sacrificing decentralization or security== | ||
|
|
||
| 以太坊当前面临的问题：低吞吐量（每秒15~30笔交易）、高gas费用、用户体验差。Layer2 的目标是通过将交易从主链转移到 Layer2 网络来解决这些问题 | ||
|
|
||
| [What is layer 2?](https://ethereum.org/zh/layer-2/learn/) | ||
| https://vitalik.eth.limo/general/2021/01/05/rollup.html Vitalik 详细解释了 Rollup 技术，包括 Optimistic Rollup 和 ZK-Rollup 的区别 | ||
|
|
||
| ##### L2技术类型 | ||
|
|
||
| * rollup | ||
| * Optimistic rollups：乐观汇总，使用欺诈证明 | ||
| * ZK rollups：使用有效性证明 | ||
| * state channels （状态通道） | ||
| * plasma | ||
|
|
||
| #### **OP Stack Overview** | ||
|
|
||
| [Vision - Optimism Official Blog](https://optimism.io/vision) | ||
| [Getting started with the OP Stack](https://docs.optimism.io/stack/getting-started) | ||
|
|
||
| The OP Stack is development stack thats powers Optimism，as Optimism evolves，so will the OP Stack. | ||
|
|
||
| Optimism Bedrock is the current iteration of the OP Stack. | ||
|
|
||
| The OP Stack of today was built to support [the Optimism Superchain](https://docs.optimism.io/superchain/superchain-explainer) (a proposed network of L2s) | ||
|
|
||
| ##### OP Rollup | ||
| [OP Rollup 扩容方案](https://docs.optimism.io/stack/rollup/overview) | ||
|
|
||
| * 区块存储：L2 区块保存到以太坊区块链中的一个非合约地址中`0xff00000000000000000000000000000000000010`，借此来降低L1 gas费用 | ||
| * 区块是EIP-4844 blob 提交，无法修改或审查，这就是 OP Mainnet 继承以太坊的可用性和完整性保证的方式 | ||
| * 区块生产：由`sequencer`单一管理 | ||
| * **Fault proofs** （故障证明）：challenge window持续7天 | ||
