+### Summary of Scarb: The Package Manager
 
+**Scarb** is Cairo’s package manager designed for both Cairo and Starknet projects. It simplifies development by handling dependencies, compiling code, and integrating with tools like Foundry.
+
+#### **Scarb Workflow**
+1. **Initialize** a project with `scarb new`, generating a `Scarb.toml` file and a basic project structure.
+2. **Add Code** to the `src` directory.
+3. **Add Dependencies** via `scarb add`.
+4. **Compile** the project using `scarb build`, converting it into Sierra code, the intermediate layer between Cairo and CASM.
+
+#### **Cairo Project Structure**
+- Projects follow a modular structure where each package has a `Scarb.toml` manifest file and a `src/lib.cairo` file. 
+- Packages can include external libraries and modules, which are declared in the `Scarb.toml` file.
+
+Example project structure:
+```
+my_package/
+├── src/
+│ ├── lib.cairo
+├── Scarb.toml
+```
+
+#### **Building and Adding Dependencies**
+- **Build** projects using `scarb build`, which generates the compiled Sierra code.
+- **Add dependencies** by editing `Scarb.toml` or using `scarb add`. Dependencies can be hosted on GitHub or other sources and pinned to specific commits for consistency.
+
+#### **Components (since version 2.3.0)**
+Components in Scarb allow for reusable modular add-ons that extend contracts without rewriting logic. For instance, ownership functionality can be separated into a component and plugged into various contracts.
+
+#### **Example of Adding a Component**
+A typical Starknet contract can use components like `ownable_component` for ownership management, ensuring reusable and cleaner contract design.
+
+#### **Key Commands:**
+- `scarb new <project_name>`: Initialize a new project.
+- `scarb build`: Compile Cairo code into Sierra.
+- `scarb add <dependency>`: Add a dependency from a Git repository.
+- `scarb clean`: Remove build artifacts.
+
+#### **Conclusion**
+Scarb is a powerful tool in the Cairo ecosystem, helping developers efficiently manage packages, dependencies, and code. With more experience, developers can fully leverage its capabilities to enhance their Starknet projects. Components, in particular, make it easier to build modular, reusable contract logic.

+
+**Katana: A Local Node for Starknet Development**
+
+**Katana** is a tool developed by the Dojo team to aid in local development for Starknet. It allows developers to run a local Starknet environment for testing and interacting with smart contracts without needing to rely on public testnets. This local node is highly beneficial for fast, iterative contract development and debugging.
+
+### Features of Katana:
+- **Local Development & Testing**: Katana provides a local node, making it easier to test contracts, similar to the starknet-devnet (a public testnet maintained by Shard Labs). 
+- **Contract Interaction**: It enables developers to deploy and interact with contracts in a local setting. Examples of contract interaction using Katana can be found in resources like *The Cairo Book*.
+- **RPC Integration**: Katana supports Remote Procedure Calls (RPC), allowing communication between nodes and making it possible to interact with your local node via tools like Infura or Alchemy.
+
+### Getting Started with Katana:
+1. **Installation**: Katana can be installed using the `dojoup` installer with the following commands:
+ ```bash
+ curl -L https://install.dojoengine.org | bash
+ dojoup
+ ```
+ After installation, verify it using `katana --version`.
+
+2. **Starting a Local Node**: Launch a local Starknet node with specific parameters such as the number of accounts and seed:
+ ```bash
+ katana --accounts 3 --seed 0
+ ```
+ This creates prefunded accounts for testing, with output displaying their addresses, private and public keys, and the URL for the JSON-RPC server (e.g., `http://0.0.0.0:5050`).
+
+3. **Persistence**: The local node does not store data permanently, meaning all information is erased after the node stops. To stop the node, simply use `Ctrl+C`.

+`Felt252Dict<T>`允许“重写”任何键对应的值。
+
 当实例化`Felt252Dict<T>`后，所有的键关联的值被实例化为0。意味着如果读取一个不存在的数据则会返回0，而不是错误或者未定义的值。也意味着无法从字典中删除数据。
 
+### 2024.09.26
+
+##### 字典底层结构
+
+`Cairo`使用Entry列表来实现`Felt252Dict<T>`。每个Entry表示一条可以进行读取、更新、写入操作的记录。
+
+Entry结构包含三个值：
+
+1. `key`：用于识别字典的键值对
+2. `previous_value`：表示`key`的前一个值
+3. `new_value`：表示`key`更新的值
+
+如果使用高级结构来实现`Felt252Dict<T>`， 可以定义`Array<Entry<T>>`，`Entry<T>`的结构可以是：
+
+~~~rust
+struct Entry<T> {
+ key: felt252,
+ previous_value: T,
+ new_value: T,
+}
+~~~
+
+每一次与`Felt252Dict<T>`交互，就会注册一个新的`Entry<T>`：
+
+1. `get`操作将注册一个状态未改变的entry，然后`previous_value`和`new_value`存储为同一个值。
+2. `insert`操作将注册一个新的`Entry<T>`，`new_value`为写入的值，`previous_value`则是写入操作之前的值，如果是第一次写入，则为0。
+
+使用Entry列表展示了为何不存在重写，仅仅是在每次与`Felt252Dict<T>`交互创建一个新的内存单元。
+
+🌰例子：分别更新字典balance的'Alex'和'Maria'两个值：
+
+~~~rust
+balances.insert('Alex', 100_u64);
+balances.insert('Maria', 50_u64);
+balances.insert('Alex', 200_u64);
+balances.get('Maria');
+~~~
+
+上面的操作将产生如下entry列表：
 
+| key | previous | new |
+| :---: | :------: | :--: |
+| Alex | 0 | 100 |
+| Maria | 0 | 50 |
+| Alex | 100 | 200 |
+| Maria | 50 | 50 |
 
+这种实现方式意味着每次读取或者写入操作，都会遍历整个entry列表来查找与`key`相同的最近的那个entry。一旦找到对应的entry，它的`new_value`会被提取出来，并添加到新的entry的`previous_value`中。
 
+与常规语言不同，`Cairo`的目的之一是使用STARK证明系统生成计算完整性的证明。这意味着需要验证程序的执行是正确的，并且在`Cairo`限制的范围内。其中一个边界检查包括“**字典压缩**”（dictionary squashing），它需要每个条目的旧值和新值的信息。
