Rust 版本的 Jeiwan/blockchain_go: blockchain-rust

您好！

我也是一名区块链的初学者，看到了您翻译的这个 blockchain_go 项目，觉得非常有学习实践价值；正好对于rust也有一点了解，就尝试参考 blockchain_go 的源代码用 rust 把这个项目重新写了一遍，希望对其他人来说也可以起到一点参考的作用：

Github repo 链接：[github.com/yunwei37/blockchain-rust](https://github.com/yunwei37/blockchain-rust)

目前七个部分的大致工作已经基本完成，后续还会继续完善；

Review the linked blockchain-rust repository and its stated seven completed parts alongside this tutorial. The issue does not name a file, test, or requested change, so first determine whether the project should add or document this external Rust implementation. Done would require an agreed scope and a clear location for any resulting documentation.
