full-blockchain-solidity-course-js README

The project's README from github.com/smartcontractkit/full-blockchain-solidity-course-js. As one markdown file: README.md.

Update: Head to Cyfrin Updraft

ℹ️ Important: This repo is no longer actively maintained as there have been changes in Hardhat tooling. The video is out of sync with the code, and you can still follow along with the video, but you will likely need to troubleshoot the changes in the tooling and dependencies. Note also that best practices have evolved since this video was made.
If you'd like to continue your training with more up-to-date material, you can take a look at Cyfrin Updraft. That content is developed with love by Patrick & Cyfrin <3. However note that Cyfrin Updraft training uses Foundry, not Hardhat, so there will be tooling changes involved.

All code references have both a javascript and a typescript edition.

Recommended Testnet: Sepolia

We have updated the repos to work with Sepolia due to Rinkeby and Kovan being sunset, and Goerli being a disaster. Let us know if any of the changes break stuff!

Full-blockchain-solidity-course-js
这是什么？一门免费的完整课程，讲解区块链概念、Solidity 智能合约开发，以及使用 JavaScript（同时提供 TypeScript 版本）构建全栈 Web3 应用。由 FreeCodeCamp 制作。
这是智能合约库还是完整课程？这是一个课程仓库，包含配套的视频讲解，以及逐课的代码（Remix、Hardhat、HTML/JS、NextJS 项目），而不是可复用的库。
我该如何开始学习这门课程？观看课程视频链接，并按课程顺序使用本仓库中的代码逐课跟做。每一课（Remix、Ethers.js、Hardhat、NextJS 等）都有各自的文件夹，大多数课程还有对应的 TypeScript 版本。
开始前我需要准备什么（钱包、测试网资金、工具）？你需要 Node.js、一个 MetaMask 钱包，以及从水龙头领取的测试网资金。由于 Rinkeby 和 Kovan 已停止服务，Goerli 也存在问题，本课程现在以 Sepolia 测试网为目标。
这门课程还是最新的吗？不是了。由于 Hardhat 工具已经变化，课程不再积极维护，视频与代码已不同步，你很可能需要自己排查依赖和工具变化带来的问题。更新的版本在 Cyfrin Updraft 上。
这门课程适合谁？适合几乎没有区块链基础的初学者，目标是从零开始，学会编写、测试和部署 Solidity 智能合约，以及全栈 Web3 前端。
这门课程的代码可以安全地部署到主网吗？不可以。仓库明确警告，所有课程代码仅用于演示，未经审计，不应视为可用于生产环境。
这门课程会依次讲解哪些内容？从 Remix 中的区块链基础和 Solidity 入门开始，接着学习 Ethers.js 和 Hardhat 项目（Fund Me，以及 Chainlink VRF 彩票），然后是部署在 IPFS/Filecoin 上的 NextJS 全栈前端，最后讲解 ERC20 代币和 DeFi/Aave 借贷。
README 顶部提到的 Cyfrin Updraft 是什么？它是同一位讲师（Patrick Collins 与 Cyfrin）推出的后续课程，仍在积极维护。如果你希望获得比这个已归档仓库更新的 Web3/Solidity 培训，它是推荐的选择。
这门课程用到了哪些 Chainlink 服务？Fund Me 项目涉及 Chainlink Price Feeds/Oracles；构建可验证随机的智能合约彩票时，涉及 Chainlink VRF 和 Chainlink Keepers。
