Aptos 开发实战：从环境搭建到第一个 Hello World

引言

Aptos 区块链以其高性能和独特的设计为开发者提供了强大的工具。本篇学习笔记将带你一步步完成 Aptos 开发环境的搭建，并通过编写第一个 Hello World 项目，帮助你快速掌握 Aptos 开发的基础流程。从安装 Aptos CLI 到项目初始化与测试，本文为你提供了详细的实操指南，让你快速上手 Aptos 开发。

Aptos is a Layer-1 community-driven network, governed by the people who build on it from around the world. It’s decentralized. It’s fast. It’s blockchain at its best.

Aptos 区块链上的每个账户都由一个 32 字节的账户地址标识。与其他区块链中账户和地址隐式不同，Aptos 上的账户是显式的，需要先创建才能执行交易。可以通过将 Aptos 代币 (APT) 转移到 Aptos 来显式或隐式创建账户。

Aptos 上有三种类型的账户：

标准账户——这是一个典型的账户，对应一个地址和一对相应的公钥/私钥。资源账户- 一个没有对应私钥的自主账户，供开发者存储资源或上链发布模块。对象- 存储在代表单个实体的单个地址内的一组复杂资源。

帐户地址为 32 字节。它们通常显示为 64 个十六进制字符，每个十六进制字符为一个半字节。有时地址以 0x 为前缀。 Aptos区块链默认采用Ed25519签名交易。

Aptos 区块链存储三种类型的数据：

交易：交易表示区块链上的账户正在执行的预期操作（例如转移资产）。状态：（区块链账本）状态代表交易执行输出的累积，即存储在所有资源内的价值。事件：交易执行时发布的辅助数据。只有交易才能改变账本状态。

Aptos 开发环境配置
