Hello World | Learn Solidity (0.8) - By Example

Описание: 🚀 Welcome to Web3 Development with Solidity!
In this beginner-friendly tutorial, you’ll write your first smart contract using Solidity 0.8, the most popular language for building decentralized applications (dApps) on the Ethereum blockchain.

Whether you're a Web2 developer or completely new to blockchain, this video will walk you through the Hello World contract and a simple counter app to help you get started with smart contract development.

🧠 Why Migrate from Web2 to Web3?
Web2 platforms are centralized, meaning users don't truly own their data or identity. In Web3, apps run on decentralized networks like Ethereum, providing:

💼 True ownership (wallet-based identity)
💸 Built-in payments via smart contracts
🔒 Security, transparency, and censorship resistance

By learning Solidity, you're stepping into a new era of the internet — where you can build open, trustless, and permissionless applications.

📚 What You’ll Learn in This Video:
✅ Writing a basic Solidity Hello World contract
✅ Understanding pragma solidity ^0.8.0
✅ How public state variables work in Solidity
✅ Deploying and testing with Remix IDE
✅ Building a simple Counter contract (increment/decrement logic)
✅ How these smart contracts represent the foundation of dApps
