🧑🏫 Lesson 11: Ethereum and Smart Contracts 🤖📜
If Bitcoin is digital gold, then Ethereum is a whole blockchain computer! 💻
It hosts applications, games, DeFi, and even NFTs. Let's figure out how it works 👇
🌐 What is $ETH ?
• It is not just cryptocurrency, but a platform for decentralized applications (dApps)
• Works like a global computer, where code executes without servers and intermediaries
• The second most popular crypto after BTC 💪
📜 What is a smart contract?
A smart contract is a program that automatically executes the terms of an agreement.
No lawyers, no trust — only code 🤝
Example: want to sell an NFT for 1 ETH?
The smart contract will verify the payment and transfer the token — all fair and instant ⚡
🧬 Ethereum Standards
Many tokens and standards have emerged on Ethereum:
• ERC-20 — standard for regular tokens (e.g., USDT, LINK, UNI)
• ERC-721 — standard for NFTs (unique tokens: images, items, tickets)
• There are others: ERC-1155, ERC-4626, etc.
🧩 Conclusion
Ethereum is not just crypto, but a whole ecosystem 🌍
Smart contracts make possible #defi , #nft , #DAO , and much more.
If you want to understand where #Web3 is heading — start with Ethereum! 🚀
