🧑‍🏫 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.
