• Interoperability: Apps and platforms can connect easily.
• Trustless Transactions: Blockchain removes the need for middlemen.
• Native Payments: Cryptocurrency integration.

Chapter 3: Key Technologies Behind Web3

1. Blockchain – The backbone of Web3; decentralized, secure ledgers.
2. Cryptocurrencies – Native currency of Web3 (Bitcoin, Ethereum, etc.).
3. Smart Contracts – Self-executing agreements on blockchain.
4. Decentralized Applications (dApps) – Apps that run on blockchain.
5. NFTs (Non-Fungible Tokens) – Proof of ownership of digital assets.
