📝 Short Notes: Web 3.0

• Definition: The third generation of internet services focusing on decentralization, blockchain technology, and semantic web capabilities
• Core Technologies: Blockchain, artificial intelligence, machine learning, and decentralized protocols
• Key Features: User data ownership, permissionless access, trustless interactions, and tokenization
• Differences from Web 2.0: Web 2.0 is centralized (controlled by corporations), while Web 3.0 is decentralized (user-controlled)
• Applications: Decentralized finance (DeFi), NFTs, decentralized autonomous organizations (DAOs), and blockchain-based social networks
• Advantages: Enhanced privacy, data security, censorship resistance, and direct peer-to-peer interactions
• Challenges: Scalability issues, high energy consumption, regulatory uncertainty, and user adoption barriers
