Web3

Web3 is a term for the next evolution of the internet, where applications are built on decentralized protocols rather than controlled by centralized companies. The core idea is that users should own their data, digital identity, and assets instead of renting them from platforms like Google, Meta, or Amazon.

Web Evolution:

Web3 Core Principles: - Decentralization: No single entity controls the infrastructure - Self-Sovereign Identity: Users control their own credentials and data - Token-Based Economics: Services governed and incentivized through tokens - Permissionless: Anyone can build and participate without gatekeepers - Trustless: Interactions verified by code, not institutions

Web3 Technology Stack: - Layer 1: Base blockchains (Ethereum, Solana, etc.) - Layer 2: Scaling solutions (Arbitrum, Optimism, Base) - Storage: Decentralized file storage (IPFS, Arweave, Filecoin) - Identity: ENS, Lens Protocol, DID standards - Frontend: Traditional web tech connecting to blockchain via wallets

Web3 Applications Today: - DeFi: Financial services without banks - DAOs: Community-governed organizations - NFTs: Digital ownership and creator economies - Gaming: Player-owned in-game assets - Social: Decentralized social networks (Farcaster, Lens)

Criticisms: Critics argue that Web3 is largely rebranded cryptocurrency speculation, that many "decentralized" apps rely on centralized infrastructure (AWS, Infura), that the user experience is poor compared to Web2, and that blockchain does not solve most real-world problems better than existing technology. Proponents counter that Web3 is still early and that similar criticisms were made about the early internet.
