Web3, short for "Web 3.0", is the next generation of the internet where users have more control over their data, identity, and assets. It's powered by blockchain technology, which enables decentralization, transparency, and ownership without relying on centralized authorities like banks, governments, or tech giants.
🌐 Evolution of the Web
🔑 Core Principles of Web3
1. Decentralization
Data is stored on distributed networks (like blockchains), not on
centralized servers.
2. Ownership & Control
Users own their data and digital assets (e.g., NFTs, tokens)
through wallets.
3. Permissionless Access
Anyone with an internet connection can participate — no need for
approval.
4. Trustless Transactions
Smart contracts automate agreements without needing
intermediaries.
5. Native Payments
Uses cryptocurrencies (like ETH, BTC) instead of traditional
banking rails.
