By 2030, Web3 could underpin 20% of digital transactions, offering secure, user-owned data systems.
The Promise of Web3
Web3 enables true digital ownership—your data, art, or investments live on blockchains, not corporate servers. For example, creators use NFTs to sell art directly, bypassing middlemen, while decentralized apps (dApps) offer banking without banks, serving the 1.4 billion unbanked globally.
To get started with Web3:
- Set up a wallet: Use MetaMask to explore dApps or buy NFTs securely, starting with small transactions.
- Join communities: Engage on X or Discord to learn from Web3 pioneers and avoid scams by verifying project legitimacy.
