Web3, or Web 3.0, is the new generation of the Internet aimed at making the web more decentralized, secure, private, and user-centric. Hereâs a clear and structured overview:
đ Simple definitions
Web1: Static Internet (1990-2005). You read pages.
Web2: Interactive Internet (2005-today). You participate (social networks, YouTube, etc.), but the data is controlled by giants like Google or Meta.
Web3: Decentralized Internet. You control your data, your identity, your money â often via blockchain.
đ Key principles of Web3
Decentralization: No intermediaries, data is on the blockchain.
Tokenization: Use of cryptocurrencies and NFTs to interact, own, or reward.
User control: You own your data and digital identity.
Smart contracts: Automatic programs that run on the blockchain (e.g. Ethereum).
Interoperability: Apps (dApps) can work together thanks to blockchains.

Technical complexity for beginners
Scalability still limited
High transaction fees (depending on the blockchain)
Scams and unregulated projects
đŻ Use case example
