What is Web 3.0?

Web 3.0, also known as the decentralized web, is the next evolution of the internet that focuses on blockchain technology, smart contracts, and decentralization. Unlike Web 2.0, where data is controlled by centralized platforms, Web 3.0 aims to give users control over their data, identity, and digital assets.

What are Decentralized Applications (DApps)?

DApps (Decentralized Applications) are applications that run on blockchain networks instead of centralized servers. They leverage smart contracts to automate processes and remove intermediaries. Examples include Uniswap (decentralized finance), OpenSea (NFT marketplace), and Axie Infinity (blockchain gaming).

How to Become a Web 3.0 Developer?
