Web3 is the next stage of the internet characterized by decentralized networks that empower users to control their data and digital assets, in contrast to Web2's centralized platforms.
Advantages of Web3 include decentralized data ownership, peer-to-peer services, and elimination of intermediaries, offering users and developers more control, efficiency, and security.
Challenges in Web3 include scalability issues, user adoption barriers, and regulatory uncertainties, while opportunities include new business models, community engagement, and access to global markets for startups.
Web3's potential to revolutionize industries like finance and healthcare presents a significant opportunity for startups to innovate with decentralized applications, blockchain economies, and community-driven governance.
