Web3 social media is transforming online interaction with decentralized platforms like Lens Protocol and Farcaster. Built on blockchain, they prioritize user ownership, privacy, and monetization via tokens or NFTs. Users control their data and identities through crypto wallets, bypassing centralized servers. Trends include token-gated communities and interoperable protocols. Challenges like complex UX and scalability persist. Adoption grows, but Web2 giants dominate. Web3 could reshape social media by 2030 if user-friendly solutions emerge.
