Farcaster, a decentralized social networking protocol, recently raised $150 million in funding, with a valuation of $1 billion. Its advantages lie in its long-term vision, data autonomy, open-source concept, and seamless integration with Web2 users. By implementing a paid registration and community-driven approach, Farcaster rejects low-quality users and creates a pure social environment. The $5 registration fee for the Warpcast client effectively prevents ad spammers and bots, resulting in a community with high-quality content and incentivized rewards for bloggers. Farcaster still needs to address the registration barrier and content distribution and discovery mechanisms in the Chinese market. Overall, Farcaster is a prototype for the future of Web3 social networking, and more excellent products based on it are expected to emerge.
