Farcaster's open data, leveraging Optimism blockchain, ensures transparency and user control, with off-chain hubs enhancing scalability and cost-efficiency. Its Frames feature enables interactive dApps, boosting engagement (40,000 DAUs by October 2024). However, its hybrid model may limit full decentralization, and Warpcast's dominance could stifle third-party apps. Lens Protocol, built on Polygon, offers a modular social graph with NFT-based profiles, empowering creators with data ownership and monetization. Its permissionless access since February 2024 drove 22,000 DAUs, but on-chain storage raises costs, and fragmented UX across apps like Orb and Hey confuses users. Farcaster excels in UX and growth, while Lens prioritizes decentralization but struggles with scalability and adoption.
