In a global corpus DePIN network built from the bottom up by 100,000 LingoPods, a sub-network of 100 LingoPod nodes can accumulate 50 hours of diverse speech data in a particular one language within just 30 minutes. Compared to centralized corpus collection methods, this Web3.0 approach is more efficient and decentralized (without middlemen taking a cut). Users receive fair token rewards after their data contributions are validated by ReviewDAO.
