HackerNoon Projects of the Week: MetaCoreX, ZKX Helix, and Tripvento

This edition of Projects of the Week highlights three standout builds from the Proof of Usefulness Hackathon: MetaCoreX, ZKX Helix, and Tripvento. Each project demonstrates practical value by addressing real-world problems: from secure peer-to-peer transactions to interactive learning tools and real-time data observability, reinforcing the importance of building products grounded in actual utility rather than hype.
