Proof of Usefulness Score
Category Standard

HarperDB is a verifiable, Series A funded distributed data platform with significant market traction (130k+ deployments, Serent Capital backing) and high technical utility. It solves genuine problems in edge computing and database convergence. However, the submission quality was exceptionally poor, containing verifiable falsehoods ('everyone', 'most people have used my product') which negatively impacted the Response Quality and Traction verification scores. Despite the low-effort submission, the project's actual real-world utility and verified footprint justify a high score comparable to established mature technology brands.
