On September 12th, Vana, a data AI platform powered by Paradigm, announced the launch of KLEO, a browser extension designed to give users control over their data and allow them to benefit from their online activities. Kleo uses a unique proof-of-contribution algorithm that assesses the uniqueness, intelligence, and importance of a user's actions to determine the quality of the user's data. The higher the quality of the data, the more rewards are earned each month. Kleo captures web page content and interactions, encrypts this data using public key cryptography, and securely uploads it to the cloud. Users have complete control over their data.
