TUDA (Tutor’sDiary) is a token-incentivized platform for private tutors’ education services which focuses on 3 key areas: 1. Increase teachers’ earning potential and power. The knowledge sharing communities among tutors leveraged by the wisdom of the crowd to assess the value of content and distribute tokens to it (referred to as “Proof-of-Brain”). 2. Improve trust and comfort given to parents about teachers & teaching strategies. An interaction between tutors and students and transparent transaction of talent/fees ensured by a blockchain technology. 3. Curated Educational Contents. “Smart and social” content creation and curation of educational materials enhanced by tokenized incentives (called the “rewards pool”).
