Introducing EulerCoin, a new cryptocurrency for Mathematicians, Educators and Learners

I am very excited to announce that our newest product is now available to everybody. is a BlockChain powered social learning platform. Users on the platform get rewarded with EulerCoin (the platform’s cryptocurrency) for creating and curating quality education content. The platform creates new tokens at a rate determined by mathematical rules that align the incentives between content creators, researchers, educators, teachers and students.

Go ahead and signup, post an article explaining some concept in mathematics or computer science / open problem / multiple-choice question / exercise. Content creators earn EulerCoin proportional to the number of likes (aka upvotes) of their content. More details of the token allocation and its game-theoretic analysis are coming soon in our white paper. We are planning an ICO soon.


Here are some examples of user generated content from our beta version:’s mission is to unleash the unlimited potential of such quality content creators, researchers, educators, teachers and students from all over world and make learning more engaging, efficient and effective.

At TrueShelf Inc, we now have two platforms:




How to learn English Vocabulary efficiently


As some of you know, I am now the Founder & CEO of TrueShelf Inc, an EdTech startup based in the Bay Area. TrueShelf is aimed at developing platform, content and products to aid intuitive, visual, social, adaptive and personalized learning. TrueShelf consists of two main components: TrueShelf Online Network and TrueShelf Apps. Read our FAQ for more details.

Today’s post is about TrueShelf apps, intuitive and visual learning apps that are carefully designed to help students learn specific concepts in a systematic and adaptive manner.

Recently we released our True Vocabulary app, our first adaptive learning app. The existing solutions to learn english vocabulary are either too hard-to-use and/or expensive and/or old-fashioned (e.g. flashcards). Our app is focused primarily on automatic personalization and ease-of-use. It has already received more than 25,000 downloads on the iOS app store. If you are preparing for GRE, SAT, GMAT, ACT, CAT or simply interested in improving your english vocabulary, True Vocabulary app provides an efficient and elegant step by step adaptive learning process. It is an intelligent personalized vocabulary tutor.

True Vocabulary uses an intelligent algorithm (based on the concepts of spaced repetition, Leitner system and lexical cohesion) to design adaptive multiple-choice vocabulary quizzes. Learning tasks are divided into small sets of multiple-choice quizzes designed to help you master the basic words before moving on to the advanced words. Words closely related to your hardest words are selected more frequently in the quizzes. For a fixed word, the correct and wrong answers are selected adaptively giving rise to hundreds of combinations. After each wrong answer, you receive a detailed feedback with the meaning and usage of the corresponding word. Coins, Gems and Levels are unlocked adaptively to motivate, evaluate and reward the learner.

Download our True Vocabulary App and let me know your feedback (or) suggest new features.


This is just the beginning of our journey to make education elegant, efficient and painless for hundreds of thousands of students and teachers. In future posts, I will talk more about TrueShelf’s vision and roadmap. Stay tuned.
