There are hundreds of thousands of products, companies, books, movies, and events happening every day. It is a real hassle to find the best product when we have to trust feedbacks and reviews from unknown or known parties without any consensus mechanism. The existing review system is completely broken and unfair as there is no trustless check system to avoid paid, promoted, or faked reviews. We propose a decentralized and trustless review protocol built on Elrond Network where content-checkings are incentivized for meeting a consensus. Posters and Checkers are rewarded based on the quality of their work with CHECKR token.
