Sentiment Protocol: A Decentralized Protocol Leveraging Crowd Sourced Wisdom

Anton Muehlemann

Abstract: The wisdom of the crowd is a valuable asset in today's society. It is not only important in predicting elections but also plays an essential rôle in marketing and the financial industry. Having a trustworthy source of opinion can make forecasts more accurate and markets predictable. Until now, a fundamental problem of surveys is the lack of incentives for participants to provide accurate information. Classical solutions like small monetary rewards or the chance of winning a prize are often not very attractive and also do not prevent multiple entries or randomly filling in answers. In this work, we present a framework that solves both problems via a customizable incentivization framework. Apart from predicting events, this framework can also be used to govern decentralized autonomous organizations.
