A Usability Analysis of the DAO Concept Based on the Case Study of a Blockchain Game

Abstract

Games based on a blockchain exist in all variants and facets, mostly as single- or multiplayer games. This chapter deals with the implementation of a multiplayer strategy game (Connect Four), using blockchain technology for decentralized data storage and the entire game logic. The focus is on the use of the decentralized autonomous organization (DAO) principle, for coordination and voting within the teams. The chosen game just stands as an example; other games or gamification approaches in which users can take decisions collaboratively can be used here. A web application was implemented acting as a central interface between players and the blockchain. Hence, it was possible for players to compete against each other in teams and to collectively decide the next move by participating in a roundly voting. With the help of a standardized questionnaire, answered by each player after each match, possible impacts of the voting mechanism on the usability were determined.
