Development of MMORPG games in a decentralized environment

Abstract

This thesis examines methods which could be used for developing MMORPG games so that there is no single entity that could arbitrarily control game mechanics, virtual assets or other game aspects. The theoretical part systematically analyzes the usual aspects of MMORPG games, then the principles of decentralized cryptocurrencies are presented, and one of them, Ethereum, is analyzed in more detail. Based on this theoretical knowledge, methods are proposed on how to use Ethereum to implement the identified aspects of MMORPG games, and the restrictions which must be imposed on these aspects are recognized. The practical part then introduces a specific implementation of MMORPG game on Ethereum, which demonstrates the above methods. In conclusion, the chosen approach is compared to the games with a common client-server architecture, especially in terms of complexity and gaming costs. 1
