Design and Implementation of NFT Game Framework Based on Character Items

Abstract

Recently, there have been many P2E (Play to Earn) games with the concept of cashing in game items and making a model through game play. In some low-income countries, many game companies are creating their own mainnets and serving games within their ecosystems, as more money is made than when they work. Initially, NFT issuance was possible only when coding was possible. However, an NFT application program that does not require coding is produced and NFT is issued through the produced application program. However, since these applications deal with a large amount of picture files, there is a disadvantage in that the computer memory usage continues to increase if a large number of publishing tasks are performed at once. In this study, we intend to design and implement a new NFT Game framework to solve these problems. The designed framework aims to support the issuance of as many NFTs as desired even in low-end computers by organizing the existing problem, the ever-increasing memory. It also adds features to provide the ability to automatically distribute them to the open market. The framework proposed in this paper is designed as a Market System framework, Game framework, and NFT Converter framework, which serve each of the three types of functions. It was made based on C# and used a game developed with Unity 3D engine to apply it to the game engine. Item data was registered in the market by issuing NFT tokens using the framework. Token's Metadata was graded and classified with seven costume data information, six character setting information, and background screens, giving each scarcity. As a result of this study, it is expected that Unity-based games will use the framework to expand and apply NFT issuance in various forms.
