  248.                            <p class="info">This research explores the potential of blockchain technology to transform the digital economy of mobile games by enabling secure, transparent ownership of in-game assets. The study examines how blockchain can be used to facilitate the creation, trading, and ownership of non-fungible tokens (NFTs) within mobile games, allowing players to buy, sell, and trade unique digital items. Drawing on blockchain technology, game design, and economic theory, the paper investigates the implications of decentralized ownership for game economies, player rights, and digital scarcity. The research also considers the challenges of implementing blockchain in mobile games, including scalability, transaction costs, and the environmental impact of blockchain mining.</p>
