Abstract: The primary risks associated with game account trading include the exposure of personal information and the potential for account retrieval. In a system leveraging blockchain technology, specifically Ethereum combined with the InterPlanetary File System (IPFS), personal and game-related information is kept confidential. This system ensures that only the respective users have access to their personal data on the blockchain. Furthermore, upon the completion of a trade, the information associated with the account can be altered once, enhancing security. Additionally, the landscape of video game trading, particularly in China, is evolving rapidly. With the growth and development of the video game industry in the region, it has become increasingly challenging to trade game accounts. This complexity is largely due to the emergence of various policies and regulations that aim to safeguard user data and maintain the integrity of game ecosystems. The blockchain-based system provides a more secure and efficient way of handling these transactions, mitigating risks associated with traditional trading methods. By employing decentralized technologies, this innovative approach ensures greater privacy, security, and compliance with regulatory standards, thus revolutionizing the realm of game account trading.
