自從網路發明後，接觸資訊方式更加容易，從而大大影響人們的生活方式，在這資訊爆炸的年代遊戲帳戶已經不再單單只是作為一個記憶體上的電磁紀錄，玩家努力遊玩付出的心血甚至是對遊戲的儲值，讓遊戲帳號有了價值甚至能拿來當成商品販售，網路的普及雖然帶來了許多便利之處，但與此同時也帶來了許多風險，其中之一便是網路詐騙案層出不窮，交換帳戶、先給帳戶後匯錢，各種私下交易先拿到帳戶或者是匯款就逃之夭夭的案例屢見不鮮，除了私下交易的詐騙，市面上現有的中心化遊戲帳號交易平台也存在著許多不合理之處。
近年來拜區塊鏈的技術逐漸成熟所賜，智能合約橫空出世，智能合約使得程式能夠去中心化執行，為去中心化系統帶來了更多的可能性，本研究希望藉由區塊鏈的技術來建造一個去中心化的遊戲帳號交易平台，借助智能合約的特性達到保存資料上、修改資料的公正性以獲取遊戲公司方、買方、賣方三方的信任，從而改進現有中心化遊戲帳號交易平台的缺失

After internet was invented,it’s easier to contact information,therefore changing people lifestyle intensely.At this era of information explosion,game account is not just an electromagnetic records on memory.Because of players’s hard work and depositon,game account is more valuable,it even can sell in nowadays. Internet penetration not only brings lots of benefits but also risks, one of that risks is internet fraud.Except for problems about transaction in private,there is also something unreasonable at existing centralized game account transaction platform.
Blockchain technology has become more and more mature recently,especially after the invention of Smart Contract.Because of Smart Contract,programs can be excuted decentralized.This reserch developed a decentralized game account transaction platform.With the help of characteristic of Smart Contract ,the platform guarantee the fairness of saving data and updating data to improve existing game account transaction platform.
