| Abstract: | 分散式金融(Decentralized Finance)在近年發展快速，其中也衍生了一些攻擊事件，價格供給預言機(Price Feed Oracle)是其中之重點，而2020年更發生了操縱價格的閃電貸攻擊(Flash Loan Attack)事件，本文利用時間加權平均價格的方法設計出價格處理公式WMA改(WMA_KAI)對價格做處理，使價格不只能加強對閃電貸攻擊之抵抗力，也不會偏離實際價格太遠，以達到安全且實用的價格供給。 With the rapid development of Decentralized Finance (DeFi), some attacks have come to pass, attack of Price Feed Oracle is the focus. In 2020, attackers made money via Flash Loan and price manipulation. This thesis uses Time-Weighted Average Price (TWAP) method to design a metric WMA_KAI to process price, so that the processed price can not only resist Flash Loan attacks, but also close to actual price to achieve safety and practical value. |
