| Abstract(in English) | In recent years, blockchains have become more and more popular，and it is important to identify the security risks to blockchains. There are various types of attacks on blockchains，including poisoning attacks on blockchains，and among the poisoning attacks，there are attacks on blockchains such as distributing forgeries of digital artworks that are managed using NFT (Non-Fungible Token). Currently, transactions using NFTs are actively conducted，and the risk of the aforementioned poisoning attack is increasing，so it is necessary to analyze the risk of NFT transactions. In this study, we analyzed the risk of trading digital artworks using NFTs，and found that there are two types of attack risks: fake attacks and double distribution attacks. In addition，we proposed an architecture for more secure NFT transactions to prevent these attacks. |
