| Abstract(in English) | The use of CryptoAssets for money laundering and settlement of fraudulent and illegal transactions due to strong anonymity is increasing rapidly, and measures to prevent misuse of CryptoAssets are required. The governments of each country are tightening regulations through legal systems and guidelines, such as implementing reliable KYC (identity verification) for CryptoAssets business organizations. However, since many CryptoAssets can be transferred between users without going through CryptoAssets business organization, the effect of such measures will be limited. We think that, for preventing the misuse of CryptoAssets, it is necessary to incorporate a mechanism for identifying and tracking users in the CryptoAssets system. In this paper, we consider the method of identifying and tracking the transaction creator (CryptoAssets system user), targeting the asset transfer method P2PKH of the Bitcoin system. |
