なぜブロックチェーン分析では一度サービスに入った資金をそれ以上追跡できないのか
Chainalysis Reactorなどのツールがあれば、暗号資産(仮想通貨)のアドレス間の資金の流れを追うことが容易になります。ある2者間のトランザクションを分析するだけでなく、盗難資金や違法な活動に関連する資金がどこに流れているのかを追跡するのにも大きな効果を発揮します。犯罪者は捜査官を惑わすために、複数のアドレスを使って高速に資金を移動することが多いものの、ツールがあれば対抗できます。 取引所のハッキングにより盗まれた資金が2つの中間ウォレットを介し別の取引所に流れたという例を、以下のReactorグラフで示します。 1つ目の中間ウォレットから2つ目の中間ウォレット、あるいは2つ目の中間ウォレット(Intermediary wallet 2)から取引所(Exchange 2)の入金アドレスへの資金の流れを追うのは難しくありません。Reactorで、ウォレットのSending Exposure(送金方向のつながり)を見て、気になるサービスカテゴリをクリックすれば、具体的にどの送金相手に資金が流れたのかを確認できます。以下の画像は、Intermediary wallet 2からExchange 2への資金の流れを追うときの例です。 右側のSending Exposureのチャートのうち、”exchange”とラベルが付けられている部分をクリックすれば、特定の取引所が表示され、どの入金アドレスに送金されたのかがわかります。 しかし、その資金がExchange 2に入った後どうなったのかは同じ手順では知ることができません。以下の画像は、犯人のExchange 2の入金アドレスにおけるSending Exposureのチャートを示します。 …
