| Abstract(in English) | Some volunteers had performed tracking a huge amount of NEM leaked from CoinCheck by sending specific mosaics which no one can move except its sender. However, regarding a tracking mosaic, the analytics detail, such as the number of sent mosaics, the rate of sent mosaics and the time lag of sending mosaics, has not been clarified. In this paper, we survey about tracking of leaked NEM using mosaics and effect of such mosaic tagging system by analysing the block chain. The target period of our experiments is from Jan. 26th, 2018 when the CoinCheck incident happened. |
