Many cryptocurrency iholders believe that their anonymity and security are well protected and that hackers can't infiltrate their transactions. However, this is not the case. Some attacks, such as dust attacks or transactional malleability attacks, are not only hurt the security, but can also cause congestion in the Bitcoin network. In this project, we will locate attackers in the transaction network, study their pre-attack or early attack transaction behavior by machine learning, and then identify more potential attackers on the bitcoin network.

The main research question to be addressed is: Miner's behavior study.
