Abstract

This work explores the performance/scalability issues of blockchain protocols. Some existing solutions present a new concept of DAG-oriented blockchain protocols to address this problem. In contrast, in this work, we investigate two unique DAG-oriented blockchain protocols PHANTOM and GHOSTDAG and make a security analysis of their designs. To this end, we develop a custom simulator that extends the open-source simulation tool to support multiple chains within the protocol. We have empirically shown that these protocols cannot work in realistic scenarios and need to be redesigned.
