Network simulation tool for bitcoin mining pool attack

Abstract

Nowadays, Bitcoin and other cryptocurrency increase their financial, and technical value. In decentralized network, a lot of miners are mining the cryptocurrency. In this paper, we focus on a mining pool, which is co-operation system of solo miners, and the distribution of mining pool and build network simulation framework for that. Since Bitcoin mining need massive computational resource, previous Bitcoin simulator also spends huge CPU/RAM resource to construct simulation network. However, we shows that we can change the simulation more efficient, and enable users to constitue various network topology easily and precisely. Moreover, we superinduce several attacker modules such as blockwithholding attacker or fork after withholding attacker. These attackers manipulate the vulnerability of a mining pool’s distribution system. For each attacker module, we validate the implementation of the module sources experimentally. Furthermore, we verify the theoretically calculated attacker’s unfair additi[o]nal reward in alternating sets of network environment.
