Mining Pool Selection under Block WithHolding Attack

In current Proof-of-Work (PoW) blockchain systems, miners usually form mining pools to compete with other pools/miners in the competition. Forming can give steady revenues but will introduce two critical issues. One is pool selection, where select join order maximize their revenues. The a Block WithHolding (BWH) attack, inject part of hash/mining power into obtain additional without contributing process attacked pools. Reasoning that BWH attack have significant impacts on we therefore investigate selection issue presence this paper. particular, model as an evolutionary game and find Evolutionarily Stable States (ESSs) (i.e., stable population states) solutions. Previous studies investigated problem from perspective managers neglected (attacking revenues), leading less accurate insightful findings. This paper, however, focuses payoffs carefully takes attacking consideration. To demonstrate how solved, consider scenario further case one attacks each other. results paper show attract more by launching significantly affects populations.
