The choice of what selfish mining strategy to adopt as well as how to eclipse a victim is highly dependent on the network param- eters in which one is operating.
Webrevenue of an attacker under three strategies: Honest mining, which adheres to the Bitcoin protocol, SM1, and the optimal policies obtained by our algorithm. The three graphs correspond to γ = 0,0.5,1. We additionally illustrate the curve of α/(1−α), which is an upper bound on the attacker’s revenue, achievable only when γ = 1 (see ...
