Cooperation Mechanism in Blockchain by Evolutionary Game Theory

In the blockchain network, to get rewards in blockchain, participants pay for various forms of competition such as computing power, stakes, and other resources. Because need a certain cost, individual cooperate maintain long-term stability jointly. course competition, game between each has appeared invisibly. To better understand design cooperation mechanisms, this paper, we constructed framework with different willingness, using evolutionary theory, complex network games. We analyzed how behavior potentially develops cost payoff. consider expected benefits normal growth major factor. Considering malicious betrayers, needs be maintained early stage. Numerical simulation supports our analysis.
