区块链矿工决策的稳定性分析与控制

Stability analysis and control of decision-making of miners in blockchain

Kosuke Toda, Naomi Kuze, Toshimitsu Ushio

摘要:

为了维护基于区块链的服务并确保其安全性,如何确定挖矿奖励以增加参与挖矿的矿工数量是一个重要问题。我们提出了一个动态模型的决策矿工使用进化博弈的方法,并分析了所提出的模型的平衡点的稳定性。该模型由一阶微分方程描述。因此,它是简单的,但它的理论分析提供了一个洞察决策的特点。通过对平衡点的分析,我们发现了平衡点的跨临界分岔和滞回现象。我们还设计了一个控制器,根据参与矿工的数量来确定挖矿奖励,以稳定所有矿工参与挖矿的状态。数值模拟表明,在设计参数的选择上存在一个折衷。

英文摘要:

To maintain blockchain-based services with ensuring its security, it is an important issue how to decide a mining reward so that the number of miners participating in the mining increases. We propose a dynamical model of decision-making for miners using an evolutionary game approach and analyze the stability of equilibrium points of the proposed model. The proposed model is described by the 1st-order differential equation. So, it is simple but its theoretical analysis gives an insight into the characteristics of the decision-making. Through the analysis of the equilibrium points, we show the transcritical bifurcations and hysteresis phenomena of the equilibrium points. We also design a controller that determines the mining reward based on the number of participating miners to stabilize the state that all miners participate in the mining. Numerical simulation shows that there is a trade-off in the choice of the design parameters.
