闪电：支付渠道的博弈论
Ride the Lightning: The Game Theory of Payment Channels
摘要：
引入支付渠道是为了解决各种突出的加密货币可扩展性问题。多个支付渠道在区块链之上构建了一个网络，即所谓的第2层。在这项工作中，我们通过网络创建游戏的镜头分析支付网络。我们确定中间性和接近中心性作为支付网络的核心概念。我们研究的拓扑结构时出现的球员自私的行为，并确定参数空间中，他们构成了一个纳什均衡。此外，我们确定的社会最优依赖于介数和接近中心的相关性。在可能的情况下，我们限制了无政府状态的无政府代价。我们还简要讨论了稳定的代价。
英文摘要：
Payment channels were introduced to solve various eminent cryptocurrency scalability issues. Multiple payment channels build a network on top of a blockchain, the so-called layer 2. In this work, we analyze payment networks through the lens of network creation games. We identify betweenness and closeness centrality as central concepts regarding payment networks. We study the topologies that emerge when players act selfishly and determine the parameter space in which they constitute a Nash equilibrium. Moreover, we determine the social optima depending on the correlation of betweenness and closeness centrality. When possible, we bound the price of anarchy. We also briefly discuss the price of stability.
