Blockchain has been an emerging technology, which comprises lots of fields such as distributed systems and Internet of Things (IoT). As is well known, blockchain is the underlying technology of bitcoin, whose initial motivation is derived from economic incentives. Therefore, lots of components of blockchain (e.g., consensus mechanism) can be constructed toward the view of game theory. In this paper, we highlight the combination of game theory and blockchain, including rational smart contracts, game theoretic attacks, and rational mining strategies. When put differently, the rational parties, who manage to maximize their utilities, involved in blockchain chose their strategies according to the economic incentives. Consequently, we focus on the influence of rational parties with respect to building blocks. More specifically, we investigate the research progress from the aspects of smart contract, rational attacks, and consensus mechanism, respectively. Finally, we present some future directions based on the brief survey with respect to game theory and blockchain.

区块链系统中的合理协议和攻击

区块链是一种新兴的技术,它包含许多领域,例如分布式系统和物联网(IoT)。众所周知,区块链是比特币的基础技术,其最初动机来自经济动机。因此,可以从博弈论的角度构建区块链的许多组件(例如共识机制)。在本文中,我们重点介绍了博弈论与区块链的结合,包括理性的智能合约,博弈论的攻击以及理性的挖掘策略。换种说法,参与区块链的理性方设法最大化其效用,他们根据经济动机选择了自己的策略。因此,我们专注于理性方对构件的影响。进一步来说,我们分别从智能合约,合理攻击和共识机制等方面研究了研究进展。最后,基于对博弈论和区块链的简要调查,我们提出了一些未来的方向。
