Applications of Game Theory in Blockchain: A review

This review explores the application of game theory in enhancing blockchain technology across three key domains: security, smart contracts, and Internet of Things (IoT) integration. Game-theoretic models, such as stochastic, evolutionary, and non-cooperative games, address blockchain security by analyzing strategic interactions to mitigate threats like DDoS and block withholding attacks, optimizing incentives for honest behavior. In smart contracts, models like extensive-form and Bayesian games ensure trust and efficiency by enforcing credible commitments and managing irrational behaviors in decentralized systems. For IoT-blockchain integration, Stackelberg and Markovian games enhance security, privacy, and resource allocation in resource-constrained environments. The review highlights scalable solutions, including trust management and secure data exchange, while identifying challenges like computational complexity and the need for adaptive models.
