This paper focuses on the evolutionary game between blockchain adoption decisions and consumer rights protection behavior on sharing economy platforms, aiming to provide support and guidance for platforms to formulate effective policies and measures. It introduces key theories and techniques required for constructing evolutionary game models, including replication dynamics equations and evolutionary stable strategies. By applying evolutionary game theory, an evolutionary game model is constructed for blockchain adoption decisions and consumer rights protection behavior, with corresponding replicating dynamic equations proposed for each. Numerical simulations are conducted to further analyze the factors influencing evolutionary stability. The results show that reducing the cost of blockchain technology investment and reasonably controlling expected returns, alleviating corporate competitive pressure, and lowering the risk coefficient of corporate operations can effectively increase the probability of corporate blockchain adoption decisions. In terms of consumer rights protection behavior, the difficulty of rights protection significantly inhibits consumers from choosing rights protection strategies, and the rights protection compensation coefficient is closely related to consumers’ motivation for rights protection.
