Economic Game Theory

Definition ∞ Economic game theory applies mathematical models to analyze strategic interactions among rational agents within economic contexts, including digital asset markets. It helps predict participant behavior and design protocols that align individual incentives with collective network security and efficiency. In cryptocurrency, it informs the creation of tokenomics and consensus mechanisms to prevent malicious actions. This analytical framework is essential for understanding the stability of decentralized systems.
Context ∞ The application of economic game theory is a central component in the design and evaluation of new blockchain protocols and decentralized applications. Researchers constantly refine models to account for novel attack vectors and market dynamics. A key discussion involves designing incentive structures that promote long-term network health and deter cartel formation among validators.
