Maximum expected welfare is a concept in economics and game theory that refers to the optimal outcome in a system where the sum of all participants’ expected utilities is maximized. It represents a state where the collective benefit or satisfaction across all agents is as high as possible, considering the probabilities of various outcomes. This metric serves as a benchmark for evaluating system efficiency and fairness.
Context
In the design of blockchain protocols and decentralized mechanisms, maximizing expected welfare guides the creation of incentive structures that aim to benefit the entire network rather than just individual actors. This principle is applied when evaluating different consensus mechanisms, fee structures, or resource allocation algorithms to ensure the system’s long-term health and utility. Balancing individual incentives with collective welfare remains a central challenge in decentralized system design.
