Social Choice Theory

Social choice theory is a branch of economics and mathematics that analyzes how individual preferences, values, or interests can be aggregated into a collective decision. It examines the properties of different voting systems, such as their fairness, stability, and susceptibility to strategic manipulation.

In the realm of cryptocurrency, social choice theory provides the framework for evaluating how protocols reach consensus on governance changes. It helps identify the inherent trade-offs between different voting mechanisms, such as the impossibility of creating a perfectly fair system that satisfies all desirable criteria.

By applying these theories, protocol designers can better understand the potential outcomes of their governance models and the risks of systemic failure.
