## Rational Actor Assumption

The rational actor assumption posits that participants in a market will always act to maximize their own economic gain. This is the cornerstone of game theory in economics and is applied rigorously to the design of blockchain protocols.

By assuming that every user, validator, and trader is a rational actor, designers can create incentive structures that make honest behavior the most profitable path. If a protocol can be proven secure under the assumption that all actors are rational, it is considered robust against selfish manipulation.

However, real-world behavior can sometimes be irrational or driven by external factors, which is why protocols must also include safeguards against extreme scenarios. This assumption simplifies complex human interactions into predictable patterns that can be modeled mathematically.
