## Adversarial Actor Modeling

Adversarial Actor Modeling is the practice of simulating the actions of malicious participants to identify potential weaknesses in a system. By assuming that users will act to maximize their own gain, even at the expense of the protocol, designers can uncover vulnerabilities in incentive structures and code.

This includes modeling scenarios like Sybil attacks, where one entity creates multiple identities to gain influence, or bribery attacks, where actors are paid to vote against the protocol's interests. This modeling approach is essential for stress-testing governance and consensus mechanisms before deployment.

It moves beyond "happy path" design to ensure that the system remains secure even when confronted with intelligent, profit-seeking adversaries. This proactive stance is vital for the survival of decentralized systems.
