Optimistic Security Assumptions

Optimistic Security Assumptions are the core principles underlying protocols that prioritize efficiency by assuming that participants will act honestly unless proven otherwise. These assumptions are based on the economic incentive for users to report fraud, as they are often rewarded for successfully challenging malicious proposals.

If the underlying assumption ⎊ that there will always be an honest observer ⎊ is violated, the protocol faces significant risk. Therefore, these systems are usually paired with secondary security measures, such as economic bonds that are slashed if a challenge is proven fraudulent.

Understanding these assumptions is critical for risk assessment, as they define the boundaries of the protocol's trust model and the conditions under which the system remains secure.
