Mechanisms for modeling trust and reputation to improve robustness and performance in multi-agent societies make up a growing field of research that has yet to establish unified direction or benchmarks. The trust research community will benefit significantly from the development of a competition testbed; such development is currently in progress under the direction of the Agent Reputation and Trust (art) Testbed initiative. A testbed can serve in two roles: 1) as a competition forum in which researchers can compare their technologies against objective metrics, and 2) as a suite of tools with flexible parameters, allowing researchers to perform easily-repeatable experiments. As a versatile, universal experimentation site, a competition testbed challenges researchers to solve the most prominent problems in the field, fosters a cohesive scoping of trust research problems, identifies successful technologies, and provides researchers with a tool for comparing and validating their approaches. In addition, a competition testbed places trust research in the public spotlight, improving confidence in the technology and highlighting relevant applications. This paper lays the foundation for testbed development by enumerating the important problems in trust and reputation research, describing important requirements for a competition testbed, and addressing necessary parameters for testbed modularity and flexibility. Finally, the art Testbed initiative is highlighted, and future progress toward testbed development is described.
