Reputation and Incentive Mechanism

The reputation score of a node $n_i$ can be updated based on its performance in completing tasks, denoted as $P_i$, and its historical reliability, denoted as $H_i$:

$$R_i^{(new)} = \gamma \cdot P_i + \delta \cdot H_i$$

Where $\gamma$ and $\delta$ are weight factors for current performance and historical reliability, respectively, and $R_i^{(new)}$ is the updated reputation score of node $n_i$.
