Reputation and Incentive Mechanism

The reputation score of a node nin_i can be updated based on its performance in completing tasks, denoted as PiP_i, and its historical reliability, denoted as HiH_i:

Ri(new)=γPi+δHiR_i^{(new)} = \gamma \cdot P_i + \delta \cdot H_i

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