[AndreaDiazCorreia]

Description

Implement the rating system for users to rate their counterparties after completed trades, following the Mostro protocol specification for reputation management.

Implementation Requirements

1. Rating functionality:

interface RatingSystem {
  async rateUser(order: Order, rating: number): Promise<MostroMessage>;
  async getRating(pubkey: string): Promise<UserRating>;
  async handleRatingConfirmation(orderId: string): Promise<void>;
}

interface UserRating {
  totalReviews: number;
  averageRating: number;
  lastRating: number;
  maxRating: number;
  minRating: number;
}

2. Rating message handling:

interface RatingMessage {
  order: {
    version: number;
    id: string;
    action: Action.RateUser;
    content: {
      rating_user: number;
    };
  };
}

Testing Requirements

describe('RatingSystem', () => {
  it('should submit ratings correctly');

  it('should handle rating confirmations');
  it('should track rating history');
});
