DSC (Democratic Social Credit) is an advanced social credit system using futuristic technology. Individuals gain social credit points from doing socially good activities and lose social credit points from doing socially bad activities. E.g., individuals would gain social credit points from donating blood, giving to charity etc. and lose points from jaywalking or littering etc. Furthermore, in every social interaction, individuals must rate one another out of 5 stars depending on what they think of the person. The result of all these considerations is an aggregated "human score" out of 5 stars. Your human rating determines the prices you pay for goods, where your children can go to school, what areas you can buy houses etc.
