The problem RIFIL solves

• Anyone in the Filecoin ecosystem can use this for investing in valuable data generators and earn against that
• Storage Providers can earn more by storing data that would be high in demand using retrieval fees
• Clients can use this subsidy to store data for free or a negligible cost even without FIL+
• It can work with or without FIL+ and can also act as a replacement for FIL+
• Most useful for high impact data creators that whose data get used by a lot of other people like open source data models and weights
• Impactful for onboarding enterprise clients with high rate of retrievals

Challenges I ran into

Creating the incentive structure and finishing off in time.
